Fungal Apocalypse: Spore Frenzy

On April Fool's Day, a biology professor asked the host on the show: "What is the most widely distributed creature in the world?" The host responded: "It is human beings." The professor shook his head and laughed. After laughing enough, he added to the camera: "It is precisely because humans are distributed all over the world, so if I were a fungus, I would treat humans as my transmission host and spread it to all parts of the world." The people in the audience laughed, thinking it was an April Fool's joke. In 2025, the first case of O. U. Mutant fungus was diagnosed. In the first week, experts said: the situation is controllable. In the second week, the expert said: The situation does not look optimistic, but I should carefully look for countermeasures now. By the third week, experts said: Maybe we should do something, but it's already too late. By week four, there are no experts left in the world. The dead man whose brain had been taken over by mycelium stood up again. Keep spraying spores around. But what's wrong with fungi? They are just trying their best to expand. This is an apocalypse without the halo of the protagonist. No powers, no saviors, no miracles. Just groups of ordinary people. Students, caregivers, and survivors guarding the lone building. Under the oppression of the doomsday fungus, try your best to survive for one more day. Note: Hard core details, light cheats, imaginary world, no mapping of any country.
