In the near future of 2187, technology is highly developed but society is severely divided. Giant corporations control the world. Ordinary people live under the shadow of data surveillance and mechanical transformation. The story mainly takes place in the "New Penglai" aerial city cluster, a technological fortress composed of three floating cities. It is in sharp contrast to the slums on the ground. On the surface, it is a typical cyberpunk world, but in fact, it hides signs of the revival of the ancient civilization of cultivating immortals. The collision of technology and spiritual energy produces a unique energy "spiritual flow", which becomes the basis for the integration of the two systems.
