The little trumpet nods its head.

“Look at it this way,” Murong Yukawa turned his skull to the side.“The forehead is vertical, the top is flat.The male forehead and top are arced.”

“Can you see her age?”

Murong Yuchuan looked at the teeth of the skull, slightly removed the jawbone, took a magnifying glass from the experimental bench, attached it to the teeth, and looked at it one after another.“The third permanent molar of the skull has grown intact, with little wear and tear, and the roots do not calcify... an adult, but not very old.Her tooth tips are basically flattened, her dentin is very good, and overall, she will not be more than twenty-five years old."

“Oh.”

“Her teeth are clean, no cavities, no dental stones, no plaques.Moreover, her constant grinding teeth wear is less, out of old age, this life before the eating habits are very particular.Even I guess she's very simple and self-disciplined in her life."

“Can you see it too?”Lu Xiaotang slit his eyes to look at Murong Yuchuan.

“I guessed it too.Usually, a girl who likes to eat snacks, a girl who likes to eat a big grin, will more or less have tartar in the gums or at the teeth, and even if he washes his teeth frequently, it will leave traces.He looked at the landing, confident she knew what she meant.

“How do I feel if you’re talking about me?”The little tidbits tucked at him.

Based on past experience, Murong Yuchuan hastened to open the topic.“She rarely or doesn’t smoke, barely drinks alcohol, rarely eats sweets, acidic foods.On this basis, it is estimated that her body should be thin.”

“...”

"From her relatively weak and smooth bone, she is more like a person south of the Yangtze River."I can take some bone samples, and through the genetic marker identification system in the school computer, I can estimate which area of the person is, if I am lucky."

“What if she’s a foreigner?”

"That's complicated."Murong Yuchuan shrugged.“In terms of bone shape, at least she’s Asian or of Asian descent.”

"But, with your eyes, have you found a funny place?"Murong Yuchuan held his skull in front of Lu Xiaotang.

He looked at his head for half a day.“I think it’s normal.There are no scars on them, no residue, and they are clean.”

“Yes, you are right.Don’t you think it’s too clean?”Murong Yuchuan smiled a little.“It is usually only in hospitals or in laboratories that this specially treated bone has such a specially treated bone.”

“You mean it was a skeleton?”That's fine."Lu Xiaotang said.

“I’m not sure.I have to...”

Murong Yuchuan thought about it, picked up an anatomical knife, gently scraped a thin layer of powder on the skull, put it on the slide of the polarized light microscope, and dripped a drop of alcohol.

He turned the knob to the focal length, staring at the barrel of the mirror.

Lu Xiaotang waited for a long time to ask, “Have you found anything?”

"One thing I can be sure of is that this skull has been treated with a certain amount of treatment, so it will be so clean."It is impossible to be a hospital specimen.The production process of medically bone specimens will go through high temperature, disinfection, and remove all muscle fat tissue except bones.There is a large amount of soft tissue attached to the bone membrane on this skull.This is an incomplete process.It also shows that the skull was formed within three years.”

“Three years?”The little twilight took a cold breath.“That is to say, the girl died no more than three years...”

“You can say that.From the moment he died, his body began to rot.This process is called ospicalization.Generally buried in the ground, after two to three years, muscle organs and other soft tissue will become mud-like gray, easy to break away from the bones.If the body is exposed outside, this time will be shorter.”

“It could be from the grave, right?”Lu Xiaotang asked.

Despite the prevalence of cremation in modern society.But in many remote areas still have the old customs of burial.

Yukawa knew what she meant.If the girl to which the skull belonged did not die a normal death, there must be a tragic story hidden.

“There is this possibility.”Murong Yuchuan then said: "I will soon be a check material for the bones, if it is poisoned death, the general toxic substances can be checked out."

He flipped the skull and turned the octagonal hole upward.The smooth incision of the cervical vertebrae is clearly artificially cut.

There were no cracks in the skull, no lumps, and no marks of being hit.

Was the young woman’s head cut off from life?

Lu Xiaotang can also see clearly.She bit her lip and looked at Murong Yuchuan, she didn't want to guess for herself, she had to wait for professional judgment.

Murong Yuchuan took a magnifying glass to carefully observe the break of the cervical vertebrae.“It was cut by metal.But it is not cut by an axe, if it is an axe, there will be cracks on the edge of the rupture, or fractures, and the section cannot be so flat.It is not possible to cut the knife, cutting the neck with a knife is not an easy thing, you may need to cut a few knives, more than a dozen knives, that will leave a lot of knife marks on the spine.This section is quite flat, indicating that the cutting process is very careful, and there are subtle wavy streaks on the edge of the break, which is a trace of saw blade.

Cut off the head of a living person?

Lu Xiaotang hit a cold.

“It is unlikely that it is a living saw blade, the victim will struggle, and the break cannot be so neat.”Murong Yuchuan seemed to see Lu Xiaotang's thoughts.“Unless the victim loses consciousness and is in a deep coma.”
