Zombie Apocalypse, I Am Resurrected from the Game World

In the apocalyptic world, Chu Nan, who was killed by his companions, was actually resurrected in the "Red Dead Redemption 2" game world. He could travel back and forth between the zombie apocalypse and the game world. By hunting zombies, he could use zombie brain cores to upgrade the system and increase his stay in the game world. Others are fighting for supplies, but he can feed his men by hunting casually in the game world.
