Su Ya was just being an absolute thug!
[You are saying that this woman is poking my hands into the affairs of the disciples?]
[But too bad for you, before they had even starting to fight this woman had already thrashed him up properly. So if you were to base it on the sequence of events, this woman had beat him up first.]
Su Ya's highly tyrannical manner refuted all the words that Gu Ying had said completely and Gu Ying had initially planned to draw Jun Wu out but Su Ya had not budged in the slightest in her defence of her disciple but heaped all responsibility onto herself which completely shattered Gu Ying's plan in an instant.
