Class Change: Necromancer, My Skeletons Evolve Without Limit

In an apocalypse where gods unleash a System to harvest souls, I awaken as the SSS-rank Lord of the End. While others summon frail skeletons, my bone gunners sweep through the exam grounds with Gatling guns in hand. When conglomerates covet the Seeds of the Abyss, a Necromancer Sword Saint rises from beneath the undead sky screen. From my mecha bone legion trampling the battlefield in the Abyss to my ghost carrier smashing through Tokyo Bay's defenses, the gods discover that the undead are a loophole in the System. By then, I'm already holding a black-hole scythe to the Goddess of Fate's throat: "It's time the undead rewrote your rules."

The Undead Ancient Domain holds the truth behind 99 world resets, while the Underworld Library conceals the key to the gods' trap. With my chess-playing skeleton daughter and fallen Holy Light Bone Dragon, I turn Mars's silicon-based civilization into undead and clash with higher-dimensional singers, meeting their dimensional attacks head-on. When a million people willingly become undead to break free of fate, the System's source code finally reveals its ultimate choice:

Become a new god and rule the age, or forge the sun into a Nether Sun and reshape the eternal cycle into one without reapers?
