Into Unscientific

This moment.

By the foot of the mountain.

Looking at the F-500 central axis drone hovering above his head, Xu Yun couldn't help but have a subtle expression.

Although this mountain peak is only over 300 meters high, it is not an easy task to cover its surface with a layer of ice slag.

To know.

In general.

Except for the multi-peaked mountains with a relatively large area like Yuelu Mountain, a 300-meter mountain peak covers an area of ​​about 2 to 3 square kilometers, and its body surface area is even larger.

At present, the bucket load of a fire-fighting helicopter is generally about 3-5 tons, and the maximum load is only 8 tons.

Of course.

The Xichang launch base is different from ordinary institutions. The helicopters used must be like the F-500 central axis drone, which has been magically modified in terms of load.

But no matter how you change it, it will take at least one or two hours to cover the surface of the mountain with ice slag.

Given the personalities and status of Li Hua and Ge Tongyou, it is obviously impossible to engage in such boring things when they are full, and they must have their goals.

And speaking of the word ice.

Most people's minds must be that JackeyLove is wrong, it is a source of water such as rivers, seas and rivers.

After all, there is water to have ice.

At the same time, the ice slag on the mountain is a little thinner than the standard ice surface in terms of thickness.

However, after increasing the accumulation of the soil layer inside the mountain, it is barely comparable to the ice layer with a thickness of about one to three meters.

in this case.

Li Hua asked the gravity gradiometer to detect things inside the mountain

Almost in an instant.

A word popped up in Xu Yun's mind:

nuclear submarine.

That's right.

nuclear submarine.

Probably around March 21, many people must have seen a piece of news:

Maoxiong's three strategic missile nuclear submarines completed a simultaneous ice-breaking and floating military exercise in the North Pole, with a thickness of 1.5 meters.

This exercise can be described as a magnitude 10 earthquake among fans in the military circle. Even the people on the other side of the sea were so frightened that they almost peed out—this sentence is not an exaggeration, but really almost peed out.

But many passers-by have been wondering why:

Isn't it just that the nuclear submarine floated up in the North Pole and broke through a layer of ice? How did it shock the West?

What is so great about this?

This involves the concept of a second nuclear strike capability.

The so-called second nuclear strike capability means that you are wiped out by a wave of nuclear bombs preemptively by the enemy. Almost all nuclear bomb launch facilities have been destroyed, and everyone thinks you are finished.

But at this time, you still have a hidden trump card that you can use.

For example, nuclear submarines hidden in the deep sea, such as strategic bombers cruising in the sky, etc.

None of these things have been destroyed in the first nuclear strike and can retaliate against the enemy with a nuclear strike.

So strategically speaking.

As long as you have the capability of a second nuclear strike, the enemy will not dare to launch a nuclear strike on you at will, because you will suffer from it if you do not die.

If you are not dealt with in the first wave, you will face your merciless revenge.

Among the second nuclear strike force, the most important is undoubtedly the nuclear submarine-because the strategic bomber can actually be locked.

In big countries like Rabbit, Maoxiong, and across the sea, nuclear submarines are on duty all year round, and there are several nuclear submarines lurking in the depths of the ocean at any time.

They communicate through long-wave radio stations, and the submarine receives radio signals from the command at regular intervals.

If there is no news from this band one day.

That would mean a nuclear war broke out and the headquarters was blown up.

At that time, the submarine will wipe out all the nuclear missiles in one go, and then the whole world will be nuclear-leveled-of course, it will not be so exaggerated in reality, and a second confirmation will be carried out before the nuclear bombs are fired.

The radio waves used to contact nuclear submarines are all public frequency bands. For example, many netizens have used radios to receive radio waves sent by Mao Xiong to nuclear submarines.

Sometimes it is a short piece of Russian, sometimes it is a short piece of electronic rhythm, and sometimes it is a short piece of electrical noise.

In short, they are all radio waves without rules and meaning, and only people on nuclear submarines can distinguish them.

But on the other hand.

Nuclear submarines also have weaknesses - in modern warfare, discovery means destruction.

The nuclear submarines hiding in the deep sea are powerful, but the anti-submarine technology of various countries is also very strong.

Up to now, the five rogues can basically scan 99% of the nuclear submarines in the sea area.

Apart from

Arctic.

That's right.

Arctic.

The Arctic is a natural hidden field for nuclear submarines, and its thick ice cover can block the detection of all modern technologies.

The large area of ​​ice makes up for almost all the shortcomings of nuclear submarines, making nuclear submarines the perfect god of war.

At the same time, the density of water is much greater than that of air, and seawater has a strong absorption effect on electromagnetic wave energy.

Therefore, conventional electromagnetic waves are almost impassable in sea water.

To detect nuclear submarines, only sonar detection can be used.

But whether it is anti-submarine aircraft throwing a large number of sonar beacons for detection, or surface warships using shipboard sonar systems for detection, the means are completely abolished in front of the Arctic ice sheet:

The sonar beacons dropped by anti-submarine aircraft cannot even enter the water, and the warships simply cannot enter the water.

Only the submarine itself can enter the North Pole.

Ordinary diesel submarines need to consume a lot of oxygen for diesel fuel to burn when moving forward, but the entire North Pole is covered by ice.

in other words.

If an ordinary diesel submarine dares to enter under the Arctic ice sheet, it will be suffocated alive under the ice layer, and the engine will be turned off directly.

The only nuclear submarine that does not need oxygen to drive the engine only needs to provide the oxygen needed by the crew, so it can operate under the Arctic ice for a long time.

In the huge Arctic range, if the nuclear submarine does not actively turn on the sonar system on a large scale, it will be difficult to find the enemy submarine.

But which nuclear submarine dares to take the initiative to open a wide range of sonar detection?

If you turn on sonar in a wide range, it is not easy for you to find hostile submarines in a silent state.

But the hostile submarine can accurately find your position at the first time, and then you will be killed immediately, with a torpedo.

Two hunters with guns held their breath in the darkness, and one of them foolishly lit a torch to try to find each other.

If you don't die, that's called evil.

When neither side turns on sonar active detection, it is difficult for nuclear submarines to find each other even if they face each other.

For example in 2009.

John Bull's "Avantgarde" nuclear submarine and Gaul's "Triumph" nuclear submarine collided with each other during cruise, but they didn't know what they collided with after the collision.

Therefore, with the current human technology, there is no way to deal with the nuclear submarines hidden under the ice.

In a sense.

It can be considered that the nuclear submarine under the Arctic ice is equivalent to the existence of immortality, which cannot be destroyed by any means.

And right now, if this gravity gradiometer can detect the situation inside the mountain in detail under the obstruction of the accumulation of ice slag and the mountain

No, even if only part of the intelligence was detected

Then the fun will be great.

that's all.

In the eyes of everyone's anticipation and tension.

ten minutes later.

click click click——

There was another sound from the printer, and a stack of documents that was much thicker than the previous two times appeared at the exit of the device.

Zhang Han didn't have time to read the contents of the report, so he quickly put them away and took them to Xu Yun's side:

"Dr. Xu, the results are out."

"Thank you, Miss Zhang."

Xu Yun thanked Zhang Han, took the report, trembled a few times like an old doctor looking at a CT film, and began to check it carefully.

It is different from the previous detection of underground pipes and carriages.

It can be clearly seen from the data that the measurement results this time are indeed relatively 'fuzzy'.

At least it is difficult for Xu Yun to judge the results intuitively with the naked eye - of course, this is also related to Xu Yun's lack of deep understanding of the gradient database.

So he took the initiative to come to the console and retrieved a copy of the gradient database.

This gradient database is one of the relatively public data information databases in China. As long as it is a doctoral student in a C9 university, it can be consulted, and the threshold is very low.

clap clap -

Xu Yun quickly pressed a few keys, and a list of gradient databases soon appeared on the screen in front of him.

"B2654"

"K2528"

Facing the screen like this, he began to check the detection results.

after awhile.

Seeing that Xu Yun hadn't opened his mouth to speak, Tongyou Ge beside him couldn't help it:

"Dr. Xu, what happened to the test results?"

Hearing this, Xu Yun came back to his senses, stretched out his hand and lightly adjusted his glasses, and said with a little apology:

"I'm sorry, Professor Ge was too engrossed in looking at the data just now. Well, let me report the specific results to you. You can see that it is different from the actual situation."

"By the way, can these data be made public here?"

Ge Tongyou nodded slightly, pointed to the mountain behind him, and said:

"Of course, this mountain can be regarded as a public material reserve. Before you came, there were a small number of things that were not convenient for the outside world."

"However, these things have been transferred out as early as yesterday, and those that can be used as 'examination questions' are very ordinary materials or equipment, don't worry."

Xu Yun breathed a sigh of relief, pondered for a moment, and continued:

"Then I don't worry about it. First of all, according to our scanning results, the orientation is according to... Well, let's start reporting from the south entrance inward."

"According to the gradient report, we have detected a gradient difference in the meat on both sides of the entrance, and we can clearly confirm that the large category is reserved meat."

"However, I can't tell whether it's pork, beef or mutton. After all, it's not a perspective instrument. The possibility of Kunkun meat can only be ruled out from the superimposed density."

After listening to this sentence.

Ge Tongyou glanced at Li Hua secretly, his face remained unchanged, but his hands behind him quietly clenched a little:

"continue."

The results reported by Xu Yun are consistent with what he knows, but the entrance of the reserve is relatively outside, and the upper soil layer is the least according to the profile, and the results that can be detected do not fully explain anything.

Xu Yun obviously understood this truth, so he continued:

"The area where the meat is stored has been covered to about ten meters inside the entrance. According to the detection feedback, the gradient difference of the main objects has obvious metal and skeleton distribution. It seems that they should be tents and other materials."

"At the same time, some conventional medicines, bandages, alcohol, and some mahjong tables were also detected around the tent."

Hear the word mahjong table.

A slightly subtle expression appeared on the faces of the surrounding people at the same time.

According to the type of items described by Xu Yun.

The second area is obviously a variety of disaster relief items, mixed with a mahjong table

Well, it's Sichuan province.

Then Xu Yun looked up at Ge Tongyou, and found that the other party still had no expression, so he continued:

"Further inside the tent, we come to the real interior of the mountain, which is the central axis of the benchmark mountain. After deducting the internal space, the vertical rock formation height reaches 134 meters."

"We detected cement and some Type 67 wooden-handled happy sticks in this area, plus some items whose identities are still unknown. They should be effervescent tablets or water purification tablets?"

"also."

Said here.

Xu Yun paused again, and continued:

"We also detected the dismantled hangar roof alloy plate of a ship, which should be one of the 22 056 frigates that were launched in 2013 and decommissioned in 2018." (Just in case I delayed the time by a year, In fact, 12 were launched and 17 were retired.)

Xu Yun didn't hesitate much when he said this, after all, this matter has nothing to do with confidentiality:

The reason for the collective retirement of the 056 frigates is because other more advanced ships have launched into the sea, which has nothing to do with confidentiality.

Actually.

The Jiujiang ship, which was decommissioned on June 12, 2018, was open to JJ citizens for free in 2019.

At present, some of these decommissioned warships are open to the public for viewing, and some important parts are removed and sent to the hinterland of the third line along the Yangtze River.

For example, among the invalid reserve materials publicly destroyed in Chengdu in 2011, there was a set of antenna arrays decommissioned in 2004. At that time, the antenna arrays were so old that even small African countries could not look down on them, so they were melted down and destroyed.

At present, the important parts of these decommissioned ships are basically stored in the third-line area.

After reporting these data.

Xu Yun put down the report and looked up at Ge Tongyou and Li Hua.

at first.

Li Hua and Ge Tongyou were still tense, looking very serious.

But not long.

The corner of Ge Tongyou's mouth couldn't help but curled up slightly, and the curve became bigger and bigger, and finally...

Turned into a bright smile:

"Hahaha"

With Ge Tongyou's laughter sounded.

Li Hua's expression couldn't hold back anymore, his cheeks puffed up heavily, and with a puff, he also let out a hearty laugh.

Then Li Hua grabbed Xu Yun's shoulders and patted Xu Yun's back vigorously:

"Xiao Xu, Xiao Xu, you really made a great contribution this time!"

"This time we used the shielding effect composed of ice slag and the mountain. Theoretically, the target is an ice surface with a thickness of 1 to 3.5 meters. The entrance is the thinnest and the center of the mountain is the thickest."

"Even if there is a cough on the top, Deputy Worker Huang, whose hometown is Shantou, estimated in advance that he could only detect about 1.2 meters before reaching the top."

"I didn't expect that you gave us a big surprise this time!"

Talking and talking.

Li Hua's expression even showed a bit of gnashing of teeth:

"3.5 meters, Xiao Xu, do you know what this concept is?"

"The average thickness of glaciers in the entire Arctic is only 2 to 4 meters!"

"That is to say, when we complete the official upgrade, none of the black fishes in the North Pole will be able to escape! Not one of them will be able to escape!"

As Li Hua said.

Unlike the Antarctic's average ice of 1,700 meters, the North Pole's ice is only 2-4 meters thick.

Right now, this beggar's version of the gravity gradiometer can break through the limit when it is sloppy assembled, and the accuracy can reach 3.5 meters.

Then after the improvement of the military industry end, there is no pressure at all to break through to 4.5 to 5 meters.

Indeed.

Taking the current international situation that is still peaceful on the surface, even if the rabbit finds nuclear submarines on the opposite side of the sea or from other countries under the North Pole, it cannot destroy them remotely.

But a lot of things don't mean that if you don't use them now, they lose their meaning. Anyone with a discerning eye can see the strategic value of this thing.

At the same time more importantly.

Although the core material of this gravity gradiometer is Pangu particles that are capable of being produced by various countries today.

However, in terms of specific measurement modules and structural design, there are strong research and development barriers-if Xu Yun does not have the blueprint rewarded by the halo, completing these two links is also difficult.

Therefore, unless it is opened across the sea, there is no need to worry about other countries or institutions mastering this research and development technology in the short term.

Feeling the shoulder tightly pinched by Li Hua, Xu Yun was also very excited.

However, as a developer, he is very clear that the gravity gradiometer can land this time, not only because of his own credit:

"Li Gong, this incident is indeed worthy of celebration, but there is one sentence you said a bit too much."

"This time we were able to achieve results far beyond my own credit. Professor Ge's balance module and Professor Huang's structural diagram also played a very important role."

"Without everyone's concerted efforts, I would be far from being able to succeed alone."

Li Hua glanced at him when he heard the words, and at the same time as he nodded, a trace of relief appeared on his face.

He was gratified not because Xu Yun didn't take credit, but because Xu Yun could still maintain a sober, or pure heart in this situation.

be honest.

This is a very rare quality.

Then he shook Xu Yun's shoulder vigorously, motioning him not to worry about others, and explained:

"Don't worry, Xiao Xu, we have a lot more money now, and we won't be unable to get material rewards for many contributions like before."

"For example, I can tell you right now that Lao Ge will go through our internal award process. As for Professor Huang?"

Seeing that Li Hua seemed to be rewarding herself, Huang Yuting at the side quickly shook her hand and interrupted:

"Li Gong, I don't bother with bases or national rewards here - I am already satisfied with seeing the first test of the gravity gradiometer today."

"I have only one request personally, that is, when Yongling is being excavated, I can be allowed to go to the site to observe and emulate in person."

Hear her words.

Li Hua turned his head and looked at Ge Tongyou, and suddenly Qiqi showed a playful smile:

"Little Huang, are you sure you don't want this reward?"

Huang Yuting was taken aback for a moment.

She noticed the change in the address of the two of Li Hua - except for the phrase "little girl" when they first met, they all called themselves Professor Huang in other periods of time.

Then Li Hua turned around and said to those who didn't know why:

"Everyone come with me first."

After speaking, he greeted everyone and walked towards another direction at the foot of the mountain.

After walking about two hundred meters.

A group of people stopped in front of a warehouse.

Li Hua stepped forward to enter a password and verified his fingerprints, and the warehouse was quickly opened, revealing the open space inside.

Li Hua pointed to the inside again:

"come in."

Everyone obediently followed in.

The aisle of the warehouse is 30 to 40 meters long. Taking the opportunity to enter the warehouse, Xu Yun also saw some details that the gravity gradiometer could not confirm:

For example, the piece of meat that was scanned before was pork, which was hard and steaming. It looked like it was temporarily moved from some freezer for this experiment.

Another example is that the mahjong table does exist, and tmd is an automatic model

Then under the guidance of Li Hua.

A group of people quickly came to the innermost part of the warehouse, which is also the very center of the mountain.

At this time, some special cement and packaged wooden boxes were placed here, and the boxes were undoubtedly Type 67 happy sticks.

But compared to these two gadgets, what really catches the attention is an object on the side of the cement:

This is a tall object wrapped in black cloth, it looks like it is three or four meters high, and the surface is 'convex and convex'.

It is clear.

This is the alloy plate on the hangar roof of the ship that Xu Yun and the others detected earlier.

If nothing else.

Below the curtain should be rolling doors, communication antennas, etc. - of course, the fire control radar of the anti-aircraft missile is definitely not included.

Seeing that Huang Yuting's expression was still a bit dazed, Ge Tongyou couldn't help but said:

"Little Huang, do you still remember what I said when we first met - I served in the Navy XX unit a long time ago, and the gravity gradiometer designed by Lao Huang in 2013 was installed in my old unit On the ship, the number is XXXX."

"The ship's lifespan expired in 2018, and the measurement equipment at that time was much more accurate than in 2013, so the gravity gradiometer was decommissioned along with the ship."

Huang Yuting was taken aback again, and then her eyes widened, with an expression of disbelief in her eyes:

"Professor Ge, you mean."

Ge Tongyou nodded without further explanation, pointing to a corner of the curtain and said:

"Pull it out and have a look."

Huang Yuting's heartbeat suddenly started to speed up,

Then she looked at Xu Yun, Li Hua, and Ge Tongyou.

Then he walked to the edge of the curtain with some apprehension, and twitched lightly.

Hula~

With the opening of the curtain.

A hangar roof alloy plate with a size of about 2X4 appeared in front of her.

Apart from some other small parts on this alloy plate on the roof of the hangar, the most conspicuous thing is a black instrument more than one meter high.

And Huang Yuting saw the instrument at the moment.

His vision became a little blurred.

She walked gently to the side of the instrument, skillfully touched the side of the instrument, and her fingertips touched a small screw cap.

It was the summer of 2013, and the instrument was completed in the same month as her master's graduation.

At that time, Huang Danian specially applied for a procedure, and brought Huang Yuting into the Beihai Fleet's R\u0026D center, and Huang Yuting screwed on the last screw of this instrument by herself.

This is also the first high-sensitivity shipboard gravity gradiometer equipped by the Navy.

The position of the screw. Impressively, it was right where she was touching it.

Fast forward ten years now.

Unexpectedly, she saw this instrument again in Xichang today.

And just as Huang Yuting was filled with emotions, Ge Tongyou's voice sounded from her ears again:

"Xiao Huang, there is something I want to tell you."

"Considering that the current accuracy of this gravity gradiometer is no longer worthy of secrecy, after discussion and approval from above, the base has decided to terminate its reserve mission and return it to you."

"In addition, the base is also preparing to sign a fixed-point project agreement with Jilin University, with an initial investment of 4 million yuan to fully support your research."

"If you have no objections, we can carry out the relevant handover after returning to the headquarters."

Ge Tongyou didn't finish his sentence.

Huang Yuting, whose eyes were already filled with tears, had a sore nose, and two hot teardrops slid down her cheeks, falling heavily on the metal shell of the instrument
