Do you think "The Classic of Mountains and Seas" is just an ancient book?
No. It is a prison. It seals the great evil that roamed the world during the ancient flood era.
Four thousand years later, the seal broke. Zhu Yan, Jiuwei, Dijiang... These strange beasts that only exist in myths are now wandering around the city with human faces.
Lin Yan, an ordinary college student majoring in history and a delivery rider, just wants to graduate safely. Until he was dragged into the seal rift by an alien beast, and was forced to take over the ancestral bronze Yu official seal and the mountain and sea fragments, and became the only Yu official in this era - responsible for hunting down escaped alien beasts and guarding the balance between the two realms.
