The Angels would either not retreat from the Paradise world, or if they truly choose to retreat from that world, they might choose a world more suitable for their survival. Finally, if there's a possibility of counterattacking the Paradise world, even if those Angels decide to retreat, they will certainly choose a powerful world as much as possible.
Even if there are conditions, as long as any faction gives a strong guarantee, it's possible that those Angels might directly retreat to the Divine Realm. After all, although the threat of the Light God King can make ninety-nine percent of the factions dare not accept those Angels, the Light God King is ultimately a Divine King and not a Divine Emperor. If any top Divine King truly wants to obtain those Angels, the deterrence of the Light God King might not be enough to scare them away.
