Eighteen years ago, Cai Yingjie's father, Changshan Gong, was the supreme in Wulin, and his soul-chasing sword was an artifact that people in Wulin dreamed of. One day, he led Liu Xiang and others to grab the sword. Except Yingjie, the whole family was killed. In order to get revenge, Yingjie learned from his teacher and went down the mountain to visit his enemies.
Yingjie beheaded Zhou Hu and Fang Bao one by one, but was poisoned while fighting with Indian lions and Liu Xiang. Fortunately, she was saved by the heroine Fei Yanzi (Lingfeng ShangGuan) and her senior Zhao Jizhong (Jiangnan). Feiyan asked Master for an antidote to cure Yingjie. It turned out that Xiao Feiyan had been looking for orphans in order to atone for his father and settle the grievances for many years. However, Zhao Jizhong was jealous of Yingjie's swordsmanship and made an appointment to duel.
Yingjie finally got the whereabouts of the gentleman in the cloud and came to intercede. At this time, YunZhongJun was old and weak, and his eyes were blind. Over the years, he felt deeply guilty about the murder of the sword that year, and was even willing to apologize for breaking his arm and return the soul-chasing sword to its original owner. But Yingjie insisted on a showdown with YunZhongJun. When the two sides were fighting, Feiyan seemed to stop pleading. It turns out that Feiyan is the daughter of YunZhongJun. Yingjie remembered that it was the gentleman on the cloud who spared his life and resolutely took away his sword.
Yingjie and Zhao Jizhong meet in Skull Bay, and the Black Dragon Man loses. Yingjie thanked the past for saving his life, but only cut Zhao's clothes and didn't hurt his body. Zhao boasts that he is the best sword in the world, so far, he is honored as Yingjie and the real "sword king of the first generation".
