My Corner Shop Connects Past and Present: I Became a Middleman in Ancient Times

Chen An, an overworked wage slave, takes over a little shop on the verge of closing, only to discover that its back door leads straight to an ancient world ravaged by famine. Modern industrial goods in his left hand, including near-expiry food, glass marbles, and antibiotics; real gold and silver from the past in his right. No bleeding-heart heroics, no saving the world: he is here to be the ultimate middleman.
