When Xue Wu Takegami said these words, Shen Ethereal and Wu Yan were also equally frightened, and their faces were also bloodless.

Shi Yuan finally understood the meaning of "only one back of the head".

"Are you saying that the head of that 'man' just now is actually just a half-empty shell?"

"Yes, exactly. If I had to describe it, it would be something like ...... Half an empty coconut shell. ”

Yukino Takekami's facial features were slightly distorted, obviously feeling extremely uncomfortable because of the picture in his mind just now.

In other words, the one who sat in the rocking chair just now was actually ...... Hatred of the heavens? ”

Shen's ethereal voice trembled, and he couldn't stop sifting through the chaff.

It was also extremely difficult for her to make such a guess.

It's horrible......

There are only four words in her mind at the moment.

Of the four, Shen Ethereal fear was probably the strongest.

"Qiu Tian is angry...... Shi Yuan whispered to himself, "head, body...... Yang Xiuning, half of her body...... Map, overlapping ......"

He turned abruptly and ran back to where the rocking chair had been, crouching down to observe the marks.

The mark looked rather strange. It was neither words nor any geometric figures, but it had an indescribable sense of regularity.

He never thought of putting it together according to what Yang Xiuning said. It is a ghost, as long as it is discovered, it is impossible to put it together without escaping.

However, "putting together" is likely to be a hint, and what can be put together is not just a map. The marks on the ground may also be some "fragment". Once the other "pieces" are found, they can be put together.

In addition, will "fighting together" be to fight together the anger of the enemy? After all, Qiu Tiannu's head (most of it) was outside the window, and what he saw just now might just be an illusion, and the real Qiu Tiannu's corpse might be somewhere in this building.

The pungent smell of formalin woke Shi Yuan from his contemplation. He looked around, looking for traces of the corpse.

"Yuki-no, can you feel the abnormal fluctuations?"

"Well, yes, right in this room...... It's weird, I don't see anything. ”

Yukino Takegami still frowned, and at the same time kept looking around.

Shi Yuan had already told him that the treasure was an earring. It's normal to have something so small that you don't notice it for a while.

Of course, Yukino Takegami also has his own ideas. He felt that the first thing he found was an earring, which did not mean that the next thing he was looking for was also an earring, maybe it would be other items. However, he didn't say it, intending to sense the anomaly fluctuations with all his might before speaking.

Shi Yuan took out his mobile phone and carefully photographed the marks on the floor, before standing up and doing his best to perceive it.

His perception is no different from Yuki Takekami, he generally senses the abnormal aura of ghosts, and he actually has no perception of special items. However, he wants to try it first, and as for whether it is successful, he will wait until he tries it.

"Will it be in the walls?"

Shen ethereal guessed.

"Possibly. However, it is impossible to destroy all the walls, and even if they do, it is difficult to find. It's best to find a clear location before you get started. ”

Shi Yuan said.

"I'm sorry, I can only feel the thing in this room, but I can't sense the exact location."

Yuki Takegami said apologetically.

"It's okay, it's not your fault."

Shi Yuan said, came to the window again, and looked at the human head.

Wait, what is this human head hanging here for? If it's for us to discover, it's perfectly fine to put it on the floor of the room, right? Why hang it outside the window? Think about it, what would we have done if the head wasn't here?

Shi Yuan's brain was running fast.

The head of the angry man hung above the window, bloody and terrifying. Not only did he have distorted features and a bloodshot face, but he also had no back skull.

Shi Yuan tried not to focus on the horror of the human head, but to try to think about the impact of the human head hanging here.

Because this head is here, it ...... What will happen?

Shi Yuan's gaze gradually shifted downward, looking straight ahead.

Outside the window, it was pitch black.

Right! That's right! It was because of that human head that our eyes were drawn upward. Without it, there's no reason for us to keep looking upwards.

That said, underneath, there's something really to pay attention to.

Shi Yuan moved closer to the window and looked down.

The unexplained traces left by the rocking chair are obviously incomplete, so could the rest of it be on the ground outside? Perhaps, it is only when you look down from above that you can discover that important pattern.

However, there is no such thing on the ground. The ground was empty and there was nothing.

The exterior of the teaching building of this medical school is concrete, hard, gray, and flat.

There are no patterns.

Am I thinking wrong?

Shi Yuan felt a trace of doubt and unease.

Yukino Takegami walked over, and he could see that Shiyuan seemed to be in trouble.

"What did you find?"

He asked.

"It's nothing," Shi Yuan said, "I just thought that the head of the person was on top to draw our attention to the past, and there might be some clue below." However, I was wrong, and there is nothing below...... There was ......"

In the end, Shi Yuan stopped.

With the help of the flashlight, he saw the clue.

The clue is not in the form of a pattern, but in the form of a distance.

Yes, distance.

They are located on the second floor. From the outside, the floor on the second floor is about 3.5 meters high, and even if you add the thickness of the floor, it will not exceed 4 meters. Shi Yuan's height is one meter seven or eight, and from his point of view, the distance between him and the ground outside is about five meters six.

However, what he saw at the moment was definitely not five meters six. It is not an exaggeration to say that it is seven meters six.

Because of these terrible and dangerous tasks, Shi Yuan specially did training in visual distance measurement. In the mission, any detail is fatal, and he must give it his all.

"Hey, Xue Wu," Shi Yuan said word by word, "Don't you think this second floor is a little too high?" ”

"Indeed...... It feels like ......."

was reminded by Shi Yuan like this, and Yukino Takegami immediately realized this problem.

"What do you mean......"

He was a smart man, and he understood what Shi Yuan meant almost instantly.

"I mean, there's more to our feet than just the floor."

Shi Yuan said, slowly retracting his gaze and looking at his feet.

On the ground, the blood-red paint-covered wooden floor seemed to glow faintly under the glow of a flashlight.

Yukino Takegami tried to stomp his foot, but he didn't feel the characteristic feeling of "hollow".
