Aditya was almost done with the undead from the 11th Wave. When the number of undead significantly decreased, he noticed something unusual or out of place in one of the corners. The red magic circle, which he assumed disappeared after summoning the undead every time, did not really vanish into thin air.
The Red magic circle shrank in size and power and stayed in some corner. Because he was facing undead in huge quantities from all directions, he did not have a moment to spot the magic circle in any of the corners.
When he almost overlooked the magic circle, his eyes were scanning for the location of the remaining undead. He noticed that behind a small cluster of undead, in the corner, there was the red magic circle. But right now, the magic circle wasn't glowing as brightly as it did before.
At first, he did not understand what was special about this magic circle. He only assumed that the soul role of this magic circle was to summon undead at the command of the summoner.
