Chapter 465 Missing?

Fudan University, Chemistry Experiment Building.

It was already eight or nine in the evening. There were only a few people left in the building except for the hard-working researchers waiting for the results. Most of the lights in the corridor were turned off.

In a laboratory, Zhou Rui was operating a vapor deposition instrument to vaporize the initial compounds inside.

He borrowed this laboratory from the school specifically for his graduation thesis.

Chemistry papers cannot be separated from experiments. No matter how high the level is, it is not advisable to write a paper without words. Too much content needs to be filled with experimental data.

He was not in the mood to buy a lot of special instruments, so he borrowed the school's laboratory.

But he only came at night, there were fewer people and less things to do, so he could do it quietly.

"Research on the vapor deposition method of perovskite crystals and large-scale engineering preparation methods"

This is the topic he decided on, and he thinks it is more suitable for him.

One is to span the three fields of chemistry, materials, and engineering, and the most important thing is that it can be close to his strongest subject "engineering", which is easier to produce results.

Second, perovskite solar energy is a relatively hot field, and there are some fragments of past life that can be used as reference.

The third is the most interesting, and there are many cross-fields with the earliest metal magnetron sputtering coating.

However, he does not plan to spend too much time, and plans to finish it within a week, which is already fast for a graduation thesis.

After that, let Wu Huamin change the format.

By the way, the nominal supervisor of his graduation thesis this time is also Wu Huamin.

It belongs to self-production and self-sales.

"Zhou Rui, the materials are used up, why don't we end it first? There is a light show today"

Han Ziyin stood by her side in a white coat.

The research assistant returned again, and the two seemed to have returned to the earliest "metal sputtering laboratory", cooperating with each other and having a tacit understanding.

But the relationship has long been different.

Zhou Rui stretched lazily after hearing this, and said: "Then pack up and go, where are you going tonight?"

Han Ziyin paused: "I'll go back to the dormitory"

Why do you feel insecure, girl?

Zhou Rui put his arm around Han Ziyin's waist and said with a smile: "Come back with me, my cat can do backflips"

Han Ziyin: "You don't have a cat"

"Meow meow"

Just as he was about to spend some time with Han Ziyin in the laboratory, Zhou Rui's phone vibrated slightly. He took it out and opened it. The contact was saved, but the name was unfamiliar

"Zhang Cheng"

Who is this?

Zhou Rui answered the phone, and a middle-aged male voice came from it. I don't know if it was because he acquired the [Voice Skill] that he was particularly sensitive to voice and voice line, and finally remembered who the caller was.

Zhang Xin's father

About half an hour later, Zhou Rui met this man who he hadn't seen for a long time at the KFC at the gate of Fudan University.

The last time they met was when they had just graduated from high school. At that time, Zhang Cheng, as a parent, brought Zhang Xin and others to Shanghai to study.

As a civil servant who has worked for half his life and is still a grassroots civil servant, Zhang Cheng has always had a cautious aura, but this time, Zhou Rui felt that this man was exhausted and frightened.

Seeing Zhou Rui, Zhang Cheng tried to put on a smile.

"Mr. Zhou, I'm sorry to bother you."

Zhou Rui quickly shook his hand: "Uncle Zhang, don't say that, you are an elder, just call me Xiao Zhou."

If we say where Zhou Rui is most famous, Fuda can only be ranked second, and Qinghe County is the first.

Any news related to Zhou Rui will be quickly spread in the county, even if Zhou Rui's family no longer lives there.

In the past two years, Zhang Cheng has been watching Zhou Rui's rise from afar. Now Zhou Rui is definitely a big boss in his eyes, no longer as casual as before.

After Zhou Rui sat down, he said in a deep voice: "Uncle Zhang, did you say Zhang Xin is missing?"

Zhang Cheng held a cup of KFC coffee in his hand and kept rubbing it, as if he wanted to get some heat.

After a while, he said: "I don't know if it counts as missing. The police said that he is an adult, not counted"

Zhou Rui frowned slightly: "Tell me what happened in detail."

Zhang Cheng was silent for a while and told the story.

Zhang Cheng is a man who lives a decent life. After sending Zhang Xin to Shanghai to study at university, he felt relieved.

He always thought that his son was studying hard in Shanghai, and that finding a good job in the future was his biggest wish. As for whether he could stay in Shanghai, he didn't dare to think too much.

He often called his son on weekdays to ask about his well-being, whether Zhang Xin had enough living expenses, and how his studies were going.

But about three days ago, Zhang Xin's phone was always unreachable, either no one answered, or occasionally it was disconnected.

Zhang Cheng suddenly lost contact with Zhang Xin completely.

Zhang Cheng was a little worried, so he contacted the school to inquire about Zhang Xin's situation.

As a result, the school told him that Zhang Xin had been on leave for several months.

And it seemed that the parent's signature on the leave application was forged.

This was completely different from the information Zhang Cheng received on weekdays. Two days ago, Zhang Xin said that he was preparing for the final exam at school!

After thinking about it, he felt that the matter was serious, so he took a leave and came to Shanghai.

He took a hard seat train all night and just arrived in Shanghai in the morning. He immediately went to Zhang Xin's university. He ran around the campus all day but gained little. His classmates said they hadn't seen Zhang Xin for a long time.

They were even surprised that Zhang's father was so poor.

Zhang Cheng learned some confusing information, such as Zhang Xin was very rich, he was very popular when he was in school, and it was rumored that he knew some gangsters.

Putting these things together, Zhang Cheng deduced that Zhang Xin must have "learned bad things".

But now it doesn't matter whether he has learned bad things or not, what matters is where he has gone?

If he wants to beat him up and drag him back to school, he must find him first!

This was the first time he encountered such a thing, and he subconsciously went to the police station around the school to seek help.

But Zhang Xin is an adult, not a child. If he has not been contacted for just three days, it will not attract the attention of the police unless Zhang Cheng can prove that Zhang Xin's personal safety is threatened.

In the words of the police, Zhang Cheng's situation is not uncommon. Every year they receive a large number of similar cases. He can't contact his parents for a week when he stays in an Internet cafe, and he may not contact his parents for a few days when he goes out with his boyfriend.

It is impossible to file a case for investigation. We can only help him keep an eye on it and ask the police to look at the young people staying in Internet cafes during patrols, and then let Zhang Cheng go back and wait for news.

This is also understandable. If every parent who can't find their child (adult) has to file a case for investigation, how much police force will it take?

Not answering parents' calls, or learning bad things, or dropping out of school, are not situations where the police need to intervene.

Zhang Cheng was unfamiliar with Shanghai, and he wanted to get a result after coming here, at least to confirm that Zhang Xin was safe.

He was restless until the evening, and finally held a glimmer of hope and contacted Zhou Rui nervously.

He thought that Zhou Rui was also in Shanghai after all, and was Zhang Xin's friend, so maybe he knew something.

Zhou Rui frowned slightly after listening to Zhang Cheng's statement.

He had previously guessed how Zhang Xin explained his special situation to his family.

He even thought that although Zhang Xin was involved in the gray area, with such a high income, maybe his family acquiesced to this situation.

But he didn't expect Zhang Cheng to be completely unaware?

He didn't think Zhang Xin would have any personal safety problems, maybe he was wild? Maybe he lost his phone?

Maybe this kid was even so fierce that he was caught for drunk driving?

It seems that this is really possible! Last time, this kid didn't listen to advice, and he even crushed his car keys.

Zhou Rui pondered for a moment and was about to persuade him.

Zhang Cheng's phone vibrated.

He had been using his phone for the past few days and even bought a power bank. He was afraid of missing Zhang Xin's message, so he immediately looked over.

But he found it was a remittance message.

The sender was a stranger, and the note read: "Dad, keep this money."

The amount was 500,000.
