Chapter 107: Midterm Exam

Zhao Zhaodi hesitated.

Zhou Miao also said: “Yes, Zhaodi, don’t catch a cold just to save money. Besides, a cotton coat can be worn for several years.

If you don’t buy it this year, you will have to buy it next year. You can’t wear these clothes forever, right?”

Li Huanhuan also nodded: “I still have some money in my hand. I will lend it to you. You can pay me back when you have money in the future.”

Zhao Zhaodi’s defense line dropped a little after hearing this, but she was still a little hesitant: “I can still make it this month. I will have money next month.”

Her family conditions are not good. Her husband came to Sijiu City to work and take care of the children.

Although he doesn’t need to pay for her education, the pressure of life is still very high.

Sijiu City is not like her hometown. Everything is much more expensive, so they don’t have any money saved.

Dabao has long been old enough to go to kindergarten. She and her husband only gathered the money for kindergarten last month.

Shen Sangyu probably knew what Zhao Zhaodi was thinking and whispered: “What are you going to do next month? Go now, take the child with you, and go to the supply and marketing cooperative to look at clothes.”

Zhao Zhaodi was stunned.

Shen Sangyu said: “Don’t let the child get cold.”

This sentence made Zhao Zhaodi’s eyes red.

This time she did not refuse again. After saying a rough date for repayment, she went outside with everyone to pick up Dabao.

Shen Sangyu had met Zhao Zhaodi’s husband. He was a very honest man. He was not very tall in the north. He lived with his son in a shed.

The shed was very simple. It was built with blue and red curtains and some wood. The place was not big, but it was full of people. The environment was not very good.

But the little guy adapted very well.

When he saw Zhao Zhaodi coming, he ran over.

The shed was full of men. Shen Sangyu and the others did not go in from the outside.

Obviously, Zhao Zhaodi was not here for the first time. On the way, she brought her husband a box lunch brought from school.

The man smiled honestly. Hearing that he was buying clothes for his son, he quickly took out the wrinkled money from his pocket and said, “Don’t just buy for Dabao, buy two sets for yourself. Sijiu City is not like our hometown. Don’t catch a cold.”

The man spoke in dialect, and Shen Sangyu, who was outside the shed, couldn’t hear it clearly.

Shen Sangyu was sure that Zhao Zhaodi’s husband was a good man.

Even though the family was living a hard life, when he heard that Zhao Zhaodi had the opportunity to study, he still chose to leave his hometown and bring his wife and son to work in Sijiu City, which he was not familiar with.

After a while, Zhao Zhaodi came out with red eyes.

Shen Sangyu took advantage of the supply and marketing cooperative to buy clothes while it was still open.

Compared with buying ready-made clothes, it is actually cheaper to ask a tailor to make them, but now the weather is cold, and it will take at least half a month to make a piece of clothing.

So in the end, Shen Sangyu bought a set of clothes for each of them.

When Dabao came, he only wore a thin sweater and coat, and when he left, he had two new sets of clothes and cotton pants.

Mom said she would give money to her sister, but her sister said that it was new clothes for him for the New Year.

Dabao thought that it would be a long, long time before the New Year.

But this did not prevent him from being happy.

Because when he left, his mother also bought a black cotton coat and warm pants for his father.

This winter did not seem to be as cold as usual.

In the end, Shen Sangyu only took the money for Zhao Zhaodi’s clothes and asked her to pay some back every month.

Zhao Zhaodi knew that Shen Sangyu was helping her sincerely, and she kept saying thank you.

She could not do anything for Shen Sangyu on weekdays. Knowing that Shen Sangyu had to do experiments for the midterm exam and had no time to eat, she simply went to deliver lunch every day at noon.

There were no midterm exams in the first year of college, and the other teachers did not assign tasks, but Qin Duanshan gave the topic.

It was not difficult for Shen Sangyu, but it was a headache for students who had just started to formally learn physics.

Qin Duanshan gave four topics during class that day. Each pair of people worked on one topic. According to the lottery method, Shen Sangyu drew the topic of underwater power research. Shen Sangyu naturally asked He Huai to go with her.

Shen Sangyu could probably guess some of the topics given by Qin Duanshan. In the next few decades, China will basically focus on these topics.

Among them, underwater research is the slowest and the least.

Not only China, but also other countries.

There is too little exploration of underwater in any field. Before she crossed over, human exploration of the sea was less than 5%, but the ocean covers 71% of the earth’s surface, which means that for humans, 95% of the seabed is unknown. Resources will run out one day, so after exploring the land, they will naturally turn their attention to the sea.

However, there are still many problems that have not been solved.

How can humans go to the sea?

Ancient humans built ships, and now people build submarines, but even so, the degree of exploration of the ocean is only 5%.

Shen Sangyu calculated the time. Qin Duanshan was indeed planning to build a submarine at this time. So this project was probably also to select useful talents?

Shen Sangyu narrowed her eyes, glanced at He Huai who didn’t know the situation yet, and suddenly asked: “Are you confident?”

He Huai didn’t even think about it: “Of course I am!”

Shen Sangyu smiled: “If you are confident, then let’s do it!”

He Huai saw Shen Sangyu, seemingly full of energy, taking him to the library and finding several thick books.

He Huai swallowed his saliva, a bad feeling growing in his heart: “What are you going to do with so many books?”

Shen Sangyu handed all seven or eight books to He Huai and said seriously: “What else can I do? Teacher Qin gave us three weeks to do the experiment, so within a week, you should roughly read all these books. I will tell you the key parts, and then we will make the model.”

Shen Sangyu then quickly began to think about the production cost.

Generally speaking, schools subsidize students to do experiments. Otherwise, experiments are so expensive. Who can afford to do experiments with nothing?

He Huai, standing aside, was still in shock.

Seeing the books in his hand, his body trembled.

“So… Can I drop out of school and take the college entrance examination again next year?”

Shen Sangyu looked at him with a murderous look, and He Huai instantly shut up.

He Huai was helpless: “Then… then I’ll try my best.”

There were exactly seven books, so it was not impossible to read one a day.

On the same day, Shen Sangyu called the military district to tell Wen Qingchuan that she could not go home because she had to do an experiment.

Wen Qingchuan was slightly disappointed and asked: “Then take care of your health, don’t save money at school, and order a small stir-fry every day.”

After a pause, Wen Qingchuan said again: “Don’t eat dry mixed rice noodles every day, it’s easy to be malnourished.”

Shen Sangyu: “…”

After thinking silently for a while, it seems that she had dry mixed rice noodles for lunch today.

Shen Sangyu’s face flushed, and she quickly said: “I’ll go to eat stir-fry in the evening!”

Wen Qingchuan laughed: “Then you had dry mixed rice noodles for lunch again?”

Shen Sangyu: !!!

The little girl snorted coldly and hung up the phone.

On the other side, in the military district compound.

The sound of Shen Sangyu hanging up the phone was not small, and Shen Xu, who was eavesdropping on the side, heard it clearly.

Seeing his boss standing there in a daze, he couldn’t help but laugh: “Boss, you made your sister-in-law angry again?”

Wen Qingchuan looked over and said, “What do you mean by again? When has Sang Yu ever been angry with me?”

Shen Xu immediately felt a handful of dog food being stuffed into his mouth unexpectedly.

“You’re the only one who has a wife, right?” Shen Xu muttered, and then asked in a sly way, “Is your sister-in-law not coming back this weekend?”

As he spoke, Shen Xu glanced at the bag of rice noodles in Wen Qingchuan’s hand.

“Yeah.” Wen Qingchuan had no emotion on his face, and glanced at Shen Xu: “Call the brothers tonight, I will treat you to dry mixed rice noodles.”

Shen Xu: “… No, we have been eating dry mixed rice noodles for a week!”

Shen Sangyu hung up the phone and returned to the dormitory to calculate the cost of making her simple model.

The underwater power model she was going to make was the most basic key to a submarine.

Now Shen Sangyu didn’t know how far China’s submarine technology had developed, but before she crossed over, China’s submarines had passed a depth of 3,500 meters, and she was studying a depth of 10,000 meters underwater at the time, but she crossed over when the experimental research was halfway through.

Now China’s technical conditions are not yet able to explore a depth of 10,000 meters, but 3,500 meters is still possible.

Shen Sangyu lay on the table and wrote down the equations and the money needed for the materials, planning to go to Qin Duanshan for reimbursement tomorrow.

Shen Sangyu stayed up until two in the morning, and finally went to bed because she couldn’t hold it anymore.

As a result, Shen Sangyu successfully stayed in bed the next day.

There are only four of them in the dormitory now. Today is the weekend and there are no classes. Zhao Zhaodi goes to accompany Dabao every weekend, while Zhou Miao and Li Huanhuan go to the library to study.

Knowing that Shen Sangyu has an experiment to do, Zhou Miao woke her up in the morning when she saw that Shen Sangyu had not woken up yet.

Shen Sangyu was not in a bad mood when she got up, but it did not mean that she did not stay in bed.

When Zhou Miao was talking to him, Shen Sangyu was still a little confused. She stretched out a finger and said, “Sleep for another ten minutes, just ten minutes…”

After saying that, she put the quilt on her head and fell asleep in less than a second.

Seeing this, Zhou Miao could not help but complain to Li Miaomiao, “Is Sangyu hibernating?”

I have never seen her unable to wake up in the summer?

Li Miaomiao nodded seriously, “I think so.”

After that, the two could only resign themselves to calling Shen Sangyu to get up.

In the end, Shen Sangyu was no longer sleepy and got up from the bed in a daze.

It took a while for Shen Sangyu to react. As if she had thought of something, she jumped off the bed and said, “Fuck!”

Zhou Miao watched Shen Sangyu pack herself up in less than five minutes, and then hurried downstairs without even saying hello. She

was so fast that Zhou Miao felt a gust of wind running past her.
