A hundred thousand years ago, there was a great war between cultivators. Immortals fell by the tens of thousands, the path of cultivation itself was severed, and after the dust settled, tombs forested the world.

A hundred thousand years after the last legend faded, Lu Yun, commandant of tomb raiders, descends upon the world. Armed with the Book of Life and Death, he has some burning questions to answer.
