When my father reported some ideas to Li Er for consideration, Yang Heng had already divided it into three parts and started working.

Part of them are a group of construction teams led by the uncles. Of course, this group of construction teams has attracted some farmers. Each of them has a labor force and starts digging the foundation first, and even goes to the mountains to find some stones to lay the foundation. This matter is more difficult now. Without explosives, they need to work completely by hand. Fortunately, Yang Heng built some chisels and wedges a long time ago. This is relatively simple. However, when large stones are encountered, they still need to set up fire and pour cold water. This can disintegrate a stone as quickly as possible, but in the end, it still requires chisels and wedges to be used.

Another part is that Feng Bo led a few people to start digging the mud pond. This requires Yang Heng to demonstrate, otherwise these farmers would not dare to go forward to dig the mud pond into the mud pond.

"Everyone is optimistic. We will first get away from this place and then throw a few torches over. Look, aren't it? We can call it biogas, that is, gases in the swamp, which can be used to burn. After a while, I will make my own biogas. I can use biogas when I light the lamp at home and cook."

While waiting for the flames ahead to go out, Yang Heng explained by the way that he did not explain any profound knowledge, but just told everyone what this is.

"Okay, now the biogas emitted from it has been burned out. It will take some time to produce it again. In this way, we have to take out part of the mud inside as quickly as possible, but don't dry for a long time. Once you find that there are more bubbles in the middle, you will have to leave. Also, Feng Bo, you can take someone to block the leaves around and don't let the leaves fall into this mud pond."

As he spoke, Yang Heng personally brought a shovel to the edge of the mud pond and shoveled a few shovels of mud. "Look, I'm fine, right?" "Yes, we have nothing to do." Not only Yang Heng went over, but Dandan also took a few older children and shoveled a few shovels of mud out.

"Okay, everyone, you guys, you see that Xiao Langjun is okay, so we are naturally even more okay. You should know that Xiao Langjun is a noble person, what are we bitches?" Someone shouted, and after Brother Yang Heng and others' demonstrations, they believed it.

"Okay, let's do it too." There are not many people, but only a few people, and there are a few women in it. I am grateful to the host for letting them have land to grow and eat, so they will naturally work hard.

"Okay, Boss Feng, but you have to pay attention to the time. If there are too many bubbles, you have to leave and burn the bubbles before drying." "If you understand Xiao Langjun, you can do your business with confidence."

Next is what Yang Heng has to do, that is, the issue of manufacturing biogas. To create biogas, there is a biogas tank. However, at this time, Yang Heng did not have any cement and it was too late to burn it. In addition, there was no coal mine, mainly open-pit coal mines. What should I do if there is no cement? Then I can only find another way.

What is the solution? Use glutinous rice soup and beside the loess and mud. When the building is dry, it is even stronger than cement. It is a bit waste of food. Fortunately, one year, Yang Heng's family and uncles planted a batch of glutinous rice, which is now used. The meal list for this period was also released, such as dry glutinous rice, glutinous rice cakes, etc. In fact, the purpose is to avoid people picking out opinions. Eat at home every day, please care how much I eat, but don't make glutinous rice every day. I haven't heard of eating glutinous rice, that's not good. I'm sure there is a story at first glance. At this time, the food in the country is not very sufficient, especially after a large-scale slight locust plague. Although there is no end to the production, it is not a normal year.

Yang Heng did not ask for any helpers when making the biogas pool. Instead, he led a group of younger brothers and sisters to do it themselves. He just temporarily invited his uncle to be a consultant. He asked his uncle to do some things like building walls. Don't think that his uncle is a carpenter, but in the past few years, his bricklayer has achieved some success, and other uncles' carpenters have also achieved some success.

The biogas matter is not too urgent. The main reason is that Yang Heng is still looking for a copper smith, a copper smith who can make copper tubes. Although Yang Heng knows a blacksmith, it is still impossible to ask him to make some finer copper tubes.

Wherever you want to find a copper smith, you naturally have to go to the market. Perhaps there will be some technical slaves in the market. Yang Heng arranged for one of his uncles to go to the city with the housekeeper. Moreover, Yang Heng was not limited to choosing copper smiths, but also some other jobs. As long as it is available in the market or where it can be hired, it must be hired. Now Yang Heng's scene has begun to slowly spread out, and his second goal has been achieved.

His first goal was to survive, and he had already achieved it. Since he had a hundred acres of barren land in the mountains, he survived. The second step was to make his father promising. Now that his father has become a fourth-rank official, he naturally believed that the second step was completed. The next step was to develop well in the Tang Dynasty and try to use some of the technologies from later generations to seek benefits. The next goal is, and it is a long-term goal.

Without the copper smith, Yang Heng led his younger brothers and sisters to slowly make the pool of the biogas pool. "Brother Heng, are you talking about it? Can such a pool really make it produce the kind of gas that burns and emit blue light, even brighter than the sun at night." The little girl asked curiously without saying a word. In fact, she didn't believe in Yang Heng, but she had never understood the chemical principles that Yang Heng said. This was a shameful thing for the little girl.

"Don't ask, when did Brother Heng deceive us? You can't understand it, ah, our little genius is finally stumped again. I want to remember it carefully. I will remember that in July of the second year of Zhenguan in the Tang Dynasty, Xiao Niang, that is, sister Yang Shu, there are things that I can't do, and I show a lot of disconfidence." "Stir, stupid, you are bad, you are bad, I want to tell my parents, saying that you bully your lovely sister, I will let them beat you."
