A powerful country in scientific research

Soon, Su Ran and Grandma Jiang arrived home.

Grandma Jiang opened the door and Wang Guohong moved the washing machine into the house.

Seeing that he was sweating profusely, Grandma Jiang called Wang Guohong into the house for some tea.

"Comrade Wang, you must be exhausted. Come into the house and have a rest and some tea."

Wang Guohong waved her hand, "Aunt, I won't drink. I'm not thirsty. There's water in the car. We still have a long drive on the road. I have to go, otherwise it will be difficult to travel on the road after dark."

Seeing this, Grandma Jiang had to give up and secretly sighed that this young man was too hardworking. Wang Guohong waved her hand, "Aunt, I won't drink anymore. I'm not thirsty. There is water in the car. We still have a long drive on the road. I have to go, otherwise it will be difficult to travel on the road after dark."

Seeing this, Grandma Jiang had to give up.

Wang Guohong said a few words to Su Ran and then drove away.

After Su Ran and Grandma Jiang sent him away, they returned to the house.

Su Ran opened the wrapping paper and carefully inspected the machine. The materials and appearance were both well made and she was very satisfied.

Grandma Jiang looked at the washing machine with curiosity, and Su Ran began to introduce her how to use the washing machine and the precautions. Although Grandma Jiang was old, she was still very smart and understood it quickly.

Su Ran smiled and said, "Grandma, do we have any clothes to wash? Let's try this machine to see if it works."

Grandma Jiang nodded excitedly, "Yes! I'll get it."

After a while, Grandma Jiang came out with some dirty clothes, all of which were taken off yesterday. Because of the busy farming season these two days, she had no time to wash clothes, so Grandma Jiang put them all in the basin and waited to wash them together after she was done.

Su Ran plugged in the washing machine and connected the water pipe. Then he put the clothes in, cut a small piece of laundry soap, and pressed the pull switch.

After a "beep" sound, the sound of flowing water was heard and the washing machine began to add water.

Su Ran and Grandma Jiang were watching attentively from the side. Su Ran was checking the functions of the machine to see if it could operate normally, while Grandma Jiang was very curious. Her curiosity about unknown things made her watch very seriously.

Forty minutes later, the washing machine stopped running, and the clothes in the drum became very clean after being washed and dehydrated.

Grandma Jiang took out the wet clothes but without any water on them, her face full of shock, "The water is gone, so they will be dry once they are hung out to dry."

Su Ran smiled and said, "Yes, it's very easy to do."

Grandma Jiang was so excited, "It will be easy to wash winter cotton-padded jackets in the future."

Su Ran nodded, "Yes, with it, grandma, you don't have to wash clothes with cold water by yourself, hehehe, aren't you happy?"

Grandma Jiang knew that this was something her granddaughter had researched for her. She looked at her granddaughter with a look of emotion, "Of course I'm happy. My granddaughter is so capable and sensible, how can I not be happy?"

Su Ran: "Grandma, I'll go back to the fields first. Grandpa can't handle it all by himself." Seeing that Grandma Jiang wanted to talk, she quickly continued: "Grandma, don't go. Wash the quilt covers at home. It's a good opportunity to try this washing machine."

Grandma Jiang was a little moved.

Su Ran: "Grandma, the weather is getting colder. You should take out the thick clothes and wash them. They have been in the closet for so long that they are very damp. I don't want to wear them without washing them. You don't want to see me catch a cold because I have nothing to wear, do you?" She pouted, looking aggrieved.

Grandma Jiang had no choice but to agree.

Su Ran was afraid that Grandma Jiang would go back on her word, so she ran out of the house.

Grandma Jiang laughed out loud at her funny look, and felt warm in her heart.

Su Ran went to the field, explained something to her grandfather, and then continued to pick corn.

......

Busy times always pass quickly, and two days have passed in the blink of an eye.

The busy farming season was over and Su Ran's life returned to normal.

In the morning, after having breakfast, I went out to work.

Soon, we arrived at the experimental field.

Su Ran hasn't been here for several days. I don't know if it's her illusion, but she always feels that the pigs have grown a lot and the corn is almost ripe.

These days, Su Ran helped his grandparents with the autumn harvest, and Li Yun helped the family with the autumn harvest. All the work in the experimental field was handed over to Zhang Xue, and Su Ran felt very embarrassed.

Su Ran came early today on purpose, wanting to do more work, but Zhang Xue, who was so hardworking, came even earlier.

Su Ran felt that Zhang Xue was the real king of the competition and she could never beat him.

In the experimental field, Zhang Xue was carefully tidying up the weeds in the corn field with her head down, and she would trim them with a sickle from time to time. She looked very serious.

Su Ran approached her and greeted her softly, "Sister Zhang Xue, good morning."

Zhang Xue looked up and saw Su Ran, and responded with a smile: "Good morning, Ranran. Why are you here so early today?"

Su Ran smiled gently, "I haven't been here for a few days. I wanted to do more, so I came here. Sister Zhang Xue, thank you for your hard work these days."

Zhang Xue smiled calmly and said, "Why is it so hard? It's just this kind of work, not as tiring as your autumn harvest."

Su Ran agreed with this point, "Fortunately, the autumn harvest is only a few days away, otherwise I really wouldn't be able to make it."

Zhang Xue covered her mouth and laughed, "Go to the house and rest quickly. I think you need rest more than me."

Su Ran pouted and said, "I'm fine. I can still be saved."

Unable to outwit her, Zhang Xue said helplessly: "Okay, okay, then come with me to pull out some weeds. I don't know why, but there have been a lot of weeds growing recently."

Su Ran: "Okay."

Su Ran looked at the scattered weeds next to the corn stalks and thought that she should arrange some herbicides and come up with a formula that was safe and effective.

She'll have to study it when she has time!

While the two were busy, Li Yun also came.

She thought she had arrived early enough, but she didn't expect Su Ran and Zhang Xue to have already arrived.

Li Yun looked at them guiltily, then joined the weeding team.

The three of them were very fast and they pulled out all the weeds from several acres of land in just one morning.

They returned to the office, breathless, and sat down on the chairs.

Su Ran panted and fanned herself. Although it was autumn, she was still sweating after working for so long. She felt sticky and uncomfortable. If only she could take a hot bath!!

Su Ran's eyes turned, maybe she could make an electric water heater.

Thinking of this, she felt that her schedule was too full. Biodegradable plastics, herbicides, water heaters, each one seemed very urgent.

No, she has to hurry! Su Ran stood up suddenly, said something to Zhang Xue, and went straight to the laboratory. Roll it up!
