Da Qin: a Salted Fish Merchant Mistook the First Emperor for His Younger Brother

Lin Yi traveled to the Qin Dynasty. I wanted to do some errand to make a living. Unexpectedly, I met a person asking for directions, and the two had a great conversation.

At this time, Lin Yi didn't know that this person was the legendary First Emperor.
