The mythical beasts and alien races recorded in the Classic of Mountains and Seas have never been just legends.
For thousands of years, the wild world and the human world have coexisted in the same heaven and earth. Only because of a heaven-sealing magic formation created by the ancient gods in the name of peace between the two worlds, they have been isolated from each other and do not know each other. Under the magic circle, the two worlds grew independently, each thinking that it was the only reality.
Until someone started to quietly destroy the boundary stone pillars supporting the magic circle.
In the modern world, vision investigator Gu Huai encountered a mythical beast found in the Classic of Mountains and Seas in the early morning on the North Fourth Ring Road. It knew him, even though they had never met. After that night, the notes his father left twelve years ago, the destroyed files, and the sensory anomalies he could never explain began to point in the same direction.
In the wild world, the exiled wizard Yan Jin traced the death path of the guardian and felt the same frequency tremors and severe pain in his own blood in every crack in the magic circle. He knew that this incident was related to the family's annihilation. What he doesn't know is that the man hiding deep in the mystery comes from a world he has never heard of.
Two lines, two people, each approaching the same truth in two worlds.
They are unaware of each other's existence. Until the cracks in the magic circle were too big to ignore, pushing them into the same dangerous situation, and they were forced to stand in front of each other, with their own secrets, their own doubts, and a question that neither of them spoke out:
Is the person in front of me a fellow traveler or another mystery?
