I was accidentally bound to the "modern supermarket" system, and I became the little ancestor of my family in the 1970s when we were short of food and clothing.
Lin Shu, a modern supermarket buyer, dressed as a doormat from the 1970s, relying on the "space-time supermarket" bound to his body, using materials to crush the best products, while quietly making a fortune in that simple and fanatical era, and taking a cold-faced military officer as his backer.
Concept: A supermarket buyer who is well versed in modern business logic and sophistication brings an inexhaustible modern supermarket back to the 1970s when supplies were scarce but full of opportunities. She is not only a material "divine", but also a "life advocate" who uses modern thinking to reduce dimensions, transform backward production relations, and warm people's hearts.
