“From my viewpoint, this so-called supreme bastard’s body will serve as a valuable asset to simplify my life.”Dane was a carefree slacker until a deadly virus turned humanity into flesh-eating monsters—his own roommate included. After being devoured, he mysteriously awakens inside a simulated LitRPG world as a hidden extra, far stronger than the protagonist.

Regret filled Valyr as he witnessed Earth before him crumble into nothingness. Although he and the others had done everything they could, their efforts were all for naught as they stood powerless to stop the inevitable, causing billions upon billions of innocent lives to perish in the cold and unwelcoming darkness of space.

The heavens answered.

Utilizing his newfound advantages, in conjunction with his knowledge of the game and its various versions from his previous life, Valyr was going to make sure that what happened before wouldn’t happen again. And all of that began…

With him picking up the Blacksmith class.
