Genius Jiang Bai awakens as the universally acknowledged weakest undead summoner, mocked by the entire city as a bottom-tier useless profession. Fortunately, he binds to an automatic grind-and-summon system. His summoned skeleton, Dagu, independently hunts monsters and relentlessly trains in Bajiquan, leveling up at an insane pace. Later, he unlocks the Sword Saint Skeleton and the Holy Light God Skeleton, with his entire team gaining absurdly overpowered abilities. Jiang Bai lies back and lives off his family, collecting experience without lifting a finger. He crushes geniuses, conquers secret realms, and claims the top spot in the national exams. He even wields holy light through the undead, shocking the Church and attracting the covetous attention of Abyssal Demon Gods!
