I watched Er Chuang’s short video, and everything went numb!

【Time Travel Knowledge Guide: Teach you step by step how to build a steam engine. 】

As soon as this title appeared on the giant screen.

The ancient people of all dynasties were very excited.

In particular, many emperors in the past dynasties were so excited that their eyes turned red.

They had just learned about the great uses of steam engines, and were thinking about how to make steam engines, and now they had a method of making steam engines.

What does it mean to have a pillow when you feel sleepy?

What is timely rain?

This is!

Da Qin plane.

Qin Shihuang said loudly to the officials of Qin:

"Dear friends, please read it carefully, remember it carefully, and remember the following content clearly!"

One person should record it, for fear of omitting something.

So he asked all his ministers to record it.

Moreover, on the other side, there was a group of people who were responsible for recording with pens and bamboo slips.

This was the person Qin Shihuang had arranged long ago, who was responsible for recording great things. The content in the act that he found useful.

The matter of the steam engine was too important.

In case anything was omitted, Qin Shihuang asked everyone to memorize it so that he could check for omissions and fill in the gaps when sorting it out.

In other dynasty planes, Li Shimin and others also did the same Almost similar arrangements were made

【A steam engine is a reciprocating power machine that converts the energy of steam into mechanical work.】

【The steam engine is mainly composed of cylinder, base, piston, crank connecting rod mechanism, slide valve steam distribution structure, speed regulating structure and flywheel. 】

On the giant screen, a structural diagram of a steam engine appeared, with the names of different parts marked on it.

"Quick, quick, draw it down! No mistakes allowed!"

In many planes throughout the dynasties, Qin Shihuang and other emperors sternly ordered to the painters.

This is a priceless treasure!

After having this structural diagram, the craftsmen can build it according to the diagram.

【Next, let’s take a look at the simplified steam engine principle. 】

In the giant screen high in the sky.

The structural diagram of the steam engine disappeared.

Instead, there is an animated video about the principles of steam engines.

"Not all drawn."

In the plane of the Ming Dynasty's founder, Zhu Di asked Zhu Zhanji eagerly.

He naturally handed over the matter of drawing to Zhu Zhanji, who was good at painting.

Zhu Zhanji shook his head and replied:

"It disappeared too quickly. I couldn’t finish all the drawings. I just drew a rough outline."

"Continue reading first. If that picture appears again, continue drawing immediately."

"Now draw the next content."

Zhu Di ordered Zhu Zhanji in a deep voice.

Although he was a little disappointed, Zhu Di did not blame Zhu Zhanji.

The picture in the giant screen indeed disappeared too quickly.

Zhu Zhanji can draw a rough outline, which is already very good. At this time.

Along with the narration and subtitles, a video demonstrating the working principle of the steam engine on the giant screen began to play.

【In a steam boiler, through the combustion process water boils into high-pressure steam, which passes through pipes from the left cylinder, pushing the piston to the right】

【After reaching the right side, the connecting rod will push the reversing valve to move to the left】

【After switching, high-pressure steam enters the right side of the cylinder and pushes the piston to move to the left】

【The exhaust gas on the left is discharged through the reversing valve】

【When the piston reaches the left side, the connecting rod pushes the reversing valve to the right again.】

【Repeatedly, converting the pressure of steam into reciprocating mechanical motion】

【And reciprocating motion can be easily converted into circular motion.】

【This is the most basic principle of the steam engine】

"The working principle of a steam engine is very simple, but it is not simple to build it under ancient technological conditions."

"Without modern iron smelting technology, high-pressure boilers would be a problem"

"Under ancient conditions, you can try using iron to make water boilers and cast iron to make pistons and various cylinders. The difficulty is that the diameter of the piston is slightly smaller than the diameter of the cylinder."

"The essence of the steam engine is the double-acting piston, which does work in both push and pull directions."

"If we really wanted to build a steam engine in ancient times, we would probably have to get the machine tools out."

"Without rubber, how to solve the sealing problem?"

"Reply - When Watt improved the steam engine, there was no vulcanized rubber. He seemed to have used linen soaked in oil."

"Reply - Use piston rings. Large steam engines must have piston rings."

"……"

Most ancient people in the past dynasties felt confused when looking at the video content and barrages on the giant screen.

They don't understand it at all.

However, some ancients also understood something from it.

Warring States plane.

Lu Ban looked at the giant screen and kept trying to understand the principles of steam engines in his mind.

The more he thought about it, the more he realized how powerful a steam engine was.

The plane of the Three Kingdoms.

Liu Bei asked Zhuge Liang expectantly:

"Kong Ming, do you understand? Can we build this steam engine?"

After the sun never sets in the country with the steam engine, it became a superpower that dominated the world.

If the Shu Kingdom can create a steam engine, then it will be just around the corner to bring peace to the world and restore the Han Dynasty!

Zhuge Liang was thinking while looking at the giant screen. He opened his mouth and replied:

"I roughly understand the principle of this steam engine."

"However, as later generations said, it is not easy to make it."

The giant screen shows video step-by-step instructions and step-by-step explanations. As long as someone has knowledge of mechanical manufacturing, it is not difficult to understand them generally.

"It doesn’t matter if it’s difficult, as long as you have a direction!"

"As long as you explore a little bit, you can make it sooner or later!"

Liu Bei replied in a deep voice.

The Chongzhen plane of the Ming Dynasty.

Song Yingxing looked at the giant screen while writing quickly.

At this time, the content of the giant screen gave him a great shock.

"What a genius idea!"

He exclaimed in admiration.

At the same time, he had a bold idea in his mind. He wanted to build this steam engine.

In many other dynasty planes, some people also developed steam engines after learning about the principles of the steam engine from the sky. The idea of ​​a steam engine.

Although it is not easy to make a steam engine based on the level of science and technology in ancient China.

But there are clear structural diagrams provided by the giant screen, as well as clear explanations of the operating principles, plus heroes such as Qin Shihuang, Li Shimin, Zhu Yuanzhang, Zhu Di, etc. Promote research and development at all costs.

Perhaps, the problems in the manufacturing process of steam engines will be solved one by one.

One day, ancient China will create steam engines earlier than the country where the sun never sets.

On the high-altitude giant screen.

The video is refreshed again.

This video , still related to steam engines.

The video title is:

【The design and working principle of steam trains】

【Before introducing the steam train, let me first talk about the laying of railway tracks.……】

【Let’s start with a formal introduction to the design and working principle of steam trains.】

【This is a 484 steam train, which means there are four guide wheels at the front, eight driving wheels, and four slave wheels at the back.……】

【……】

【Behind the front of the car, there is a special carriage called a tender car.……】

【……】

Among the narration and subtitles, the video on the high-altitude giant screen explains in detail the design and working principle of the steam train.

Qin Shihuang, Li Shimin, Zhu Yuanzhang, Zhu Di and other heroes all ordered people to write down this knowledge. (To read exciting novels, go to Feilu Novel Network!)

After successfully building a steam engine, they will also try to build a steam train.

……

In the giant screen high in the sky.

Video refreshes.

New video appears

【Decipher the thirty-five-year-old military secrets of the Dragon Kingdom!】

【56 years ago, 60,000 soldiers of the Dragon Kingdom mysteriously"disappeared" overnight, and a small town was wiped off the map.】

【After 35 years, the people in Longguo suddenly realized】

【Sixty thousand people spent 17 years hollowing out a huge mountain to build the world's largest artificial cave.】

【Today, I will take you to visit a place that was sealed for 35 years: the August 16th Underground Nuclear Project Site】

【This is also the only nuclear reactor currently declassified in the Dragon Kingdom. 】

Hearing this, many ancient people from all dynasties became very interested.

They stared at the giant screen intently, wondering what was so special about this military secret that had been sealed away by the Dragon Kingdom for thirty-five years.

What kind of project requires 60,000 soldiers to spend 17 years to build?

【In October 1964, after the first atomic bomb made by our country was successfully exploded in the Lop Nur area, although it had its own nuclear weapons, it also focused all the attention of Big Brother and Eagle Country on Long Country. Big Brother and Eagle Country Intensified the military threat to the Dragon Kingdom】

【The two countries declared at the time:"Once a war breaks out, they will be sure to destroy all the nuclear base facilities in the Dragon Kingdom within ten minutes.""】

【And in fact, both Big Brother and Eagle Sauce Country almost took actual action at that time. 】

Some ancients in the past dynasties thought of the video they had watched before, and the"family-changing plan" of the leader and teacher of the Dragon Kingdom that made their scalps numb.

The plane of Emperor Taizong of the Tang Dynasty.

Li Shimin sighed with emotion:[]

"The Dragon Kingdom at that time was indeed too difficult."

A neutral country that just emerged from the ruinsA country that has existed for a long time has been hostile to the only two superpowers in the world.

It’s extremely difficult just thinking about it.

But precisely because of this, Li Shimin admired the later Dragon Kingdom even more.

Being able to develop and grow independently under such difficult circumstances shows the true ability of the Dragon Kingdom.

【In this context, building a nuclear industry base with greater concealment and security has become an urgent need for the military and national defense of the Dragon Kingdom at that time.】

【This new nuclear industry base is called: 816 Nuclear Project, also known as the"Tianzi No. 1" project.】

【In the mountainous area of ​​the southwest mountain city, there is a small town called Baitao Town. This small town on the bank of Wujiang River is named"Baitao Town" because of the rapid current and white waves of Wujiang River."】

【In the 1960s, Baitao Town suddenly disappeared from the map, and its address in correspondence was only"Shancheng City Box 4513""】

【The reason for this is that Jinzi Mountain in Baitao Town is the construction site selected for the 816 Nuclear Project.】

【After determining the location, the Longguo government transferred all the local residents of Baitao Town to other places.】

【The 816 Project was undertaken by three regiments of the 54th Longguo Engineering Corps, plus more than 10,000 migrant workers and nearly 10,000 technical personnel. In the end, several people gathered together, totaling more than 60,000 people.】

【After entering the mountains, this huge team became a member of the unified code-name"8342". You must know that the team that protected the supreme leader at that time was code-named"8341", which is enough to show the importance of this matter.】

【All these 60,000 people must obey the confidentiality agreement. They will not tell their parents, their wives and children, and they will keep it secret for life.】

【On the smoky Jinzi Mountain, officers and soldiers built a chimney more than 200 meters high. In addition to its exhaust and ventilation functions, the chimney emits a large amount of water vapor to interfere with enemy reconnaissance aircraft.】

【The engineering soldiers responsible for the construction of the cave body were divided into four groups of people in company units, and they took turns charging and digging into the interior of Jinzi Mountain day and night. 】

With the narration and subtitles, a green mountain appeared on the giant screen high in the sky.

There is a tall chimney on the top of this green mountain. Other than that, there is nothing unusual about it on the surface.

But when the ancients of all dynasties heard this, they somewhat understood it.

This is about digging mountains!

The plane of Ming Taizu.

Zhu Biao said in surprise:

"Sixty thousand people dig a mountain? So what kind of shape will this mountain have to be dug into? It won't be hollowed out, right?"

"Probably not. It would be too difficult to hollow out such a huge mountain."

Zhu Yuanzhang replied

【In an era without advanced technology and equipment, soldiers could only use explosives to blast open the thick rocks, then use their hands to dig pits and plan the rocks, carry them on their shoulders, and use both hands to dig out the holes with a shovel and an iron drill. A mountain, dug out an"underground Great Wall""】

【After more than eight years of hard work by a team of more than 60,000 people, the entire Jinzi Mountain was almost hollowed out, and the 816 Nuclear Project cave was finally successfully excavated. 】

In the giant screen high in the sky.

The scene changes.

Arriving at the cave entrance of the 816 Nuclear Project

"It actually hollowed out a building？"

Ancient people of all dynasties were shocked.

They began to look forward to seeing what was inside the hollowed-out mountain.

With 60,000 people and more than eight years, it must be a huge project

【The entire base of the 816 Nuclear Project covers an area of ​​100,000 square meters. The cave is 21 kilometers long and consists of 19 large main caves. There are more than 130 road tunnels, automobile traffic, ventilation ditches, warehouses, etc. 】

With the narration and subtitles, in the video footage on the high-altitude giant screen, the internal situation of the 816 Nuclear Project appeared bit by bit in front of the ancients who watched the high-altitude giant screen in the past dynasties.

【The largest cavern is the main building of Reactor 101. The internal hall extends from the third floor to the ninth floor, with a height of approximately 79.6 meters. The hall on the eighth floor alone is twenty or thirty meters long.】

【The entire 816 nuclear project is divided into 11 floors. The main control room is located on the 9th floor, which houses the most advanced computers in the country at that time. As the control mechanism of the entire reactor, the main control room is like the dispatcher, commanding various aspects of the reactor. Work】

【Opposite the computer console, the densely packed luminescent ceramic pieces on the circular control panel correspond to the 2001 stone-ground water-cooled tubes in the main reaction hall of the 8th-floor nuclear reactor.】

【Every move of each tube will be clearly seen by the staff of the general control studio, which ensures the safety and stability of the nuclear reactor to a large extent.】

【……】

Inside the mountain, the 816 Nuclear Engineering Base looks like a huge maze, which shocked the ancient people of all dynasties.

"too big!"

"It's really amazing to actually hollow out a mountain and build so many things inside!"

"If there is no one to guide you, you will definitely get lost in there."

"It’s incredible! Who would have thought that a mountain that looks normal on the outside actually has an underground city inside?"

"……"

Many ancients were amazed

【The thickness of the covering layer of the entire 816 nuclear project is more than 200 meters, which can prevent the air explosion impact of a 2 million-ton atomic bomb and the direct hit attack of a 1,000-pound bomb, and can also resist the damage of an 8-magnitude earthquake. 】

Hearing this news, the ancient people of all dynasties were shocked again.

They had already fully seen the power of the atomic bomb in previous videos.

That is the power to destroy the heaven and the earth.

And this huge underground city can actually resist the attack of atomic bombs. It is simply too strong!

The plane of Ming Taizu.

Zhu Yuanzhang sighed:

"It seems that the situation in Longguo was really difficult at that time."

Building such a facility, he felt that Longguo was well prepared for a nuclear war.

"Home-changing plan?"

This thought flashed through Zhu Yuanzhang's mind.

【In 1984, due to the national strategic adjustment of the Dragon Kingdom, the project was suspended.】

【On April 8, 2002, the country agreed to declassify the 816 nuclear project】

【In April 2010, some areas of the 816 Nuclear Project Cavern Project began to become tourist projects. County】

Barrage flew out:

"I have been to this attraction and it is indeed magnificent inside! It’s really not easy for the older generation of revolutionary ancestors. I pay tribute to them!"

"Reply - Indeed, it was too difficult for the martyrs. Under the conditions at that time, it would have cost too much to build such a grand project!"

"I've been there too, it feels very cyberpunk style"

"I've been there before and it was so shocking, I can't imagine how it was built at that time!"

"……"

After the entire video was played, the ancient people of all dynasties were still shocked.

This project of hollowing out a mountain is really magnificent!.
