Twenty years ago, the global spiritual energy exploded and the old order collapsed.
· The East: A large number of strange beasts recorded in the "Book of Mountains and Seas" have reappeared in China. Human beings have awakened their "bloodline talent" and can make contracts with strange beasts or directly inherit the bloodline of mythical beasts. The "Shanhai Division" was established, with the Jiuding as the center of the formation, and the "Jiuzhou Barrier" was laid.
· West: The resurgence of spiritual energy tears apart the barrier between hell and the human world, and "evil demons" such as the seven deadly sins demons, fallen angels, and the descendants of evil gods pour into the human world. Organizations such as the "Holy Sword Court" and the "Black Crown Council" were established, but internal strife was serious.
· Protagonist Lu Zhenyuan: He alone guards the "Yumen Pass" at the westernmost point of China. This place is the rift zone between the mountains and seas and the alien beasts and the evil spirits of the West. Bloody battles continue every day.
