What followed was a battle that lasted three days and nights.
The demon lords threw everything they had at Advent. Fire that could melt mountains. Ice that could freeze souls. Time manipulation that tried to age him to dust or rewind him to non-existence. Space magic that tried to tear him apart at the molecular level. Curses, blessings inverted, forbidden magic that mortals couldn't even comprehend.
Advent adapted to all of it.
The fire became his to command. The ice strengthened his cold resistance until he stood in absolute zero without flinching. Time manipulation taught him to exist outside temporal flow. Space magic gave him the ability to fold reality around himself.
One by one, the demon lords fell.
