Law Enforcement God of the Three Realms

Immortals and mortals cannot fall in love? I am a law enforcement god. Is it reasonable to open a backdoor for myself? The Emperor won't let you? Not allowed by heaven's rules? Not allowed by the Three Realms? I am the protagonist and I am the biggest! ! The Holy Mother of the Three Realms was suppressed under Mount Laoshan because she violated the laws of nature. His son Yang Xuan became the law enforcement god of the three realms with the secret support of the Emperor of Heaven. In order to meet his suppressed mother, Yang Xuan had to serve the Emperor of Heaven and kill countless demons, ghosts, gods, and Buddhas in the three realms, so that he could achieve his current status and fame. However, Yang Xuan, who is half human, awakened to his emotions as a human. The long-standing balance of the three realms was finally broken due to his emotions. He wants to break the rules of heaven and reestablish the rules of heaven so that emotions will no longer be imprisoned in the fairy world, and longevity will no longer be limited in the mortal world.
