Although there is only one devil's hair in the jade piece, the devil's breath can't be covered up. As long as the martial arts have reached a certain level of cultivation, they will notice something different.

It doesn't make sense. After Gou Su is killed, the person who has a black hand will not find the jade piece.

It can be inferred that the jade piece must have been preserved by Gou su. Maybe Gou Su also knows about the evil spirit.

Judging from the artificial traces of the jade piece, Li Yifan even suspected that the magic hair in the jade piece was also left by Gou su. It is estimated that there was nothing in the jade piece.

At present, all these conjectures need him to investigate and confirm one by one.

Come to the foot of the mountain, the foot of the mountain has already set up a fence, forbid students to go up the mountain.

"It's all fenced. It looks like someone must have found something."

Li Yifan looked around the lower fence and found that there seemed to be some security guards nearby.

"There are still people watching. It seems that we can't rush in rashly."

If you want to rush up, you will be found and stopped as a villain.

Previously, Zhu Zhiwei had already reminded him that we can't easily run past the back mountain. Even if we go, we have to be careful and bypass the surveillance. Otherwise, if we don't make a clear investigation of the matter, it will be a small matter and a big one.

This warning is still fresh in Li Yifan's memory.

"Ha ha, it's hard to defeat me just by some surveillance? You look down on me

The corner of Li Yifan's mouth curved, and then his body disappeared in the same place.

With his current spirit Master's strength, he can sneak into the mountain without being noticed by anyone.

Only when there is a soul master who is at least out of the body, can he be aware of his existence.

Li Yifan directly bypassed the layers of surveillance and came to the hill.

The back mountain is not high. It is a man-made mountain. However, it is only 70 or 80 meters high. There are many trees and many strange rocks. It looks rather rugged.

Li Yifan knows that this is just a means to cover up the secrets under the layers of stones. It is estimated that when Mordor University was just established, someone had discovered the secret here.

In this era, I'm afraid it will take hundreds of years.

Standing on the hill, Li Yifan opened his mind and explored around. Then he finally found a few sporadic steps in a clump of trees.

"It should have been left by Gou Su," Li Yifan went over and looked at it, then followed his steps up.

After walking for a while, he suddenly found that his steps were gone.

"So far?" Li Yifan turns his head and looks around. His steps are so far here. It's reasonable that Gou Su discovered the existence of demons here.

It's just

Li Yifan observed for a moment, but did not find any strange place, let alone the smell of demons.

"Is it wrong?"

Li Yifan frowned, then lowered his head to the ground to observe the footprints, and began to speculate in his brain.

"If Gou Su found the spirit here, or traces and breath related to the spirit, he would be very curious and continue to move forward. No matter whether he knew the spirit before, he should go up. However, the pace has come to this point, and it is about ten meters away from the highest part of the hill... "

"On the other hand, if Gou Su doesn't find anything, he should turn back the same way. But there are only upward footprints, not downward footprints. That is to say, gousu was killed here. "

"However, if someone is killed here, he will be very panicked at the moment before he dies. His body will not be able to control his retreat and his steps will be disordered. But there is no... "

"That is to say, he disappeared all of a sudden, so he didn't leave messy footprints, and there was no blood on the scene. But in that case, how could he leave that piece of jade? "

"Did he run up the mountain after he found the jade flakes in other places, or did he find the jade flakes after he ran up the mountain?"

He must find out when the jade piece arrived at Gou Su's hands, which is related to his next investigation direction.

Unfortunately, this was not found by Gou's family, and Gou Su died early. No one explained this clearly.

"Suppose that Gou Su got the jade piece before he went up the mountain. He found the magic hair in the jade piece and knew the existence of the magic spirit. So he ran here to investigate and was killed. Logically, it is true here, but it is not true that when he was killed here, the jade piece should either fall on the ground or disappear with him. Not in the remains of his room. "

Previously, gouziqi had explained that this jade piece was found from gousu's relics.

According to this conjecture, either Gou Su didn't take the jade with him when he went up the mountain, and he knew the existence of evil spirits and that he would be killed, so he left the jade in advance.

But in this case, it can not explain another point.

He left the jade piece in his dormitory and killed his people or demons. Why don't he ransack the place where he lives?You know, the magic hair in the jade piece is likely to reveal all the secrets and let everything happen.

Li Yifan didn't think that the murderer of Gou Su would leave such a big omission.

It can be inferred that this kind of conjecture is not tenable.

"Now suppose that Gou Su didn't get the jade piece before he went up the mountain. He knew about the evil spirit, found something strange, and ran to the hill to investigate. When he came here, he was suddenly killed by some force, and the whole person disappeared, so there were no messy footprints at his feet, and no footprints in the direction of walking down the mountain. But in that case, he is dead. Where did the jade piece come from? How did he bring out the jade pieces and put them in his residence? "

Li Yifan was lost in thought.

"If this conjecture is consistent with the truth, that is to say, when gou Su came to this position before, he was not dead, but just entered a mysterious space. In other words, it is the space where demons exist, and then he brings out the jade pieces from that space, or gets the hair of demons, and then escapes from the space from another direction, so the footprints here are such strange footprints. After he got out of the space, he left the jade and was killed. "

According to this set of reasoning, the place where gousu was killed was not here. It might not be on the mountain at all.

"Mysterious space..."

Li Yifan's eyes were slightly fixed, and at the same time he looked around. If he could find the special space for the existence of demons, then the second speculation would become a fact.

Judging from the available information, the possibility of the second conjecture is undoubtedly much higher than that of the first.

"Since it is a mysterious space, according to the normal logic, if you want to hide this kind of space, you can only use arrays or some props. This is not difficult for me. "
