Into Unscientific

As a senior Goubi who came from later generations.

Xu Yun's emphasis on his own safety is undoubtedly much higher than anyone in this era.

after all

The halo never reminded him if he died in the dungeon, would his real self also lose his life.

Of course.

Judging from the many lives created by the halo.

The probability of this obliterating punishment mechanism is not high.

However, even if the death in the dungeon does not affect the real body, the completion of the task will inevitably be affected.

Xu Yun didn't want to see himself spend a lot of energy and time wasting, but at the last moment, he was slapped on the neck because he was not good enough, and he had no choice but to get a low score or even a guaranteed evaluation result.

Therefore, before entering the dungeon, he made a lot of preparations - such as the lime hidden in his cuff.

This vigilance reached a whole new level after the night raid on the Scottish camp.

therefore

As early as a long time ago, Xu Yun arranged some countermeasures.

for example

This body armor.

That's right.

long, long ago.

This body armor was actually not one of the two items he asked Avelyn to build, but the product of an agreement he had reached with Lister earlier.

That is the young man Xu Yun went to University College London to find after he visited Mr. Carl's family in London. (Hey, I didn't expect that)

In today's 1851, there are two well-known "Liszt" in the European continent.

One of them was Franz Liszt, a Hungarian.

He is a famous composer, pianist, conductor, great master of romanticism, and one of the most outstanding representatives of early romanticism.

Later generations call it the king of piano.

And another Liszt.

It was Joseph Lister.

This is the founder and promoter of surgical disinfection, known as the father of surgery.

He proposed that the lack of disinfection is the main reason for infection after surgery, and created a series of surgical norms.

In less than 10 years, the mortality rate after surgery was reduced from 45% to 15%.

Even many people in later generations have benefited from him, which can be called immeasurable merit.

In 1978, Mike Hart published "100 Celebrities Who Influenced the Process of Human History" and Lister ranked 60th.

Listeria, which made countless medical doctors crazy in later generations, was named after Lister.

So after learning that Xu Yun was visiting Liszt, some students thought that Xu Yun was going to engage in antibiotics.

But they ignore two problems:

First.

Xu Yun didn't have anyone who needed antibiotic treatment at the time, and if he wanted to save someone, he could have reproduced the allicin in the Northern Song Dynasty copy.

second.

Antibiotics can be distinguished from the photoelectric effect or cathode rays.

If this thing is invented in advance, the West will be the number one beneficiary, but it will be difficult for the East to enjoy this part of the dividend.

Therefore.

The purpose of Xu Yun's previous visit to Liszt was not related to the medical field, but to

Collaboration with the Lister family to produce body armor.

Everyone knows that Liszt is the father of surgery, and he was later made a baron for it.

Little is known, however, that Lister's father, John Jackson Lister, was a businessman in achromatic lenses.

His uncle is a rich merchant engaged in silk production, and his uncle produces and sells porcelain in France, belonging to a standard business family.

If not.

Liszt will not have the energy to do surgical research:

These days, almost all projects involving the word "research" require a large amount of capital investment.

For example, Gauss has the support of Archduke Ferdinand, and there are countless nobles who love him all his life. Cavendish is simply a local tyrant himself.

As for Abel and Babbage, the unlucky ones who don't have a benefactor father, even food and clothing are a problem.

So after meeting at that time.

Xu Yun directly provided a cooperation plan, which recorded part of the original body armor production process, and finally reached a cooperation intention with Liszt.

contract.

Xu Yun provided relevant production technology, and the Liszt family was responsible for production.

Xu Yun owns 40% of the sharing rights, and also enjoys the right to try out the finished product.

Among them, what Xu Yun really cares about is the latter, after all, this is his greatest life guarantee in the dungeon.

It's a pity that Xu Yun didn't know Aveline very well at the time, otherwise this matter could be entrusted to that ATM lady.

A full year has now passed.

Fortunately, the Liszt family finally came up with this finished body armor.

Of course.

Still in brackets, youth version.

well known.

In the long history of human weapon development, the search for "the strongest personal shield" has never stopped.

There is a saying that goes well:

"Every piece of equipment has its nemesis."

For bullets, body armor is one of the "old enemies".

The earlier body armor was "steel as armor", which resisted bullets through hard steel plates.

This kind of steel armor appeared very early, and to some extent it is no different from ordinary armor.

It was once popular at the end of the 16th century and spread to the whole of Europe.

Although it can play a bulletproof role, it is too hard, heavy and inconvenient to wear.

As a result, countries all over the world are gradually embarking on the road to find "lightweight soft armor".

The first thing that entered the human field of vision was cotton fiber.

in 1811.

Gaul once used more than 10 layers of cotton fibers to make "cotton carapace", which has a certain bulletproof ability.

Next is the modern Three Musketeers:

Silk at the end of the 19th century.

Manganese steel in the early 20th century.

And really modern ballistic materials like Kevlar, Tvoron, Spector and more.

The technical idea of ​​the body armor designed by Xu Yun this time is not complicated. To put it bluntly, there is an extremely simple but not simple formula:

Silk + ceramics.

The easy part of it all lies in the silk.

It has no technical content, and uses the principle of silk armor.

This thing has existed in the East since ancient times, but most of the customers of silk armor in later generations are only two groups:

One is armor collectors.

The second is sexy lingerie lovers and just because.

As for the easy part.

Of course it is ceramic.

well known.

Ceramic pieces by themselves cannot be used as body armor.

Because such a large piece of ceramics is too heavy, and they are hard and inconvenient to move.

Wearing such a suit, it is basically difficult to do complete movements.

However.

Ceramics can be used as a material for bulletproof plates, and they are mainly aimed at rifle bullets.

Corresponding to NIJ level III of the NIJ standard across the sea and above NIJ level IV.

It is a composite material composed of ceramics + bulletproof fibers, and the effect is relatively good even in later generations.

Because the hardness of ceramics is high, and its specific gravity is much lower than that of bulletproof steel.

When faced with shooting.

The ceramic will crush the projectile by virtue of its hardness, turning it into several projectiles with smaller mass, and then use the fragmentation of the ceramic to further reduce its kinetic energy.

Then the bulletproof fiberboard behind the ceramic receives these less threatening fragments to achieve a defensive effect.

This bulletproof fiber is the aforementioned silk.

Of course.

This type of ceramics in later generations is not ordinary ceramics, but multi-curved cermets sprayed with polyurea coating on the surface.

What was this thing doing in 1850?

Seeing this, the clever Zhong Suo Zhou must have remembered it.

That's right!

In the cathode ray experiment, Xu Yun once gave a prop that can convert electrical signals into acoustic signals——

Piezoelectric Ceramics. (Chapter 303)

After piezoelectric ceramics are polarized, the electric domains will align along the direction of the electric field.

At this time, as long as some metal is added, the characteristics of the beggar's version of bulletproof ceramics can be achieved.

Grass snake gray line, foreshadowing thousands of miles.JPG.

With piezoelectric ceramics and silk, a simple version of body armor was born.

This DIY version of piezoceramic body armor can stably defend against 7.62mm half-power rifle bullets in later generations without even hurting ribs, but it cannot prevent full-power bullets. (Youtube has a video)

However, although the 7.62mm bomb is standard in later generations, it was in 1851.

The bullets used in the Minie rifle are called Minie bullets, sometimes called Minie bullets because of transliteration problems, which are a kind of bare lead bullets.

The charge of this bullet is very small, and the lethality lies in the initial kinetic energy, so there are three ranges of power:

One is within 10 meters, the power of Minie bullets can be compared with the full power of 7.62mm rifle bullets.

The second is 10-25 meters, which is equivalent to a half-power bullet.

But beyond 25 meters, its power will show an interval decline-because ballistics is too primitive these days.

In the case of long distance.

Unless he was headshot or hit an organ like the Kennedy earlier, he would basically not die immediately.

Of course.

When the breech-loading gun technology appears, the power of the Minie bullets will be greatly enhanced.

Then Xu Yun took out a steel helmet from his backpack, which weighed five or six catties.

The performance of the steel helmets of later generations is more complicated. In fact, this thing is not to defend against bullets, but to avoid stray bullets or fragments.

However, the 1851 muzzle-loading gun has a limited rate of fire, so it can barely be called a "bulletproof helmet" if it is not shot in the face.

A body armor and this steel helmet are enough for Xu Yun to face the enemy head-on.

While Xu Yun put on his body armor.

Bourne, who was leaning against the only front window that was not closed, raised his head slightly, and glanced outside:

"Attention, the enemy is only ten meters away from the gate!"

talking.

Bourne raised the bayonet in his hand and made a defensive gesture.

Dozens of seconds passed.

Ka Ka Ka——

The sound of military boots gradually came from outside the door.

It is not difficult to judge from the interval of stride frequency, and the other party is obviously quite cautious.

Bang——

Bang——

Bang——

After a few seconds.

Three gunshots sounded suddenly outside the door.

Three holes soon appeared at the gate, but the bullets that rushed into the gate were quickly blocked by barriers.

At the same time, three gunshots sounded.

"ah!!!!"

An aristocratic lady Xu Yun didn't know suddenly screamed, and threw the book in her hand towards the small door that hadn't been reopened.

Snapped--

The book hit the small door, and there was a muffled sound.

Bourne frowned when he saw this, and gave the woman a dissatisfied look:

"idiot!"

At this time, it is obviously in the stage of probing. The enemy actually does not know how many people are in the auditorium or what their actual combat strength is.

At this time, if you can delay for one more minute, you will have more chances of winning.

Now that noble woman threw the 'weapon' first, isn't she telling the people in the auditorium opposite that people are flustered like a frightened bird?

as expected.

After the noblewoman threw the book.

The pace outside the house is a little faster, and there are some communication sounds undisguised:

"Здесьоченьволнуется!"

"прямов!!!"

"Sukka is not listed!!"

The assailants made no attempt to persuade them to surrender, but simply wanted to kill everyone in the house.

Prince Albert didn't shout out the words "I'll give you double what you charged" like the dignitaries that Ben assassinated in the storybook.

From the indiscriminate killings of the attackers at the beginning and their accents, it can be seen that there is no verbal compromise in tonight's battle, and there is no retreat.

After a while.

bang bang bang—

There was a loud knock on the door.

After all, from the perspective of the attacker, the entire door in front of him is closed at this time.

They don't realize that the barriers for wickets and gates are actually different.

But soon.

The attackers tried to get to the wicket.

"Report! There is a problem with the syllable here! The defense seems to be weak!"

thump thump——

There was another knocking sound outside the door, as the assailant made sure of the thickness of the barrier behind the door.

After a few seconds.

boom--

bang bang——

There was a gunshot and a shock from the handle of the little door.

Although the door lock is still as stable as before, there are gaps in the surrounding wooden blocks.

Students who have kicked the door of the firewood room should know it.

When there is a crack in a wooden door, even if it is still locked, the difficulty of brute force cracking has dropped by an unknown number of levels.

soon.

There was a knock on the door outside the house.

The atmosphere in the auditorium became tense again.

But Bourne and the others didn't wait, they saw him gently move to the side of the small door, aimed at the gap, and stabbed the bayonet out fiercely.

He quickly withdrew the bayonet without giving the opponent time to react.

They were pulled back and fell to the ground together, and there was a little bright red and a scream from outside the house:

"Suka Bulie! My hand, my arm was stabbed!"

Although it is not known whether Byrne stabbed the opponent's gunman.

But since he was injured, the opponent's combat ability will be affected to some extent.

Hearing the angry curses outside, Bourne raised a smile at the corner of his mouth.

Being able to add some obstruction to the enemy at this time, at least it can relieve the mood.

But soon.

There was a rustling sound in his ear, which sounded like

Straw burning?

"not good!!!"

As one of the strongest individual soldiers of this era, Bourne is familiar with this voice to the bone.

His expression changed instantly, and he threw down the subordinates around him, and at the same time shouted to Prince Albert:

"Damn it, what they ignited was a thunderbolt tube! Your Highness, the Grenadiers and the Coldstream Guards are both guilty."

boom--

Bourne didn't finish his sentence.

There was a huge explosion outside the house, and the door and the wall were blown to pieces.

The smoke and dust billowed at the entrance, and Bourne and others didn't know what to do.

See this situation.

Prince Albert's heart sank immediately.

One of the things he was most worried about really happened:

Not only did the Coldstream Guards have spies in the Royal Division, but the Grenadier troops also had a big problem!

And the grenadier unit has a ghost, which means that the opponent is likely to have.

High explosive gunpowder!

gunpowder.

It is one of the four great inventions that China has always been proud of.

Later generations generally believe that the earliest records of gunpowder in China appeared in the "Wu Jing Zong Yao" compiled by Zeng Gongliang in the Northern Song Dynasty.

There are three gunpowder formulas recorded in writing, and one is excerpted here:

"Tribulus fireball and its gunpowder method: artillery gunpowder method: Jinzhou sulfur... Swirl and evenly, wrap the clothes with five layers of paper, bind it with hemp, let alone apply it with molten turpentine, and fire it with a cannon." (Some other things are omitted. thing)

These gunpowder were finally introduced to Europe by the Arabs in the 13th century, and developed rapidly.

Like the earliest British grenadiers, what they threw was clay pots filled with gunpowder, which was conceptually equivalent to primitive grenades.

But when it comes to high-explosive gunpowder, which is a level higher than gunpowder, everyone should think of another name in their minds:

nobel.

Here is a possible misunderstanding:

The inventor of TNT explosives is not Nobel, but Wilberland.

Nobel invented colloidal dynamite, also known as nitroglycerin dynamite.

Its preparation method is... Keke, I can't say this.

At the same time, Nobel also invented the detonator-note, it is a detonator, and Bourne is talking about a detonator.

Thunder mercury appeared much earlier than detonators, and it was successfully synthesized by an English priest, Forsyth, as early as 1807—you read that right, a priest.

It is a white or gray crystal, which is the earliest explosive used by humans, and has high sensitivity to flames, needles and impacts.

Therefore, in the early days of its invention, it was widely used in percussion guns.

For example, there is thunder mercury in the Minie rifle at the scene.

However, in 1838, after T. J. Pelouz first discovered that cotton soaked in nitric acid could explode, Britain produced a special weapon:

Thunder mercury tube.

This is a very contemporary product.

To put it bluntly, it is somewhat similar to BB players and DVDs in the early 21st century, which have their own characteristics but appear and disappear quickly.

The combination of thunderbolt tubes, cotton, lead wires, and metal rings became the exclusive weapon of British grenadiers around 1850, and was specially used for tackling tough situations.

This is why Bourne immediately judged that there was a ghost in the grenadier guards after hearing the sound of the lead wire.

The appearance of the thunderbolt tube also represents another thing:

The defense system laid down by Prince Albert before has lost its meaning now.

What they had to face next was the direct attack of fifty enemies armed with Minie rifles.

Although strictly speaking, even if all the doors of the auditorium are blown open, it is impossible for fifty enemies to enter at the same time.

But when the portal has been opened, it is meaningless to be more specific about the number of people entering.

If you change to a smaller place.

The attackers could even set up guns outside and arrange for some people to throw grenades directly inside, slowly grinding the people inside to death.

Fortunately, the size of this auditorium is still large enough. With limited time, the assailant obviously couldn't do this kind of thing.

After all, the 'grenade' these days is relatively primitive, and the upper limit of a grenadier is only five to seven.

The attacker sneaked in again tonight, and unless he was carrying Doraemon's space bag, he could never have enough projectiles.

But even if this worst-case scenario doesn't happen, what Prince Albert faces is still a terrible life-and-death crisis.

His eyes were fixed on the smoke and dust at the gate, and he clenched the saber in his hand again, and there was even a gleam in his eyes.

dead business.

Except for Charles I in British history, the only monarch who was assassinated in office was Edmund Ironside.

Could it be that he will become the second sad and unlucky person now?

But then again.

Compared with the Edmund II who was stabbed to death by the Vikings hiding under the latrine, his own death method should not be so 'anal fissure'.

clatter——

Just when Prince Albert was in a daze, the sound of heavy stones falling suddenly came from the entrance.

It is clear.

This is someone pushing away some walls that have been blasted, preparing to open up a more open space.

A few more seconds passed.

Bang——

Several bullets were shot out of the smoke and dust, but due to the problem of sight, they still only hit the table, but it still caused a panic.

See this situation.

A flash of determination flashed in the eyes of Prince Albert, whose military literacy was far beyond ordinary people, and said to the surrounding people:

"Everyone, the gate has collapsed, sticking to it will only lead to death!"

"Now our only hope is to drag the attackers into close combat, preventing them from using their firearms!"

"All young and strong obey orders, turn off the lights immediately while there is still dust blocking the view at the door!"

"Migne gunners shoot immediately, after the guards are in front, everyone rush out with me!"

finished.

He turned his head to look at the two shooting points, and ordered:

"Shoot! Fire all!"

Bang——

Bang——

Bang——

Bang——

Bang——

Five Minie rifles fired quickly.

"ah!"

"Careful! Punamifu!"

"My feet!"

Five bullets hit two people.

This round of shooting suppression slightly slowed down the enemy's actions, but after the shooting, there was a reloading period of nearly thirty seconds.

at the same time.

The guard standing by the switch quickly turned off the light source, and the room was instantly dark.

Upon seeing this, Prince Albert suddenly stood up and shouted to the crowd:

"Life and death are at stake! Everyone follow me—"

As a result, the last word was not finished yet.

A vaguely familiar figure wearing a steel helmet sprang out from beside him, rushing towards everyone as if reincarnated.

Visible by the few lights that shone in from outside the auditorium.

This figure vaguely held a certain object in its hand, and when it came near the gate, it quickly hid by a wall that hadn't been blasted open.

Then

In Prince Albert's ears, he heard a rhythmic combo.

Da da da--

Becky Smirnov, 34 years old, 2.05 meters tall, captain of the Tsarist Russian Army.

He was also the first commander of the night raid team.

not long ago.

The night attack team headed by Becky Smirnoff has a total of 74 members. With the cooperation of insiders, they successfully lurked to the experiment site.

They lay in ambush behind a pre-marked area, dormant and waiting.

The field of vision in this area is hidden, and the patrol personnel are also their own people.

Therefore, Smirnov and others lurked for several hours without being discovered.

Then when the experiment was coming to an end and everyone was most relaxed.

Smirnov launched the attack.

Smirnov's first shot was actually aimed at Prince Albert, but the distance was too far, and the shot missed the target.

Instead, he shot the happy-looking middle-aged man next to Prince Albert.

Fortunately, this kind of error is not a big problem.

The reason why they came so many people tonight was that they were ready for a frontal attack—even if Prince Albert was killed by one blow, they would still start a large-scale massacre.

in short.

The more people killed, the more chaos the better.

anyway

In the guards in the town of Cambridge, there are also their people who will delay time

as expected.

As predicted in their battle plan, Prince Albert did not flee to the open space foolishly, but retreated into the auditorium.

The assassination turned into a fortification.

This is the last situation Smirnov wants to see, but it is still not difficult.

after all

For the success of this attack, the forces behind them used almost all the cards in their hands.

For example, someone pushed the flames and invited many imperial dignitaries who were not interested or hesitated.

Someone has ambushed and created the perfect entry for them.

Others supported supplies. In addition to the Minie rifle, there were top-secret weapons of the British army such as mine pump tubes.

Ghost in all staff.jpg.

This moment.

Looking at the door of the auditorium that had been blown open in front of him, the corners of Becky Smirnov's mouth curled up slightly:

"Lieutenant Harrington, prepare to attack."

Harrington in Becky Smirnoff's mouth was a Scottish soldier with a thick beard. Hearing the words, there was a trace of vigilance in his eyes, and he suggested:

"Captain Smirnov, just to be on the safe side, do we need to try again?"

"After all, there are still guns in the auditorium"

"Anyway, we have plenty of time, so we can observe the situation before rushing in."

"Don't worry too much, Lieutenant Harrington, those are just a few broken guns!"

Becky Smirnov waved his hand and pointed to the subordinates behind him with his thumb:

"Fifty Minie rifles against five weapons of the same model. I have the advantage. Tell me how to lose if the barrel is blocked in the face?"

As he spoke, he put the Mines rifle in front of him, and waved in other directions:

"The windows in the auditorium are too small, and it is impossible for the people inside to escape through the windows. The people under martial law around me immediately gathered around me, and everyone rushed in together!"

"Gun in hand, follow me!"

Military orders are like a mountain, facing the instructions of his immediate superiors, Harrington can only obediently follow them.

rustle——

The sound of military boots walking on the snow came, and all members of the night attack team gathered outside the gate.

Just when Becky Smirnoff was about to give the order to rush into the house.

Under the illumination of the external lights of the auditorium.

Out of the corner of his eye, he suddenly faintly saw the appearance in the corner of the main entrance.

A long, dark tube.

Then the next second.

Da da da--

With a very rhythmic sound sounded.

Harrington next to Smirnov screamed helplessly, and fell on his back.

Then without waiting for Smirnov to react.

The subordinates around him seemed to be performing a song and dance drama, and people kept falling down, and the venue was full of wailing.

Immediately afterwards.

The clicking sound paused for two seconds, and two clicking sounds came clearly from Smirnov's ears.

Then

Da da da--

The second round of blows sounded, and several people fell down in response.

Since the scene in front of him had surpassed Smirnov's cognition, he didn't react until then, and suddenly picked up the gun and shot towards the wall:

"Enemy attack! Behind the left wall!"

Snapped--

Snapped--

Snapped--

Several shots sounded.

In addition to Smirnov, members of the night attack team also counterattacked.

When Smirnov saw this, he immediately looked happy—he must have at least four bullets hitting the body of the secret attacker!

However, in the next second, his expression froze on his face.

I saw that the person behind the wall seemed not to be affected in the slightest, and clicked something again.

Da da da--

The crisp combo sound rang out for the third time.

this time.

Becky Smirnov, who was standing there in a daze, suddenly felt a pain in his chest.

Less than half a second.

There was a sense of dizziness in his mind, and his vision gradually began to blur.

click -

He let go of his fingers, and the Minie rifle slipped from his hand and fell to the ground.

At the same time, the whole person lost support, first his knees, and then the whole person collapsed to the ground.

Just when Smirnov's residual consciousness began to dissipate.

He raised his head with the last bit of strength and looked around.

I saw three rounds of shooting.

At least 70% of the subordinates who were recruited by him to block the door fell to the ground.

Or died of exhaustion, or the body was shot and wailed endlessly.

The rest either hid behind bunkers, or simply fled the scene.

at the end of life.

A thought suddenly popped up in Smirnov's mind:

Who can tell him what happened?

What about your teammates? ? ?

at the same time.

In the auditorium.

Xu Yun shot a few more times towards the door.

If it is said that Mao Xiong, Da Mao, and Huaxia belong to a complex situation with both grievances and grievances, it needs to be discussed comprehensively in light of the international situation and positions.

So in history, Tsarist Russia's treatment of China was pure evil.

Therefore, now that he is fighting hand punches (?), Xu Yun seems to have no pressure psychologically.

After finishing a clip.

Xu Yun looked out the window.

After confirming that most of the enemies had been wiped out, he looked back at the people who were still in a daze.

This moment.

Everyone has the same expression:

O.O?

Even Albert, the uncrowned king of the British Empire, looked dull and funny.

so many enemies.

That's it?

Then, without waiting for Prince Albert to speak, Xu Yun opened his mask and asked him directly:

"Your Majesty, there are still some enemies outside the door that have not been eliminated. Can the guards solve them?"

Prince Albert was slightly taken aback when he heard the words, and subconsciously said:

"sure."

Although the personal guards are not equipped with live ammunition, this does not mean that their military quality is not good.

Quite the opposite.

As the pro-army that may play in the war stage, all the pro-guards' marksmanship is the best, and there is no such thing as an interstellar player.

Right now, apart from Bourne and others whose life and death are unknown, the number of personal guards around Prince Albert is about 20 or so.

Not to mention that some nobles also have good marksmanship.

And the attacker

Due to a certain captain's coquettish operation, all the members of the night raid gathered at the entrance of the auditorium, and made a living target for Xu Yun.

Three rounds shot down.

More than 70% of the attackers were dead or lost their combat effectiveness, and the rest were like frightened birds, and some simply dropped their guns and ran away.

If you can get the Minie rifles scattered outside the house.

Even if Xu Yun didn't make any further moves, the situation on the scene wouldn't repeat itself any more -- at worst, Albert would just huddle in this auditorium and wait for reinforcements.

See this situation.

Xu Yun nodded slightly, indicating that he understood.

Then he looked at Mai and the others.

As the return approached, he no longer deliberately followed some etiquette.

I saw his eyes quickly swept over Mai, Lao Tang, Gauss, Faraday, Riemann and others.

Regardless of whether what he does next has any results, this time will be a real farewell.

According to Xu Yun's original plan.

He also planned to say goodbye to these acquaintances in the remaining four hours.

But now it seems.

He doesn't have so many opportunities to be hypocritical.

Because in the remaining time, he still has to find two people.

No.

Precisely

It should be three people.
