It is the turn of the century and humanity has ignorantly stepped into the starry space to lay themselves bare under the eyes of gods. The young man Luo Nan bears the sins of his forefathers. He walks out of a laboratory and is seen holding burning notes up high, his feet treading on the bones of gods. A myriad of living beings are formatted in writing. Universes are added and deleted in the star records.

Finding an ancient treasure was not as fortunate as one might expect. As soon as Bai Rouyun had left the grave, countless sects and hidden families set out to kill her for the sake of obtaining her treasure for themselves.
