Police Detective

At about three o'clock in the afternoon, the test results of this piece of iron sheet came out.

There was no contraband, but trace amounts of sodium hypochlorite were detected.

This thing is very common and is the main component of 84 disinfectant.

The main component of 84 disinfectant is sodium hypochlorite. Although it is an oxidant, it is not very oxidizing. However, the hypochlorous acid produced by the hydrolysis of sodium hypochlorite under light conditions will decompose to produce trace amounts of hydrochloric acid and oxygen, so it can slightly corrode metals and some adhesives of metals.

According to the test results, the reason why this board fell off has a lot to do with the persistent corrosion of hydrochloric acid. In other words, this place has been disinfected countless times with 84 disinfectant.

This is not the inside of the carriage. Why does it need to be disinfected so thoroughly?

Bai Song even suspected that some bacterial weapons were being researched in this building!

"What's going on? Is this some kind of secret organization that has been flooded by our flood to the Dragon King Temple?" Bai Song asked.

Liu Shuyuan shook his head. He knew quite a lot. If that was the case, it was impossible for him not to know.

"It's hard to say. Many pharmaceutical production units or institutions that develop biological products also have strict control over disinfection." said Sister Zhang, who is in charge of testing.

"Well, thank you very much." Liu Shuyuan continued to chat with her for a few words, took the things and a simple report, and set off home with Bai Song.

Back at work, Bai Song packed up his things. It was almost time to get off work. He did some push-ups in the room and followed Liu Shuyuan to the evening meal.

Today there are no outsiders, they are all within the system, and not only the public security system, but also some people from the government. The oldest is no more than 35 years old. They are all young talents.

In addition to Bai Song, Wang Huadong and Liu Shuyuan, there are five or six other seniors from this school. These seniors before Bai Song were basically all directly assigned to the Municipal Public Security Bureau, and now they are also the mainstays of various agencies and departments.

Because we are all on our own terms, we are not so restricted in what we say. Liu Shuyuan didn't have the wealthy attitude of Zheng Chaopei. He just found a large, quiet room, but the atmosphere seemed more harmonious.

The pleasant dinner ended quickly.

This day was very fruitful. Whether it was at the Criminal Division or at dinner at night, Bai Song gained a lot of popularity. This is also the first time he has some friends outside the Jiuhe branch.

Of course, there is also the Economic Investigation Corps, but as mentioned before, if you don't do well here, you don't have to worry about offending anyone, because you will have less contact in the future. Similarly, the friends I contact here will indeed have few opportunities to collaborate in the future.

But these people I met today are all comrades who will work together for a long time in the next few decades of work. After all, the trenches are closer.

After a glass of wine, Bai Song took a taxi back home.

Ever since that incident in April, Bai Song has never put himself in a less sober state.

After arriving home, Bai Song prepared for tomorrow's classes and felt that he was almost ready before falling asleep.

Tomorrow's class is still very important. Being able to teach a class in front of so many top students, if I can get a little applause instead of boos, it will be an unforgettable experience.

On Saturday morning, Wang Huadong came to pick up Bai Song, and the two went straight to the university.

"You are so energetic today!" Bai Song was quite speechless when he saw Wang Huadong like this. I’ve known him for so long, and this is the first time I’ve seen him in a suit and ties! Even at last night's party, I didn't see him doing things so neatly.

"Aren't we here to listen to your lecture? Wear something more formal to support you." Wang Huadong said with a smile.

"Come on, if you want to chase a girl, just say so. There are so many things to worry about." Bai Song sarcastically said, "You look inexperienced at first glance. How can you wear a suit to chase someone? You look so old-fashioned."

"Ah?" Wang Huadong was really nervous when Bai Song said this, "Really?"

"Look at that look on your face." Bai Song said with a look of disgust: "However, I have inquired for you. This girl is indeed single. Come on."

"Do you still have this connection?" Wang Huadong was very happy after hearing this.

"I called Professor Tang directly to ask. The girl's name is Ding Jianguo. She is 29 years old and is in her second year as a postdoctoral fellow. She and I are from the same hometown in Jade Bird City. Old Tang said that if I know any young talents, I should contact him immediately. "Introduction, this girl cannot be controlled by ordinary people." Bai Song said with a smile: "I will tell Professor Tang directly about you."

Wang Huadong stepped on the brake and stepped on the accelerator. The car suddenly jumped out and almost caught up with him. Bai Song's natural way of switching between "Old Tang" and "Professor Tang" made Wang Huadong confused whether Bai Song was teasing him or telling the truth. He cursed: "Damn it, are you sick? I haven't seen him yet." say what."

"Old Tang said he thought you were good, and he was originally going to introduce a returnee doctor to his students to meet. As soon as I told him, he made no arrangements for the time being." Bai Song interrupted Wang Huadong.

"." Wang Huadong was silent for half a second, "Brother, whatever do you want to eat tonight, I'll treat you."

There are more people today, and the last courseware caused some discussion on the campus network.

Sometimes people are superstitious about authority, even if it is the same reason.

For example, if you are a high school student and you have finished studying electromagnetic radiation, and you go home and tell your grandpa that mobile phones actually have no radiation, nor does high-voltage electricity, he will not believe it. But if the academician boss says it, he will believe it. No matter what he said, every word was correct.

Professor Tang happens to be one of the authorities, so several topics have been hotly searched on some websites and some blogs.

This is indeed a cake that has touched many people, especially some big cakes in the cosmetics industry, but in today's class, no one came to make trouble.

If Lao Tang lectures on quantum chemistry for a day today, wouldn’t it be embarrassing if many of the people below don’t even know how to find fault?

Of course, no one thought that Professor Tang didn’t come to today’s class at all!

It is not feasible to find your own Ph.D. to teach you in a normal class. After all, teaching is also part of the teacher's job. But Lao Tang's position is obviously not restricted, and the school administration will not interfere with open classes like this on weekends.

Moreover, Ding Jianguo is also well-known in school as a beautiful doctoral student. Oh, no, now he has graduated with a doctorate. This is also a legend. It is said that when he was about 20 years old, he was not very good. Later, he gradually matured and became so charming that many people did not even have the courage to pursue it.

However, no one expected that it would be a young boy who came to the stage to give a lecture.

This suddenly caused whispers below. The several student union members who stopped Bai Song last time had their eyes wide open!

This is really a teaching assistant!

Bai Song looked at several members of the student union with a smile, which made several freshmen feel terrified.
