My Supermarket Connects the Past and Present [Planes]

[Complete. Little angels who bought the whole story, please leave a five-star review QWQ] Blurb: Yun Chu was at a low point in both her career and love life, so she inherited her family's perfectly ordinary little supermarket as a way to escape. But on her very first day as its owner, she discovered that the place was not ordinary at all. Every night, a wooden door would appear out of nowhere, and customers dressed in clothes from different dynasties would come through. A little girl sold by her parents for two dou of rice clutched the bread Yun Chu gave her and devoured it. Drinking a carton of AD calcium milk, she hugged Yun Chu's leg and cried, saying she wanted to be her servant. A soldier from the Republic of China, about to go to war, offered his treasured wristwatch in exchange for rice and flour so his comrades could have a filling meal. A young wife from ancient times who was being abused by her husband clung to Yun Chu and wept uncontrollably. She drank cola and said she couldn't go on and wanted to jump into the river, then cried out, "Another bottle!" A certain general Yun Chu had treated refused to leave, insisting on becoming her guardian and bodyguard. Yun Chu: "...I just want to be an ordinary little supermarket owner!" My next story: A Guide to Running a Planar Supermarket. Rolling around and begging for follows~ After graduating from Yun Jing University, Yun Jing returned home to inherit the family business. Everyone said she had to be crazy to waste her best years cooped up in a little supermarket. Only Yun Jing knew that a wooden door in her little supermarket connected to countless worlds. Her little supermarket was a planar supermarket. Its customers came from all kinds of worlds: A girl who had transmigrated to a beastman world entered and immediately dropped to her knees in front of Yun Jing, tears of excitement in her eyes. "Bestie! You're my god!" Milk tea, hamburgers, chocolate, and of course, sanitary pads too. After all, your big sister owns an entire mountain of gold, so there's gold galore. A customer from a planet polluted so badly that no plants could survive stared at the potted gardenia on the checkout counter, eyes shining. "I want this beautiful, fragrant flower. Can I pay with the new mecha?" An ancient customer short on salt and food nearly drooled at the supermarket's two-yuan bags of table salt. The world of immortal cultivation... the world of the Republic of China... Faced with all the wonderful things her customers brought in, Yun Jing came to her senses and realized she seemed to have become a winner in life. Theme: She originally wanted to make money by opening a supermarket, but ended up opening one to help the poor.
