Su Yinyin no longer stubbornly kept Ning Xiurui by her side, and wanted to leave Shengjing, letting Ning Xiurui let go without any hindrance. Su's father also agreed to her daughter's departure from Beijing, and persuaded her to use time to dilute everything. Su Yinyin guessed that Su's father also knew Ning Xiurui's identity, and Su's father immediately avoided it.
In Ning Mansion, Li Ji anxiously told Ning Xiurui that Su Yinyin and Tang Linlin were going back outside the Great Wall and asked Ning Xiurui to find a way to dissuade them. Ning Xiurui immediately went to Su Mansion to look for Su Yinyin, pretending that Su Yinyin could not protect Su Yinyin from outside the Great Wall, so he could retain Su Yinyin. Su Yinyin said indifferently that his danger was brought by Ning Xiurui and Ni Lin, and that Ning Xiurui was the biggest danger by his side. Ning Xiurui's rejection of Su Yinyin was not quite right today, and let Su Yinyin talk about it another day. Su Yinyin called to Ning Xiurui, confessing that entering the palace that day was to ask the emperor to marry him, saying that he was too attached to Ning Xiurui, and now it is important to save his life. Ning Xiurui also wanted to accompany Su Yinyin for a few days. Su Yinyin directly drew a clear line with Ning Xiurui and shut Ning Xiurui outside, but tears could not help but keep falling.
Li Ji heard that Tang Linlin was leaving Beijing now, riding her horse to stop Tang Linlin's motorcade, wanting to keep Tang Linlin, or to travel the world with Tang Linlin. Tang Linlin told Li Qi not to mess around, saying that there was something urgent outside the Great Wall to deal with, and ordered Li Qi not to follow her with friendship. Li Qi could only watch Tang Linlin leave aggrievedly. Tang Linlin felt warm when she saw someone miss her.
Ning Xiurui and Li Ji's apprentices and apprentices were in the courtyard to soothe their sorrows, like a broken relationship. Ning Xiurui helped Li Ji analyze the probability of Tang Linlin becoming a princess. Li Ji felt that her mother was still alive and she would definitely support herself. Li Ji also talked about the good relationship between his mother and Mrs. Su. When he was a child, he pointed out Su Yinyin as a concubine. Before Li Ji finished speaking, he noticed a thunderbolt on the blue sky. Seeing Ning Xiurui's sharp eyes, he immediately changed his words and said that he put it on hold after his mother died. Li Ji also felt that the human world is so embarrassing, and it's good to just stay with Master like this.
The old sea doctor pretended to convulsions, killed the soldiers, and escaped from the Dragon Palace. Ning Xiuren learned that the old sea doctor had absconded to the sea to inform Ning Xiurui, and immediately made a decision between Ning Xiurui and Ni Lin. He wanted the dragon people to completely lose trust in Ning Xiurui, and ordered Ning Mo to urge him not to accelerate speed.
Outside the Great Wall, Tang Linlin wanted to be Mrs. Yushi's daughter-in-law, and humblely offered tea to Mrs. Yushi. Tang Linlin flashed Li Ji's mind and accidentally knocked over the tea cup. Mrs. Yushi scolded Tang Linlin harshly for her lack of education, and incidentally scolded Tang Linlin's parents all over. Su Yinyin couldn't see Tang Linlin being wronged, and pulled Tang Linlin out of the camp.
Usul is jealous of Su Yinyin's title of No. 1 in Shengjing, and wants to compete with Su Yinyin. Although Su Yinyin doesn't know how to ride a horse, she loves to come down. Su Yinyin changed into a horse outfit and Ursul horse racing. Tang Linlin nervously taught Su Yinyin to grab the reins. Su Yinyin staggered forward, panicking, Ning Xiurui was in the dark, casting a spell to stabilize Su Yinyin and helping her win Ursul. Ursul refused to admit defeat and agreed to try again next time. Su Yinyin didn't know how he won, and proudly accepted it.
The old sea doctor found the Second Highness, and told Ning Xiurui that his hand was burned by Nilin, guessing that his highness was burned while snatching Nilin. Ning Xiurui couldn't understand why his brother didn't harm himself in the first place. The old sea doctor told Ning Xiurui that it was the old dragon king who blocked the sea in order to keep Ning Xiurui, and people in the sea could not go out. But the old dragon king passed away shortly after sealing off the sea, and the old sea doctor guessed that this was also the work of the great highness. Ning Xiurui was in deep pain. He did not expect that his father had passed away, and he did not expect that his father was not willing to forgive himself, but to save himself. Ning Xiurui knelt on the ground and wept bitterly. He did not expect that the home he had always wanted to return to and his father were gone at the same time. Ning Xiurui helped the old dragon king erect a tombstone on the beach to show respect. The old sea doctor is pleased that Ning Xiurui can understand the heart of the old dragon king. Ning Xiurui knelt before his father's grave, vowing that no one would be hurt by Ni Lin again.
Ning Xiurui went into the palace to meet the emperor, and asked the emperor to hand over the evil dragon's heart-stealing case to himself. The emperor doubted Ning Xiurui's identity as a dragon, and Ning Xiurui proved his innocence with the friendship between his master and apprentice for 30 years. Only then did the emperor believe that Ning Xiurui was innocent, and handed the case to Ning Xiurui. Ning Xiurui asked about Su Yinyin's marriage and wanted to know which son it was. The emperor said that Su Yinyin's marriage partner was the teacher, and Ning Xiurui showed a smile.
