The Emperor's Immortal Son-in-law

They call him the fool, the useless son-in-law of the Azure Dragon Divine Sect. But ninety thousand years ago, he was an undying sovereign betrayed on the cusp of godhood. Now, his eternal soul has returned, trapped in the body of a boy everyone despises. His memories are a weapon, his rage a forge for unimaginable power. The family that scorns him and the traitors who stole his life will soon learn a terrifying lesson: never awaken a slumbering emperor.
