What would you do if a plane crashed into a skyscraper? Scream and cry? Call for help? Hao Lanren, a top martial artist, laughs and says, "No! As a man who stands tall between heaven and earth, of course I'd punch the plane!" After his death, he transmigrates to a post-apocalyptic world overrun by zombies and awakens a system. Killing zombies earns him gold, which he uses to buy equipment and rescue the heroine. Fighting monsters and leveling up along the way, he embarks on a journey to save the world.
