In a global card-drawing and class-transfer world, the underdog Zhang Yuan draws the server's only hidden class, the Sword Array Master. Starting with five draws at max constellation, he unlocks dual divine-level talents. Relying on card draws to acquire divine swords and artifacts, he solos dungeons above his level and is fought over by multiple factions. Crushing powerful enemies all the way, he resists divine projections; fighting abyss forces, the cursed King's Heart in his chest hides a body-seizure crisis, and his parents have been reduced to abyss dukes. Breaking the curse within his body, ferreting out the traitor inside the God-Chosen Club, he rallies forces to resist the Demon Dragon King's invasion, rescues his parents, and charges toward the abyss throne.
