The Merciless Hero

After playing the game Guardian of Humanity for years and becoming an expert, Han Je-u finds himself dragged into a new server of the game and forced to play at the weakest level. The problem is, death in the game means death in real life too. As Demon Kings rise and imperial forces collide, even the routes he once mastered twist into unfamiliar danger. Can Je-u break free from the patterns that doomed every past run, or will a world that no longer follows its established routes prove too much of a challenge? (Source: Webtoon Entertainment)
