Stripped of his Chosen One status, the protagonist awakens as a mere NPC in a colossal cultivation world built from ancient mythology.

But in this realm, Chosen Ones are the protagonists with plot armor and destiny on their side—while he's just another disposable character in their story. Can an NPC defy fate and reclaim his place in the real world?
