Infinite Stockpiling

Qi Ji and his younger sister, Qi Mo, live on a heavily irradiated planet, and both have undergone varying degrees of mutation. Qi Mo is on the verge of genetic collapse. A System approaches Qi Ji and invites him to join an infinite survival game. Clearing the game can grant him anything he wants, including a cure for genetic collapse. Qi Ji enters the game hoping to scrape by and clear it, but the bosses are so appealing that he can't help trying to fleece them for all they're worth. In the supernatural game: Other players, chased by ghosts: Help! The headless ghost is terrifying! Qi Ji, chasing the Big-Headed Ghost: Stop! Let me borrow the head you're holding! Big-Headed Ghost: ! Only an idiot would stop! In the monster invasion game: Other players: The octopus monster's SAN is off the charts! Kill one and it splits into countless more! Qi Ji: There's a good thing like that? Watch me eat it until it's endangered. In the plant mutation game... The bosses are having a miserable time. A player has shown up who's even more abnormal than they are, so they urge all bosses to steer clear of him. Headless Ghost: That guy stole my head! Octopus Monster: At least you still have that. You only lost your head, while I lost my children! After Qi Ji finally clears the game, the battered and incomplete bosses celebrate wildly: That freak Qi Ji is finally gone! Qi Ji finally cures his sister and uses the by-products he gets from the game, fleeced from the bosses, to run a specialty goods shop. Octopuses with eighteen legs, chili peppers that absorb radiation, and slime mold that produces black soil. The people of the galaxy, who have suffered on nutrient solution for far too long: ! Where did these treasures come from?! Theme: Infinite-world story.
