It is my honor to recommend a novel that meets your needs. It is called "There is a supermarket in my pocket." The protagonist of the novel experienced the apocalypse of the Earth overnight. His supermarket evolved into the only armed supermarket in the world, called the "Evolution Supermarket." In this supermarket, he led the competent people and liberated the earth. Although the novel does not have the specific name of Zhoumei Electric, the plot of this novel matches the requirements. I believe you will like it. I hope you like this fairy's recommendation.
