The past and present life of the peach blossom fairy Lu Shiqi and the Taoist priest Duan Beili. The Taoist priest Duan Beili is keen on catching monsters, so Shiqi accompanies him to catch monsters. If he can't defeat them, it doesn't matter. Shiqi goes to the divine world to shake people. Gradually, Duan Beili evolved from an ordinary Taoist priest who did not distinguish between good and evil, and became a flesh-and-blood candidate for the head of the Taoist temple. However, at this time, Shiqi's identity was revealed. Faced with the ideal of catching monsters and Shiqi's life, how would Duan Beili choose? When the two resolved their misunderstanding, they fell into the entanglement of their previous lives. Faced with the destined mission and love of registering spirits, Shi Qi finally chose to register spirits. As a low-level demon, she had poor magic power, but during this period of time, she saw clearly that the source of the chaos in the demon world was the lack of the spirit register. Driven by fate, she retrieved the artifact, restored the memory of her previous life, and finally became the new spirit registering fairy in the heaven, ending the hundreds of years of chaos in the demon world. Since then, the demon world and the human world have not interfered, and have gone their own way. Duan Beili, on the other hand, succeeded as the leader to someone else and successfully ascended after retrieving the missing immortal bones. When they meet again, how will they choose?
