Chen Yuan took over a 24-hour convenience store left by his grandfather. During the day, they sell cigarettes, alcohol and snacks, but at night they do not necessarily serve all living people.
There are all kinds of visitors late at night - there is a 90-year-old man buying the last pack of candy for his wife, a construction worker buying a birthday gift for his daughter, and there is also the darkness crawling in the shadows. Convenience stores are the intersection of yin and yang, and Chen Yuan is a new generation of night watchmen.
A dark golden seal, nine ancestral techniques, and a half-written training diary. Grandpa kept it for fifty years, leaving behind an agreement that spanned half a century. Chen Yuan wants to keep not only this store, but also the promise made by his grandfather and the man named Lao Zhou under the big locust tree.
"This tree can live for a thousand years. Let's keep it for a hundred years and see."
Concept: "Late night convenience store, the intersection of yin and yang."
