Chen Ye glanced at the several large pieces of tofu in the basin, which were still trembling with steam. The aroma of beans rushed into his nose, and Chen Ye wanted to take a bite of them directly.

He swallowed and asked, "Is this newly made?"

"Not so good. We were the first in line, and we were afraid we wouldn't be able to exchange it if we were late. We even brought all the soybeans from home."

Grandpa Zhang’s tofu is not exchanged for money, but directly for soybeans, otherwise they don’t have so many soybeans to make tofu.

"Have you used up all the soybeans? What are we going to do during the Chinese New Year? No more tofu?"

"We'll talk about it later. It smells really good. Do you think we can still eat such delicious food when Shuanzhu grows up and joins the army?"

"Then you won't study hard?"

Cen Zixiang sighed, "I did study hard, but this thing is not something you can master simply by studying hard. Don't just blame me, why don't you work harder? At least your starting point is higher than mine."

Chen Ye…If she could improve, her cooking skills would have improved long ago.

"I can't do it. I don't have the talent." Chen Ye was very honest and said directly that he couldn't do it.

The brother and sister sighed to each other and said, well, every extra meal counts. It’s almost the thirteenth day of the lunar year, so shouldn’t we grow up quickly?

In about three years, they might leave here, and it would be unlikely for them to continue to eat Shuanzhu's cooking, unless they take Shuanzhu with them. But Shuanzhu can't help but go to school and become a chef with them.

"By the way, fourth brother, Grandma Tian said that the ratio of our recipe can be adjusted. The effect will be better after the adjustment. Do you want to go back with me to experiment?" Later, if she wanted to find someone to sell the recipe, her fourth brother would have to come. She was determined that it would not work.

"What's changed?" The formula for this laundry detergent was found on the Internet in later generations. It was the most common laundry detergent formula. If he didn't have a good brain, he wouldn't be able to remember it.

The two of them heated up the soy milk on the small stove in the back. Chen Ye mumbled something about the recipe, and Cen Zixiang's eyes lit up when he heard it: "Right, right, that's the right change."

Although he was said to have a good brain, he did not have a photographic memory. Besides, he had only glanced at the formula of the laundry detergent a few times and did not try to remember it. When he first said the formula, he seemed to feel that something was wrong.

But he didn't study chemistry, so he couldn't figure out what was wrong. When it came to tinkering with chemistry, he might not even be as good as his younger sister. It turned out that there was a mistake in the ratio.

"Sister, you have to do this. Your fourth brother and I are not very good at chemistry. You can also make the laundry detergent. I will find a buyer for you next time you come over."

Anyway, the brother and sister had no intention of making money in the black market. If someone really caught them, it might affect their family's work. Their family had worked hard to make a living, and it was not worth taking risks for a little money.

Fortunately, everything is in short supply in this era. The transparent formulas that are everywhere on the Internet in later generations do not appear now. They cannot make money illegally, but they can make money openly.

If people knew about this, they would also praise them. They didn't make money directly from selling their products. They did it to generate income for the factories. With the rewards from the factories, they were also indirectly contributing to the country's construction.

"But Brother Si can only roughly remember what was used in the laundry detergent. As for the specifics, I have no idea. You'll have to figure it out on your own."

Look how well he does as a brother. He finds something to entertain his younger sister. Otherwise, his younger sister would be like a carpenter, thinking about renovating the house every day. How could she live in so many houses?

Chen Ye nodded. This was already a great advantage. If she were asked to start from scratch, she really couldn't do it. As for whether they would feel guilty about stealing the limelight from future research on this person, they would have to bear the consequences.

That would definitely be a good thing, this is completely different from the original world. Besides, her sense of morality is not that high. On the contrary, she thinks that if she seizes the opportunity to produce these things, she may even generate income for the country.

"Okay, then I'll go back and try it slowly. I'll be able to make it eventually."

"Oh, and there's dishwashing liquid. Do you know the formula, Fourth Brother?"

"I do know, but I don't know the exact ratio. I can only remember the rough idea. You know I didn't study this at all."

Chen Ye nodded in understanding: "It's pretty good to know the general idea. It's much better than me."

The brother and sister, one provided ideas and the other did experiments. They each split the money earned from the work in half. They agreed that in the future, each of them would sell a courtyard house with an entrance, and they would live next door to each other and become neighbors.

They both want a big house, but they have to be able to afford it.

Seeing that more and more people were coming over, the two of them stopped talking about this topic. Shuanzhu was busy and didn't notice what the two of them were whispering to each other. Shuanzhu was a carefree child.

But those old men are very smart, so they must be more careful when they speak, because any sign will be noticed.

"By the way, after dinner, don't leave yet. Help me get rid of the meat. We can't just leave it like this in this weather."

Cen Zixiang was a little worried when he thought about the huge pile of meat. Too much meat was not a good thing. It would mean more work. He muttered quietly, "It would be great if there was a refrigerator."

Chen Ye glanced at Cen Zixiang and thought it was a beautiful idea. She had actually looked for one during the summer, but it was a pity that no one in the provincial capital sold refrigerators, let alone bought one. Even if there were some for sale, it would be very difficult to buy one.

But we can study and see if we can make one. All we need is a freezer. But it should not be easy. After all, she has never seen such a thing before. How can she come up with the idea of ​​making it?

Unlike washing machines, at least there are stores selling them, and you can have a reason to buy one.

Apparently, Cen Zixiang had thought of this after mumbling, "It would be great if grandpa and grandma were still in the capital. That way, we could go back for the New Year, and I could take you to the Overseas Chinese Store to look at the refrigerators. Wouldn't that give us an excuse?"

When Chen Ye saw his grandmother coming in, he kicked Cen Zixiang and said, "You should be more careful with your words. You are speaking more and more casually."

"Grandma, why did you come in? It's so choking in here. Please come in and sit down. We'll be fine soon."

The old lady touched the tied head and said, "This kid, I wanted to come over to help but he wouldn't let me. He must be exhausted from cooking for so many people by himself."

His eyes narrowed into slits in an instant: "I'm used to it. My grandpa and his family would get together for dinner from time to time, and I cooked it all by myself."

The main reason was that Shuanzhu disliked the old men's slowness and thought he could not work as fast as he did. Sometimes he had to clean up the mess made by the old men, so he would rather stay in the kitchen alone.
