In the shadow of the bustling city, there is a mysterious space called "Phantom Realm". It is only a thin line away from the real world, but has completely different laws and creatures. Lin Ye, an ancient book restorer, accidentally broke into the edge of the fantasy world because of a broken "Domain Boundary Map", and his peaceful life was completely broken. Weird mist, talking spiritual beings, "realm walkers" with special abilities, and secrets hidden deep in the fantasy realm are all waiting for him. Lin Ye must struggle to survive between reality and fantasy, uncover the truth of the "Realm Boundary Map", and face crises from both worlds at the same time. This is an adventure about courage, exploration and self-redemption, as well as a profound exploration of the nature of human nature and the world.
