In a world where mana is the lifeblood of power, being a 'Mana Rejector' is a death sentence. For centuries, the protagonist lived as an outcast, his own body treating the world's energy as a lethal toxin. Just as he reaches the brink of collapse, a cosmic anomaly occurs: he merges with the soul of Dang Gunak, the legendary Absolute Poison Demon from a distant Murim dimension. This unexpected fusion transforms his greatest weakness into an unrivaled weapon, granting him the forbidden knowledge of poisons and toxins to dominate a society obsessed with mana. Now, equipped with the lethal arts of a martial arts sovereign, he will climb the social and power hierarchy to claim his rightful place at the top. Witness his ascent from a dying failure to a pharmaceutical tycoon and deadly master.
