The two clues provided by Bai Song have achieved considerable results.

The first one is about the "big talk" of the third brother. After checking with him, it was found that there were indeed some illegal resale of banned chemicals. The control of chemical drugs is not as strict as that of precursor chemicals. Some ordinary restricted chemicals will face more administrative penalties.

The identity of this person has been verified. He is just a lazy gangster who makes money by doing all kinds of illegal means. He has been detained twice for disturbing public order and once had a history of fraud, for which he was detained for fifteen days.

Original name: Chang Cheh.

The inquiry into Zhang Che was quite detailed, but Bai Song was somewhat surprised that this person actually had a nice house and seemed to be a gangster who knew how to live? This was quite rare.

But considering that he sometimes does some legitimate business and does everything for money, it is not difficult to explain that he has a house. After all, housing prices were not too expensive in the past few years.

From him, we found out about the management problems of chemical raw materials in several chemical plants. In theory, a considerable number of chemical products are strictly managed, but insiders still have their own ways. At present, we have found a batch of illegal transportation problems of potassium hydroxide and acetonitrile. (Note: Basic knowledge, not confidential, editors should not be careless)

Following this line, Captain Li has found a suspected hideout, but no one has been entering or leaving the hideout recently, so it may have become stagnant, so there is no need to alert the enemy for the time being.

The second is the search for slimming drug advertisements in Internet cafes and other places. Several phone numbers and their affiliations have been found. Now the specific people have been identified, which is part of the people we are going to arrest today. There is no evidence to prove that these people have a definite relationship with that place, but one of them matches Geng Nan's confession.

After the cases of Wang Ping, Chen Xiaoli and others were gradually concluded, Geng Nan could no longer hold it in. Many things had nothing to do with him, but he still had to tell the truth. Geng Nan truthfully confessed the supplier from whom he bought the goods.

There are quite a lot of people involved in this case. Sibutramine is a simple thing, but without a special production line, it is impossible to make it in the laboratory.

For example, in our laboratory, we produce oxygen by catalyzing hydrogen peroxide with manganese dioxide or directly heating potassium permanganate. If this was done industrially, we would lose all our money.

Industrial oxygen production is to directly liquefy air at low temperatures and then slowly increase the temperature to separate it.

On the other hand, once sibutramine involves the production line, the output will not be something that people like Geng Nan can handle. The upstream crime may involve more things.

Captain Li also communicated with the criminal police and finally decided to arrest him.

Including Chang Cheh ("Third Brother") and all these small fry, arrest them all, and at the same time, control that den.

I had a meeting today, but basically nothing can be done. This case will definitely take us the whole day. It's already afternoon, and some people are hard to arrest. It's better to rest early and come early tomorrow morning and start then.

However, not everyone took a break. Li left three people behind to catch the thief in the afternoon.

…

After finishing the meeting with Chief Li, Bai Song also caught up with the progress of the case and still focused his energy on today's duty.

In the evening, Bai Song found Ren Xu.

"How does it feel to be the director?" Bai Song asked.

"Sheriff!" Ren Xu was shocked. How could he be the chief?

"You still know you're the sheriff?" Bai Song looked at Ren Xu's tired face. "Just because you're the sheriff, you're smarter than everyone else? You have to ask more questions and learn more about everything. Aren't you afraid of exhausting yourself? Why do you worry so much?"

"I..." Ren Xu felt a little aggrieved. Is there anything wrong with him doing his job conscientiously?

"Your task is to learn from me. Watch what I do and then do the same thing in the future. It is necessary to take the lead when encountering major events, but it is not okay to take care of every detail. You will not have enough energy. Also, you should have more trust in your comrades." Bai Song felt like he was taking on an apprentice.

"Hmm..." Ren Xu seemed to understand but not quite.

Ren Xu was just a simple-minded person. Today, he was even more tired than the last time he was on duty. Even if it was an old policeman dealing with a family dispute, he would ask if it was resolved after he came back, running around.

"Okay, take a break first. The police will arrange for the rested people to go out on duty. You still have to watch the first half of the night until 4:30." Bai Song said, "Last time I told you to keep an eye on the Sibutramine case. I see that you have been focusing on the team recently and have not been on that case."

"Ah..." Ren Xu naturally knew about this. Last time, he and Bai Song worked all night on a case. After they found out about Wang Ping and Chen Xiaoli, Bai Song let him rest for two days. After that, he was busy with the team's work and really had no time to go there.

"It's okay. I'm not blaming you. I noticed you were busy." Bai Song asked, "I had a meeting with them today. They will probably start the action tomorrow. I'll also pay attention to the case tomorrow."

"Captain Bai, do you mean that I should go tomorrow too?" Ren Xu asked uncertainly.

"It depends. If you are busy on patrol until after four o'clock today, you can take a rest. If you have nothing to do in the second half of the night, you can go and have a look to broaden your horizons. I think we will be working with the criminal police tomorrow, and we may get some big gains."

"Okay, I'll listen to you." Ren Xu learned slowly, but he realized one thing, which is that he had to know who he was and just listen to Bai Song in everything.

"It's okay, don't be so polite. I won't treat you as a tool. You have to stand up for yourself soon." Bai Song said, "You will be the pillar of Group 4 in the future. I am not as important as you. If I am seconded for two months, my work will naturally be taken care of by other leaders of the institute. If you go out, Group 4 will be missing half of its staff, understand?"

"Yeah!" Ren Xu nodded heavily.

"Calm down, we're just chatting." Bai Song still treated Ren Xu as his own family. What happened in the rice fields beside the Xiangjiang River was a life-and-death friendship. "By the way, I found out the real name of that 'third brother' today. His name is Zhang Che. He's quite cultured, and looks a bit like Emperor Wu of Han, Liu Che."

"Ah? Aren't there many people with the same name as the emperor?" Ren Xu was puzzled: "I see so many people named Heng and Qi. This is normal, right?"

"Uh..." Bai Song asked in a low voice: "Which emperor is called Heng or Qi?"

“???” Ren Xu lowered his voice a little: “Bai Suo, they are the grandfather and father of Emperor Wu of Han whom you just mentioned.”

"Oh oh oh, yes, that's right. Emperor Wen and Emperor Jing..." Bai Song didn't know what their names were, but at least he knew about the Reign of Wen and Jing. However... well, it was still a bit embarrassing, but luckily he was thick-skinned and didn't show it.

"Um……"
