Without even a shred of hesitation, Dabura immediately replied in a determined tone.
"I am."
He had already seen the corpses of his own people scattered accross the battlefield and that was his biggest sin of his life to let them die there.
If there really was a method which allowed their ressurection, he would happily sacrifice his life for it.
He would be more than willing for it.
"Then... Prepare yourself. I'm going to devour your life force."
Next second, Yahaech showed no mercy as he released his full power for a brief moment.
He vanished from his spot and appeared directly before Dabura. He extended his right hand and shoved it inside Dabura's chest before pulling it the instant.
Dabura's body no longer regenerated and light in his vanished, his body becoming lifeless as it fell on the ground.
What Yahaech just pulled out wasn't his heart, but the foundation of his existence —his soul.
The soul in his palm tried to run away, but before it could even attempt, it was suppressed to the limits and got refined instantly, turning into the pure lifeforce.
Among all realities, the strongest and most powerful energy which can exist is the lifeforce.
Every other kind of energy is nothing but a mere extension of it.
Yahaech was going to do something so impossible that it required a lot of cursed energy that didn't exist in entire universe if we were to aggregate all cursed energy present.
The only possible kind of energy that could help in his task was lifeforce energy. That's why he took Dabura's life.
"I need another soul."
Yahaech turned his head and looked into a particular direction, his senses piercing through the buildings and cities until it settled on a single person.
"You are semi-immortal. You have already lived your mortal life. Now that I plan to erase everything with tangible cursed energy from this universe, you have to die."
The next moment, Yahaech vanished.
*****
Yuji Itadori stood before a lake, his body bathed in warm sunlight of setting sun as looking at his own reflection, quietly pondering about what he had become.
His body neither aged nor he ever felt tired.
He was in a strange condition. He could feel the remaining humanity inside him slowly vanish, replaced by something entirely unknown.
He tried killing himself countless times, but always, like a cursed spirit, his body would heal itself like nothing happened to it.
His bones and flesh were slowly disappearing, his body becoming hollow to be filled with cursed energy the next moment.
Although, the transformation was extremely slow, he surely was changing into something unknown.
Unknown... he was afraid of this unknown.
He thought that he was cursed. Cursed with immortality.
Suddenly, he felt an overwhelming presence behind him, enough to crush his soul thousands of times.
After such a long time... he felt like a mortal. He felt the fear of a mortal.
He instantaneously teleported away from his spot when his instict that were honed through many decades of practice screamed at him to...run!
As soon as vanished, the space where he just stood twisted around before it was reduced into a small and invisible ball.
No one saw what just happened, but Yuji instinctively realized that he would certainly be heavily injured if not dead, if he had remained there any moment longer.
"Hm... You are also interesting..."
A mad grin appeared on Yahaech's face as he extended his hand to activate another technique.
But, Yuji was extremely fast. In less than a thousandth part of a second, he acted and shot dozens of dismantle at Yahaech, each dismantle refined and perfected enough to obliterate the entire cities.
And yet, to Yuji's surprise, the second technique that Yahaech was going to activate was already in effect.
The slashes that he had launched at Yahaech were entirely directed at him from his back.
If he hadn't counterattacked those dismantles from another set of dismantles, his body would be cleaved beyond recognition with the entire city he stood in.
From the moment, Yahaech appeared and Yuji dodged, not even a second has passed.
Only 2/1000th part of a second passed.
Yahaech became even more interested and poured a little more power in his next attack. He raised his finger and flicked it slightly.
Yuji's eyes widened when a crimson line appeared accross his right-hand shoulder and one of his four limb got severed from his body. Streams of blood sprayed out of his shoulder.
Ignoring his severed hand entirely, Yuji used his left hand and without any vocal incantation, opened his domain.
A sea of darkness emerged from behind of Yuji and immediately expanded outwards until it had enough size to blanket the Yuji with Yahaech in the domain.
"You domain is clearly inferior to the Infinite Void. You aren't worth of beholding my presence in your little dimension."
Yahaech swept his hand in a horizontal arc which instantly ripped through the darkness, opening a rift inside before the domain itself shattered into countless transparent fragments, clearly overwhelmed with the power.
10/1000th part of a second passed.
But Yahaech didn't stop there. He appeared next to the Yuji and gripped his entire face with a single hand.
The space occupied by Yuji's head began warping around a hole until his entire body was compressed into a small orb.
Yahaech then swallowed the orb, directly absorbing the entire lifeforce energy and semi-immortality of Yuji.
"Done!"
He said before disappearing again.
From the moment he appeared to the moment disappeared from here, only 20/1000th part of a second hand passed.
Yahaech himself admitted that among all the sorcerers, Yuji surpassed everyone by a imaginably large margin.
His instincts, reflexes and the control over his energy combined with the perfection he had of his techniques, made him the strongest sorcerer of all time with the sole exception of Yahaech of course.
*****
Yahaech materialized above the earth, not in sky, but in space.
His gaze fell over a large blue orb which was mostly filled of water with some of the areas covered with the various landforms.
This was the Earth. Over the past few thousand years, it had changed greatly. Continents has shifted, civilizations had risen and fallen, and humanity had evolved—all while the planet continued to provide the most precious gift of all: life.
It had given birth to him and various other humans. Those humans have given birth to the cursed energy.
He always thought she questioned himself: what was the strongest technique he had ever seen? Or rather, which technique had the most potential?
He had no answer of this question until he looked into the memories of younger generations where a extremely terrifying technique had appeared.
A technique capable to rewriting the reality itself.
But unfortunately, those generations could never use that technique to its utmost potential. They could never release it's full power and abilities.
Cursed Speech.
They added the word "cursed" to this technique while it should be the Divine Speech.
They used this Divine Speech in small sentences, while it should be used in long sentences.
Only Yahaech comprehended it's complete potential.
As wierd as it may sound, it provided him with a method to kill himself. To end his boring life.
He could end his life at any moment. But he restricted himself from ending his lifeforce without a great purpose.
But now, he had a purpose. He planned to put an end all the cursed energy in the world, erasing it entirely. He would also put a seal on the reality itself, so that it would prevent the cursed energy to materialize into curses.
Yahaech extended his hands and spread them outwards, raising his head to look into the dark outer-space.
Then... he began.
"I, Yahaech, hereby erase every trace of cursed energy from this universe. I seal reality itself, forbidding cursed energy from ever again manifesting into any tangible form or conscious existence.
I summon every Simurian—living and dead alike. Those who have fallen shall rise once more, restored to life, and all shall be returned to their rightful homeworld.
Let all things be restored to their proper order.
Furthermore, by my will alone, I command the river of time to reverse. Let the flow of history be undone. Let this reality return exactly eighty years into the past, with every decree I have spoken already woven into its very fabric.
I—"
Up to this moment, the remaining bit of Yahaech's existence had been completely erased, his smile never leaving his face.
He died grinning, with no regrets overall. And with him, the lifeforce energy of Dabura and Yuji had been also used to say those words.
Despite being few in numbers, every word carried immense weight behind them.
At this moment, the instant Yahaech's body disappeared entirely, an invisible wave spread, rippling through space and trampling on reality.
It was almost non-existent, no one could behold this wave of miracle which was soon about to change the heaven and earth, then the whole universe.
Wave expanded outwards at a terrifying speed, covering billions of light years in almost an instant, until it touched the boundaries of known universe.
The moment it touched those boundaries, it vanished.
But, before disappearing, it rewrote the reality.
Time was reversed and Cursed Energy was sealed.
