The Scent Seeking Butterfly had virtually no combat abilities, so staying close to Blux and Ethen was considerably safer.
Soul Stones are extremely rare, but Mila had once had the fortune of seeing a small piece at an auction.
Accompanying Mila to this auction was the Scent Seeking Butterfly, which had thus encountered the scent of a Soul Stone before.
Relying on the scent from memory, the Scent Seeking Butterfly diligently sniffed the air, trying to discern the trail of a Soul Stone among all the passing aromas.
With the Scent Seeking Butterfly as a guide, the chances of success for Ethen's mission were significantly increased. All he and Blux had to do was closely follow the Scent Seeking Butterfly to protect it.
As they reached the halfway point up the mountain, the Scent Seeking Butterfly suddenly increased the frequency of its wing flutters.
It was clearly excited. Mila, who had a soul connection with the Scent Seeking Butterfly, immediately received its feedback.
