Betrayed. Executed. Reborn with a system that judges the wicked. Lucien Graves was a rising star of the Radiant Lotus Temple—until he was framed for stealing forbidden techniques and sentenced to death by those he once called family. Beheaded beneath the Sky Pillar Rift, his soul should’ve been erased. Instead, he was chosen. "Lucien Graves. You were condemned unjustly. Now, you shall become the executioner of the heavens." Returned to life seven days before his death, Lucien awakens the Heavenly Executioner System—a divine relic that lets him see karma, pass judgment, and execute the corrupt in exchange for power.
