Simulate the universe, starting with speedrunning Greek.

When the Germanic leaders on the battlefield saw Achilles' cold, handsome face, covered in blood, as he charged forward, they all cried out in sorrow.

If they don't know the answer, they won't be able to rest in peace even if they die.

"Oh? So you assume a power that's beyond your comprehension doesn't exist just because you can't understand it? Normally, I wouldn't even mention my name to weaklings like you, and you wouldn't be qualified to know. But to think you don't even know me, the renowned Achilles, with my unparalleled body of steel... that's truly infuriating!"

"Ah... Achilles?!" The leaders were stunned. This answer brought a new sparkle to the eyes of these Germanic people who had been despairing at the prospect of death, and their hearts were filled with shock.

Chapter Sixteen: Impossible! A savior who is both a god and a man—isn't that just a Greek invention?

An invulnerable body, faster than the wind and lightning, as swift as a star streaking across the sky!

Ah—! It matches up! It matches the description in the mythology.

Especially since they all sensed the unfavorable situation and began to retreat, even though they were at the forefront of the legion, they were still overtaken from the rear—such speed!

"You said you are... the legendary Achilles! That... the Greek hero of speed, the savior?! Was that the comet run just now?!"

No matter how unwilling they are to believe it, when the facts are presented to them, they have no choice but to believe it.

Even the Germans had such thoughts at that moment.

If the person who killed them wasn't some nobody, but a legendary hero, then such a death would at least be tragic and glorious enough.

Just as the Germanic leaders dreamed of becoming Romans after the Romans terrified them.

The mentality of admiring the strong is deeply rooted in their blood and soul, and it even influenced the small island nation of Inazuma in a parallel world in the future.

Ah! It was Achilles who killed me!

The leaders were overjoyed!

Ordinary people killing them... no way! Achilles killing them—yes!

"Stop joking!!" Achilles suddenly roared in fury.

The word "savior" was too provocative for him; it was the word he hated hearing most during his lifetime.

A long spear pierced through the air like a spiral, so fast that it was invisible to the naked eye, as if the wind were gently blowing past one's ear. The next moment, the leader who had spoken was blown apart, and large amounts of tomato sauce were spilled all over the ground.

What happened?!

Completely baffled by what happened, the hero, who was able to communicate just moments before, suddenly went berserk and took the life of one of them.

Even if Achilles were to kill—that's fine! But no one would be unafraid of the threat of death.

The leaders swallowed hard, looking at Achilles in fear, unable to understand which sentence had gone wrong.

Whether it's the comet's run or the savior, these are names known to all, sung by bards, and are praises of his glory and bravery!

Why the praise actually enraged Achilles is something that people can't understand.

Until—they heard it—Achilles suddenly spoke in a low voice: "Don't say that a sinner like me is unworthy to be called a savior. Remember this: barbarians…throughout history, there has only ever been one true savior, and only ever has been. That is the true hero and dearest friend for whom I now serve! And—"

Achilles then unleashed a frenzied massacre, accompanied by the splattering sounds of countless spear afterimages piercing through the enemy.

Standing amidst the corpses—only when these people were dying did he stop his blurry figure, which was barely visible to the naked eye—and slowly said, “It’s just that the movement speed was a little faster. This is not some kind of comet running technique… Even what you call the comet running technique seems a bit exaggerated to me now. At most, it’s just running at full speed, not worthy of such praise.”

Achilles knew what the Germanic people meant by running.

That was the legendary speed at which he comprehended in a desperate situation during his battle with the demon king Talos, enough to set foot in the sky, conquer territories never before set foot by mankind, and cross the realm of gods—a speeding pace that allowed him to run through the sky and be in the same sky as the gods.

At that time, I was truly excited and proud of myself for having mastered this unique skill and surpassed his limits.

But after learning the whole truth and killing his friend with his own hands, the joy of breaking through the limits no longer seems so important. He was surprised by such trivial things, but failed to realize what was truly important earlier. He was the most foolish idiot in the world!

From then on, he could not bear to hear others praise him, because every time he heard praise, it reminded him of how Griffith had been forgotten by the world.

The more he was praised, the more he felt tormented, ashamed, and burdened by the undeserved honor he had stolen.

His feelings of regret prevented him from maintaining his composure, and he often flew into a rage.

If the Germanic people knew that they were killed for this reason, I wonder how they would feel.

However, they still discovered something from Achilles' last words.

The true savior who makes heroes call themselves sinners, repent, and pledge allegiance is their friend.

Those that meet this condition...

If you recall the legends of the hero Achilles even slightly, there's something else that became synonymous with his epic life, rather than his weakness in the heel, which is no longer well-known in this time and space.

No, it won't.

Not only Achilles, but even that one... descended—

The Germans died with immense fear and disbelief.

After all, he is different from heroes like Achilles, who are only demigods but at least mostly stand on the side of humanity.

This could also be explained by saying that Achilles was a very powerful human, but because of his overwhelming power, he was mistaken for a demigod or the son of a god... In reality, there are no gods in this world, and it is impossible for such an ethereal thing as a god to exist.

But what if even that person shows up...?

He was both a hero and a god, transforming into a god of destruction, sweeping across the entire Greek continent, slaying Dionysus, bestowing the title of emperor upon the Mycenaean kingdom, and destroying the world... Yet, he also single-handedly devised the Zero Requiem, which is still talked about by later generations, and in the end, he created the world, plunging the Greek world into a period of unification and long peace.

That demon god, hero god, war god, and martial god is a man who is genuinely described as a god and has been subject to much practical research.

The terrain was drastically altered after the final battle of Greece, all of which, according to historical records, were caused by the aftereffects of the battle.

The world has always considered him a character fabricated by the Greeks to be a boastful fabrication.

The so-called topographical changes must have been caused by natural disasters.

In fact, Achilles emerged

They only accepted its identity after witnessing its invulnerability to swords and spears, which was exactly as described in myths.

What else could be beyond the explanation of common sense, besides myths coming true?

But the existence of even that true savior completely changed the world in their eyes. It was an existence capable of utterly overturning their worldview.

A power slightly exceeding that of humans can be seen as a genetic mutation, and this kind of supernatural ability is barely acceptable.

But—if even demons exist, then they are gods!! Genuine gods!

Chapter Seventeen: The Concept of Unkillable Heroic Spirits – To Kill Them, First Kill Yourself Who Knows Everything About Them.

Gods, those are deities! The aftershocks of battle could bombard mountain ranges, creating abysses and canyons—the work of gods!

A god—is actually coming to destroy Germania?

The mere thought of this horrific fact was enough to fill the Germanic people who knew about it with endless fear and panic!

Previously, the Germanic people had doubts about the existence of Achilles and others. Not only Achilles, but other heroes also made no attempt to conceal their identities or names on the battlefield.

But when their superb martial skills, shining brightly in the last golden age of Greek heroes, once again shone on the battlefield.

Gradually, more and more Germans who had fled the battlefield began to spread such legends in this northern land.

The ancient god Talos has reappeared, leading an army of heroic spirits—formed by the heroes of Greece—invading this land. Heroic spirits—!

Yes, that's what people call those Greek heroes who were resurrected from the past.

Heroes who have been buried for at least several hundred years, human heroes only heard of in myths and legends, have all regained their youth and strength, and are hunting them down on this land at will.

"How...how is this possible? The dead cannot be brought back to life...this rule has been broken."

"This is already a miracle." Some Germanic people, with nowhere to escape, lamented this with extreme pessimism as they faced the powerful heroes before them.

"Resurrection? In our current state, it's hardly a true resurrection. Although we can physically touch and fight, we are not truly living beings. Even if we are killed, we won't really die..." Hector, unusually, had the leisure to describe their situation to the Germanic people before him.

The main reason is that the information he received after arriving in this world still deeply shocks him.

As long as the power of night has not been exhausted and his magic is still abundant enough, he can continue to pull them out of the river of history. Heroes who have already died once no longer have the concept of death.

The bodies they now use to act are not their original selves, but rather something like extracted concepts. Although they possess the same memories, emotions, and souls as in their previous lives, they are more like clones, truly becoming similar to the Servants in the Type-Moon world.

This part of the memory will naturally return to the original body later. It's not that the night can't pull the original body over, but rather that to completely keep the souls in this world, it's necessary to find suitable vessels for the heroes.

These words sounded even more desperate and terrifying to the Germans.

It doesn't even have the concept of death—what kind of monster is this?!

If they are already this powerful without ever being truly resurrected, just how terrifying would these monsters be if their true forms were here?

Thrilling, terrifying—!

"Impossible—if myths were true, then even gods would fall, but how could you, the fallen heroes, have completely lost the concept of death? Absolutely impossible! Liar!"

"Of course, we are not truly immortal. But we are the epitome of the past, summoned from the concept of the long river of mythology, responding to its call. If you want to kill us completely, you must not only kill our souls, but also our achievements and glory, erase our legends—all our deeds, only then is there a possibility of killing us."

Hector recalled that before setting out for battle, Night had given them a hint that they could reveal a lot (of things in public), which seemed to help Night's plans.

Hector was not going to think about the deeper meaning behind it, and at this moment he selectively revealed some of the 'truths' that he had learned from the night that shocked him.

Like a thunderclap from a clear sky, the Germanic people exclaimed, "What!?"

"This is impossible!"

Hector: "Nothing is impossible. If you really want to kill us, you should kill all the humans who know my name and my legendary deeds. That includes yourself, of course. As long as there is one person in this world who knows our heroic deeds, this embodiment of conceptual power will not truly perish."

Knowing how difficult and absolutely impossible this was, Hector, without any hesitation, offered this answer with 'pity' and 'kindness'—an answer that seemed to make the Germans even more desperate.

The Germanic people were devastated.

They couldn't believe it; how could such an outrageous concept exist?

Germans: "Even gods don't have such an infinite number of chances to start over. What right do you, mere human heroes and their dead souls, have to keep coming back to life like this?"

Hector: "Haven't we already told you the answer?"

After speaking, Hector defeated all his enemies with a smile. He mercilessly killed those who were still preparing to resist, and spared those who had completely lost their will to fight and surrendered in despair, taking them prisoner instead.

Those people, after carefully recalling Hector's words,

Suddenly something occurred to me...

They came in response to someone's call.

What's truly amazing isn't these spirits of the past, but rather the person who can summon these beings from the concepts of mythology and history. He is the one who gives these spirits their powerful immortality.

Although, as Hector had previously stated, killing them would be very difficult, practically impossible.

But under normal circumstances, these souls would not be able to be summoned to the present era, and naturally they would not pose a threat to this land.

The truly powerful ones are actually the summoners!

In reality, once the summoner is dealt with, these terrifying heroes who can be constantly summoned become 'not a threat'.
