The new princess Zhu Huan, the swallow and others turned against the emperor. Which episode was the maid-in-waiting?

The new princesses Zhu Yan, Sunny and Benmingjie did not return to the palace, while Wei Zi, Erkang and Yongqi went back, but Yongqi also returned to Dali to look for swallows in the last episode. Episode 94 (Episode 20 of Where Are People Going) Yongqi wrote 730 letters and asked the swallows to open one every day. When the two teams broke up, the swallow refused to appear, hiding from crying and sending everyone away. Suddenly, she rode to the top of the mountain and looked at the distant chariots and horses. Liu Hong, who was marching, suddenly heard the call behind him. It is a smart flying horse, and the two go hand in hand. When the emperor and others returned to the palace, the Queen Mother said that she wanted to establish Wei Zi's birthright and get married as soon as possible. Yongqi wants to leave a child for Princess Kuaiyi, but the thought of swallows can't be realized. He came to Shufangzhai to see things and think about people, and took the swallow clock and balloon back to Yonghe Palace. Episode 98 (Episode 24 finale of "Where Are the Children Going") Yongqi thinks that the task is half finished and the children will be his hope for his mother. Ben Ming Jie woke up and drew a picture of a swallow sleeping in a bed. When Xinrong gave birth to her son, Yongqi said goodbye to the emperor. The emperor respected his choice and declared him dead if he didn't return for three years. Yongqi rode out of the palace alone with a newly written letter and a swallow bell when the child was full moon. Er Kang and Wei Zi, who are pregnant, saw each other off halfway. Swallow and Yongqi finally met again one day after the agreed deadline. Ben Ming Jie said goodbye to Xiao Jian and rode away.
