Episode 21 recap: Lin Xi Yao's tea party was plagued by troubles.

In fact, Du Wenshu had a large tattoo on his body, but it was usually covered up and had not been discovered. He was actually a member of a mysterious organization. Hua Qing Ge finally managed to get rid of the personal protection maid assigned to her by Ji Chu. However, as soon as she went out, she overheard Ji Chu arranging a secret operation for that evening. Hua Qing Ge was curious, so she followed him.

She discovered remnants of gunpowder on the ground, indicating that something significant was indeed going to happen that night. Initially, Hua Qing Ge thought Ji Chu had given up his violent ways, but she was shocked to learn that he was plotting something even bigger. Hua Qing Ge panicked and quickly went to the warehouse to investigate, where she found a large quantity of gunpowder. Terrified, she hurriedly poured water on the gunpowder.

When Hua Qing Ge heard someone approaching, she quickly hid and overheard them discussing the formal action to be taken the next day. Hua Qing Ge wondered if Ji Chu was planning to rebel. Lin Xi Yao encountered Ji Yun just as she was about to enter the palace. Ji Yun invited Lin Xi Yao to accompany her along the way. When Hua Qing Ge passed by, she saw Ji Wan Er, who was complaining about Gong Ye Qi not paying attention to her.

After comforting Ji Wan Er for a while, Hua Qing Ge went to find Ji Chu. After all, this time she was going to the banquet venue with Ji Chu as the queen. When Ji Wan Er saw Lin Xi Yao coming in a coroner's attire, she hurriedly asked about it. Lin Xi Yao mentioned that she had just solved a case involving a headless female corpse, which caused a discussion among the other ladies.

Soon, the Empress and her entourage also arrived. Although it was officially a tea tasting banquet arranged by the Emperor, it was actually a blind date for Ji Yun, and Ji Chu was asked to see if there was anyone suitable. However, Ji Yun's gaze never left Hua Qing Ge. Hua Qing Ge cooperated well with Ji Chu, showing their affection.

At this moment, a girl at the tea party noticed Lin Xi Yao and felt a sense of foreboding. At first, the Empress didn't understand, but later she realized they were talking about Lin Xi Yao. Hua Qing Ge and Ji Wan Er quickly stepped forward to plead for Lin Xi Yao. Just then, Duke Ding Guo arrived and quickly informed the Empress that Lin Xi Yao was actually his long-lost daughter. At first, Lin Xi Yao was very surprised, but after hearing Duke Ding Guo explain the reason behind it, she realized that she might indeed be his daughter. However, even so, Lin Xi Yao couldn't accept it for the time being.

Now that Lin Xi Yao's identity was confirmed, Hua Qing Ge took the opportunity to speak highly of her, hoping that the Empress would take a liking to Lin Xi Yao and facilitate a good match for her in the future.

Du Wenshu disguised himself as a guard and entered the palace, but he was quickly discovered as soon as he left. There was a black-clad person prepared to assist Du Wenshu, but upon seeing him being captured, they quickly retreated.

After the banquet, Ji Chu took Hua Qing Ge away, while Ji Yun prepared to escort Lin Xi Yao back home. Lin Xi Yao still had some difficulty accepting her own identity, but after today's events, Ji Yun developed a favorable impression of her. Lin Xi Yao already had a liking for Ji Yun, so they had a long conversation, which made her very happy.

Hua Qing Ge was surprised that Ji Chu had successfully captured Du Wenshu. The two of them sat by the river, and Ji Chu had initially arranged for fireworks to be set off. However, after just one firework, they suddenly went out. Hua Qing Ge suddenly realized that Ji Chu had intended to set off fireworks.

Ji Chu also admitted that the reason he set off fireworks was because he liked Hua Qing Ge. Hua Qing Ge was extremely surprised by this and never expected that Ji Chu would develop feelings for her. The next thing Hua Qing Ge needed to do was to search for the totem on the tattoo, which would help identify who wanted to frame Ji Chu. Unbeknownst to her, Hua Qing Ge started to feel that Ji Chu wasn't as detestable as she thought and even developed some positive feelings towards him.

Ji Chu interrogated Du Wenshu, but he remained silent and didn't say anything. Ji Wan Er brought a book with various totem drawings for Hua Qing Ge to use as a reference, and unexpectedly, Hua Qing Ge found a matching totem. As Du Wenshu was unwilling to speak, Ji Chu had no clues to work with.

After returning, Hua Qing Ge shared the secret of the hidden totem with Ji Chu, hoping it would help him find the culprit quickly. Ji Chu clearly noticed that Hua Qing Ge cared about him, but she still refused to admit it.
