Which episode is Sansheng Sanshen Pillow Book Sansheng Stone can't write the name?

The book on the pillow of Sansheng III was broken in episode 52.

In order to carve Donghua's name on Sansheng Stone, Jiu Feng cut off its tail. The Qingqiu fox family can condense their obsession into a musical instrument every time they cut off their tails.

Breaking the tail once is like experiencing life and death. Unfortunately, what she understands is not to end this doomed love, but to persist for longer.

The emperor embraced Jiu Feng and looked at the beautiful and delicate girl in front of him with deep affection. Bai thought he was dreaming in a daze, and even regarded this scene as a human robbery. She murmured that she would never let the emperor carry himself in the rain again.
