The police received a report from the cleaning aunt that a man died in the hot spring of the hotel in a very strange posture.

Due to the high temperature of the hot springs, the corpse was already burned all over the body. According to the hotel manager, the temperature of this hot spring pool is close to 80 degrees, and it is rarely open to the public because the temperature is too high. Usually it is only used as a water source for the hotel's other hot spring pools, so this area is deliberately fenced off by the hotel.

Unexpectedly, this fence blocked the guests, but not the staff of his hotel. The deceased's name is Liu Yong, an employee of the hotel's maintenance department, and because few people come here, there is no surveillance, and the manager suspects that he may have accidentally fallen while repairing the equipment.

When the medical examiner fished up the body, it was determined that it was definitely not an accident, because one of the deceased's eyes was stabbed with a sharp weapon, and the eyeballs inside were punctured.

This was obviously a deliberate means of killing, but the real cause of death of the deceased was scalded to death by high temperatures. The time of death was about eight hours, and there was a mobile phone with water on his body in addition to his clothes.

After investigating the scene, the police officers on the other side found a hemp rope in the hot spring pool. And because of yesterday's heavy rain, there were no useful clues left outside the pool.

The police found an iron lock with a key on the fence gate, and there was no sign of damage to the surrounding fence, so the initial guess was that the murderer was someone from inside the hotel.

But why did the murderer stab the dead in the eye? The police came to the deceased's dormitory to find out what was going on, and according to his roommate, Liu Yong said he was looking for a woman after work yesterday, and then he didn't return all night. And he also received a strange package the other day.

There was a delicate doll in ancient costume, and Liu Yong threw it away in a panic as soon as he saw the doll. After hearing this, Lao Ji immediately came to the garbage station of the hotel, fortunately the hotel is located in a remote area, and the garbage truck does not come often.

After rummaging through the search, the police found the doll, whose legs appeared to have been deliberately broken. After Lao Ji restored his leg, a song began to play inside, and the lyrics revealed some content about the cost and repayment.

Police officer Xiao He recognized the doll as Zhao Ling'er in the fairy sword, and Lao Ji thought that this doll might be the connection between the murderer and the deceased.

After returning to the police station, the forensic doctor conducted an in-depth autopsy on the body and found some residues of sleeping pills in the stomach of the deceased. There are strangulation marks on the wrists and ankles to varying degrees, but none of them appear to have struggled.

Combined with the hemp rope found in the hot spring pool, Lao Ji guessed that the murderer should have given the deceased sleeping pills first, then tied the deceased, then stabbed both eyes, and finally threw him into the hot spring pool.

But the medical examiner was puzzled why the murderer did the ritual act of stabbing both eyes if he was only trying to kill the deceased. Lao Ji thought that this was a vendetta killing, so he suggested that the focus of the criminal investigation direction could be placed on the social relations of the deceased.

Soon the police investigated that Liu Yong had a girlfriend, and Lao Ji immediately led someone to find the woman. His girlfriend said that when she heard Liu Yong call a few days ago, she vaguely heard that he and the hotel manager Cao Dong seemed to have some grievances, and she had never seen Liu Yong since that separation.

Lao Ji followed the clues she provided and took Cao Dong to the interrogation room. Through interrogation of Cao Dong, he learned that he usually played mahjong with Liu Yong, and Liu Zhiyong also brought two friends, one named Fat Cheng and the other Shen Qiang.

In the beginning he was lucky and never lost, but then he didn't know when he started to lose. It wasn't until he was in debt that he realized he might have been scammed by them.

But he already owed money by this time, and it was too late to say anything. So he often went to steal guests' things, but he didn't expect this scene to be secretly recorded by Liu Yong, and he has been threatening him with this video since then.

But he said that even so, he didn't have the courage to kill, and that he went to Didi that night. The police then verified his confession and found that he was not lying, which ruled out the suspicion that he had committed the crime.

At this time, the police received another report, saying that a residential building was on fire, and Lao Ji immediately led people to the scene.

The owner of the burned house turned out to be Sister Gu, a former forensic doctor at the police station, and after investigation, it was found that there was a lot of residual gasoline at the door. Iron chains were deliberately chained to the door, and a dried blood stain was found at the staircase.

Ji guessed that this was likely a premeditated arson, and then the police found a bottle of gasoline and a pair of bloodstained gloves in the trash can downstairs.

In addition, the police also found an unexpected clue, Sister Gu said that on the night Liu Yong was killed, she also stayed in that hotel. And coincidentally, she also received that weird doll.

After getting this clue, Lao Ji thought that the arsonist and the person who killed Liu Yong were probably the same person. The police then checked the surveillance here and found that it was a man who set the fire, but it was too dark to see the man's face.

I only knew that the man's age was about twenty-five to forty years old, but Lao Ji felt very puzzled, the doll that Liu Yong and Sister Gu received before, after a forensic examination, found that the hair on the doll was actually made of real hair. And these hairs all came from the same woman, and since the two cases were related to a certain extent, Lao Ji decided to combine the two cases for investigation.

According to the clues provided by Cao Dong, the police found Shen Qiang's address, but he was not at home. After searching the room, in the corner of the sofa, I found a doll that was also made of real hair.
