Sun Chengping looked around curiously and asked Tao Shiqi beside him: "The stoves for stir-frying steel must be built along the mountain and buried in the ground so that the fire temperature in the furnace can be kept. The terrain here is flat and not suitable, so why did you come here?"

Tao Shiqi said: "The steel furnace to be built in the prison is different from your furnace. It is built directly on the flat ground. Don't worry, I built it when I was in Bozhou. The shape is clear, you just need to follow the instructions."

Sun Chengping shook his head repeatedly: "Since you know how to build a stove, why bother to come to us?"

Tao Shiqi patted his shoulder: "The official said that the geography is different, so the materials used to build stoves will be different. For example, what soil is used to apply the wall of the furnace and what bricks are used to build the furnace. Which locals, who can explain it clearly?"

Sun Chengping nodded: "That's right. The materials used for building the furnace are wrong, but good steel cannot be fried."

Yesterday, when I went to the Blacksmith Furnace to find a big steel-fried company near the Blacksmith Furnace, the Chen family and Niu family were reluctant to do so, and used various excuses to refuse. In the end, Du Zhongxiao felt the trouble and gave up. Fortunately, it was not far from there, Sun Chengping's family also had a steel-fried company. Because the business was not good, it had not been opened. Du Zhongxiao just wanted to find someone with rich experience and choose suitable building materials, so he hired Sun Chengping.

Sun Chengping and his three sons were at home with nothing to do. For the sake of their usual money, they came happily.

Du Zhongxiao confirmed the terrain and said to Chang Du, who was working with the Xiang army, "It's this place. The terrain here is still flat, and the river channel on the other side is deep, which is the most suitable. Two days ago, I made a picture and wrote down the locations everywhere. You summoned the masons and joined the Xiang army under your subordinates, and then we will start. After you have assigned the twenty people making stoves there, follow Tao Shiqi's command."

Chang Du sang his promise with his hands crossed his head and took Du Zhongxiao's picture to arrange the manpower.

The Datong Prison was once Xiazhou, with a large number of mining and smelting under its jurisdiction, and many military soldiers were stationed. Although it is deserted now, most of the troops are still there and there is no shortage of manpower. However, the prison has no money, and these soldiers have not been able to keep their money and food recently, and their morale is not high. Du Zhongxiao has always been generous to those who work. He first distributed the owed money and food to them, and then recruited the people under Changdu to come to do things.

After giving the order to Chang Dutou, Du Zhongxiao came to Tao Shiqi and Sun Chengping, and the few of them hurriedly saluted.

Du Zhongxiao said: "I have transferred twenty people from the Xiang army to help you build the stove. Tao Shiqi is the master of everything here, and Sun Yuanwai assists it. The shape of the stove is as big as when it was in Yongcheng County. There is a lot of iron stored here, so you can get three seats."

Tao Shiqi sang the promise with his hands.

Du Zhongxiao looked around and had all kinds of tools ready. Then he gave a few instructions and sat in a chair to bask in the sun.

The Datong Supervisor chose this place because the river is next to it, which is convenient to use water and iron can be transported out by water. However, the river is too small, so you can only take small boats and bamboo rafts, but you can't take large boats.

Du Zhongxiao built the steel-fried furnace here because he was attracted by this river. With experience in his previous life, he knew that before the steam engine could be used, he should make full use of water conservancy resources. From Datong to the top, the river will no longer be shipped, and the river channel is deep, just for building dams and building hydraulic forging hammers. At that time, the steel produced by the steel-fried furnace can be forged in time while it is red and hot, saving fuel. In fact, not only forging can be used to stir-fry steel, but also iron smelting can be used to make full use of heat and save fuel.

It was very popular to build dams on the river and install hydraulic mills on the river. However, the Central Plains area is flat and once the dam is built, it will affect the water use downstream. Regardless of floods and floods, the large dams are built, which will aggravate the disaster for their own interests. It is precisely because of this that dams are not allowed in most parts of the Central Plains. There are only a few official water mills around Kaifeng.

This is in the deep mountains. Du Zhongxiao has no resistance to building a dam. He can use Datongjian to build an iron smelting center. To deal with the iron accumulation problem of Datongjian, Du Zhongxiao thought about it and increased the processing capacity and processed pig iron into high-quality steel.

Tao Shiqi piled a simple model of a fried steel furnace on the ground and told him carefully to Sun Chengping. Sun Chengping was very curious and had never seen such a furnace before and listened very seriously.

Reflectors are indirect heating methods. They not only raise the furnace temperature, but also have no direct contact with iron. Therefore, coal can be used, and will not have a bad impact on the quality of steel. After all, they are the ones who have been frying steel for a lifetime. Tao Shiqi roughly talked about the structure, and Sun Chengping understood the principle of this furnace and was secretly grateful. Fortunately, he promised to come and help build the steel furnace. After learning these, he could also build one by himself when he went back. This furnace can not only use carbonite, save fuel costs, but also produce more iron and better quality.

Sun Dalang, who was squatting, saw his father listening seriously, whispered to his younger brother beside him: "But I didn't expect that the prison would build such a stove, which is much better than the small stove we used to be. When we learn, we can make a lot of money by relying on this stove. On the other side, Mr. Chen and Mr. Ma refused to come in every way. When our stove is built, I don't know how much regret it!"

Sun Erlang curled his lips and said, "They're standing on a good terrain, and the money they have made over the years is enough."

Sun Dalang nodded repeatedly and smiled. Because of this accident, it was his turn to make a fortune. The cost of steel speculation is extremely high and it is not affordable for ordinary households. The Sun family can only barely maintain a small steel speculation furnace, basically not hiring people, and they can't make much money in a year. However, the Chenniu and his family have strong financial resources and don't know how much money they make in a year, which makes the Sun family envious.

Chang Dutou and several masons in the distance were directing the Xiang army to dig trenches and carry soil. Nearby were Tao Shiqi and Sun Chengping. They discussed the materials used in various parts of the stove and took the Xiang army to dig. Everyone was busy and a scene of being in full swing.

The spring sun is very warm, and it is scattered on the body, making people lazy. Du Zhongxiao sat on the chair without moving, enjoying this rare and peaceful time. Since he arrived in Bingzhou, he has been busy, and the interpersonal relationships in the city are complicated, so he is very tired when doing things.

Datong Supervisory is located in the deep mountains, away from the troubles, allowing Du Zhongxiao to finally calm down. The signing of the judge is either the chief official or the magistrate. This position is actually not suitable for him. Du Zhongxiao is more suitable for being a landlord official, who can make the decision by himself, plan the development of the local area, and make rational use of manpower and financial resources. The problem is his current status and he has no right to choose. Xia La values ​​himself and is deemed to be a signing of the judge. The opportunity cannot be missed. He knows that being busy is Xia La's achievements, but he still cannot stop for a moment.

The grass next to it has sprouted, and the willow trees by the river are exposed in goose yellow. Spring has come unknowingly.

Du Zhongxiao looked at the surrounding mountains, mostly bare and a little ugly. Due to years of iron smelting, cutting trees and burning charcoal, the trees on the mountain had long been cut down. It is now that coal smelting iron is popular, and some small trees have grown.
