Shouxue searches the storehouse for the ghost's gemstone, while Gaojun investigates the Raven Consort's secrets.

Shouxue must solve the mystery of the ghost that appears beneath the willow tree, and the two ghosts that appear in the emperor's chambers.

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.
