In the back garden of the General's Mansion, the original flowers and plants were almost the same. A furnace with a diameter of ten meters and a height of eight meters has been built. There is a crucible of ink stone inside. This is not all made of ink stone. In order to prevent damage, several iron sheets are tightened outside, which is not light.

The movable damper is connected to the air duct. A deep pit is dug a few meters away. There is a fire channel below, a heat storage room in the middle, and a section of air duct is connected to the wind drum.

This is a heat storage room designed and supervised by Renault and Cui Qing. Not to mention, it looks similar. If Renault is not the case, it may not be better than him.

But this wind blow is a bit bad.

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

What is a rocker? It is the shaking handle connected to the wind leaves. There is no motor here. The wind drum rotates, and it depends on human power to shake it. The wind drum in front of me is directly connected to the wind blade.

Anyone with a brain should know that if you shake the handle and turn the wind leaves inside, you can imagine how fast the wind drum can turn? With such a slow speed, Renault felt that looking for a few people with high lung capacity, the wind blowing out would not be much smaller than this wind drum.

You can't say that Fenggu is in Dachu, it is a new equipment, and it used to be a manpower to blow the wind.

"Is Cui Qing here?" Renault asked.

"I'm here, come, please feel free to you." When we met for the second time, Cui Qing's attitude was very good. Seeing Renault was even more intimate than seeing her own son.

"Is this Fenggu?" asked, pointing to the equipment on the ground.

"That's right, this is the best wind blow in Dachu, which is strong and durable, and has strong wind power." Cui Qing said proudly. If he hadn't come to the southwest, the Dingxi Army's craftsmen would have used manpower to blow the wind.

After shaking it twice, the resistance boss was getting stronger. Let go of it, and the Fengye on the other side stopped turning. He lowered his head and pondered for a moment. Renault knew that he had made things simple. A small Fengbo was actually very technical.

Not to mention anything else, he can't make the bearings in the middle of the wind blades, and don't expect the craftsmen here to make them. This wind drum is just a suspended fan blade and has no bearings at all.

What is a hanging fan blade? It is to create several metal fan blades, which are directly fixed to an iron rod. The iron rod is connected to the outside and installed with a handle. The one that shakes is actually an iron rod. The iron rod rotates and drives the fan blades. The entire wind blow is integrated.

A box was made of wood outside the fan blade to prevent 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, and it cannot be completely closed, so the air inlet must be left.

What Renault saw was such a play, simple, rough, and completely unreasonable.

Forget it, let's do it yourself. Reynold would rather let a bunch of people breathe vigorously when he expects this kind of wind to heat up.

"Get paper and pen." Renault said. Cui Qing was so quick. Before Huya reacted, a branch had already been delivered to her. That's right, it was a branch, and paper was so expensive.

Well, the branches are just branches. Squatting on the ground, Renault started drawing, with two gears, small ones hooked on the iron rod, large ones connected with small ones, and large ones fitted with large gears.

What a simple transmission. A large gear wheel can rotate dozens of times. It is said that a thousand years ago on Earth, there was a toy called Lego that had such a function. It was for children of aged 1000 years, and it was not even considered an elementary school level.

"Do you understand? The spacing between the teeth on the iron wheel is the same size, and the large gears and pinions can cooperate with each other." Renault explained a few words.

In fact, gear manufacturing is very complicated, and there are strict requirements for material and workmanship. Such precision gears cannot be made here. Renault does not need precision gears, as long as two can rotate, it will be done.

Cui Qing's eyes became brighter the more he looked. He was a cultural person. He understood in a moment that this large wheel with a small wheel can make the fan blade turn faster. Faster fan blades mean strong wind power, and this principle is not difficult to understand.

"Mr. Xie's advice, I'll make someone immediately." The furnace has not been opened, but the small furnace has been prepared in the morning. There are ten small furnaces, one furnace for each household. As a blacksmith, it is necessary.

What the teacher wants is extremely precise and difficult to build. It can be used together with ten households, and it won’t take long. I’m afraid that the gap is not the right size.

He had already thought about it and each household had one set and could always choose a suitable one.

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

"Huya, go and ask, has the ore been shipped back?" Huya could only ask this matter. He wanted to ask, but those craftsmen were not talking smoothly.

It had been shipped back a long time ago, with two large trucks, more than 5,000 kilograms. In fact, there was no need to ask about Tiger Teeth. As soon as Tiger Teeth was sent away, he thought of scanning it with the God of Wealth. The backyard was so big, and the God of Wealth returned instantly, and it was piled on the other side of the stone platform in the garden.

The taste is good, one thousandth is actually quite a lot, and one thousandth of the flying cow breaking iron can produce one thousand pounds. Among rare metals, this is already quite a lot.

"Tiger teeth, go and rent some coolies and smash the ores, the better the more they are." Renault had to use too few people to assign tasks. If he hadn't sent the Tiger King out to collect ginseng yesterday, he would have had more helpers.

There was no other way, who made him make a wish, and all the ginseng elixirs were divided all at once, so I could only let the tiger girl refine more. There was not much red ginseng, but the green ginseng was easy to pick.

With this lesson, Renault remembered it in his heart and must not make wishes in the future. Losing money is a trivial matter, and it is too delayed.

Dingjun City is the most lacking in coolies, which is a border city. The small conflicts with the forty-eight countries and the sand thieves who cleared out, except for the deadly hard elements, all those who survived were slaves.

Da Chu was a society where slaves were allowed to exist, and the number was quite considerable. Slaves were the best coolies. They were exhausted and beaten to death, as long as you paid.

The slave owner will rent out slaves when he is not alive. It is okay to kill the rented slaves, just pay for them.

I heard that when a slave only had ten copper coins a day, Renault truly repented. How outrageous was the reward for the Yulin Army and Dingxi Army?

I spent dozens of times the money to hire a group of old men who couldn't work, and the business was a loss.

"Okay sir." Huya turned around, found a Dingxi Army team, and finished it with a few instructions. Renault was happy to see it. OK, I have made great progress, Huya knows to instruct people to do things.

Next, there is some trouble. There is a shortage of water in the southwest. There are no rivers near Dingjun City. There are thousands of wells in the city. Dingjun City is built here because the groundwater level here is high enough that water can be emitted by digging any well.

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

Invention and creation are really not a job that humans do.

Crushing saves firepower, and washing ore can remove miscellaneous processes. These are all necessary processes. But after asking someone, I found out that the iron smelting of Dachu will be small, except for large pieces of ore, and it will not be crushed at all. As for washing ore, it was stunned by the craftsmen. Who is fucked and it is okay to bathe the stones? Don’t you know that there is a shortage of water in the southwest? Even people don’t take a lot of bathing the ore, just use it to burn it.

Well, if you don’t wash it, you won’t wash it. Anyway, Renault is not ready to make steel. Just get out the flying cow and broken iron in the ore.

The God of Wealth is powerful, and the basic attributes scanned are very comprehensive. The melting point of iron is more than 1,500 degrees, and the iron of Feiniu cuts off the flow is only 1,000 degrees. He doesn't even need to wait until the ore is completely melted to get the things out.

Being a noble person is good. As long as you move your mouth, countless people will work. The back garden has become his territory. The craftsmen and slaves together have almost 500 people busy.

When it was dark, enough ore had been broken, which was still Renault's requirement. Unfortunately, the equipment was not good, and relying on a hammer, there was no hope of smashing out the ore powder, so he could only try to break it.

Regardless of the time, Renault ordered and started adding materials. The hundreds of kilograms of ore were completed in half an hour with the busyness of more than a dozen craftsmen.

Before Cui Qing could do it, he had been working on the two broken gears for a long time, and had not yet made a pair of them that could be used. Let's do it first.

The crucible was filled with charcoal, and the torch was put into it, and the wind blew. After a while, the flames surged into the sky and the heat was everywhere. The charcoal from Dachu was still quite authentic.

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

In Renault's courtyard, people were coming and going, and they were ordered by four female officials. Originally, the Ninth Princess only brought Si Ji and Si Wu around her, but she wanted to make paper, but she didn't have enough staff, so she also transferred the other two trusted Si Qin and Si Hua over.

"Sir." Seeing Renault come back, everyone stopped and greeted each other, with admiration in their eyes.

"Are you busy making paper?" Renault was quite surprised. Is this ninth princess still impatient?

"That's right, Yihe dare not neglect the lessons arranged by the teacher." said the Ninth Princess.

"Okay, there's no hurry to do this. Have a meal first. It's already dark, so it's better to take a break earlier." Renault still has a conscience. Although he is anxious to use toilet paper, he can't use the sixteen-year-old princess as a mule.

"Mr. Xie is concerned, Yihe is not tired, so I ordered people to pass on the meal." Everyone put down their work and served the teacher to eat more importantly.

Renault shook the small wooden stick again and ate the Haisai. It was comfortable to be served by someone. He took a hot bath and was relaxed. He let the princess go back to rest. He turned around and ran to the back garden with tiger teeth. The God of Wealth kept staring at it. After two hours of burning, most of the ores had just burned red, and the flying cow broke the flow of iron and had melted out.

The density of iron is higher, so the dissolved solution floats on the surface. When Reynolds deliberately makes people add materials, the surroundings are high and the middle is low. In this way, the solution flows to the center to facilitate material collection.
