Double Wear: Your Apocalypse, My Paradise!

This is the worst of times. A meteor shower brought endless disasters, and humans fell from the top of the food chain. There are tens of billions of zombies that are gradually evolving. They mate on the roadside, reproduce as much as they want, and devour all flesh and blood. The monsters that turned on their intelligence invaded the city and trampled the former rulers under their feet. This is the best of times. Mo Bai gained the ability to travel between two worlds by chance. The power bank picked up randomly in the ruins turned out to be a solid-state battery? The eliminated wristband AI can actually play tricks on people and drive? What? You said there is a separate nuclear fusion power supply station in this old community? Abandoned speed cars everywhere, gold that no one cares about, alloys with excessive strength, special minerals that Blue Star does not have... Some years later. Netizen: Mo Bai definitely has a system father, otherwise how could he get so many black technologies? Mo Bai: What are you talking about? Everything I have is earned through hard work.
