Lin Yungui was originally an ancient immortal. After suffering a catastrophe, he accidentally fell into the mortal world and woke up in a modern city. When he first arrived, he was full of confusion about the unfamiliar world, and gradually realized the sophistication of modern people. With Su Yao's help, Lin Yungui began to explore the way to survive in the city, but gradually discovered signs of spiritual recovery - cultivators were hiding in the city, and undercurrents were surging. As his immortal power gradually recovered, he sensed that a dispute between immortals and mortals led by Li Zeran was about to break out. Under the guidance of Mr. Gu, Lin Yungui began to search for order and balance in the world of cultivation in modern society. Su Yao's awakening and Han Zimo's involvement forced Lin Yungui to make a choice between emotion and belief. In the end, facing the complete integration or destruction of cultivation and the modern world, Lin Yun used his own power to resolve the conflict between the two worlds and protect the way of coexistence between the mortal world and the immortal world. The story is based on the spiritual core of the classical fairy tale, and through the delicate depiction of modern life, it shows the integration and sublimation of human hearts, morality, and beliefs.
