"How did you know there was money inside?" Yang Xiao asked again.
"I've helped Fu Changxue with that briefcase before. I secretly felt through the bag, and there was something shaped like a wallet inside," Li Qingxuan explained in a low voice, "I thought that kid dressed rather well, so I assumed there had to be at least 100 yuan inside, but it turned out to be just this little."
Yang Xiao looked Li Qingxuan up and down, "Tell me the truth, do you have a side job in the real world?"
"I don't, I swear I don't!" Li Qingxuan raised his hand to vow.
Yang Xiao looked at the 10-yuan note in his hand and eventually accepted it, "Your kindness is rare, so I'll take this money. This is a 10 yuan note, and none of us currently have a denomination this large. If it remained with you, once Fu Changxue realizes it's gone, you would inevitably fall under suspicion."
