The moment he saw the steam engine, Wang Ningan almost wanted to cry.

This stuff is just too important.

With the steam engine, it can drive trains, with the most conservative estimates, 10 trains, each 30 tons, is 300 tons, a horse can pull up to 1,000 catties, 300 tons is the full load of 600 horses, and the train can sleep endlessly, the efficiency is several times higher.

In other words, with a steam engine, the work efficiency can be increased by a thousand times, ten thousand times.

High efficiency must lead to high output, to create abundant and cheap goods, to easily arm a strong army, and to make the mobilization capacity skyrocket.

Once you have mastered the power of industry, even if it is a frontier island thousands of miles away, you can easily conquer the Central Empire and take what you want.

The steam engine gives people the power of God, and he has worked hard for so many years, and finally saw the appearance of the steam engine, which is like a daughter-in-law who has been boiling into a wife for many years.

Even if his changes and his efforts all fail, as long as the steam engine is still there and can master the power of industry, China will sooner or later rule the world.

Therefore, Wang Ningan even has an idea that he can retire after success, and his wife and children can enjoy it, no matter what happens, it has nothing to do with him, and he can live his own small life.

Of course, this was just his momentary thought, because Wang Ningan soon discovered that this steam engine was not as great as he imagined, on the contrary, the things in front of him were still very simple, so simple that Wang Ningan did not believe that it could drive a train and open the steam era.

Wang Ningan decided to take a good look at the invention in front of him.

Although he was not good at hands-on, when he knew at least some mechanical principles, he quickly understood them.

The steam engine invented by Xu Yang was two egg-shaped containers.

First, through the boiler, an egg container is filled with steam, and then the inlet valve is closed, and cold water is sprayed outside the container to condense the steam in the container to form a vacuum.

Then open the water inlet valve, the water at the bottom of the mine is sucked into the container through the water inlet pipe by atmospheric pressure, the water inlet valve is closed, the steam inlet valve is reopened, and the water in the container is pressed out through the drain valve by steam pressure. When the water in the container is emptied and filled with steam, close the inlet and drain valves and re-spray the water to condense the steam. In this way, the two sets of devices work alternately, and the water can be continuously drained.

According to Xu Yang, the stagnant water that used to take a month to drain now takes only half a day at the earliest.

The miners liked it so much that he was going to roll it out in all the mines.

Xu Yang was elated, but Wang Ningan frowned.

He spent a lot of effort to train craftsmen and encourage inventions, and finally came up with a drainage device, which was too much of a failure, and what was in front of him was too far from what he had asked for.

Even the dog's teeth doubted, can this thing continue the 500-year national fortune of the Great Song Dynasty?

Daddy, isn't that how cowhide blows?

Facing the questioning gaze, Wang Ningan was a little unable to hang up.

"Xu Yang, you immediately gather all the craftsmen, let's study it together, and see how much room for improvement there is in this thing!"

Xu Yang was also taken aback, the thing he had finally come up with did not enter the master's eyes, which made him a little embarrassed.

Because three years ago, Wang Ning'an arranged it, hoping that they could study a machine that did not rely on human and animal power, and did not need to be driven by wind and water.

Xu Yang dug out his mind to find the answer, once he was eating breakfast at a roadside stall, he found that the white steam in the steamer jumped up, it was originally a windless day, but the white steam was blowing in the guise of moving, constantly floating upward.

When he saw this scene, Xu Yang suddenly brightened.

He finally found the answer.

and senior brothers and brothers, as well as many craftsmen and masters, worked for more than two years before the development was successful, and then hurriedly told Wang Ning'an.

That's the experience.

They have failed too many times, the hardest step has come out, and nothing else can stump them!

When Wang Ningan gave the order, everyone rushed over.

Wang Ningan took everyone to carefully observe, calculate, and comprehensively evaluate the machine in front of them.

In the final result, Wang Ningan was very disappointed.

The efficiency of this steam engine was outrageously low, and if it weren't for the coal mines, it would hardly cost to burn coal, and no one could afford it! And the machine is too big to be powered.

"Now we have to do two things, one is to improve energy efficiency, and the other is to reduce the size ...... As for how far, it's hard to say, but I can only tell you that I hope to make this thing replace hundreds of horses, carrying goods, galloping on the road. ”

Hearing Wang Ning'an's words, even if even the dog's teeth spurted blood, Dad, you are too good at thinking, why can't I see it, this thing is so amazing?

The son's doubts are nothing, the key is these craftsmen, after all, they are the real practitioners.

Everyone squatted on the ground, and they took the branches and paddled around on the dirt, and the quarrel became more and more intense, and one by one they rolled up their sleeves as if they were going to fight.

In the end, everyone finally came to a consensus, Wang Ningan's idea is not impossible, the current steam engine is from the mine, lifting water, if the steam engine is flat, install the transmission device, and run it, of course it can take the vehicle away.

But the problem is that the weight of the steam engine is too large, and the steam produced is not enough to propel the steam engine, so it is sad.

In the following days, Xu Yang led the craftsmen to go all out.

Wang Ningan has never been so serious, he didn't even go to Youzhou, he stayed in Xishan, ate and lived with the craftsmen, discussed it together when he had the kung fu, and when he encountered a problem, he thought of a way together.

……

"I'm a little scared!" Gouya'er said in a low voice: "Even if he went to the court and dealt with the affairs of the court, my father has never been so serious!" ”

Xiao Guanyin nodded, "I'm also quite afraid, will the prince change into a different person?" ”

Gouya'er was even more afraid, "Master, do you want to invite a few monks and Taoists over to exorcise evil spirits?" ”

Xiao Guanyin slapped him hard, "What Taoist priest please, go and invite your grandparents!" They'll be able to stop your dad! ”

"Yes!"

Dogtooth jumped up and hurried to Youzhou.

Father Wang and the Bai family have been waiting for a long time, but they didn't wait for their son, but for their grandson.

Hearing that Wang Ningan plunged into the West Mountain, these two couldn't sit still, so they killed directly.

Xiao Guanyin looked at it, thinking that there were two elders here, who could convince Wang Ning'an!

Who knew that in the end, only the Bai family was left, and he came out.

"Hmph, that dead ghost has been puffing out of the same nostril with his son, let's go home and leave them alone!"

Bai snorted angrily and pulled Xiao Guanyin back to Youzhou, and Gouya'er also followed her grandmother and ran away together, the eldest young master really couldn't stand the simplicity of Xishan.

After enjoying a few days of good life in Youzhou, on the tenth day, Gouya'er couldn't sit still again.

He promised Zhao Shu to find out what this great invention was, and the little emperor was still waiting!

Gouya'er was about to go to Xishan to have a look, but he happened to bump into Bai's and Xiao Guanyin, each of them holding a big food box, which contained delicious food.

"Alas, we two mothers, it's a hard life!"

From this day on, almost every three or five days, I had to deliver some food.

Wang Ning'an and Father Wang both stayed in Xishan, and then gradually the dogtooth did not come back, and the eldest young master finally discovered the fun of the steam engine.

The craftsmen made a gradual progression, first of all, they designed a special lifting pump, so that it was not necessary to alternate with two egg-shaped devices, and the structure was greatly simplified.

That's not enough!

Wang Ning'an noticed that the efficiency of the steam engine was low, mainly because it condensed directly in the cylinder, and the heat was lost too much...... He put forward his opinion, Xu Yang immediately started, and it took half a month for them to design an independent condensing tube. But then, they found that every time they worked, some air and condensate would remain in the condensate pipe, which would affect the efficiency, so they added an air pump, and later they added a sandwich to the outside of the cylinder......

In this way, continuous improvement, continuous verification, the steam engine is constantly shrinking at a speed visible to the naked eye.

Dogtooth was dumbfounded, he still remembered, the first time he saw it, how simple it was, and now, he can't believe that the thing in front of him is the same thing as the ugly duckling at the beginning!

It's really different, the original can only be called a steam device, and it's still far from a steam engine!

It stands to reason that it will take decades, or even hundreds of years of accumulation and exploration, to complete the transformation and truly manufacture a qualified steam engine.

However, because of the appearance of Wang Ningan, the situation has taken a turn.

Although he doesn't know how to do it, when he at least understands a lot of principles, technical things, often just a layer of window paper, pierced, and suddenly realized.

In addition, in the past ten years, the Baigong Academy, as well as the craftsmen of the Great Song Dynasty, who manufactured weapons and armor in batches, have accumulated rich technical reserves.

Under the command of Wang Ningan, it finally came into play.

It took a little more than four months for the world's first steam engine to finally appear.

It can no longer be used only to pump stagnant water, but can also be used to drive vehicles.

Wang Ningan asked people to lay a ten-mile-long simple railway track in a month, and made three more carriages, which were hung behind the front of the steam engine-driven locomotive.

"Come on, let the world see the power of engineering men!"

These days are busy surviving, Wang Ningan's hands are also full of calluses, he waved a shovel, and the coal was thrown into the hearth, Wang Liangjing laughed and followed.

The fire was blazing, and the steam engine was running.

After a brief jolt, the three-car train clicked forward, not fast at all, almost like an ox cart, but there were more than a hundred people sitting on it!

All the craftsmen involved in the manufacture of the steam engine, one of them was in decline, all standing on it, they looked at it with novelty, waved their hands incessantly, and some of them shouted excitedly, venting their excitement in their hearts.

When the train came out of the mountain, it was just in time for Bai and Xiao Guanyin to come over to deliver thick clothes, and they saw three generations of the Wang family's ancestors and grandchildren, like little ghosts, standing at the front of the car and smirking.

In this moment...... Their eyes were full of tears!
