Ye Shi'an and Gu Jiusi knew very well that what Luo Zishang was best at was stirring up the situation behind the scenes and bewitching people's hearts. No one knew his true face and thought he was bearing the burden of humiliation, so his prestige was quite high. Since he dared to appear in Dongdu openly, there must be his reasons. Gu Jiusi thinks that Luo Zi traded Yuzhou for the position of Prince and Taifu, which is to place the bet on the prince. This is what Gu Jiusi is most worried about. Soon, Luo Zishang went to meet the Queen Mother and advised her to let Princess Yunshang marry Gu Jiusi. Li Yunshang, the former princess, went to see Gu Jiusi, and she called Jiusi's brother one by one, so enthusiastic that Gu Jiusi panicked. Just as Ye Shi'an sent someone to look for him, Gu Jiusi immediately left with an excuse.
Liu Yuru received a post from the palace, inviting her to a banquet in the palace to enjoy the flowers. Liu Yuru felt strange, why this princess Yunshang came out to play the emotional card when Gu Jiusi was thoroughly investigating Ku Yin. Even though she knew there was something wrong with it, Liu Yuru decided to go to the meeting, and she even called Qin Wanzhi together. Outside the palace gate, Liu Yuru and Qin Wanzhi saw Luo Zishang and greeted him casually. Qin Wanzhi didn't know Luo Zishang, and Liu Yuru called him a poisonous snake that only dared to hide in the shadows. At the banquet, the princess made things difficult for Liu Yuru, and Qin Wanzhi stood up to speak for Liu Yuru. Liu Yuru and Qin Wanzhi sang together, accusing Yun Shang of being arrogant and extravagant, spending thousands of taels to hold this flower viewing banquet.
The emperor appeared and praised Liu Yuru's words well, but Yun Chang's face was livid, but he didn't dare to refute. Not long after, the dowager came to the emperor and proposed a marriage for Yunshang and Gu Jiusi. As for Liu Yuru, it was just a divorce. The Empress Dowager brought up the matter of meeting each other in Kaesong, and secretly forced the Emperor to make a decision. The emperor did not directly agree, but only said that he would ask Gu Jiusi for her. In front of the Empress Dowager, Gu Jiusi said that he and Liu Yuru played in harmony, and they were very affectionate. He was eloquent, and with a few simple sentences, he had enough reasons to refuse the marriage proposal. In addition, the emperor also wanted to help him, so he wrote "a match made in heaven" and sent it to Gu Jiusi. The queen mother was so angry that she had nothing to say. Princess Yunshang was furious in the palace and wiped everything on the table.
Afterwards, Liu Yuru thought about it carefully, and always felt that this four-two-handed method was very familiar. Gu Jiusi said Luo Zishang's name with a tacit understanding. The forces in the Eastern Capital are deeply rooted, so Gu Jiusi decided to consult Uncle Jiang He who was in prison. Jiang He talked to Gu Jiusi for a few words, but he knew that Gu Jiusi was not thinking well enough, so he didn't say anything. Luo Zishang gave Lu Yong an idea to try to kill Liu Chun, and then blamed the incident. Later, Luo Zishang took advantage of Fan Yu's eagerness to win the emperor's appreciation, and persuaded Fan Yu to intervene in the thorough investigation of Ku Yin's case. Shen Ming wrote a lot of Ye Yun's rhyme characters on the paper, Ye Shi'an felt that something was wrong, Gu Jiusi tried his best to brainwash him because he was thinking too much.
Dongku's account is full of loopholes, but the account is flat. Ye Shi'an thinks that the person who made the account must have other means. After discussion and analysis, Gu Jiusi and Ye Shi'an thought that this man named Zhou Kai might be a breakthrough. Unexpectedly, they learned from Chen Qianzhong that Zhou Kai, the treasurer, retired from illness three years ago and died a year ago. As for Liu Zhe, the village he lived in had been flattened due to the chaos caused by the war the year before last, and now Liu Zhe is nowhere to be found. Gu Jiusi said, there is one more thing to check.
