The World Is a Game

Wu Bufeng discovers that the world he transmigrated into is a game's database, with an AI brain that can extract parts of it at any time and evolve them into dungeons. He is the only player in the real world, traveling between dungeons and reality. Unlike other players, this lets Wu Bufeng modify the dungeons in advance:

"This isn't a bank robbery. Where did you get that big truck?"

"It's supposed to be a food-delivery race. How did the stationmaster come in first?"

"Isn't this a supernatural dungeon? Where did he find an entire arsenal? What do you mean, ballistics is a kind of Dao?"

Watching the players' furious complaints on the forum, Wu Bufeng scoffs and opens the pinned announcement for a major DLC update. He wonders what he should stock up on to get through the zombie apocalypse.
