What happens when the ultimate fan becomes the ultimate threat? Corin thought he had it made when he transmigrated into his favorite game. As an NPC with inside knowledge, he was content to watch from the sidelines until the protagonist, Sihu, turned into a sadistic monster, slaughtering innocents and hoarding power. Corin stood by in terror, waiting for the inevitable bad ending, but fate had other plans. When Sihu fails the final mission and the world crumbles, Corin is granted a second chance three years in the past. This time, he is not just playing the game; he is rewriting the rules. Armed with the knowledge of the future and a cold-blooded resolve, Corin is going to hunt down the murderer, steal his destiny, and become the hero the world actually needs. This is a high-stakes, action-packed fantasy where the underdog takes matters into his own hands to prevent a total apocalypse.
