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

【Vain's Sky Garden】, interior corridors.

This is a maze that defies the laws of physics.

Huge stone pillars support a dome that has no visible top, black water flows along the surrounding walls, and the air is filled with a cloyingly sweet aroma.

"Cough...cough cough!"

Joan of Arc, who was walking at the back, suddenly covered her mouth and nose, swayed, and her face instantly turned an unnatural flush.

As a Ruler, she possessed extremely high magical resistance, but at this moment she felt short of breath, as if her lungs were on fire.

"This is... Sidra's poison?" Joan of Arc's voice was hoarse.

"It's not just Sidella."

Luo Chen, who was walking at the front, stopped and remained calm.

The red dragon heart inside his body was beating at a domineering frequency, instantly burning away all the toxins that tried to invade his body.

"This is an elevation of Semiramis's concept as 'the world's oldest poisoner.' In this garden, the air, magic, and even gravity are all highly toxic."

"That's really low-class."

Morgan, who had been holding Luo Chen's arm, stopped.

She looked at the walls around her, covered in cuneiform script, as if they were piles of garbage.

"So-called poison is nothing more than a clumsy branch of 'transformation' and 'destruction' in magic."

Morgan released his grip and took a step forward.

She gently raised her hands, which were covered in black lace gloves, and snapped her fingers.

Snapped.

Centered on her, a dark blue halo instantly spread out.

Where the blue halo swept, the purplish-black poison gas was instantly neutralized, and the sweet fragrance dissipated, replaced by a crisp, clear air as if from a snow-capped mountain.

"Phew..." Joan of Arc took a deep breath of fresh air, and the burning sensation disappeared.

She watched Morgan's retreating figure with a complex expression.

Although this woman has a nasty, sharp-tongued, and arrogant personality, her magical skills are indeed at a divine level.

"Let's go."

Morgan withdrew his hand, not even bothering to glance at the purified environment around him.

"Don't let those third-rate tricks waste our precious time."

……

Passing through the highly poisonous corridor, you enter a spacious circular hall.

There are no superfluous decorations here, only neatly laid stone slabs on the ground and a huge courtyard that stretches straight to the sky above.

Sunlight—or rather, magically simulated sunlight—was streaming vertically down from the atrium, illuminating the figure in the center of the hall.

He had his back to the crowd, clad in golden armor, his white cloak billowing even without wind.

He held a spear powerful enough to kill gods, and his body radiated intense heat.

Karna, the Red Lancer.

Hearing footsteps, he slowly turned around.

Those indifferent eyes swept over Luo Chen and his group, finally settling on Luo Chen.

"You've arrived."

Karna's voice was calm, devoid of hatred or murderous intent, only the solemnity of fulfilling his duty:

"While I want to commend you for breaking through the outer defenses, my Master is inside making final preparations to save all of humanity."

"This road is blocked."

"To save all of humanity?"

Artoria, wielding an invisible sword, stepped forward, her eyes sharp and resolute.

"If this vain desire is to be fulfilled by seizing the Greater Grail, then I must stop it."

Whether something is false or not is not determined by words, but by power.

Karna raised his spear slightly, the tip pointing towards the ground.

boom!

With just a starting move, golden flames exploded outwards from him, turning the entire hall into a furnace.

"Who's coming?"

Karna asked.

His gaze shifted between Luo Chen, Melusin, and Artoria.

"Whether it's just one person or all of you coming at me, I don't care."

"Such arrogance."

Melsin hovered in mid-air, her dragon wings unfurled, and the cannons hummed: "Master, let me blast him to smithereens. He got away last time, but he won't have a chance this time."

"No, Melusin, you have other tasks."

Luo Chen reached out and stopped the restless fairy knight.

He looked at Karna, a hint of admiration flashing in his eyes.

As a hero of charity, Karna's power is all-encompassing.

Although Melusin has fierce firepower, it would be troublesome if she were to get close in this enclosed space.

"Saber".

Luo Chen turned to look at Artoria beside him.

"This battle is yours."

"As I wish, Master."

Artoria revealed a warrior's smile.

She took a step forward, her blue battle dress fluttering in the heat, her petite figure radiating a formidable aura that rivaled even the sun.

"It is an honor for a knight to fight against the legendary heroes who bestow their favors."

Artoria gripped her sword with both hands, her gaze fixed intently on Karna:

"Before this, I had imagined our duel countless times. Today, I can finally use my sword to confirm our beliefs."

"Oh?"

Karna looked at the spirited knight king before him, a hint of admiration flashing in his previously indifferent eyes:

"Not bad eyesight. No wonder he's King Arthur of Britain."

"Since the king himself has taken to the field, I must return the courtesy accordingly."

"Go, Luo Chen."

Artoria had her back to Luo Chen, her voice firm and confident:

"Leave this to me. Neither the sun nor the raging fire can cross the line of my sword."

She gently pressed the scabbard at her waist—[Avalon].

That was absolute confidence, and a declaration of certain victory.

"I trust you."

Luo Chen didn't hesitate at all.

He took Morgan's hand and led Melissa and Joan of Arc around the side of the battlefield.

Karna did not stop him.

As a hero, having accepted the Knight King's challenge, he would no longer be distracted by attacking others.

This is the pride of the strong.

"Alright, let's begin."

Karna's golden armor shone brightly, and his magic (fire) was at full power.

"Brahma, cover the earth!"

"Strike Air!"

Boom! ...

Golden flames collided with a raging hurricane behind them, and the massive shockwave shook the entire Sky Garden.

But Luo Chen didn't even turn his head.

He knew that Artoria, who possessed Avalon, would never lose.

Passing through the hall, you'll find yourself facing a massive obsidian door.

The door was engraved with intricate spells, radiating a chilling magical aura.

"arrive."

Luo Chen stopped in front of the door.

This is the heart of Vainglory's Hanging Gardens—the Throne Room.

It is also the place where Empress Semiramis and Amakusa Shiro are located.

Morgan.

Luo Chen glanced at his wife beside him.

"understood."

Morgan's lips curled into a cruel smile.

She had long disliked this empress who piled stones to the sky.

"Let me do the rough work of opening the door."

Morgan raised the magic gun in his hand, and black magic gathered into a dense sphere of gravity.

"—Smash it to pieces."

boom!

The obsidian door, which was said to have A-level defense, along with the walls around the door frame, was twisted and collapsed by gravity in an instant, and finally exploded into a pile of debris.

The scene inside the main hall came into view.

On the towering throne, Semiramis held a wine cup, staring in astonishment at the doorway.

Before the Holy Grail altar, Amakusa Shiro Tokisada slowly turned around, a saintly smile on his face that seemed to encompass everything yet was unpleasant to behold.

"Nice to meet you, Master of the Red Team."

Luo Chen stepped into the main hall on the gravel, his cloak fluttering in the dust behind him.

He glanced around, his gaze finally settling on Amakusa Shiro, and the red dragon's vertical pupils contracted slightly:

"Your dream of salvation should end."
