My Villa in the Apocalypse

After five years of fighting to survive in the apocalypse, Jin Yang finally got herself a four-square-meter place to stay at the base. Three days after she moved in, the base was overrun. Reborn on the third day of the apocalypse, she walks into a large, bare villa when a phone drops from the sky: "Ding! Your Adorable System is online! The land before you can be improved without limit, freely renovated and expanded, until it becomes the strongest and most comfortable fortress in the apocalypse." A big bed, a generator, a sofa, a solar water heater, a fridge... Jin Yang looks at all the "products" on her phone and rubs her hands excitedly. This time, she's going to build a "home" of her own. One night, she finds a hidden item in the "shopping district." It's on sale for just one silver coin. "You can't go wrong at this price. Let's give it a try." With a bang, an incredibly handsome man appears on her bed. Wait, that's the discounted item she bought? Housework, cleaning, breakfast, lunch, dinner, zombies: the man takes care of it all, and Jin Yang finally gets to enjoy a carefree life in the apocalypse. For one silver coin, she got herself an all-purpose man who's capable, easy on the eyes, and good in a fight. Huh, did she get a bargain? If only he didn't keep offering her "services" at night...
