In such a tense mindset,
Elva even slowed down his attack on Ronald beneath the sarcophagus.
The threat to his security from an enemy completely unexpected and undetectable was too great.
Faced with this situation, Elva rapidly analyzed in his mind.
He was about to say that the only spells capable of successfully concealing themselves were from a very few schools.
The Council of Twelve Witches, the Clandestine Visitors, Master of All Spells...
Master of All Spells!
The Bureau of Investigation!
Was it a professional spellcaster directly under the queen from the Bureau of Investigation?
Standing on the soil of the whole city of Spring, Elva immediately targeted the Bureau of Investigation.
If there was anyone in this country he should suspect, it would be the Bureau of Investigation.
Elva’s level of vigilance in his heart had reached the highest level.
He was confident in defeating his enemy in battle, but if he and possibly even the queen were targeted by the Bureau of Investigation, his own... even the organization’s activities could be completely exposed.
Or Ronald and this unseen enemy.
Today, one side must be completely obliterated here; there was no other choice!
In the blink of an eye, he made a decision.
Elva had already devised his next tactics in his mind.
Then, the elderly caster began his performance.
His gaze lingered on the ground for a few seconds before Elva pretended to suddenly realize something and lifted his eyes.
His action was as if his current position was too high.
High enough that even in such a night, people in the surrounding blocks could possibly see in this direction and notice his solitary figure.
With a troubled expression, he supported himself with his original tome again and triggered a spell to change the terrain, causing the tall pillars to start lowering.
At the same time, the execution ground, resembling an inverted tack, also began to change structurally.
About two meters up from the top of the sarcophagus, a new stone wall extended from the pillars again; this time the spread was even faster than before.
In just the blink of an eye, a layer of new rock walls was constructed.
Adding another cover on top of the already securely locked execution ground.
Looking at the results under his feet, Elva nodded in satisfaction.
He seemed to trust his spell, believing that the enemy was trapped between the newly formed walls.
He snorted coldly, standing there, high above on the pillar now less than four meters tall, sharply observing the surroundings.
But unfortunately, with a change in the terrain,
the hidden enemy did not immediately give themselves away.
So Elva stood quietly in the night wind, the winter of Spring occasionally bringing the scent of the Wis River blowing on his face. At such an advanced age, even though Elva’s body had undergone several enhancements, it still inevitably shivered a bit from the cold.
At that moment of shiver,
a silver-blue light flashed in the dark night.
From beneath Elva’s position, this sudden attack struck directly at the elderly caster standing on the pillar.
However, facing this attack, the learned elder’s eyes sparkled.
A slight smile also inevitably appeared on his lips.
"I’ve been waiting for you to make your move..."
A spell that had been brewing for a long time was instantly activated.
Beneath Elva’s feet in the pillar, copious amounts of scorching, deep black liquid derived and immediately covered the area below him.
The silvery-blue light, although capable of breaking through the liquid barrier,
had deviated off course under the resistance interference, making it completely impossible to hit the top of the pillar where Elva was.
Soon, the black liquid beneath the feet of the old Caster solidified,
forming a pure black dome that completely sealed off the area beneath Elva.
In such a scenario, it was impossible for the enemy to escape.
Watching the breach he had purposely left succeed in luring the enemy, Elva couldn’t help but sneer:
"Agents of the Bureau, is this the best you can do?"
Swoosh-swoosh-swoosh—
As his words settled,
sharp stone spikes spread out in the next second.
In less than the time it took to breathe, they completely pierced through the entire space within the black dome. Under such circumstances, any flesh and blood body could only be pierced through and killed instantly.
Unfortunately for him, Claudia was not among them.
As Elva sneered, this girl, new to the battlefield, had already realized she had fallen into a trap.
While hiding her form, she quickly activated her Spell.
On the empty, stony ground, liquid surged out, corroding the stone surface, and instantly a circular pit collapsed downward.
Though the walls Elva had originally created were sufficiently sturdy,
in the face of Claudia’s most powerful corrosive Spell, their strength was no match for the power of the "Britannica Encyclopedia."
The exaggerated corrosive effect was even more than that.
After the first layer of ground was corroded through, it even eroded a hole into the dome above Ronald’s head.
With a thunderous rumble,
Claudia continued to fall,
and then she fiercely smashed into the foggy, genuine execution battleground!
At the same time, Elva, the controller of the Spell, also realized that the enemy hadn’t died.
Acknowledging his mistake, his cold gaze turned to two students lying on the ground.
Then, he coldly waved his hand,
selecting the ability he needed with practiced speed, and then he recited the incantation.
The upper and lower stone walls closed instantly.
Everything in between was shattered to pieces.
At this critical moment, Elva actually chose to kill his own people first!
As for the ground below...
After the recent attack attempt, Claudia had realized that her most adept Spell was unable to harm his body before he completed his defenses.
Her gaze swept through the surrounding pitch-dark fog.
Even in the pitch-dark environment, she seemed to have immediately determined something.
Thus, Claudia shouted loudly,
"Take action immediately!"
Matching her shout, the phantom of the original tome appeared again from the girl’s hands, hastily casting a Spell while Claudia rolled away from her previous position.
Following that, the girl’s Spell continued to take effect,
due to the suppression of the original tome’s priority.
In the moment before the upper stone wall could heal, she continued her attack, hurling highly corrosive liquid that immediately created an opening in the black dome overhead.
Simultaneously, the black fog summoned by Ronald finally got released.
Almost in an instant, the agile, swirling black fog gushed out through the crack,
Having been suppressed for so long and now regaining its freedom, the power of "Fury"
instantly enveloped the entire execution arena!
