Xie Shan was especially brutal towards the demons and evildoers he recognized. Once his Nine Heavens Duoluo Divine Blade was unleashed, it could shred both people and treasures into dregs!
In Shu Mountain, it's rare for high monks and Divine Nuns to kill people. Those who have not taken vows to become monks or nuns are also quite vicious when acting. Take Yang Jin, for example, a disciple of Fen Tuo. When dealing with demons and evildoers, her blade would come out swiftly, cutting people into pieces. If that wasn't enough, she'd deploy Fen Tuo Master's Mountain Treasure, the Dharma Flower Vajra Wheel, and grind people to dust.
Yuan Hua, once taken as a disciple by Shi Feiyang, ended up as nothing more than a Ghost Immortal with only his essence because he met his demise at the hands of nun Su Yin. Su Yin was a disciple of Master You Tan, and even as a nun who had taken vows, she was deadly.
