Cultivation Emperor Reborn: The Divine Army Chronicles

A God Emperor at the peak of cultivation dies from sheer boredom—only to be reborn in an anime universe after a cosmic explosion. All he wants is a quiet life, but when alien assassins murder his parents and kidnap his sister, the gloves come off. Armed with his cultivator system and eons of experience, he'll unleash devastating power, level up at breakneck speed, and make his enemies regret ever crossing him. Revenge has never been this explosive.
