She works as an animal trainer overseas and only comes back when the organization is in trouble. She tells some funny zoo stories to distract Que Cha. It works. Que Cha dries her tears. She asks Yu Rong to teach her how to tame beasts. She wants to be useful.
Secrets in the Basement
Xing Shen is handling a precious tripod vessel. He puts it back in its place and notices something odd. There is a mechanism for a secret compartment. He reaches for it. Yu Rong walks in right at that second. She interrupts him. She wants to see the "Grasshopper" he keeps talking about.
They go to the cage. The Di Xiao is massive. But it freezes up when it sees Yu Rong. It is terrified of her. She hides so she doesn't spook it further. Xing Shen talks about how he caught it. He and Ma Hanzi were just trying to have a barbecue in the woods one night. They stumbled upon the creature and dragged it home.

Fourth Sister is stalking them.

Xing Shen takes Yu Rong to see Master Sun. It is a grim sight. The man has fully turned into a beast. Yu Rong takes one look. She says there is no saving him. He cannot be tamed. Xing Shen is stubborn. He insists she try anyway.
The Blood Sac Theory
Uncle Changxi makes beef dumplings. Nie Jiuluo loves them. She and Yan Tuo plan to bring some to Sister Lu. The food gets them thinking. They compare humans and Di Xiao. They wonder about the transformation process.
Yan Tuo brings up a file he found in Lin Xirou’s hidden stash. It was about a girl named Xu Annie. The file suggests Di Xiao never live alone. They connect this to Lin Xirou’s behavior. She is constantly pushing Lin Ling to get married and have kids. Nie Jiuluo has a dark realization. She suspects they use blood relatives to reproduce. She calls it the blood sac theory.
