Li Ling is the eldest disciple of the Emperor of the Immortal Realm. He is usually a bit lazy. He is responsible for guarding the exit of a secret realm. When he was changing shifts with Gao Buhuan, the general of the Immortal Realm, the seal of the secret realm was suddenly destroyed and many monsters escaped. At first, Li Ling and Gao Buhuan fought vigorously. Later, the number of monsters became more and more powerful. The two of them were in an increasingly dangerous situation. At the critical moment, the Emperor of Heaven came and sealed the secret realm again. Li Ling was demoted to the Blue Star after being sealed and cultivated. The Emperor of Heaven has never fully recovered from his internal injuries since the ancient war. He decided to travel far away to find treasures to heal his injuries, and temporarily handed over to his second disciple Yan Mie to manage the fairy world. Yan Mie was usually jealous of the male protagonist Li Ling, and wanted to take the opportunity to kill Li Ling, so he secretly sent an immortal to Blue Star to kill Li Ling.
