My Family's Incense Shop Connects to an Infinite-Flow World

[No romance] After graduating from college, Xi Mufu returned to her hometown and inherited her grandfather's incense shop. At first, nothing unusual happened. That changed when two student-looking customers came in and bought the shop's most ordinary incense money. After that, things started to get strange. Trade notifications began appearing in her mind. [Trade with otherworldly customer complete.] [Item acquired +1] [Skill acquired +1] One day, as she passed a kindergarten, a drunk man took a little girl hostage. Special police arrived, along with a sniper. But the criminal had chosen an extremely concealed position, and the sniper couldn't shoot right away. Xi Mufu suddenly remembered a notification from an earlier trade. [Remote Retrieval: You can make any object you want disappear and bring it to you from up to 500 meters away. Usable once every 24 hours. Note: Living things are excluded.] Could she make the criminal's knife disappear? As it turned out, she won the gamble. In broad daylight, the dagger in the criminal's hand appeared directly in Xi Mufu's. With all eyes on her, Xi Mufu looked at the astonished police officer approaching her, opened her eyes wide, and murmured, “I can explain.” From then on, the incense shop became a hidden gateway to the infinite-world survival game. One stick of incense buys a chance to survive in an infinite-world realm. A stack of spirit money buys a demon's contract. In those worlds, spirit money becomes a top-tier rarity.
