Ding Dong transmigrates into a game world and, at the cost of bloody slaughter, quietly protects a world of her own for Ning Kedi. When her secret of killing is exposed, Ning Kedi’s disgust casts her into the abyss. Only when the dagger she took for Ning Kedi pierces her chest does Ning Kedi finally understand, through Ding Dong’s diary, the deep love beneath that obsessive protection. She defies heaven to cultivate immortality and break through the boundaries of the world to find her, only to discover that the System has long since laid a trap and imprisoned her in the game. In the end, Ning Kedi raises her sword against the System, determined to die with it. As the code collapses, a long-overdue song of remorse and redemption rings out.
