This Dungeon Grew Mushrooms

"A stolen wondrous soul, the power of a hero, plus a classic suffering start as a catalyst!"

"Such a savior would... Holy crap, how did a mushroom fall in?!"

Lin Jun, who inexplicably transmigrated into a mushroom, was immediately cornered by various monsters in the deep levels of the dungeon.

With no hands, no feet, no eyes, he survived purely by decomposing corpses and plundering skills as a cheat.

He even opened a mushroom garden in the dungeon, planning to gradually conquer the dungeon in reverse.

All for the day he could bask in the sun again.

Until that day, a silly duke's daughter, who had been turned into a mushroom, fell from above.

And she attracted a team of diamond-ranked adventurers coming to rescue her.

Lin Jun, who inexplicably hitched a ride upwards, discovered that this wasn't a dungeon at all; it was clearly a buffet paradise!

Unbeknownst to anyone, his fungal mycelial carpet spread throughout every corner of the dungeon. All dead flesh was his nourishment, and mushrooms even grew out of the dungeon, seeking more...

"Wait, I'm really not on a Zerg script, am I?"
