The Perfect Immortal Son-In-Law

When Taixuan Immortal, the most powerful immortal in the Nantian Immortal Domain, opened his eyes, he was actually reborn in the body of a useless son-in-law with the same name. In his previous life, Zheng Shaoge tried to enter the long river of time and space in the past to retrieve his fallen master, the "Hundred Flower Immortal King", and eventually perished in the long river of time and space. I thought that I would die and disappear, but I didn't expect that a ray of soul escaped from the long river of time and space and was reborn in the body of a useless son-in-law in the secular world. In this life, there are still more than three hundred years left before the master's death, and time is extremely tight. In this secular world with thin spiritual energy, can Zheng Shaoge return to his peak before the death of his master, return to the South Heaven Immortal Realm, and prevent the tragedy from happening again? His story begins with his useless son-in-law. The name of trash was officially rewritten from the moment he opened his eyes...
