Buddha's Light in My Left Hand, a Blood Sea in My Right

Born with a chaotic body of both immortal and demonic energies, he is mistaken by the world for a pair of useless spiritual roots, an unprecedented failure in ten thousand years. His childhood sweetheart, the sect's Holy Maiden, tears their engagement token to pieces in front of everyone, all to climb into the good graces of the sect's number-one prodigy! Just as Fan Tianjin becomes a laughingstock across the sect and is about to have his cultivation crippled by the prodigy's sword, the [Primordial God-Demon Conversion System] activates!

The more grievous his injuries, the deeper his Buddhist wisdom! The more people he saves, the more terrifying his demonic arts!

[Ding! Publicly humiliated by his former fiancee: Buddhist affinity +1,000! Indestructible Diamond Body unlocked!]

[Ding! Saved a dying spirit rabbit: Demonic Heart +500! Forbidden demonic art "Three Slashes of the Avici Path" unlocked!]

Years later, when his former wife, now an empress, is reborn in a bath of blood, consumed by regret and begging to reconcile, Fan Tianjin holds a flower between the fingers of his left hand, a vast halo of Buddha-light behind his head; in his right hand he holds a blade, with mountains of corpses and seas of blood behind him.

"Do you think you're worthy?"
