The overall appearance of this good thing that Zhang Tao said is an iron cylinder, and the bottom wall of the iron cylinder has three iron legs, which are fixed on the ground in a triangular shape.

In the middle of the bottom of the cylinder, there is an iron pipe that goes deep into the earth.

There is a piece of rubber inside the iron cylinder, and an iron bar is attached to the rubber, and the iron bar is connected to a handle.

Zhang Tao walked over, looked at the set of iron cylinders in front of him with satisfaction, and said: "The first-generation steam engine built by Shipeng works on the principle of negative pressure. ”

"These days when I have nothing to do, I tried to make a pressure well based on the principle of negative pressure, but I didn't expect it to be really successful."

Zhang Tao was about to demonstrate this kind of pressure well that only needs to be pressed down to be shot, but before he could take a step, Zhu Shun walked over and held the handle, pressed it hard a few times, and a stream of clear well water flowed out of the pressure well.

Zhang Tao originally wanted to shock Zhu Shun, after all, since he knew him, it was them who were shocked every day, and they hadn't seen Zhu Shun much yet.

It's good now, Zhu Shun is not shocked, but Zhang Tao is surprised: "Shipeng, why are you ......?"

Zhu Shun wants to say that this thing is available in every household in later generations, and if it is placed in Daming, it is definitely a divine object, and Daming does not know what the principle of negative pressure is.

It only takes a few gentle pressures to automatically produce water from the pressure well, which is not a god in their eyes.

It is conceivable that as long as this thing is launched, it is also a popular scientific and technological product of Jingshi, and as long as it develops step by step, it can create a big industrialist.

Zhu Shun was about to tell Zhang Tao about the value of this kind of thing, after all, the West French were just a group of invention maniacs, not a group of businessmen who were good at business.

The Zhang family is here.

A young man with a green cloth placket ran over quickly, panting and said, "Dad, the second grandfather asked if you still want to participate in the master's Jiazi memorial." ”

Zhang Tao patted his head and said with a smile: "Shipeng, I'm sorry, every day I study junior high school physics textbooks here, I almost forget about it." ”

"If there's anything, we'll talk about it later."

Zhu Shun waved his hand and said with a flat smile: "Uncle Zhang Shi will go over first if he has something, but he will come back early." ”

"After the new school hall of Beijing Normal University is built, I still expect Uncle Zhang Shishu to teach his protégés."

Zhang Tao smiled even more heartily, he didn't want to say something insincere in the smoky officialdom, his biggest long-cherished wish in this life is to be able to teach, research and research new inventions.

I didn't expect it to come true, and there is also a large amount of monthly money, which can guarantee to feed the family.

Zhang Tao patted the bulging purse, stroked his beard and said with a smile: "Don't worry, the mountain chief, because of these blockages, Zhang will also come back." ”

After speaking, Zhang Tao took his son back and returned to his hometown in Tongzhou.

Zhu Shun looked at such a Qing official Zhang Tao who served the country and the people, and could only walk back, those bureaucrats and squires who had been digging the corners of the Ming Dynasty were all dressed and fed, and they felt inexplicably uncomfortable.

Zhang Tao left, and Zhu Shun also took the little donkey to take a detour back to the Beiping Machinery Bureau to find someone to build a set of pressure wells.

If a fresh commodity wants to sell well, the most important thing is publicity, only good publicity can make the pressure well sell well.

Zhu Shun is ready to use his good brother Xing'an Bogongzi to vigorously promote this kind of automatic pressure well.

It's a summer season.

There is still no light rain in the sky, and in previous years, it was another catastrophe, and many people were starving to death.

What makes the people of Beizhili grateful is that Daming produced two good officials, one named Zhu Shun, who invented a divine object called the Daming steam engine, which can pump water.

The other is Song Yingjing, who is exposed to the sun every day, inspecting the hydrological situation in various places and treating drought.

The common people are looking forward to the rain, and the dignitaries and dignitaries such as the son of Xing'an Bo are also looking forward to the rain, he has not been boating on the lake for several months, and he always feels that something is missing in the days.

The sick son of Xing'an Bo came to his senses on the day of the summer season, and Brother Zhu installed a kind of automatic water artifact for his Zhuangzi in the countryside.

It is said that it was the first to be installed in the whole capital, and the son of Xing'an, who felt that his face was shining, was eager to kiss Brother Zhu.

There is no need for Zhu Shun to say anything, the big mouth of the prince of Xing'an, I can't wait for the children of the nobles in the entire capital to know, and hurry up to the four green buildings in the capital to publicize.

The sons and daughters of the nobles in the capital all know what kind of person the son of Xing'an Bo is, and he can blow a little thing, and he must not believe it at first.

Also automatic water discharge? You are a god.

However, after hearing that the artifact was invented by Zhu Shun, this group of hereditary noble sons, without saying a word, rode Liaodong horses one by one, carrying a smoothbore gun, and hurried to the Zhuangzi of Xing'anbo's family.

The Zhuangzi of the Xing'an Bo family occupies a large area, and it is at least several miles around it, and it is almost catching up with half of the county seat.

In such a large Zhuangzi, the walls are still all red walls and green tiles, and the steps and stone lions at the gate are made of white marble, all of which show two words.

Honorable.

Various pavilions and pavilions were built in the Zhuangzi, and even an artificial lake was dug in the Zhuangzi, which is also the biggest feature of the Xungui Manor.

I can row a boat at home.

There is a bamboo forest next to the small lake, and the pressure well is placed at the entrance of the bamboo forest, Zhu Shun stands next to it, watching the family in Zhuangzi decorate the pressure well, and he doesn't know what to say.

Around the pressure well, a fence was specially used to enclose it, and the material of the fence was actually Huanghuali, and a carver was hired to start the surface of the pressure well.

Or underestimate the role of pressure wells.

Not long after Zhu Shun stood here, a large group of noble sons in brocade clothes came over with muskets on their backs, and Xing'an Bogongzi stood in front with his chest up, saying something loudly from time to time, out of the limelight.

When the noble sons saw Zhu Shun here, they all walked away from the prince of Xing'an, and came over to greet Zhu Shun first.

Zhu Shun responded one by one, looked at the prince of Xing'an, who was full of anticipation, and said calmly: "You come to demonstrate it to the sons." ”

The prince of Xing'an solemnly clenched his fists, pulled open the fence of Huanghuali, and walked in.

The son of Xin Ning Bo took advantage of this time to get close to Zhu Shun and complained, saying that he was not interesting enough, and such a good thing did not think about him first.

Zhu Shun said, I will be the first to help you install it when I go back, which made this new Ningbo boy show a smile.

Xing'an Bogongzi walked to the pressure well, kicked the carver and told him to get out of the way, took out a gold-inlaid water scoop from a wooden barrel next to him, and scooped a scoop of water.

Holding a gold-inlaid water scoop in one hand and a pressure well handle in the other, the prince said solemnly: "Everyone, pay attention, the next time is to witness the miracle. ”

With a solemn face, the prince of Xing'an poured water into the iron cylinder, spread his legs, and walked like a horse.

When the waist and arms are united, the son of Xing'an Bo shouted.

"Here comes the water!"
