Connecting to the Interstellar at the Start, I Exchange Scrap for Billions

The fake young lady, Wen Zhi, was driven out of the Wen family. Penniless, she returned to her gambler father's home, burdened with millions in debt, and three younger siblings waiting to be supported. Faced with a catastrophic start, she awakened a small shop connected to a future interstellar world as she stepped into her family's old recycling plant. The items she was supposed to sell? Scrap metal, or simply 'junk'!

Even more absurdly, the first time the shop appeared, it was on an insectoid battlefield. Wen Zhi's eyes rolled back; she thought, "Who in their right mind would come to this godforsaken place to buy three rusty screws?!" The next second, a handsome male beastman with golden vertical pupils burst into her small shop. "Can I exchange these three A-grade energy items for this one stone?" Wen Zhi looked at the perfectly pure, egg-sized diamond in her hand, beaming with joy, and nodded frantically, "Yes, yes, yes!" Returning to the real world, she instantly converted the diamond into cash, starting a new life of raising her siblings and paying off debts.

The second time the shop appeared, it was at a large energy auction. Wen Zhi's item for sale? A mud-stained shovel. The entire venue erupted in an uproar. "This is actually an S-grade rare energy item!" "I'm willing to offer 100 million star coins!" "100 million? How dare you offer so little? It's worth at least 1 billion!" But the same male beastman from before, with deep eyes, coldly bid, "10 billion, plus 10,000 of those stones from last time."

After the third, fourth... and countless more times, Wen Zhi suddenly realized something. She asked the male beastman, who had appeared before her yet again, "Why does my little shop always appear around you?" The male beastman reached out and caressed the back of her neck, lightly inhaling the unique, sweet scent that soothed his spiritual energy. "Because I am your possession. Where you are, there I am."
