"Yes, I could not sense it, But I am sure it is because of this spiritual power turbulence here."
Parashurama was taken aback by the questioning of Durvasa but come to realisation that what he said match the description that is happening with him, He quickly answered.
He still believe the disruption in the spiritual power here that is why he can't sense his Parshu, That can be the only explanation there can be, There is no other way to break his connection from his axe.
Yes there is no way his connection with his axe can be broken, As long as that axe exists in this time and space, No matter where it is, That is still connected to him.
And the moment he would recall the axe it would come back to obeying the order of its master, which means he is the sage warrior of the Bhargava clan.
It's just he can't wrap his mind around where the axe could have gone. The blast did not happen and so the axe should be around somewhere but he can't see it.
