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?”
