Transmigrated into a white python, Xu Jinglong awakens the feeding rebate system, and accidentally encounters the reincarnated and rebuilt dragon clan female empress Murong Wange. He continuously feeds monster cores and spiritual materials, relying on a hundredfold rebate to rapidly evolve and transform into a cloud-dome flood dragon. Man and snake accompany each other to venture through the Ten-Thousand Monster Mountain Range, fiercely fighting the golden toad and black-iron turtle, rushing to the trial secret realm, sweeping across human and monster clan proud prodigies, competing for the millennium spiritual fruit, all the way crushing strong enemies, and stirring up monstrous wind and clouds within the secret realm.
