The new version of Princess Huanzhu, the swallow lost Wei Zi, which episode is it?

In the 26th episode, Jinsuo goes to Yan Xi Palace to ask about Wei Zi's basic future. They also asked Father-in-law Pu about the identity of the cheating maid-in-waiting, but they didn't get an answer. The swallow decided that the queen had detained Wei Zi, so she questioned him, but the queen denied it. Yu Pei, which Erkang gave to Wei Zi, was discovered by the Queen during the execution. The "Four Guards" decided to visit Ren Jing Palace in the evening, and Erkang found Wei Zi as expected. During the fight, Saiwei advised them to openly invite important people the next day. Early in the morning, the swallow knelt down and asked the emperor to save Violet.
