In 2028, the Gray Tide virus rages and human civilization collapses. The virtual online game "Desolate Land" developed by the chaebol is actually the "Noah's Ark" of human consciousness - death in the game means the death of the body in reality, and consciousness will last forever in the virtual world with no possibility of return. After discovering the truth, Gu Chen, a former senior researcher of the Apocalypse Group, took the initiative to enter the game. With the dual-professional combination of plague doctor + puppet operator, he was gentle and elegant on the surface, but sinister and sinister in planning every battle. He profited from the battles between the major guilds and the chaebols, and finally disintegrated the chaebol control from the inside, rebuilding human civilization in the dual world of games and reality.
