The situation at the academy grew chaotic due to the numerous spells unleashed by the attackers. Nathaniel led the academy's sorcerer teachers in fighting back and defending the premises.
"Hold this position, buy time for the children to escape!" Nathaniel said firmly as he descended onto the battlefield.
With determination, Nathaniel guided the sorcerer teachers in their efforts to defend the academy against the escalating attacks.
Upon reaching the attackers' position, Nathaniel and the sorcerer teachers immediately engaged in combat with unwavering resolve to protect the academy.
The resistance began with courage and skill as the sorcerer teachers, under Nathaniel's leadership, launched counterattacks using powerful and targeted spells.
One of the academy sorcerers, endowed with the power of fire, unleashed their magic to attack the enemy.
"No one can escape my assault! Inferno Whip!" exclaimed the sorcerer as they created a spinning whip of fire to confront the assailants.
Meanwhile, a sorcerer skilled in controlling the wind also took action.
"Control the wind, strike my enemies! Cyclone Strike!" shouted the sorcerer as they conjured a whirlwind enveloping their opponents.
Elsewhere, a female sorcerer with the power of light also joined the battle.
"Let my bravery guide this path! Sacred Radiance!" declared the woman with unwavering determination. Holy light emanated from her body, forming a protective circle that shielded the academy sorcerers from enemy attacks.
However, the enemy onslaught grew more ferocious, and the academy sorcerers fought to survive with all their might. Spells darted through the air, creating colorful flashes and ground-shaking explosions. The sorcerers moved swiftly, evading attacks and responding with unwavering determination.
Suddenly, a resonating voice from the attackers echoed throughout the academy. A sorcerer clad in black robes, with a face filled with hatred and malicious intent, began chanting a magical incantation that sent shivers through the air.
"In the darkness of the night, I summon the power of chaos! Eterna Maledictio!" exclaimed the sorcerer in a hoarse voice, swinging their magic wand towards the sky.
Dark energy radiated from their wand, merging with the looming clouds in the sky. Slowly, the energy formed a threatening and enigmatic symbol. The ground trembled, emitting a chilling sound that haunted the soul.
Suddenly, the dark energy exploded into thousands of black stars floating in the air. Each star possessed a terrifying evil power. They swiftly moved towards the academy sorcerers.
Nathaniel, witnessing the sight, was taken aback. "Damn, that's a level 8 dark spell. Do they truly seek to annihilate us? Skilled healing sorcerers, quickly heal our comrades!" exclaimed Nathaniel, instructing the healers to provide assistance.
The light sorcerers, gifted in healing abilities, began chanting their spells.
"In the healing light that brings restoration, replenish drained strength! Healing Aura!" they called out with deep concern. Healing light emanated from their hands, enveloping the wounded sorcerers and granting them renewed strength.
Seeing that the evil power overwhelmed some of the academy sorcerers, Nathaniel quickly gave an order.
"Sorcerers who can chant protective spells, gather and create a defense!" he commanded.
Upon hearing Nathaniel's order, several sorcerers with protective abilities from the academy gathered in the midst of the battle. They swung their magic wands and began chanting protective spells with utmost concentration.
The light sorcerers skilled in defensive magic also utilized their powers.
"In eternal protection, shield us from the forces of darkness! Barrier of Light!" exclaimed one sorcerer with defensive abilities. A shield of light enveloped the academy sorcerers, deflecting the attacks of the black stars in all directions.
"In the blazing fire, become a glowing shield! Infernal Firewall!" shouted a sorcerer with fire abilities, creating a blazing wall of fire that formed a barricade protecting them from the threat of the black stars.
The evil sorcerer, witnessing their attack being thwarted by the academy sorcerers, felt somewhat surprised. Then they said, "Interesting, it seems that the protective magic created by a combination of rank 5 and 6 sorcerers can withstand a rank 8 spell. Perhaps this time I'll be a little more serious."
With a growing malevolent intent, they uttered a new chant with a hoarse voice echoing across the battlefield.
"In the darkness that surpasses everything, in the infinite abyss, I invoke uncontrollable power. With a tormented soul and burning vengeance, I summon destruction from the depths of my hidden heart. Oh, terrifying power that annihilates everything, come forth and strengthen my will shrouded in darkness. Abyssal Annihilation!" they exclaimed with deep hatred.
The sound of their wicked chant resonated in the air, and dark energy began to gather in the sorcerer's hand. The energy grew larger and darker, creating a chilling atmosphere around them.
The academy sorcerers who witnessed the scene panicked and tried to evade, but they realized they couldn't completely avoid the impending attack. They exchanged worried glances, aware of the immense power that was about to be unleashed.
Seeing that the academy sorcerers were unable to withstand the spell, Nathaniel finally strengthened his resolve.
Nathaniel began reciting a chant.
"On the journey to the pinnacle of magic, I have sacrificed everything, and this time I will sacrifice again," Nathaniel stated firmly.
The academy teachers and sorcerers who heard him panicked and tried to stop him.
"Nathaniel, there's no need to go too far!" exclaimed one of the academy sorcerers.
"Nathaniel, there's no need to unleash that spell!" shouted a teacher who was also fighting.
However, Nathaniel did not retreat. He continued the chant resolutely.
"I come to you, my heart burning with fire. Accept this sacrifice and destroy the evil power," he uttered.
"In the darkness that engulfs everything, where fire and light converge, arises an uncontrollable power. Primal Fire, Agnia Flame, Divine Arrival, Angel Form. Merge together, Archangel Gabriel, in eternal harmony!"
After reciting the chant with unwavering determination, Nathaniel was enveloped in a circle of blazing fire. His body burned with flickering flames, but strangely, he felt no pain. The flames suddenly vanished, replaced by a new appearance.
Nathaniel stood before the academy sorcerers, transformed into a handsome young man with hair ablaze like burning fire. He wore a red robe with a symbol of fire on his chest, and on his back were six white wings shrouded in flames. In his hand, he wielded a sword engulfed in roaring fire.
