On earth, Felix is just a normal guy, a bit of a loner but otherwise normal. In the multiverse, under the rule of The System, he's a caster. Fascinated by magic and hungry to learn, grow and discover, this series follows Felix on his adventures through the integration and beyond.

The world was destroyed, the apocalypse descended, a new era began, and the right to survive as a Lord was granted to every person.Domains, Heroes, Troops, Treasures, Resources—all of the countless servers constructed by the myriad continents were opened up.Qin Muye looked at his panel, which was akin to cannon fodder, and his domain with its damaged suffix, and felt a strong urge to cry but no tears would come.No divine talent, no hidden hints, no overpowered Profession.“If that's the case, then I'll just have to adapt and live in a different way.”
