3000 Working Days Left

The earth has become uninhabitable due to the destruction of the plague. The remaining 500,000 people have migrated to the terrestrial planet Altma six light-years away from the earth. One hundred years later, the human rulers of the star sent 500 people back to the earth to carry out a project to transform the earth's environment. The protagonist, Liu Jindong, works alone in a factory to collect and analyze the earth's air. The only people he communicates with are the driver who comes to collect the compressed air tanks and the officials who come to inspect the factory. There are also limits to where he can go out. The protagonist accidentally discovered the secret of the factory. In order to cover up his own interests, a manager of the base arrested him and removed most of his brain, leaving only a small part to maintain his vital signs.
