So this might be considered a non-purposeful mistake by Hong Yu, but Lan Ruan felt in his heart that things could be more sinister than imagined. However, without evidence, he dared not accuse or beat Hong Yu, for this boy is still a disciple of Elder Han. Hitting Elder Han's face using his master's power is one thing, but it's different when it is Lan Ruan himself hitting Elder Han's face.
Lan Ruan's master would probably punish Lan Ruan for that! Ahh, the master's punishment was very scary!
Not to mention that the damage is being dealt out right now, guilt and punishment could wait until this tournament, which was more like a talent-exposing game, was over before moving against Hong Yu or anyone else.
