After Little Taotie left the Imperial Palace, she didn't just leave the Mortal Realm without a care. Instead, she observed for a while, and once she was sure the 'son' she had chosen could bear great responsibilities, only then did she leave with Feng Qi.
On that very day, Feng Qi, who was the Empress Dowager, passed away in a manner resembling a feigned death.
The Third Prince thought the Retired Emperor would return once the Empress Dowager passed, but even after she was laid to rest in the Imperial Mausoleum, the Retired Emperor did not appear.
When Little Taotie and Feng Qi returned, they saw the War God standing in front of the castle, looking as if he knew they would return today and had been waiting a long time.
Little Taotie transformed back into her form as the Little Beast Bai Bai and ran towards the War God.
