It may be that Zhu Yunwen's arrival psychologically inspired the craftsmen in Shanxi, and the cylinder, which was originally scheduled to take ten days to build, was completed on the eighth day, and then the boiler, cylinder, piston and transmission parts were connected overnight to prepare for the next day's experiment, and the viewing platform prepared for Zhu Yunwen, the emperor, was also built.

This is the first attempt in human history to apply the steam engine to the field of practice.

On the day of the trial, Zhu Yunwen woke up very early, not because he couldn't fall asleep with excitement, this was just a habit he had for so many years.

For more than ten years, except for a few drunken sleeps, the rest of the time often wakes up very early, especially after quitting drinking, the biological clock has long become a habit.

Although he was in Shanxi, there were many important notebooks sent from Nanjing, although most of these manuscripts had been approved by the cabinet, and the routine was to show him, the emperor, and if there was anything dissatisfied, he would return to the cabinet after annotation.

After eating a simple breakfast and putting a thick velvet on the outside of the leather jacket, Zhu Yunwen walked out of his temporary residence in Taiyuan.

The original Jin Palace, which has almost become an attraction.

Outside the mansion, hundreds of officials and officials were already guarding, and there were not too many politenesses, so they left Taiyuan City under the guidance of the steam master and headed towards Guo Wansan's coal pit in the suburbs.

It's not far away, it's at the foot of Cuijin Mountain dozens of miles out of the city, that is, the Luliang area, and the mountain selected by Guo Wansan also has a name, called Taixiao Mountain, because there is a temple on the top of the mountain.

The earliest coal shaft here can be traced back to the Song Dynasty, when the well was more than 50 zhang deep, and then collapsed, and after Guo Wansan took over, he did not dare to dig too deep, and retained about half of the scale.

Guo Da, the richest man in Shanxi, is not only this coal mountain, there is no need to get into a lawsuit for this money.

By the time Zhu Yunwen and his party arrived, Mo Cheng and the others had already set up the steam engine, and Zhu Yunwen was stunned.

That's too big, isn't it?

Zhu Yunwen's impression of the steam engine should not be the size of half a table, but what he saw in front of him was a huge combination that could be comparable in size to the gantry crane responsible for bridge lifting.

"This is a boiler."

If Mo Cheng didn't introduce it, Zhu Yunwen thought it was a super-large dinosaur egg used to hatch a Tyrannosaurus rex.

"The above is the cylinder, the steam in the cylinder expands and collects enough thrust to produce force, which will push the piston port to produce force, drive the piston rod and other transmission parts, here is the water spray valve, is to wait until the piston movement is carried out, the piston cylinder is cooled outside, so that the water vapor in it condenses, so as to bring back the piston rod to return to the origin.

At the other end of the piston rod, we connect the principle of the hand-cranked water pump, set up the water inlet valve, and extend the pipeline into the water pond at the bottom of the well through each valve port, when the water is pumped into the water inlet valve and enters the piston cylinder through the pipeline for a new round of heating, so as to achieve uninterrupted reciprocating motion until all the stagnant water is evacuated. ”

Mo Cheng explained this eloquently, Zhu Yunwen didn't understand at all, but he didn't feel ashamed.

"Let's get started."

Not only Zhu Yunwen himself, but also many quietly selected 'miner representatives' around the mine were also watching, and the big guys were very curious about how such a huge object could be evacuated from dozens of meters of stagnant water just by burning coal.

This doesn't sound realistic.

Several craftsmen opened the valve of the boiler, started a fire, and when it was fired into a small kiln, they filled it with a shovel of coal, and finally closed the valve.

As time passed, Gu Gu's thick smoke came out of the chimney with the slightest swaying flames, and the cylinder on the top of the boiler also began to rumble, and the piston rod connected to the piston boiler shook, and after a while, everyone saw that the valve of another pipe under the piston rod suddenly spewed out a large amount of turbid water.

The moment the turbid water is sprayed on the piston cylinder, it becomes water vapor and evaporates, but the continuous ejection still quickly makes the piston cylinder condense, and gradually, the water spray valve no longer sprays water.

The piston rod is back in its starting horizontal position.

Another new round of reciprocating movement began.

This scene stunned Huang Fu and other officials and miners' representatives.

A person standing on the surface of the earth, only needs to keep filling a boiler with coal and stone, can so easily pump out the water buried in the coal well buried dozens of feet underneath?

It's so easy, what else do you need people to do, what do you want mules and donkeys to do.

Think about it before, in order to drain the water at the bottom of the well, the big guy carried the water out on his shoulder, and it was nothing to be tired, but the knees and feet were soaked in water for a long time, and how many people became disabled when they were not confused.

When they thought of the previous hardships and dangers, some people even began to wipe away tears.

Unlike the longing and excitement of officials and miners, Zhu Yunwen frowned.

"It's a little slow."

Looking at it, the sun was quietly reaching noon, and Zhu Yunwen only saw three reciprocating, so he opened his mouth to comment. Mo Cheng, who was guarding in front of him, hurriedly turned around and bowed: "The minister is ashamed to disappoint Your Majesty." ”

Two hours, walked three times back and forth, the water discharged from the top of the sky is only a few large tanks, to the coal well that does not reach the calf of the water to calculate, I am afraid that it will have to be sleepless for several days, of course, compared to the traditional human and animal power, it is completely different.

"I don't mean to blame."

Seeing that Mo Cheng was a little frightened, Zhu Yunwen opened his mouth and said with relief: "Everything is difficult at the beginning, this steam engine is also the first time that it has been applied to the actual field, we can't be too demanding, in fact, it is enough to be shocked."

In the future, as long as you are on the right path, you can reach the end point both fast and slow. ”

As long as the steam engine is developed, there is no doubt that it is correct, not to mention that the efficiency is already very amazing compared to traditional manpower, even if it is not as good as manpower, it is also a cross-era progress.

"It's three poles in the morning, it's almost time to eat, leave the machine here and continue to run, let's go back to the city."

I saw everything I should have seen, and I saw with my own eyes that Mo Cheng didn't lie to himself, Zhu Yunwen could be regarded as having his wish fulfilled, and he stood up with a smile on his face and prepared to leave: "Mo Qing turned around and left the relevant theories and manufacturing methods of the steam engine to Huang Fu, Shanxi can build more, and it can be regarded as accumulating experience in the process of construction, maybe this opportunity for improvement and progress will appear." ”

Hundreds of people crowded around Zhu Yunwen and echoed, and the huge team left the high platform to watch the ceremony, seeing that Zhu Yunwen, the emperor, was about to be sent to the driver's seat, and everyone could happily return to the city to hold a celebration banquet, when an inopportune and poignant sound sounded.

"Your Majesty, the grass people retribution!"
