When Ling Mo traveled back in time to Ling Yue, the third princess of the Qinglong Kingdom, the original owner had been locked in an iron cage in the backyard of the palace for twelve years. The original owner awakened the black snake phantom, a lower-grade mortal beast, at birth, and was considered a royal disgrace. His mother, Su Wan, was framed for "having an affair with someone and tarnishing the royal bloodline" and was eventually given poisoned wine to die. The original owner was imprisoned in an iron cage by the queen (the biological mother of the second princess) on the pretext of "keeping it for the little princess to relieve her boredom." The "living target" was tortured by throwing stones, and when he was about to die, Ling Mo took over his body. In the early stage, he relied on the knowledge and fighting skills of his previous life to protect himself in the iron cage, and secretly observed and learned the cultivation methods of Shenzhou Continent; after awakening the special ability of the black snake phantom (devouring the energy evolution of other spiritual beast phantoms), he gradually got rid of control and started the road of revenge; in the middle stage, he rose up in the disputes of the four countries, revealing the dark secrets of the royal families of various countries, breaking the monopoly of "the supreme beast phantom"; in the later stage, he broke through the sky-controlling realm, killed all enemies, ascended to the divine domain, and reshaped the rules of heaven in Shenzhou Continent.
