The sensing between royal bloodlines is quite accurate.
And the Elf Royal Clan's bloodline, in addition to enhancing its own spell abilities and natural affinity, has another vital function.
That is to sense the emotions within others' hearts.
Of course, this sensation is only applicable to common people. For Transcendents whose power is not inferior to their own, this ability is much weaker.
Even with Adam's current strength, he can't perceive Isius's emotions, he can only vaguely feel some of them.
But the elf mother and daughter before him are different.
They not only possess the Elfish bloodline, but their power is also weaker than Adam's.
So in front of Adam, it's hard for them to hide their emotions.
Perhaps some profound things are hard to discern, but some simple ones are quite easy.
This is why Adam could discover them.
Of course, it's also closely related to them having no intent to conceal themselves.
