"What does this mean?" Lu Ling asked humbly.

"There is almost no titanium in the human body. Fifty people put together can't collect even one gram of titanium. However, the titanium in the blood of the deceased exceeded the standard. Both of them exceeded the standard, which means that there is a high probability that the drug injected by the murderer

It has something to do with it." Liu Liwen said, "This is not what I said. This was verified by the trace physical evidence, and the report will be sent to the team soon."

"If the medicine contains excessive titanium, what is the reason? Will it increase the toxicity? Is it a heavy metal?"

"No, I also heard what the teacher just said. He said that one of the methods of synthesizing cyanide uses titanium chloride. It is suspected that the murderer made homemade cyanide. The concentration is impure and mixed with some reactants or

Catalyst. You must know that in a few milliliters of liquid injected, there are only a few hundred milligrams of cyanide, and only dozens of milligrams more titanium are needed, and trace physical evidence can be detected." Liu Liwen explained, "Generally speaking, if it is a hospital,

The purity of the cyanide in the laboratory is very high, but if you make it yourself, there will be some messy reactants in it, which is normal."

"So, the source of cyanide is most likely homemade?"

"Yes, and it may be the oxime (wo) dehydration method. The Institute of Criminal Justice is already inferring the reaction equation, and many things can be deduced from it." Liu Liwen looked a little excited.

"Professional!" Lu Ling praised.

Leave professional matters to professionals!

Liu Liwen quickly told Yan Yu about this matter, but Yan Yu was not very excited: "Before the person is caught, all evidence must be considered in two ways. In this case, is it possible that the murderer did it intentionally?"

The flaws left behind."

Yan Yu's words put out Liu Liwen's fire directly, but both Lu Ling and Liu Liwen understood that Yan Yu was just doing this out of habit, not focusing on the situation and the person. Until the case was completely solved, all the excitement was worthless. Yan Yu was not

She thinks this evidence is useless and she takes it very seriously, but she prefers everyone to calm down.

After hanging up the phone, Lu Ling comforted Liu Liwen: "I don't believe this murderer is better than the experts. Yan Yu is just used to that."

"Well, it's okay actually. I just feel like I didn't help much with this case. The forensic doctors here in Shenzhou are very professional, much more professional than those in Liaodong. I basically can't get involved."

"Then you happen to be here to study. I'll sit down for a while. I've been busy with this case and haven't had time to think about it." Lu Ling said.

"Okay, I'll go there first."

...

Yan Yu is now working with Wu Yuqiang to find the deceased's friends to collect evidence.

The person Yan Yu found was Li Zhuoya.

Li Zhuoya has been questioned by the police for two or three hours, and all the basic evidence has been collected.

"This kind of thing is normal." Li Zhuoya still didn't show much expression when facing Yan Yu.

Liu Zheng died, and Li Zhuoya couldn't be said to be too sad, but naturally she couldn't be said to be happy. Although they broke up, after all, she was the one who chose someone in the first place.

"I don't think it's your problem. I think it's possible that one of your friends exaggerated your problem too much?" Yan Yu asked.

"No, I have very few friends." Li Zhuoya shook her head and looked directly at Yan Yu, "Actually, the question you asked was also asked by other police officers just now."

Li Zhuoya was a little helpless. She didn't know much, after all, they had broken up for so long.

Moreover, before this, the questions asked by the police were very straightforward. Basically, how far has your relationship been? How are you? Are you pregnant?

These questions are necessary to help the case, but Li Zhuoya is still a little helpless.

"This is no small matter after all." Yan Yu shook her head gently, showing some interest in Li Zhuoya.

"Yeah." Li Zhuoya nodded.

"How would you feel if you were asked to handle Liu Zheng's remains?" Yan Yu asked.

"Do I have the right not to answer this question?" Li Zhuoya thought for a second and asked directly.

"Of course." Yan Yu nodded lightly.

"I..." Li Zhuoya paused, and after about ten seconds, "He is actually a very serious person. If I were to handle it, I would also help him handle it cleanly. He has had plastic surgery, but because of his

He was so troubled that he only had his nose moved. It’s not that his other facial features were perfect, it was just that he was troubled and didn’t know what was best. If I were to deal with his remains, I think I might even put on makeup for him to make him look decent.

Some."

"Thank you." Yan Yu nodded, then stood up and prepared to leave, "Thank you very much for cooperating with me. Maybe someone will ask you today. I can't change this, but I won't look for you again."

After leaving here, Wu Yuqiang finally breathed: "Sister Yan, do you think there is something wrong with this person? Her ex-boyfriend is dead, and she is a suspect. Why is she so calm?"

"Because she didn't kill the person." Yan Yu said.

"Ah? Why?" Wu Yuqiang was a little confused, "Maybe she is lying?"

"Li Zhuoya lives a relatively transparent life and knows what she is and what she wants. Don't think Liu Zheng is a scumbag. When he is involved in a relationship, he does better than most men, but he

It is true that he likes the new and dislikes the old, and his patience is far from enough. Li Zhuoya can actually see something about people like Liu Zheng. Li Zhuoya is not interested in his money, but also for this kind of emotional experience. Li Zhuoya works as a funeral director and has come into contact with too many people who died violently.

She is very open-minded, and it is indeed unlikely that she will kill someone. She won't be able to think about breaking up." Yan Yu said a long paragraph and explained it to Wu Yuqiang.

"That's it, no wonder... If you ask me to say that it's really tiring to live such a thorough life..." Wu Yuqiang sighed.

"Look at Wang Tongwei, he doesn't live a thorough life, and he is even more tired. Let's go, we have to go find him." Yan Yu said, "He has a lot of things on his mind, but he didn't say that this person buried himself."

"Would he kill someone out of jealousy?" Wu Yuqiang asked.

Yan Yu nodded: "But this is not comprehensive. In this way, you can listen to Lu Ling's analysis of Wang Tongwei."

With that said, Yan Yu motioned to Wu Yuqiang to call Lu Ling.

Lu Ling received the call and paused for a few seconds: "Wang Tongwei is actually a very contradictory person. He is jealous of Liu Zheng. As an ordinary boy, it is too difficult to find a beautiful woman. He must be jealous of Liu Zheng. He is even jealous of Li Zirui.

, because Liu Zheng would talk to Li Zirui first before talking to him about anything. Lao Guo had a cross talk, saying that he wanted Feng Yuqian to be the eldest prince and Gao Feng to be the second prince, but the two of them actually got into a fight. It looked like a cross talk, but in reality

There are too many wins, and the jealousy among the losers is also very serious. Therefore, Wang Tongwei may be more envious of Liu Zheng's jealousy, and envy is not a bad emotion. Therefore, Wang Tongwei may even kill Li Zirui

, they may not even kill Liu Zheng."

"So, Wang Tongwei was not the beneficiary of Liu Zheng's death. If Li Zirui died, Wang Tongwei would be the beneficiary." Yan Yu listened to Lu Ling's words and explained to Wu Yuqiang.

"Is that so...If you say that, why do you want to find Wang Tongwei?"
