Please recommend a novel that tells the story of the protagonist shuttling between the zombie apocalypse and the real world, bringing technology from the apocalyptic era to the peaceful era.

I recommend a book called "I Save the World in the Doomsday Word Game." The protagonist can bring the game's props and characters into the real world, and can even shuttle between different worlds. He can also bring the technology of the doomsday era to the modern world. I hope you like this fairy's recommendation. Muah ~😗
