A day later.
Zhu Gaochi sent Zhang Bao to discuss the purchase of five coal mines in the suburbs of Beijing.
To the current Zhu Zhanxin.
He had a guess about these mines.
For such a secret manual, there should be an even larger Kuangqu with continuous earth veins.
However, he had to solve the problem of the water pump mines now. He had to find the Ministry of Revenue to confirm it later.
Most of the coal mines here were owned by the imperial merchants of the imperial court.
The so-called imperial merchants were just relatives of the emperor.
Therefore, with the Crown Prince's background, Zhang Bao quickly bought it.
Not to mention the coal mine outside the capital.
Water was coming out of every mine.
Everyone was talking about the underground Water Dragon King.
He could not take these mines at all.
Therefore, these royal merchants were all anxious to get rid of them and even sold them at super cheap prices.
When the contracts for the five Kuangqu were presented to Zhu Zhan Xin.
The corners of Zhu Zhanxin's mouth curled up slightly.
Now the water pump could be set off.
After a day of hard work, the dozens of masters in the craftsman's office had increased by more than a hundred.
After a day of rushing work, they had cut down a lot of bamboo in the imperial garden.
Finally, five artificial water pumping devices were manufactured.
The water pump wasn't that difficult.
It was similar to the recommended pump, and then a long tube connected to the other end.
The water pump was placed in the water, and the other end was placed far away to drain the water.
Another person pumped the water out of the water pump.
Not to mention, the water pump that Zhu Zhanyu had asked the craftsmen to make was one with high water pressure.
Two people were needed to manually pump the water.
The crown prince heard that his son had come up with something new.
He hurriedly ran from the cabinet office to the craftsman's office.
When he arrived, he saw a group of craftsmen gathered together.
Zhu Zhan Xin was standing beside a waterwheel.
"Son…Country Supervisor!"
Hearing his father's voice, Zhu Zhan looked at his father who was running over and waved his hand.""Father, here."
"What is this?"
"This is the treasure to restore coal mining.”
"Ah?"
"Look at Father."
After Zhu Zhanxin finished speaking, he called a few masters over.
Then, he watched as they placed the pump head into the waterwheel. The two craftsmen also jumped into the waterwheel.
After that, Zhu Zhan Xin ordered the craftsmen on the other side to move aside.
Zhu Gaochi looked on curiously and expectantly.
At the same time, he shook his head and smiled bitterly. Even though he had read many books of the Mo family, he could not find such a thing.
Where did his youngest son get so many tricks from the Mo Family?
"Another overseas search?" Zhu Gaochi asked.”
Zhu Zhan touched his nose and replied,"Yes."”
"You brat, you're not honest."
Zhu Gaochi shook his head and sighed. He felt that his son was getting weirder and weirder.
No one knows his son better than his father.
However, the waiter beside him made him more and more confused as a father.
The change was too great!
Seeing that he was ready, Zhu Zhan said to the two masters in the waterwheel beside him,""Begin."
"Alright, Country Supervisor!"
"Fight."
The two craftsmen began to pump air into the waterwheel crazily.
This caused the water pump to form a negative pressure inside.
Zhu Zhan Xin said to his father,"Go forward, father. Let's go to the other side."”
"I want to see what tricks you can play. Those coal mines cost a lot of money.”
"If you knew that your father was thrifty and diligent, would your son lie to you?”
"It better be like this!"
This type of water pump had the simplest principle.
The construction was also very simple.
However, it had never been invented.
This was why no one understood its principle.
Just like the first person to eat crabs.
However, Zhu Zhanyu had brought forward the invention of this pump.
It wouldn't be long before it was invented in the future.
They arrived at the water outlet at the other end 30 meters away.
When the sound of flowing water sounded.
Zhu Zhan smiled.
Crown Prince Zhu Gaochi was stunned.
Water from the water cart kept gushing out of the bamboo pipe.
The craftsmen around them were also delighted.
They were all extremely excited!
The day's effort was not wasted.
The hard work was worth it.
To Zhu Gaochi.
The bamboo pipe in the waterwheel was much higher than the waterwheel.
People strive for higher ground, while water flows downwards.
This was the logic of the sages and teachers.
However, the scene in front of him had undoubtedly dealt a heavy blow to Zhu Gaochi's understanding.
This type of manual water pump only required the lower valve to be opened and the upper valve to be closed when the valve moved upward. The liquid from the outside would be sucked into the space below the valve, and the liquid above the valve would be pushed upward by the negative pressure to flow outside.
Then, when the plungers moved downwards, the lower valve would touch the chisel and close, and the upper valve would open.
In this way, the liquid, namely the water flow, could be forced from the space below the valve to the space above the valve.
The space above had already been sealed and connected to a bamboo tube that was the only ventilation channel.
The pressure of the water would cause the water below to continuously gush up into the bamboo tube.
Finally, it flowed out.
The water continued to gush out, causing the pressure inside to increase.
In a tight environment, the water flow controlled the air.
He could only push the bamboo tube forward to release the pressure.
Therefore, the water would be drawn faster and faster!
"Dad, now, we can take this thing to the coal mine we bought and start pumping water."”
"How long have you been planning this? This is even more profitable than white sugar."
Zhu Gaochi was not stupid.
After the five coal mining areas resumed mining.
Without a doubt, it would allow the Crown Prince's Residence to make a huge profit this winter.
Zhu Zhan Xin pondered for a while and said,""White sugar is a small but long-term solution. As for the coal mine, I have other plans.”
"Sigh!" Zhu Gaochi sighed,"You are indeed more powerful than your father as a country supervisor.”
"Father taught me well."
"Hahaha, you brat!"
……
When the people from the Ministry of Works and the master of the Craftsman Institute appeared at the five coal mines in the suburbs of the capital.
The person in charge was already waiting there.
They had already hired laborers.
Zhang Bao was also in one of the coal mines.
When the water in the mine was continuously pumped out of the surface and discharged into the dug canal, it flowed down the mountain.
Zhang Bao was shocked again.
The last time he saw White Sugar, he was impressed by the ability of the country supervisor.
Now, he saw a mechanism that could extract water from the ground.
They were so shocked that they were dumbfounded!
The country supervisor said that it was found overseas?
This was too unbelievable!
Zhang Bao also had many business friends overseas.
However, he had never heard of white sugar or something called a water pump.
"The country supervisor is really a great talent!"
Zhang Bao didn't dare to ask for a relative. This nephew of his had a bright future.
At this moment, Zhang Bao only had one evaluation of Zhu Zhan Xin in his heart:
The talent to mend the sky and help the world, the virtue to benefit things and help people!
In less than a day, the water in the coal mines in the suburbs of Beijing had been pumped clean.
Then, the masters of the craftsman's office used the mud of yellow soil and gray stone to continuously fill up the holes that had been dug.
After another half a day!
The five coal mines were no longer flooded.
Manpower had changed the people's so-called " Underground Water Dragon King "!
In the Forbidden City.
Zhu Zhanmo, who had a water pump, asked the Ministry of Revenue to take out the exploration records of the undeveloped waste mines in the suburbs of the capital.
He discovered that there were no less than a thousand abandoned mines in the suburbs of the capital.
At this time, in Zhu Zhanhao's mind, he thought of a place that was recorded in later generations-Jingxi Coal Mine.
The Jingxi coal mine had been mined for a thousand years from the Liao Dynasty until the Qianlong period, and it had even fed the entire Beijing and Tianjin.
At this moment, Zhu Zhan's chest was filled with excitement!
He only felt that he had already grasped the entire future wealth of Da Ming!
Now, there were puddles of water.
And they were all ownerless.
If he didn't make a move now, when would he?
Zhu Zhanxin rushed to the palace where the cabinet office was located and found Zhu Gaochi directly.
"Dad, I bought the ore!"
