A certain crossover anime's nuclear-powered sword immortal

roar----!!!

A scorching, enormous flame erupted from its mouth, heading towards Shirou!

"It's about the same as hot water..."

With the 'Third Star Particle Body', Shirou's body was already quite strong, so attacks of the level of 'Black Dragon' Nidhogg could not harm him.

However, that alone is not enough. Without sufficiently powerful combat methods, the final situation will be that he cannot completely defeat the enemy, and the enemy cannot completely defeat him either.

If we could project an EX-rank Noble Phantasm, or further upgrade "Unlimited Blade Works", things should change.

As Shirou swung his azure greatsword, a huge wound was cleaved open on the massive body of the 'Black Dragon' Nidhogg.

"It seems your scales aren't enough to protect your body."

Shirou made this sarcastic remark, then continued to swing his greatsword, slicing through the layers of scales covering the black dragon's body and tearing apart its flesh.

"Die here...! Ha!"

Every strike Shirou delivers is a mixture of flesh and blood, his movements brutal and devoid of any elegance, brimming with violent aesthetics.

.

The black dragon's mournful howl sounded like a symphony to Shirou.

The splattered dragon blood stained Shirou's body. If it were his body before he obtained the "Third Star Particle Body," it would probably have been melted by the scalding blood.

"You annoying ant, I will crush you into dust!"

The black dragon, with its strong body, spread its powerful, jet-black wings. In an instant, the flapping of its wings created a whirlwind that lifted the swords on the wasteland. Liliana was not spared either, and she quickly began to chant a spell.

"Wings of Artemis, traverse the night, grant me the privilege of soaring through the heavens!"

"Flying": This is a more powerful magic than "Jumping". It should be said to be a unique magic of witches. It can make the caster fly in the air and stop suddenly during the fall, defying the laws of physics.

Even though she gained the ability to fly through magic, Liliana still struggled against the storm, her small body swaying constantly in the gale.

At that very moment, Shirou was traveling along the back of the black dragon, wielding his azure greatsword that trailed blue shadows, slicing through the black wings and piercing through them.

roar------!!!

With its wings severely damaged, the black dragon roared, its body, which had been hovering in the sky, involuntarily turned to the other side and gradually fell towards the wasteland below.

Then, the moment he looked up, Shirou was stunned by what he saw.

"That is……!?"

The black dragon, which had just been severely injured by Shirou's attack, now showed no signs of injury. The wounds that had been cut by Shirou's azure greatsword had healed completely, as if it had never been hurt at all.

And that's not all. The surface of the black dragon's massive body began to show a molten red color, and its originally black scales gradually turned into a bright red color, as if they had been scorched by flames.

The current Nidhogg is completely different from the poisonous dragon in Norse mythology. At this moment, it is like a lava fire dragon from head to toe, with no trace of blackness left on its body.

The clouds in the sky were also scorched by Nidhogg's change in body, turning into a fiery red color.

In this world of "Unlimited Blade Works," Nidhogg, perched high in the sky, is like a setting sun.

Chapter Seven: The Sword of Destiny

"No... my attack just now should have actually worked. Those wounds and the black dragon's howls were definitely not fake..."

Shirou frowned slightly, as if he had just realized something.

"Could it be that Nidhogg, the 'Black Dragon,' has appeared in the world as a 'Disobedient God,' which is why his appearance is so different from that in mythology?"

Shirou thought about it more and more and felt that his guess was pretty accurate.

In the world of Campione, the gods of the primitive era had neither names nor physical forms.

Humans merely found the form of God in the vast sky and earth, fearing the storms, floods and other disasters brought by God's wrath, and worshipping dangerous and powerful beasts as if they were the incarnations of God.

Humans, who feared the gods and worried that their power was too great and would harm them, used these mythological 'rituals' to limit the gods' power.

The gods use thunder, so some people call them the God of Thunder, rather than the god having the power of thunder because of a legend that a certain person is the God of Thunder.

A god whose name and myth have been woven into his being will not do anything beyond those two things.

As the primitive era ended, in this modern age, some gods began to break free from the constraints of myths created by humankind and returned to their primitive state.

Such a god is called a 'disobedient god'.

They defy the myths woven by humankind, breaking free from their constraints and wielding their power recklessly. Even unintentionally, their immense power can bring great disasters to humanity.

If the sun god were to descend, the entire world would be transformed into purgatory.

If the god of the ocean were to descend, the entire world would be swallowed by the waves and silenced at the bottom of the sea.

If Thor were to descend, the entire world would be filled with thunder.

A god who creates his own posture according to his own preferences and brings disaster is a 'disobedient god'!

At this moment, Nidhogg, the 'Black Dragon of Disobedience,' finally revealed its true power after being severely injured by Shirou's azure greatsword.

"This state... is just like a boss in a game that has been reduced to a certain amount of health and then enters a more ferocious and violent second phase."

While muttering to himself with amusement, Shirou's azure greatsword vanished as it turned into pale blue specks of light.

Immediately afterwards, a large amount of blue light appeared in the sky behind Shirou, and one Noble Phantasm after another was constructed.

"Since you've done your best, I can't just sit here and wait to die."

As the shapes of tens of thousands of Noble Phantasms were completed, the 'swords' that filled the sky glowed with a blue magical light.

From a distance, it looks like a giant blue wall.

It has to be said that "Unlimited Blade Works" is very similar to "Gate of Babylon" in some ways.

One is a replica of the original Noble Phantasm, while the other is a copy that is a grade lower.

Of course, some advantages of "Unlimited Blade Works" are unmatched by "Gate of Babylon". For example, whenever Shirou holds a copied "sword", he can extract corresponding combat experience from that Noble Phantasm.

Then there are the Noble Phantasms in "Unlimited Blade Works," none of which are unique, because they are copies that can be easily projected, so Shirou can use them without any hesitation.

At this moment, every 'sword' within that colossal blue wall that stretched to the sky revealed its unique sharpness.

Shirou had tried this method before, and although it could cause great damage to the black dragon Nidhogg, it could not kill him.

Therefore, he is no longer projecting Noble Phantasms as casually as before, only caring about their level and ignoring their characteristics.

The Noble Phantasms that Shirou is projecting now are the legendary dragon-slaying swords—"Balmung"!

This sword is the magical sword wielded by Sigurd, the greatest hero of the Norse, in the Volsunga Saga, symbolizing both honor and destruction.

At the same time, this sword is also the prototype of the 'Sword in the Stone' in the Arthurian legend. Just as the 'Sword in the Stone' is a sword of destiny stuck in a stone, the 'Balmung' is also a sword of destiny stuck in the tree of King Balseng.

In legend, the wielder of this demonic sword "Gram" was a hero named Sigurd, whose story is filled with honor and destruction.

Sigurd inherited fragments of the sword from his father and then reforged it into the "Balmung," making it a legendary magic sword capable of killing even dragons.

This is the strongest demonic sword, comparable to the strongest holy sword, and also possesses the ability to slay dragons.

And now, this Noble Phantasm is naturally the most suitable one for Shirou to project.

"Full projection, maximum power—fire!"

At Shirou's voice, all the swords within the giant blue wall seemed to be summoned, rushing out and leaving countless blue trails in the air, like falling meteors.

Nidhogg's massive, fiery red body, now resembling molten lava, was like a motionless target under the projectiles of those 'swords,' which easily pierced his body.

This time, unlike the previous times when Shirou projected 'swords' that pierced the black dragon Nidhogg, even though those 'swords' were no different in size from toothpicks to Nidhogg, the projected swords were now Noble Phantasms with dragon-slaying properties. So, the Noble Phantasms' properties had already taken effect just by piercing the black dragon's body.

With an attack of three or four thousand Noble Phantasms, even if these 'swords' were as thin as toothpicks to the Black Dragon Nidhogg, they could still pierce him to death.

At this moment, the black dragon Nidhogg was covered in swords, and he could no longer be seen as a dragon.

"Roar----!!!"

Because the dragon-slaying properties of those thousands of swords were activated simultaneously, it was as if the 'swords' embedded in Nidhogg's body were all poisoned enough to cause him pain, causing him to let out a roar that was a mixture of pain and rage.

At that moment, Shirou's right hand was already pointing towards the black dragon whose entire body was covered with 'swords', and then he suddenly gripped it tightly.

"Fantasy Collapse!"

As the swords began to crumble, massive amounts of magical power surged forth from them. With thousands of these magical weapons releasing their violent power simultaneously, thick white smoke began to rise from the black dragon's body in the very first instant.

That was the fusion of blood and fire, ultimately turning into steam.

Finally, as the swords shattered, they burst forth with an incomparably dazzling azure light, and the black dragon Nidhogg's body, which had entered the second stage and was as translucent and fiery red as magma, was continuously subjected to the baptism of explosions.

Countless pieces of flesh and blood exploded in all directions. The deafening explosion created a shockwave that even created a huge hole in the clouds in the sky. The clear blue sky was suddenly empty without the cover of clouds!

This was the first time Shirou had unleashed "Imagine Collapse" with all his might since obtaining the "Third Star Particle Body," and the resulting explosion even caused the entire space to tremble violently.

As if the heavens and earth were about to shatter, Shirou heard the voice of Nidhogg, the black dragon whose body had perished, just as the world was breaking apart.

"You are quite good... human, you are indeed worthy of my power!"

Before Shirou could even ponder the meaning of those words, his consciousness was completely severed from reality.

The spirit seemed to be passing through a tunnel, and when Shirou opened his eyes, he saw a pure white world.

Suddenly, a cute voice with a hint of coquettishness entered Shirou's ears, a voice that felt like a gentle hand caressing his head.

The cover made him feel that his consciousness had become incredibly clear.

"Oh, you're awake!"

Chapter Eight: The Ritual of Pandora

As Shirou's consciousness entered the Netherworld, a girl named Erica Brontë arrived at the periphery of the Colosseum, on Via Flaminia.

"What on earth happened over there?"

The girl had pale purple eyes and wore a gothic dress as vibrant as red wine. Her long, flowing golden hair danced freely behind her as she walked, radiating a captivating glow in the sunlight.

Compared to most of her peers, Erica is undoubtedly far more outstanding. Not only has she reached the rank of Grand Knight at such a young age, but her strength is also among the top of all witches. Furthermore, because of her exceptional strength, she is feared by many magicians as the 'Crimson Demon'.

Just yesterday, Erica received news that Liliana had gone to Rome, which puzzled her greatly.

Liliana, who had been on a magical vacation in London, Italy, suddenly went to Naples, Italy, and then rushed to Rome without stopping. Given Liliana's personality, something very important must have happened in Rome, which is why she was in such a hurry.

As a friend and rival, Erica naturally keeps a close eye on Liliana's condition and movements.

Although they have a good relationship, their magic societies are two opposing ones, so she still hopes to surpass Liliana and place her magic society in a higher position.

However, the very next day, when Erica arrived in Rome, she happened to see the black dragon that blotted out the sky, which was undoubtedly the largest monster she had ever seen in her life.
