'Finally, it's back. After inspecting the glass workshop, Li Chen was finally able to breathe a sigh of relief. At noon he ate at the coal stove workshop. After eating, I went to the glass workshop and went around before coming back.

What he is holding in his hand is the latest product of the glass workshop, the glass mirror. This mirror is not big, but it is the size of a palm, and this is a prototype. Li Chen expects to sell this at the next auction.

To make a glass mirror, it is not difficult. If you really want Li Chen's parents to do it, it is estimated that it will be enough. But he has a lot of hired workers, so he doesn't have to do it himself, just open his mouth.

It's easy to open your mouth, Li Chen asked the craftsman to stick the tin foil on the back of the glass, and then poured mercury on it. Mercury will react with the tin, and the tin foil will be firmly embedded in the surface of the glass, and a mirror will be completed. But it's not entirely without problems.

Because mercury is poisonous. It's also very toxic. Very poisonous, and easily poisoned. Mercury is easily absorbed by the body. In this regard, Li Chen had no choice but to control the production of glass mirrors, anyway, he had no intention of selling such a luxury as glass like garbage in a short period of time.

In addition, it is strongly required to be made on another ventilated occasion, and workers will never be touched. Then the workers who made the glass mirror had to drink mung beans and eat pig's blood every day, and drink tea to detoxify. He is not the kind of capitalist who has no conscience and disregards people's lives.

'Uncle, you're back. After entering the outer gate, Li Chen led the horse to the stable, and immediately a servant stepped forward to take care of the horse. Then I entered the main entrance, where several children were in physical education class and doing simple physical activities. Seeing Li Chen coming back, they greeted each other.

Physical education class, of course, will not be like modern physical education class and physical education teacher. There are not enough teacher resources, and of course it is impossible to get a special physical education teacher to come out. Therefore, they are free to move, as long as they do not fight, do not engage in dangerous activities, they are allowed to graze their sheep.

Li Chen told the child a few words to pay attention to safety, and then continued to walk, he planned to go back to his room, but he didn't pay attention, as soon as he left, several children hurriedly turned around and rushed into the house from somewhere else. As a result, before Li Chen could return to the room, he was intercepted.

'You're back, just in time, and I've got a couple of arithmetic questions for you. Before Li Chen could go back to the house to rest, he was caught by Luo Qing, and he pulled Li Chen to a place.

'Slow down, slow down, I have a problem too. Answer me first. Before Luo Qing could leave in a hurry, Gundam also ran over, "My question is more urgent, answer me first." Luo Qing glared at him and said unhappily.

'Just kidding, aren't you in a hurry when your question is urgent?' Gouda glared unhappily, "Isn't your little problem just a matter of knowledge?" I'll help you with your research another day. ’

'Another day, another day. Huang Tiansheng, who didn't seem to be messy enough, also came, "You said the same thing last time, no, I have to solve my problem first today." ’

Li Chen was helpless, and Luo Yin had a few friends who came and helped him a lot. Like arithmetic, he doesn't have to take classes in person now, he only needs to teach Luo Qinghe Yixin, and they can teach it to other children. Let him save a lot of effort.

There are many others, such as physics, which can be handed over to Gundam, obsessed with tricks to get Gundam, and there is also research on physics. And Huang Tiansheng, in addition to being proficient in astronomy, actually understands geography. Pingdao people, because of the Taoist alchemy, are more specialized in chemistry. With them, Li Chen is a lot more relaxed, and he no longer has to teach everything by himself like before.

It's just that while some of his troubles have been solved, more troubles have been added. Because they are all specialized in a certain area, like modern scientists, many scientists have problems with them.

What's the problem? It's more real. In order to attract them over, Li Chen threw out some things, such as arithmetic, in addition to Arabic numerals, there were also some simplified simultaneous equation operations, and he also threw out a lot of mathematical formulas that he remembered.

The problem is that he doesn't understand a lot of things. Modern education, at least Chinese education, it would be good if mathematics could be used, who would teach you the principles.

It's not that there isn't a principle, but who will learn it? It's like mathematics, it's good to know what formula to use to solve a problem, who will memorize it, how to derive the formula? That's something that only mathematicians or math students do.

As a result, just like the famous saying, if you don't die, you won't die, Li Chen, who was dead, threw out a lot of things that they were interested in and attracted them to come over, but Luo Qing and others, who were more serious, pestered him all day long, asking how those things were confirmed.

Like when he handed over the formula to the Pingdao people Mohr concentration, the Pingdao people kept pestering and asking how to confirm and deduce. It almost drove him crazy. As he does now, his traces must have been betrayed by several students. This person has studied well for three years and three days for bad, and several of their teachers are now very good at using grades to motivate students.

And the reason why he didn't hide his traces was because he thought that they were all in class now, probably no problem, but they left the class and ran over, intercepted him before he went back to his room, and then started another round of quarrels.

Forget it, I admit it. Li Chen was going to rest, but now he can't rest, "Don't make any noise." With a roar, the world was cleared, 'Half an hour for each person, now begin in first-come, first-served order.' ’

'Well, Heng, you are not allowed to have an opinion, and you don't have an opinion for half an hour. Half an hour is an hour, Li Chen feels that life will be worse than death in the next three hours, and discussing the problem of brain-burning derivation with these guys will kill a lot of brain cells.

'I'm going to go around in circles, how nice it would be if I was surrounded by girls, why are there a bunch of men.' Li Chen resigned himself to his fate and began to discuss with Luo Qing, and while coping with it, he was distracted by it.

'Crack, crack. In the sound of firecrackers, Li Chen came to Yangzhou to get his first industry, and the sauna opened. Wait, rewind. It should be the sound of firecrackers, Li Chen's Nth industry in Yangzhou, sauna, opened.

Li Chen suffered for two days, and finally, waited for the sauna to open. At this opening, Li Chen chose to keep a low profile and did not make a big fanfare. The water in Yangzhou is too deep, he is just a little shrimp, and he doesn't want to provoke anything. Therefore, it is best to be low-key and festive to open.

said that it was a low-key opening, but in fact, there were many people. Everyone Li Chen knew came, Zhao Duanduan brought a pair of sisters, Su Laiman got a businessman friend, Su Xiaoxiao also brought a few sisters Tao, Qin Fengde brothers and some rangers. Luo Yinde has several brothers, and some of them are good friends, and they all came to cheer.

In the curious eyes of everyone, Datang, and even the world's first sauna, opened. (To be continued.) )
