The protagonist, Yang Jun, transmigrates into the body of a mushroom-man leader, bullied and humiliated in the lowest-level dungeons. These dungeons are frequently frequented by "players," but these players are not human; rather, they are various other creatures besides humans. These include snails, earthworms, bacteria, and even the mythical Royal Birds who subscribe to a philosophy of winning; the Dragon Lizard Gang who love to preach victory; and the brutal and bloodthirsty Demons. To survive and see the light of day again, the protagonist cultivates various mushroom soldiers and leads his people on a conquest to rise above.
