Judging from the composition, what Guan Zunban said is true, Nanyangwei's steam engine has indeed turned!

Although it only rotates, it is easy to blow up because I don't know the air pressure, and there is no pressure relief structure, no condensation, no water pump, and it still cannot be put into use.

But Chen Mu feels that he is great, and Guan Yuangu is also great.

In this world, the fifth year of Longqing, maybe the fourth winter of Longqing? The Ming Dynasty craftsman Guan Yuangu made the first steam engine.

Even if it can't be put into use, Guan Yuangu took the first step from scratch, which is precisely the most difficult place for Chen Mu, he knows that the steam engine converts steam heat energy into mechanical energy, but he doesn't know how to convert it.

Now the most difficult step has been done by Guan Yuangu.

All that's left is to move forward.

On the day he saw the composition, Chen Mu wrote a letter and sent someone to send a horse to Nanyang, asking Bai Yuanjie to send soldiers to take care of Guan Yuangu's hard work, and asked Guan Yuangu about the next step.

Although he can't make it, he has eyes that can see what's wrong.

For example, the pistons are not compact between them, and this problem requires him to make a better drilling press in the north to solve it; Chen Mu's task for Guan Yuangu was to take the rudimentary steam engine one step further, to condense the steam backflow, to think about how the water pump would work, how to test the internal pressure and properly relieve it.

Chen Mu knew that this was beyond the ability of the ancient craftsmen.

They have strong professional skills and unique ideas, but after making the steam engine, they have already reached the maximum extent they can achieve by making small improvements that have not made much progress, and the problems given by Chen Mu are no longer solved by these talents.

But Chen Mu can give the direction of the problem, if they let them find it themselves, of course they can't find it, not to mention that there is no solution, even if there is a solution, they can't think of where the problem is, and they can't get started. However, after Chen Mu gave the most correct direction, the most difficult problems had been solved.

"A lot of testing, the size of the steam oven and the amount of water are determined, you can inlay a crystal in the shell to see the amount of water, and test the water consumption time. Add a few valves, the water volume is lower than the valve, and the external valve opens the water diversion and releases part of the pressure in the furnace. ”

Chen Mu wrote this in the letter, and also attached a composition of the siphon principle to Guan Yuangu for him to experiment in Nanyang.

He is not in a hurry, he will not be able to use the steam engine for three or five years, but as long as this thing comes out, as long as it can be put into practical use and face the whole world, it will bring earth-shaking changes.

Damn, I'm really tired!

Watching the rider leave, Chen Mu sighed heavily, he also wanted to set up a school, teach students physics and chemistry with the name of Gewu, and make a lot of scientists, if he can build an airplane now-but where does he know what physics and chemistry?

He knows physics, and the cannon can break the bricks.

He knows chemistry, it's gunpowder ignition that pushes cannonballs out.

It can be seen that Chen Mu has extremely high attainments in physics, and when it comes to cannon ejection and smashing 200 things, no one is better than him when he is given a cannon; But to talk about chemistry? He didn't know much about an ancient craftsman.

His craftsmen are removing silver and depositing gold.

Because Chen Mu wanted to let the emperor see the results earlier, he was anxious to ask Shen Jiang for silver. Although the Shen family is a wealthy businessman, it is not easy to make up tens of thousands of silver taels in a while, so he received a lot of gold and silver on the market.

A simple silver tael was no longer enough, and he also sent Chen Mu more than 8,000 taels of gold that was not very good.

It's not that Shen Jiang is sincere and pits Chen Mu, in an era when morality is above all else, businessmen can't achieve great things without integrity. When the gold and silver were delivered, Shen Jiang said that there was enough silver, but more than 8,000 taels of gold could only be worth 35,000 taels of silver.

The old goldsmith instructed more than 40 apprentices to hammer the gold into flat pieces, then cut them into small pieces one by one, wrap them in clay, pour them into crucibles, mix them with stone powder, and melt them, so that the gold of the whole color could flow out.

Chen Mu was not wearing an official robe, wrapped in a mink fur, and stood aside with great interest, and asked the craftsman, "What is that stone powder?" ”

"It looks like you're very much used with General Zhenshuo, and you won't come back to do this drudgery, so it's okay to tell you."

The craftsman may only think that he is a martial artist who walks around the general's mansion, chewing betel nuts and grabbing the stone powder with his hands that often work and have cracked black stains embedded in unwashed black stains for Chen Mu to see, and said with a smile: "This is borax, with this and soil, burning gold can suck away the silver inside, and your general's gold can flow out and recast gold bars and gold ingots." ”

"Suck the silver away?"

"Yes, silver, this fake gold can only be mixed with silver, and now the silver is in the soil, and when the gold is separated, you can take a crucible and put a little lead in it, and you can hook the silver out."

The old craftsman said very complacently, and said, "In this way, the gold and silver are all in the millimeter!" ”

Chen Mu nodded slowly, with just the right amount of admiration in his eyes, this is indeed very wise, and then he heard the old craftsman sigh with emotion: "Your general is really rich, some of this gold is full of color and some is not enough, and the old man has never seen so much gold and silver...... I heard that the General's Mansion is going to recruit craftsmen, is it true? ”

Chen Mu smiled secretly in his heart, and sure enough, it had already come out.

He wants to recruit a group of craftsmen from these craftsmen who came to serve in labor, and this time the best craftsmen in the north and south of the South China Sea were ordered by the Ministry of Industry to come for a period of no more than a year, and another batch will come after a year, because it is labor, so no one pays them, and all that Xuanfu needs to provide them with food and lodging is just to provide them with food and lodging.

Chen Mu raised a group of people, just to pick out a part of them and give them to the moon, and work by his side for a long time.

"Of course it's true, but it's very difficult to be a general's craftsman, only the best craftsmen can be selected, you will come more than a thousand people, and the general will only recruit twenty or thirty." Chen Mu raised his eyebrows and smiled: "One tael of silver per month, each person who has an apprentice in the family will be given another stone of rice noodles, and he is usually in charge of the Ordnance Bureau, and there is a place to supply food in Xuanfu." ”

"If the general has a special order to work, he will give two cents of silver for wine and tea for each working hour, and there will be different rewards for the completion."

The treatment is absolutely generous for the artisan group, and the rewards are added together, and then combined with the Xuanfu to eat, which is equivalent to a net income of three or four taels a month, which is even higher than the income of opening a workshop by themselves.

The old craftsman chewed two mouthfuls of betel nut and said in a Huguang accent: "These are the best craftsmen!" If you are a housemaker for a general, can you be exempted from classsmithing and labor? ”

"That's definitely free!" Chen Mu laughed, he knew that the craftsmen were most concerned about this matter, these best craftsmen were all because they had no money to pay the class silver of the Ministry of Works, so they could only come to work in Xuanfu, he waved his hand and said: "The labor silver of the imperial court, General Zhenshuo will give it!" ”

"When will we be hiring!" The old craftsman glanced back at the busy construction site and said hurriedly: "Lao Er has four sons, all of whom have this craft, and the general will definitely not lose if he accepts Lao Er!" ”

"Don't worry, everyone is here, and we will be notified when the time comes."

Chen Mu left happily, two years, two years to recruit a craftsman camp, there is nothing in the world that he can't make!
