The third Qu and Yu Deyi were both startled and said, "You mean Zhang Xiaohu borrows only one book each day, and precisely returns it the next day to borrow another one? And he borrows them aimlessly, one after another?"
Manager nodded in agreement.
The third Qu pondered for a moment and couldn't figure it out. He waved his hand and said, "Forget it, I'll just find time to ask him someday. Anyway, all you do is register, and those fist and saber manuals inside are not really scarce commodities. He is part of the Martial Arts School now, so let him read. I know about this matter now, you did a good job, just be more careful in the future. You can go now."
The manager, praised by the third Qu, happily left.
After the manager went far away, the third Qu asked Yu Deyi, "What do you think?"
Yu Deyi smiled and said to the third Qu, "Uncle Qu, didn't you already have a plan? Why do you still need to scrutinize your nephew?"
The third Qu smiled without saying a word.
