'Seven Injuries Fist' (七傷拳): The most powerful of the Kongtong Sect's martial arts. The skill allows the user to inflict severe internal injuries on his opponent while suffering grave internal injuries at the same time. As the practitioner progresses from one level to another, he will hurt one of his vital organs even though his prowess is increased. Xie Xun stole the skill's manual from Kongtong in his desperate bid to seek vengeance on Cheng Kun. He practises the skill relentlessly without knowing the true adverse nature of mastering it. However, it was too late and Xie suffers from frequent fits of insanity as a consequence of neuroendocrine damage.
