Crossover Anime: Starting by fusing with an old sword and summoning Morgan

Deep underground in the mountains behind Koma-o Town, where the Fairy Palace has been built.

A portal emanating dark red magical energy slowly took shape in the spacious obsidian hall.

This was not a spatial passage that Luo Chen casually tore apart from the dimension, but a special transfer passage for the "Rating Game" personally constructed by Achuka Beelzebub, the highest-ranking official of the Underworld Technology Development Bureau and the current Demon King.

Rias Gremory stood before the portal, holding up the hem of her maid outfit with both hands, and took a half-step back with utmost respect, making way for her "masters" who were about to enter the battlefield.

"Lord Luo Chen, the passage has been stabilized."

Rias lowered her eyes, her tone carrying a complex emotion.

Behind this door lies an alternate dimension prepared by the underworld specifically for this "special demonstration battle".

For demons, it is the ultimate stage to showcase their family's power and stake their glory.

But in her view, this door was more like a meat grinder about to completely crush the ridiculous pride of the underworld.

"Let's go."

Luo Chen had one hand in the pocket of his black casual trousers, and the other casually rested on Artoria's shoulder.

He didn't even change into his imposing black trench coat today, but wore a slightly loose white shirt, exuding a lazy vibe as if he were just going for a walk.

Beside him, Morgan le Fay held up his iconic black magic umbrella, the hem of his purple haute couture trench coat swaying gently in the magical breeze.

Scáthach fiddled with the red gun in her hand, a hint of boredom flashing in her wine-red eyes.

As for Artoria (Saber), she is the most serious of the three.

Although he was still wearing that refreshing blue and white casual outfit, his emerald green eyes had already entered a state of absolute battle readiness.

The four of them strolled leisurely through the red portal of light.

……

The Underworld, a special alternate dimension exclusively for showcasing battles.

The moment Luo Chen and his group stepped onto this false land constructed of magic.

A gust of hot wind carrying a strong smell of sulfur rushed towards me.

The terrain of this alternate dimension was deliberately arranged to resemble a desolate, massive canyon filled with jagged, bizarre rocks.

There was no sun in the sky, only a huge magical sphere emitting a dark red light, serving as the source of light.

"What a laughable, crude creation."

As soon as Morgan landed, her ruby-like eyes revealed undisguised utter disdain.

She tapped the seemingly hard rock beneath her feet lightly with the tip of her high heel, letting out a cold snort.

"Using inferior remnants of earth veins, they forcibly pieced together the extension of space. This 'world,' filled with traces of artificial stitching, has spatial barriers that are even thinner than the defensive barriers in my Fairy Kingdom's sewers. Is this what this world calls 'top-tier technology'?"

"After all, they are native demons, so we can't have too high expectations, Morgan."

Luo Chen looked up and glanced around.

His gaze did not linger on the surrounding canyons, but instead pierced through the false spatial barrier, looking directly at the "monitoring center" hidden outside the space, which was operating at full speed.

……

The Underworld, the central viewing hall.

This is a huge circular venue that can accommodate thousands of people.

At this moment, the heads of the major families in the Underworld, pure-blooded nobles, and high-ranking representatives from the Celestial Realm and the Fallen Angel camp have all gathered here.

In the center of the venue, a huge magical water mirror floated, clearly broadcasting the scene inside the alternate dimension canyon from all angles without any blind spots.

Compared to the whispers and discussions among the ordinary demon nobles, filled with disdain and curiosity, the three faction leaders sitting in the front row of VIP seats—Sazex, Michael, and Azazel—had expressions so solemn they seemed to drip water.

"They're coming in..."

"Sazex, who did you choose as your opponent?"

Michael asked, frowning.

"Arranging a weak opponent in this setting might displease His Excellency. But if..."

"I have no plans."

Sazex gave a bitter laugh, his eyes revealing a deep sense of helplessness.

"It's those old fogies in the Elder Council. They simply don't believe what we've been through in the human world, and they think our long-term peace policy has led to our weakness. So, they jointly elected a collateral branch of the 'Bael' family, known for its fighting prowess, along with several up-and-coming nobles who are dissatisfied with the existing Demon King system, to form what they call the 'Strongest All-Star Team'."

"The sixteen chess pieces are all composed of pure-blooded elites who possess the strength of a high-level demon, or even approach the level of a supreme demon."

Sazex sighed.

"They wanted to use sheer numbers and violence to publicly execute the three female subordinates in this competition, which was being broadcast live throughout the entire underworld, in order to prove that 'the majesty of pure-blooded demons is inviolable.'"

"A bunch of idiots who're asking for it."

Asahiel cursed without holding back, then looked at Achuka Beelzebub, who was operating the equipment next to him.

"Achuka, are the readings on the monitoring equipment normal?"

"That's strange..."

Achuka pushed up his glasses, cold sweat beading on his forehead.

"From the moment they stepped into the alternate dimension, the underlying logic of the entire 'Rating Game' malfunctioned. That man in black... the system couldn't read any of his existence values ​​at all. At his coordinates, the system's assessment was—'Cosmic Mass Black Hole'."

……

An alternate dimension, in the center of the canyon.

"boom--!!!"

As more than a dozen dazzling beams of magical light descended from the sky, sixteen figures clad in magnificent armor and with demonic wings spread across their backs landed heavily on a rocky hill less than a hundred meters away from Luo Chen and the others.

Leading the group was a burly, muscular, and grimacing demon nobleman.

He held a giant battle axe that exuded an aura of destruction in his hand, looking down at the four people below, and let out an extremely arrogant laugh.

"Hahaha! I thought the one who scared that coward Sazex out of his wits was a three-headed, six-armed monster! Turns out it's just a pretty boy and three delicate women!"

The demon nobleman slung his battle axe over his shoulder, his lewd gaze sweeping over Morgan, Scáthach, and Saber.

"Hey! You human over there! I heard you said that if we can force these three women back even half a step, we'll consider ourselves the winner?"

"How arrogant! However, considering how stunning these three women are, I'll grant you a quick death! After I kill you, I'll take these three women back to my manor and give them a proper 'training'!"

"Roarooooo—!!"

The fifteen demonic minions behind him also let out wild, maniacal laughter, as various colors of destructive magic and elemental attacks converged in their hands.

The combined magical pressure of the sixteen high-ranking demons did indeed make the air in this canyon scorching hot.

"...What is he saying?"

Scáthach tilted her head slightly, picked at her ear with her little finger, and there was no anger in her wine-red eyes, only a pure bewilderment as if she had seen some extremely rare and incomprehensible single-celled organism.

"Master, do the natives of this world have some kind of congenital genetic defect in brain development? Why do they always like to make such illogical declarations of suicide before they die?"

"Who knows? Maybe they're just taking advantage of their numbers."

Luo Chen chuckled lightly, his hands still in his pockets, and he didn't even change his posture.

"Since they're so eager to die, as guests, we should at least grant their wish."

Luo Chen raised his eyelids, a cold, sharp glint flashing in his crimson-gold vertical pupils.

"Saber. Scáthach. Morgan."

"exist."

Three peerless kings/queens responded simultaneously.

"That stupid pig that squeals with an axe, its tongue is really annoying."

Luo Chen's voice echoed through the canyon, casually announcing the end of the match.

"One minute."

"Clean them all up. Don't let that filthy blood splatter on me."

"One minute? Master, aren't you underestimating me?"

Scáthach's lips curled into a cruel smile as she gripped the [Piercing Death Spear] in her hand, which had transformed into a dark red streak of light.

"Arrogant humans!! Tear them to pieces!!!"

The demon nobleman was completely enraged, and he roared as he gave the order for a full-scale attack.

Sixteen high-level demons simultaneously unleashed their strongest magic, transforming into more than a dozen streaks of light that swept down upon the four people below!

The magic circles stacked in layers in mid-air, and countless attacks, powerful enough to destroy mountains, rained down like a storm, including flames, lightning, venom, and shadows.

Faced with this devastating offensive.

"—Strike Air!"

Artoria made the first move.

She did not reveal the true name of the Holy Sword, nor did she perform any complicated actions.

She simply gripped the invisible sword enveloped in the gale with both hands, and facing the barrage of magical attacks, unleashed an extremely simple and unadorned upward slash!

boom----!!!

With the magical blessing of Luo Chen's [Infinite Ether Furnace Core], even a basic attack without releasing its true name has reached an astonishing [City-level] power!

The raging golden hurricane transformed into a storm tornado connecting heaven and earth, instantly shredding all the incoming magical elements into powder like tearing apart paper!

Not only that, the terrifying wind pressure continued its relentless advance, slamming violently into the four demons "Rook" and "Knight" who were charging at the forefront.

"What... what kind of sword pressure is this?!"

The four demons, renowned for their physical defense and speed, felt as if they had been hit head-on by a high-speed interstellar train the moment they came into contact with the Wind King's barrier.

Their prized demonic scales and magical defenses shattered instantly!

"Pfft!"

The four of them coughed up a mouthful of blood in mid-air, their bodies flying backward like kites with broken strings, crashing heavily into the distant rock wall, their fate unknown.

Just one sword strike.

It directly evaporated the combat power of four high-level demons!

"How...how is this possible?!"

The demon nobles were terrified.

But before he could change tactics, a ghostly purple figure appeared on his flank as if by teleportation.

"What's the difference between your speed and that of those insects crawling in the mud?"

Scáthach's voice, like the whisper of death, rang in his ears.

"—Gáe Bolg!"

Scáthach didn't even try to stab him in a vital spot; she simply swung the shaft of her spear, striking the demon nobleman hard in the side with the spine of the spear as if hitting a baseball.

Click!

A sickening sound of bones cracking.

The demon noble's massive body was folded into a bizarre "V" shape!

He didn't even have time to scream before he crashed into the ground like a cannonball, creating a crater more than ten meters deep.

"Boss!!!"

The remaining eleven demon servants were completely panicked.

"Kill her! Kill that purple-haired woman now!!"

The Bishop and Queen behind her frantically gathered the highest-level destruction magic, attempting to launch a devastating attack on Scáthach.

however.

"How noisy, you mongrels."

Morgan le Fay, who had been holding back until now, finally slowly raised his eyes.

She didn't move an inch, simply standing beside Luo Chen, extending her right hand, clad in a black lace glove, towards the demons chanting magic in mid-air, and gently—

He snapped his fingers.

Snapped.

The crisp snap of fingers, however, sounded exceptionally clear amidst the chaos of the battlefield.

next second.

The sky in the entire alternate dimension suddenly turned into an extremely deep, dark blue.

Countless ancient fairy scripts, extremely complex and seemingly containing the laws governing the birth and death of stars in the universe, appeared in mid-air like a torrential rain.

"What...what kind of magic trick is this?!"

Inside the viewing hall, Achuka Beelzebub's glasses shattered with a "crack".

He stared intently at the screen, his whole body trembling violently.

"The system has been taken over?! That's impossible! This is the underlying logic of the Rating Game that I personally wrote! How could it be instantly overwritten by external magic?!"

In the canyon.

Morgan's ruby-like eyes coldly watched the panicked demons in the sky, her beautiful face devoid of any emotion, as if she were simply dusting off her house.

"Showing off magic tricks in front of me?"

"Overestimating one's abilities."

Morgan slowly closed his five fingers.

"—Fairy Magic: Absolute Erasure (Concept Delete)."

Buzz—! ! !

There was no earth-shattering explosion.

There are no fancy lighting or special effects.

The very instant Morgan closed his five fingers.

The remaining eleven high-level demons in mid-air, along with the destruction magic they had already condensed, were wiped off the canvas as if by an invisible eraser.

Starting from the toes, moving to the torso, and then to the head.

It gradually transformed into extremely fine, pale blue specks of light and dissipated into the air.

There were no screams.

Because even the "concept" of making a sound has been completely erased.

"..."

The entire canyon fell into a deathly silence.

From Scáthach's attack to Morgan's snap that ended the battle.

The time on the stopwatch.

Only fifteen seconds had passed.

"How boring."

Scáthach retrieved her magic spear into her spirit base and clapped her hands somewhat listlessly.

Artoria also sheathed her holy sword and obediently retreated behind Luo Chen.

Looking at the empty sky and the demon nobleman on the ground, whose fate was unknown, Luo Chen's lips curled into a satisfied smile.

He raised his head, his gaze seemingly piercing through the barriers of another dimension, directly looking into the viewing hall filled with high-ranking officials of the underworld.

"Did you see that?"

Luo Chen's voice wasn't loud, but after Morgan forcibly seized system permissions, his voice was amplified clearly to every corner of the Underworld.

"This is what I mean by 'giving you three steps'."

"Whether you are demons or gods."

"As long as you stand on the opposite side of me..."

In Luo Chen's crimson-gold vertical pupils, the absolute dominance belonging to the [Two-Digit Full Authority Domain of the Little Garden] transformed into a substantial mental storm at this moment, directly impacting the souls of every spectator through the screen!

"—The only possible ending is to turn into dust."

"Now, do you understand the rules?"

……

The Underworld, the central viewing hall.

Dead silence.

A deathly silence.

Thousands of pure-blooded demons, noble family heads, and representatives from the three major factions sat frozen in their chairs, as if they had been collectively frozen in place.

Fifteen seconds.

Just fifteen seconds.

An elite team of sixteen high-ranking demons was like ants being crushed before this man's three subordinates, with no chance of resistance whatsoever.

Even more terrifying was the woman in black (Morgan).

In an instant, she usurped the alternate dimension system personally constructed by the Demon King Achuka, and in a completely illogical way, conceptually "deleted" the eleven demons!

This is no longer a battle.

This is a declaration to the world that their power is nothing more than a toy that can be crushed at will in front of the other side.

"Thump."

The Phoenix leader, who had previously been a strong advocate for war and clamored to tear Luo Chen apart, now rolled his eyes back and slid off his chair to the ground, with a suspicious puddle of water seeping from his crotch.

He was so scared he wet himself.

Sazex sat in the main seat, his face equally pale, but a hint of relief flashed in his eyes.

"fine……"

He muttered to himself.

"Luckily we went to kneel early yesterday..."

"This kind of monster... even if the entire Earth were blown up, it probably wouldn't even be able to hurt a single hair on its head."

"Achuka".

Sazex turned to look at the chief of technology, who was still sweating profusely.

"Yes, yes..."

"Disconnect the broadcast immediately. Also, write down the names of the families that just went into battle."

Sazex's eyes instantly turned cold.

"Now that lord has demonstrated his power, it's time for us in the Underworld to purge those fools who are oblivious to their own mortality. We absolutely cannot allow their stupidity to jeopardize the survival of the entire world."

……

But in another dimension.

"All done. Well done, ladies."

Luo Chen turned around and naturally put his arm around Morgan's waist, while giving Saber's head a pat with his other hand.

"Let's go back and have afternoon tea."

"I heard that Xiaoyu made a limited edition strawberry parfait today."

"Hmph, you're smart to know what's good for you."

Morgan turned her head away haughtily, but the smile in her eyes was impossible to hide.

"Master, after we return, we'll meet at the training grounds tonight..."

Scáthach leaned close to Luo Chen's ear, her breath sweet as orchids.

As the golden portal opened once more, this "monster tour group," which had so casually crushed the dignity of the underworld, embarked on their journey home amidst laughter and conversation.
