A certain crossover anime's nuclear-powered sword immortal

Upon witnessing this scene, Rama finally sensed something was wrong.

He sensed that Shirou's magical power seemed inexhaustible. Even though he had just used such a powerful divine weapon, he seemed to be seamlessly transitioning to the next divine weapon to continue the attack without any depletion.

We can't let him continue like this!

Even Rama felt a sense of crisis and quickly raised the "Savior Blade" in his hand.

A dazzling white-gold light immediately shone from the blade.

"O divine blade of salvation, now reveal your true form to the world!"

"The Last King," Rama said softly, holding his beloved sword.

At that moment, under the pitch-black night sky, the platinum-gold light shone brilliantly.

A vast and astonishing magical power filled the entire body of the 'Last King'.

Then, a huge square magic cube appeared above his head.

The square magic cube, about ten meters on each side, is divided into small grids, each grid depicting a weapon.

If you were to count them, you could probably identify hundreds of weapons and equipment.

The most numerous were 'arrows'. In addition, there were swords, knives, bows, spears, axes, shields, clubs, naginatas, lances, iron balls, ring-shaped objects, brick-like blocks, and so on, even things that could hardly be called weapons.

The geometric patterns depict a Japanese magic square array of dozens or hundreds of gods and Buddhas.

This is a mandala composed of countless weapons instead of gods and Buddhas as its main elements.

"It's finally done, the ultimate sword to annihilate all demon lords..."

Seeing this, Guinevere couldn't help but murmur aloud.

"Demon lords, the upgrading of this sword signifies your demise."

It was a tone that did not boast of its own power at all, and was so indifferent that it even sounded transactional.

"When I was first born into this world, I was gifted countless celestial weapons each time I completed a mission to defeat the Demon King. The 'Savior Blade' is the embodiment of all of these weapons. Therefore, this can be considered my true form."

As he said this, a golden longbow formed from lightning appeared in Rama's left hand. As he drew the bowstring, lightning gathered and eventually transformed into a straight arrow.

"Let's see if you can withstand this attack, the strongest demon king in the world!"

In mythology, Rama is a hero who uses a bow and arrow.

Moreover, as if confirming the truth of this myth, the earth began to shake.

Simply picking up the bow triggered an earthquake.

At this moment, the 'Last King' actually closed his eyes.

However, I did not lose my sense of sight.

That's cunning!

"It is said that in ancient times, there was a hero in the Eastern Kingdom who shot down nine suns. The arrows he shot disappeared with the falling suns. However, a celestial craftsman who recreated his great feat made a pair of bows and arrows."

The hero who annihilated the demon king raised his longbow with his left hand and aimed the arrow at Shirou's body.

"This is merely a forgery, not a bow and arrow powerful enough to shoot down the sun. However, it can still exert tremendous power when released onto the ground... Let's begin with this level of power."

With those words, a golden arrow shot out suddenly, tearing through the air and unleashing a burst of violent lightning.

The countless bolts of lightning unleashed a furious barrage alongside the arrows, their power shaking heaven and earth.

Without further hesitation, Shirou unleashed Excalibur.

That magnificent star-forged holy sword, which resembled the most exquisite work of art, now shone with the most dazzling light in the world.

"Ex----calibur!!"

Shirou raised the holy sword high above his head; the sword itself had shattered and transformed into a pure white pillar of light, which poured down towards Rama, the 'Last King' below!

"It's not over yet!"

Shirou allowed the magical power to be unleashed by the holy sword in his hand, while also releasing the divine artifacts that were suspended in the air behind him.

Gold, red, white, purple, blue... all sorts of dazzling colors shone in the sky, and the power unleashed by the divine artifacts left the surrounding demon kings and disobedient gods speechless with shock.

This time, Shirou had unleashed the maximum number of divine artifacts he could, and the sheer amount of magical power far exceeded all the energy that the blue planet beneath his feet could generate.

Once all these divine artifacts are unleashed, they possess enough power to destroy a star.

Therefore, Shirou did not dare to unleash it in the real world. While releasing the divine weapon, he also directly activated "Unlimited Blade Works".

The sea, islands, sky... everything vanished into nothingness at that moment, and the Demon King and the disobedient gods all fell down.

White clouds drifted across the sky, and orange sunlight shone on the earth.

The ground was a wasteland filled with upside-down swords, stretching as far as the eye could see, with nothing but swords.

"Where...is this place...?" Mrs. Aisha looked around nervously.

“A world of its own? What a wonderful space…” Anne Charlton murmured.

"This is also Orihara Shi"

"Lang's power? He can actually transfer us to another space..."

Alexander Gascoigne, the "Black Prince," looked at the world with some surprise.

Meanwhile, the other four god-slayers were also curiously examining this wasteland.

"This guy really loves swords, he actually has so many hidden away..." Luo Hao sighed as he looked at the endless swords stretching across the wasteland.

Each of those swords, each with its own unique shape, contains immense magical power and would be considered a rare and divine weapon in the outside world.

Not to mention that many divine artifacts were also placed here, which made them gasp in astonishment.

At this very moment, the divine artifacts that Shirou had unleashed, illuminating the heavens and earth, finally erupted completely.

In that instant, the wasteland was filled with all sorts of dazzling lights, and the power released by those divine artifacts crisscrossed and then clashed with the divine artifacts of the 'Last King' Rama.

This place has been transformed into the purest battleground, where forces continuously clash and suppress each other.

That is a beauty and miracle that mortals cannot touch or witness, because even the simplest collision between these two forces is enough to annihilate the world and leave all things desolate.

In the end, Shirou had a slight advantage, because he was not born into this world, and the gods' 'covenant law' could not apply all the rules to him.

Amidst the grand spectacle of their epic battle, cracks began to appear in this space, gradually disintegrating.

The sound of space shattering and the sound of the demonic sword "Twilight" piercing Rama's chest rang out together, shaking everyone's hearts.

"Uh-huh——"

Rama lowered his head and looked at the demonic sword that was rapidly absorbing the power of the gods within him. The usual weariness in his eyes gradually eased.

Can I finally rest?

The Last King murmured this to himself.

Then, the pale-faced hero cast a gentle gaze at the demon king before him.

"I am extremely grateful..."

Chapter 1: Return of Fuyuki City

The moment Shirou absorbed the power of the gods possessed by Rama, the 'Last King', the ground began to tremble, and the world changed drastically.

Earthquakes trembled, tsunamis struck, gales howled, volcanoes erupted... all sorts of natural disasters seemed to have suddenly reached their peak and began to erupt one after another.

But this was merely the gods' last struggle; the phenomenon lasted for less than a minute before gradually fading away.

Having acquired the power of the gods, Shirou's strength has reached a level that no 'godslayer' throughout history could ever hope to achieve.

Destroying stars is also an easy task.

"It's finally over..."

Shirou felt an unprecedented sense of relief as the world finally came to an end in his own hands.

The sky cleared, the warm sun shone, and a gentle breeze brushed against his body, stirring the hem of his clothes.

……

On his return journey, Salvatore Tony had just run back when he learned that the 'Last King' had been defeated, and he was immediately distressed.

"No way! I just thought of a new move...!"

The other demon lords ignored the 'Sword King' who was acting like a child, while Luo Hao looked at Shirou.

"It seems you've reached a level that even I find difficult to match, but I won't stop there. If you become complacent because of this, be careful I don't overtake you!"

"Then I'll wait and see."

Shirou smiled.

After Shirou displayed overwhelming power, the other Demon Lords became much more 'polite' towards him, chatting with him for a while before leaving one after another.

After leaving these demon kings, Shirou returned to Japan and told Erica and the others what had happened.

The three witches listened as Shirou recounted the power of the 'Last King' Rama, and were awestruck by the magnificent scene of their 'King' battling that hero.

After spending some time with them, Shirou decided to leave.

Due to his increased strength, Shirou is now able to control this world. After he leaves, time in this world is frozen by him and will not be unfrozen until his next visit.

[Main Quest "Defeat the Last King" Completed! One chance to obtain a Dimensional Roulette!]

As the system notification sounded in his mind, Shirou let out a slight breath.

"Next... it's time to go back and fulfill my promise."

As he murmured this, Shirou's body transformed into light and traversed the world.

The date of the trip was February 1, 2004!

……

As if illuminated by a light, when Shirou opened his eyes again, his vision shifted to that familiar room.

The layout hasn't changed much, but it's regularly maintained, so it's kept spotless.

While Shirou was away in other worlds, Irisviel must have come here specifically to help him clean up the mess, and perhaps even hinted at it to the Orihara couple.

A ten-year gap,

Of course, it was impossible for her parents to know, so Irisviel used magic to temporarily make them forget Shirou's existence.
