"Bell bell bell ......"

The bell rang and the noise in the classroom faded away.

Dozens of students sat honestly, their hands folded on the table, and they sat with their faces looking ahead, like rows of clay sculptures. For adolescent children who are active and active, such a state contrary to nature will certainly not be their voluntary choice, but there is no way, this is Jiang Jianxue's class for Jiang Laowei, unless it is clear that he wants to fail the course, no one dares to be presumptuous.

Jiang Jianxue is a eccentric, irascib, and inhuman old man, which is the voice of all the students in the college district.

As the bell disappeared, the door on the left side of the classroom opened, and a thin old man less than 1.7 meters tall, with an electronic lesson plan under his arm, and a thermos cup in his hand, walked in. His face was full of impatience, and the dozens of students in his eyes were as annoying as flies that smelled fish.

No one dared to pant loudly, and it could be seen from Jiang Laowei's expression that he was in an uncomfortable mood again today.

In fact, when he was in a good mood, there were not a few days in a month.

Jiang Jianxue walked to the podium and put the electronic lesson plan on the operating table, and the display screen behind him lit up, showing the content of the first page of the electronic lesson plan, an extremely complex chemical derivation equation. Such an equation is obviously too difficult for middle school students, but he obviously doesn't care about these, what he talks about in class, how to talk about it, it all depends on his mood, and students only have to accept it. Do not understand? Sorry, that's your own problem.

"Today we talk about helium-3 isotopes, little rabbit cubs, listen carefully to me, I only talk once, I don't understand, I can't understand, go back and ask your parents, I will spot check in the next class, who can't answer, you don't have to come again, you can't understand such a simple thing, you are not qualified to listen to my class!"

Dropping this sentence, Jiang Jianxue opened the thermos cup and took a sip, ready to speak. Suddenly, out of the corner of his eye, he put the thermos cup down and raised his hand to a corner in the back row of the classroom.

"Who allowed you to walk into my classroom? Are you qualified to sit here? Get out! ”

Everyone's eyes followed the direction of Jiang Jianxue's finger and instantly focused on it.

A boy about the same age as the students stood up, his face scorned, he was wearing a red T-shirt printed with the words "Warm Celebration of the Chinese Team Winning the 88th World Cup", the clothes were very old, and the cuffs were rolled up. Compared with the clothes on the students around them, it looks very shabby and rustic. However, there is a special heroic spirit between his eyebrows, and his figure is as tall as a pine, which makes it seem that the quality of his clothes is not so important.

Jiang Jianxue's hand did not let go, his fingers poked the young man's self-esteem like a sharp sword, and repeated coldly: "Didn't you hear? I'll tell you to get out of my classroom! You are not qualified to gain knowledge from me! ”

The boy opened his mouth, as if he wanted to say something, but in the end he still didn't say anything, nodded slightly, and a self-deprecating smile appeared on the corner of his mouth. He bowed to Jiang Jianxue, bent down to pick up the garbage bag at his feet, and walked out the back door of the classroom.

The classroom door closed, blocking out the sound in the classroom, and the boy looked back at the classroom door, and the hand holding the garbage bag hung down a little weakly, and the garbage bag was on his wrist, hanging suffocating.

There was a sound of footsteps at the other end of the corridor, and a middle-aged man walked over, saw the depressed young man, sighed, and walked over and patted him on the shoulder: "Didn't I tell you everything, you can listen to other professors' lectures casually, don't come to Professor Jiang, you don't know his temper yet...... Can't you avoid him? ”

"I see, Uncle Wang." The young man responded, and the middle-aged man knew that his mouth was wrong when he looked at him, but he didn't say anything more, so he patted him on the shoulder again, and said, "The garbage cans are almost full, you go and deal with it, there is your Aunt Sun's class in the afternoon, don't be late." I'll go back to the database and download a copy of Professor Jiang's electronic lesson plan for this class to you, you can see for yourself, if there is anything you don't understand, come back to me, and I'll tell you. ”

"Hmm." The young man replied and said, "Thank you, Uncle Wang." ”

"Go ahead."

The middle-aged man looked at the back of the young man leaving, shook his head and sighed. The boy is what he watched grow up, but there is nothing he can do about this situation. Jiang Jianxue is not only a professor in the college area, but also his teacher, and the top decision-maker of this base. He has a high rank and the highest position, and he really doesn't dare to say anything. However, he still planned to persuade him at the end of the school council in the afternoon, after all, the events of that year had nothing to do with this child, he was just a baby at the time, and even if he needed to be responsible, it would not be his turn to bear it.

——————

The teenager went to the parking lot to get the garbage truck out and began to clean up the garbage bins on campus. His expression was very calm, it was not that he was young and old, and he could not be moved by humiliation. It's that he has experienced this kind of situation too many times since he was a child, and no matter how embarrassing he is, he is immune. But fortunately, in the academy area, there are not only people like Jiang Jianxue who treat him harshly, but also people like Uncle Wang who treat him very well.

He is sixteen years old and has been in charge of cleaning up the college district since he was twelve years old. This is not child labour, but rather leniency. After all, compared to going to the excavation site for mining, it is very easy to have machine-assisted garbage removal throughout the whole process. It's just that his peers of his age, everyone is studying in school, but he has to do this kind of work, which seems a little pitiful. But he didn't complain, because he was an orphan, he was the only one here, and he had to have such a job to support himself.

This is Ceres, the largest asteroid in the solar system, located in the asteroid belt between Mars and Saturn. All the people here are not indigenous to this planet, Uncle Wang said, everyone is from the earth. The boy once looked at a picture of the Earth, and it was a very beautiful planet. He didn't understand why everyone had to leave such a beautiful planet and come to such a barren place, wasn't this their own guilt? He asked a lot of people, but no one told him about it, and when he mentioned it, it was as if he had touched some taboo, and everyone's expressions were strange, and they all kept silent.

This made the teenager feel that maybe everyone who was displaced to this place should have something to do with their parents, at least they were responsible. But he couldn't find out, because he hadn't seen his parents.

When he was a child, he grew up in Uncle Wang's house. He always thought that he was Uncle Wang's child, but Uncle Wang told him that he was not. Until he left Uncle Wang's house at the age of twelve, he still thought that he was Uncle Wang's child, but Uncle Wang didn't want to recognize him, but now he gradually accepted the fact that he was an orphan, because Uncle Wang had no reason to lie to him.

The garbage truck came out of the campus and drove along the road, and after about half an hour, it came to an entry and exit gate. The 'college area' where the teenagers live is actually a closed ecological dome, where everything is a simulated living environment on the earth. The gate is the passage connecting the ecological dome to the real environment of Ceres, and the boy's job is to transport the garbage out for disposal. He's going to check in here, then change into a protective suit, helmet, put on the oxygen system, etc., and get ready to go out.

After putting on the protective suit, checking the oxygen supply system again to make sure everything was correct, the boy returned to the garbage truck. The red light at the top of the gate flashed three times, the first gate opened, the boy drove through the gate, the first gate closed, the yellow light of the second gate flashed three times and then opened, a barren and desolate and dead scene appeared in front of the boy's eyes.

He pressed a button under the steering wheel, and the 'garbage truck' extended a 'wing' on the left and right sides, each 'wing' with two power engines about 20 cm in diameter, and as he pressed the button, the engine started and sprayed orange flames, and the 'garbage truck' flew like this.
