Over the next two days, Mingyi groped and failed three times, and the fourth boiled liquid solidified in the abrasive to form the shape of a brick.

Cheng Mingyi's brothers gathered around her, and happily stretched out their hands and poked.

"Yiyi, what is this?"

"Soap, laundry." Mingyi cut the edge of the solid soap with a knife, poured it out and handed it to them after loosening it, "You guys go wash your clothes and see if it works." ”

"Come on, I'll go right away."

Without waiting for Cheng Mingyi to reach out to take it, Cheng Mingxin took it first, and the young man was in good spirits, so he turned around and ran to find his own dirty clothes.

"I'll check it out too." After Cheng Mingyi finished speaking, he strode closely behind.

The other people didn't want to go, so they ran away with Cheng Mingyi.

Mingyi looked at their backs, chuckled and called out to his brother, "Come out together, this batch has been successfully made for five yuan, and one room in the house is just enough." ”

"You don't send it to the prince of Zhou?" Cheng Mingli helped him get up, and the four pieces of soap with a pale yellow glow looked very good.

Without modern technology and hard work, it won't hurt your hands if you use it.

"I won't send it for the time being, let's try it for a few days." Soap is a good thing, and nowadays people use soap horn or plant ash to wash clothes.

Most of the common people use plant ash, and those who live better use soap horn; And the nobles of the family have a powder that is specially used to make laundry from soap horn, which is also easy to use.

However, when she studied it again, she added soap horn to the soap; The effect must be better, but I don't know if there is such a thing as soaphorn in the northwest.

Half an hour later, Cheng Mingyi and others returned with cheers, and Cheng Mingxin squandered soap with his hands.

Mingyi visually inspected the soap and was half smaller.

Good guys, no wonder they went for so long, how long did they wash? Or how much laundry was washed?

"Yiyi, the soap you said is very useful, and the more serious dirt can be washed off by washing it twice; If it is more serious, it should be washed for a longer time, although it cannot be completely cleaned, but it can wash the color a little lighter. ”

Cheng Mingyi's opening is a very pertinent evaluation.

Mingyi nodded, "I don't know if we have soap horns in this piece, it would be better if there were soap horns." ”

"Soaphorn!" Cheng Minglian was thoughtful.

Cheng Mingli's eyes moved slightly, and he asked, "Third cousin has seen it?" ”

"Yes, it seems that in the mountains to the south, once I went there to look for Chai He and saw a soaphorn tree; It's a big one, and there are some small trees next to it that also have soaphorns. ”

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

"Okay! If there's anything that doesn't work, I'll take you there when the snow melts. Cheng Minglian smiled and narrowed his eyes, but he was useful.

Among the siblings, the older of them is always inferior to the two younger, who doesn't have a little complicated emotions in their hearts? If he can help, it's too late for him to be happy.

Solving a matter that existed in his heart, Mingyi had a soft smile between his eyebrows.

"Brother Lobby, Second Cousin, Third Cousin, Fourth Cousin, do you think our soap can be sold?"

"Yes, surely!" Cheng Mingyi's words were full of firmness, "How can no one want such a good soap; How should the price be determined? ”

Mingyi silently calculated the cost of soap, but there was no other cost except lard; The mold can be made at home, and the grass ash is available at home, and if there is no livestock, the plant ash will be useless.

I just wash my clothes on weekdays, and I can't use them up at all.

"Ten cents a piece, let's make a batch and sell it." Mingyi said.

Cheng Mingyi asked puzzledly, "Can't you do some to sell first?" ”

"Yes, yes, but our soap has no technical content, and if someone is interested in research, it is easy to study it; Therefore, this time the soap may only be sold a few times, and the number must be more. ”

Don't underestimate the wisdom of the ancients.

Cheng Minglian said uncertainly.

"Probably not, right? If you don't, we don't know. ”

Cheng Mingzhi said: "According to what Yiyi said, Yiyi is right, we can't think of it, can't people think of it?" ”

Cheng Mingxin nodded, agreeing with his brother's words.

"Then listen to the instrument, go, make the mold; To do more, the mold can not be less, and the problem of lard must be solved. Once the idea was cut in, Cheng Mingyi quickly sorted out the way.

Mingyi nodded, "I'll leave this matter to my father, uncle, and second uncle." ”

"Okay, let's go to make the mold first, Yiyi and Mingli will talk to my father, uncle, and third uncle; Buy the lard early, the lard has to be boiled before it can be used. ”

The four cousins walked away shoulder to shoulder, and Cheng Mingli and Mingyi took the remaining four pieces to find their father.

When he found someone, his father and grandfather were talking together, and they didn't see the eldest and second uncles.

"Daddy, grandfather."

The two walked forward and shouted.

Cheng Dazhu nodded and smiled kindly, "Are you here, are you cold?" Look at your little faces that are red from the cold. ”

"It's not very cold." Mingyi stepped forward with the soap in her hand, "Grandfather, father, look, this is the soap we made; It is very useful to wash clothes and wash hands. ”

"This" Cheng Dazhu reached out and touched it uncertainly, a little slippery, more smooth, "Have you used it?" ”

Mingyi nodded, "Brother Lobby, they have used it, and the clothes that are not seriously dirty will be cleaned as soon as they are washed; If the dirt is serious, it should be washed for a while, which is much easier to use than the plant ash we use. ”

"That's really good." Dingding stared at the soap, and after a while, he looked up at Mingyi, "This is what you plan to make and sell?" ”

"Well, it's priced at ten cents a piece, this thing is fresh; Let's make more and sell it for four or five thousand yuan at a time. ”

Cheng Mingli added: "My sister said that soap is made, and others will be able to study it soon; Therefore, if you do more at a time to sell, you can make more money. ”

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

"Good, good boys, all good boys; I'll let your father and mother help together, no matter whether you make money or not, you are not afraid, and you can do it boldly. Cheng Dazhu calculated the materials needed for Mingyi, and so far only let the third child buy lard.

That half of the lard has not been used up for two days.

A piece of lard is about 100 yuan, and if it is made and sold, the profit is very considerable.

"Is your lard enough?" Cheng Dazhu asked again.

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

"Is it enough for your dad to buy three more pairs?"

"I don't know, I can only do it." can't give a clear answer, too clear, she will be exposed more; Today's intelligence is just right, and there are some things that need to be supported by the elders.

Cheng Dazhu slapped his forehead and suddenly realized, "I took it for granted, then buy three pairs of lard first; Third, you call your eldest brother and second brother to go to Fucheng with you to find lard. ”

The second watch is in place, sleep well~~ Good night, Bao'er
