My Grocery Store Is Bound to a Cross-World Trading System

[No CP · No male lead · General store · Ensemble cast · A story about doing business in various novel worlds, with plotlines that help the heroine of each world]

[Main characters: Su Ling + three-colored cat]

When Su Ling wakes up, her general store has bound itself to a plane-trading system, and she has transmigrated into a novel.

First book world: a lucky-koi era novel.

A general store suddenly appears in the back mountain of Dawang Village. The goods in the store are even more plentiful than those at the supply and marketing cooperative, and even cheaper. White polished rice, flour so clean it has not a speck of impurity, unlimited brown sugar and milk powder that can be bought as much as you want—the whole village goes crazy with joy.

Second book world: a classical disaster-escape novel.

The land has dried up, and the dry well cannot find a single drop of water. The whole village, young and old alike, tightens their belts, prepares to go to the county town to buy expensive grain, and quickly gets ready to flee famine.

Then, suddenly, a shop appears on the back mountain. Its floor is spotless, with not a trace of dust, and the windows on the left and right are actually made of glass. Inside it sells exactly the grains and supplies they urgently need, and the prices are even reasonable! Buy it!
