A powerful country in scientific research

She walked over quickly and said with a smile, "He Cheng, Sister Zhang Xue and Xiao Yun are going back with me today, so you don't have to see me off, just go back." She lowered her head and didn't dare to look at He Cheng, for fear that he would see the guilt in her eyes.

He Cheng asked in surprise: "What are Sister Zhang Xue and the others doing there?"

Su Ran: "I have a heated kang, they can go over and try it out and sleep with me tonight."

He Cheng: ...I lost two opportunities to spend time with my girlfriend at once.

He said aggrievedly: "Well, then I can't pick you up tomorrow." He sighed and continued, "Others value women over friends, but you value friends over women."

Su Ran felt even more guilty. She cleared her throat and forced a change of subject: "You can go and have a look tomorrow night. That kang is really nice. You can get one at the educated youth camp."

He Cheng chuckled, "Okay, I'll go over and take a look tomorrow."

Su Ran felt relieved when she saw that he no longer mentioned the issue of "putting women before friendship". Although she loved to flirt, she was also easily timid.

Su Ran: "Well, then you should go back quickly and don't delay your meal."

He Cheng: "Well, then I'll leave?"

Su Ran nodded and watched him get into the car and leave. Then Su Ran walked to the door and waited silently for Zhang Xue and the others to come out.

After everyone came out, Su Ran locked the door, and then the three of them walked towards the Jiangshui Brigade while talking. It was time to get off work, and the three young and beautiful girls talking and laughing were very eye-catching, causing passers-by to stretch their heads to look.

Jiang family.

Since work ended in the morning, people kept coming to the Jiang family. When the first person came, Grandma Jiang was still puzzled. After she told her purpose, Grandma Jiang realized that it was Fusheng who mentioned the kang. Grandma Jiang hurriedly took them to Ranran's room and wing room respectively.

Before Fusheng left yesterday, he discussed with them whether to let the team members come to their house to view the finished product and see the effect. Jiang Fusheng felt embarrassed when he said this. After all, there were many people in the team. If they all came, it would disturb Grandma Jiang and Grandpa Jiang too much.

When Grandma Jiang, Grandpa Jiang, and Su Ran heard what he said, they agreed without hesitation. After all, whether it was a brick bed or a soil bed, it would cost a lot. The team members only earned so many work points throughout the year, and there was only so much food. If they were asked to make something they had never seen before, they might not be willing to do it. Although they knew it was good, they might not believe it. After seeing the real thing and the effect, the team members were willing to build one even if they knew it was expensive.

In order to let everyone see the effect, Grandpa Jiang lit up both kangs early in the morning. The fire stayed on all day and both rooms were very warm.

Grandma Jiang and Grandpa Jiang stayed at home the whole time and did not go out. They entertained many people today, but they did not complain. After all, these people did not come in vain. After seeing the kang, they kept praising Su Ran, and the two old people felt very happy.

The couple had just seen off a group of people and were sitting on the sofa to rest.

Grandma Jiang suddenly realized that it was already past six o'clock. She slapped her thigh and said, "It's already past six o'clock, Ranran is about to come back, and we haven't cooked yet!" After that, she stood up quickly and wanted to go to the kitchen.

Grandpa Jiang grabbed her and comforted her, "There's still time! You've been tired all day, take a break first, I'll help you later, the two of us can finish it faster."

The two of them rested for a while and recovered some strength. Just as they were about to go to the kitchen to cook dinner, they heard faint laughter coming from the door. One of the voices sounded quite familiar, a lot like Su Ran.

They were right in hearing it. The next second, Su Ran came over with two girls.

Su Ran saw that her grandparents were sitting on the sofa, so she greeted them and then introduced the two people next to her, "Grandma and grandpa, these are my colleagues from the experimental field, Zhang Xue and Li Yun. They came here today to take a look at the kang and sleep with me tonight. Sister Zhang Xue, Xiao Yun, these are my grandparents."

Zhang Xue: "Grandma, Grandpa, hello."

Li Yun: "Grandma, Grandpa, sorry to bother you."

Grandma Jiang smiled and said, "Comrade Zhang, Comrade Li, I've heard about you from Ranran a long time ago. Come sit down and have some water."

"Eh."

"okay."

Grandpa Jiang said with a smile: "Of course, you can take the two little comrades to have a look. Your grandma and I will go to cook."

Grandma Jiang: "Yes, yes, yes, go and have a look. The kangs in both rooms are lit. The rooms are very warm."

Su Ran was surprised, "You lit the fire so early?"

Grandpa Jiang: "Didn't your uncle say yesterday that someone was coming to visit today, so your grandma and I got angry this morning."

Su Ran nodded. "Are there many people here today? How do you like it?"

Grandpa Jiang was all smiles. "A lot of people came. It feels like half of the team came. Everyone who came praised it. They all said it was good. I guess a lot of people want to have their kangs repaired."

Su Ran curled her lips, "That's good, then Grandpa, I will take Sister Zhang Xue and Xiao Yun to take a look inside the house."

Grandpa Jiang: "Go ahead, go ahead. Your grandma and I are going to cook."

Su Ran nodded, and then took Zhang Xue and Li Yun to the house where she lived.

Zhang Xue and Li Yun followed Su Ran expectantly. After entering the house, they were immediately shocked by the temperature in the room.

Not long after coming in, Li Yun felt herself sweating. It was too hot and she wanted to take off her clothes.

Zhang Xue had the same idea. This house was warmer than the buildings in the city...

Su Ran smiled and said to the two people in front of him, "This is a brick kang, which is a fire kang made of bricks. Should we go to the wing room to take a look at the kang now, or should we take a rest first and then take a look after that?"

Zhang Xue and Li Yun looked at each other and said in unison, "Let's go now."

They are really curious~

Su Ran didn't waste any time and took the two of them to the side room.

Zhang Xue felt the same temperature as the room just now, and said in surprise: "Of course, these brick and earth kangs seem to be very useful."

Su Ran smiled and nodded, "Yes, it's just that the cost is a little lower, the sturdiness is a little lower, everything else is about the same."

Zhang Xue: "How much do these two cost?"

Su Ran: "I haven't really calculated this, but I estimate that a brick kang costs about 20 yuan, and an earthen kang costs three yuan? About the same. An earthen kang also uses some cement, wood boards, etc., plus the workers' wages, so it's about this amount. In fact, you don't need cement and wood boards, and the price will be even lower."

Li Yun was a little shocked. The brick kang was so expensive!

Zhang Xue, who came from a big city, was fine. Her monthly salary was only over 50 yuan, so 20 yuan for a kang was acceptable. She was somewhat tempted.

The family she was relying on was of average condition, with only a grandmother and her granddaughter. Apart from the work points her grandmother earned, the family had no other income, so they did not live well.

Both of them were very nice to her, so she really wanted to do something for them, and this kang was a great choice!
