Police Detective

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

???? There is no contraband, but a trace amount of sodium hypochlorite has been detected.

???? This thing is very common, which is the main component of 84 disinfectant.

The main component of 84 disinfectant is sodium hypochlorite, although it is an oxidizing agent, it is not highly oxidizing. However, the hypochlorous acid produced by the hydrolysis of sodium hypochlorite under light conditions will decompose to produce a small amount of hydrochloric acid and oxygen, so it can slightly corrode metals, and can also corrode some adhesives of metals.

????According to the test results, the reason why this board can fall off has a lot to do with the persistent corrosion of hydrochloric acid. In other words, it is not known how many times this place has been disinfected by 84 disinfectant.

???? This is not the inside of the car, why is it so thoroughly disinfected?

???? Bai Song even suspects that what kind of bacterial weapon is being studied in this building!

???? "What's the matter, could this be some secret agency that was washed away by the Dragon King Temple by our flood?" Bai Song asked.

???? Liu Shuyuan shook his head. He knows quite a lot. If this is the case, it is impossible for him not to know.

???? "It's not easy to say that many units that produce drugs or research and develop biological products are also very strict in control of disinfection." said Zhang Jie, who is in charge of laboratory tests.

???? "Well, thank you so much." Liu Shuyuan continued to chat with her. After bringing along the things and a simple report, he set off on his way home with Bai Song.

????...

Back to the unit, Bai Song packed up his things, and it was almost time to get off work, did push-ups in the house, and followed Liu Shuyuan to the evening meal.

???? There are no outsiders today, they are all within the system, and not only the public security system, there are also some government people, the eldest is not more than 35 years old, and they are all young talents.

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

????Because they are all their own, their speech is not so restrained. Liu Shuyuan didn't have Zheng Chaopei's local tyrant's posture. He just found a quiet and big room, but the atmosphere seemed more harmonious.

???? The pleasant dinner ended quickly.

???? This day has been very rewarding. Whether it is in the Criminal Division or having dinner at night, Bai Song has accumulated a lot of popularity. This was also the first time he had some friends outside of the Jiuhe branch.

???? Of course, the Economic Investigation Corps also has it, but as I said before, if you don't do well here, you are not afraid to offend anyone, because there will be less contact in the future. Similarly, there are really few opportunities for future cooperation with friends here.

???? But these people I know today are all comrades in arms who will work together for a long time in the next few decades, and they are closer to the trenches.

???? Having a glass of wine,...

Bai Song took a taxi back home.

???? Since the incident in April, Bai Song has never put himself in a relatively unconscious state.

After arriving home, Bai Song prepared for tomorrow's class, and felt almost done before going to deep sleep.

???? Tomorrow's class is still very important. If we can teach a class in front of so many high-achieving students, if we can win a little applause instead of a boo, it must 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 clean today!" Bai Song was quite speechless when he saw Wang Huadong like this. I have known him for so long, and it was the first time I saw him in a suit and leather shoes! Even at the party last night, I didn't see him so neat.

???? "Isn't this to listen to your lectures, dress more formally, to support you." Wang Huadong laughed and said.

???? "Let's pull it down, if you want to chase someone else's girl, just say it, there are so many things..." Bai Song said sarcastically, "At first glance, you are inexperienced. How can anyone wear a suit to chase people? "

???? "Huh?" Bai Song said that Wang Huadong was really nervous, "really?"

???? "Look at you like that." Bai Song looked disgusted: "However, I asked you about it. This girl is indeed single. Come on."

???? "Do you still have this contact?" Wang Huadong was very happy to hear this.

???? "I called Professor Tang directly to ask. The girl's name is Ding Jianguo. She is 29 years old this year. She is a fellow from Blue Bird City in the second year of her postdoctoral fellowship. Tang said, if I know any young talents. Jun hastened to introduce him, this girl can't be controlled by ordinary people." Bai Song smiled and said, "I just told Professor Tang that you are yours."

???? Wang Huadong stepped on the brakes on the accelerator, the car jumped out all of a sudden and almost ran behind. The rhythm of Bai Song naturally switching between "Old Tang" and "Professor Tang" made Wang Huadong wonder whether Bai Song was ridiculing him or was serious, and cursed: "Damn, are you sick? I haven't Say what..."

???? "Old Tang said that you are good. He originally planned to introduce a returnee doctor to meet with his students. As I said, he didn't make arrangements for the time being." Bai Song interrupted Wang Huadong.

???? "..." Wang Huadong was silent for half a second, "Brother, what do you want to eat tonight, I will treat you."

????......

???? There are more people today. The last courseware caused a certain discussion on the campus network ~www.novelmtl.com~ People are sometimes superstitious and authoritative, even if the same reasoning is true.

???? For example, you are a high school student, you have finished studying electromagnetic radiation, go home and tell your grandpa that the mobile phone actually has no radiation, and there is no high-voltage electricity, he will not believe it. But if the academician said, he would believe it. Even a word of words is not bad.

???? Professor Tang happens to be one of the authorities...

, So several topics are also hot searched on XX and XX.

???? This is indeed a cake that has touched a lot of people, especially some big cakes in the cosmetics industry, but no one came to look for things in today's class.

???? If Old Tang talks about quantum chemistry for one day today, wouldn't it be embarrassing that many people below would not even pick a thorn?

???? Of course, no one thought that Professor Tang never came to today's class!

???? Finding your own post-doctoral substitutes is not good in normal classes. After all, teacher lectures are also part of the job. But Lao Tang's position is obviously not restricted, and the school administration department does not manage such open classes on weekends.

????Moreover, Ding Jianguo is well-known in the school, a beautiful doctoral student. Oh, no, now I have graduated with a Ph.D.... This is also a legend. It is said that when he was about 20 years old, he didn't do anything. Later, he gradually matured. The charm made many people lose the courage to pursue.

???? However, no one thought that the lecturer was a young boy.

???? This suddenly caused the following whisper. The eyes of the few student council members who stopped Bai Song last time were straight!

???? This is really a teaching assistant!

???? Bai Song looked at a few students from the Student Union with a smile, and saw that some of the freshman children had straight hair.
