[Non-systematic writing, not refreshing writing, pure doomsday totalitarian style of despair. BE, don't spray if you don't like it] Introduction: There was no sound of wind, no thunder, and no sign of any natural disaster. The entire surface world was as quiet as a completely dead corpse. The former cities, forests, mountains and rivers were all covered by a layer of warm, milky-white fungus carpet. The hyphae were as fine as a weave, clinging to every inch of the earth's folds, slowly and silently devouring all remaining traces of human civilization. The world calls it - the ground network. The old name in academia is Silongmu. Humanity has long since lost its surface. All the remaining vitality is huddled in the steel cage deep underground, lingering.
