When "Rule-Based Horror" invades the "Traditional Supernatural World," there are feng shui masters with grandpa's ghost attached to them, paper effigy makers with ghost wives, and coffin keepers guarding the dead.
Caught in this perilous world, Ling Ye binds himself to a System. On one side is the system of his family's secret arts; on the other are the systems of the Myriad Worlds.
As he acquires more and more things through the exchange, he wields a Doran's Blade. When he encounters something supernatural, he simply activates the Emperor's Steps, then puts points into the Ghost Eye, God-Slaying, Daoist Horror, and God of Theater systems.
