Honestly, that Su Chengde from Mount Heng is clearly a ruthless bastard too, no? A proud disciple of Xuanmen, yet he doesn't know the difference between a scratch and breaking someone's bones in a friendly competition?
The Nangong women standing beside him must be the reason for his heavy-handedness in the absence of any blatant grievance with Mo Zhu Mountain or any personal karma with Su Chengde. He's just showing off in front of them.
No need for further talk, then. Since we're all mixed up with the Nangong Family now, there's no point in reasoning. I've taken note of those teachers and students; they're all red-named monsters opposed to me, Li Fan. Most of these ancient method cultivators may look young, but they're actually several hundred years old. They've lived long enough; if I get the chance, I'll take them out as a way to lighten my mood.
