The development and change of this world is getting faster and faster, since the era of cold weapons, mechanized cities have become rapid little by little, and so far, human beings have been able to fight against a variety of diseases and disasters, but, even if it has developed to the present, human beings can not go back to the past, and cannot make many people who have lost their hearts can do it again, regret medicine.

There is no regret medicine in the world, this truth is understood by Doctor Yu better than anyone else, but after Qin Mu waved his hand lightly, he really saw the Lie Yang who was still in his student days, this seemed to be a wake-up, everything was not real.

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

With a whistling, Dr. Yu subconsciously tilted his head, and sure enough, the blackboard brush that often beckoned him in high school hit the fat girl with pimples behind him in the face with a "snap".

The teacher on the stage was furious, it seemed that because of Dr. Yu's dodging action, so, a louder roar mixed with the fat girl's whispered sobs echoed throughout the teaching building: "Get out of the way!" ”

Doctor Yu was kicked out inexplicably.

Standing bored in the hallway, he pinched himself—it hurt a little.

This is not a dream.

Everything is reality, he really went back to that high school years, when Lie Yang's illness was about to explode completely.

Soon, how much longer?

He doesn't remember how many times he was kicked out by the teacher, his student life was not so good, the school bully didn't belong to him at all, the building bully was almost the same, the floor bully.

When he was young, Dr. Yu, after being kicked out, always stood honestly outside the door, but unfortunately now Dr. Yu is more than thirty years old, looking at the sky for a long time, like most novels in the reborn and traversers, after recalling the lottery numbers that may still be remembered in the head to no avail, this is thinking about how to change the world, change the future.

At least, he had to change his future with Lie Yang, and what he wanted was for Lie Yang to take the white lily and tell him what I wanted, instead of turning into a bottle of useless stones, and let Qin Mu tell him that he couldn't save the stones.

Listening to the roaring teacher who made the whole building tremble, Dr. Yu shrugged his shoulders and left the door, he didn't go downstairs, he rushed out of the school gate directly, but the ghost sent him to continue to go upstairs, and the roof of the sixth floor has always been very few people go.

In order to prevent some psychologically fragile students, jumping from the sixth floor, the sixth floor of the school's five teaching buildings is basically sealed, except for this one, the lock is only hung at the door, not locked.

In the year he graduated, there was a girl who failed the college entrance examination and jumped off this building.

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

Skillfully went upstairs, it was a cloudy day at this time, standing on the top floor, looking up at the endless, dark blue dark clouds, between each cloud vaguely visible light blue sky, such a dark and oppressive sky makes people want to suffocate.

At a glance on the top floor, I knew that the building repairers had cut corners, and they didn't even bother to wipe the cement, or they had already wiped it, and let the messy materials and rubble piles get everywhere.

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

I didn't give up and rummaged through the pockets all over my body, but they were still empty, and my mouth moved unwillingly, even if I remembered that Dr. Yu was a non-smoker in high school, and my lungs were not polluted by tobacco, I could still feel an indescribable hunger and thirst.

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

The top floor is really not bad, cutting corners in the early years, resulting in the current top floor looks decadent, the wood and steel that have not been used up before are randomly piled up on the top floor, and on the fence on one side, there are inexplicable steel brackets knotted, as if huge blood vessels and meridians.

This school building is right opposite the school gate, this abrupt pile of steel bars is just to look good when looking at the school gate, the side facing the school gate is painted with golden colors, but the side facing away is like a gnawed corpse, mottled with rust everywhere.

Dr. Yu was stunned, and was taken aback by his own thoughts, in fact, since graduation, he rarely returned to his alma mater to take a look, and the mottled and rusty steel roof did not know what the road had become.

There was a small room on the top floor, and the room had no windows, only a door, and it was locked, and I don't know what the road was for.

Doctor Yu walked into the door, it was a very simple wooden door, in the past, the door was locked, but this time, it was open, Doctor Yu was stunned, and there was a thought in his mind, someone took the lead, paused, and pushed the door open.

"You're here." The sudden sound in the door made Doctor Yu jump, almost screaming like a woman, he was reborn with a slight wave of Qin Mu's hand, and he was already illusory, like a stranger to return to the previous teaching building, back to the classroom, back to the top floor, all this was like a dream.

This dream was too realistic, he didn't want to wake up, and suddenly heard such a sound in the door, he was really startled, and stammered subconsciously replied: "Come on...... Come...... ......"

The inside of the wooden door was bare, unpainted walls, and the walls showed that the houses had cut corners - not even the cement on the walls had been smoothed.

But the person in the door almost suffocated Dr. Yu without a breath, it was Lie Yang, she was wearing a high school uniform, although her back was facing away from Dr. Yu, judging from that back, Dr. Yu was 100% sure of Lie Yang in his heart.

"Poof...... the girl shrugged her shoulders and smiled, but she didn't turn around, just said, "Close the door, idiot." ”

Doctor Yu shuddered and closed the door, but at the same time, he thought in his mind, he obviously didn't remember such a thing in his memory, could it be that after being reborn, history had changed? Listening to the fierce voice of the clever smile, Dr. Yu's soul had already flown and closed the door.

Qin Mu has been pretending to be asleep since Yu Xiu came, his eyes closed but his mind was immersed in the dream of Dr. Yu who was put on another bed by Yu Xiu, he was very curious, what would this guy dream about, when he saw Lie Yang and Dr. Yu in the same room, Qin Mu hesitated, he was entangled in whether to continue watching, in case the two of them were lit by dry firewood, how embarrassing would he be with this potential light bulb?
