In New the duke of mount deer, the reason why Jiu Nan, the master of the Naked Son, sent the Naked Son to assassinate Wu Sangui was more due to his surrender to Wu Sangui and hatred for the Manchu Dynasty. Jiu Nan was once the nine princess of Emperor Chongzhen. When her country was destroyed, she was saved by Yuan Chengzhi. After that, she became a teacher. Although she has become a nun, it is difficult for her to let go of the disputes in the secular world. Her feelings for Yuan Chengzhi are buried in her heart, but her hatred for those enemies is growing day by day. Although the death of Emperor Chongzhen was due to Zhuang Wang Li Zicheng, Wu Sangui also had reasons. If he could divide his forces to help each other, Emperor Chongzhen would not commit suicide or be beheaded. Jiu Nan has no resentment against Emperor Chongzhen. She knew that her father was doing her good, and she didn't want her to fall into the hands of her enemies and be humiliated.

Later, Wu Sangui surrendered to the Qing Dynasty and gave the land of the Han people to others, which was unacceptable to Jiu Nan. Otherwise, Nan Ming will support you. In order to win the trust of the Qing Dynasty, Wu Sangui personally destroyed the Nanming court, so he was also an enemy of Jiu Nan. Although Jiu Nan's martial arts skills are high, there are many masters around Wu Sangui to protect him. It is very difficult to assassinate him in secret. At this time, Wu Sangui has won a great victory. It is too cheap to kill him.

So, Jiu Nan took Ako away as an infant, taught Ah Yi the national righteousness, made Wu Sangui's daughter grow up, and personally killed her father who betrayed the country and sought glory. Jiu Nan's original intention was revenge, but in these years, he also had a mentoring relationship with his aunt. As he grew older, Jiu Nan gradually realized that the grievances of the previous generation should not be implicated in the next generation. After meeting with Wei Xiaobao, the truth of all the facts surfaced. It turns out that Hui's biological father is not Wu Sangui, but King Li Zicheng. Although they were all enemies of Jiu Nan, Jiu Nan chose to let go. At the same time, Jiu Nan also gave up the plan to assassinate Emperor Kangxi. She let go of her hatred and spared herself.
