"The murderer is relatively petite. It may be a woman, but it may also be a man. After all, there are many men who are thinner than women. So there is no way to directly determine the gender."

   Judging from the photos, the chest is flat and thin, but it is not ruled out that women dress up as men in order to conceal their gender. But what if the murderer is rampant and doesn't make any cover up at all?

  The corpse can be placed in the victim's residence or in a place where he often goes in such a form. Does this still mean that the murderer is rampant?

   His hands and feet are exceptionally clean, indicating that he has done a lot of study before this.

   "I don't think it's right when I see the possible occupation of the murderer you wrote on it, Uncle Police."

   "The murderer will develop anesthesia by himself, not necessarily a doctor or a pharmacist. He may have learned it himself just because he is smart."

   She has read some books before, many perverts, all of them are very smart.

   According to the data, it seems that the test report of the deceased who started using anesthetics earlier, in fact, the dosage of anesthetics was used more and less often.

  The purity of the anesthetic is not good, it is more like a general sleeping pill.

   This shows that the murderer only learned a little bit at the beginning.

   Then slowly, I started to become more and more proficient.

   There are also some finishing work of the murderer, which is enough to show that he actually knows a lot about the police in solving cases and searching for evidence.

   But this cannot be used to guess that the identity of the murderer is a police officer!

   Now that technology and book knowledge are so developed, the murderer is likely to have learned through these knowledge.

   After five years of slow exploration, the murderer's tactics have reached the level where no flaws are revealed.

   This is one, scary pervert!

   "As usual, the murderer killed two young female victims a year, and the two victims were killed almost nine months apart."

   "But this year is very strange. After killing a victim, the murderer committed another crime within a short period of time!"

  Ling Wuyi turned to face this Yan Qizhen, with a solemn expression: "Uncle police, do you think the murderer has become more rampant and think that he will not be caught by the police at all, so you want to increase the number of victims every year?"

   If that is the case, then maybe there will be a thirteenth victim!

  So, solving the case is imminent!

   Yan Qizhen frowned, his face also very solemn.

  Ling Wuyi said this question, he was already worried when he saw Lin Xiao's body.

  If that's the case...

   "Actually, I'm not sure about the occupation of the murderer. After all, there are so many occupations. We can't say that they are ordinary and useless. Maybe the murderer is a grass-roots worker."

   "He may be a cement stone at a construction site, a white-collar worker in an office building, or more likely, a school teacher who serves as a teacher!"

  Ling Wuyi's eyes deepened when he said this.

   Judging from the fact that both victims were in the same middle school, it should not be a coincidence.

  Ling Wuzhi is still guessing, the murderer is in the school!

   He may be a teacher, a cook in the cafeteria, or more likely, the skinny uncle guarding the campus!

   "I think the direction of investigation should be locked at the school!" Ling Wuyi said.

  Yan Qizhen pondered for a moment, nodded, and agreed with Ling Wuzhi's words.

   stood up from the chair in a hurry, he picked up his jacket and put it on, picked up the phone to make a call, and said something to Ling Wuzhi.

   "I'm going back to the police station for an emergency meeting now. You can stay here, or you can go back first and wait for my call."

  Ling Wuyi stared at Yan Qizhen, who hurriedly left the study, and followed, she wanted to speak, but Yan Qizhen was already instructing the other end of the phone to prepare for the meeting.

   It wasn't until Yan Qizhen went to the entrance to change his shoes that he hung up the phone.

  Ling Wuzhi hesitated for a while, but still asked, "Uncle Police, are you not eating dinner?"

   She's marinating Coke chicken wings...

   Thinking of so many ingredients at home, Yan Qizhen paused: "You can eat first and then go back, or you can bring those things back." It would be a waste to stay with him anyway.

   While talking, Yan Qizhen had already changed his shoes, opened the door with the car key and left directly.

  Looking at the back of Yan Qizhen hurriedly entering the elevator, Ling Wuyi was a little disappointed and whispered.

   turned around and went back to the house.

   looked at the time, it was almost five o'clock.

  There are so many ingredients, Ling Wuyi thought about it, and just made all these things mature!

  Anyway, Yan Qizhen's refrigerator has a great fresh-keeping effect!

   licking off the sleeve tube that did not exist, Ling Wuwei went to the kitchen with full fighting force——

   All the ingredients that can be made are made into cooked food. When Yan Qizhen wants to eat it, just take it out of the refrigerator and heat it up.

   Yan Qizhen's refrigerator is the latest technology, and it is absolutely fresh. It is definitely incomparable with the refrigerator of ordinary households.

  Although Yan Qizhen didn't say whether he would come back for dinner, Ling Wuyi still served two people.

   looked at the time, because I had been busy in the kitchen for too long, it was almost eight o'clock in the evening when I sat at the dining table.

   It was already dark outside, but Yan Qizhen showed no sign of coming back.

  Thinking of the murderer, Ling Wuzhi reckons that it would be good for Yan Qizhen to come back!

   After a pause, he picked up the bowl and ate silently, and then washed the bowls and chopsticks he had used.

   Looking at the meal reserved for Yan Qizhen on the table, after thinking about it, Ling Wuzhi went to the study upstairs to find a piece of A4 paper and cut it into a post-it-sized piece of paper, and then left a message to Yan Qizhen.

   After that, Ling Wuzhi took his bag and left Yan Qizhen's residence——

A few days after   , Ling Wuyi went to the school to do research.

   For several days, she did not find any suspicious person.

  Yan Qizhen is very busy, so busy that Ling Wuzhi has no time to see him.

When    went to school or something, Yan Qizhen asked a little policeman to accompany her.

   This time, Ling Wuzhi didn't complain that Yan Qizhen was too busy, and it was difficult for her to meet him.

   She still remembered that Aijinjin invited him to go to the concert together!

  If Yan Qizhen is really busy, he definitely won't have time to make an appointment!

   Before I knew it, it was the weekend.

  The first thing Ling Wuzhi did when he got up was to find his mobile phone and call Yan Qizhen.

   She read the information that Yan Qizhen sent to her last night, and went to bed very late after reading it.

  So when Ling Wuzhi woke up, it was already nine in the morning.

   The phone was on the phone for a while before being picked up.

"Hey?"

   "Uncle Police, where are you now?" Ling Wuzhi blinked and got up from the bed.

   "I'm listening to a concert." Yan Qizhen's answer was natural, and he added: "If there's nothing else, I'll contact you later."
