Episode 18 recap: Liu San Niang was surrounded, and the Seven Righteous Ones cut their robes and fled in different directions.

Liu San Niang held her sword and ran wildly, but ultimately, she was surrounded. Soon after, Wu Lian appeared with Xie Zhi Hui, making the enemy even more jealous. Wu Lian teased Liu San Niang, suggesting they return to the Yanyu Embroidered Tower. Liu San Niang swung her sword towards Wu Lian, but in the next moment, she was knocked down by a guard beside her.

Seven years later, Meng Wan caressed the tombstone of Rulan, contemplating the words spoken by the abbot of the Qingshui An Temple. Bringing up past events, if innocent people were implicated, it would be Meng Wan's fault. However, if she had to give up everything she had fought for over the years because of a mistake, she felt unwilling to do so. Meng Wan stood up, gazing into the distance, lost in thought.

The incident with Zheng Da Niang Zi worried Meng Wan even more. She feared that if she continued to be entangled with Wu Lian, more people would be harmed, which was not what she wanted to see. However, San Niang believed that sacrifices are inevitable when great things are accomplished, and Tian Xiao Ling's role in bringing down Wu Lian was crucial—she should sacrifice herself for justice. Upon hearing this, Li Chun Feng next to them angrily smashed his wine cup on the ground, insulting San Niang as a lowly woman. The atmosphere became tense, and Meng Wan hurriedly interrupted their conversation.

On this day, someone delivered a secret letter, inviting San Niang to Tian Shui Tea House. However, only Meng Wan and their group knew San Niang's whereabouts in Huai Zhou City. Who could it be? To unravel the mystery, San Niang went alone to the Tian Shui Tea House for the appointment. As she suspected, the person who invited her was Wu Lian. Not only did Wu Lian know San Niang's whereabouts, but he also knew the secrets of all seven of them, even the details of their conversations in the courtyard.

After a long time, San Niang returned to the courtyard, only to be stared at by the others. It turned out that Li Chun Feng saw San Niang meeting with Wu Lian and suspected her of betrayal. San Niang sneered, recounting today's events in detail and bluntly stating that some of them had already been bought off by Wu Lian. As soon as these words were spoken, doubts arose in the hearts of the seven individuals, each pointing out the person they suspected. In the end, the seven of them dispersed without harmony.

That night, San Niang packed her belongings and prepared to return to Xunzhou City. Meng Wan tried to persuade her, but it was in vain. Helpless, San Niang asked Liu Xin to keep an eye on the surroundings of the courtyard to find out who the traitor was. Liu Xin wandered through the bamboo forest and accidentally discovered San Niang, leading him to suspect her. San Niang rolled her eyes and questioned why she would eavesdrop if she were a spy. So, they decided to work together and guard the courtyard.

Before long, San Niang spotted a suspicious woman and quietly followed her. As a result, she overheard Wu Lian's next move—tomorrow, Wu Lian would head north to seek support of 300,000 troops. San Niang quickly left and informed Meng Wan of this information. However, in the end, San Niang decided to leave. Just before leaving, she handed a pair of shoes to Meng Wan and asked her to give them to Liu Xin.

Back in Xunyang City, when San Niang saw the familiar peacock and the longing Yuan Mei, she felt a sense of belonging. She discussed the situation in the capital with Yuan Mei and suddenly realized that the 300,000 troops Wu Lian mentioned referred to the Imperial Army. Now, San Niang was faced with a dilemma. She had to ask Yuan Mei whether she should go to the capital, knowing that she might never return. Yuan Mei simply advised her that if her heart was tied to it, she should go, and if she couldn't come back, she would go search for her together with the peacock.

Upon entering the capital, Wu Lian headed straight to the Dali Temple, apparently looking for an acquaintance. After arriving in the capital, San Niang first sought out her old friend Luo Qiong and asked her for help to enter the Forbidden Army Camp. Although Luo Qiong didn't know the Forbidden Army, she knew some courtesans. As a result, San Niang infiltrated the camp and uncovered the connection between Wu Lian and the Forbidden Army. She quickly wrote down what she had heard and entrusted Luo Qiong to send it out. To protect Luo Qiong, San Niang had to take risks.

Luo Qiong rushed out of the camp and collided with Liu Xin. Since Luo Qiong had also stayed in Huaizhou City in the past, she naturally recognized Liu Xin. Following San Niang's instructions, she handed him the secret letter. Upon receiving the news, Meng Wan couldn't understand why Wu Lian, a high-ranking official in the Zhi Ma Hall of the Imperial Palace, would go to such lengths to seek this position. After much deliberation, the only possibility was that Wu Lian's true target was the Right Temple of the Dali Temple—the specialized court for handling criminal cases of the capital's officials.
