In the back garden of the General's Mansion, the original flowers and plants are almost dead, a furnace with a diameter of ten meters and a height of eight meters has been built, and the ink stone crucible is supported inside, which is not all made of ink stone, in order to prevent damage, the outside is tightened with several iron hoops, and the weight itself is not light.

The movable damper, connected to the air duct, a deep pit dug a few meters away, there is a fire channel below, the middle is a regenerative chamber, and then a section of the air duct is connected, and finally connected to the wind drum.

This is a regenerator designed and supervised by Cui Qing under the guidance of Renault, not to mention, it looks similar, and if it is Renault, it may not be better than him.

But this wind drum is a little worse.

The air drum is a blower, looking at the wind drum more than half a meter high, through the air inlet, the fan blades inside are not small, but the arc is completely wrong, and the position of the air inlet is also problematic. Finally, look at the joystick, what is this a play, can it be used?

What is the rocker? It is the crank that the fan blade is connected to, there is no motor here, the wind drum rotates, and it is shaken by manpower.

Anyone with a brain should know that this kind of connecting method, shaking the handle in a circle, the wind blades inside a circle, can be imagined, how fast can the wind drum turn? At such a slow speed, Renault felt that if he found a few winds with large lung capacity, they would not be much smaller than this wind drum.

Don't say it, this wind drum is in Dachu, it is a new equipment, and it really used to blow the wind by manpower.

"Is Cui Qing here?" asked Renault.

"Come on, come on, please sir. "The second time we met, Cui Qing's attitude was very good, and seeing Renault was more affectionate than seeing his own Lao Tzu.

"Is this the wind drum?" asked, pointing to the device on the ground.

"Exactly, this is the best wind drum in Da Chu, strong and durable, with strong wind power. Cui Qing said proudly, if he hadn't come to the southwest, the Dingxi military craftsmen would still be using manpower to blow the wind.

Shake it hard twice, the resistance is big, let go here, and the wind blades on that side will not turn. Looking down and pondering for a moment, Renaud knew that he had thought things simple, and a small wind drum was actually very technical.

If nothing else, he can't make the bearing in the middle of the blade, and don't expect the craftsmen here to make it. This wind drum is a suspended fan blade, and there is no bearing at all.

What is called a suspended fan blade, is to create several metal fan blades, directly fixed on an iron rod, the iron rod is connected to the outside, installed with a handle, the shaking is actually the iron rod, the iron rod rotates, drives the fan blade, and the whole wind drum is integrated.

Outside the fan blades, a box is made of wood, which is to prevent the wind from running, it is meaningless to simply turn the fan blades, the wind is running around, so the fan blades must be placed in a closed space, not fully enclosed, to leave the air inlet.

Renault's eyes were just such a plaything, rudimentary, crude, and completely unreasonable.

Forget it, let's do it yourself, counting on this wind drum to heat up, Renault would rather call a bunch of people to blow hard.

"Get a pen and paper. Renault said, Cui Qing moved so fast, and before Huya could react, a branch had already been delivered in front of him. That's right, it's a branch, and paper is so expensive.

Well, the branches are the branches. Squatting on the ground, Renault drew two gears, the small one on the iron rod, the large one connected to the small one, and the large gear with the crank handle.

What a simple transmission, a large gear wheel can rotate dozens of times. It is said that a thousand years ago on the earth, there was a toy called Lego, which had such a function, and it was for children of a few years old, and it was not even at the elementary school level.

"Do you understand? The tooth spacing on this iron wheel should be the same size, and the big gear and the small gear can match each other. "Throw away the branches," Renault explained.

In fact, gear manufacturing is very complicated, and there are very strict requirements for materials and work differences. Renault doesn't need precision gears, just two that can be turned.

The more Cui Qing looked at it, the brighter his eyes became, he was a cultural person, and he understood in a moment that this big wheel with a small wheel could make the fan blades turn faster. The fan blades are fast, which means that the wind is strong, which is not difficult to understand.

"Mr. Xie instructed, and I will let someone build it immediately. "The furnace has not yet been opened, but the small furnace has been prepared in the morning, and there are ten small furnaces, one for each household, which is necessary as a blacksmith.

The things that Mr. wants are extremely precise, and it is not easy to build, but it can be done by ten households, and it will not take long, I am afraid that the size of this gap is not suitable.

He has already thought about it, and he can always pick out the right one for each household.

Cui Qing left, Renault was dumbfounded, he still had something to ask, Cui Qing was in charge here, and the rest were all craftsmen, so they didn't dare to look at him.

"Huya, go and ask, has the ore been shipped back?" This matter can only be asked by Huya, he wants to ask, and those craftsmen can't say anything.

It has been transported back a long time ago, two big carts, more than 5,000 catties, in fact, there is no need to ask Huya, just send Huya away, he remembered to scan it with the God of Wealth, the backyard is so big, the God of Wealth is back in seconds, all piled on the other side of the garden stone platform.

The taste is good, one thousandth is actually a lot, and a thousand catties can produce a pound of flying cow broken iron. Among rare metals, this is quite a lot.

"Huya, go rent some coolies and smash these ores, the more broken the better. "Renault assigned the task, and there were too few people to use, if he hadn't sent the Tiger King out to collect ginseng yesterday, he would have more helpers.

There is no way, who asked him to make a wish, Samtan was all divided all at once, and he could only let the tiger sister refine more. There are not many red ginseng, but green ginseng is easy to pick.

With this lesson, Renault remembered in his heart that he must not make a wish in the future, breaking the fortune is a trivial matter, and it is too delayed.

The most important thing in Dingjun City is coolies, and this is a border city. In the skirmishes with the forty-eight countries, the sand thieves who were cleaned up, except for the diehards, all those who survived were slaves.

Da Chu was a society where slaves were allowed, and there were quite a few of them. Slaves are the best coolies, it's okay to die of exhaustion and beating, as long as you pay.

The owner of the slave, when he is not working, will also rent out the slave, and it is okay for the rented slave to be killed, as long as he loses money.

When I heard that a slave only needed ten copper coins a day, Renaud sincerely repented of how outrageous the rewards he gave to the Yulin Army and the Dingxi Army at the beginning.

spent dozens of times the money and hired a group of uncles who couldn't work, and the transaction was lost.

"Yes sir. Huya turned around, found a team leader of the Dingxi Army, and finished with a few words, Renault looked happy, okay, there is growth, Huya knows how to instruct people to do things.

Then there is some trouble, there is a shortage of water in the southwest, there is no river near Dingjun City, there are thousands of wells in the city, and Dingjun City is built here because the groundwater level here is high enough, and water can be produced by digging a well.

It is not a problem for people to eat and drink, but if you want to wash the mine with well water, it is unreliable.

Invention is really not a human job.

Crushing saves firepower, and ore washing can be de-imposed, which are all necessary processes. But when you ask someone, you can find out that Da Chu smelts iron, except for the large pieces of ore that will be small, and it will not be crushed at all, as for the ore washing, the craftsmen are confused, who the hell is okay when they are full, and bathe the stones? Don't you know that there is a shortage of water in the southwest? Even people don't take a bath, and the ore is washed and burned.

Well, if you don't wash it, you won't wash it, and Renault is not ready to make steel anyway, just get the flying bull broken iron out of the ore.

The God of Wealth is powerful, and the basic attributes scanned out are very comprehensive. The melting point of iron is more than 1,500 degrees, and the flying cow is only 1,000 degrees of broken iron, and he doesn't even need to wait for the ore to melt completely before he can get things out.

It is good to be a nobleman, as long as he moves his mouth, there are countless people to work, the back garden has become his territory, craftsmen and slaves together, almost five hundred people are busy.

When it gets dark, enough ore has been crushed for a furnace, which is still Renault's high requirements. It's a pity that the equipment can't work, relying on the hammer, there is no hope of smashing out the ore powder, so you can only try to break it.

No matter what time it is, Renault gave an order and began to add materials, hundreds of catties of ore, under the busyness of more than a dozen craftsmen, it was done in half an hour.

Don't wait for Cui Qing, he has been working on the two broken gears for most of the day, and he hasn't made a pair that can be used, so let's do it first.

The crucible is full of charcoal, put in the torch, turn the wind drum, and after a while, the fire is shining in the sky, the heat is everywhere, and the charcoal of Da Chu is still quite authentic.

After burning for an hour, Renault couldn't stand it, which was too slow. According to the craftsman, it would be at least two hours, and seeing that he was bored and his stomach was empty, Renault decided to go back and eat his fill.

In Renault's small courtyard, people came and went, and they were instructed by four female officers. Originally, the ninth princess only brought Si Ji and Si Wu with her, but if she wanted to make paper, she didn't have enough manpower, so she transferred the other two cronies Si Qin and Si Hua.

"Hello, sir, please. Seeing Renault come back, everyone stopped and greeted each other in unison, with admiration in their eyes.

"Are you busy making paper?" Renault was quite surprised, this ninth princess is still an anxious child?

"Exactly, the homework arranged by Mr. Yihe dare not slack off. The Ninth Princess said.

"Well, there's no rush in this matter, eat first, it's already dark, it's better to rest early. "Renaud still has a conscience, and although he is anxious to use toilet paper, he can't use the sixteen-year-old princess as a mule.

"Mr. Xie cares, Yihe is not tired, so he ordered someone to pass the meal. "It is more important for everyone to put down their work and wait for the gentleman to eat.

Renault threw up the small wooden stick again, ate the sea plug, it was comfortable to be served, and then took a hot bath, relaxed, let the princess go back to rest, turned around and ran to the back garden with the tiger teeth, the God of Wealth has been staring at it, after two hours of calcination, most of the ore has just burned red, and the flying ox has broken the flow of iron, which has been melted out.

The density of iron is higher, so the dissolved solution is floating on the surface, and Renault deliberately makes people add the material, which is high around and low in the middle, so that the solution flows to the center and is convenient for taking the material.
