It only takes less than a second for Archangel Raphael to kill all these people, including the prestigious ten ancestors, with his own hands!
The people didn't have time to scream out of pain, and all of them instantly turned into ashes and disappeared without a trace.
Just a slightly bigger pressure pressing down on these people and a hotter holy light hit the ancestors...
And the mighty ancestors all died without knowing why they died.
They just listened to the nice voice in their minds, asking them to approach their archangel without doing anything bad to the archangel.
They just crossed the 'line' between the two parties and got slightly closer than their previous distance, but they were killed without mercy.
The twenty people would never know why they died even after they returned to their original world.
