Su Mo, a young Feng Shui master, stepped into the ghost house in the western suburbs and uncovered the century-old secret of the soul-eating evil ghost and the Shen family's sacrifice. In order to completely eliminate the ancient evil, he formed an alliance with Lin Yue, a folklorist, and struggled to collect three Feng Shui keys despite numerous obstacles from the Guixu Society. However, the conspiracy of Lu Chengzong, the mastermind behind the scenes, is far beyond imagination, and the decisive battle in Kunlun Ruins is about to begin. Su Mo and Lin Yue, burdened with the fate of Xuan Ming's twin orders, are about to go deep into the dragon's pool and the tiger's den, in a final showdown that concerns the world, with their lives hanging by a thread.
