Xu Yun sat on the upper floor of the bus No. 286X, he was too tired tonight, meeting the boss's unreasonable requirements, and the female boss's unruly temper, all of which made him feel breathless, he was just an ordinary office worker, without the background of the rich second generation, his parents were down-to-earth honest people, he didn't say that he didn't have any good looks, but he was a little fatter, and the salary was not low, but he couldn't catch up with the property price. But his helplessness and unwillingness, in this brilliantly lit and busy bustling city, it is not worth mentioning at all!

Xu Yun closed his eyes, even though he heard the sound of the bus engine, the sound of the payment, and the sound of people talking, he still enjoyed a small peace in his heart, as if something touched his heart, he remembered her. Xu Yun didn't recognize the girl's appearance, but remembered that a long, long time ago, in the sunny morning, when he was still a student, he met her who was waiting at the bus stop every day, Xu Yun tasted the quiet atmosphere in his memory, all this was so beautiful, but he felt depressed.

She was always alone, with long black and smooth hair, wearing a snow-white school uniform skirt and a black tie, quietly waiting for the bus. They never spoke, but he knew her, and she knew him. Xu Yun fell asleep unconsciously, in his sleep, he was in a white fog, he saw the girl he used to be, she came over, with a smile, they talked a lot, like a good friend to talk about everything, Xu Yun saw her smiling brightly, and he was dancing to express his opinions.

"You—" The girl hooked her lips and was saying something, bang...... Xu Yun's head slammed into the back of the seat in front of him, and the sky spun around, and the sound of brakes pierced his ears. "It's a car accident!" "Is this BMW sick?" and "Can you drive!?" It's really eight lifetimes, and the bus is driving slowly!" Xu Yun is fine, but he is really unlucky today, and he can't even dream of it!

Although there was a car accident, fortunately, the driver and passengers were not injured, so everyone got off the bus and transferred to other buses to go home. Now that we've all gotten off the bus, why don't we go get something to eat! It's eight o'clock in the evening, Xu Yun is really hungry, and he has an appetite when he looks at the food court opposite, but the road on this side can't be crossed, and the lengthy railing separates the two-way road, and it seems that he can only walk through the connecting overpass between the commercial building and the plaza floor behind him.

Xu Yun took a look, probably there was a connecting bridge on the second floor, he walked to the commercial building behind him, the building looked a little dilapidated, there was a security guard inside, Xu Yun didn't care, went straight to the direction of the elevator, Xu Yun entered the elevator, there were several passengers of the elevator present, Xu Yun pressed the button on the first floor, and other passengers pressed their own floors, Xu Yun felt very strange, it was really strange! But I can't say why I feel strange, the lights on the first floor are on, and a slightly chubby sweet girl comes out first, and he is a passenger who gets out of the elevator later.

"Huh, how is it possible? It should be the second floor?!What's going on?!" Xu Yun heard Tian Niu'er's exclamation, leaned out and looked left and right, the door on the left was open, and there were some workers working in the dark environment, it seemed that this floor was still under construction! Looking to the right, there was only a fire escape door marked "emergency exit" in the depths of the corridor, and there was no overpass leading to the opposite side.

Sweet Girl looked left and right, as if she was looking for something, Xu Yun thought to herself that this Sweet Girl might be the same as me, and wanted to go to the food court opposite and looked at the wrong floor! Xu Yun didn't think much about it, and was about to press the elevator button to go up to the next floor, he found that the elevator had no button, and it was sealed! At the place where there should be a button, there was only a piece of iron, and there was no button! Is it because it was still under construction? Sweet Niu'er also found out about it, but she was not as calm as Xu Yun, and her eyes revealed a little doubt.

"Hey, buddy, I want to ask if the overpass is on the upper floor?" Xu Yunjing walked to the construction site and asked loudly to the workers who were working inside, the workers were working in the dark environment, their brains were caught by the door, right??! wouldn't they turn on the lights so late? The workers didn't pay attention to him. Xu Yun walked up to the next floor by himself, followed by a little heel, Xu Yun knew that Tian Niu'er was following him, but he didn't care.

After going up one floor, Xu Yun opened the fire door and walked to the opposite side, which was really strange! On the opposite side of the corridor was a wall, and there was nothing else, it was a dead end! Obviously, there was a place under construction on the first floor, why was the interval on the second floor different? Of course, there was no overpass, Xu Yun didn't have time to think about it deeply, he turned around and saw Tian Niu'er at the elevator, his face was a little blue, "Why is there only a button to go up......", Tian Niu'er looked at the floor display above the elevator door, and there was no light! The number was displayed from the first floor to the fourteenth floor! Tian Niu'er felt that something was wrong, "Why don't there be lights on the underground floor?" She didn't dare to take the elevator again, how did she know if she would even lose the elevator button when she went to other floors?

Xu Yun also found out that this commercial building is really strange, not to mention that the building under construction is still open, and the security guards have not stopped anyone. Xu Yun didn't plan to take the elevator again, he wanted to walk back to the ground directly from the fire door just now. "I'm sorry, can I come with you?" As soon as he walked down the stairs, a voice came from behind him, it was Sweet Girl talking, her voice was very soft, with a little timidity. Xu Yun nodded, and Tian Niu'er walked quickly to the distance next to Xu Yun and walked down together.

The escape staircase is very quiet, in addition to the sound of footsteps, there is also a faint sound of sweet girl's breathing, Xu Yun secretly cooperated with the pace of sweet girl, after walking about three floors, Xu Yun gasped, I thought I could see the health guard in the lobby, but in fact there was only one large exhaust slot, is it wrong? Tian Niu'er snorted, her eyes showed a thick uneasiness, Xu Yun smiled at Tian Niu'er, and then began to go down again, and then walked down several floors, and then came to a floor with a wind notch, no matter how calm Xu Yun thought, it was impossible to explain this situation, they only went up one floor from the elevator, and then took the stairs up one floor, but no matter how you look at it, they have already gone down to almost seven or eight floors! Thinking of this, Xu Yun's smile couldn't be hung up, and the sweet girl unconsciously leaned towards Xu Yun's side, at this moment her hand grabbed the corner of Xu Yun's clothes, and her eyes were full of pleading!

"Don't be afraid...... Keep walking. Xu Yun has never seen this situation, he is also an iron-clad man, and he will continue to go down with courage. It's like there's no end, and suddenly there is a male office worker in front of me who slowly walks up the stairs from the stairs with his head down! Sweet girl panicked, screamed, and pulled Xu Yun down with one hand, Xu Yun let her pull, looked back, and the male office worker didn't react at all, as if he didn't pay attention to the things around him, he still lowered his head and walked up.

Pulled down a few floors by Tian Niu'er, the fire door suddenly appeared, and after pushing the fire door, I saw that it was still the road, the railing, the only difference was that we were separated by several buildings from the overpass! Xu Yun's face changed slightly, the construction building, the office workers who worked at night, the derelict security guards, the incomplete elevator, and the endless stairs...... Is this a ghost hitting the wall?" "Thank you...... Saved!" I didn't have time to think about it, Tian Niu'er's grateful voice came from the side, Xu Yun looked at her, her face was flushed because of running, and there were still tears in her eyes, it was so beautiful! Xu Yun was fascinated, and it wasn't until Tian Niu'er walked away that he came back to his senses, and said that today's experience was really bizarre! And what he didn't know was ...... This is just the beginning.
