Wisdom.

The scream belonged to Rectus, he was smacked by a vine whip, however, the shocking thing was that the holder of the whip was not Valerian. Rectus did not see how he got hurt, and he looked at the young boy and said indignantly, "You brat, you are getting too ballsy, do you really think I will not beat you up?" 

Valerian sighed and then raising his hand he said, 'You are thinking too much, I am not the caster of that whip.' 

Azula was taken aback as well, she also thought that it was Valerian who cast that spell. Rectus did not believe him and said, "You have learned to lie as well?" 

As soon as his words dropped, another scream sounded as he was whipped again and this time it was harder than before. He rubbed his butt as he jumped around in the room. The scene was so hilarious that Azula forcefully held her laughter. Rectus said, "You did it again, if not you, then who did this? The princess, the cat, or do you think I am a masochist?"
