"Then I'll go first." After reading the leaves, Mei picked up the schoolbag she had just put down, thinking that this time it was really a feast for her eyes, "Bye-bye." ”

He didn't put the leaves away, just put them on the table next to his bed, not caring if anyone would come in, after all, no outsiders had come in since his parents died, except for May.

The artificial sun is gradually setting, and everything here is so similar to the earth that it once was, except for most of the people who have never seen animals and plants, everyone else seems to have no regrets in this life.

At eight o'clock in the evening, the artificial sun had completely set, waiting for the next day to rise, day after day, year after year, and almost all of the most energy-efficient light bulbs were used in the whole of the Farr, and because of the energy problem, the door to door was already going to bed at this point in time.

At that time, it was not that there were no mobile phones, the price of mobile phones was too expensive, and very few people could afford them, and few people had ever seen them, just like the scene in 2000 AD: the lights of every house emitted a faint light; Those who have a mobile phone will fiddle with the mobile phone, and if they don't, they will obediently go to bed, here at that time the earth was only short of green water, green mountains, blue sky and white clouds.

At this time, Xiao was lying on the bed, fantasizing about what the surface of the earth would look like; Will there be birds flying everywhere? Will there be a stream flowing around? But all this is just imagination.

At three o'clock in the morning, before the artificial sun rises, the whole city is in darkness, and few people still set up stalls. These people spend almost all day setting up stalls, their daily routines are very irregular and they look a little haggard, they just want to support their families, even if there are only husband and wife in the family.

"Bang!" The sound of kicking on the door woke Xiao from his dream, and suddenly a group of people in black uniforms entered, led by a middle-aged man who seemed to be young and strong in a white shirt, and he was particularly conspicuous in the darkness.

"Who are you?!" Xiao quickly got dressed and suddenly broke into his house, making Xiao unable to tell whether he was an enemy or a friend in front of him, or maybe his father's friend was looking for something now.

"Xiao, naturalized in 782 in the red school, a high school student from a poor family, often go out to work on weekends to make money, sitting in Room 301, Seat 21..." Are you trying to arrest me?! ”

The man in the black uniform turned on the only lamp in Xiao's house and put it in front of his eyes, and the faint light made him see the middle-aged man's face clearly; Wearing a new pair of square-rimmed glasses, his right eye has an irregularly shaped scar on half of his face, and that eye is also closed, as if it has been scratched by some beast.

"Don't be afraid, did you bring the textbook back without permission?" The middle-aged man closed the information and looked at Shaw, but looking at his face made Shaw very uncomfortable.

"Hmm..."Originally, all the books in the school belonged to the school, and when one generation used them up, they would be used up by the next generation, and it was not allowed to take away any resources in the school without permission, and there were few trees, so they could not blindly print and manufacture books.

"Chief Xingluo." The man in the black uniform next to him saw the pale yellow leaves on the table, "What is this?" ”

Xiao suddenly had an impression when he heard this familiar name, it seemed to be the hero of three years ago - Xingluo, when his photo and name were displayed in the newspapers and on some screens, but what he did was unknown to everyone.

"This is..."Xingluo saw this leaf and thought it was a plastic product used to deceive children, but in such an environment of lack of resources, how could anyone make such a toy.

"Leaves?!"

"This is what I picked up!" Xiao was right, after all, he didn't steal it, so there was nothing to be afraid of.

But the reality is that Xingluo took the leaf and stared at it for a long time, and then waved his hand to signal Xiao to take it away, and Xingluo didn't forget to find the book from his backpack when he left, and he was going to return it to the school.

"What are you going to do! Let me go! Xiao struggled desperately, but he was only seventeen years old, how could he go against these adult soldiers.

"You have stolen a book and you are breaking the law, and you should be detained!" Xiao was silent instantly, just went to prison for a few days, maybe the prison was still in charge, so he stopped struggling, but before leaving, he strongly asked Mei to leave a message, if he suddenly disappeared, she would definitely be sad......

Half past five in the morning.

"Lazy worm! Hurry up and get out to school! Mei shouted many times in front of Xiao's house but no one responded, she couldn't help but walk up and push them, only to find that the door was suddenly pushed open. Didn't close last night? ”

She seemed to think of something and rushed directly to the bedroom only to find that there was nothing on the bed except the messy quilt, and inadvertently turned around to find that the lamp was still hanging by the wall, and there was a line of words engraved on the wall: "I went to work, don't think about me." ”

"Stupid! Tell me if you're short of money! Mei couldn't accept the sudden disappearance, her world was only him every day, but now he is gone, her face has already slipped down two tear stains, and the snot can't help but flow out, but she still held back her crying, wiped her tears and snot with her hands and walked out to school.

"Xiaomei, where is Xiao? Why don't you see him today? Luo Hui didn't seem to be used to life without Xiao, and he still didn't forget to make the two green onion cakes that Xiao came to buy every day. He stopped Mei when he saw that she was running to school alone, he put down the work in his hand and handed Mei the two green onion cakes that had already been made to Mei, and did not take her money, at this time Uncle Luo knew that Xiao went to work...

"Hey, this kid... Why is it so worrying? The corners of Uncle Luo's eyes seemed to flicker, but he didn't have time to wipe them and get back to work.

"Please make a bold guess about what the Earth would be like now if there were no humans on Earth." The classroom without Xiao seems to have lost some of its color, and the world, which used to be as gray as a factory, has now deepened in color.

"If there had been no human beings, then nature would still be nature, there would have been no wars, no races; Nuclear weapon; Deforestation; overkilling; littering; Sewage discharge... None of this will happen! ”

"Very good, what Mei said makes a lot of sense."

Then, the teacher transferred a video to the students, because in a large place like a school, there are only things like color TV projectors, and if every household has it, it is a waste of resources.

Shown above is the year 2010 A.D., looking down on the Earth from outer space; That blue planet is really lovely.

"You see, this is the beautiful appearance of the earth at that time, due to the unscrupulous destruction of nature by our human beings, we ended up living in the underground underground city called Far."

"Remember the history! If one day the earth returns to its original state, then we must not be like our ancestors! ”
