The Zombie Apocalypse: I Came Back to Life from a Game World

In a post-apocalyptic world, Chu Nan is killed by his companions, only to revive inside the world of the game Red Dead Redemption 2. He can travel back and forth between the zombie apocalypse and the game world. By hunting zombies and using their brain cores, he can upgrade the System and increase the time he can spend in the game. While others fight over every scrap of supplies, he can feed his people by casually hunting in the game world.
