- Description from Novelupdates

“World” is a game renowned for its remarkable freedom.

In “version 3.0”, I made the decision to maximize my focus on boosting magical abilities!

All stats now revolve around magic! But In turn, I embraced a substantial number of disadvantageous traits.

However, that is inconsequential. I am determined to forge the ultimate Wizard character, It matters little whether the character’s outward appearance resembles a walking corpse.

Yet… What is this?

I have suddenly transformed into that very character – a character with prodigious talent, yet unable to survive a single day without relying on drugs.

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.
