Quick wear: She has turned over the big guys from all walks of life

In the next two days, Mingyi fumbled and failed three times. The liquid boiled for the fourth time solidified in the grinding tool and formed the shape of a brick.

The Cheng Mingyi brothers gathered around her and poked her happily.

"Yiyi, what is this?"

"Soap, for laundry use." Mingyi cut the edge of the solid soap with a knife, loosened it, poured it out and handed it to them, "You go and wash clothes and try to see if it works."

"Okay, let's go right away."

Before Cheng Mingyi reached out to take it, Cheng Mingxin took it first. The young man was in good spirits and turned around to find his own dirty clothes.

"I'll go take a look too." After Cheng Mingyi finished speaking, he followed closely behind.

The others didn't want to go, so they followed Cheng Mingyi and ran away.

Mingyi looked at their backs, chuckled and called to her brother, "Let's come out together. This batch has been made for five yuan, which is enough for one room at home."

"Aren't you going to give it to Prince Zhou?" Cheng Mingli helped him out. The four pieces of soap with a light yellow color looked very good.

There is no modern technology or harsh work, and it will not hurt your hands when used.

"We won't give it away for now. Let's try it out for a few days." Soap is a good thing. Nowadays, people use soap locust or plant ash to wash clothes.

Common people mostly use plant ashes, and those who live a better life use soap locust; while aristocrats from aristocratic families use soap locust to make powder for laundry, which is also easy to use.

However, if she studies further and adds saponin to the soap, the effect will definitely be better, but she doesn’t know if saponin is available in the northwest.

Half an hour later, Cheng Mingyi and others returned with joy. Cheng Mingxin was dancing and squandering the soap.

Mingyi visually inspected the soap and found that it was half the size.

Good guy, no wonder it took them so long to go there. How long did they take to wash? Or how many clothes were washed?

"Yiyi, the soap you mentioned is very easy to use. Serious stains can be washed away by washing them twice more. For more serious stains, you need to wash them for a longer time. Although it cannot completely remove them, it can lighten the color."

Cheng Mingyi made a very pertinent comment when he opened his mouth.

Mingyi nodded, "I don't know if there are saponins in our area. It would be better if there are saponins."

"Soapwood!" Cheng Minglian thought thoughtfully.

Cheng Mingli's eyes moved slightly and asked, "Have you seen my third cousin?"

"I've seen it before. It seems to be in the mountains in the south. Once I went there to look for firewood and saw a saponaria tree. It was a big one, and there were some small trees next to it that also had saponica trees."

"Third cousin, take me to see when the snow melts." Mingyi suddenly beamed.

"Okay! If there's anything I can't do, I'll take you there when the snow melts." Cheng Minglian smiled and narrowed his eyes. At least he is useful.

Among the several brothers and sisters, the older ones are always inferior to the two younger ones. Who doesn’t have some complicated emotions in his heart? It was too late for him to be happy that he could help.

After settling an undecided matter in her mind, Mingyi had a soft smile on her face.

"First cousin, second cousin, third cousin, fourth cousin, do you think our soap can be sold?"

"Yes, it definitely can!" Cheng Mingyi said with full determination, "How can no one want such a useful soap? How should the price be determined?"

Mingyi silently calculated the cost of the soap, but there was no other cost except lard oil; the molds could be made at home, and there were plenty of plant ash at home. Without livestock, the plant ash would be useless.

I just do laundry on weekdays, so I won’t use it up at all.

"It's ten cents a piece. Let's make a batch and sell them out," Mingyi said.

Cheng Mingyi asked puzzledly, "Can't you make some first and sell them?" "Yes, it is possible, but our soap has no technical content. If someone is interested in research, it can be easily developed; therefore, this time the soap may only be sold Several times, the number must be large.”

Don't underestimate the wisdom of the ancients.

Cheng Minglian said uncertainly.

"It shouldn't be possible, right? If you don't do it, we won't know."

Cheng Mingzhi said: "Just as Yiyi said, Yiyi's thinking is right. If we can't figure it out, others can't figure it out either?"

Cheng Mingxin nodded, acknowledging his brother's words.

"Then let's go and make molds. If you want to make more, you can't have less molds. There is also the problem of pig suet that needs to be solved." Once the idea came into play, Cheng Mingyi quickly figured out the way.

Mingyi nodded, "Leave this matter to my father, eldest uncle, and second uncle."

"Okay, let's make the mold first. Yiyi and Mingli tell my father, uncle, and third uncle to buy the pork suet as soon as possible. The pork suet needs to be boiled before it can be used."

The four cousins ​​walked away arm in arm. Cheng Mingli and Mingyi took the remaining four yuan to find their biological father.

When they found him, his father and grandfather were talking together, but they didn't see his eldest and second uncle.

"Dad, grandpa."

The two walked forward and called people.

Cheng Dazhu nodded and smiled kindly, "You are here, are you cold? I see your little faces are red from the cold."

"It's not very cold." Mingyi walked forward holding the soap, "Grandpa, dad, you see, this is the soap we made; it is very useful for washing clothes and washing hands."

"This" Cheng Dazhu reached out and touched it uncertainly. It felt a little greasy, but more of a smooth feeling. "Have you used it?"

Mingyi nodded, "My cousin and the others have used it before. Clothes that are not seriously stained will come clean in just one wash; clothes that are seriously stained will need to be washed for a longer time. Compared to the plant ash we use, it is much easier to use."

"That's really good." Ding Ding stared at the soap. After a moment, he looked up at Ming Yi and said, "Is this what you plan to make and sell?"

"Well, the price is ten cents a piece. This thing is fresh; let's make more and sell it for four to five thousand yuan at a time."

Cheng Mingli added: "My sister said that soap production can be quickly figured out by others who are willing to study it. Therefore, if you make more at a time and sell it, you can earn more money."

Cheng Dazhu looked at Mingyi with a mixture of relief, love and excitement.

"Okay, good children, they are all good children; I will ask your parents to help you. Don't be afraid whether you make money or not. Go ahead and do it boldly." Cheng Dazhu briefly calculated the materials needed for Mingyi. So far, he has only asked The third child bought pork suet.

The half of the pork suet has not been used up after two days of use.

A piece of pork suet costs about one hundred yuan. If it is made and sold, the profit is very considerable.

"Do you have enough pork suet?" Cheng Dazhu asked again.

Mingyi shook his head, "If you want to make it in large quantities, you will need more suet."

"Is it enough to ask your father and the others to buy three more pairs?"

"I don't know, I can only take a look." She can't give a clear answer. If she is too clear, she will be exposed more; she is just smart enough now, and her elders have to support her for some things.

Cheng Dazhu slapped his forehead and suddenly realized, "I took it for granted, so let's buy three pairs of pork suet first. Third brother, ask your eldest brother and second brother to go to Fucheng with you to find pork suet."

The second update is in place, go to sleep~~Good night, babies
