"This is also an idea. Could it be that the ax can't cut anymore and the cutting machine has been replaced?" Wang Lan walked over and took a look. Sure enough, he saw the iconic wedge-shaped cut of the ax and his eyes lit up. This situation often means that this is the case.

A corpse connects the past and the future.

Jiang Yuan shook his head and said: "The use of the cutting machine is not much different from the other corpses. As for the axe, I am also relatively skilled in using it. There is no learning curve."

This is actually the tool mark part of the trace inspection. Jiang Yuan doesn't know much about it, so he can only give a rough idea.

What is more attractive is actually the issue of proficiency.

If there is no learning curve, it means that the murderer is either an insider or he has practiced with corpses before.

But this kind of conjecture cannot be said randomly. Anyway, the reservoir is still being searched, so let’s wait for the results.

Wang Lan also understood the meaning and frowned: "This person's tools are quite complete."

"There needs to be a big venue." Jiang Yuandao.

After all, these things are still far away from identifying the murderer. There are many small factories in Qinghe City, such as the industrial parks planned in the early years. None of the large high-tech factories wanted by the government came. In the end, they were still

Rented to a small local processing factory.

In addition, towns and rural areas also have various small workshops of their own, such as oil pressing mills, honey filling factories, etc. They died 20 years ago and have been resurrected in the past few years.

It looks like he's still going to die, but that doesn't stop someone from trying to die inside.

"Something more specific." Jiang Yuan brought the topic back.

"You said." Wang Lan nodded.

Jiang Yuan said one by one:

"No. 1 had teeth done, porcelain teeth, you can look for it from this aspect."

"No. 2's right humerus is fractured. This will definitely need to be taken to the hospital for treatment."

"No. 3, judging from his lumbar spine and leg bones, may be engaged in heavy physical labor."

"Number 4. Wears high heels all year round and has had teeth straightened."

Jiang Yuan tried his best to give each corpse a direction of investigation.
