Desolate devouring art

As an Immortal Emperor in his previous life, Liu Wuxie was one of the strongest existence in the world. But in a battle over the sky devouring divine Cauldron with the other Immortal Emperors, Liu Wuxie was forced to self detonate at the end. Upon waking up, he found himself in the True Martial Continent, in the body of a wasteel with the same name. He looked down upon as the wastrel son-in-law. But using his knowledge as an Immortal Emperor, Liu Wuxie gradually rose to being the all-mighty existance he once was.
