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

Einzbern Castle, front courtyard.

As the barrier shattered, a piercing alarm activated the defense system dormant beneath the snowfield.

The earthquake trembled, and the accumulated snow collapsed.

Dozens of enormous alchemical golems, constructed of rock and steel, burst from the ground. They were over five meters tall and their bodies were inscribed with enhanced magical spells.

A red light flickered in its hollow eye sockets as it took heavy steps toward the intruder.

Meanwhile, countless combat androids dressed as maids and wielding halberds or magical costumes poured out from the castle's corridors and firing ports.

They were expressionless, like a group of soulless killing machines.

"Is this how Einzbern hosts his guests?"

Irisviel looked at her "sisters" and golems who had once protected this place but now wanted to kill her, and a trace of pity flashed in her eyes.

"Hmph, just a pile of garbage."

Morgan didn't even bother to lift her magic spear; an opponent of this caliber wasn't even worthy of her wasting her magic.

"Since it's the front line, leave it to me."

Artoria stepped forward and stood in front of the crowd.

She wasn't wearing armor; her blue modern dress looked rather thin in the wind and snow, but the invisible sword in her hand stirred up a violent current of air.

"I've always fought as my Master's sword, but this time..."

Artoria glanced back at Irisviel, a stern smile on her face:

"I wield my sword to protect my family's happiness!"

boom!

Her petite figure vanished instantly.

The next second, the rock golem at the very front exploded!

It was shattered from the inside by the pressure of the sword that carried the [Wind King Barrier].

Artoria moved through the golems like a blue lightning bolt.

boom! boom! boom!

Every swing of the sword is accompanied by the destruction of a war machine.

Those hard alloys were far too fragile in front of her.

As for the android maids who rushed at her, Artoria simply knocked them unconscious with the back of her knife or by pressing down on them with her sword, without killing them—she knew that would hurt Irisviel.

In less than a minute.

The once densely packed defensive lines have been forcibly breached, creating a clear path leading to the castle gate.

The ground was littered with broken stones and maids lying motionless on the ground.

"So...so powerful," Irisviel exclaimed. Is this the Knight King who has completely broken free from the constraints of body and mind?

"Let's go."

Luo Chen, holding Morgan's hand, strolled towards the tightly closed black iron gate, stepping over the remains of the golem as if taking a walk in his own backyard.

……

In the castle hall, during the audience.

Yubstakuhaid von Einzbern (Ahad), the current patriarch of the Einzbern family, stood on the high platform, his face ashen as he watched the images transmitted through the monitoring spell.

"A failed attempt... actually returned with outsiders?"

Ahad gripped the scepter tightly, his eyes filled with disbelief and rage.

The homunculus that served as the vessel for the Holy Grail not only failed to fulfill its duty to die, but also colluded with Servants to launch a counterattack against its own clan.

This is an unprecedented disgrace in Einzbern's thousand-year history!

"Since that's the case, then don't blame me for being ruthless."

A ruthless glint flashed in Ahad's eyes. He looked toward the corner of the hall, where a little girl with silver hair and red eyes sat.

Illyasviel von Einzbern was only eight years old.

She was huddled in a chair, hugging her knees, her eyes vacant and filled with fear.

Boom! ...

With a deafening roar, the heavy black iron gate was blasted away by the violent magic, crashing heavily into the center of the hall and kicking up clouds of dust.

As the smoke and dust cleared, four figures stood against the light.

"Nice to meet you, or rather... farewell, old man."

Luo Chen walked at the front, his gaze passing over Ahad and immediately locking onto Ilya in the corner.

Fortunately, although she looked a little haggard, she was not injured.

"Irisviel!!"

Ahad let out a roar that echoed through the empty hall:

"You traitor! Have you forgotten the purpose for which you were created? How dare you bring outsiders to defile this sacred magic workshop!"

"And you... mere Heroic Spirits, nothing more than familiars of magicians, how dare you draw your swords against the Einzbern family?!"

Faced with this millennium of accumulated power.

Irisviel's body trembled instinctively.

But the next second, a warm hand grasped hers.

Luo Chen stood beside her, his eyes coldly fixed on the old man on the platform:

"Old man, your voice is too loud."

"Also, figure out the current situation."

"Standing before you is not your familiar, but the conqueror of the Fourth Holy Grail War, and..."

Luo Chen pointed to Morgan and Saber beside him:

"Two true kings."

"A king? Ridiculous! Before the miracle of the Third Law, even a king is but a sacrifice!"

Ahad suddenly raised his scepter, and the magical loops throughout the castle were instantly activated.

As the patriarch, he has the authority to control all the androids within the castle, including Ilya!

"Ilya! Kill them!"

Ahad issued a cruel order.

He planned to use the massive magical circuit within Ilya's body as a human bomb to attack Luo Chen and the others.

"ah……!"

Ilya let out a painful scream, the light in her red eyes vanished instantly, and her body involuntarily floated up, as terrifying magic began to gather around her.

"Ilya! No!!" Irisviel cried out in heart-wrenching despair.

"court death."

Luo Chen's eyes turned completely cold.

Using children as weapons has crossed his bottom line.

"Morgan," Luo Chen called out in a low voice.

"understood."

A red glint flashed in Morgan's eyes.

【Fairy Magic - Forced Intervention】.

It's not a confrontation, but a higher-dimensional "authority tampering".

As a queen who manipulates magic with ease, this alchemical control circuit seems ridiculously rudimentary to her.

"Break it...!"

Morgan made a grabbing motion in the void.

Ilya, who was originally floating in the air, suddenly lost all her violent magic power and fell from the height.

"Saber!"

Luo Chen shouted.

Artoria transformed into a blur and caught Illya before she hit the ground.

"No... Impossible! Einzbern's spell..." Ahad watched this scene in horror.

"Your era has ended, you old alchemist."

Luo Chen's figure had appeared on the high platform at some point, standing in front of Ahad.

He reached out and grabbed Ahad by the neck, lifting him into the air.

"You... what do you want to do... I am from Einzbern..." Ahad struggled desperately, but the hand was like an iron clamp, not moving an inch.

I don't care who you are.

Luo Chen moved closer to his face, his crimson dragon eyes burning with flames of destruction:

"All I know is that you want to hurt Ilya. So, please die."

Click.

Luo Chen crushed Ahad's throat and injected a massive amount of crimson dragon magic into his body, completely destroying his core functions as an artificial human.

Ahad's eyes widened as his body rapidly turned gray and withered, eventually turning into a pile of useless alchemical residue scattered on the ground.

The will that had ruled Einzbern for centuries thus perished.

"Ilya..."

Irisviel rushed over, took the still somewhat bewildered Illya from Saber's arms, and held her tightly in her embrace, tears streaming down her face.

"It's alright... Mom's here... It's alright..."

"Mother……?"

Ilya stared blankly at the warm embrace before her, feeling that familiar pulse of blood, and her previously empty eyes gradually regained focus.

"Mom...you're back?"

"Waaaaaahhhhhh!!"

The little girl finally let go of all her strength and fear, and cried loudly in her mother's arms.

Luo Chen stood on the high platform, looking down at the mother and daughter who were embracing and crying, and Artoria who was silently guarding them with slightly red eyes.

He turned around and looked at Morgan beside him.

"What? Not going to start tearing the house down?" Luo Chen asked with a smile.

"I'm not interested anymore."

Morgan looked at the pile of old man's remains and disgustedly flicked his handkerchief away.

"This castle, which reeks of decay, is so dirty that it would be too filthy to even dismantle."

"but……"

Morgan looked down at Ilya, a rare hint of tenderness flashing in his eyes:

"Since she's the little brat you're going to raise, then I'll reluctantly admit she's an illegitimate princess. As long as she doesn't steal my food like that lion."

"Don't worry, Ilya is very well-behaved."

Luo Chen jumped down from the platform and walked to the mother and daughter.

Ilya raised her teary-eyed face and looked at the older brother who had just killed the "terrible grandfather" but was now smiling gently.

"Who are you?"

"I?"

Luo Chen knelt down, wiped away the tears on Ilya's face, and revealed a bright smile:

"I am the knight who brought your mother back."

"From today onwards, I am also your... new guardian."

"Come on, Ilya. I'll take you to a new home where there's no cold, no magical experiments, only a warm fireplace and delicious pudding."

Ilya paused, looked at her mother, and saw Irisviel nod with tears in her eyes.

She carefully reached out her small hand and grasped Luo Chen's large hand.

It's very warm.

It was warmer than any hearth in Einzbern.

"Um!"

[Ding! Mission 'Reclaim Ilya' completed.]

The wind and snow continued to howl outside the castle.

But the departing figures of this group burned brighter than any flame.

The regrets of the Fourth Holy Grail War came to a complete end at this moment.
