You can say that it was a really unimaginable thing that the statue would glow like this. But then suddenly something more unexpected happened because not long after that some oni humans present in that room begin to glow.
All this time, Sam was using his spiritual vision to look at the statue, but other than the spiritual energy that the statue was releasing he did not notice anything strange. Right now when he looks toward those people who are also glowing, he becomes surprised.
Sam could see the spiritual energy of those people begin to increase rapidly. Even though he did not know what will happen after they receive the blessing, most likely everyone will break through and all get very close to breaking through.
'How the hell is the Spiritual energy going inside of them like that?'
