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

In 1783, on the front lines of the Western Front in North America.

This is a real meat grinder.

The earth was shattered by countless magical bombardments, and the remains of Edison's mechanized infantry were piled up with the corpses of Celtic warriors, emitting a suffocating stench.

"Kill! For Queen Medb! For the Mad King!"

Tens of thousands of Celtic warriors, clad in leather armor and wielding crude weapons, charged toward the last remaining defensive line like tireless zombies, howling as they went.

They are mass-produced soldiers enhanced by the Holy Grail, incapable of pain or fear.

Before that crumbling defensive line, only a golden figure still stood.

"Brahma, cover the earth."

A clear, low murmur arose.

boom!

Golden flames erupted instantly, burning the hundreds of enemies at the forefront to ashes.

Lancer, Karna.

"Is the quantity... endless?"

Karna, slightly out of breath, swept his God-Slaying Spear across the room once more, forcing back a wave of attacks.

As a top-tier Heroic Spirit, it can easily handle even enemy forces.

But the enemies on this battlefield seemed endless, and he also had to be distracted by protecting the vulnerable soldiers and wounded behind him.

This is a pure war of attrition, and that is precisely the tactic of the Mad King Cú Chulainn—to wear down the sun's brilliance with the flesh and blood of his minions.

"Mr. Lancer! Let's retreat! We can't hold this place!"

The communications soldier in the rear shouted in despair.

"No."

Karna shook his head, his back a solitary figure.

"If I retreat, the defenses here will collapse, and more people will die."

"Having accepted the president's commission, I will fight to the last moment."

"What a foolish yet dazzling persistence."

Just as Karna was about to unleash his Noble Phantasm to clear the area.

A voice, tinged with a hint of mockery, abruptly pierced through the clamor of the battlefield, exploding directly in his ears.

Karna's movements suddenly froze.

That voice...?

Why does an uncontrollable throbbing sensation arise from the depths of my soul when I've never heard of it before?

"However, I'll take over the battlefield from here on out."

Om-! ! !

The sky suddenly changed color.

The originally dim yellow sandstorm was forcibly torn apart by a domineering crimson wind pressure.

A figure descended from the sky, falling straight down in front of Karna like a meteorite.

Boom!

The earthquake trembled.

Centered on the point of impact, a visible crimson-gold aura radiated outwards in a ring. The Celtic warriors who were howling and charging forward were instantly crushed into dust by the terrifying magical power the moment they came into contact with this aura, before they even had time to scream!

The smoke and dust cleared.

Luo Chen stood before Karna, one hand in his pocket and the other casually holding the Holy Sword.

He didn't turn around, but simply looked calmly at the densely packed enemy troops ahead.

"Yo, Son of the Sun."

Luo Chen turned his head, a hint of a smile in his crimson-gold vertical pupils:

"He looks a little disheveled. This isn't like the man I know... the one who could go toe-to-toe with me."

Karna was stunned.

He looked at the figure in front of him from behind.

Short golden hair, pale silver armor, and that aura of a red dragon emanating from the inner sea of ​​the star, hotter than the sun.

I have no memory of this person.

This was the first time he had seen this heroic spirit.

but……

Boom!Boom!

Karna's heart was pounding, and his spirit origin was trembling.

It was a sense of familiarity etched deep in one's soul, even... awe.

In some distant time and space, they once fought a desperate battle where everything was at stake, and... he lost.

"Who are you?"

Karna's voice had taken on a barely perceptible hoarseness.

You can call me Luo Chen.

Luo Chen turned around, but did not give a detailed answer.

He looked ahead at the Celtic army that had paused temporarily because of his appearance, but then surged forward even more frantically.

"What a bunch of clueless scum."

Luo Chen's eyes turned cold, and he casually waved his hand, which was holding the Holy Sword and imbued with the Wind King Barrier.

It wasn't just wind pressure, but a high-density sword aura infused with the magic power of the Crimson Dragon.

Rumble, rumble, rumble—!

A golden storm, hundreds of meters wide and several kilometers long, swept out.

This is not swordsmanship; this is a natural disaster.

Where the storm passed, deep furrows were plowed into the earth, and thousands of Celtic warriors were instantly swept into them, shredded into their most primordial magical particles.

The once dark and gloomy battlefield was instantly cleared of more than half by this sword strike.

All that remained was a desolate, scorched wasteland.

"this……"

The United States soldiers behind them stared wide-eyed, not even noticing that their guns had fallen from their hands.

How could a mere casual sword strike achieve such a feat?!

"So...so strong..."

Ritsuka and Mashu, who had just arrived, lay on the hillside, looking at the exaggerated results of the battle. Although they had seen it many times before, they still couldn't help but swallow hard.

"Hmph, a show-off."

Morgan stood on high ground, elegantly sheathing her magic gun. She was clearly somewhat dissatisfied that Luo Chen had stolen the limelight, but the pride in her eyes was impossible to hide.

In the center of the battlefield.

Karna looked at the terrifying sword mark, and a hint of emotion finally appeared on his indifferent face.

"This power... has far surpassed the standards of a Servant."

He looked at Luo Chen, the wariness in his eyes gradually dissipating, replaced by an acceptance of someone of a higher status:

"Although I don't remember ever seeing you before."

"But my gun tells me... you are an opponent worth fighting for."

"And...trustworthy allies."

"My intuition is correct."

Luo Chen sheathed his sword, walked up to Karna, and patted his shoulder, which was still warm from the heat, as if he were an old friend.

"Although you in this world don't have that memory, that doesn't prevent us from cooperating."

Luo Chen pointed north, which was the direction of the Celtic base camp:

"Let's go together and smash that so-called 'Mad King' and that queen who wants to conquer the world... along with their thrones."

Karna was taken aback.

Then, this usually expressionless hero of charity smiled faintly.

"learn."

"If I were with you... perhaps this endless war could truly come to an end."

Just then, a purple phantom appeared beside them.

Scáthach held two pistols, her wine-red eyes fixed on the distant horizon, a twisted expectation burning within them:

"Is our reminiscing over, Master?"

"I smell... the scent of that good-for-nothing disciple."

"Cú Chulainn..."

The Queen of the Land of Shadows' smile was chilling:

"I can't wait to teach him a lesson."

Luo Chen looked at his teammates, whose fighting spirit was off the charts, and nodded in satisfaction.

The Knights of the Round Table, the Fairy Queen, the Master of the Land of Shadows, and Karna, the Son of the Sun.

This configuration...

Mad King Cú Chulainn, I hope you can hold on for a few more seconds.
