Qin Yu didn't answer directly, but pinched the human skin with his fingertips and lifted it, turned it to his back, pointed to the top piece and said: "There is oil on the human skin, right, it is the fat after the flesh and blood inside the corpse are decomposed, it stands to reason that the flesh and blood can decay, and a considerable part of the fat will remain in the coffin, but don't you think that there is very little corpse oil in this coffin? Because it is all in the human skin, the human skin is lifelike." ”

Anyway, Su Lin's eyelids moved, and he said lightly: "This is not scientific, because human skin is a dead thing, how can it take the initiative to absorb oil and absorb it so cleanly..."

"There's more to human skin than just dead things. Qin Yu said.

Everyone was stunned, there were still living creatures?, "Are there still Gu worms?" When Xiao Tingyan arrived that night, he had seen Mr. Zhuang take care of those soul-entwining silk spiders.

Xiao Tingyun was thoughtful, and suddenly said: " I remember I once read a book, which wrote that in the Spring and Autumn Period of the Three Kingdoms, there was a large-scale corpse Gu rebellion in the land of Yanbei, the cause of which was the lifelike body of a farmer surnamed Tang for many days after his death, confusing the world, making people think that they were not dead, and his family guarded him in a few days before they were all unconscious, just like the predecessors, and then the neighbor broke into the door and asked the doctor to come forward to inspect only to say that the family had already died, and did an autopsy, unskinned the human skin, and found that the inside of the bulging corpse was actually full of gas, and the internal organs and flesh were gone, spreading throughout Yanbei at a terrifying speed..... Later, it was not easy to extinguish the Gu chaos, and some people found that the inside of the deceased's body was hollowed out, leaving only the scalp bones, especially the skin was still lifelike, and it was preserved for a long time and was not destroyed. ”

"I didn't think it before, but after listening to what Miss Qin said tonight, I felt that there were a few points that were somewhat consistent with here. Xiao Tingyun felt that this was a bit too coincidental.

Qin Yu was also surprised, but his brows furrowed, and he didn't delve into this mysterious flying Gu that was famous during the so-called Three Kingdoms, "I don't know about this, what you said may be an unexpected gain—but I mean that there are more than dead things in this person's skin, because they are not dead, and the concept cannot be qualified, do you think the air flow is dead? Are ice cubes and water dead? Are salt and water dead? But if you put them together, they will automatically produce motion deformation, two different gases, two different substances... If the bottom of the coffin and the human skin contain different substances, in terms of material properties, the kind at the bottom of the coffin will gradually absorb the inside of the human skin due to time, and then produce another material appearance.... Do you think that's a big possibility?"

It's small, but chemically normal.

But this is only speculation after all......

"My master once mentioned that there is a hidden incense in this world, which seems to be born like a spirit, and is often used in mausoleums, do you know what?"

How do we know about your tomb robbing sect?

Xiao Tingyun noticed that Qin Yu should have already had results, so his eyes were a little brighter, and he said with a smile: "I want to hear it in detail." ”

"Since ancient times, the living are afraid of the dead, the dead are also afraid of the living, the living is the tomb robber, in order to scare away the living, many emperors will let people put the hidden incense in their coffins, the hidden incense is sealed in the coffin for a hundred years and thousands of years, if the coffin is opened abruptly, the hidden incense in the coffin is transformed into air and becomes a white mist, a white mist suddenly whistling out, if the smell of decay in the coffin is entrained, it is like a ghost whistling, it is naturally very scary, and there is a sign of the corpse or the tomb owner's ghost showing up and protecting.... However, the hidden incense is very rare, and only a very small number of ancient emperors can afford to use it, and there must be a knowledgeable person to place it personally, so it is rare, of course, only a very small number of people who know how to know the real use of the hidden incense is more than this, and there is another one, which is the hidden pattern. ”

"This kind of lines, including words and graphics, can be shaped by the fragrance of the fragrance, and after time to transform into the close skin, to make it revealed, the only way to reveal it is to soak the skin with oil to enrich the skin, so that the surface of the skin is revealed..."

Qin Yu finally said the result - the secret of this coffin is, to put it bluntly, the hidden fragrance and human skin.

"And the bottom of the coffin, put the human skin in its original position.... Su Lin, can you calculate the weight of a human body based on human bones?" Xiao Tingyun seemed to have some understanding of forensic science, Su Lin nodded when he heard this, "Yes." ”

"Then then use other substances to press the human skin and reattach it to the bottom of the coffin, simulate its object weight, and then soak it in oil for a period of time.... The human skin and the coffin are indispensable to make the hidden fragrance reappear, this is the symbiosis that Miss Qin said, right?"

Xiao Tingyun smiled, Qin Yu waved his hand lightly, and smiled slightly: "Thank you to my master for not being distracted when he talked a lot." ”

In fact, where is what the master said, Old Man Zhang didn't teach her half a Mao knowledge at all, it was because of the few sect knowledge of the Arrow Gate that happened to mention this hidden fragrance, plus Qin Yu had a lot of eyes, and he was especially good at coming to things, so he involved them.

But whether it is specific or not, it depends on the cooperation between Su Lin and Xiao Tingyun.

Hopefully the result is right.

Qin Yu's fingertips rubbed and glanced at Xiao Tingyan's scorching gaze.

If it's not right, then her value in front of the Shuai Mansion will be greatly reduced....

If it's right, it doesn't seem to be a good thing.

This young marshal's eyes are so direct, is he amazed by her talent, do you want to soak her?

————————

That night, the four of them and one cat went back to Beiping, and Qin Yu was sent first, because Qin Yu's family was close, and Qin Yu was about to get off in front of the courtyard gate outside the door.

Xiao Tingyun, who was sitting in the back seat together, cared about her and asked, "You have only been cultivating for so long, are you sure you can go in by yourself?"

Qin Yu looked back at her, "Otherwise, how can you go in?"

Xiao Tingyun was stunned for a moment, then looked at this person and smiled: "Actually, it's okay, but I'm entangled in which of the three of you will hug you..."

Xiao Tingyun and the first two: "....."

Do you want to draw lots or roll dice.

But it was just a joke, Qin Yu smiled and pushed the car door, hugged Jiaojiao and turned around to say goodbye to Xiao Tingyun and the others.

Seeing that she can still hold Jiaojiao with one hand, there is nothing to worry about.

"Miss Qin's gunshot wound is serious, although her body is recovering quickly, she still needs to pay attention, don't go out and move too much recently. Xiao Tingyun commanded softly, Qin Yu heard some of the deep meaning, his eyes flashed, and he smiled: "I don't want to go out, eat and drink at home for a while." ”

After talking to Xiao Tingyun, Qin Yu also said goodbye to Xiao Tingyan who was driving, and worked hard for him to drive.

"Invite me to dinner?" Xiao Tingyan said suddenly.

Qin Yu glanced at Xiao Tingyun in the back seat of the car and smiled: "Okay, is the eldest lady here?"

Xiao Tingyan: "My sister has been busy lately, just me, what's the matter, no?"

Qin Yu smiled: "Of course." ”

Xiao Tingyun in the back seat didn't speak, and Su Lin in the passenger seat didn't speak, but just glanced at her lightly.
