Bai Fengjiu, the imperial concubine of Qingqiu, was saved by Emperor Donghua and she remembered it in her heart. To repay her gratitude, Fengjiu worked as a maid in Taichen Palace for many years. Later, Donghua was locked in the Ten Evil Lotus Realm, and Fengjiu transformed into a fox to save Donghua. Since then, Fengjiu has been accompanying Donghua as a fox. When she learned that Donghua was going to marry Ji Heng as the empress, Fengjiu left sadly. Later, Donghua went to the mortal world to experience tribulations, and Fengjiu followed him. In the Fanyin Valley, Fengjiu fell into Alanruo's dream to get the Pinbo fruit, and relived the past of Alanruo and Chen Ye. Donghua transformed into Xize to rescue Fengjiu. In the battle with Miaoluo, justice defeated evil, light defeated darkness, and finally Donghua and Fengjiu became a couple.
