Villain: Without Morality, You Will Not Be Kidnapped!

Wang Yuqi: I will conduct a psychological analysis of the crime scene and try to find some breakthroughs in the behavior of the arsonist.

In the next few days, the investigation team carried out intense and orderly work. Through investigation, Li Hao discovered that this mysterious figure was named Zhang Xiang. He was an unemployed construction worker and had a previous record of arson.

Lu Ting used technical means to further analyze the video, and she discovered some details hidden in the image. The person who was originally thought to be wearing black was actually wearing a wig and sunglasses, and was very cleverly disguised.

Qi Lin: It seems that our suspect is very good at concealing his identity, but I believe we can find more evidence. Wang Yuqi, have you found anything in your psychological analysis of arsonists?

Wang Yuqi: Judging from the crime scene, the arsonist may have a strong desire for control and revenge. Arson is often an extreme form of expression that not only causes panic and destruction, but also brings some sense of satisfaction to the arsonist.

Qi Lin: These clues are valuable, but we need more evidence to ensure that our suspicions are correct. Lu Ting, have you found any other videos or physical evidence?

Lu Ting: I have tried various methods, but so far I have not found any other videos related to the suspect. However, I found some residual chemicals at the scene, which may be accelerators used in arson. I will send the sample to the laboratory for analysis, hoping to find more clues.

Qi Lin: Very good, keep working hard. While waiting for the results of chemical analysis, we cannot relax our surveillance of Zhang Xiang. He has a previous record of arson and is likely to do it again

A few days later, the chemical analysis results came out. Lu Ting hurriedly handed the experimental report to Qi Lin.

Qi Lin: What is the analysis result of this chemical substance?

Lu Ting: After analysis, we confirmed that this is a common flammable liquid mixture. It is widely used in the construction industry as an accelerator and cleaner. Based on the comparison, we found a possible purchasing channel.

Qi Lin: Very good! We now have more concrete clues. Li Hao, go and track this purchasing channel. See if you can find transaction records related to Zhang Xiang.

Li Hao: I understand. I will investigate as soon as possible.

A few days later, Li Hao returned to the investigation team office with important investigation results.

Li Hao: According to my investigation, we found a small building materials store that once sold similar chemicals to Zhang Xiang. Moreover, the store owner also provided information about Zhang Xiang's recent residence.

Qi Lin: Great! We are one step closer to arresting the suspect. Get ready for action, we will go to Zhang Xiang's residence to arrest him.

The investigation team immediately launched an operation and went to Zhang Xiang's residence. When they broke into the apartment, they found a secret room filled with arson-related information. Zhang Xiang was arrested and taken to the police station.

During the interrogation, Zhang Xiang admitted his crime and revealed his motive for arson.

(Dehao Zhao) It turns out that he once worked in this building, but he was resentful because of wage arrears and unfair treatment.

Arson became his way of revenge and an outlet to vent his inner anger.

The cracking of the poisoning case made Qi Lin famous and became a detective in the eyes of everyone. All kinds of bizarre cases began to come to his door one after another, and Qi Lin always faced the difficulties and tried his best to find the truth.

One day, I received a rather bizarre case.
