"What other ways are there to obtain a spot in the Energy Pool?" Billet asked casually, more out of boredom.
"Sorry, I'm not entirely sure," the staff member responded respectfully. "The method changes every year."
Billet took a small sip of the coffee that had just been served and remarked,
"I heard that your Energy Pool doesn't allow King-level Pet Beasts to enter?"
The staff member replied warmly, "That was last year's rule. This year, the Energy Pool's reserves are sufficient, and King-level Pet Beasts can absorb enough energy to advance by a small stage."
A "small stage" refers to advancing from the early stages to the mid stages, or from the mid stages to the late stages.
Allowing King-level Pet Beasts to advance by a small stage without side effects indicated that this year's Energy Pool had significantly higher energy reserves compared to the previous year.
