"Boom!"
The explosion, comparable to the Magic Guided Missile from before, blasted forth, proving the Son of Heaven's defenses futile as his entire being was obliterated in the blast.
Simultaneously, the sphere of light continued to spread at high speed, engulfing nearly a kilometer radius around it, even the Blood Emperor, who attempted to flee to the other side, couldn't escape the explosion's range and was instantly overtaken and devoured by the sphere of light.
In an instant, every creature within the sphere of light's range was reduced to ashes in the explosion.
Several seconds later, the white light dissipated.
At the locations where the Blood Emperor and the Son of Heaven had perished, there floated a Fire-red Feather and a battered cross, respectively.
For people of their status, it was, of course, standard to have resurrection items on hand. However, even among resurrection items, there was a shared cooldown period.
