Inside the Phantom Beast Breeding House,
“Sir, which one do you want to buy?” the waitress asked weakly.
Chen Qiyue pointed to one of the phantom beast eggs, “I want it!”
“Okay, I’ll take it off for you.”
“Wait! I choose this one!”
Chen Qiyue pointed to another egg.
“Okay, do you want to change it?”
“hold on!”
Receptionist: …
half an hour later,
Chen Qiyue happily embraced the black-and-white Laqiu in his arms, and left with the blue-spotted egg.
The female receptionist suddenly turned pale, her legs became weak, she fell to the ground, and began to cry.

Chen Qiyue spread his hands, who made my golden finger have to be like this…
Heck, I’m a decent person!
