Once Upon a Time There Was a Grocery Store

I heard that once upon a time there was a grocery store. The owner was a god, but he made a mistake and was demoted to earth. The owner was kind-hearted and very popular among the people. The Jade Emperor found out and did not let her return to heaven. Instead, he gave her the right to live forever so that she could benefit the people forever. From then on he lived a happy life with the common people. This story was told by grandma to Shen Ming, and she has been hearing it since she was a child. Until one day, Shen Ming met a grocery store owner, and something strange happened... This novel and its characters are purely fictitious.
