My Grocery Store is Bound to an Interdimensional Trading System

Su Ling discovers that her entire life has been a fictional construct within a novel titled Lucky Koi Era. After learning that the world is on the verge of destruction due to the protagonist's destructive romantic obsession, she accepts a binding offer from a subsystem branch. Her mission is to traverse various worlds, operating a business to gather energy and ensure survival. She is transported to a harsh, snowbound era where food is scarce and temperatures are lethal. Upon arrival, she finds herself in a dilapidated hunter's cabin, which the system immediately upgrades into a fully stocked grocery store through a starter gift pack. Accompanied by Hua Hua, a talking calico cat who serves as her system interface, Su Ling prepares to open her shop to the local villagers.

The world is in the grips of a severe winter blizzard. The local population, including the Wang family and a group of educated youths, faces starvation and freezing conditions. Su Ling’s first customer is Wang Baozhu, a five-year-old girl who is the lucky koi protagonist of the original novel. Despite her young age, Baozhu displays remarkable fortune, digging up a valuable ginseng root in the deep snow. She trades the ginseng at Su Ling’s store, which provides enough capital for her family to purchase rice and flour. This initial transaction establishes the store as a lifeline for the village, drawing a steady stream of desperate customers seeking basic sustenance.

As business grows, Su Ling completes system missions by serving customers, unlocking rewards such as instant noodles, frozen meats, and underfloor heating. The store becomes a central hub in Dawang Village, offering goods that are otherwise unavailable due to the snow-blocked roads. The educated youths, including Xie Linfeng and his rivals, also frequent the shop, creating social tensions that Su Ling observes but does not actively intervene in. The narrative reveals that this world is a fusion of multiple novel plots, introducing a rebirth storyline centered on Wang Zhaodi, a girl who suffered greatly in her past life. Upon rebirth, Zhaodi seeks to change her fate, initially considering unethical means before deciding to work honestly.

A significant turning point occurs when an elderly man brings a vintage wristwatch to the store. Su Ling lists the item on the system’s interdimensional marketplace, where it sells for one hundred thousand yuan. This windfall transforms her financial situation, allowing her to invest heavily in inventory and infrastructure. She rents a snow-collecting machine and begins purchasing snow from villagers, providing them with a new source of income. This initiative stabilizes the local economy, as villagers can now earn money to buy food and supplies. The store expands its offerings to include clothing materials, household goods, and medical supplies, further cementing its importance to the community.

The story continues to explore the interactions between the various characters, including the lucky koi Baozhu and the reborn Zhaodi. Their paths cross at the store, highlighting the contrast between their circumstances and personalities. Su Ling maintains a neutral, business-focused stance, treating all customers with equal courtesy while managing the operational demands of her shop. The narrative sets the stage for further developments as the winter persists and the store’s role in the village becomes increasingly vital. Su Ling’s ultimate goal remains to accumulate enough energy to complete her missions and retire in a world of her choosing, all while navigating the complex social dynamics of this frozen, fictional era.
