Chapter 490

Liu Wei thought that there was no formalin in ancient times, but that no one could develop it.

Formalin, also known as formaldehyde, is an aqueous solution of formaldehyde.

The formation of formaldehyde comes from the oxidation of formic acid, the secretion of some dry bees or insects.

At first, the formation of formic acid is that scientists use distilled water to distill ants, so as to get this acid. After extraction, it is found that it can be used in many aspects, with the most significant function of antisepsis and disinfection.

Since then, formic acid has been used in many research, industrial, medical, indoor, and so on.

In modern times, it's not hard to find formalin. Some students in the Department of medicine can make it by themselves.

But in ancient times, first of all, no one has published this theory. Who would extract insect secretions independently, causing the production of formic acid, leading to the formation of formaldehyde, and finally dissolving formaldehyde in water to form formalin?

Liu Wei is sure that she didn't smell wrong.

Even though the taste is much lighter, Liu Wei, as a person who has been dealing with corpses for so long, will admit his mistake in any smell. The taste of formalin will never be wrong.

The frown Never let go.

Liu Wei went a little further and saw a round eyeball on the small stone beside her. Her pupils were black and white with bloodshot all around.

Human eyes again!

Liu Wei recognized at a glance!

Next thing, Liu Wei didn't let anyone else in.

Liu Wei personally investigated the scene and obtained evidence. After a while, he collected all the left eyeballs properly and finally found that the total number reached 62.

That's not to mention the burst slurry on the ground.

When the cave is checked properly, Liu Wei looks up again and stares at the top of the cave. There are more than ten lanterns hanging.

The most obvious one is the gourd lantern in the middle.

is as like as two peas.

Maybe it's the same one.

These lanterns fly very high. Liu Wei watched the lanterns for a long time, and then rose up in the air. He went up steadily. Once he fished, he fished three lanterns down.

When the hand touched the lantern's surface, Liu Wei was stunned, and subconsciously said, "leather."

Rong Leng came up and touched.

The feel on the surface of the lantern is indeed not made of paper. It looks like fine leather, a bit like the ground cow leather and a bit like fine sheepskin.

These lanterns are obviously abnormal in this cave.

Liu Wei didn't notice. First, she made a clear record of the lantern's appearance. Then, with her own scalpel, she made a slight cut.

A good lantern is just broken.

And cut a piece of skin, hold it in your hand, feel the texture and feel of the leather, Liu Wei's face, from the beginning of the calm, slowly out of control.

Seeing the change of Liu Wei's face, Rong Leng raised his eyebrows: "how?"

Liu Wei's fingers stiffened for a moment, turned his head and looked at Rong Ling: "I think..."

"Well?"

Liu Wei didn't go on. Liu Wei didn't know how to say it, because it was incredible to guess and feel.

Looking at the above one, there are many lanterns like stars. Liu Wei's neck suddenly feels cool. If it's like Liu Wei's imagination, here

Liu Wei is used to seeing people on the big stage, especially all kinds of murders.

Whether it's serial homicide, dismemberment and dismemberment, or even some abnormal cases, Liu Wei has handled them, but at least not to make Liu Wei fuss.

But now, there are sixty-two human eyes in front of Liu Wei, and a pile of special leather lanterns. Suddenly, Liu Wei is not so calm.

Because the population involved is too large.

The big ones are beyond Liu Wei's expectation.

Rong Ling stood on the side, waiting for a long time, and Liu Wei didn't go on.

Look at Liu Wei's face, but turn again and again, but a few breaths, has turned a whole circle.

Accompanied by Liu Wei quietly, when Rong Leng thought Liu Wei was thinking about something else, Liu Wei suddenly opened his mouth quietly: "inform yamen, send someone to block the whole forest, especially this cave, set up a defense line, and listed as a forbidden area."

It's rare to hear Liu Wei's serious tone. Rong Ling looks at Liu Wei for a moment, waves his hand, and quickly orders him to go on.

After a while, brother Hu came in a hurry with several people.

Liu Wei didn't say too much and said simply: "in the murder case, the initial estimate of the dead is 35 to 40 people, both men and women, and the time is uncertain."

Hu Ge and others stared at Liu Wei, one by one inexplicable.

Murder? Are they dead again? Thirty five to forty dead?

It's impossible. How could so many people die suddenly!

And the body? Dead, what about the body after the dead?

Liu Wei seemed to know what they were thinking, so she raised her head and looked deeply at the lanterns above her head.Human skin lantern. Never thought that in this world, there are people who will make lanterns out of human skin. Rong Ling has guessed at this time. His face is ugly. Although his facial expression is not as rich as Liu Wei's, it is definitely cold. Hu Ge and others waited for a long time, but didn't wait for Lord Liu to continue. When they looked at each other, they saw that Lord Liu suddenly rose from the air, waved out a whirlwind, waved down all the lanterns, then wrapped them in a cage of internal power, and pushed them to brother Hu and others. Suddenly surrounded by a group of lanterns, Hu Ge and others stepped back. "Take these back. I want one to check." With what? A lantern? Isn't that about the murder? We didn't see the body in the murder, but we had to take a bunch of lanterns back? Is this a garden party or a lantern festival? Liu Wei doesn't explain it any more. We need to talk to sun first. After all, it's too big. Once it's leaked, I'm afraid that Gu Yong's mansion will be full of panic and unrest. It was in the middle of the night that sun Qi was dug up. It was the old shell that came to report the news, but this time, sun Qi didn't wriggle. Hearing that Rong and Liu called him to put on their clothes and shoes, they kicked and trod over. As soon as he entered the Yamen hall, sun Qi saw a pile of lights out on the ground. Each of these lanterns had a beautiful style and excellent workmanship. If they were sold outside, they would cost at least five liang of silver. It was definitely different from the paper lanterns that had to be scrapped once. Sun Qi doesn't love wealth, but since he became the official Yin of Guyong mansion, he has become stingy, so at first sight, he saw a dozen expensive lanterns in front of him, and there was a tickle in the dim sum. He was embarrassed to say, "here Two adults call the servants to get up in the middle of the night, just to give gifts to them after work? But there are few people in yamen, and we can't use so many lanterns. However, since it's the intention of the two adults, sun accepted the lanterns, just to avoid waste. We hang two lanterns outside the Yamen. If there are more lanterns, we will sell them? It's better to improve the diet for the brothers after selling the money When sun Qi finished speaking, he took a big advantage. He smiled twice, but he smiled alone. Rong and Liu looked at him silently, with deep eyes.
