Somewhere in the toxic Bone Pits, where mechanical nightmares roam, an emaciated and wounded young wolf clings to life.

An AI calling itself Schema has assimilated Earth into its System. As a consequence, everyone gained access to status screens, power-ups, and skills. This AI turned these concepts from fiction to fact. It's easy to become intoxicated with leveling up and becoming stronger. To some, it's too good to be true, like living out a dream. For Daniel, however, it's closer to a nightmare.

Those in power do not believe in the possibility of triumph against the will of the gods, and instead squander their time and effort in indulging their needs and desires as the world quickly rots away around them. Mankind’s only hope rests on the shoulders of a man they hate the most. A man who has taken every possible measure, both accepted and forbidden, to attain power. Sungchul Kim, the man who reached the pinnacle of strength, now stands alone against the Calamities. Not because he is a hero, but because of a promise.

In a blink, I found myself in an unknown land, greeted by the textbox of an unfriendly system. It wanted me to become a great hero, save the world, win the love of the people and all that crap. But this new world already had a hero. Why should I bust my ass and deal with dragons and the unknown for people I didn't know? Let him deal with that. It's his job! So instead of being tempted by the system's nonsense, I chose a simple class. Potion maker. I wasn't interested in cultivating mana and defying the heavens, courting death, none of that crap.

I never really expected to go from full-time Neet to a God, but you know how life hits, right? Well, it doesn't really matter in the end. What matters is how I got there. You know how I said this ain't that type of guide? Well, maybe it can be. Maybe you'll figure some things out along the way—who knows? Actually I do, and you probably won't, but who cares, right? So take a seat in your mother's basement ,or whatever hole you live in, and listen to the story of how I, a full-time Neet, became a God.

None of this mattered much to Derek, aside from making living a little more perilous.
