Episode 20 recap: "To save Ning Yuan Zhou, Ruyi cut her wrist.

Jin Mei Niang disguised herself as a shepherd girl to sell sheep. Qian Zhao recognized Jin Mei Niang and knew she must have something important to discuss, so he took her inside. Jin Mei Niang apologized to Ruyi for arriving late, but Ruyi felt that Jin Mei Niang had come at the right time. Jin Mei Niang informed Ruyi that she had followed Ruyi's instructions and arrived at the inn. She recognized Liuli based on the earrings she wore and pretended to get close to her. Liuli approached Jin Mei Niang in an attempt to gather information about Ruyi.

Following Ruyi's instructions, Jin Mei Niang pretended not to know that Ruyi was still alive. She analyzed the situation for Liuli, explaining that if Ruyi was alive, Li Tong Guang would undoubtedly neglect Liuli. Therefore, it was in Liuli's best interest not to reveal the truth even if she knew it. Liuli also had her own selfish motives, which was why she pretended not to recognize Ruyi on that day.

After hearing Jin Mei Niang's revelations, Ruyi realized that Liuli didn't recognize her that day because of this information. Ruyi was puzzled why Jin Mei Niang had concealed this information when she had asked about it previously. Jin Mei Niang told Ruyi that Li Tong Guang's feelings for her were not just that of a master and disciple, but romantic. After Ruyi's supposed death, Li Tong Guang had gone mad. He bribed the guards to enter the scene of the fire and desperately searched for Ruyi's body. He hid Ruyi's body in a cave and visited to pay respects every 15th of the month. He also arranged numerous marriage proposals.

However, Ruyi didn't believe that Li Tong Guang had romantic feelings for her. Jin Mei Niang believed that if Ruyi wasn't interested in Ning Yuan Zhou, she would find a suitable husband for her. Yu Shi San overheard this conversation and wanted to inform Ning Yuan Zhou but was stopped by Jin Mei Niang.

Li Tong Guang came to the mansion to threaten Ning Yuan Zhou into handing over Ruyi. Ruyi exposed Li Tong Guang's dark intentions and told him that if he acknowledged their relationship, Emperor Anguo would never spare him. Furthermore, the position he had worked so hard to obtain would be lost in an instant. If his master knew about his true intentions, she would also find it repulsive.

Li Tong Guang instantly broke down and, unable to accept the reality, hurriedly fled. Ruyi told Yang Ying that to control someone, one must exploit their weaknesses. Suddenly, Ning Yuan Zhou embraced Ruyi, knowing that she had always been strong and was moved by her willingness to reveal her scars for their sake. He assured Ruyi that she would never be alone.

Jin Mei Niang secretly listened nearby and saw Yu Shi San. She gave a hint to Liuli."

On his way home, Li Tong Guang suddenly encountered an assassination attempt. However, the assailants were outnumbered, so Li Tong Guang sent out a signal for help. Ning Yuan Zhou led a group of people to rescue Li Tong Guang, while Ruyi secretly observed from behind. Due to the lack of an antidote and the enemy being armed, Ning Yuan Zhou's actions were hindered. Ruyi appeared masked, as Li Tong Guang believed that capturing the leader was the key to subduing the thieves, leading to a chaotic scene.

Ning Yuan Zhou's physical strength waned, and he was injured. Li Tong Guang recognized Ruyi as his master and in his deranged state, declared that his master belonged to him alone, and no one could take her away. Taking advantage of the confusion, Ruyi killed the leader of the assailants, causing the rest to flee in disarray.

When the members of the Liu Dao Tang arrived, Ning Yuan Zhou had already collapsed and couldn't hold on any longer. Ruyi, tearfully anxious, reluctantly informed Qian Zhao that Ning Yuan Zhou had been poisoned with an incurable toxin from the previous dynasty. Qian Zhao and the others were surprised that Ning Yuan Zhou had been afflicted with such a poison without an antidote. Ruyi explained that Zhang Song had poisoned Ning Yuan Zhou's tea to control him completely, and due to delays in their journey, they hadn't obtained the antidote in time, resulting in the onset of the poison.

Qian Zhao knew that this type of poison was unbearable once it took effect and wondered how Ning Yuan Zhou had managed to endure it. With no other options available, Ruyi cut her wrist to save Ning Yuan Zhou. Li Tong Guang failed to uncover the identities of the assassins, and although he wanted Ning Yuan Zhou dead, he was afraid that Ruyi would hate him.

Ruyi reluctantly bid farewell to Ning Yuan Zhou. She would rather try the antidote Li Tong Guang had obtained and test it on herself for the sake of Ning Yuan Zhou. Ruyi stayed by Ning Yuan Zhou's side, their clothes still entwined, and finally, Ning Yuan Zhou regained consciousness, bringing relief to Ruyi.
