Modern boy Lin Mo accidentally traveled to a different world called "Shenyu Ruins". This world is composed of the fragments of the ancient divine war, integrating the monsters from "The Classic of Mountains and Seas", the remaining immortal forces in heaven, and the sealed monsters from "Journey to the West". Human beings can become "Walkers" after awakening their "spiritual roots" and gain power by conquering the "Ruins Realm" (similar to a dungeon). The "Heavenly Secret System" of the Shenyu Ruins was originally transformed from the jade disk of creation left by Nuwa to patch the sky, but it was corroded by the evil gods from outside the territory, causing the monsters to go wild and the heaven to collapse. The protagonist needs to uncover the truth about the system and assemble the lost heroes from Chinese mythology to prevent the evil god from resurrecting.
