@Guntai If the Yun Lan sect has decided they want to be enemies with Xiao Yan, who is going to convince them otherwise? You can't convince the corrupt with words alone. Just look at their attitude: They are the ones who attacked Xiao Yan's brothers first, but now they appear here, accusing Xiao Yan, with such pompous sanctimoniousness.
No matter what he said, they would twist it or turn it around on him. They had made up their minds to kill him a long time ago. They need to cover up their evil actions by silencing him permanently.
