The story takes place in modern society. On the surface, the world is prosperous and peaceful, but in the shadows, the ancient trade of tomb robbing has endured for thousands of years. The trade is divided into four major schools, each with its own secret arts and traditions. Through changing dynasties, wars, and upheaval, these traditions have been passed down intermittently. In modern times, most practitioners have blended into ordinary life, only venturing underground again when fate brings them an ancient tomb blueprint or a treasured heirloom.
Ancient tombs are scattered across the land of Huaxia, from pre-Qin cliffside coffins and Han dynasty royal mausoleums to Tang imperial tombs, Song dynasty hidden vaults, and Ming princely tombs. Each one holds the ingenious creations of the ancients and deadly traps: quicksand and falling stones, hidden arrows and poisonous fumes, mystical formations, and tomb-guarding beasts. There are also curses and secrets passed down for thousands of years, bound up with historical mysteries hidden from the world.
