The floor below the bed should be where the woman was talking about.

Ouyang Ping and Guo Lao squatted on the floor, and the others stood behind.

Probably due to the passage of time, the surface of the floor has been worn out so badly that it has cracked in some places, and there are some long grooves in the joints between the floor and the floor. Is it any wonder that it takes a long time to mop the floor? No matter what kind of liquid it is, especially blood, it can't be cleaned up without a few wipes.

The woman stands at the door of the meditation room.

"Is this the place to mop the floor?" Ouyang Ping turned his head to look at the woman and said.

The woman walked over to the bed: "Here it is—right here." ”

Ouyang Ping took off the electrician's knife from the keychain, and scraped the surface of the floor, the cracks of the floor, and the grooves of the joints one by one, if Wang Hongbao and his wife wiped the blood stains on the floor, then it was difficult for them to wipe them clean, because the blood stains would penetrate into the cracks of the floor and the grooves of the joints, and the blood stains on the surface of the floor were relatively easy to clean, and the cracks and grooves of the joints could not be wiped clean. The reason why Ouyang Ping scraped the cracks and seam grooves with the tip of an electrician's knife was to see if there was any blood in the scraped powder.

There are places on the floor, especially in the cracks and grooves in the joints, that are rotting badly. Three minutes later, a small pile of powdery brown objects had gathered on the floor.

Han Lingling took out a plastic bag from her bag.

Ouyang Ping uses an electrician's knife to pinch the powder into a plastic bag.

Guo Lao took the plastic bag from Ouyang Ping's hand, put his nose to the mouth of the bag and sniffed it.

Everyone focused their eyes on Guo Lao's face.

"Old Guo, how is it?"

"Smell it." Guo Lao handed the plastic bag to Ouyang Ping's hand.

Ouyang Ping sniffed, then handed the plastic bag to Liu Dayu, and Liu Dayu handed it to Chen Jie after smelling it.

"It smells a little bit of blood." Chen Jie looked at Guo Lao and said, "Guo Lao, am I right?" ”

Guo Lao, Ouyang Ping and Liu Dayu nodded at the same time.

There is a straw mat on the bed, Yan Jianhua unveiled the straw mat, under the straw mat is the bed board, there are three cracks in front of the first bed board, the color inside the crack is different from the color of other places, and the color inside the crack is a little black.

"Look—" Yan Jianhua said loudly.

Guo Lao lifted the bed board, put the crack in front of his nose and sniffed it, then looked at Ouyang Ping and said, "The smell of blood here is heavier, you smell it-"

Ouyang Ping put his nose to the crack and sniffed: "There is indeed a relatively heavy smell of blood." ”

Ouyang Ping motioned to Yan Jianhua to open the mouth of the plastic bag and place it under the crack, and then slowly scraped the black substance inside the crack into the plastic bag with the tip of an electric knife.

In the process of Ouyang Ping's scraping, two fat bed bugs crawled out of the cracks, and common sense tells everyone that bed bugs are very interested in human blood. Bed bugs only like fresh blood, and once the blood clots, there's nothing they can do about it.

Chen Jie put the bed back in its place, then spread the straw mat on the bed board, he put his eyes on the straw mat, what is Chen Jie going to do?

Since there have been people sleeping in this bed, there should be a few hairs left, if a few hairs can be found, plus the blood samples extracted, they will definitely be able to detect their DMA, in Guo Lao and Ouyang Ping's opinion, their DMA and "9. 27 "There must have been some kind of connection between the DMAs of the deceased in the headless case.
