a)

The sixties of the last century.

Qingshan City Medical College, on the playground, two young girls are waving their arms at a man not far away.

"Professor, come down and come and see this!!" Two young female students in white coats stood on the green playground, waving excitedly to a man in front of them.

"Yaqin, Zhi'an, it's lunch break at this time, you two can't be stable!!" A calm middle-aged man walked up quickly, holding an anatomy book under his arm, raised his wrist and looked at the watch on his wrist, and said with a slightly sullen face, "Say, what do you want me to come over, let me see?" ”

The young female student named Yaqin stuck out her tongue in embarrassment, smiled and moved her body away, only to see a black hole about half a meter in circumference appear under her feet.

In the dark and secluded deep cave, layers of steps can be faintly seen, revealing an eerie and strange cold mist from it.

The middle-aged professor squatted next to the black hole, holding the black eyeglasses on the bridge of his nose, looked at the two young girls, and exclaimed, "How did you find this black hole?" ”

Another female student named Zhi'an dragged a piece of heavy turf next to her, put it at her feet and said with a smile: "Hehe, we were going to use a piece of turf to lay the stage, but when we dug out this piece of turf, we found that there was a dark hole under it, and you just came over at this time, so we want to teach you to see what kind of hole it is!" ”

"I see, you're lucky you didn't fall." The middle-aged professor looked at his two lovely students with a smile, and then focused his gaze on the black hole in front of him again, with a worried look on his face, "However, how can there be a hole here?!" And it's on the playground, if a student accidentally falls, it's troublesome, I'll go down and see, if it's nothing, I'll fill it in. The professor gave the book to the schoolgirl named Yaqin, rolled up his cuffs, and leaned into the hole......

(b)

Late at night, nine o'clock.

Aoyama City Medical College, the first floor of the dissection room corridor.

The silvery moonlight cast through the glass of the window on the smooth floor, and two figures suddenly appeared around the corner of the hallway, carefully moving towards the door of the dissecting room in front of them.

"I said, Xiaolan, why are you so careless, why did you leave the bag containing your mobile phone in the dissection room?!" A young man in front of him looked complaining.

"I don't want to," Xiaolan pursed her mouth, looking aggrieved, "You don't know that people's memories are poor, and besides, after doing so many experiments this afternoon, it's normal to forget your bag for a while!" ”

"Haha, that's normal for you." The man joked with a tone of affection.

"Zhang Xiaofeng!! People ignore you! Xiaolan left Zhang Xiaofeng and strode forward.

"Hey, girl, don't go so fast, I heard that this dissection room is always haunted!" Zhang Xiaofeng said to Xiaolan in a low voice, and his voice echoed in the silent corridor.

As soon as she heard that there was a ghost, Xiaolan's hairs almost hardened, she had heard of the haunting here more than once, just at this time, a night breeze blew in from the windowsill, and the frightened Xiaolan hurriedly jumped behind Zhang Xiaofeng, only revealing a small head, and slapped in fear: "Xiaofeng, you are so bad, why do you want to scare people, don't you know that people are most afraid of ghosts?!" ”

"Haha, I'm just scaring you, what's the hell in this world?! It's all made up by boring people to scare you little girls. Zhang Xiaofeng smiled, walked to the iron door of the dissection room, took out the key and opened the door.

The iron door was pushed open with a squeak, and the bright moonlight will shine into the room, but it is only a piece of light in front of the door, and the rest of the part is the darkness that you can't see your fingers, because most of the dissecting rooms have no windows, probably because they are afraid that the students will see the miserable scene inside, so only one door is installed.

Xiaolan lay behind Zhang Xiaofeng, looked at the darkness inside, retracted her head again, and said tremblingly: "Xiaofeng, I'm afraid, there are so many corpses in it......"

"Hehe, what's there to be afraid of corpses, you're still a future little doctor!" Zhang Xiaofeng swiped Xiaolan's nose with his finger and then stepped forward into the black dissection room, and in less than a moment, there was a sudden crisp sound, and a dazzling light came from the door of the dissection room, and the light was turned on.

Xiaolan couldn't help but breathe a long sigh of relief, she was not so afraid of the light, and turned around to walk into the dissection room.

Suddenly, a distorted grimace appeared in front of Xiaolan.

"Ah......" Xiaolan screamed in fright and took a few steps back, covering her eyes tightly in fright, and collapsed to the ground.

"Haha, Xiaolan, it's me!" A familiar laugh suddenly reached Xiaolan's ears.

"Hmph, good you Zhang Xiaofeng knows how to scare me!!" When Xiaolan heard Zhang Xiaofeng's voice, she immediately remembered that the grimace just now was Zhang Xiaofeng's pretense, wiped the tears that were almost falling out with the back of her hand, and said angrily: "See if I will kick you later!" ”

"I'm not afraid of you kicking it, haha, Xiaolan, this is your bag!" A delicate white bag appeared in front of Xiaolan's eyes.

"Yes, that's it, Xiaofeng, you're so nice......" Xiaolan took the white bag and looked up at Zhang Xiaofeng with a sweet smile.

In an instant, that sweet smile turned into a trembling fear, she raised her slender fingers and pointed at Zhang Xiaofeng's back tremblingly, her lips wanted to shout but she couldn't shout in fear.

Zhang Xiaofeng stood at the door of the dissection room, clasped his hands on his chest, and looked at Xiaolan who was squatting on the ground trembling with a puzzled frown: "Xiaolan, what tricks are you doing, do you mean that there is a ghost behind me?!" Then he smiled, "I don't want to eat you." ”

Suddenly, Zhang Xiaofeng stopped laughing and was stunned, his eyes were staring at the floor, another shadow, he saw a shadow on the ground, and there was a shadow standing behind him!!

Suddenly, a cyan hand stretched out from Zhang Xiaofeng's back and tightly clamped him around his chest, while the other cyan hand tightly covered Xiaofeng's mouth!!

What frightened Xiaolan even more was that the person standing behind Zhang Xiaofeng only showed half of his face, while the other half was always hiding behind Zhang Xiaofeng's head, and the person dragged Zhang Xiaofeng, who was constantly struggling, into the dissection room slowly.

Suddenly, the other half of his face was revealed from the back of Zhang Xiaofeng's head, Xiaolan's pupils instantly dilated, she screamed in horror, and fled towards the exit of the corridor.

The lights in the dissection room went out silently, and the heavy iron door slowly closed as if nothing had happened, except for a white bag lying quietly in front of the door of the dissecting room.
