Chapter 930: I Am Eiji, the New Grand Duke of Hell!
He appeared openly before Eiji without bringing any subordinates, his entire body radiating an astonishingly immense demonic aura.
"Follow me, that is Asuque's territory!"
Without saying a word, Eiji set off with Barnier.
Under Barnier's guidance, they arrived at Asuque's territory. As the queen of succubi, countless beautiful succubus women lived here—their individual strength was very weak, relying on powerful demons for protection.
The moment Eiji landed, he raised his blade and charged toward the center of the territory.
"So straightforward!"
Barnier praised with delight, content to slack off on the sidelines.
As one of the Grand Dukes of Hell, Asuque's territory was exceptionally vast. However, most of her subordinates had likely gone to the divine-demon battlefield, leaving very few demons behind to guard it.
After Eiji effortlessly cut down several high-ranking demons as if they were mere vegetables, the succubi were utterly terrified and fled without a trace.
"It's you?!"
Asuque rushed out of her palace, her face turning as ugly as pig liver upon seeing Eiji.
"I never expected you to come to Hell, but here, I cannot be killed—"
"Taste my Light-Chaser!"
A blade light that dazzled the entire heavens flashed past.
Asuque died.
Along with all her remaining lives, she perished completely and thoroughly.
Eiji took a deep, slow breath, dispelling the fatigue from his body and mind.
The Light-Chaser strike was even capable of severing concepts and causality—its power was overwhelmingly strong.
However, its drawback lay in the need for a charging period, and it was a blow that concentrated all his strength—physical power, magical energy, mental focus, and causal force—all poured into a single strike. The consumption was even greater than that of the Reverse Demon Sword. If this move were dodged, he would likely have no choice but to flee.
Fortunately, during their previous battle, Eiji had already gauged Asuque's strength level and was confident she couldn't block this strike. Thus, he ended it with a single blow right from the start!
"...Is it over already?"
Barnier landed with an expression of disbelief.
"What did you expect?"
Eiji wore a look that said, "What else?" as he pulled out the Crozzo Demon Sword and incinerated Asuque's corpse into ashes, leaving her no chance whatsoever.
"Asuque is finished. How do I ascend to the position of Grand Duke of Hell?"
"Don't rush, everything will be handled by me!"
After the shock, what remained in Barnier's heart was boundless joy.
What a treasure he had found!
To kill Asuque with a single strike, severing all her lives—such power was something not even the gods of the celestial realm possessed!
Once he became a Grand Duke of Hell, why worry about the oppression from the celestial realm?
This was a huge gain!
As for Asuque?
I'll burn some paper money for you!
...
The Surface World.
Demon King's Castle.
Several days had passed since the new Demon King departed for Hell.
Jadeitis and the adventurers had left the Demon King's Castle that very day, including Kazuma and Darkness's party, all returning to their respective homes.
After Wolbach brought the executives back to the Demon King's Castle, the fortress once again fell under the control of the demon race.
Airi Yasaka stood in the training grounds of the Demon King's Castle, practicing basic fist techniques with meticulous precision.
"The ancestor is dead, our clan has been liberated. Airi, you should go and do what you love!"
The old Demon King father gleefully shared this news with her, then dashed into the human realm like a runaway horse—claiming he was off to have some fun.
With peace between humans and demons just around the corner, there was no longer any need to hide in the castle.
Moreover, the massive barrier enveloping the Demon King's Castle had weakened significantly ever since Eiji severed the connection to hell, making it far less impenetrable than before.
Additionally, the Crimson Demons who had stormed the castle that day seemed to have secretly recorded its coordinates. These past few days, Crimson Demons had been showing up daily as tourists, slipping past the barrier effortlessly and thoroughly annoying the castle's executives.
Airi Yasaka did not leave.
She stayed behind to wait for someone.
"Hey, practicing punches here? You're already tough enough—aren't you worried no one will marry you?"
The moment she heard that teasing voice, Airi reflexively threw a punch.
Smack! Her fist was effortlessly caught.
Before her stood a face she knew all too well. Though undeniably handsome, the sight of it always made her want to punch him!
"Is it over?" she asked.
"It's over," Eiji replied with a radiant, triumphant smile.
"I hereby declare that from today onward, you shall inherit the title of Demon King!"
Airi was momentarily stunned.
With her ancestors gone, she had long let go of her obsession with the Demon King's throne. Why was it being returned to her now?
"What about you?" Airi asked, a sense of unease stirring within her.
"Allow me to introduce myself—I am Eiji, the new Duke of Hell!"
Eiji flashed her an exceptionally bright smile.
With Barnier's assistance, he had successfully inherited Asuuk's position as Duke of Hell, gaining the authority to manipulate dreams. Having had his fill of the Demon King's role, it was time to dive into the games of a Duke of Hell!
Besides, there were plenty of alluring succubi over there!
"Can you grant me a dream?" Airi asked after a long silence, ultimately refraining from any words of persuasion.
She knew deep down that her influence wasn't enough to sway Eiji's resolve.
Instead, she made a single request.
"What kind of dream?"
Airi explained what she wanted.
Eiji gave her a surprised glance, then nodded in agreement.
Soon after, Eiji snapped his fingers. A hazy, dark mist dispersed and settled over Airi. A wave of drowsiness washed over her, and she naturally closed her eyes.
"Iris, I'm here to take you home!"
"Brother Eiji, you're finally back? Honestly, I'm never doing something like this again, okay?"
"Don't worry, there won't be a next time!"
In the dream, Airi forgot everything and returned to that morning in the Treasure Vault.
Before her was Eiji's retreating figure, and ahead was the monster disguised as the Sacred Sword.
Instinctively, she rushed forward and pulled him away.
On the training grounds, Airi opened her eyes, clarity dawning within them.
But the person she sought had already vanished from her sight.
...
Witnessed by Eiji, the Duke of Hell, and the goddess Eris, the new Demon King Airi Yasaka and the King of the Belzerg Kingdom jointly signed a peace treaty.
Before long, the succubus shop openly operated in the capital city's downtown area, while a human blacksmith's workshop appeared in the Demon King's Castle. Humans and demons finally achieved true peace.
Eiji certainly wasn't idle either. With peace restored in the surface world, he couldn't neglect the underworld.
He charged alone into the divine battlefield, beating every warmongering god from the celestial realm into swollen-faced messes. Throughout the vast heavenly realm, there wasn't a single deity who could stand against him as an equal!
He was human - the only transcendent being in the tens of thousands of years since the underworld's creation to attain the status of a Grand Duke of Hell while remaining human. Divine power held no restraining effect against him. Every time the celestial gods encountered him, they would be beaten relentlessly, one after another developing psychological trauma from the encounters.
