He understood the reason for its changing expressions quite clearly.
It was simply worried about whether he, a mere Foundation Establishment cultivator, could protect their species—this concern was valid, and Song He did not feel annoyed or anything of the sort.
It wanted the assurance of the Xingke lineage, not just a promise from Song He alone.
He was well aware that he could not represent the Xingke lineage at this time.
He was very self-aware.
Moreover, for a Nascent Soul Spiritual Beast to lower its head to a Foundation Establishment cultivator over a trivial matter...it was already a rarity not seen in thousands of years.
There was nothing to be angry about.
Old Evildoer glanced at Song He, whose expression had not changed, and let out a chuckle, "However, even mortals pay with gold and silver for lodging. My tribe seeks your protection; we must offer you some benefits."
