People need to demonstrate their own value.

It’s not that Bai Song doesn’t want to be a tool to check houses and buildings, but he really likes to look at the summarized intelligence and then analyze and handle cases. This is what he is good at.

In this case, he could not be the commander. Even Qin Wushuang was just a tool in this case. He was not responsible for case arrangements, but was a member of the forensic expert team.

"Captain Bai, you were just speaking, but there's still a third person who hasn't finished speaking yet." A criminal police officer reminded.

"It's nothing, actually. Thirdly, I just feel that even if Liu Shushu doesn't commit the crime of intentional homicide, she is at least a cover-up. It shouldn't be a big deal to put her under criminal detention, right? The same goes for Guan Shanyue."

"It depends on what the leader decides," said one of the criminal police officers.

…

After Bai Song finished speaking, he had almost finished looking at the evidence in the house. He said hello to the two criminal police officers and left the house.

"What's the next step? Wait for arrangements?" Wang Huadong asked.

"This matter is really strange. Tell me, why did Liu Shushu and Guan Shanyue cover up for the murder?" Bai Song couldn't figure it out. This was a serious murder case. If they were not involved, what would be the benefit of covering up for the murderer?

"So, what is the third thing you really want to mention?" Wang Huadong heard the hidden meaning in Bai Song's words.

"I chatted with Liu Shushu yesterday, and then read her transcript. I feel that she is a thoughtful girl, not a simple one." Bai Song said: "Have you seen her consumption records? Although she earns a lot of money every month, especially during this period, she is not a person who spends money lavishly, which is very rare among young girls.

At least, that’s what I think. This is the third point I wanted to mention, but I guess no one would believe it, so I didn’t mention it. ”

"I believe you. Consumerism is harmful. Too many girls fall into this trap and don't hesitate to borrow money or sell prostitution." Wang Huadong is also a man with sharp eyes: "But Liu Shushu is really not a greedy person. She is multi-talented. Although she definitely likes money, her degree should be much less than that of Lin Mingfei."

"Look at her dress, what level is it?" Bai Song asked.

"Almost the same as you." Wang Huadong was too lazy to even look at Bai Song.

"That's very simple..." Bai Song touched his chin: "Then, if she knew something but covered it up, does that mean it wasn't because of money?"

"It's either for money or for love." Wang Huadong said casually. When he mentioned this word, a beautiful figure naturally appeared in his mind.

"That makes sense. Then who do you think Liu Shushu likes?" Bai Song asked.

"How should I know? Does she like Li Yanan? It's not that Li Yanan is rich, but at least Li Yanan admires her so much, it's hard to say." Wang Huadong analyzed.

"It's possible. Being appreciated by others is a very, very happy thing." Bai Song nodded.

Everyone wants to be recognized by others. In Maslow's hierarchy of needs, this represents the highest level of respect and self-realization.

"If that's the analysis, why did Li Yanan disappear? And why did Guan Shanyue protect him? Who sent the body to the sea?" Wang Huadong asked three questions, and then asked: "Another question is, what about the ether in the room where Zheng Xiaowu died? Where did it come from?"

"Damn! You ask so many questions. If I knew them all, the case would be solved!" Bai Song rolled his eyes at Wang Huadong. "However, the ether you just mentioned is really a big problem. It's been so long since the crime happened, but we still haven't traced the source of this thing."

"Yes! This is not an ordinary chemical!" Wang Huadong said: "This is the first time I have discovered this thing."

Ether itself, although also an anesthetic, is different from many of the chemicals encountered before.

It can not only be used as a raw material for making resins, spices, nitrocellulose, etc., but most importantly, it is a precursor chemical, and can also be used to make smokeless gunpowder in industry. The degree of control is very high. (Note: This is basic knowledge, not confidential, editors please do not make mistakes.)

Therefore, whether this was obtained by Zheng Xiaowu or someone else, it is not a simple matter.

"Don't panic, I think the breakthrough point is with Dahei." Bai Song thought: "If Liu Shushu really likes Li Yanan and is helping Li Yanan to escape punishment, this is not easy to understand. It is unlikely that Li Yanan came here to kill people.

However, if Li Yanan really did nothing wrong and was instead the victim, then there would be no need for Liu Shushu to cover up for her, right?

What a mess...

Let’s first assume that if Li Yanan really killed someone and wanted to escape in this area, it is possible that he was related to Dahei.

I always feel that there is something wrong with this Dahei, but it is hard to say what the problem is.”

"Of course it is. It's not easy to transform from a sales clerk in a pharmaceutical factory to a fortune of tens of millions in just two years." Wang Huadong said, "My family is in business, and business is getting harder and harder. Even if you are a live streamer, you can't make that much unless you are one of the top streamers."

Bai Song nodded. He felt that now all he needed was an opportunity!

…

The phone suddenly rang at an inopportune time.

At this moment, a phone call suddenly came and Bai Song was startled.

"Captain Li?" Bai Song answered the phone, feeling quite confused. Why would Captain Li call him so early in the morning?

"Captain Bai, hahahaha." Li laughed a few times first. From the other end of the phone, one could clearly hear his uncontrollable joy: "Guess, what did we find last night?"

I have known Li Yunfeng for a long time and have worked together with him for many days, but this is the first time I have seen him laugh so wildly.

"Have you found the new base?" Bai Song seemed to have thought of something.

"Yes! Now, we've taken down the entire nest!" Li Yunfeng couldn't hide his joy. "All the people and equipment were taken down overnight yesterday. We seized more than ten tons of various chemical raw materials! In addition, we also seized two special polymer compounds. Can you guess what they are used for?"

"Captain Li, please don't keep me in suspense. My mind is full of the murder case here!" Bai Song pressed his temples on both sides with his thumb and ring finger at the same time, wondering why Captain Li was so childish.

"Color-changing ink!" Li said.

"Color-changing ink?" Bai Song was stunned for a moment and didn't react. Then he looked at Wang Huadong and asked, "What is color-changing ink used for?"

"It seems like it's counterfeit money?" Wang Huadong didn't understand either, but he seemed to have seen it in a TV drama.

Counterfeit money... Bai Song couldn't help but tremble, this matter is really not simple!!!
