I Pick Up Trash in Another World and Bring It Back to Build Up the Post-Apocalyptic World

After people from her own base killed her in the apocalypse, Sang Chu unexpectedly boarded a strange train. When she woke up again, she had arrived in another world! The train spirit told her there was only one way to survive: work hard and make money! So, when someone asked if they could buy the scrap metal she was carrying... Sang Chu: Hesitating for even a second would be disrespectful to money! Mutated monsters are worth a lot? Sang Chu: Then I'm heading out of the city to hunt them! She hadn't awakened any powers in the apocalypse, but she'd awakened them in this other world! However, the train could forcibly send people back to the apocalypse. But that was fine. She had money now! Fruit, vegetables, clean water: buy, buy, buy! Hovercars, smart terminals, high-tech gadgets: she'd get every last one! When she returned to the apocalypse, she would build her own utopia base! The next time she boarded the train to travel, she'd have to pay double the fare? No problem. She'd found a spirit stone mine in the apocalypse. She wasn't short on cash!
