After the death of his adversary, his immortal soldiers were returned to the empty void of nothingness thus he returned and the magic outburst which he had experienced in the battle gave birth to constellations within his mana circles which could house inner galaxies with a certain power for each.
The first constellation housed light energy which it's photons carried mass ,which was deemed impossible by theorists and scientists themselves, and yet this young academy student figured out the impossible itself and gave it an understanding form from within, thus the photon ring was created which allowed the user to emit a strong photon beam strong enough to pierce a small forming black hole in theory.
The Imperial family had heard what happened and about the one responsible for taking down the opponent who brought destruction upon these lands and was rather shocked by the news that it was an academy student who took down this threat level opponent and his ghastly army, thus he invited his vassals and senate for the congratulations to be given to this student and a title plus land for him to rule.
Not all we're pleased about the Imperial order by his majesty but none disobeyed expect the kings younger brother Duke Luis of the 3 swordsman families who had almost equal strength and influence as the royal family .
