Turning over and turning to the other side, he was optimistic about that person, but now, he felt a little disappointed and felt that his vision was a bit bad, and he could always bring those bad thoughts into the door.

After breakfast the next day, Professor Song and Professor Jian went to the school's laboratory, while Xu Mumu and Yin Yang stayed at home.

Yin Yang brought Xu Mumu to the small yard next door, which was directly rebuilt. The small yard was very spacious, with a laboratory built inside, and there were various materials and experimental equipment.

"Are you satisfied? What else is missing? I'll let Yun Hong get it." Yin Yang said gently.

"It's enough for the time being. Let me tell you when I'm missing something." Xu Mumu was simply too satisfied. Yin Yang was so considerate. She needed a quiet place. She had seen these experimental equipment in school. Although it was not as sophisticated as those in later generations, it was enough now.

"Okay." Yin Yang nodded with a smile. These materials were all rough lists he had listed himself. Then Zhou Yunhong bought them. Now that Xu Mumu can use these things, he was naturally happy.

Xu Mumu spent the whole morning in the laboratory here. She also clearly stated that the air conditioner structure was invented as early as the early 20th century. It was okay for her to make it happen now, but it has not become popular in China yet, and no one can afford it now.

When you get it out, use it yourself first. When you can do business, then use this craft to Yin Yang to sell it for money. If Yin Yang doesn't want it, sell it to Huo Qingze. He must have wanted it.

Seeing Xu Mumu staying next door to work on her air conditioner every day, even Professor Song was very interested. Professor Song mentioned that the two of them worked together and the speed of getting these things was much faster.

It’s just that the school day has begun, and the two of them have not yet done it.

Seeing Xu Mumu staying in the laboratory every day, Yin Yang regretted building the laboratory. It was not enough to have a grandfather who was obsessed with experiments at home, and now he has another one.

If he hadn't had a lot of things to do here, he would have been resentful.

"Mu Mu, I'll help you get the bag." Yin Yang took the bag Xu Mu Mu was carrying, and the two walked towards the school.

There are many freshmen in the school this year, and Xu Mumu has seen some of the people in their class welcome the freshmen.

Xu Mumu didn't like to do these things, so he didn't go to join in the fun.

When she arrived in the classroom, Xu Mumu found a quiet seat and sat down. Su Yue'e wanted Xu Mumu to sit next to her, but Xu Mumu refused. She didn't like Su Yue'e and didn't want to get along with her anymore.

Su Yue'e frowned slightly, but didn't say much. There were still a few girls in the classroom, and it seemed that she had been doing well this summer vacation.

After the teacher came, the boys who followed him brought the books over.

Xu Mumu got the new book and briefly looked through it. She had learned all the contents in the new book. Not only did she learn it in her previous life, but she also checked some of the materials she didn't understand.

I raised my eyebrows slightly and put away the book. I still have many benefits when I understand these things, and I also have more time to use her air conditioner.

The weather is getting hotter and hotter, and it is about to rain, and the weather is getting hotter and hotter, making Xu Mumu's heart stronger when he makes the air conditioner come out.

Speaking of rain, before get out of class was over, it started to rain in the sky. Xu Mumu looked at the sky outside without holding an umbrella.

Just as she was about to run to find Yin Yang in the rain, Yin Yang walked over with an umbrella.

"Where did you get the umbrella?" Xu Mumu asked curiously. When he left, he didn't see Yin Yang bringing the umbrella, and he didn't fold the umbrella for him to put in his bag.

Thinking of folding umbrellas, this is quite simple. Huo Qingze’s stall is in the imperial capital. If you give him the drawings and ask him to make them out, it doesn’t have much technical content. It will be sold fresh from the beginning, and someone will definitely imitate them soon.

"It was Yunhong who sent it during the last class. He thought it would rain, so he sent it first. Unexpectedly, it would rain." Yin Yang said with a smile. Zhou Yunhong looked at the sky very accurately every time. So, the umbrella was delivered for a while, and in less than half an hour, little raindrops floated in the sky.

"It's great to have an umbrella. You don't have to go back in the rain. He is so considerate. You have to raise his salary." Xu Mumu said with a smile, hiding under the umbrella on the other side of Yin Yang, and walking outside the school gate with the envious eyes of other girls in the class.

"By the way, where are Grandpa Song and Grandpa Jian? They should be in the laboratory and office now, right?" Xu Mumu looked at Yin Yang and asked.

"Don't worry, he's giving it to you." Yin Yang curled his lips and put the umbrella at Xu Mumu's side. A little wind broke out and the rain floated.

"That's good." Xu Mumu nodded, relieved. Zhou Yunhong was indeed very thoughtful in his work. The umbrella he gave to Yin Yang was relatively large, so it would be no problem to cover the two of them. This was what he did on purpose. The two of them were almost getting married and they even had umbrellas separately. That was so bad. It would be better for two people to play an umbrella.

When she got home, Yin Yang's clothes were a little wet. Xu Mumu frowned slightly. She didn't notice that she was talking to Yin Yang all the way, but she didn't notice that he moved the umbrella to her.

"What a fool. Don't do this next time." Xu Mumu wiped Yin Yang's face with a dry veil, and then asked him to take a hot shower to avoid getting caught in the rain. His body is more important than anything else. This was summarized by her in the end of the world for more than half a year.

Although Xu Mumu was still quite moved after scolding Yin Yang. Yin Yang was very careful, which made her very useful. Who doesn’t want the man she likes to be considerate enough to him and put himself in the most important position in her heart.

In the kitchen, the aroma of chicken soup slowly spread. It was the rooster that Zhou Yunhong brought from the black market yesterday. When Xu Mumu and the others went out in the morning, Aunt Liu stewed it. It has been stewed all morning now and the taste is very fragrant.

Aunt Liu took the dried mushrooms brought by Xu Mumu and soaked them in the pot. After a while, she could eat them when Professor Song and the others came back.

"Aunt Liu, the chicken soup you stewed is so fragrant." Xu Mumu took two deep breaths of the smell in the air and said with some emotion. To be honest, I miss Aunt Liu's skills during the time I went back.

"Then you have to eat more later. You have lost a lot of weight during the time you go back." Aunt Liu said with a gentle smile. Her children are also studying. Every time she comes back from school, she will prepare a lot of delicious food for the children.
