Unexpectedly, this golden eagle was actually willing to incubate an egg, and it wasn't even its own offspring. In the subconscious of male beastmen, this was considered a humiliating act, a blow to their pride.
Not to mention, this golden eagle was not only powerful but also appeared extremely proud. The extent to which he was willing to do this just to see a female was a clear indication of... his affection for this female.
Thinking of this, Gu Di’er's eyes grew colder, with a hint of malice lurking.
If this eagle had just refused his request, regardless of whether An Yao really knew the eagle or not, he could have silently found an explanation he could believe in to absolve her unconditionally. But this eagle beast had actually agreed without hesitation.
Then he could basically conclude that this eagle beast definitely knew her, and their relationship was unusual. As for how far things had progressed... Gu Di’er didn't dare to think about it, nor did he want to.
