A powerful country in scientific research

When He Cheng came out again, he was holding a paper bag in his hand. He put it directly into Su Ran's arms and explained: "I went to the county to deliver oil in the morning. I went to the supply and marketing cooperative and bought a roast chicken. You and your grandparents will have it together in the evening."

Su Ran frowned and said, "It's not good for us to eat too much when you're not here."

He Cheng: "It's okay, our factory is too busy, and we may have to work overtime today. We couldn't have come to your house for dinner anyway."

Su Ran was still unwilling, "Then save it for dinner. Everyone knows that your family is well-off, so it's okay to eat meat occasionally."

He Cheng waved his hand, "I don't eat much meat. I've eaten so many meals at your house, I feel embarrassed. Just let me show my filial piety to my grandparents."

Su Ran: "Okay, then I'll take him back. When you pick me up tomorrow, grandma will probably scold you again."

He Cheng chuckled and said, "It's okay, it's all loving criticism, I'm happy to listen to it."

Su Ran raised the corner of his lips, "Go in quickly, I'm leaving."

He Cheng: "Be careful on the road."

"Good~"

When Su Ran arrived home, Grandma Jiang was tidying up the main room. Seeing her granddaughter coming back, she smiled and said, "Ran Ran, you're back."

Su Ran nodded and said, "Grandma, this is the roast chicken that He Cheng bought when he went to the county town to deliver oil today. You can cut it in the evening." As he said that, he handed over the paper bag in his hand.

Grandma Jiang frowned, "Of course, why is Xiao He spending money recklessly again?"

Su Ran knew that her grandmother would have this reaction, so she smiled and replied, "This is to honor you and my grandfather, how can it be considered a waste of money?"

Hearing this, Grandma Jiang looked at Su Ran with disapproval, "Buying things is just wasting money. Your grandpa and I are not short of money. Don't always spend it on us. Save it for yourselves. You still have to live and raise children in the future."

Su Ran, who is not even 20 years old yet: ...Her grandma really thinks far ahead.

She cleared her throat and changed the subject: "Grandma, where is my grandpa? Isn't he home?"

Grandma Jiang put the roast chicken on the table next to her and said, "Here they are. Your uncle and your cousin Yunhai came to share the kang with you. Since you didn't come back, your grandpa took them to visit the greenhouse."

Su Ran: "Oh, then I'll go take a look."

Grandma Jiang: "Well, go quickly."

In the greenhouse, Jiang Fusheng and his son Jiang Yunhai, under the guidance of Grandpa Jiang, were excitedly looking at the various plants sprouting.

The next second, Jiang Fusheng saw his niece coming over, and he asked excitedly: "Ranran, your greenhouse is well done. What is this?" He pointed to the transparent cover above his head.

Su Ran smiled and said, "Uncle, this is the new material I studied, it's called plastic."

Jiang Fusheng: "This plastic is good. It is light-transmissive and windproof."

Su Ran nodded. "Yes, the biggest problem with growing vegetables in a greenhouse is light. This plastic has good light transmittance and solves the problem perfectly."

Jiang Fusheng's eyes sparkled when he heard this. "Ran Ran, is this plastic expensive? Can we afford it?"

Su Ran: "It's not too expensive, but it's still in the experimental stage, so I can't buy it."

Jiang Fusheng said disappointedly: "Okay, when can I buy it?"

Su Ran: "It will take at least until after the New Year. Planting in a greenhouse is different from growing in the field. A greenhouse is airtight, so there are many things to pay attention to when growing vegetables in it. So we have to wade through the water first and experience all the possible problems. This way, the team members will not have problems building greenhouses in the future, and they will not lose money."

Jiang Fusheng nodded and looked at his niece with emotion. She was worthy of being praised by the No. 1 leader. She was thoughtful.

"So shall we build the earthen kang now?"

Su Ran: "Well, uncle, do you want to help with the foundation?"

Jiang Fusheng shook his head and said, "It's enough for Yunhai to learn. I won't join in." He was afraid that he would learn slowly and delay the progress. He did not forget that the main task today was to build the adobe kang.

Su Ran smiled and nodded, "Okay, then uncle, you mix the cement first, and I will teach Brother Yunhai how to lay the foundation."

"Hey, that's good."

Then Su Ran and his uncle talked about the materials that needed to be prepared and what state they should be mixed in. Jiang Fusheng listened carefully and tried to remember everything in his mind.

After saying that, Su Ran took her cousin Jiang Yunhai into the Jiang family's wing room while her uncle was preparing the materials for the earthen kang.

Su Ran marked a spot by the window and said, "The foundation of the earthen kang is shallower than that of the brick kang. Let's dig a hole first, about 30-50 centimeters will do, and then lay a layer of gravel about 10-15 centimeters thick at the bottom of the hole, and finally pour cement mortar. It's much simpler than a brick kang."

Jiang Yunhai: "Well! I'll dig the hole. Ranran, you can take a rest over there. You must be very tired after a whole day's work."

Su Ran refused: "It's okay, I didn't do anything today, I'm not very tired, I'll dig with you, the two of us will be quick~"

"Okay, then tell me when you're tired."

"Ah."

Half an hour later, the three men finally finished laying the foundation.

Jiang Yunhai looked at the foundation in front of him with satisfaction, and asked Su Ran with a smile: "Ran Ran, are we going to build it up next?"

Su Ran smiled and replied, "Well, that is the bed. Uncle should have prepared the materials for the bed. Just bring it over and we can continue."

Jiang Yunhai: "Don't you want to take a break?" After working all day and doing so much hard work, he felt a little sorry for Su Ran's health.

Su Ran shook his head. "Let's not rest. It's better to finish it as soon as possible so that we can feel at ease."

Jiang Yunhai: "Okay!"

So the brother and sister got busy again.

Su Ran guided Jiang Yunhai as she did it.

"When building a kang, you must pay attention to details such as the kang bed, kang wall, kang head, and flue, especially the flue."

"The flue must be set inside the kang body. When building, you need to pay attention to the position and size of the flue, as well as the connection with the furnace."

"A layer of lime should be applied on the surface of the kang to make it more beautiful and also to prevent moisture, insects and mildew."

Jiang Yunhai listened and tried hard to remember it.

Suddenly Su Ran thought of something and held his forehead with his hand, as if he had forgotten something very important.

Su Ran quickly raised her head and said to Jiang Fusheng who was building the kang, "Uncle, I forgot one thing before. After the kang body of the adobe kang is built, it must be dried first. After drying, the kang will be stronger. So we have to wait for two days." After saying that, she smiled guiltily.

Jiang Fusheng was stunned for a moment, then smiled and said, "Okay, it's okay, then wait for two days."

Su Ran: "Yeah."

Jiang Fusheng: "It's okay, Ranran, you got this earthen kang because we made a last-minute decision, so it's normal that the preparations are not complete. It's our fault. We shouldn't have decided today. We were too anxious. We should have given you time to prepare."

Su Ran waved his hands repeatedly, "Uncle, don't say that. I know you also want the team members to live on the kang as soon as possible and no longer suffer from the cold. It's done well today. Even if we delay it, we have to wait for it to dry. The later it gets, the colder it will be, and the harder it will be to dry."

Jiang Fusheng: "Yes, fortunately the weather is not too cold now."

Su Ran: "Yeah."

The earthen kang at home cannot be tried out for the time being. She will have to talk to Sister Zhang Xue about this when she arrives at the experimental field tomorrow. The plan to try out the two types of kangs will have to be postponed.
