Such a big tree must be deeply rooted. If it goes down with a shovel, half of it is soil and half of it is roots. It's very hard to dig.

While they were digging, he walked around the tree trunk. The light of the flashlight shone on the Fu character on the tree trunk. The handwriting was very deep. Even after decades of wind and sun, it was still distinct.

As the excavated soil gradually piled up, the roots of the trees gradually revealed. Jingsa was reluctant to do the work, and he worked very hard. After a while, he was sweating. He suddenly shoveled down and hit something, which made his hands numb.

"What's so hard?" She let go of the shovel and blew the red part of her hand.

Cao Zhen hastened to gather together to come over, "dug?"

She shook her head. "I don't know. It's too dark to see clearly."

She pointed the flashlight at the place where she was digging. The thick roots of the trees were winding long and deep. They were like living snakes sucking the soil. The halo moved slowly at the roots of the trees. Some insects living in the soil were stimulated by the light, wriggling their fat bodies and dying to drill into the soil.

The roots are thin and thick. The thick ones are mostly outside and the thin ones are inside. When jingsa was digging, he scraped off several thin roots, which scattered and fell on the soil. The broken roots were vaguely entwined with something, which tightly wrapped the thing one circle after another.

Hu Hu shone his flashlight up, and his bones were exposed in the light.

"Sure enough

Jing SA is a face black line, "Oh, my mother!" I really got something I shouldn't have.

It was a human skull.

It was tightly entangled by the roots, just as it was entangled by Medusa's hair, lying there powerless and silent.

"Who's so unlucky to be buried here as a nutrient when he dies? It's inhuman."

"Compared with the specimens in the secret room, I think it's better to bury them in this place, at least in the earth."

The fallen leaves return to their roots.

"Cao Zhen, see if you can take out the bone."

Cao Zhen pulled out the root of the tree wrapped around the skull with his bare hands. "It's very tight. I can't take it out without special tools. If it's hard, I'm afraid to destroy the evidence."

This is obviously a human remains, buried under a tree means that this is a murder.

Since it's a murder case, it's better to keep it as it is and wait for the forensic to do it.

Hu Hu came closer. With a flashlight, she shone deep into the root of the tree. The root of the tree was close, and there were some other bones in it, but it was very deep. She was not sure whether it was complete or not. It was because the root of the tree separated the trunk from the skull when it was growing.

"Duanmu, in your opinion, is this a man or a woman?"

Although there is only one skull, that is, the skull, it is not damaged and is very complete. It is not difficult to identify whether it is male or female.

Skull is a very important existence in gender identification, because human face personal characteristics and gender characteristics are obvious, and these characteristics are mainly determined by the characteristics of the skull.

Before the sexual maturity, the gender difference of skull is small. At puberty, the gender difference begins to increase gradually. After adulthood, the gender difference will be very significant.

Hu is not a forensic medicine, but the basic knowledge of forensic medicine is very clear.

"According to the shape, the skull is large, the volume should be about 1450ml, the face is narrow and long, the forehead is inclined, the eyebrow arch is prominent, the orbit is low, slightly square, the upper edge of the orbit is blunt, the mandibular angle is approximately right angle, and the mandibular alveolar is prominent. It should be a man."
