Chu Chen looked at Nirvana with some anxiety and said gravely, "Nirvana, this evolution's pain far exceeds the past, but it will grant you even greater power. Are you willing?"
The man and the creature were in sync, and Nirvana naturally understood the meaning in Chu Chen's words.
Among the five Guardian Beasts, Chu Chen's desire for power was much stronger than that of the other four Guardian Beasts.
After all, it had once been abandoned by its previous master due to its lack of strength.
Even though the grudge had been avenged, its deep desire for power had never diminished in the slightest.
When Nirvana heard it would gain stronger power, it did not hesitate for a moment, letting out anxious "chirp chirp" sounds.
Chu Chen sighed when he saw this, patted its head, and said solemnly, "Since you have decided, I will fulfill your wish." With that, he fed the undead crystal to Nirvana and then poured in the Evolution Potion.
