Pei Changsheng took advantage of the situation and handed over a fake sword manual with a key page torn off, and secretly made thousands of copies and spread them around the world. At the Lingshan Sword Discussion, when everyone was obsessed with practicing fake sword manuals and reaped the consequences, Pei Changsheng shocked the audience with his Nine Yang Magic, revealed the truth, and finally took the position of leader of the martial arts alliance, completing his revenge and reaching the top.
