When the Apocalypse Comes, I Open a Small Shop and Lie Down

Gu Yu was reborn twenty years after his death, which was the twentieth year after the end of the world and the mutants were raging. The sky is filled with yellow sand, smoke and dust are everywhere, devastated and ruined. The land is barren of grass and water resources have dried up. Human beings are living huddled underground in the darkness. They all look sallow and skinny, have no food to eat, and have no clothes on their bodies. They look lifeless. We have reached the point where we are running out of ammunition and food. The person who gave Gu Yu a new life was a black cat named Gou Chen. He asked for repayment and entrusted a small shop to Gu Yu. The shop can buy everything in the world: food, water, clothing, shelter, transportation, etc... As the owner of the shop, Gu Yu enjoys these unconditionally. With these, she lives an extremely nourishing life in the end of the world. The system in the store is called Xiaolan. In the process of getting along with each other day by day, Gu Yu discovered its unknown side and gradually unveiled the mystery between the store, the black cat, Xiaolan and herself. In this process, after going through many hardships, Gu Yu also gained love, family affection and friendship. Finally, I also learned the truth that was hidden forty years ago.
