Wei Zhuang (Chinese: 卫庄; pinyin: wèi zhuāng): A former student of the Guigu ("Ghost Valley") School who studied alongside Ge Nie. They are rivals and his swordsmanship is just below that of Ge Nie who he unsuccessfully sought to defeat. The Qin Emperor's Advisor has hired him to hunt down Jing Tianming and his friends. During the battle with Ge Nie in the Machinery City, he breaks Ge Nie's sword with his sword Shachi (Shark Teeth). Both men were wounded badly after the duel.
