I'm a Designer, Creating Monster Players in the Apocalypse

[Apocalypse + Game + Classes + Ensemble Cast + Invincible + Factions + Conquest + Races] [Zombies] + [Hunter x Hunter] = [Flesh Hunter]; [Plague] + [Doctor] = [Plague Demon Doctor]; The Infinite Paradise, an apocalypse game, descends, and all of humanity becomes a group of new players in the game. The entire world is randomly split into isolated paradises, but these paradises are not truly paradises. Alongside all kinds of apocalyptic disasters taking turns descending upon the paradises, world-ending calamities, crazed monsters, and twisted beings appear one after another. Humanity can only survive in the Infinite Paradise by fusing with a player's spark and becoming a professional player in the Infinite Paradise. Xu Xiu transmigrates into this world and, through an inexplicable stroke of luck, obtains the unique class [Designer]. He gains the god-level authority [Design], which lets him strip extraordinary traits from anything in the world and use them as design materials. He can not only tailor-make [Passives], [Talents], and [Skills] for himself, but also brew extraordinary potions, forge transcendent weapons, and craft magical items. He can even design and create player classes... Strip away [Zombie Traits], fuse them with a [Hunter x Hunter Spark], and design and create the [Flesh Hunter]; strip away [Plague Traits], fuse them with a [Doctor Spark], and design and create the [Plague Demon Doctor]; Years later, Xu Xiu is surrounded by a band of monstrous players who make calamities wary, monsters afraid, and twisted beings tremble. The Infinite Paradise is making gods, while Xu Duxiu is creating monsters within the paradise. A god? Xu Duxiu raises an eyebrow. Let me think about how to design the [Godslayer] class...
