At this time, Kyle was cloaked in the shadows of the forest just outside the Academy

He could feel the presence of various barriers, but he didn't think too much of them as he prepared to join the fray if necessary.

The reason he was here was simple: he wanted to hunt the Deadly Sin, which is similar to what the Farrel Academy wished to happen.

Kyle moved through the Academy's barriers by manipulating its shadows.

He moved with no sound and his presence was as imperceptible as a fleeting thought.

'What an incredible fluctuation of energy' Kyle mused.

He was drawn to the epicenter of the psychic disturbance, where the battle against Envy was about to escalate.

Outside the Chamber of Seals, Lysandra did her best to ensure that the doors were kept shut as the Headmaster and the others worked together to defeat Envy...

Although the Chamber of Seals was incredibly strong, as it was made by the Academy's top Arcanists, there was certainly a limit.

According to textbooks, it could theoretically seal even an Immortal.

However, it was never tested to an Immortal and was only used against Half-Immortals.

Because of that, Lysandra couldn't help but feel nervous.

She could only pray that the Headmaster and the other professors are doing well!

***

Inside the Chamber of Seals, the Headmaster stood at the forefront, flanked by eight Professors, each of them already considered as masters of their craft.

Their eyes were set upon Envy, who writhed within the confines of the psychic prison

To their dismay, the Chamber of Seals only allowed them to stop the Deadly Sin from calling out for external help or energy.

It felt as if the one they were facing wasn't a mere Spirit or Avatar It was as if they were dealing against the true Envy!

"Focus!" Headmaster Therion shouted.

Envy's aura, a miasma of green, pulsed against the chamber's wards. It felt as if it could break the shackles they had placed at any moment.

"Begin the incantation"

This was commanded by the Headmaster, his voice resonated through their heads as he used telepathy to give out commands.

This was actually very impressive since the Headmaster was already casting three spells at the same time. The telepathy must be the fourth spell!

Nonetheless, the Professors had no time to be impressed!

In unison, the Professors began to chant, their voices weaving an upsurge of ancient syllables. The chamber's runes glowed brighter, creating a symphony of light against the encroaching darkness, which was the Deadly Sin!

Envy, sensing the tightening burst of psychic energy, unleashed a barrage of ethereal assaults.

Waves of malevolent force crashed against the barriers, each impact a test of the chamber's foundation!

Indeed, Envy was using a brute force to fight against the Psychic Arts while protecting herself using his mental energy that rivals all the Psychic Arts in the room!

The Headmaster raised his staff and a burst of mental energy was released from it

"Focus your minds" he urged. "We must synchronize to eliminate this evil."

The other professors felt a burst of mental energy. However, it wasn't harming them. As a matter of fact, it was replenishing their exhausted minds!

"Synchronize!"

The Professors, attuned to his command, aligned their psychic flows into a singular, unbreakable stream. The chamber responded; its runes hummed violently, a harmonious counter to Envy's discordant rage!

Envy roared, a sound that transcended the physical, echoing through the minds of all present. It thrashed against the psychic bonds.

Then, its physical form started flickering, as if it was trying to become a specter to safely escape the Chamber!

"Strengthen the seals!" Shouted by one of the Professors, her hands outstretched as arcs of psychic energy leapt from her fingertips.

The others followed suit, their powers manifesting as psychic chains were cast to strengthen the seals of this chamber

Envy's struggle grew desperate, its form contorting, seeking any weakness, any lapse in concentration. But the Professors were at an advantage with the help provided by the Chamber of Seals and the Sovereign Artifact being wielded by the Headmaster.

"They're a lot stronger than I expected"

Kyle, from his vantage point, watched the spectacle with keen interest.

After reaching the central part of the Academy, he was able to sense Envy's power.

To be honest, he felt as if Envy had been in the Human Realm for a very long time as he felt incredibly powerful and Envy doesn't seem to be an Avatar or a Spirit that was sent here because of how stable his power was.

Without a doubt, Envy had the power similar to a True Immortal.

However, the Psychic Arts was just too difficult to deal with.

In front of this Arcane Art, your physical power and your spiritual strength don't matter! They will attack your mind, your will, or your soul!

It wasn't something that Arcanists of different paths would focus on except for some branches in the Arcane Path itself.

'It looks like they're winning, but the Deadly Sin isn't being serious yet' Kyle thought after observing the situation for a while.

Boom!

The Chamber of Seals trembled as the Deadly Sin burst with power.

Nonetheless, the Psychic Arts Practitioners' display of power was impressive, their unity in the face of such a formidable foe was proof of their training and discipline.

***

Kyle observed the spectacle, his interest piqued not only by the Deadly Sin's desperate attempts at liberation, but by the potential of the Psychic Arts Practitioners.

Their technique, their control, their finesseall elements he sought to understand, to perhaps incorporate into his own repertoire of shadowy abilities.

'I should really extract these guys' Kyle mused for a moment as he surely wanted to obtain those abilities. It also felt like obtaining more Psychic Arts would allow him to have more control over his spells.

Nonetheless, as the time passed, the battle to bind Envy intensified. Headmaster Therion, joined by other expert psychics of the Academy, channeled their collective energies into reinforcing the chamber's wards and breaking the mind of the Deadly Sin

However, Kyle realized that the Headmaster's Sovereign Artifact was getting weaker and weaker. It could no longer replenish the mental energy of the Professors while Envy was still trying its best!

***

"Two minutes at most" Headmaste Therion warned the other Professors.

The battle within the Chamber of Seals reached a fever pitch as the Sovereign Artifact in his possession was already at its limit...

The staff was already trembling as it was already being overused

It was faltering, its once radiant light dimming to a mere flicker.

Envy, seizing upon this weakness, redoubled its efforts, lashing out with renewed vigor. The chamber trembled under the onslaught, the air thick with the tang of psychic fire.

"What a pity So this is all you can do?" Envy finally spoke and it was a voice of disappointment. It was as if all of his struggles just now were merely an act.

However, the wasted energy of the Deadly Sin was definitely real!

As Psychic Arts Practitioners, their minds were extremely strong and they wouldn't falter on such a simple provocation.

Nonetheless, the Headmaster's brow furrowed in consternation. It doesn't change the fact that they were failing to kill the Deadly Sin

'This Sin is not a mere summoned spirit or avatar It feels as if we're dealing against the true Sin' Headmaster Therion frowned as he didn't think that the real body of the Sin would really enter the Human Realm that was being protected by a true Immortal.

Anyway, he tried to contact the members of the Oracle Hivemind once again but he wasn't getting anything.

The Order of the Oracle Hivement, the reinforcements he had summoned, were still nowhere to be seen, likely ensnared by other demonic machinations.

Time was slipping through their fingers like grains of sand, and with each passing moment, their control declined.

With a heavy heart, Headmaster Therion prepared for the last resort.

Once the Sovereign Artifact failed, he would unleash a spell to expel Envy from the Academy's hallowed grounds.

The consequences of such an action weighed heavily upon him; the Deadly Sin could wreak havoc wherever it landed, endangering untold lives.

Yet, the immediate threat to the Academy left him with no alternative.

'Once this being is gone, we will have to evacuate' The Headmaster thought as he readied himself to use the Second Arcane Path he had learned to blast Envy away

He also controlled the Chamber of Seals to open it once he was ready to expel the Deadly Sin.

As he channeled the Elemental Spell, the surrounding air intensified as the other Professors realized the Headmaster's plan

The chamber's runes glowed ominously, a prelude to the expulsion. But just as the Headmaster was about to release the spell, a shadowy figure materialized within the chamber.

The psychics faltered briefly as their concentration was broken by the sudden intrusion.

The figure emerged from the darkness, its form cloaked in an aura of impenetrable shadows.

Kyle stepped forward, his eyes reflecting the chaos of the battle.

"Stay your hand, Headmaster," Kyle's voice resonated through the chamber, a calm amidst the storm. "There is another way."
