The report sent by the local criminal police department is somewhat similar to the report of previous cases, first of all, it introduces the many vicious homicide cases that have occurred on the train in succession, and the cruelty, complexity, and heinous nature of the murder cases. The leaders and criminal police of the local criminal police department www.biquge.info have attached great importance to it and organized a large number of manpower and material resources to conduct investigations. The report focuses on how dangerous the crime was at the time of the crime, how the murderer was brutal and risked the life of the train passengers, and then went on to describe how the train attendants were not afraid of danger and helped open the door of the toilet of the car at the scene of the crime to lead out the murderer, and how the police officers on the train directly faced the murderer and assisted the colleagues of the special criminal police department to shoot the murderer, and at the same time how to isolate the distance between the murderer and the passengers of the trainIn addition, timely arrangements were made for ambulance medical personnel to rescue the injured who were injured by the murderer, as well as blood donation by the police for treatment, and let the injured out of danger of life, and took the initiative to bear all the costs of treatment.

Seeing this, Ye Yu couldn't help but feel like if he hadn't been involved in this case, he would suddenly think that it was all thanks to these attendants and police on the bullet train that he was able to crack the case and kill the murderer and maintain the safety of passengers. Fortunately, the criminal police in these places are still somewhat conscious, and they can't do it when the murderer's body is pulled away by the research institute, and they still show that this operation was carried out by their colleagues in the special criminal police bureau in some inconspicuous places in the report.

The report then describes what Yeyu is more concerned about, and begins to introduce the identity of the bullet train murderer Chen Gang. After all, the identity of the murderer Chen Gang was the policeman on the train, and they still had the courage to assume their responsibilities in the report, indicating that their management was generally very good, but they were still usually negligent in the management of individual personnel, and did not have enough understanding of the ideological trends and behaviors of these individual personnel, which led to the policeman taking advantage of loopholes and breaking the law, resulting in a series of vicious cases on the train. Then the past of the murderer Chen Gang, the reasons for the crime, and the motive were explained. The murderer Chen Gang was a temporary worker in the police team, and the reason why he was recruited was because Chen Gang's father was an old policeman on the railway, and he died fighting with gangsters in order to protect the safety of a passenger in his early years. In order to take care of Chen Gang's family, Chen Gang was recruited into the police force as a temporary worker after simple training. It's just that the good times didn't last long, two years ago, the wife of the murderer Chen Gang couldn't bear the poverty and heavy burden of the family, so she left Chen Gang with their children, left the family and went to another city to start a new life, and never contacted Chen Gang again. Chen Gang fell into decadence as a result, and also became addicted to drugs at this time.

The report then goes on to introduce this drug, which only appeared in Zhongshan City more than two years ago, and at first appeared very secretively, and the price was very low, and did not attract much attention. This drug can make people's body become infinitely strong after smoking, which can strengthen the body and even have the effect of aphrodisiac, but after smoking, it can also make people hallucinate and addicted, and bring people extreme excitement and illusory happiness. Therefore, this new type of drug has a popular name in the underground market of Zhongshan City, which is called 'happiness'. In addition, this drug will make people bloodthirsty after long-term use, which has become the most direct reason why the murderer Chen Gang created this series of murders. The report describes the increasing trend of this drug, especially the recent discovery that this new drug 'happiness' has become circulating in the underground market of Zhongshan City, and the price has become more expensive, but there are still more and more people who use it, and there have been many vicious injuries caused by bloodlust due to the use of 'happiness'.

The report also made criticism and self-criticism, saying that although some people once discovered that the murderer Chen Gang had the experience of taking drugs, and Chen Gang had sold blood and participated in experimental research in some private institutions in exchange for money, these abnormal behaviors did not attract enough attention and attention, which led to the occurrence of a series of murders on bullet trains. The report also puts forward specific requirements for the next step of work rectification, on the one hand, to strengthen the ideological education of internal police officers, and to investigate the behavior of police officers, so as to eliminate the danger at the source; On the other hand, in response to this new type of drug 'happiness', special crackdown activities will be launched to find out the source of this drug and completely eliminate this type of drug.

Seeing this, Yeyu has basically understood what is going on, and several things he cares about have basically answered, one is that the traces left at the scene of several bullet train cases introduced in the report are consistent with Chen Gang, indicating that several cases are indeed committed by Chen Gang, and the bullet train murder case will not happen again even if it is completely solved. The second is that the mystery of Chen Gang's identity is basically solved from the content described in the two reports, Chen Gang's family does not have the elements of demon beasts, but only became bloodthirsty and transformed because of the use of this new type of drug 'happiness', although the reason for the transformation given by the research is uncertain, but from the current point of view, this is also the most likely explanation. It's just that Yeyu feels sad for Chen Gang's past, and Chen Gang is dead, how will his old mother who is sick in bed face her future life? Thinking about these night rains can't do anything! The third is this new type of drug 'happiness'. The root of all the series of events points to this drug 'happy'! Why can the illusory 'happiness' attract so many people to suck it? Is it really good to be called 'happy'? Perhaps it is that many people use the name of 'happiness' to escape the pain of life and the numbness of reality? The price of 'happiness' at this time is too painful!

The report of the research institute analyzed that the composition of this drug was related to the blood of the demon beast, and it was perhaps necessary for the special police station to intervene in the investigation, but Ye Yu couldn't make this decision by himself, so he picked up the phone and called Team Ye to ask for instructions. Team Ye quickly picked up the phone, and judging from Team Ye's voice, Team Ye was in a good mood, it is estimated that Team Ye's lover is recovering well and will be discharged from the hospital soon. In the past few days, Ye Yu has also called Ye Team to ask for instructions, so when Ye Team first picked up Ye Yu's phone, he thought that it was some trivial matters and told Ye Yu to watch and do it himself, but when Ye Yu replied that the two reports from the research institute and the local criminal police department had been delivered, Ye Team became serious and serious.

Ye Yu first briefly introduced the content of the two reports, and then focused on Chen Gang's life experience, family background and the reasons for the changes in his body that Team Ye was concerned about, saying that Chen Gang's family was not related to demon beasts, and the changes in his body According to the analysis report of the research institute, it was because of the use of drugs that the genetic changes were caused to be able to transform like demon beasts. Finally, Ye Yu gave a detailed account of this new drug, pointing out that the spearhead of both reports finally pointed to this new drug 'happiness'. And explain that the ingredients of this drug contain the blood of demon beasts, and smoking will make people become infinitely powerful and bloodthirsty, these situations may be difficult for the local criminal police department to deal with, Ye Yu said his thoughts and said that it is necessary for the special criminal police bureau to intervene in the investigation of this drug.

After listening to Ye Yu's introduction and analysis, Team Ye fell into thought, and finally instructed Ye Yudao, "Ye Yu, I also think it is necessary for you to sort out and analyze these two reports as soon as possible, work overtime tonight, and write a detailed report material, which not only explains the situation of the bullet train case, but also explains the situation of this drug." Tomorrow morning, you will send the report to the hospital to show me, and I will be almost done with my business. Team Ye said this, smiled and continued, "Your sister-in-law is about to be discharged from the hospital, and I will rush back to the bureau as soon as possible and report this matter to the bureau in detail." '

Hearing Team Ye say that his lover was about to be discharged from the hospital, Yeyu couldn't help but be happy, this is a rare piece of good news in recent times, Yeyu hurriedly replied to Team Ye, 'Yes? That sister-in-law has finally recovered, that's great, Team Ye rest assured, I promise to complete the task at night, and I will send you the report tomorrow morning! After saying that, the two hung up the phone, and Ye Yu looked at the two reports in his hand and began to think about how he should draft this seemingly extremely important case report material.
