"If you talk about it in chronological order," Zhao Yu pointed to a certain place in the small notebook and said, "Naturally, this is the case! The demon case, at least 15 years have passed, right?"

"Yes!" Miao Ying nodded in agreement, "SARS also broke out that year, right? I sometimes wonder if it was because of SARS that this case was affected?"

"It's hard to say, I've also checked, SARS started in November, and this case started as early as the summer of that year!" Zhao Yu shook his head, "It's just that at the beginning, it didn't attract much attention!"

"Demon case!" Miao Ying said solemnly, "Actually, it should be called a super-large series of suicide cases! I really don't know, why do people have such a name?"

"I don't know, maybe, people can't think of a better term for such an unbelievable thing, so they can only use 'demon' to represent it, right?" Zhao Yu said, "In the same area, in a relatively short period of time, there were 9 suicides one after another, and there is really no way to explain it by coincidence!"

"Yes, the age, gender, occupation and family conditions of the deceased are all different, and there are no obvious mental problems, such people have committed suicide one after another and ended their own lives, it is really incomprehensible!" Miao Ying said, "The headless female corpse case was once recognized as the first unsolved case, mainly because the time span is too large!"

"And this serial suicide case, but the difficulty lies in the means of committing the crime?" Miao Ying sighed, "If you use suicide to explain, there is no way to explain that all nine people committed suicide! But if you use murder to explain, you can't find any clues and evidence! It's really difficult enough!"

"There is a psychologist in our special investigation team, and I also asked her about this!" Zhao Yu suddenly mentioned Wu Xiumin, "She said that if you want to make a person commit suicide by relying on psychological suggestion or hypnosis, it is not impossible to do it, but the probability of success is very small! This is closely related to a person's mentality, willpower, living environment and other factors, there are too many variables, even the world's top psychologists, it is impossible to make 9 people commit suicide in a row!"

"That's right, I did think about the possibility of this kind of psychological hypnosis killing people before," Miao Ying said frankly, "However, in addition to these, maybe there are other possibilities, such as some kind of hallucinogens unknown to human beings, or other drugs that can make people depressed, etc.......! Well...... Like 'oblique' teachings and so on?"

"Well, I'll go back and list it, and when I get back to the Criminal Hall, I'll start applying for this case and re-investigating!" Zhao Yu nodded.

"This case is different from the others," Miao Ying reminded, "Although this case has a very big impact, it has not been officially filed with the police, so the information about that year is also the least one!

"It's okay, the headless female corpse case has been solved, what are you afraid of?" Zhao Yu gently hugged Miao Ying and said with a smile, "You should do it as soon as possible, I look forward to being able to combine my swords with you!"

"Hmm!" Miao Ying also hugged Zhao Yu tightly and said, "Over there in the Criminal Hall, my father has already said hello!

"Heh, if you want your father to hear this, do you have to scold you for turning your elbow out?" Zhao Yu smiled, "By the way, just talking about the old man, I don't know, who is my mother-in-law?"

"Mrs. Kuo!" Miao Ying said casually, "In the past, the Ministry of Foreign Affairs retired from the official position, which was not small. However, seeing that my dad is really busy, naturally the husband and wife are following!"

"Oh......" Suddenly, Zhao Yu remembered the previous incident of eavesdropping on Miao Ying's phone, no wonder, in the phone, Miao Ying's mother's tone was so big!

"Our family's hometown is in the capital!" Miao Ying said, "The reason why we settled in Qinshan is because Qinshan has a lot of friends from my father who can take better care of me!"

"When I was a child, I never understood why they didn't take me to live overseas, why they couldn't accompany me every day, and when I grew up, I realized that the nature of their work determined my loneliness. However, I know that they are also for my good!" Speaking of this, Miao Ying couldn't help but sigh softly in Zhao Yu's ear and said, "Actually, it's better this way! At least let me meet you bastard!"

"Hmm......" Zhao Yu itched, and the heat rose sharply, "Okay, then let you experience it, bastard......"

With that, the two rolled into the sheets again......

......

In the next few days, Zhao Yu and Miao Ying were like glue again, and they reluctantly dated a few times. The last time, they even broke the rules and went to the beach in Wellington to have a good time......

However, time was short, and even if he was reluctant, Zhao Yu finally had to leave first. The embassy helped him and Su Jinmei handle the relevant matters, and on a sunny morning, they took a special plane back to the capital together.

Before leaving, Zhao Yu and Miao Ying naturally kissed me again, Miao Ying promised Zhao Yu that she would do her best to deal with her problems, return to China as soon as possible to reunite with Zhao Yu, and investigate those super big cases together!

Since Miao Ying's identity has been kept secret, none of the accompanying Su Jinmei and even Ma Runkui and others have seen Miao Ying, and Zhao Yu has not told them about it.

Because of this, on the plane back to China, Su Jinmei has always been very curious, and she doesn't understand why Zhao Yu is like a different person, so festive, so smiling!

After returning to the capital, as soon as they got off the airport, they were directly taken to the Central Criminal Department, where they met with Director Jiao Guofeng and even the head of the department.

The two leaders learned about the specific situation and asked them to sign several confidentiality letters, which officially indicated that the New Zealand incident could come to an end!

However, the hall master naturally already knew what was powerful, so before leaving, he called Zhao Yu aside alone and praised him.

The director also said that according to Zhao Yu's excellent performance, he will also consider giving Zhao Yu a promotion and job transfer.

In other words, Zhao Yu has a great chance in the future to become an official staff member of the Criminal Department, and he is no longer a small policeman in the Rongyang Branch of Qinshan!

However, Zhao Yu has now obtained Miao Ying's whereabouts, and he doesn't care about these job titles and other things.

At this time, in addition to praying for Miao Ying's early return, there is only one thing that is the most important, that is, to apply for an investigation of the demon case in the northward migration area.

Therefore, after the hall master left, he immediately found Director Jiao Guofeng and submitted an application to her for investigation. Director Jiao also didn't expect Zhao Yu to be so dedicated, and while praising him, he happily approved the investigation application.

However, although the director had approved it, as Miao Ying said, because no obvious traces of murder were found in this demon case, it was not really filed until the end.

Strictly speaking, this case is not an unsolved case! If you want to re-investigate such a case, it will not require a lot of preparation like the headless female corpse case. All it takes is for the Criminal Department to notify the local police and provide resource support for Zhao Yu's special investigation team.

However, because of this, the information and clues about this case are also the least among the five unsolved cases!

At the time of the 03 task force, the case had just happened, but Captain Jin and the others still hadn't found out the truth. Therefore, after many years, the difficulty of investigating this case again can be imagined......
