Ning Xiurui and Li Ji kept the two sisters, but they were rejected at the same time, so the master and disciples were depressed. The old sea doctor who had been imprisoned in the Dragon Palace pretended to be dead and escaped from the prison when the guards were not prepared. Ning Xiuren was worried that the truth about the death of the Dragon King would be exposed and decided to speed up and get rid of Ning Xiurui. Tang Linlin was humiliated by her in-laws during a blind date, and the two sisters publicly pointed out that each other was old and disrespectful. Ning Xiurui secretly guarded Su Yinyin all the way, and the two finally met again outside the Great Wall. The old sea doctor found Ning Xiurui and told the news of Ning Xiuren’s conspiracy and the death of the old dragon king. In order to prevent Ning Xiuren from committing evil deeds again, Ning Xiurui asked the emperor for permission to supervise the case of the evil dragon stealing the heart.
