The story takes place in a world called Guixu. It was once home to a flourishing immortal cultivation civilization, but after a catastrophe known as the Divine Silence, the Heavenly Dao shattered, the immortals and gods fell, and the entire world was tainted by an indescribable force. Spiritual energy turned into sinister energy, cultivators fell into madness and became “mutants,” and mountains, rivers, and seas became “haunted domains” governed by a series of insane, contradictory rules. Here, simply staying alive is the greatest hope of all. How will the protagonist, Gu Chang'an, use his sign-in System to survive in this world of strange tales, carefully play by its rules, and forge his way toward the future, one step at a time?
