Cai Tingyu was stunned for a moment, listened carefully again, and found that there was indeed no sound coming out again, which couldn't help but make him wonder if he had heard it wrong just now.

However, when he looked at the mobile phone in his hand, he found that he didn't know when, the call he dialed had been hung up, so Cai Tingyu did not hesitate to dial Cai Tingwei's phone again.

In the quiet campus, at the end of the empty corridor, a mobile phone rang suddenly in the women's toilet, which still startled Cai Tingyu, although he also knew that it was his call.

"Cai Tingwei, are you inside?" Cai Tingyu shouted at the women's toilet, his voice spread far away in the deserted campus, and there was a faint echo.

No one responded, but the mobile phone ringtone continued to ring, Cai Tingyu gritted his teeth and shouted again: "If someone is talking, if there is no one, I will come in!"

While speaking, Cai Tingyu had already walked into the women's toilet, he looked in the direction where the voice came from, and soon came to the penultimate cubicle, the door of the cubicle was closed, and the ringtone of the mobile phone came from inside.

"Bang bang!" Cai Tingyu knocked on the door a few times, and then said, "Cai Tingwei, are you inside?"

The night was eerily quiet, but there was no response.

Cai Tingyu pushed the door of the compartment hard, but he couldn't push it at all, it should have been locked, so Cai Tingyu made a very obscene action, he bent down, lowered his head, and looked inside the compartment through the crack in the door below the compartment.

I didn't see the feet of the woman in Cai Tingyu's imagination, and there was nothing in the compartment!

Straightening up, Cai Tingyu couldn't help but wonder if it could be Cai Tingwei's prank? Because the ringtone of the mobile phone came from this compartment.

The more Cai Tingyu thought about it, the more he felt that it was possible, so he knocked on the compartment door with some anger, and knocked on the compartment door "bumping".

"Cai Tingwei, stop playing! It's late, if you don't go home, your parents will be worried!" Cai Tingyu's voice was a little angry.

It's a pity that there was only an ethereal ringing of a mobile phone ringing in the compartment, and as for Cai Tingwei's response, it didn't appear!

Cai Tingyu was really hot now, and he couldn't care about it, so he climbed directly to the top of the compartment and looked inside the compartment.

But what made Cai Tingyu feel incredible was that there was no one in the compartment at all, but the mobile phone ringtone was obviously coming from inside, thinking of this, Cai Tingyu suddenly had a thought in his heart, could Cai Tingwei be hiding outside the women's toilet with a group of people at this time, holding his mobile phone to secretly take pictures of his current obscene behavior?

Thinking of this, Cai Tingyu was startled, hurriedly got down from the cubicle, and then quickly ran out of the women's toilet.

There was no imagined Cai Tingwei outside, he walked down the stairs next to him one floor, and he didn't see Cai Tingwei and the others hiding at the bend of the corridor in his imagination.

Cai Tingyu returned to the door of the women's toilet, and the ringtone of Cai Tingwei's mobile phone still came from the women's toilet.

Standing at the door of the women's toilet, Cai Tingyu hesitated for a long time, but still came to the penultimate compartment again, that is, the compartment where the mobile phone ringtone came.

Gritting his teeth, Cai Tingyu climbed into the compartment from above the compartment and began to look for Cai Tingwei's mobile phone, he first looked carefully at the four corners of the compartment and didn't see any items, so he opened the drain cover again, and it was full of water, and there was nothing.

At this moment, Cai Tingyu was a little scared and couldn't find his mobile phone, but why was the mobile phone ringing? Could it be .......

Thinking of that possibility, Cai Tingyu suddenly trembled a little, and he couldn't care about looking for Cai Tingwei anymore, he hurriedly unscrewed the door lock, but found that the door lock was not locked at all, so why couldn't he open the door when he pushed it hard just now?

A chill rushed up from Cai Tingyu's backbone, and even the hand holding the door lock began to tremble, Cai Tingyu opened the compartment door in a panic, and stepped out, probably because he was too panicked, Cai Tingyu's foot was crooked, which made him fall down all of a sudden, so he didn't die A hand just pressed on the inner wall of the toilet, although the modern toilet will not be so dirty, but the school toilet has never been very clean, and he just pressed on the residual stool.

This time, Cai Tingyu was disgusted, he hurriedly ran to the sink in front of the cubicle, turned on the faucet and began to wash it vigorously.

Even though he had washed off the stool, Cai Tingyu still felt that it was not very clean, so he washed it back and forth many times before he was relieved, turned off the faucet and prepared to leave.

At this time, the incandescent light above Cai Tingyu's head suddenly began to flicker, which startled him, and he quickly looked up at the top of his head, but when he looked up, he just glanced at the big mirror in front of the washstand, but saw two old wooden doors from the mirror, and there was a lot of fog seeping out of the old wooden door.

At first, Cai Tingyu thought it was because of the lighting that dazzled him, but when he stared at the mirror carefully, he realized that this was not an illusion at all, and the dilapidated wooden door did exist!

At this time, Cai Tingyu's whole person was so frightened that he couldn't speak, because behind him was obviously the penultimate toilet cubicle, how could it be such an old wooden door.

Cai Tingyu, who was extremely frightened, finally mustered up the courage and turned to look behind him, under this look, Cai Tingyu was so frightened that he collapsed on the ground, because at this time, where was the toilet cubicle behind him, it was obviously the two dilapidated wooden doors he saw in the mirror, and at this time, there seemed to be a whole yin wind blowing out of the wooden door, blowing the dilapidated wooden door "creak, crunch", Cai Tingyu, who was sitting on the ground, could still feel that the yin wind blowing on his face hit him, making him cold to the bone!

After the initial fright, Cai Tingyu quickly reacted, and quickly got up from the ground with a bone, and prepared to run out.

But Cai Tingyu had just taken a step, but he heard a familiar ringtone of his mobile phone, coming from the dilapidated wooden door.

The flickering eerie incandescent lamp, coupled with the familiar ringtone of the mobile phone that suddenly sounded, made the environment of the entire women's toilet look so gloomy!

Cai Tingyu's footsteps paused, his hands trembled, he took out his mobile phone from his trouser pocket, and looked at the mobile phone screen, on which the word "little sister" was displayed.

At this time, Cai Tingyu's heart was about to collapse, he wanted to ignore anything and rush out of here directly, but when he thought that Cai Tingwei might be here, he pressed the answer button with a trembling hand, and then asked in a trembling voice: "Hey! Be.... Cai... Cai.... Courtyard.... Wei... Is it?"

"Brother, save me, save me, I don't want to die! I don't want to die!" Cai Tingwei's mournful voice came from the other end of the phone.

Cai Tingyu was startled by Cai Tingwei's poignant voice, and almost threw away his mobile phone, he held back his fear, and asked in a trembling voice: "Little.... Little sister, you.... Where are you?"
