Chaos Point System: I Summon the Supreme Sword Demon Novel

The world teeters on collapse, ravaged by countless dungeons where summoning a creature means survival—a privilege mostly reserved for nobles. An unemployed man from Earth is reincarnated as a nameless slave afflicted with mana circulation disorder, a terminal illness giving him only until age thirty. Facing certain death without a summon, he receives an unexpected opportunity: a divine challenge. Success grants him a summon beyond imagination—the Supreme Sword Demon, an ancient and extinct demon feared even by demon gods. This legendary creature possesses unparalleled swordsmanship and a devastating ability: those slain by its sword are erased from existence, forgotten by everyone. However, summoning this power marks only the beginning. The reincarnator discovers he is not alone—the world should contain only one reincarnator, yet multiple exist. Survival demands he eliminate them before they eliminate him, setting him on a path of cosmic conflict and redemption.
