"Nephew, I suddenly thought of a question. You said you should use an iron shaft." The uncle woke up and naturally asked questions.

"Yes, uncle, is there any problem? Can iron shafts be worn-resistant? Can wooden shafts withstand the weight of such a large water truck?" Yang Heng was also puzzled. How could his uncle ask such a question?

"But the iron shaft is very heavy when it turns, and it is not what you said to be wear-resistant. I have tried it on a carriage." This uncle seems to have a story, otherwise he would not have such good woodworking skills.

"Ah, wear-resistant, wear-resistant, uncle, don't you use lubricant?" "Lutrient oil, what is that?" uncle was even more puzzled. "Oh..." Yang Heng slapped his head. This is Datang. Lubricant, there is no such thing as Datang. Maybe some cooking oil can be used instead, and vegetable oil can be used on the low-speed shaft.

"Then, uncle, is there any oil for us to cook?" Yang Heng really doesn't remember. He has never used oil to cook during this period. By the way, when he thought of cooking oil, he also needed to make a bite of the iron pan.

"Easy to cook, my nephew, do you think we are? Even the big families in the city can not use cooking oil. At most, when eating meat, we use fat fat to make some animal oil for use. Only those real families can eat some sesame oil." "Sew oil, uncle, you mean that only sesame oil is not enough now." "Yes, rich people eat sesame oil, and poor people eat animal oil, and poor people can stutter, so what else can they eat." My uncle's idea is undesirable, but perhaps, the entire history of China can be continued with the younger uncle's obedience to the people. Although there were many peasant uprisings in history, no one has ever succeeded. Perhaps Zhu Hongwu, who was later born, was half a grassroots background.

Yang Heng found that there were many things that happened recently, which was not a good phenomenon. It was better to consider some things in detail. Otherwise, it would be not a good thing to become a pure angry young man. You must know that this world needs to be saved. After that, after that, it has passed, and it has been said a little bit. If you save the world, Yang Heng cannot choose to take care of his small shoulders.

The first thing I think about is about cooking oil. Since the vegetable oil is only sesame oil at this time, maybe rapeseed oil is a choice. But if there is rapeseed at this time, maybe you can choose soybean oil first. Although Yang Heng didn’t like soybean oil in his previous life, he liked peanut oil, but he didn’t know where the peanuts were growing at this time. Maybe he should go out to make friends with some businessmen, maybe they will surprise Yang Heng.

"Uncle, have you heard of soybean oil?" "Soybean oil, nephew, what did you say? I haven't heard of any soybean oil." "Haha, that's good, by the way, uncle, who can make some stone tools, like grinders." Yang Heng first thought of oil pressing. Although he didn't know how to press soybean oil, he had seen peanut oil pressing. He didn't understand other methods of oil pressing. In his previous life, he was not an oil pressing worker.

"Yes, yes, your second uncle can make mills. You must know that the mills in the village are all made by your second uncle." Sure enough, the people of this era are still versatile, but their brains are a bit rigid and they don't know how to use them. But Yang Heng didn't think about it. He was a time traveler. In the era of knowledge explosion in his previous life, he naturally had a great vision. This cannot be said to have strong innovation ability, otherwise he would not have traveled to this era. You must know that a successful person would not do such a fool like traveling through time. Although this time travel is not controlled by himself, those successful people are very cautious. His life is well protected, so naturally there will be no time traveling through time. First of all, they will not take their lives seriously, and secondly, they will not appear in some dangerous places. However, if they travel through time in their sleep, they cannot be said to be regretful.

Without spiral pressure, we had to use a lever to press the pressure. Uncle Er made a millstone with a diameter of 60 cm according to Yang Heng's requirements, and also made another part of a millstone pressing soybean oil matching the millstone. Such a set of pressing tools were made. Although the stone tools were not very useful, Yang Heng could not find too much iron to make this kind of pressing oil tools. Soybeans would be wasted some.

If you want to waste, it is actually not much waste. So the bean cakes after pressing oil can also be made into tofu. In this poor era, it is considered a luxury to eat a bite of tofu made from bean cakes. Not to mention that this bean cake is not the kind of food that comes with various additives and cannot survive in bacteria. No matter how you eat it, you will not eat it. You will not be unhealthy. It is just that the taste is a bit bad. Even though later generations know that those foods are poisonous, not many people say they will not eat it. If this one is poisonous and that one is poisonous, then they will only starve to death, or learn to live by drinking wind, but is the wind safe?

"It's oily, it's oily. My nephew is so awesome. Just use two stones to press the oil out." The uncles shouted happily, while the father and mother were holding their happiness there without saying anything. Be reserved, be reserved, okay?

"Ah, no, I can't hold it anymore. My son is the most powerful. He has been secretly learning outside the school for a long time." I finally couldn't hold it anymore. My son was outstanding, so she was naturally very happy on her face. You can't just let others praise you instead of praise yourself.

"What did you say? Sister-in-law and nephew still recognize the word. Sister-in-law, do you think your nephew in our family also let Nephew Heng teach you?" "Yes, yes, sister-in-law and my child, you must not teach you." "Okay, okay, don't tell me, go and discuss with your nephew, he has the final say." My mother decided at this time that she should hand over this family to Yang Heng immediately and let Yang Heng take charge of the house, see the construction of the house, the cultivation of the desert, and even the water truck that will be made soon. These all show that Yang Heng is the leader. It seems that she can only enjoy her happiness in the future. By the way, there is also the secret recipe for bathing. She will tell her immediately. Before the child gets married, she will just hand over the inheritance in advance.
