After the nuclear warfare, massacres started to spread throughout the entire world. The order between humans completely collapses, and the strong eats while the weak gets eaten becomes the #1 rule.

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.

Now, with the power of a deity of destruction, she desires nothing more than to claim her place in history. To do that she will conquer dungeons, make alliances, destroy kingdoms, and build an empire. After all, why ruin the world when you can bend it to your will?
