The End of the World: Atlas Is Coming and I Am Sailing Alone

Comet Atlas. At first people thought it was just an ordinary celestial body. Titan worms, pheromone invasion, radiation, massacre... Until the planet collapses. With the help of the system, Lin Chen manufactured a life support system and built an interstellar spacecraft. I thought that as the protagonist, I could change everything and save Blue Star. But in the end, one can only start one's interstellar voyage before the world is destroyed.
