Reeling from his injuries and past losses, Xie Huai'an awakens and sets a trap to confront Liu Ziyan as Chang'an's stability teeters.
Hiding his kinship with Bai Guan, Xie Huai'an helps her leave safely and secretly orders the execution of their enemy, shouldering the feud alone.

As Chang'an falls into chaos, Qing Yi escapes while Xiao Wenjing protects the injured Xiao Wuyang, and Xie Huai'an lies hidden as Wang Pu draws near.

To derail Yan Fengshan's negotiations, Xie Huai'an sends Wu Mei across enemy lines and coordinates with Gu Yu to pressure the merchant Yang Chuhao.
