Ning Yuanzhou asked Ruyi why he left and came back, and for this reason he also exposed his martial arts. Ruyi said that she killed Lou Qingqiang to avenge Linglong, and Ning Yuanzhou did herself a favor by killing Zhao Ji. She didn't like to owe favors in her life, so she returned to save Yuan Lu. Ning Yuanzhou sent Ruyi out of the city gate, but Ruyi did not intend to leave alone. She said that she knew a lot about An Guoguo, and in return she could know Mr. Yue's true identity by entering the mission. Ning Yuanzhou told Ruyi the information he obtained about Mr. Yue, and speculated that Mr. Yue was at least the purple envoy among the Zhu Yiwei. Ruyi originally wanted to ask Ning Yuanzhou to help investigate a matter, but Ning Yuanzhou refused to help and believed that the mission did not lack an assassin like Ruyi, so the two parted ways.
Liudaotang Tiandaoti rides Jiang Qiong back to Liudaotang. Ning Yuanzhou arranges for Jiang Qiong and Lao Du to sit in the main hall to support the mission at any time. Then Ning Yuanzhou left Wu State and headed for Anguo with a delegation of four including Yu Shisan. After Emperor An captured the three cities of Xu, Cai, and Jing, he led the An army back to the court. The second prince of An State, Li Zhenye, King of Luoxi, and the eldest prince, King Li Shouji of Hedong, came to Guideyuan to welcome him. Li Tongguang's meritorious service in capturing the emperor of Wu State was great. Concubine Chu believed that this achievement was enough to make him a marquis. Li Shouji, the king of Hedong, objected on the grounds that although Li Tongguang was of princess blood, he also had the humble blood of Wu people. Emperor An did not say much about this.
Li Tongguang was in a bad mood because he was ridiculed about his origin. Concubine Chu came to comfort him late at night. Emperor An originally married Concubine Chu for the power of Shaxi, while Concubine Chu was attracted to Li Tongguang. Li Tongguang gave the phoenix hairpin obtained by capturing Emperor Wu alive to the first noble concubine, hoping that she would ascend to the phoenix throne as soon as possible. Li Tongguang agreed to cooperate with Concubine Chu because he did not want another war. He only wanted Haiyan and River to be clear.
Ning Yuanzhou and his party caught up with Yang Ying and others. Yang Ying was afraid of being assassinated. Ning Yuanzhou arranged for Sun Lang to protect Yang Ying's safety. He would also forge Yang Ying's identity to cooperate with the mission. Ning Yuanzhou introduced the six cousins to Yang Ying. Du Changli and Ming female officials who accompanied Yang Ying on the mission were very strict with Yang Ying, which made Yang Ying quite distressed. Yang Ying knew little about Anguo, and Du Changli and the Ming female official had no good plans for Anguo and his party.
Ning Yuanzhou guessed that King Danyang did not want Yang Ying to return home safely, so he asked Du Changshi, who was clueless, to accompany him. Now that he could not replace the female officer, Ning Yuanzhou thought of Ren Ruyi and sent a letter back to the headquarters to investigate Mr. Yue's whereabouts. At this time, Mr. Yue also took Yulang to the Kaiyang branch of Zhu Yiwei to find Ruyi's whereabouts. At this time, someone pretended to be Ruyi and came to the Kaiyang branch. Mr. Yue planned to arrest her, only to find out that this person was an imposter. People from the Zhu Yiwei branch confirmed that Zuo envoy Ren Xin must have identified them, and then he was assassinated and died.
Mr. Yue was afraid of Ren Xin, so he hurriedly left the Kaiyang branch with his money and wanted to return to Anguo safely. At that time, Ren Xin became the left envoy of the headquarters from a small Zhu Yi Zhong, and was also the most successful assassin in the history of Zhu Yi Wei. Five years ago, she assassinated Queen Xianzhaojie due to sudden misfortune. After being surrounded, she burned herself in the palace. However, Mr. Yue never expected that Ren Xin was still alive.
Ren Ruyi designed to lure out Mr. Yue, and subdued Mr. Yue with just a few moves. Yulang saw the danger and ran away. Mr. Yue revealed that he was Yue Sanniang, the purple envoy of the Wuguo branch. Yue Sanniang said that she was following the orders of the headquarters. Betrayed the Wuguo branch, resulting in the death of forty-seven people. There was someone in the headquarters who was greedy for money. In order to make up for the vacancy, Yue Sanniang would cooperate with the people of Liudaotang to make money.
Yue Sanniang saw that Ren Ruyi's internal strength had not yet recovered, and took action against Ren Ruyi. Ren Ruyi was injured due to lack of internal strength. At the critical moment, Ning Yuanzhou came with Yuan Lu to help, and Ren Ruyi also successfully killed Yue Sanniang. Ning Yuanzhou agreed to cooperate with Ren Ruyi. Ren Ruyi would help teach His Highness about Anguo, and he would also help find out the real culprit behind the death of his benefactor. The two reached a cooperation, and Ren Ruyi revealed his real name, Ren Xin. Ning Yuanzhou and Yuan Lu were both surprised by this.
Emperor An made Li Tongguang the first-class general of the Yulin Guard for his military exploits, but then Li Tongguang overheard in the dark that Emperor An promoted him to defeat the two princes, and made him take charge of the Yulin Guard to detain him in the capital. Li Tongguang knew that Emperor An deliberately let him hear this conversation, and he also deliberately got angry in public. Although the first imperial concubine had a crush on Li Tongguang, Li Tongguang had always been unwilling to get close to her. When the two were meeting, they were seen by a maid. Li Tongguang found this person and wanted to kill her, but he did not expect that the maid was Liuli, a former Zhu Yiwei woman and knew Li Tongguang.
