Zhao Huan stared at the figure in the distance, he always felt familiar, but he couldn't see it clearly.

When the car approached, Zhao Huan saw this person's face clearly.

Wang Chongyang?

Wang Chongyang half-squatted on the ground, looking at the teapot on the stone frame in a daze, the lid of the teapot kept turning under the action of water vapor.

This stuff is kind of interesting.

This is anger, endless, and contains the truth of the world, but he can't say what kind of truth it is.

He just knew that it was interesting to look at it like this, and he had been staring at this teapot for a day and a night.

But he still didn't feel tired, he looked at the teapot and then at the coal field on the big slope in the distance, his eyes were bloodshot.

"There's no water! No, that's not it, you can't burn it dry like this! Water, where is the water? Wang Chongyang looked at his water bag in confusion, and the water in it had been wiped out.

"You can't burn it dry. It cannot be burned dry. He muttered to himself with some anxiety.

A hand stretched out from the side, and a water bag reached in front of Wang Chongyang.

"Hehe, there's water again, it won't boil dry." Wang Chongyang was very excited and poured water into the kettle.

With a sonic sound, a burst of steam filled the air, Wang Chongyang's hand shook, and some water was sprinkled on the teapot, which stirred up this water mist!

Wang Chongyang's eyes became brighter and brighter, he stood up suddenly, leaned forward, his whole face almost stuck to the stone frame, and laughed loudly: "Hahaha!" Pregnant! That's it! That's it! ”

Wang Chongyang stood violently, scaring off the person who gave him the kettle.

"This is it! Hey. Wang Chongyang sprinkled the water in the water bag in his hand on the arm of the teapot, stirring up another mist.

The water mist was thick and the scale was slightly less than the first careless.

He poured some more water into the teapot, and the water in the teapot was no longer boiling, and there was no more steam.

At this point, Wang Chongyang was still not satisfied, and threw the coal next to him into the fire under the stone frame, fanning it violently with his sleeve.

It seemed that the water was not boiling fast enough, and he even blew the fan to make the fire stronger.

The water boiled again, the water vapor filled again, and Wang Chongyang sprinkled the water on the outer wall of the teapot and poured it into the water.

The water vapor is gone.

After repeating this several times, Wang Chongyang's eyes became brighter and brighter!

"Hahaha! God help me Da Song! This is the ultimate reason that will be realized in one day! How can the Great Song Dynasty no longer prosper?! Haha, sure enough, my Wang Chongyang is the talent of the world! ”

Wang Chongyang laughed wildly and shouted loudly.

"Wang Wupin, what did you find?" Zhao Huan asked very curiously.

The man who handed over the water bag was naturally him.

Wang Chongyang's face is now blackened by the smoke, and there is no clean place on his whole body, which is not like Wang Chongyang who is hygienic.

"Bold! An dares to mock me Wang Chongyang! My king... Oh! … Meet the official family, the official family is safe. Wang Chongyang's face changed faster than turning a book, from ecstasy to rage, and then to seconds.

It only took a few moments to do it.

The speed at which this guy changes his face is too fast, are you an actor who changes his face in Sichuan Opera?

"I don't know what Wang Wupin found?" Zhao Huan asked. That's the crux of his question.

As soon as Wang Chongyang heard the official ask this, he was overjoyed, and he asked well!

"Official, this Datong coalfield has been mined on a large scale since the Northern and Southern Dynasties, and today the outermost coalfield has been cleaned up, and the rest are buried relatively shallowly. But there are also three zhang deep. ”

"But these three feet deep has become the key to restricting coal mining in all coal fields. Because there is groundwater. I don't know if the official family knows about it or not? Wang Chongyang said smugly.

Zhao Huan nodded, there is a lot of coal in the coalfield, but the coal that can be picked up by bending down has long been taken away.

The rest of the coal can only be filled by human life.

"Do you have a solution to this groundwater?" Zhao Huan asked.

Wang Chongyang nodded and said, "Naturally!" Please see here for officials. ”

Zhao Huan followed Wang Chongyang's hand and looked at it, it was the teapot on the stone shelf, and at this moment, the lid of the teapot was constantly turning.

Could it be...... Steam engine?

Zhao Huan gasped vigorously and asked, "Wang Wupin!" If you tell me why, I'll give you a four-grade official! ”

Wang Chongyang is not an official addict, he just wants to have more rights and make it easier to do what he wants.

"Official, farmer's family has a kind of well for drawing water, and it uses that kind of water pressure well."

In Lee's words, it's the lever that keeps pressing the water rod, and the sackcloth plug can suck the water out of the ground. The official family has never seen it, and the ministers are in a hurry, and they can't understand. ”

Wang Chongyang was a little anxious, the official family was a person who grew up in the deep palace, how could he understand how this water-taking device operated?

Zhao Huan was stunned, he really knew about this kind of water pressure well, and he played with it when he was a child!

It's not the kind of reel, with a well rope, but a water-pressure well that goes down the root pipe to absorb water!

"I know, when I was in Taiyuan City some time ago, I saw it, isn't it the kind of constant pressure lever to press the water out? I know. You continue. Zhao Huan motioned for Wang Chongyang to continue his discovery.

Wang Chongyang was dumbfounded, aren't all officials who don't eat fireworks in the world? Aren't they all sitting on the dragon chair and looking at the world? Do you even know such trivial things?

It is normal for him to have this concern. After all, an emperor once said why not eat minced meat.

"Official, this underground water source is endless, but it is not endless, and when the weather is dry, you need to continue to dig deep until there is water. If there is a great drought weather, there may not be a drop of water in the underground water. This is the reason why people in the great drought are not able to make a living. ”

"The minister was thinking, if the water under this water is drained, won't we be able to dig coal? The coalfields under a few zhang can be used for the Great Song Dynasty, I don't know if the official family can understand the meaning of the minister? ”

Zhao Huan nodded, this Wang Chongyang, he can be regarded as having picked up a treasure.

Wangshan and teapot are the principle of the steam engine.

Great!

"Building tens of thousands of rod pressure wells requires too much manpower, but it is not impossible to borrow this combination of fire and water, and the power of fire, water and steam." Wang Chongyang scratched his ears and cheeks.

But the official's eyes were empty, and he seemed to ignore what he said.

Of course, Zhao Huan didn't care about his suggestion made by Wang Chongyang, in fact, the invention and use of the steam engine was to drain the groundwater and then go down to dig coal.

He was just in the system of the emperor of the special society, rummaging through the books and exchanging them for Wang Chongyang.

The three-expansion reciprocating steam engine is too esoteric, and the structural drawings can be understood, and he Wang Chongyang can't do it, which has extremely high requirements for the process.

He now needed something to get the steam engine off the ground, to give an overview of how it worked.

Zhao Huan searched for a long time, and finally found what he wanted from the special agency system.

"Steam, it's you."
