from a recent thread, it was mentioned that RYY is smarter than LHC. I don't think so because from the impression i had from reading the novel both has their own intelligence qualities like RYY is more alert, vicious, better at interpreting situations , like why YBQ invites ppl to the cave to learn martial arts, LHC is only naive in his thinking compared to her but he takes thing easy ( like the sky collapse , he use it as blanket), this is what RYY fail , he also has comparable wits and alertness in battle like he use slow mo to kill ZLC LPZ to avoid their sharp hearing.
