This nearly forgotten Little Butterfly, with just a gentle flap of its wings, triggered a massive upheaval.
Of course, this upheaval was beyond the Mysterious World, and Ling Xiao definitely could not sense it.
What he could sense was merely the peculiar aura emitted from within Little Butterfly, which unexpectedly elevated his cultivation level by a rank.
Twenty percent strength of a Half-step Celestial!
Could advancement really be so effortless?
Ling Xiao couldn't help but reveal a shocked expression, it seemed that this Little Butterfly had some special connection with the Mountain and River Martial Soul.
And it was definitely not something ordinary.
The enhancement brought about by the gentle flap of its wings was almost on par with the spirit liquid Ling Xiao had created using tens of millions of Low-grade Spirit Stones, simply defying the heavens.
"You actually advanced?"
The Moon Lady too was somewhat surprised.
