As an Immortal Emperor in his previous life, Liu Wuxie was one of the strongest existences 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 wastrel with the same name. He was 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 existence he once was.
