Afterwards, Xu Yao raised a fist and smashed it directly on the floor. When he raised his fist, it was already covered with blood.

Xu Yao raised his head and looked at the moving figures in the living room. He had an extremely powerless feeling. The murderer was in the living room, but there was no camera. He could only rely on his sharp observation ability to check the different directions of the people in the living room.

In just two minutes, Chen Xinli was poisoned under Xu Yao's nose.

Recalling the experience just now, it was indeed Du Xueming who turned around and went to the kitchen. The process of pouring water was clear, and then he walked through the crowd with water and came to Chen Xingli's side.

He didn't stop at all in the middle. If this wasn't done by Du Xueming, who else could it be?

Liu Xiaobo saw that Xu Yao's palm was bleeding, and said with concern,

"Captain Xu. Your hand is bleeding, hurry back to the room, I will bandage it for you."

"Check all irrelevant personnel carefully and send them out, seal off the scene, and start working as usual.

Liu Xiaobo, line up everyone in two rows for body searches. Since Chen Xinli is drug poisoned, check if anyone has the drug on them."

Xu Yao arranged the work weakly. He had never felt such a serious sense of frustration.

Since he became a policeman, he has always believed that he is very capable, and every time he can solve the case perfectly.

Now, five people have died in the 20 days since he came to the island, the murderer has not been caught, and people are still dying.

What's more infuriating is that today a death show was staged in front of her.

All Xu Yao could do was to look at the death scene helplessly and pound the floor angrily.

Liu Xiaobo searched everyone one by one, but found nothing. He also searched his fellow police officers who had dinner together today, but found no effective clues.

Xu Yao suddenly felt that the air in the living room was extremely thin. He was a little breathless and staggered out the door.

"Liu Xiaobo, you will be in charge of the scene for the time being. Don't miss any clues. Report to me if you have any clues. I'm going out for some fresh air."

Liu Xiaobo nodded immediately, "Yes, Captain Xu, please don't put too much pressure on yourself."

Xu Yao waved his hand weakly, walked out of the villa, walked around the garden, and came to the reef by the sea.

Xu Yao looked at the sea with melancholy, his brows were unmovable. He took out a notebook from his pocket, took out a pen and wrote two English letters "YM" word by word.

What does it mean? An abbreviation of a name or a place name?

The ringing of the mobile phone pulled Xu Yao back to his thoughts, and he picked up the phone. It was Liu Xiaobo.

"Captain Xu, we have already carried Chen Xinli's body to the temporary morgue. Sister Ya asked me to tell you to go over there.

Because of the crime, the flow of people in the living room was so busy that we couldn't get any important clues."

Xu Yao replied weakly, "I know, it's expected that there are no clues.

The murderer was confident that you wouldn't be able to find the clues before committing the crime."

Liu Xiaobo couldn't help but exclaimed, "Captain Xu, I feel that this case is too difficult. We have tried our best, almost 24 hours a day, but we still can't catch Chen Xinhua.

But why did her body suddenly appear today? Logically, Chen Xinhua has not killed all the members of the Chen family, and she can't commit suicide.

Could it be that Chen Xinhua was murdered?"

Xu Yao did not say that he received a threatening message, after all, the person behind the scenes kept rushing towards Xu Yao.

Xu Yao said: "In this case, you should interrogate everyone who has been in the living room at once and find out the suspicious person.

I will go to meet Lin Yalin right now."

Xu Yao's head began to hurt again, but he endured it. He could not relax until the case was solved.

After walking for five minutes, Xu Yao arrived at the temporary morgue. As soon as he entered, he saw Lin Yalin busying herself.

"Sister Ya, thank you for your hard work. Was Chen Xinli poisoned?"

Lin Yalin used her white-gloved hands to pry open Chen Xinli's lips.

Although no toxicology test has been conducted yet, the symptoms of poisoning can be seen from the surface.

Autopsy findings: There is ferricyanide hemoglobin formed in the blood, so the body spots, muscles and blood are bright red. The deceased's organs showed obvious signs of suffocation.

Those who died of hydrogen inhalation poisoning had congestion and edema in the brain, hippocampus, striatum, and substantia nigra, degeneration and necrosis of nerve cells, proliferation of collagen cells, and edema of the heart, liver, and kidney parenchyma cells.

It can be inferred that Chen Xinli was poisoned by hydrogen."

Xu Yao walked to the side of Chen Xinjiao's body again and turned back to ask Lin Yalin, "What about her? Is it confirmed?"

"The deceased had severe edema and emphysema in the lungs.

Due to the inhalation of a large amount of drowning fluid, the alveolar wall expanded, ruptured and bled, and the lungs may be edematous and emphysema. The edges of the lung lobes were blunt and round, and there were rib pressure marks and suffocation punctate hemorrhages on the lung surface.

The blood in the left and right hearts changed and the aorta lining was stained red; diatoms were found in the heart, liver, kidneys and other internal organs.

Chen Xinjiao had multiple collision scars on her body and head. The world has not yet determined whether they were physical injuries or some characteristics of the injuries lost due to the flushing of running water.

The corpse may also collide with rocks, stumps, etc. in the river in the running water, causing injuries, especially to the head."

"Sister Ya means that we can be sure that Chen Xinjiao drowned, but we cannot be sure whether she committed suicide or was killed by him, right?"

Lin Yalin nodded.

Xu Yao stood beside Chen Xinjiao expressionlessly, his mood was very complicated. He had been trying his best to find Chen Xinjiao, but the final outcome was not to see her body.

Chen Xinjiao absolutely could not have committed suicide, so it is very likely that her value of use has been exhausted, so she was abandoned by her accomplices.
