Lu Que traveled across worlds into a fantasy realm, cultivating bitterly for half a lifetime, only to be betrayed jointly by his trusted junior sister and personal disciple, narrowly escaping death and fleeing the sect in a sorry state. Laying low for three thousand years, he bathed in blood to ascend to the peak as a Great Emperor, and just as he was about to return to his old sect to settle a blood feud, he unexpectedly ran into a mysterious woman in red on the way. From the moment he met her, his revenge plans were repeatedly disrupted and troubles came one after another, plunging the revenge-bent Great Emperor into an endless maze of frustrating tribulations.
