Maybe many people will ask, are there really aliens outside the earth? Are there really immortals in the sky? Are there really ghosts in the world?

The following story may make you have a different view.

In the city, there is a pair of famous sister flowers, in one of the best schools.

My sister's name is Rong Rong. Although his grades are average, he looks outstanding and has a quiet and kind personality. And my sister Xinxin, although not as good-looking as her sister, is also among the best in school, lively and active, alert and clever. The advantages of these two people are gorgeous like a dazzling brilliance in front of students. Somewhere in the classroom, a bold eye is falling on Yan Yan's face. It's Lily. Her grades are equal to Yan Yan's. Her eyes are full of jealousy. What is she jealous of?

"Elder sister, let's go to eat ice cream after school! I heard that the new ice cream shop near the school tastes good! " Sister Yan Yan's face is full of innocence. In her eyes, she is a goldfish that will never grow up, as simple as a blank sheet of paper.

"good!" Rong Rong smiled faintly at her sister.

Ding-dong Ding-dong ended, and the students poured out of the school gate like rushing seawater.

It's obviously a little dark, and it seems to rain on a cloudy day.

"Yan Yan, look at this gloomy day. Why don't we go another day? " Rong Rong looked up at the sky and said to his sister next to him.

"Well, we can only take a rain check." The joy on Yan Yan's face immediately turned into depression.

In the blink of an eye, it reached the mid-term stage. Today is Friday.

Lily takes time to review. This time, she thought, she must surpass Xinxin and make everyone sit up and take notice of her.

At night, students study quietly in the classroom. At this moment, the air is like condensation, which is suffocating.

"Oh, dear ..." Rong Rong snorted while clutching his stomach, and the pain gradually spread to his face.

The first person who found Rong Rong had a problem was Xinxin, who was sitting next to her. She whispered, "What's the matter, sister?"

Rong Rong's face turned pale: "My stomach is a little uncomfortable." Say that finish, he took out a pack of paper towels from the drawer, got up and hurried to the door of the classroom and walked away. Before Yan Yan could react, her sister's figure had disappeared before her eyes.

Time goes by, and soon, school will be over. It's been two hours, but Yan Yan didn't see Rong Rong come back, and she was a little worried. She stood alone at the door of the classroom, holding some books in her hand, just waiting. The silver light of the moon was covered by dark clouds, and the Yin Hui sprinkled on the ground was gradually replaced by darkness.

The lights in the classroom are off. Lily was the last one to walk out of the classroom. She closed the door, turned to her heart and said sarcastically, "Ah! Xinxin, why don't you go home? Where is your sister? She didn't go back by herself, did she? Fortunately, you are still standing here waiting for her, hehe ... then I'll go first, and you wait slowly! " The other man turned his back on Yan Yan and walked to the stairs. After turning around, Lily's mouth faintly tilted with a grim smile.

Yan Yan waited for nearly three hours in the dark. The more she felt uneasy, the more she wanted to go to the toilet to find Rong Rong. But she was born timid. Because there is no light in the toilet, it is usually dark at night, so she has been standing in the same place waiting for her sister, afraid to take a look in the toilet. Under all possible circumstances, Yan Yan chose to go to the toilet. She lifted her feet and walked along the corridor, like a monster whose mouth was too dark to see the end of the toilet. ...

The school is quiet at night, and all you can hear is the occasional vibrato of slugs. She walked trembling, took out her mobile phone and turned on the light to shine forward. The light of the mobile phone suddenly lit up the distance of half a meter around Yan Yan. There is a cool breeze blowing in my ear from time to time, accompanied by the smell in the toilet. She feels very close.

Suddenly! A white shadow flashed before my eyes!
