With the huge sale of soap, I made a lot of money and could not be satisfied with things like soap. I took out part of the money and put it in the academy for development, part of it to improve the living conditions of the academy students, and part of it to consume materials for research and development.

At that time, the envoy of the Three Divisions was Cai Xiang, and the Ordnance Supervisor was under the jurisdiction of the Three Divisions. Han Qi allowed it and Cai Xiang cooperated to transfer some officials assigned to the Ordnance Supervisor. They studied the study of Investigation of Things and entered the academy for further studies. The court also selected some candidates to enter, so that more than 80 people could study Investigation of Things.

More than 30 of them have been studying for a while and have a certain foundation. In addition, Zheng Lang was the leader, and he taught R&D, so he developed many things, such as the further industrialization of ethanol. With the advent of real industrial alcohol, another thing also appeared, perfume. The Song Dynasty infused clothes with fragrance, but was there any perfume useful? After spraying, the cost was low, the fragrance was stronger, and it could be replaced at any time. There were also shower gels and shampoos, which appeared together.

As these things emerged and semi-industrialization emerged, the profits of the workshop increased, and the workers in it gradually reached nearly 700, becoming a super large workshop. It also used slag ash, lime and gypsum to synthesize cement into earth, which was a little expensive, but it was also the real launch of cement.

With the support of money and silk, Zheng Lang led a group of students to overcome some important technical difficulties. First, iron smelting technology was too advanced to achieve, but some Ming and Qing technologies were adopted. For example, improving the bellows, developing piston blowers, coking coal, trialing blast furnaces, and evolving crucible iron smelting methods.

This is iron, not steel. The steelmaking method in the Song Dynasty had appeared, and it was still relatively backward. It was improved during the Ming and Qing dynasties. When filling steel, it was sealed with mud, and when stir-frying steel, it was covered with straw sandals. Second, it was calcined with pig iron and cooked iron. Workers kept stir-frying, which was called the steel-frying method. This is the main principle of steelmaking method in later generations, but it was improved more scientific and advanced. In addition, during production, the iron of the pig iron furnace was directly injected into the stir-frying furnace, and the iron was frying into steel, saving the cost of steelmaking.

There is also the Su steel method, not the Soviet steel method, but a new steelmaking method from Nanjing and Wuhu in the Ming Dynasty. After craftsmen melted the pig iron in the furnace, dripped it onto the cooked iron to merge and become steel. However, the technical requirements are higher. There is also the stewing steel method, which puts the cooked iron, a small amount of charcoal powder, bone powder, and a few catalytic substances into a sealed tank, and keep it in heat for ten hours to increase the steel content and strength of some proficient steel.

The casting technology and forging technology were improved, and the smelting of cypress was developed. In the past, the melting temperature of cypress ore exceeded the gasification temperature of zinc, and smelting was very difficult. During the Song Dynasty, some brass products had appeared, but they were still very backward. Zheng Lang used the Ming Dynasty's smelting technology to smel.

None of them succeeded because they just started.

If it weren't for Zhengzhou Dingyou this time, Zheng Lang wouldn't have time to consider these. If there were no income from that workshop, there would be no capital to develop these. The ordnance surveillance is mainly based on weapons, not for the people's livelihood.

But as Zheng Lang thought more and more, he paid more attention to morality. He not only said it, but also took the lead in doing it. So he had this Emperor's Charity Association, an inappropriate name. However, when he thought about it carefully, he would understand that Zheng Lang's good intentions were actually the Red Cross Society.
