There was indeed such a rule in all the sects.
Should new disciples ask senior brothers and sisters for guidance, they could set a certain remuneration in exchange for a little teaching.
However…
How was Zhou Qu giving guidance?
It was clearly an arena he set up, yet he shamelessly worded it so nicely now.
Ultimately, he found such an excuse only because he was frustrated over losing the Xi Spirit Pills to Ye Qingtang.
At that point, there were significantly fewer people in the Rewards Pavilion. In the wide first floor, only Ye Qingtang and Zhou Qu remained. With the warden in charge of the missions currently on the third floor, no one could say anything even if Zhou Qu were to act arrogantly.
"Junior Sister Ye, I gave you guidance so kindly. It cannot be that you don't even know about such manners?"
