Straight Death Demonic Eye.
This was a new ability Duan Chen possessed after integrating the Royal Chess piece, one he had never used before.
One reason was that this particular eye technique consumed an exceptionally vigorous amount of spiritual energy, and he was worried he wouldn't be able to control its consumption if he used it.
Another reason was that, judging solely by the name of this eye technique, one could understand what type it was.
He had never reached a point where he needed to use this eye technique.
He knew this eye technique possessed extremely powerful destructive capabilities. Ever since this ability belonged to him, he had understood from the depths of his heart how to use it.
When it came to eye techniques, for him, they were the easiest to understand.
It was precisely because it was so easy to understand that it made him feel fear, a fear of the powerful ability he was about to possess.
This was no joke. However, now, under the surge of anger, Duan Chen had completely forgotten his fear of mastering power.
Duan Chen could no longer hold back.
His eyes were ice-cold, filled with a bloodthirsty aura.
The Straight Death Demonic Eye activated instantly. The entire world as Duan Chen saw it underwent a drastic change.
Square, round, right-angled, obtuse…
All curves, all arcs, in his eyes, faded away, transforming into countless straight lines.
Every object within his sight had its own outline, a line known as the 'slay line.'
As long as he made a slight graze—
He could even keenly sense that if he traced along this black line, stroke by stroke, the object he depicted would vanish.
It would be a true erasure of existence.
Never to exist again.
Neither in the present, nor in the future, nor in the past.
It would be completely annihilated.
The Sea Demon Priest sensed something was amiss at this moment.
But he didn't know where this bad feeling was coming from, only that his heart was filled with extreme unease and panic.
He strained his eyes, trying to see what was threatening him.
But besides Prince Hao, who looked somewhat pale and was hiding behind Duan Chen, all he could see was Duan Chen standing in front of Prince Hao.
That sense of unease continued to linger in the Sea Demon Priest's heart.
He roared in shame and anger.
"Is it you, damn human, causing trouble? I'm telling you, no matter how you threaten my mind, I will absolutely not let you go."
But he didn't notice at all that Duan Chen's entire eyes had turned a complete black, incapable of refracting any light – a color like a black hole.
All light that entered his eyes was absorbed. The world his eyes could perceive was no longer the same as the three-dimensional world a normal person could see.
Duan Chen even felt a force manipulating his mind, making him gradually become indifferent.
The Royal Chess piece contained within his body suddenly trembled.
A somewhat warm power emanated from the entire white chess piece, instantly dispelling the faint divinity Duan Chen was feeling.
He snapped back to reality with a jolt. His complexion had turned somewhat pale.
In that instant, only eight seconds had passed, but for Duan Chen, it felt like a year.
He saw black lines on most people around him. These black lines densely wrapped and surrounded the Sea Demon Priest.
And as he turned his head, he also saw the black lines on Prince Hao. There were significantly more black lines on him than on the Sea Demon Priest.
Duan Chen could perceive how terrifying this power was.
He also felt incredibly fortunate in his heart.
The Royal Chess piece had awakened him in an instant. Otherwise, he might have directly sunk into this power, unable to break free, becoming a pawn controlled by it.
He took a breath, forcing himself to stop dwelling in the intoxicating feeling of controlling such power.
His gaze landed on the Sea Demon Priest opposite him.
In his eyes, the black lines were constantly shifting. But he understood clearly that with just a thought, he could erase a black line. As long as he could erase any one of them, the entire object before him would disappear.
This was the terrifying aspect of the eye technique he now possessed.
However, Duan Chen also understood that using such intense and powerful energy would undoubtedly come with a terrible price.
It would likely drain about one-fifth of his stored spiritual energy.
This meant he could only use this method to kill five people.
No, wait, it should be four.
Calculating it this way, it seemed quite worthwhile.
Duan Chen couldn't help but laugh at his own thoughts. Then, without any further hesitation, he raised Pandora in his hand, transforming it directly into a Tang Dao.
Time around him seemed to freeze, allowing him to approach the Sea Demon Priest in an instant. The Sea Demon Priest's eyes flashed with surprise, revealing a triumphant smile.
He couldn't help but burst into laughter.
"I was still wondering how to get close enough to you for my tentacles to touch you, and you actually walked right into my trap, you fool."
Prince Hao was stunned.
What was going on with his instructor? How could he suddenly slide so close to the enemy?
Duan Chen had no intention of explaining himself to anyone.
In an instant, as he closed in on the Sea Demon Priest, the blade in his hand swept across.
At this moment, the Sea Demon Priest didn't have time to resist, or rather, by the time he realized it, he found that his body was paralyzed, as if forcibly immobilized. Even with all his might, he could only slightly shift his body.
How could this be? Why would something like this happen?
As the Sea Demon Priest died, this was the last thought that remained in his mind.
Duan Chen silently watched the ashes before him, like blank paper burned to dust, disintegrating.
He said coldly.
"This is the only kind of death you deserve."
Whether in the past, present, or future, there would be no possibility of life. All world lines were severed, erasing any possibility of existence.
This was the Straight Death Demonic Eye.
And it was at this moment that Duan Chen's mind suddenly stirred.
Prince Hao also suddenly stood up, looking around in horror and shouting.
"No, Instructor, this is a link in the formation's core!"
