Zhou Xian nodded and said, "It's okay to sell these things to you, but I have a request, I don't know if you can agree." ”

When Zheng Huayuan heard that Zhou Xianneng sold things to them, he immediately asked excitedly, "I don't know what Lord Zhou wants?" ”

Zhou Xian said: "I set up a Zhou family chamber of commerce, only join my Zhou family business, will become a member of the chamber of commerce, can buy a large number of items produced in my factory, of course, my Zhou family chamber of commerce will not interfere with your business, just ask our Zhou family chamber of commerce in the future to have anything to need, you should give priority to sell to our Zhou family chamber of commerce." ”

The four of them were a little hesitant when they heard that Zhou Xian wanted them to join the Zhou Family Chamber of Commerce, but Zheng Huayuan opened his mouth and said, "I wonder if there are any other restrictions after joining the Zhou Family Chamber of Commerce?" ”

Zhou Xian said with a smile: "There are no other restrictions, just to facilitate our Zhou Family Chamber of Commerce to better purchase items, don't hide a few, in the future, our Zhou Family Chamber of Commerce will also increase conditions and restrictions on those who want to join, so it is a rare opportunity for a few people to join now." ”

The four of them got together and whispered something, and Zhou Xian didn't care about them eating by themselves.

Li Huafeng, who was on the side, was also thrilled when he heard Zhou Xian say that a Zhou family chamber of commerce had been established.

These people from Jiangnan don't know Zhou Xian's ability, but Li Huafeng knows Zhou Xian's talent, and he has made so many new things in just three or four months, and he may be able to make something in the future.

Zhou Xian was asking the wealthy businessmen in Jiangnan, but he couldn't say that he wanted to join the Zhou Family Chamber of Commerce, so he had to wait for these wealthy businessmen in Jiangnan to agree.

After the four of them discussed for a while, they sat down again, Zheng Huayuan smiled and said to Zhou Xian: "The four of us just discussed, and we decided to join the Zhou Family Chamber of Commerce. ”

Zhou Xian said with a smile: "Okay, the four of you are really a wise move, in the future, the four of you will definitely be proud of the decision made today, tomorrow you will go to my Zhou Mansion to sign a contract, and in the future, you will all be from my Zhou Family Chamber of Commerce, and I will give you unlimited supply of goods at the lowest price." ”

The four of them were overjoyed when they heard that Zhou Xianhui would supply unlimited goods at the lowest price.

At this time, Li Huafeng interjected: "Nephew Zhou, I wonder if my Li family can join the Zhou Family Chamber of Commerce?" We've worked together many times."

Zhou Xian nodded and said, "Uncle Li naturally has no problem joining my Zhou Family Chamber of Commerce, and he will go to my Zhou Mansion tomorrow." ”

Li Huafeng was overjoyed when he heard this, and said to Zhou Xian: "Nephew Zhou, I, Li, really didn't misunderstand you, I am really a righteous person." ”

Everyone agreed on the matter, and they drank and chatted together.

Zheng Huayuan and others told Zhou Xian what they saw and heard when they were doing business around.

It wasn't until noon that the banquet dispersed, and Zhou Xian and Li Huafeng went back to their homes after walking out of Yihong Mansion.

After Zhou Xian returned to the house, he asked Xiaoqing to find Zhou Fugui.

Zhou Xian told Zhou Fugui about the establishment of the Zhou Family Chamber of Commerce, and let Zhou Fugui serve as the president, so that he was responsible for dealing with these wealthy businessmen.

Zhou Xian himself has a lot of things to do, and he has no time to waste on doing business.

Zhou Xian thought that there would be more and more things to manage in the future, so he asked Zhou Fugui to go to his hometown to find some more reliable people in the clan to come to Monkey Mountain Village.

Zhou Fugui heard that Zhou Xian asked him to go back to his hometown to find someone, and he was immediately in high spirits.

After saying yes, I couldn't wait to go out and prepare.

Zhou Fugui's hometown is in the remote Zhoujialing of Shanxi Province, and it takes about three days to ride back.

Zhou Fugui has not returned to his hometown for several years since he left his hometown last time, and this time he returned to his hometown to recruit people, and it can be said that he has returned to his hometown.

After arranging Zhou Fugui's affairs, Zhou Xian came to the study and began to draw the structure of the steam engine.

Now with the sales channels of wealthy businessmen in Jiangnan, the production speed of the factory is somewhat unable to keep up.

So Zhou Xian decided to build a steam engine, and with the help of a mysterious ball of light, Zhou Xian decided to make a more practical horizontal steam engine.

The principle of the steam engine is very simple to say, but it is very complicated to manufacture.

Fortunately, Zhou Xian has a mysterious ball of light, which allows workers to learn everything in one step, without having to spend a lot of time and energy slowly exploring.

After an hour of painting, Zhou Xian finally finished painting, put down the brush, stretched and looked out the window.

It's July now, and the sun is scorching outside.

It has been four months since I came to this era, and I have not made any great achievements, so I must seize the time to develop, and time waits for no one.

After making up his mind, Zhou Xian rushed to Monkey Mountain Village with the drawn steam engine structure diagram under the scorching sun.

When he arrived in Monkey Mountain Village, Zhou Xian came directly to the arsenal, and after finding Zhao Laoyan, he asked him to gather a hundred skilled craftsmen.

Soon, Zhao Laoyan brought a hundred craftsmen to a large conference room.

This conference room was built at the request of Zhou Xian before, and like the classrooms of later generations, it was mainly used to discuss some things at work.

This conference room can accommodate more than 300 people, and now it seems spacious to enter 100 people.

Zhou Xian stood on the podium, looked at the craftsman sitting below and said, "I came to you today to make a machine that can change an era, and it is the steam engine!"

There was an exclamation below, all the craftsmen looked at Zhou Xian excitedly, and Zhao Laoyan also asked excitedly: "My lord, are you telling the truth?" Is this steam engine really that magical? Able to change an era? ”

Zhou Xian replied: "Of course it is true, the steam engine led us into the industrial age, and after entering the industrial age, our production efficiency can be increased by dozens or hundreds of times." ”

The craftsmen cheered, and Zhao Laoyan also cheered excitedly.

Zhou Xian looked at the group of cheering craftsmen below and nodded with satisfaction and continued: "Everyone be quiet, and I will teach you how to make a steam engine." ”

As he spoke, Zhou Xian hung the steam engine structure diagram on the wall, and then began to tell.

The principle of the steam engine is mainly to convert the energy of steam into mechanical work. The steam engine is mainly composed of cylinder, base, piston, crank connecting rod mechanism, slide valve distribution mechanism, speed regulating mechanism and flywheel.

Centrifugal governor: The function is to stabilize the steam input, so that the power is stable.

Safety valve: It is to use the lever or spring to press the exhaust port until the steam force is greater than the lever or spring pressure, and the steam is discharged from it.

Pressure gauge: Install the pressure gauge, you can intuitively see the pressure in the boiler and steam engine, the pressure is too low to pressurize, and the pressure is too high to release the pressure.

The best sealing method for the steam engine is to seal it with a copper piston ring, and the head and tail of the cylinder are sealed with a copper gasket.

It took half an hour to explain all the principles and details of the steam engine.

Fortunately, through the influence of the mysterious ball of light in Zhou Xian's mind, all these hundred craftsmen already knew it, as if they had built a steam engine countless times.

Next, as long as these craftsmen worked together, they would soon be able to build the first steam engine of the Ming Dynasty.
