The story takes place in modern society. On the surface, the world is prosperous and stable, but secretly, the tomb robbing business has been circulating for thousands of years. This industry is divided into four sects, each with its own secret techniques. After dynasty changes, wars and turbulence, the inheritance has been intermittent. In modern times, most of them are hidden in the market. Only by chance, because of an ancient tomb drawing or an ancient artifact handed down from ancient times, they return to the underground netherworld.
Ancient tombs are scattered across the land of China, ranging from the hanging coffins of the Pre-Qin Dynasty, the mausoleums of princes of the Han Dynasty, the imperial mausoleums of the Tang Dynasty, to the secret treasures of the Song Dynasty and the tombs of the vassal kings of the Ming Dynasty. Each of them contains the ancients' strange skills and deadly traps: quicksand and stones, hidden arrows and poisonous fog, strange gates and shields, strange beasts guarding tombs, and curses and secrets that have been passed down for thousands of years, involving unknown historical mysteries.
