Dark Fantasy Sok Seonggisa

Two years have passed since Eden was trapped in a dark fantasy game set in a medieval world on the verge of extinction that boasts extreme difficulty. He strugged as an apprentice paladin and succeeded in destroying 49 demons. He is finally appointed as a Paladin and is able to proceed with the main story of the game. However, the more he plays, the more irregularities appear, and the story and relationships with the NPCs change.

Will he be able to prevent the destruction in the game and survive despite the numerous irregularities?
