As a BOSS, I Just Want to Grow Mushrooms

The game overlaps with reality. Ye Xuan changes his profession to an ordinary mage, but gains a hidden identity - the dungeon BOSS! I just wanted to grow mushrooms quietly in the dungeon, weave my own little world with mycelium, and survive by decomposing monster corpses and cultivating mutated mushrooms. Who would have thought that one day a group of desperate S-class adventurers would break into the dungeon and see the giant mushrooms he carefully cultivated. They would yell for a rare BOSS and focus their fire output! Ye Xuan watched the poisonous spores he controlled drifting away in the wind, and watched the group of adventurers bleed from their orifices instantly and turn into nutrients—— Your group destroyed the Heavenly Court Guild From there, things spiraled out of control. The mushrooms he cultivated became more and more outrageous. They could not only spray corrosive acid, release hallucinogenic mist, but even differentiate into combat-type mycelium. His mushroom garden spread from a corner of the underground city to the entire world, and the fungus carpet climbed up the ground and swallowed up one city after another.
