Then Mu Shuyu and the others checked and still found nothing, Fu Yunqing looked at Duan Yi hopelessly after investigating around, "It seems that I can't find any clues here from them." ”

"Well, the symptoms of these students look like they are insane, but they are surrounded by a thick aura of evil and ghosts." Duan Yi nodded and said his analysis.

"By the way, where is the laboratory building of your school?"

Speaking of ghosts, Mu Shuyu suddenly remembered that video.

"Oh, our school's lab is right at the back of this building." The principal was curious about what she was doing in the lab when she suddenly asked, but he answered truthfully.

Mu Shuyu was silent because of this answer.

Behind this building? Is it such a coincidence?

Duan Yi was also a little surprised, "Behind this building?" Okay, let's take a look first. ”

"Okay." The principal hurriedly responded, and then instructed Teacher Lin a few words, and then took Mu Shuyu and a few people to the laboratory.

The stairs of this dormitory are relatively large, there are many steps, and each step is not very high, which is quite a bit of a hospital staircase design.

Mu Shuyu and Duan Yi glanced at each other, both full of doubts about the design of this staircase.

It stands to reason that it shouldn't be this design, this kind of design will only make the luck of the whole building contain a fierce spirit.

Although Mu Shuyu was puzzled, the steps were limited, and in a few moments, several people reached the first floor.

"Squeak...... Ga ......"

The small voice was sensitively captured by Mu Shuyu.

The sound seemed to come from a corner away from the staircase.

When the divine sense swept away, he saw a dilapidated wooden door gently moving back and forth, making a "squeak...... quack".

Mu Shuyu looked sideways at Duan Yi, and then walked towards the wooden door, Duan Yi called the principal who was talking and Fu Yunqing followed Mu Shuyu towards the wooden door.

When I got closer, I saw that the wooden door was hidden, and there seemed to be wind inside, and when the wind blew, the door would "creak...... Chirping...... quack".

"Hey! Wasn't this door locked all the time? ”

Behind Mu Shuyu came the principal's puzzled voice.

She looked towards the wooden door, the lock seemed to be in disrepair and weathered, and one of the links was disengaged, causing the door to open.

"You're saying the door is locked all the time?"

"yes, it's always locked, and I locked the door when I moved these students here."

Mu Shuyu was about to push the door and enter when she heard an anxious voice, and her subordinates paused.

She turned her head to look at the source of the voice, and the source of the voice was Teacher Yu Lin, "Headmaster, it's good that you and a few masters didn't leave." ”

Mu Shuyu looked at her and said at the right time, "Is there something wrong?" ”

Teacher Lin had beads of sweat on his forehead.

"Headmaster, those students are talking in fits and starts."

"Let's go!" Mu Shuyu forgot to push the door, and then walked up the stairs, and the others were also infected by the atmosphere, and then several people went upstairs again.
