What episode is the outing of Swallow and Kangxi?

Yongqi, Erkang and Ertai, on the one hand, are worried that Gan Long will bring Wei Zi into the harem, on the other hand, they are also worried that the fact that the swallow deceives the king will lead to fatal disaster. On the way out, this group of people tried their best to make Swallow and Wei Zi happy, hoping to get Gan Long's promise of "Amnesty" from them, and then told Wei Zi that Wei Zi was the real princess who returned to Pearl, so that they could all go back to their places. However, the swallow turned it over three times and twice, but it failed to do enough to undermine everyone's plan to please Qianlong. Thanks to Wei Zi's quick response, the situation turned around. Everyone has a good side, which makes Gan Long happy for the Swallow's treasure hunt, and makes Wei Zi's intelligence come into play, which makes Gan Long sit up and take notice of him. It is said that a group of people arrived in a town, and a large family in the town was holding hydrangeas to get married, which was very lively. Everyone is curious to look forward. Naughty little swallow, seeing the beautiful girl who is about to get married and the hydrangea that so many people want to grab, jumped up at the moment, grabbed the hydrangea and threw it at Yongqi. Yongqi was surprised and returned the hydrangea to the swallow. Two people come and go, one of them is eccentric, and hydrangea goes straight to a begging teenager next to the crowd.
