Out of the gate, there is a near-vacuum on the surface of Ceres. There was no atmosphere, no living things, no plants, it was pitch black. In the distance, a thin halo and three or two points of light can be faintly seen, which are the projections of the sun reflected on the horizon of Ceres, and the mine dozens of kilometers away. Humans are able to survive on Ceres, and the minerals and basic elements provided by these mines are the most basic conditions.

There are now about 30,000 people living on Ceres, and these 30,000 people are scattered in two main areas, the Academy District and the Excavation Point, and their role is exactly what the name suggests. All the ecological domes on this planet are derived from the 'Kirin Ship' that landed on this planet back then, and they are all built with the core of the cabin separated from the Kirin Ship. The academy area was formerly the command module of the Kirin, and the excavation site was formerly the mining ship on the Kirin. From birth to the present, the teenager has been living in the college district and has never been to the excavation site.

He's been working as a cleaner in the college district for four years and has never left. The college district is short on energy, and the energy used by the 'garbage truck' he drives is strictly controlled. The distance between the garbage disposal station and the college area is fifteen kilometers, and the 'garbage truck' can travel up to forty kilometers on a full charge, just enough for a round trip and a little margin. Without electricity, all the equipment on the 'garbage truck' would stop working, so even if he could see a spot of light more than a dozen kilometers away every time he came out, he would not be able to get there. However, he still had a rough idea of what it was like over there, and the college district was open to all school-age children, and children whose parents worked at the various excavation sites also came to study in the college district. This is a boarding system, and there are two days off every month, when there will be a 'garbage truck' similar to a 'garbage truck' but several times larger than a 'garbage truck' to take them back and forth. He had a decent relationship with some of them, and occasionally heard them talk about what was going on over there.

It was dark all around, and only the headlights of the 'garbage truck' illuminated a spot not far ahead. Although the road conditions are not good, but for the teenager to drive has long been familiar with the road, for four years he has to come out twice a week, where there is a crater, where there is a boulder, he is already familiar with the heart, driving with his eyes closed is no problem. Moreover, the 'garbage truck' flies at an altitude of three meters above the ground, and the pit bag will not have any effect.

The boy's job is to put all the garbage on the garbage truck into the furnace of the garbage disposal station.

This so-called garbage disposal station was a damaged power furnace on the Kirin ship back then. It is said that there was something wrong with the Kirin when it landed, which caused the power furnace to be damaged and could not be used anymore. However, there was still a lot of fuel left in the power furnace that could not be removed, so this garbage disposal station was built on the spot where the power furnace fell. Waste disposal plants can break down waste into the most basic elemental particles, which can be used as raw materials for the production of food and water, which can continue to be recycled for human use.

Seeing the door of the garbage disposal station, the young man inevitably felt a bitterness in his heart, because he remembered that the fuel in this power furnace was helium-3, and he calculated that the class should not be out of class at this time, maybe Professor Jiang is talking about the working principle of this power furnace now.

The garbage disposal station is unmanned and there is no need for this. There are only these people on this planet, and no one will have a hot head to destroy it. However, in order to resist possible meteorite collisions, a titanium alloy shield is still made on the outside of the garbage disposal station, which looks like a small house. The boy drove the car over, and the door of the house opened automatically, and he turned the front of the car and reversed the car into the small house. That's basically what he does, when the car is in, there's a mechanical arm inside the house that takes it down, dumps the garbage into the disposal furnace, and puts it back in his car, and he's got it back.

In fact, this work can be completely left to the machine. In the past, when the teenagers were not growing up, they did the same. When he grows up, considering the energy consumption of maintaining a robot, this honorable job is entrusted to him.

It takes five minutes for the robotic arm to complete its work, and the teenager is used to using this waiting time to feel the starry sky.

The prototype of the 'garbage truck' is a single landing capsule on the Kirin ship, after a simple modification, to put it bluntly, a compartment for garbage has been added, and there is no difference between the others, and it has the same functions as the landing module. No one taught him how to use the other functions of the landing module, but the boy was a genius in this area, and since he had the right to use the garbage truck, he had figured out all the functions in less than three days.

"Uncle Wang said that the earth ...... It should be in the ......" the boy muttered, skillfully manipulating, the chair lay flat, and the roof became 'transparent'. This is a holographic projection technology, in fact, the roof is still there, but the human eye sees the image outside.

It is completely futile to discern the direction in space with the naked eye, the starry sky is so vast, and it is impossible to see even a single point of light when looking for the earth on Ceres. But the boy was tired of it, and every time he had to look for it, he naturally couldn't find it, so a minute later, he honestly entered the coordinates.

The input coordinates are also not visible, because the equipment level of the landing capsule is too low. The landing module, a low-level ship, was originally designed for low-earth orbit, and at most you can see meteorites in near-orbit. But the boy still had to watch, repeating this fruitless thing every day. Although he had never met his parents, he believed that they would return one day. If they had returned, he might have spotted them sooner by looking in the direction of the Earth.

"Still no ...... today," the boy sighed.

As a result of no surprises, there were no spaceships, only meteorites. These meteorites, I don't know how many times I have seen them in the past four years, I have long been familiar with them. He even numbered them in his heart, thinking that if he could join the mining team, he would drive them down in a mining boat and build a house with the metal they smelted, and it would not be in vain to 'get along with each other day and night' for so many years.

I don't know if the meteorite heard his desire to get along day and night, and suddenly, the boy noticed that one of them seemed to move.

"Huh?" The boy rubbed his eyes and sat up, leaning closer to see better.

Not an illusion! The young man's eyes widened, and before he could react, the meteorite that had 'moved' had already dragged its orange tail and fell down, like a precision-guided missile, rushing straight over.

"I just think about it...... Don't take it seriously, help......!! ”

One last thought flashed through the boy's mind, an explosion rang out, and the entire garbage disposal station was drowned in a burst of fire!

——————

A loud air raid siren sounded, interrupting the ongoing class.

The students were hearing this voice for the first time, panicked, frightened, and confused. Jiang Jianxue paused for a moment, he hadn't heard this voice for more than ten years, and he couldn't think of why he heard this voice at such a time, suddenly a thought flashed through his mind, and then a look of ecstasy appeared on his expressionless face.

"Sit down, shut up, and no one is allowed to leave the classroom!"

Jiang Jianxue dropped a sentence, and ran out without even taking his electronic lesson plan. The students were stunned, it was the first time they had seen Professor Jiang with such a sturdy body, and what did they see just now, Professor Jiang actually lost all the electronic lesson plans and didn't take them?

They still don't know what happened, but the students can be sure that something is definitely wrong!

At the same time, not only Jiang Jianxue, but almost all the teachers in the academy area rushed out of the classroom or office, and their destination was the same place - the academy conference room, the original Kirin ship command room!
