After breakfast, Liu Yi told his uncle that he was about to leave in the morning. After hearing this, his uncle and aunt kept trying to stay and said that Liu Yi had just resigned and that he would stay in his hometown for a while. He would take a break from it.

Liu Yi said to them, "I went out this time. Some things I hadn't handed over when I was working. Maybe I'll go back to the countryside after I finish my work. I'll stay for a few more days at that time." I thought to myself, if the experiment is successful, I'll be in the countryside for the rest of my life.

I bid farewell to my uncle and my family and returned to my home in the town. The home in Liuyi Town is the top floor of the building. When I first decorated, my parents missed the feeling of farming. So I picked a lot of soil on the top floor and surrounded it with bricks. It was more than ten square meters. The soil layer inside was one foot thick. It was enough to grow some green onions and side dishes. But since the vegetable garden was built, it was deserted after growing vegetables. Naturally, the reason was that the whole family was busy making a living outside and had no time to go home, let alone growing vegetables on the roof.

Liu Yi valued this piece of land and was preparing to experiment with the cultivation method and the effect of "special fertilizers" in the "Shennong Jing" on the top floor. There is also an advantage here that no one will come up at all, and even if the experiment results are shocking, it will not attract too much attention. Pull out the free weeds growing in the vegetable garden, and loosen the soil inside. More than ten square meters of land will not take long to finish the work here, and the matter will come to an end.

In addition to getting the raw materials of "special fertilizers", Liu Yi also thought about how to "refined" the raw materials. Because this was just a small batch experiment, there were not many props. Finally, Liu Yi thought about it and moved the two stone pounds that originally opened the noodle restaurant, and prepared them to pound the slag into fine powder. He just didn't know if it would work. Anyway, he was preparing and thinking about it.

In addition, you have to heat up the ore and go to the blacksmith shop. Luoshi Town is an old town. There is also an iron shop on the town. Now there are only hoes and mowing knives there, barely maintaining it. However, looking at the person who took out the iron bars and the hammers were flying and the muscles were strong and powerful, you would never believe that he would be an old man who was already seventy years old.

According to him, ironwork is just his hobby now. He has been playing iron all his life, and he is not used to it when he is not active in his body and does something. His children are all promising. He asked him to move to the tall buildings in the city several times to live with them, but he refused.

Liu Yi explained his purpose and said he wanted to get an iron can, and wanted the old man to help him beat one. The old blacksmith understood what Liu Yi meant, but hesitated: "I haven't made those things for a long time now, and my skills are unfamiliar." He didn't say he couldn't do it, but he refused.

After thinking about it, I thought: "I remember there seems to be one in my house, which is that there is already rust on the outside, and that is the jar used to simmer soup, and even the lid."

"I originally had no hope when I heard what he meant, but in the end I threw out a life-saving straw." Liu Yi's heart was like a roller coaster, with high and low fluctuations, and his heart was not a little fainted. Anyway, it was not used for food, as long as it could be used. I agreed quickly.

The old man was not far from the shop, so he went back in a while and handed it to Liu Yi, without asking him what he used for: "Look, can it be used?"

I looked at the iron can, and there was indeed a thick layer of rust on the outside. There might be a lid to cover the mouth of the can tightly, and the inside looked pretty good. Asked: "Old man, how much do you think of this thing?"

"If you don't have any money, just take it. I didn't expect it would be useful after leaving it for so long. I'll take it away with you."

Well, when I bought an iron can, I didn’t expect to meet such an easy-to-talk old man. Liu Yi still felt a little guilty. Seeing that the old man’s index finger and middle finger were burnt, he went to the shop next to him to buy two packs of cigarettes worth ten yuan. "Uncle, I’m not polite to you. I took your can. These two packs of cigarettes are not expensive, so I just want to say what do you think?"

The old man looked at Liu Yi: "I didn't expect that you are interesting. Haha, I have accepted the cigarettes and I will use the iron guy in the future. When I tell me, don't look at me, I only have an iron shop, many of the apprentices I brought out work in the steel factory." The old man said proudly.

"Okay, I will definitely come to you if you have something to do." Liu Yi picked up the iron can and walked home carelessly.

On the way back, Liu Yi bought a lot of things, a gas stove, a gas tank, and a brush, and prepared to make a little rusty iron can. Everything was ready and everything was ready, but the raw materials were missing.

I stayed at home for another day. In the afternoon, my cousin Qian Jun called and said that everything was ready and that he would drive back tomorrow morning and call Liu Yi when he arrived.

I waited anxiously for another day. The next morning, Liu Yi took the bus to the intersection of the expressway. When he called, Qian Jun's cousin-law also set off. If he drove by himself, he would actually only take two hours to get from Zunyi, Guizhou to Shancheng.

But it would be more troublesome if Liu Yi went to take a long-distance bus. The bus set a departure time every day. It had to be a long-distance bus that had been driven from Luoshi Town, and Liu Yi had to run to the city to get on. Thinking about things in his mind, time flies quickly, and if you are bored, you can use your phone to pass it. I didn't feel that I had been waiting for a long time. Qian Junda's cousin told him that it was almost here. Liu Yi raised his spirit, but don't miss it. He recalled the license plate number of his pickup truck, which was easier to remember. After a while, he saw the figure of the pickup truck, and quickly reached the side of the road to wave his arm to indicate. My cousin also saw Liu Yi, and the car slowly stopped to the side.

"Why are you here? Just tell me a place and I'll send it to you." My cousin said politely.

"It's all right here, I've agreed with my friend. Just ask him to arrange the car to come and get it directly." In order to prevent my cousin from being suspicious, Liu Yi lied to his cousin.

"That's it, that's OK. I'll leave in advance." I came back from Zunyi from afar, and there must be something wrong. After saying that, I drove away.

Liu Yi didn't take the bus back. He had just gotten so much ore, and they were packed in woven pockets. After a closer look, there were six packs in total, and they were carried by hand, each pack of 10 or 20 kilograms. He picked up a tricycle and asked him to take goods downstairs of the town's house. He gave the car money. After moving it back and forth several times, he finally moved all the ore to the roof.

Everything was ready. Liu Yi connected the gas tank that was brought up with the ore and the gas stove first with the gas pipe. He tried to fire a few times, so why didn't it burn? Damn, I forgot to open the gas valve of the gas tank. I was dizzy, so I patted my head and opened the gas valve. After firing a few times, I succeeded.

Liu Yi also cleaned the iron cans he bought with a wire brush. Anyway, they looked much more pleasing. Thinking about the steps described in the books, looking at so many ores, God, he can't get so much.

I just picked up a few pieces and put them in a lot of iron jars together. The vegetable garden we tested was not very big. This time, it was made by hand, so just a little less. What I don’t care much about is the result. Based on the content written in the Wuming Old Taoist’s book, I carefully checked the ore name, and then put it into the iron pipe one by one according to the ratio. When I saw it, it seemed that it was still bad, and it was ash.

Modern people know that wood ash is originally a farm fertilizer, and its main ingredient is potassium carbonate. Potassium carbonate is a strong alkali and weak acid salt, which hydrolyzes in water to produce OH-ions. Wood ash is a farm potassium fertilizer widely used in rural areas. The main ingredient of wood ash is potassium, an organic fertilizer rich in potassium, calcium and phosphorus, and also contains a small amount of trace elements such as boron, aluminum, and manganese.

There is no such thing as the town. There is no way, Liu Yi had to go to the outskirts of the town to grab a few handfuls of straw from a farmer. Fortunately, this thing is not valuable and there are everywhere in the countryside. The farmers didn't care about it and asked him if it was enough? I won't say much. Anyway, it's a step-by-step process. It takes two hours to heat it. Turn on the gas stove and control the fire to low heat. (I haven't heard of martial arts and medicine, haha). Add an appropriate amount of water to it, so I don't have to worry about it.

Two hours have come. Liu Yi, who had time to go out and had a walk around, returned to the roof on time. It turned out that there was a door on the roof. Now Liu Yi has added a lock, so he is not afraid of anyone coming up.

I opened the lid of the iron can with full expectation, and a stream of hot air came out. There was a smell that couldn't be said. It was so stimulating that it was not considered good. Do you believe it if you said it was good? Turn off the fire quickly to prevent the smell from spreading too far if it continues to heat up, and it would be bad to attract others' attention. Then wait for it to cool down.

Liu Yi took the stone pounding that had been prepared in advance and tried the temperature of the ore in the iron pipe. It was no longer hot and he didn't care. He poured it into the groove of the stone pounding. There was a little too much, and he made some more. It seemed that it would be fine only if it was pounded twice. Just pound it. Liu Yi lifted the stone pounding rod and pounded it one by one. The ore was still very hard. After rushing hard for half an hour, it seemed that no result was achieved, and the ore broke a few pieces. This was not possible. Liu Yi thought to himself, but he couldn't think of a good idea after thinking about it.

Depressed, he had to go out to vent his depression, otherwise he would feel frustrated when he saw the ore piled up there. He walked and stopped and looked at the black bean flower restaurant on the street. It was a very distinctive bean flower restaurant, which was very famous in Luoshi Town. Occasionally, Liu Yi's family also entertained guests here. The toan flower here is made of mechanically, but made by stone mills, so the taste is unique.

As he thought about it, Liu Yi felt that he had found a key place, making machinery. "Haha" laughed wildly in his heart, and it was really good to go out for a walk. If the ore is not handmade, use a stone crusher. If you think the particles are large, you can also use a grinder. When Liu Yi was working and selling, he participated in a comprehensive motorcycle and machine exhibition at the exhibition venue. There is also a market for selling such machinery in Shancheng.

It is better to act than to act, just do it. Liu Yi went straight to the mechanical market without saying a word. If what the book said was true, it would be used in the future. Even if it was not effective, it would not cost much money. It should be a fight for his own destiny.

Waiting for follow-up...
