Xin Hong is a friend of Xiang Ying from childhood and was referred to as Number 36 during training for the Zhuque Corps. He has developed feelings for Xiang Ying, which led to them facing off in a fight to the death during their final exam. Despite killing his only friend, Xiang Ying, Xin Hong survived and was transferred to the Qinglong Corps, another branch of Zheng Dao Hui. His motivation to reunite with Xiang Ying has driven him throughout this time. After the Qinglong were killed off by the Xuanwe, Li Jiang Qiang allowed Xin Hong to live a normal life in order to watch over Xiang Ying. Incidentally, Xin Hong was also the assassin who sniped Li Qian De through his hotel room window. However, Li Jiang Qiang did not hold him responsible for his brother's death, understanding that he was trained to follow orders and most soldiers and assassins under him do not know their leaders.
