The blood clan's kings and queens could become the mediums for the demon lords and by then, they would also be equal to the three kings who had the archangels' consciousness and strength in their bodies.
Time was ticking, and Atherton didn't need too many solemn ceremonies to summon the demon lords, unlike what the Queen did.
Thus, Atherton simply slashed his palm and manipulated his blood to create one huge magic circle in the sky above everyone else.
He didn't even bother to hide his movement because the archangels could enter the battlefield anytime, so why bother hiding this summoning process?
The blood magic circle was completed within seconds, not as long as the Queen's magic circle that required several minutes to be completed.
After the magic circle was ready, Atherton didn't hesitate to open his mouth and touched his four vampire fangs one by one.
