Chapter 335: Eternal Frost Annihilation

"Congratulations on your successful advancement!"

David Jones curiously touched the new fur on Rainbow's back due to her advancement, feeling quite satisfied in his heart.

The only downside was that Rainbow's weight had increased a lot, and even now, in her miniaturized form, she weighed nearly a ton, which would be too heavy for an ordinary Trainer to carry.

"Yi?" (・◇・)?(Little sister, shall we have a battle later?)

Rainbow first twisted her slender body, slightly adjusting her comfortable position in the Trainer's arms, and enthusiastically shouted to Daphne.

The breakthrough from Class III to Class IV was a qualitative change for Rainbow; if she had not been confident in defeating the evolved younger sister before, now, feeling the immense power inside her, her confidence had returned.

"Mimi? Mimi!" (Battle? I can't beat big sister!)

Daphne shook her head and decisively admitted her weakness.
