After the three returned to the police station, they explained the specific situation to Zhou Qingmin, and whether or not they could determine the target of the next murderer, the police could not sit idly by. As a result of the discussions, it was decided that the protection should be mainly for the academies of the training courses, especially the female members.

Although they didn't get any useful clues, Wang Yi and the others still got a roster for the training course.

The ranking of the participants of the art sculpture course is based on the results of the class, and two-thirds of the members are women. This also greatly increases the difficulty of protecting everyone, in addition to the age level, the group targeted by Wang Yi and others this time is basically between 24 and 35 years old, and there are as many as 7 people.

Because most of the people over the age of 35 are married, there are basically more than two people in the family. Those under the age of 24 are basically college students. For these two groups of people, they can only be abandoned in the current emergency. The most important thing is that the targets of the murderers are basically over 24 years old, judging from the four cases that occurred.

And the assigned protection target is like this, the person Yan Wu is responsible for secretly protecting is Yu Feifei, who is 28 years old. Wang Gang is in charge of Wang Qing, age 27. Wang Yi is responsible for protecting Qian Fang, who is 26 years old. Zhou Qingmin is protecting Ouyang Nuolin, who is 29 years old. Liao Zhixiong is in charge of Zhou Lin, who is 31 years old. And Zhou Yu and Chen Miaomiao are two people in charge of one person, named Li Nan.

After receiving the assignment, everyone began to get busy. Scattered in Changling City, they began to protect the students of these training courses, and all they could do at present was Sima to be a live horse doctor.

But two days have passed, and the murder still hasn't happened. The murderer seemed to have disappeared from it, and at this time, everyone couldn't help but be a little lighthearted. During these two days, everyone was not only tired, but also tired.

On the night of the 17th, that is, at 22:15 on Monday night, everyone was still holding on. At this time, Yan Wu was sitting on the rest chair in the Lijing Garden Community, his eyes were red, which showed that he had been seriously lacking in sleep in the past three days. That's right, who would dare to take it lightly at such a moment. Even if you are a little slack, you will pay attention to it immediately.

Yan Wu has watched all kinds of people enter and exit Building 20 in front of him in the past few days, but he didn't find any particularly suspicious people. But on second thought, aren't most murderers like this? The ordinary is even less likely to attract attention.

Yan Wu kept smoking, trying to make himself sober. Yu Feifei returned to the community at 21 o'clock, through the observation downstairs. Yu Feifei has not come down since she returned home, and the floor house she lives in is also brightly lit, and there is something special about it.

"Well, what day is this a head? It seems that there is nothing going on at night again, this damn murderer. Yan Wu threw away the cigarette butt and looked at his watch, the time was already 22:30. In his opinion, the murderer should not appear again at such a late hour. This is an upscale community, especially for people who haunt at night, and the doorman security should have a special image. Thinking of this, Yan Wu went to the chair, thinking about taking a rest first.

When Yan Wu woke up again, it was already 3 o'clock in the morning. Rubbing his face, Yan Wu looked at his watch and wanted to continue sleeping. But at this moment, when he looked up at Room 506 of Building 20, where Yu Feifei lived, he couldn't help frowning. At this time in time, room 506 is still as bright as day. Today is Tuesday, Yu Feifei should be going to work, why hasn't she rested so late?

"Why, don't have an accident?" Yan Wu suddenly broke out in a cold sweat, depending on what he realized? Instantly lifted his fat body and rushed to the elevator in Building 20.

Room 506, the door is closed. Yan Wu knocked on the door for a long time and still no one responded, which made Yan Wu's heart burst out. immediately took out his mobile phone and called Wang Yi.

"Knock the door open at once, I'll be here now." Wang Yi's voice on the other end of the phone was anxious, and he didn't have time to blame Yan Wu, so he hung up the phone directly.

When Wang Yi arrived at Room 506 of Lijing Garden Community, Yan Wu had been standing in the house for a long time. At this moment, his face was even more ashamed, and Yu Feifei's corpse in the house was lying in the middle of the hall, with a carved utility knife inserted in the heart of her back, and Yin Hong's blood flowed all over the living room.

"The deceased Yu Feifei, the cause of death, the utility knife inserted in the back, directly stabbed into the heart and caused death. The time of death was supposed to be between 21 and 1 a.m. tonight, and the body had a thigh amputated. Judging from the observation at the scene, the deceased should have been stabbed in the back by the murderer when the door was opened, and then dragged the body into the room. There were also traces of the deceased's blood on the door railing, and no fingerprints were left at the scene. Qin Su said in a deep voice after the autopsy.

"It seems that our judgment was correct before, and the target of the murderer is the trainees of the training course." Zhou Qingmin was also pale.

"All that was left at the scene was a utility knife, and it seemed that the next victim was one of them. Could the successive murders of students in a training class be related to their art carving competition? Chen Miaomiao said with a frown.

Wang Yi was also extremely helpless when he looked at Yan Wu's lost soul, even if he scolded Yan Wu at this time, it would be useless. "Tomorrow I'm going to Art Without Boundaries to see if I can find some useful information about this carving competition."

"Wang Yi, no matter who it is tomorrow, if you don't cooperate, you will be directly arrested and interrogated by the police station, and I will bear all the consequences." Zhou Qingmin can't care so much at the moment, and he can't solve the problem if he continues like this.

On the morning of the 18th, Wang Yi came to the Art Unbounded Training Institution, although there is no training course now, there are still staff on duty and some persons in charge. Through understanding, Wang Yi learned that there was only one place in the original art carving training class for this competition. And only those who have the best results in the class can participate in the competition as a representative and pass the observation of the list.

The 5 deceased are all in the top 10 academies, and among these 10 people, there are now Ouyang Ruolin and Zhou Lin, and there are also three students, namely Yu Zhigang, Lin Liyun and Wu Chuanfei.

Since 5 of the 10 people have died, the top five are now Zhou Lin, Ouyang Ruolin, Yu Zhigang, Lin Liyun and Wu Chuanfei, and the next 5 are filled by the original 10.

This clue is important to Wang Yi, and the murderer is likely to be unable to participate in the competition because of his low ranking. So the only way for him is to get rid of the people who are in line before him, so now the next 5 people are the last big targets, and they may also be the most suspected.
