A chill ran down Black Demon's spine.
It was the first time in his life that someone else's laughter had given him goosebumps.
"Y-You bastard!"
Perhaps his pride was hurt by this fact, as Black Demon's face twisted in anger.
"Fine. If you wish to die so badly, I'll show you!"
Soon, he revealed his full power without holding anything back.
Kuuuung.
His true strength that had gained notoriety long ago during the great battle between the Orthodox and Demonic factions.
An incredibly terrifying aura, completely different from before, began to emanate from his body.
\[Destruction Star-Absorbing Art\]
Five crimson energy orbs began spinning above Black Demon's remaining hand.
Soon, as he extended his hand,
Shwaeeeek! Shwaeeeek!
The five energy orbs flew towards Yeo Un-hwi one after another, making a sound like they were tearing through the air.
It was a momentum as if it would swallow the world whole.
But,
Slash. Slash. Slash. Slash. Slash.
Yeo Un-hwi cut down all the energy orbs flying towards him.
Without even disturbing his breathing.
But this wasn't the end.
Even though all his attacks had been nullified, Black Demon's face showed no sign of yielding.
"I see. I didn't think it would work so easily. Then how about this?"
Black Demon slowly raised his hand.
"Hnngh!"
Suddenly, his eyes became bloodshot.
Then, an incredibly terrifying energy, incomparable to his previous attack, began rapidly growing above his hand.
Kugung. Kugugung.
In an instant, the black energy grew to the size of a house, with large and small sparks flying around it.
An overwhelming pressure could be felt.
Even at a glance, it looked like an extremely dangerous technique.
Watching this scene, Yeo Un-hwi's eyes widened slightly.
It seemed even he was surprised this time.
Black Demon smirked.
"It's already too late to regret. For the crime of not knowing your place and acting recklessly. Pay with your life!"
Black Demon thrust his hand forward.
\[Destruction God Palm\]
Soon, that massive black energy began moving towards Yeo Un-hwi.
With a momentum as if it would completely shatter the world.
Black Demon had no doubt. That his Destruction God Palm would lead that arrogant fellow to death.
Kwaaaang!
Crack!
Wherever the Destruction God Palm passed, the ground cracked and split open.
But then,
"Getting so full of yourself so quickly. Tsk."
Yeo Un-hwi let out a small laugh as he lowered his stance slightly and slowly gripped his sword.
Then he took a brief moment to regulate his breathing.
Whoo.
The moment Black Demon's attack came right up to his face.
Yeo Un-hwi's eyes flashed as he swung his sword forward with all his might.
Then,
Shwaaaak!
Kwaaaang!
With the sound of something being cleanly cut, a massive explosion occurred.
That explosion swept away half the forest.
And then...
"H-How... Kuuugh..."
Black Demon also collapsed, spewing blood.
Hmm.
Yeo Un-hwi slowly approached the fallen Black Demon. He was no longer moving.
Was it over?
That's when,
Twitch.
Black Demon's body moved ever so slightly.
Jegal Gil's eyes caught that movement.
Even from far away. No, it would be more accurate to say he sensed it.
It was possible because he was none other than Jegal Gil.
"B-Be careful!"
Jegal Gil urgently called out to Yeo Un-hwi.
Hm?
For a moment, as Yeo Un-hwi turned his head towards Jegal Gil,
Whoosh!
Grab.
Black Demon suddenly raised his body like lightning and grabbed Yeo Un-hwi's arm.
"Kuhaha. You let your guard down, you bastard!"
Black Demon laughed maniacally.
He hadn't expected even his Destruction God Palm to work on Yeo Un-hwi, but now that he had caught him like this, it was all over.
His 'Destruction Star-Absorbing Demonic Art' would absorb all of the opponent's internal energy and life force until they died.
Unless Black Demon himself allowed it, Yeo Un-hwi could never escape from his grasp.
Now this arrogant brat would die experiencing terrible pain.
"The Star-Absorbing Demonic Art, is it?"
"Kuhahaha! Begging is useless. You will die in the most miserable and horrific way."
"Is that so?"
But what confidence was this?
Yeo Un-hwi's face showed not the slightest sign of panic.
Rather, he looked amused.
"Go ahead. Let's see what happens."
"Hmph. To put on such a useless bluff even at this moment."
Black Demon thought Yeo Un-hwi was putting on unnecessary bravado.
Certainly, Yeo Un-hwi was a master beyond his expectations.
But from now on, things would be different.
This young brat simply didn't know the terror of the Star-Absorbing Demonic Art at all.
Such bluffs wouldn't work.
"You foolish brat. I'll make you taste hell!"
Whoosh.
Soon, Black Demon activated the 'Destruction Star-Absorbing Demonic Art' and began sucking in Yeo Un-hwi's internal energy.
Immediately, Yeo Un-hwi's internal energy began being absorbed into his body at an incredible speed.
It was truly an enormous amount.
"Ohhh. You bastard. You had such tremendous internal energy!"
Black Demon was utterly shocked.
The amount of Yeo Un-hwi's internal energy was already far surpassing what Black Demon originally possessed.
To have this level of internal energy at this age... There wouldn't be many in the world with such internal energy even if you searched all under heaven.
How on earth did this young brat have such internal energy?
But it was all useless now, as all his internal energy would become Black Demon's.
With this internal energy, even though he had lost an arm in this incident, he was certain he would become twice as strong as before.
From Black Demon's perspective, this arrogant brat was like the greatest elixir he had just discovered.
Keukeukeu.
He felt as if he had obtained the world.
He was lucky. To have met such a brat here.
Conversely, this arrogant brat was unlucky.
With such internal energy and martial arts, he would have soon become an incredible master whose name would shake the world.
To meet him before that.
He could already feel his dantian swelling up as an enormous amount of internal energy was filling his entire body.
Keukeukeu.
He thought that perhaps he might be able to take one of the Ten Great Demon Star positions, displacing 'that person'.
With this internal energy, it wouldn't be impossible. Yes, of course!
Black Demon's face was becoming colored with greed and ecstasy.
But then,
"Feeling good, old man?"
"Hmm? Ah, no..."
Black Demon had momentarily forgotten while feeling the internal energy filling his entire body.
He had thought that as soon as he activated the Star-Absorbing Demonic Art, Yeo Un-hwi would naturally struggle in agony before losing consciousness.
But Yeo Un-hwi looked completely unaffected. Surprisingly so.
Rather, he was calmly staring at Black Demon with an indifferent face.
Then,
"You spoke so confidently, but is this all you've got?"
A small smile formed on his lips.
"Y-You bastard, how..."
The Star-Absorbing Demonic Art wasn't something where the opponent could put on airs or not.
The moment one's internal energy was sucked away, they would inevitably feel tremendous pain.
And that pain wasn't something a human could easily endure.
Especially for a martial artist, it would be even harder to bear.
Unless one had nearly infinite internal energy, this was impossible.
"Eeek!"
Black Demon, whose composure had completely disappeared, raised the level of the Destruction Star-Absorbing Demonic Art with all his might, his face drained of blood.
Whoosh!
But even so, Yeo Un-hwi remained the same.
He was still staring at Black Demon indifferently with eyes that didn't waver in the slightest.
No, now he even looked bored.
"H-How..."
Suddenly, Black Demon felt goosebumps all over his body.
Could it be... that his internal energy was really close to infinite?
Is that even possible? That's not something within the realm of human possibility...
Whoosh.
'Th-This is already...!'
Meanwhile, Black Demon suddenly felt the internal energy in his body overflowing and about to burst.
He could no longer handle any more than this.
Moreover, at this point, even if one had extremely powerful internal energy, a normal human should have had all their life force absorbed and become a corpse.
But Yeo Un-hwi was still completely unfazed.
Gulp, gulp.
Ugh.
Even as this was happening, Yeo Un-hwi's internal energy continued to pour into Black Demon's body.
I-I need to stop now.
At this rate, there will be side effects on me...
Soon, he tried to slightly remove his hand from Yeo Un-hwi.
But before he could do so, this time Yeo Un-hwi grabbed Black Demon's arm.
"Oh my, where are you going? Hm?"
"Y-You bastard! Let go of this!"
Black Demon shouted in a panicked voice.
The Destruction Star-Absorbing Demonic Art was still in effect.
To stop it, he needed to separate once.
But before he could separate, Yeo Un-hwi had grabbed his arm, so the Destruction Star-Absorbing Demonic Art wasn't stopping.
Having consumed so much internal energy, Black Demon's belly was already swelling up.
"Let go! I said let go!"
"Why? If you've started, you should see it through to the end. Don't you think? Go ahead and taste whether I'm an elixir or poison until the very end."
Yeo Un-hwi's smile deepened.
And then,
Kuuuung!
As his eyes flashed, the amount of internal energy being absorbed by Black Demon doubled.
Whoosh!
"Aaaack! S-Stop! N-No! Nooo!"
Black Demon screamed in an urgent voice.
But Yeo Un-hwi had no intention of stopping at all.
Gulp, gulp, gulp.
Soon, Black Demon's body began to swell up.
"Kuheeeek. Kukukuk."
Black Demon's body, which had swollen up like a balloon, then exploded with a loud bang.
Kwaaaaang!
A huge cloud of dust rose.
As the dust gradually settled, the only person left standing on two feet was Yeo Un-hwi.
"...Kuuugh. Y-You bastard."
Even though his body had burst and only his upper body remained, Black Demon was still clinging to life.
He would die soon anyway, but even so, it was a vitality that was hard to consider human.
Demonic arts were this tenacious and terrible.
"Who... the hell are you... What are you..."
Black Demon was curious about that until his dying moment.
That's how unbelievable Yeo Un-hwi's power was.
It was a power beyond imagination.
It was regrettable that he couldn't report the existence of such a dangerous man to his sect, but there was nothing he could do now.
Looking down at the slowly dying Black Demon, Yeo Un-hwi answered with an indifferent face.
"I'm... the son-in-law of the Hebei Peng Family."
"What?"
Black Demon let out a hollow laugh at Yeo Un-hwi's unexpected answer.
Was he mocking him as he was dying? Or was it true?
In any case, it was quite an absurd identity.
His eyelids were gradually closing.
"Ha, haha. Son-in-law... Crazy."
Thud.
Soon, Black Demon's body went limp.
His tenacious life had finally come to an end.
Black Demon, one of the Ten Great Demon Stars representing the Demonic Cult, had now met his death here.
He probably hadn't expected it either.
That he would meet his end here in Hebei.
And at the hands of the son-in-law of the Hebei Peng Family, no less.
The tremendous battle that had unfolded in the middle of the night thus came to an end.
But since there were only mountains all around, no one would know about this battle.
Except for one person.
"H-Haha... To think you really defeated Black Demon..."
Jegal Gil stared at Yeo Un-hwi with a blank face.
It was hard to believe even after seeing it.
Not only had he fought evenly against one of the Demonic Cult's Ten Great Demon Stars, but he had overwhelmed and defeated Black Demon with absolute power.
"Are you alright?"
Yeo Un-hwi slowly approached and asked. But who was in a position to worry about whom right now?
"Y-You... Just who are you... And what exactly happened here?"
He had nearly died.
If Yeo Un-hwi hadn't appeared here, he would certainly have been unable to avoid death.
But true to his nature as an investigator, even in this situation, he was asking questions.
However, Yeo Un-hwi merely gave a strange smile without answering.
That's when,
"I will answer that question."
Another voice was heard from somewhere.
The one who soon revealed himself was Peng Seo-jin, the Eldest Young Master of the Hebei Peng Family.
Jegal Gil's eyes widened immensely.
