He, along with Erzhuzi and Liu Xiaolian, turned around and bolted.
"Chase them!" the boy holding the dagger shouted, and his gang pursued like maniacs.
After half a day of pursuit around the street corners, they finally cornered An Ping and the other two in a narrow alley.
An Ping looked around and realized there was no escape, so he simply stopped running.
He caught his breath and asked, "What do you want to do? I don't even know you! Why are you cornering us? Hey, have you mistaken me for someone else?"
"Mistaken? Hmph, I'd never mistake you, even if I beat you to death!" The boy played with the knife in his hand, its gleaming blade reflecting the sunlight with blinding sharpness, "My name is Shi Yan. My dad is Shi Jianjun, who used to be the vice principal at Changzheng Middle School! Get the picture now?"
With those words, An Ping instantly understood.
