The street was bustling with people, and Gou Yazi had walked this road he didn't know very well many times. He struggled to give way to passers-by, thinking about which fork in the road he should take to get to the inn.

Before he opened his mouth, the guy looked impatient: "Young man, I've shown you this road dozens of times, right? Why can't you remember it? Have you also forgotten who I am?"
