Two ghosts from Gaoujun's past continue to haunt him, as Shouxue and the eunuch Wei Qing investigate the cause. The answer may lie in the depths of the red-light district...

Yi Siha, a eunuch serving Feiyan Palace, visits Ye Ming Palace. He has seen the ghost of a boy holding a blue swallow feather and asks Shouxue to help him. During her investigation, Shouxue comes across Yi Siha being caned by some older eunuchs. When she stops the punishment, Yi Siha's mentor Kang Lan trembles with fear. In Shouxue's eyes he saw a horrifying monster.

Xue Yuyong warns Shouxue against getting too close to Gaojun, and Shouxue sends Wen Ying to Quechao Palace to investigate the Magpie Consort.

After confronting the Magpie Consort, Shouxue and Gaojun discover the shocking reason behind the mysterious events. Shouxue then learns of her relationship to the Owl through Niao Lian.
