Ruyu's reputation for "ghost sorrow" is still very loud, and the dean also has friends who know about Ruyu.

In the past few years, Ruyu has also received invitations from the dean to go to a certain place for a fee.

Ruyu did not refuse, and those who were not far away went to see it, anyway, they all made money.

Their orphanage and university are in the same city, and they both run schools in the same city, and it is not surprising that the dean and the principal know each other.

Soon, they arrived at the women's restroom on the fourth floor.

Standing outside the door, I couldn't hear the sobs at all.

Ruyu took out her mobile phone and glanced at the content of the post, and roughly determined the time: there would be crying at eleven o'clock every night.

The man who was in distress yesterday also came here at 11 o'clock.

Striding in, it was clean and tidy, without the slightest dilapidation.

On the face of it, this is not a place to hide dirt.

Zhao Xiaoxue glanced at it a few times, "It feels very ordinary, there is nothing special." ”

Ruyu thought about it and stepped back, Zhao Xiaoxue didn't know why, so she hurriedly followed, and asked curiously: "What, is there a situation?" ”

Ruyu didn't answer, and then, Zhao Xiaoxue saw her walk into the men's toilet next door.

Zhao Xiaoxue: "......"

"Ruyu, why did you come here, do you think you made a sound from here?" Zhao Xiaoxue also walked in.

The men's toilet has a different structure than the women's restroom, and it is a bit dirty in comparison.

The floors and windows were dusty and a little stinky.

But if you look closely, the wall is still very well preserved and clean.

There are no cracks on the floor, and if you can wipe it, you probably won't be able to see how dilapidated it is.

Ruyu squatted on the ground and stretched out her hand to wipe the ashes, and said thoughtfully: "Because there are many classrooms and the corridors are empty, it is easy to form echoes when speaking, which will confuse the direction of the sound." ”

"So you think the sound is coming from here?"

"No, not here."

Zhao Xiaoxue was stunned, "Huh? ”

"I'm just here to confirm one thing."

Ouyang Ruyu re-exited the men's toilet and walked into the women's toilet.

She stood in the middle and observed for a while, and then suddenly said, "Don't you think it's too clean?" ”

Zhao Xiaoxue was still at a loss, "What? ”

"This women's toilet is too clean compared to the men's toilet."

"Maybe girls prefer to be clean?"

Ouyang Ruyu shook his head and said with certainty: "No matter how much you love cleanliness, you can't be so tidy in a deserted situation." ”

There was a glint in her eyes: "This toilet has definitely been cleaned recently!" ”

Zhao Xiaoxue was very surprised, her eyes suddenly lit up: "Then check the surveillance record......

Before she could finish speaking, her voice lowered.

She forgot that this was an abandoned school building, and there was no surveillance footage at all!

Ruyu clapped her hands, slapped the ashes off her hands, and looked left and right: "Anyway, this is not a supernatural incident, but a man-made prank incident." ”

"Every night at eleven o'clock, there should be some device here that automatically emits the sound of a girl sobbing, and the toilet that has been specially cleaned can indicate that it was a premeditated plan.

But the planner does not necessarily have a malicious mood to make this plan, if it is really malicious, it is impossible to deliberately clean the toilet without adding other materials. ”

Zhao Xiaoxue looked curious: "What does it mean to add other ingredients?" ”

Ruyu turned her head to look at her: "If you want to deliberately set this up like a haunted house, every 11 o'clock will make a sound to scare people."

Would you make the toilet so clean and tidy that it looks like it's been cleaned without adding some weird things? ”

"For example...... What to add? Zhao Xiaoxue asked scared and expectant.

Ruyu's face did not change: "The corpses of dead rats, the rotting bodies of various animals, the simulated humanoid bones from the biology museum, there are many things that can scare people."

If I come to set up the scene, even if it is an adult man, I will be scared. ”

Zhao Xiaoxue silently gave her a thumbs up: "Our little sister Ruyu is as handsome and mighty as ever." ”

Ouyang Ruyu seriously checked the women's toilet again, and finally looked at the ceiling.

"Since it has been cleaned, mops and brooms should be found nearby, although this school building is deserted, it is still very close to our school building.

If someone has taken something large, such as a wooden ladder shelf or something, there should have been students who have seen it.

If you don't use a tool like a wooden ladder shelf, it will definitely be a crime committed by multiple people, at least one person must step on the shoulder of the other. ”

Zhao Xiaoxue was a little stunned when she heard this: "Wait, why do you want to step on another person's shoulder?" ”

Ruyu smiled: "Because only by stepping on the shoulders of another person can you reach the height of the ceiling." ”

"Suspended ceilings?"

The corners of Ruyu's mouth hooked slightly, moved her body, and suddenly jumped after a few runs.

With a "boom-" sound, her body ejected like a high jump.

Zhao Xiaoxue's mouth opened into an "O" shape, and she applauded slowly, "It's worthy of being a non-human jade, her physical fitness is comparable to that of an athlete, how can she be so powerful......"

At this time, Ruyu's voice with a shallow smile sounded: "I found you." ”

She landed firmly on the ground and looked up in the direction of the ceiling.

"In the suspended ceiling, which is still some distance from the ceiling, a black machine is placed in the middle mezzanine, and it is preliminarily determined that this machine will make a sound at night.

Other features, unknown. ”

Zhao Xiaoxue suddenly realized: "It turned out to be put on the head, no wonder I can't find it no matter how I look for it!" ”

"Because of the echo of the empty space, coupled with the nervousness of people.

Even if you feel the sound coming from the top of your head, when you look at it, you will feel that the sound is coming from somewhere else. ”

Ruyu speculated, walked to the window and looked.

It's also a coincidence, the person stands here and looks up, and if the ceiling is hidden, it is right under the machine.

Zhao Xiaoxue hurriedly ran over and asked, "Ruyu, are we going to take down this machine?" ”

"What to take, we are here to judge if this is just a supernatural incident, you really think you are Sherlock Holmes trying to arrest someone?"

Zhao Xiaoxue blinked, a little confused: "If you don't say it, I almost forgot." ”

She turned to say with great interest: "Your posture just now is so cool, how did you do it by jumping so high, teach me!" ”

"This is a miracle that took fifty years of life, so I ask you if you still want to learn it." Ruyu said with an honest face.

Zhao Xiaoxue bumped her arm, "Who are you fooling, how can you, the person who is most afraid of death, be willing to exchange fifty years of life for this?"

Tell me, how do you do it? ”

Ruyu casually ripped out a training method: "Squatting on the horse, training waist strength, insisting on half an hour every day, you can do it after a year." ”

Zhao Xiaoxue looked at her suspiciously, "Really? ”

Ouyang Ruyu's expression was solemn: "Pearls are not so real." ”
