The three of them carefully analyzed the case, but in the end, it was found that all the speculations were not substantial. Zhang Shouqin harassed so many female students, but none of them dared to come forward as a witness against him. As for the extra chemicals in the chemistry lab, that's not a big deal. Even they themselves do not dare to guarantee 100% that the reasoning just now is accurate.

And what makes Zhuge Jing feel most troublesome is that Zhang Shouqin is also a silver detective, and the silver detective can check the internal information of the police station at will, if Zhuge Jing forcibly investigates publicly, Zhang Shouqin is likely to destroy all the evidence and traces of the crime immediately. This is also one of the reasons why she wanted to pull Luo Feng and Wang Xiaoshan in the middle of the investigation to secretly carry out an investigation.

Moreover, for a year, even if it was a corpse, who could guarantee that Zhang Shouqin did not dissolve the corpse with some chemicals.

Zhuge Jing glanced at the computer, and suddenly she showed a smile, "I think, we have some evidence." ”

An email was sent to Zhuge Jing's mailbox, which was a browsing record of the police department's database.

"Zhang Shouqin only got the silver detective card three months ago, only the silver detective card can check the police station's files at will, the month he got the silver medal, he searched for the name Liu Xialai every day, and after confirming that the police station did list this as a general disappearance suspect case and temporarily stopped the investigation, he now has to search once a week. Afraid of death, and breaking the law, the personality of this beast is distorted. ”

"With so many flaws, how did he get the silver detective certificate."

"As I said, his silver medal has moisture. He is a silver medal in that special specialty, there is a serious shortage of forensic doctors all over the world, there is an authoritative professor in the field of chemistry who is willing to take the initiative to assist in the laboratory work, the police station is simply a treasure, Zhang Shouqin has mobilized the entire elite university chemistry department to assist the police in handling the case, the police station naturally thinks that Zhang Shouqin is a good citizen. ”

"What's the use of such an expert's expertise? Psychopaths combined with low IQ are simply scum. Wang Xiaoshan suddenly became angry when she listened.

Originally, with a silver detective card, you could ask the police to go to the police station, but once there is a movement on the police side, it will definitely arouse Zhang Shouqin's vigilance. The only way now is to find Liu Xialai first.

"Do you know what to expect?" Zhuge Jing asked Luo Feng.

"Yes."

"Go ahead, notify me as soon as you find it."

"Okay."

Leaving from Liangjingjing Law Firm, Wang Xiaoshan couldn't help but ask, where did Luo Feng want to find Liu Xialai.

"Actually, it's not 100% sure, it's just a hypothesis."

"Hypothetical?"

"According to the information provided by Sister Jing just now, Zhang Shouqin has not left Nangang City in the year since Liu Xialai disappeared, so I assume that Zhang Shouqin is to guard Liu Xialai."

"But Nangang City is so big, where to find it? Do you want to keep track of Zhang Shouqin? ”

"Zhang Shouqin is too timid, and now he is very vigilant, and once he finds out that someone is following him, he will definitely deal with all the criminal evidence. We can only find it ourselves. In the past year, except for attending meetings of the city government, Zhang Shouqin has stayed at the elite university, and the unit can be narrowed from Nangang City to the elite university. When he was in school, the whole school knew that Zhang Shouqin spent 90% of his time in the science and technology building, either teaching students in the laboratory or doing research on his own. ”

"So in the end it was narrowed down to the Tech Building?"

"That's right, and then think about it carefully, it is impossible for Zhang Shouqin to hide a person in the laboratories and offices of other professors, even his own laboratories and offices often have students and teaching assistants in and out, and it is dangerous to hide a person. Zhang Shouqin had to find a place where there were not many people to go and that he could control. ”

"Hazardous chemicals warehouse."

"That's right, in the hazardous chemicals warehouse in the basement of the science and technology building, on the one hand, the school rarely has the opportunity to use hazardous chemicals, so naturally no one will go there, and on the other hand, the use of hazardous chemicals requires the signature of Zhang Shouqin, the head of the chemistry department. What Zhang Shouqin has been guarding for a year is estimated to be a hazardous chemical warehouse. ”

When the science and technology building was empty in the evening, Luo Feng and Wang Xiaoshan went out. Asked Liu Dongsheng in advance to take the door card of the science and technology building, and the road was very smooth, but in the end, Wang Xiaoshan was a little dumbfounded when he arrived at the hazardous chemicals warehouse, the warehouse door was actually locked with a stainless steel anti-theft lock, and it did not make the overall access control system of the science and technology building, even if it was useless with a special decoder for hackers.

"Zhang Shouqin is too afraid of death, based on his IQ, I guess he must change to this kind of physical anti-theft lock, and then take the key in his own hands to rest assured." Luo Feng said as he took out a small piece of iron from his pocket and began to unlock the lock.

After a few efforts, the anti-theft lock opened with a snap, and Luo Feng still has this skill. Wang Xiaoshan thought that the skills of these liars and thieves had all been gathered on Luo Feng, where did this guy learn?

As soon as I entered the warehouse, the pungent smell came to my face, which was already a layer of masks, and the smell of those unknown chemicals was still very strong. This kind of environment is really not much that people want to come. Luo Feng began to regret that he didn't listen to Wang Xiaoshan's advice and brought a gas mask.

Luo Feng turned his head to look, so frightened that he almost screamed, Wang Xiaoshan was wearing a gas mask, "It's your business that you want to be handsome, I'm still quite afraid of death, these chemicals are not good for the skin." ”

Since they've decided to bring gas masks, it wouldn't be good to bring me an extra one. Luo Feng began to scold in his heart.

The two of them started looking for it with flashlights, first to find out if there was a hidden darkroom here, if Liu Xialai was still alive, he must be locked up in a darkroom.

The warehouse is not very large, and I searched back and forth several times to no avail.

All kinds of chemicals are placed neatly, and all of them are sealed and packaged, after all, they are dangerous goods, and the management is still relatively strict.

Many of those boxes and bottles were in English or other foreign languages, and this time Luo Feng learned smartly, so he didn't dare to touch them with his hands or smell them with his nose.

After looking for a long time, Luo Feng and Wang Xiaoshan didn't gain anything. In fact, this warehouse is not very large, and the items are all sealed and packaged neatly, so you can basically see everything clearly at a glance.

Suddenly, Luo Feng found a suspicious place.

"What's wrong?" Wang Xiaoshan found that Luo Feng was staring somewhere.

"The bucket is opened."

Wang Xiaoshan said as Luo Feng pointed in the direction and looked over, it was a one-meter-high barrel. There are three such plastic buckets in the warehouse, and I don't know what they contain, and the lids of the other two have been sealed with edges, only the one Luo Feng is staring at has no edges.

The entire warehouse has been searched, this may be the last chance, Luo Feng put on the gloves prepared in advance, he wants to see what is in the bucket.
