Shadowslash suddenly shivers, his expression changes, he knows that his instinct was warning him about something, without any doubt, he was being watched but he doesn't know who it is.
He frowns but quickly, his expression becomes peaceful, he is confident with the power of his soul, someone capable of bypassing his divine sense only means two things, first, they are powerful enough to overcome his divine sense or they have the ability to transcend the void just like him and Banjo.
Either way, since he does not sense malice from his killing star, the person that is watching him doesn't hold any ill intention towards him, unfortunately, this is going to slow down his preparations.
He cannot let anyone, other than his family, find out what he is currently doing, he gave some encouraging words to the elites of the Spirit Fox Clan, praising them for their growth, he then left rather calmly.
