Old Black leaned against a round table in the room, and the place of death was in the dining room of the house, directly opposite the door.

The door had been locked, Xu Tian and Teacher Jin immediately went separately to check the window, and as expected, there was a murder in a closed room.

"It's the same as Lao Li's house, you can't go around the backyard." Xu Tian said.

Teacher Jin didn't say a word, kicked and shattered a glass of the door, reached in and unlocked the door from the inside of the door.

At this time, Xu Tian ran outside the yard and looked around, there was no one on the street, but at this time, the chimneys of every house were very calm, and Xu Tian felt strange from noon, no one here seemed to make lunch.

Lao Hei's death scene is somewhat similar to Lao Li's death scene, it is very calm, there is no trace of a fight in the house, the most important thing is that Mr. Jin, who has not yet entered the house, feels a little strange, and the floor tiles of Lao Hei's house seem to have been cleaned.

Mr. Jin remembers very clearly, when he first entered Lao Hei's house, he felt that the house was very dirty, and there was no paved stone slab or other road in Lao Hei's yard, the light rain last night had not completely dried up, and everyone's soles were not very clean, and there were many people who had been to Lao Hei's house, and those who carried the body of the team leader had gone in before, so it stands to reason that the floor tiles in Lao Hei's house should be very dirty.

"Teacher Jin, how is it?" Xu Tian rushed over and asked.

"It's not easy, you see the inside of this house, it looks like it's been cleaned, and it's just after we left." Teacher Jin said.

Xu Tian cautiously walked into the bedroom along the root of the wall, the body of the team leader was still on the old black bed, but Xu Tian clearly felt that the body of the team leader seemed to be concave.

"Come on in, there's a change in the leader's body." Xu Tian greeted Teacher Jin.

Teacher Jin immediately followed Xu Tian into the bedroom, and the two of them lifted the team leader's shirt together, and at this time, the team leader's chest had completely collapsed, as if he had been hammered with a large blunt object.

"The tissues in the chest have been loosened, what kind of deep hatred can lead to such a treatment of a dead person!" Teacher Jin sighed.

"The floor tiles in the room are also very clean, and they should be cleaned with the wet mop in the corner." Xu Tian pointed to the corner of the wall and said.

"What prompted the mopping man to clean the room? Or is it cleaned by the old black? Teacher Jin said suspiciously.

"I think the probability of the murderer cleaning the room is relatively high, you look at those big footprints in the yard, plus what you heard from Zhao Laohan about the big footprints of the dog god when the previous village chief was killed, it is obvious that the murderer put the responsibility on the dog god." Xu Tian analyzed.

"There is some truth, but I can't conclude yet, how did the murderer lock the door after cleaning the room? It's also a mystery, it's a murder in a locked room, and the killer is guilty of torture. Teacher Jin said.

"I think the murderer's method of locking the door should be more straightforward, you see the two doors of Lao Hei's house, there is glass installed on them, as long as the glass is removed and the door is locked and reinstalled, if it is a worker who is familiar with building materials, this kind of small work is the same as a locksmith changing locks, and it will definitely be done in less than a minute." Xu Tian said.

"Your analysis has some truth, but don't forget, although we can't contact the police now, are you sure that the murderer? It seems easy to change the glass, but the murderer will definitely leave fingerprints on the glass, and if you look closely at these two glasses, there is no trace of being wiped at all. Teacher Jin pointed to the glass and said.

"That's true, this matter was successfully dumped on the dog god, and the cause of Lao Hei's death was too strange, it didn't seem to be injured." Xu Tian said.

"I haven't looked at the body yet! Hurry up and take photos and videos for forensics, you still have electricity on your phone, right? Teacher Jin asked.

"Don't worry! With my previous experience, this time I had enough power banks in my luggage. Xu Tian said confidently.

"That's good, you video collect evidence, and I'll do an autopsy." Teacher Jin said, and put Lao Hei's body on the floor tiles.

Teacher Jin pressed Lao Hei's chest and didn't find anything abnormal, but when Teacher Jin moved his hand to Lao Hei's abdomen, he obviously felt that Lao Hei's abdomen seemed to be a little empty.

"This ...... Could it be ......," Xu Tian said in surprise while holding the mobile phone in the video.

When Mr. Jin unbuttoned Lao Hei's shirt, both of them were shocked, Lao Hei's abdomen had been hollowed out, and even the blood stains were gone, and now Lao Hei was like a poultry with hollowed out of his internal organs.

A large piece of cotton was stuffed into Lao Hei's abdomen, and it was obvious that the prisoner was trying to stop the blood that was flowing from Lao Hei.

"It was only about forty minutes from the time we finished examining the body of the team leader to just now, and when I came back from the other side of the village just now, I deliberately glanced inside when I passed by Lao Hei's house, and I didn't notice those big footprints in the yard at that time." Teacher Jin said.

"It takes less than a minute for you to walk past Lao Hei's house to the entrance of the village by the sea, and we came to Lao Hei's house after a few words, and it was only four to five minutes at most, and the big footprints in the courtyard looked like someone was standing on a relatively dry ground and drawing something like a tree branch, and this person's drawing skills were comparable to that of a student at the Academy of Fine Arts." Xu Tian said.

"But the time when Lao Hei was killed must be pushed forward a lot, the process of cutting open Lao Hei's abdomen is very troublesome, the human body is not like poultry with very little blood, if you cut open Lao Hei's abdomen, there will be a lot of blood flowing out, but there is no blood left at the scene, and Lao Hei's abdomen seems to have been deliberately dealt with by the murderer, and now there is not much blood left in Lao Hei's abdomen." Teacher Jin said.

Xu Tian and Teacher Jin immediately searched Lao Hei's home, but found no blood stains and internal organs.

"Lao Hei's blood and internal organs were taken away, and disappeared at the scene of the crime like Lao Li's severed hands." Xu Tian said.

"There is also the team leader, I think it's very strange about the team leader's car accident, and the team leader was abused in Lao Hei's bed, it seems that the murderer seems to be targeted, Lao Li's hands, the team leader's chest, and Lao Hei's abdomen." Teacher Jin analyzed.

"Plugs! When he found out that Lao Li was dead, he said some strange things, as if he was saying that he had seen such a situation before. Xu Tian said.

"Hurry up and find the plug!" Teacher Jin said.

The two of them immediately rushed out of the door and went straight to the bolt's house, and there was still no one on the street.
