Wei Zi's finger was punished.

The specific episodes are not clear, but I remember the content.

Probably Yaner took the blame for Cheng Yun and committed suicide in front of the Queen Mother and Kangxi. Kangxi was very angry because he was about to catch the evidence that Cheng Yun's father and daughter killed Yin Yin and Yizi, but Yaner's death made him punish Cheng Yun's father and daughter just because his horse died of the plague.

I hope it can help you, although I can't provide you with the specific number of episodes.
