A certain crossover anime's nuclear-powered sword immortal

The immense magical power contained within the sword broke free of its restraints at this moment, unleashing its full power and engulfing everything around it!

Boom boom boom————!!!

This time, even Hephaestus could not ignore it. He looked up in surprise and then immediately slammed his iron hammer into the ground.

The heavy blow shook the earth, causing the ground to crack open, from which endless earth fire spewed forth.

Under the frenzied baptism of these subterranean flames, the powerful shockwaves generated by the magical artifacts that had been unleashed were also engulfed by the flames.

Hephaestus emerged unscathed from the encirclement of the metal beings.

But all the metal figures were destroyed as a result.

After the thick smoke dissipated, Hephaestus looked at his broken metal figures and immediately showed a furious expression.

“Foolish mortals, how dare you destroy what I have created!”

Hephaestus's face flushed red with anger, and he was panting heavily, his beard fluttering wildly.

He then placed the weapon on the anvil.

He picked up the greatsword that had just been forged.

The pure white light on the greatsword flickered in and out, occasionally revealing a blade that looked like silver.

Then, Hephaestus swung his pure white greatsword and slashed fiercely in Shirou's direction!

A white slash, shaped like a crescent moon, hurtled towards Shirou.

"This is----!?"

Shirou frowned slightly and immediately retreated, avoiding the slash.

After Shirou narrowly dodged, the white slash instantly cleaved a distant mountain peak in two!

Turning his gaze away, Shirou continued to look at the pure white greatsword in Hephaestus's hand, his eyes narrowing slightly.

"A sword created by the gods..."

An incomprehensible, unparsable, and incomprehensible tool.

Without a doubt, this is a sword comparable to an EX Noble Phantasm!

Chapter Twenty-Two: Confronting the Gods!

While Shirou was pondering, Hephaestus unleashed another slash.

"projection!"

This time, Shirou had no intention of dodging any longer. Without hesitation, he projected thousands of A+ rank Noble Phantasms and fired them at Hephaestus without restraint!

Seeing this, Hephaestus fearlessly swung his pure white greatsword once more, unleashing several crescent-shaped white slashes!

boom----! ! !

At the moment when the destruction of thousands of Noble Phantasms collided with those several slashes, a gale suddenly swept in reverse at the center of the battle, sand and dust rose into the sky, and the entire area was engulfed in a violent tornado.

Standing at the center of the relentlessly attacking tornado, Shirou looked intently at Hephaestus, who held an iron hammer and a pure white greatsword.

"It seems that this guy concealed his aura for several days in order to forge this divine weapon. Now that it is completely finished, he no longer needs to hide himself."

Shirou sensed that the situation was not good.

Even though his physical strength now surpasses that of Hephaestus, the 'God of Fire and Craftsmen', he lacks a weapon capable of matching him.

There is no way to fully unleash that endless magic power if you fight with only physical strength.

Although he now possesses the "Third Star Particle Body" and has further strengthened himself after becoming a Godslayer, Shirou is now able to project Noble Phantasms that are comparable to their original forms, and is no longer limited to having the highest quality Noble Phantasms that are "swords". However, he still cannot project Noble Phantasms of the EX level.

"If only I had an EX-rank Noble Phantasm..."

Shirou murmured with longing.

In this magical state, as long as one possesses an EX Noble Phantasm, one can naturally unleash it at will.

But Shirou also knew that this was still a difficult task for him at the moment.

Just then, Hephaestus moved again, slamming down his hammer and causing a huge crack to appear in the earth.

Anyone else might have fallen into the abyss below the crevice, but Shirou didn't care at all and quickly retreated to the edge of the mountain.

However, Shirou did not relax because of this, because he knew that Hephaestus's real attack would come after these huge cracks.

The earth shook and molten lava surged forth from the depths beneath the fissure, like a volcanic eruption, with massive and violent magma shooting into the sky!

Upon seeing this, Shirou immediately leaped high into the air, soaring above the clouds to look down.

His body surged with magic, as if azure flames flickered around him.

Now he can use this endless magic to make his body travel through the sky.

As Shirou dodged the erupting lava, Hephaestus didn't stop moving either, swinging the pure white greatsword in his other right hand once more.

A pure white slash flew swiftly toward Shirou, who was constantly dodging the molten lava surging from the earth's core, but at this moment Shirou no longer needed to dodge.

"projection----"

Magical light surged, and a deep red greatsword was completed in Shirou's hand.

Primordial Fire

Grade: A

Type: Anti-personnel Noble Phantasm

The prototype of this Noble Phantasm is the "Sword of the Meteorite Iron (Aestus Estus)," which belongs to the Roman Emperor Nero. It will be engraved with flames when the emotions are high, and the sword is inscribed with the inscription Regnum Caelorum et Gehenna (Latin: Heaven and Hell).

The "Primordial Flame" held in Shirou's hand ignited with his soaring fighting spirit the next second, and then Shirou infused it with magic power, and the crimson greatsword unleashed a fiery slash.

Bang!

The two slashes collided suddenly, adding power to the tornadoes surrounding the battlefield and making them even more violent.

The next moment, Shirou's figure flew down like a blue shadow, heading straight for Hephaestus, who was wielding a pure white greatsword and an iron hammer.

"What!?" Hephaestus was shocked to see Shirou unharmed and even flying towards him at high speed.

The pure white greatsword in his hand was...

Even the most powerful artifacts couldn't defeat the person before him.

Those who can face the gods without being at a disadvantage—there must be only one kind in this vast world, and that is…

"You are the 'Godslayer'!?"

Hephaestus's pupils contracted sharply as he recognized Shirou's identity.

"Ha, you only recognize me now? Isn't that a bit too late?!"

Shirou snorted coldly and swung his crimson greatsword "Primordial Flame" with all his might, slashing fiercely at Hephaestus's body.

Faced with this incredibly swift attack, Hephaestus immediately raised his pure white greatsword to parry.

Clang!

The clear clang of weapons clashing rang out, causing the earth to tremble once more.

The magicians at the foot of the mountain, upon hearing the soul-stirring sound, couldn't help but look up at the mountain peak in terror.

Although they couldn't see the two figures fighting on the mountaintop, they could see the molten lava rising into the sky and the raging tornado.

The entire mountaintop trembled violently as Shirou fought Hephaestus, and finally could not withstand it any longer. With one earth-shattering clang after another, the summit of the highest mountain in Greece... collapsed.

Rumble!

As the mountaintop collapsed, rolling rocks fell rapidly, creating a thunderous sound.

The magicians gathered at the foot of the mountain watched in awe as the summit of Greece's highest peak collapsed.

Liliana and Erica, who followed closely behind, also stared wide-eyed in disbelief at the mountain peak.

"Is this... the battle between the Demon King and the Gods...?" Erica's pupils trembled slightly.

Liliana, standing to the side, had the same expression. Although she had witnessed the battle between the 'Godslayer' and the 'Disobedient God' in Rome before, seeing it again now still left her deeply shocked.

……

On a mountaintop unseen by the magicians, the Demon King was engrossed in a battle with the gods, oblivious to the destruction he caused and the outside world.

Clang!

After another clash of greatswords, Hephaestus and Shirou were both knocked back, both deeply surprised by each other's power.

Shirou's crimson greatsword "Primordial Flame" shattered under the pure white greatsword in Hephaestus's hand.

"Even an A-rank Noble Phantasm can't last long..." Shirou sighed softly as he looked at the red magic fragment in his hand that was gradually fading away.

At this moment, Hephaestus's eyes were sharp as he stared intently at Shirou ahead.

"I must say, you are indeed the strongest mortal I have ever seen!"

"Your strength is also beyond my expectations," Shirou replied in kind.

This was no exaggeration; at this moment, Shirou deeply felt just how powerful the physique of a god truly was.

Chapter Twenty-Three: Your artifact is truly amazing!

Gods rarely use fists or kicks in combat, but their physical strength is immense. Any god can survive and communicate freely in the vacuum of space. Moreover, their punching speed and physical movement speed have reached sub-light speed. Their powerful bodies alone are enough to allow them to roam freely in the universe.

Even for a second-level god whose soul resides in an ordinary human body, their physical strength is still unimaginably terrifying to the magicians of this world.

Now Shirou understands why Nidhogg, the 'black dragon' in Norse mythology, hid beneath the World Tree and gnawed on its roots instead of directly destroying the gods.

Even a powerful creature like the 'Black Dragon' would likely not survive an attack by a group of powerful deities.

That's why it relied on its powerful devouring ability to gnaw at the World Tree, indirectly causing Ragnarok.

Shirou, having undergone two physical advancements, was only able to subtly suppress Hephaestus, one of the twelve Olympian gods of Greece, but defeating him would be no easy task.

The two who separated again noticed the collapse of the mountaintop, but since they both possessed the power to levitate, they didn't care at all.

“Foolish mortal, even if your physical strength is greater than mine, as long as you cannot kill me completely, you cannot escape the fate of destruction.”

Hephaestus, one of the twelve Olympian gods, with a burly build, cast a contemptuous glance at Shirou as if he were an ant.

Upon hearing Hephaestus's confident words, Shirou smiled.
