Supermarket stock clerk Lin Bei wakes up one day in an ancient wasteland suffering through its third year of drought.
Fortunately, the supermarket where he worked transmigrated with him. Instant noodles, bottled water, cold medicine, you name it, it's there.
Unfortunately, the supermarket only has enough electricity to last seven days.
Even better, he discovers that the supermarket's doors can take him back to the modern world.
By day, he sells instant noodles in ancient times for silver. By night, he returns to the modern world to restock, making a fortune.
Instant noodles become imperial cuisine, glass cups become national treasures, and one bottle of Erguotou is enough to make a prince call him brother.
But just when he finally becomes richer than the country itself, someone tells him:
"You didn't transmigrate here. You came back."
[The hook in one sentence]: With a single supermarket, become the richest man in two worlds.
