Episode 37 recap: Li Yi cured Cui Yi.

Cui Lin felt that just because Li Yi doesn't kneel now doesn't mean he won't kneel in the future. They argued over a sketchbook, and Cui Lin told him that she had worked hard to draw it and asked him to return it to her. They playfully teased each other, and Li Yi passionately kissed Cui Lin.

A soldier from the Cui family army delivered a letter to Cui Lin, but when she opened it, numerous hidden needles came out. Li Yi brought Cui Yi in front of Mu Xian He, who performed a magic trick, and Cui Yi saw his deceased wife, He Min.

Cui Yi looked at He Min and said he never expected to see her again. He cried and said they were finally reunited. He asked He Min if she blamed him, blamed him for not coming back in time for her. He Min didn't speak, so Cui Yi blamed himself and regretted not being able to save her. As Cui Yi was about to touch He Min's face, someone suddenly attacked them from behind.

Cui Yi drove away the attackers with a sword, and he also woke up from Mu Xian He's trick. He asked Mu Xian He who he was and why he brought him here. Mu Xian He asked Li Yi and the others to come over. Cui Yi saw that Li Yi recognized him, and Li Yi and General Xiao Pei happily said that Cui Yi was finally better.

Cui Lin was extremely happy to see Cui Yi clear-headed, but she felt a bit sad when she saw that all of Cui Yi's hair had turned white. Cui Lin asked Li Yi why he didn't tell her earlier, and Li Yi told her that the physician said the method was risky, and he didn't know how to face Cui Lin if something went wrong.

Cui Lin was very grateful to Li Yi and told him that she had something important to tell him. She felt that Liu Cheng Feng's death was suspicious. A few days ago, she saw Wu Luo's cousin arrive in Xi Chang Jing, and she had been monitoring him for some time. Li Yi told her not to worry and that he would handle it.

Prime Minister Gu personally came to see Wu Luo. Previously, he had always sent messages through Liu Cheng Feng, but now he no longer trusted him. He told Wu Luo's people that as long as they helped him kill the Crown Princess Cui Lin, he would fulfill their desire for territory. Wu Luo didn't understand why Prime Minister Gu would do this, and Prime Minister Gu told him that the current Emperor was a confused ruler, and he didn't want to entrust himself and his daughter to such a ruler.

Wu Luo agreed to the alliance invitation from Prime Minister Gu, who told him that Liu Cheng Feng had always admired Cui Lin and warned them to be on guard against him. Wu Luo informed Prime Minister Gu that Liu Cheng Feng wanted to abduct Cui Lin, so they should devise a plan to bring Cui Lin out and kill her.

Liu Cheng Feng asked Ashu to change his surname to Liu to make them family, and Ashu immediately knelt down to express gratitude for the bestowed surname. From then on, he would be called Liu Shu. Li Yi suggested to Cui Lin that Cui Yi should live in Qingyun Temple, where the environment was good, and he could also teach Xuan Ze there.

Cui Lin thought it was a great idea, and she believed Cui Yi would be very happy there. The Emperor learned that Jie Shuo had come to Yingzhou to cause trouble again and wanted Li Yi to lead troops to resolve the situation. Pei Xian thought it was too dangerous for Li Yi as the Crown Prince and volunteered to go himself. Prime Minister Gu suggested that Pei Xian's son, Pei Yuan, should also accompany them.

Cui Yi arrived at Qingyun Temple, and Li Xuan Ze said he finally met Cui Yi. He had heard a lot about Cui Yi. Cui Yi asked who told him those things, and Li Xuan Ze said it was General Han who informed him. Cui Lin watched Cui Yi and Li Xuan Ze getting along well, so she left with Li Yi at ease.

To express their gratitude to Mu Xian He, Cui Lin and Li Yi invited him to have a meal at Fengying Tower. Mu Xian He mentioned that he wanted to eat caviar, and Cui Lin promised to get it for him. Mu Xian He then told Cui Lin that he would perform a magic trick for her. He conjured many fireflies for Cui Lin and Li Yi to enjoy while holding hands. Mu Xian He congratulated them on their wedding using this magic trick.

Li Yi and Cui Lin were having hotpot together, and Li Yi wanted to capture this scene in a painting. However, Cui Lin refused, and they started to argue over the sketchbook. Cui Lin had drawn a scene where Li Yi was kneeling on the ground, but Li Yi felt that it hadn't happened and didn't want it in the painting, as their future child might find it amusing.

Cui Lin explained that she was being prepared for the future, but Li Yi wanted to tear it off. Cui Lin insisted that she had worked hard on it and couldn't tear it off. Cui Lin and Tao Zi went to Fengying Tower and met Vice General Tan, who handed a box to Cui Lin. Just as Cui Lin was about to open it, numerous needles flew out from inside.
