The beautiful Blue Star tragically fell victim to an invasion by enemies from the Otherworld. The globe was left riddled with wounds, but it also presented an opportunity for the Awakening of the Blue Star people—a chance to choose something other than hot weapons. Individuals could use their own strength to slay enemies, amass wealth, and reach the pinnacle of their lives.Ye Nai was lucky enough to awaken in advance, releasing energy spores that could decompose organic matter. He had planned to make a stunning debut during the mass Awakening at school, but results showed he hadn't awakened?!What the hell?I haven't awakened?Then what's this Fungal Mycelium I have that can decompose abnormal creatures?Ye Nai gave a devilish smile.Haha, everything that happens is to my advantage. Whether it's the enemy or abnormal creatures, obediently fall into my hands and become nourishment for my mycelium!

One day, I woke up only find out that I’d become a Demon Lord, an individual responsible for protecting a dungeon. The world I’d been spirited away to was one filled with violence. Gigantic monsters wandered through it and competed with each other each and every day for the right to survive. I had no choice but to strengthen my dungeon’s defenses in hopes of living another day—or at least that was what I’d thought. For some odd reason, I instead ended up spending my days in relaxation and bliss.
