In an era when human civilization spreads across the galaxy, there are still secrets hidden deep in the universe that cannot be explained by current physics. Ling Yuan, a former elite pilot whose future has been ruined, is now an interstellar relic hunter wandering the "border". He drives his dilapidated spaceship "Stargazer" to search for valuable antiquities among the remains of ancient battlefields and the ruins of unknown civilizations, just to repay huge debts.
An ordinary "scavenging" mission led him to the tomb of a never-recorded biological battleship that resembled a huge skeleton - "Leviathan". In the core of the battleship, he discovered an object that subverted the laws of cognition: a black sphere that did not reflect, absorb, or radiate any energy, and seemed to embody the concept of "absolute nothingness" in the universe.
