Title: Dusty Memories of You (Hard to Remember You)
In the cave, Luolan shows chicken Bai a special bell (her fabao) and asks if he remembers it. He does not. She then curses Tushan for allegedly backstabbing her, but admits that she has hazy memories of her past too.
She reveals that long ago she made a Heart Oath with a former incarnation of Bai Yuechu in front of the Tushan sisters at the Kuqing Tree. However, it seems that the pledge did not work. So Luolan suspects that Tushan on the surface agreed to Luolan's request but secretly nullified it without her knowing as they want Dongfang Yuechu to marry Honghong instead.
Susu and others (who somehow got into the cave) overhear in shock, and Susu calls Luolan a 'mistress' (小三). They laugh at how Dongfang Yuechu dumped Luolan. But Luolan said her lover was not Dongfang Yuechu, but Pingqiu Yuechu. Nobody not even Qingtong have heard of Pingqiu Yuechu though.
Luolan then asks how they got into the cave. Venom Grandpa was playing his guqin to cast Sonic Venom (音波毒功) that slowed down the reflexes and weakened the spirit energy of others that heard it. So Susu used her Invincible Claws to cover Wang's ears so that he could move at normal speed and defeat Venom Grandpa and Venom Granny.
Wang Fugui uses his Wangquan Will Blade to free chicken Bai from Luolan, but is blocked by a shield from the Three Royal Shields. They lent it to Luolan's frog assistant because being royal guards they would not let Luolan die. However the shield cracks, so he continuously uses the Wangquan Blade to break the shield. Chicken Bai then walks over to Susu, who rubs her cheek against Bai's, saying she missed him so much.
