The world is developing and changing faster and faster. Since the age of cold weapons, mechanized cities have become increasingly rapid. To this day, human beings have been able to fight against a variety of diseases and disasters. However, even if they develop to the present day, human beings cannot go back to the past and cannot make medicines that can make many people who have lost their hearts do it again and regret.

There is no medicine for regret in the world. Doctor Yu understands this principle more than anyone else. However, after Qin Mu waved his hand gently, he really saw Lie Yang who was still in his student days. It seemed that he woke up and everything was not true.

At this time, Dr. Yu was not a doctor. He was just a thin boy. He was used to sitting in the last row of the classroom, dozing off in class, reading comics, and passing notes. In short, he would do everything the boys of that era did.

With a whistling sound, Doctor Yu subconsciously turned his head. Sure enough, the blackboard brush that often greeted him in high school hit the fat girl with acne-faced face behind him with a "pop".

The teacher on the stage was very angry, as if it was because of Doctor Yu's dodging action. So a louder roar mixed with the fat girl's soft sob echoed throughout the teaching building: "Get out!"

Doctor Yu was kicked out for no reason.

Standing bored in the corridor, he pinched himself - it hurt a little.

This is not a dream.

Everything is reality. He really returned to that era when Lie Yang's illness was about to break out completely.

How long will it take to be soon?

He didn't remember how many times he was kicked out by his teacher. His student days were not so beautiful. The academic master did not belong to him at all. The master was almost the same, and the overlord of the corridor.

When Dr. Yu was young, he always stood outside the door honestly after being kicked out. Unfortunately, Dr. Yu is over thirty years old and has been stunned for a long time when he looked at the sky. Like most novels, he recalled the lottery numbers that he might still remember in his mind, and then he thought about how to change the world and the future.

At least, he had to change his future and Lie Yang. What he wanted was Lie Yang with Bai Lily to tell him the days I would like, rather than turning it into a bottle of useless stones, and let Qin Mu say to him what he could not save the stones.

Listening to the roaring teacher who made the whole building tremble and roared, Dr. Yu shrugged and left the door. He did not go downstairs and rushed out of the school gate. He just continued to go upstairs by a tragic act. Few people have been going to the roof of the sixth floor.

In order to prevent some psychologically fragile students from jumping down from the sixth floor, the sixth floor of the school’s five teaching buildings were basically sealed. Only this building, the lock was just hung at the door and not locked.

The year he graduated, a girl jumped down in this building because of the college entrance examination.

But all this seemed to have not happened at this time, because when he woke up, he was in class, not in the college entrance examination.

I skillfully went upstairs. It was cloudy at this time. I stood on the top floor and looked up at the endless dark blue clouds. The light blue sky could be vaguely seen between each cloud. Such a dark and depressing sky made people want to suffocate.

At a glance, you can tell that the group of those who repaired the building cut corners. They were too lazy to even apply cement, or had already applied it, and the messy materials and gravel piles were everywhere.

Dr. Yu stood on the top floor, touching his pocket habitually, trying to take out a cigarette from his pocket, but unfortunately, there was nothing in his pocket except for the meal tickets from the high school cafeteria.

Unwillingly, he flipped his pockets all over his body, but he was still empty, his mouth moved unwillingly. Even though he remembered that Doctor Yu in high school did not smoke, his lungs, which were not polluted by tobacco, could still feel an indescribable hunger.

Doctor Yu had to walk around the top floor aimlessly. He didn't know why he climbed up, but after being kicked out of the classroom by the teacher, there was a voice in his heart clamoring to come up and take a look.

The top floor is indeed not very good. The cutting corners of the early years have led to the top floor now looking decadent. Unused wood and steel that had not been used up were randomly piled up on the top floor. On one side, there were inexplicable steel brackets knotted, like huge blood vessels and meridians.

This teaching building is facing the school gate. This pile of abrupt steel bars are just to look good when they see it from the school gate. The side facing the school gate is covered with golden colors, but the side facing away from it is like a calved corpse, with mottled rust everywhere.

Dr. Yu was stunned and was startled by his thoughts. In fact, since he graduated, he rarely went back to his alma mater to take a look. I don’t know what the mottled and rusty steel bar top floor turned out to be.

There is a small house on the top floor, and there is no window, only one door, and it is locked, so I don’t know what to do.

Doctor Yu walked into the door by chance. It was a very simple wooden door. In the past, the door was locked, but this time, it was actually open. Doctor Yu was stunned and a thought came out of his mind that someone had taken the lead. He paused and pushed open the door.

"You are here." The sudden sound inside the door was shocked by Doctor Yu, almost screaming like a woman. He was originally reborn with a light wave of his hand in Qin Mu, but he was already fantastic. He returned to the previous teaching building like a stranger, returned to the classroom, and returned to the top floor, all of this seemed like a dream.

This dream was too realistic, and he didn't want to wake up. He suddenly heard this inside the door, and was really shocked. He stuttered and replied subconsciously: "Come... Come... Come......"

The wooden door is bare and unpainted walls, which show the cutting corners of house repair - even the cement on the wall is not smoothed out.

But the person inside the door almost made Doctor Yu feel bored. It was Lie Yang. She was wearing her high school uniform. Although she was facing her back to Doctor Yu, from that back, Dr. Yu was 100% sure that she was Lie Yang.

"Puchi..." The girl shrugged and laughed, but did not turn around, just said, "Close the door, stupid."

Doctor Yu trembled and brought the door with him. At the same time, he thought in his mind that he obviously didn't remember this in his memory. Could it be that history changed after rebirth? Listening to the voice of Lie Yang with a clever smile, Doctor Yu's soul had already flew away and brought the door with him.
