Main Characters: Su Ling + Calico Cat

After waking up, Su Ling's grocery store was bound to the plane trading system and he traveled through the book.

The first world in the book: the Koi Age.

A grocery store suddenly appeared on the back mountain of Dawang Village. The things in the grocery store were more and cheaper than those in the supply and marketing cooperative. There was white refined rice, clean flour without a trace of impurities, and unlimited brown sugar milk powder for purchase. The whole village was delighted.

The second part of the book: ancient texts about fleeing famine.

The land was dry and not a drop of water could be found in the dry wells. The whole village, young and old, tightened their belts and prepared to go to the county town to buy expensive grain and quickly pack up to escape the famine.

Suddenly, a shop appeared on the back hill. The floor was spotless, and the windows on both sides were made of glass. They sold food that they were in short supply of, and the prices were reasonable! I bought it!
