A cold chill was sent down Zhong Yue, Shi Buyi and the others' spines; they were not from the Prison Realm or even native to this place. But they've deceived all the others to thought they were born here, allowed them to take part in this event; yet Bi and An saw right through their identity which none of the other gods managed to do so!
If Bi and An exposed Zhong Yue and his companions, they would be in deep trouble!
The Ancestral Star was located somewhere in the Solar System that was sealed by some kind of unknown power and that person who casted this seal must be someone incredibly powerful.
And if the news of Zhong Yue and the others were from the Ancestral Star was spread out, the outcome would be very worrying!
These two are not demon gods yet, they shouldn't be that strong by now, which means that they are just trying to trick us into telling them our information.
