The little scum was so frightened that he threw out an emoji.

I don't know where it learned it from, and there are words in its mouth:

【No taboos, no taboos, no taboos, no taboos......】

As a Tongzi, he is still afraid of ghosts......

The girl naturally couldn't hear the screams of the little scum, and the black hole still looked at Si Nan with her eyes, and explained softly:

"Recently, the yin qi in the school has become heavier and heavier, and the students and teachers in the school have been affected to a certain extent, even if I deliberately do not show up, they can still see me."

Si Nan intercepted the key point in the girl's words, and lowered her head as if she was thinking.

She was aware of the growing yin qi in the school.

But she hasn't found the source of yin qi yet.

She didn't know the specific location of the ghost eye, and the little slag didn't give any information about it.

After thinking about it for a while, Si Nan asked the girl:

"Where did all this yin qi come from?"

The girl shoved her fallen eyeballs back into her sockets, and replied obediently:

"Yin Qi is spread from the back mountain of the school, and there has always been a steady stream of Yin Qi over there recently, and many ghosts like to gather there."

Although the girl's face was already bloody and fleshy, those exposed muscles still vibrated for a while from time to time, and it could be seen that her expression was quite rich.

The little scum felt that if he faced this scene for a while, he would be about to die on the spot.

Back Mountain ......

Si Nan reviewed the memories in Ah Ghost's brain.

The school she attends has a long history, 100 years ago.

Before the school was built, the school area was a cemetery.

The back mountain used to be a mass grave, and most of them were buried with some unclaimed corpses, so there were many lonely souls and wild ghosts wandering around there, and the yin qi was relatively heavy.

The reason why the school chose to build a school here in the first place was that the students were full of vigor and yang, which could suppress the yin energy in this area.

But that's just for schools.

From time to time, those lonely ghosts in the back mountains will come to the school at night when the yin air is the heaviest, so there will still be some supernatural events here.

After understanding the situation, Si Nan took out a piece of rune paper folded into a triangle from the small cloth bag he was carrying.

She then stood up and walked to the door of the mannequin room, and put the rune paper in the dead corner of the door frame.

The girl floated to Si Nan's side curiously, stopped in a place where the sun couldn't shine, and asked in a low voice:

"What is this?"

Si Nan turned around a little sluggishly, and his voice sounded gentle and gentle:

"This talisman is placed here, and the teachers and students in the school who are affected by the yin qi will not see you again in a short time, so don't suddenly run out and be scary recently."

The girl in front of her nodded against that terrifying face.

followed Si Nan and slowly left the mannequin room.

When she was some distance away, a man stepped out of the corner of the hallway, staring silently at her departing back.

Raising his eyes and sweeping the door frame where Si Nan put the rune paper, the man didn't know what he was thinking.

The female ghost hid in a corner in fear after sensing the man's breath.

There are many peach trees planted on the back mountain, but it is autumn now, and many peach fruits are borne among the dense peach leaves on the trees.

It seems that the person in charge of the school should have invited someone to see Feng Shui, so he planted so many peach trees to ward off evil spirits.

Si Nan followed the guidance of Xiao Zha and walked into the peach forest.

The deeper she went, the more ghosts she could clearly feel around her, and the yin qi was much heavier than when she was in the school.

In the end, she stopped at the place where the yin qi of the back mountain was the heaviest.
