My youth story, a crossover anime, turns out, is FGO!

In outer space, under the combined attack of Karna, Gilgamesh, and King Arthur, Tiamat's enormous and terrifying body slowly disintegrated amidst the incomparably brilliant and devastating stream of light.

“Arrrrrrr…”

What is she thinking? Perhaps, as a physical being, she doesn't have much capacity for thought.

But the enormous star-shaped eye remained fixed on the distant blue planet, which was clearly just a dim blue dot, yet Tiamat did not look away.

That similar yet different planet was the home she was unable to visit.

Then, golden spirit particles began to float in outer space.

The two gods present, along with several heroic spirits including Makoto Aoki, all turned their gazes toward Qin Shi Huang. At that moment, golden particles floated around his body, just as the heroic spirits had done when they left the stage.

"So it turns out I was the one who left first?"

Qin Shi Huang seemed to be deep in thought.

"You've completely unleashed the power within your spirit core, realized your potential, and still managed to persevere until now. Even I have to look at you with new respect. You're truly an outstanding warrior... Well, no, not a warrior. Even if you're not the sun, you're just like that golden one—a drinking buddy with whom I can have a good chat."

Ramses II smiled with delight and showered the emperor with praise.

Qin Shi Huang used the "First Emperor" treasure to forcibly elevate his spiritual foundation, standing alone in front of Tiamat. The pressure he faced was unimaginable.

Although the most important part of the siege of Tiamat was that Smoke Mirror used the underworld and Noble Phantasms to erase Tiamat's immortality, Qin Shi Huang's contribution in launching the general offensive, the Great Wall spanning the stars, the Epang Palace traveling through space, and the restriction of Tiamat's production and movement speed by laws are also undeniable.

Not to mention, he was also very active on the battlefields of Earth. The Great Wall was active all over the world. As the most important line of defense against Lahem, the Fallen God Bow broke through Tiamat's winged horns. He was actually the one who bore these losses.

“This is truly the pinnacle of humanity,” Gilgamesh offered a rare compliment. “This is the time you should have appeared, but 2000 years have passed since your time.”

"Thank you very much for your assistance, First Emperor of a foreign land," Karna said earnestly.

Romulus remarked with a touch of melancholy, “It is said that Rome was later called Da Qin, which is quite an interesting coincidence.”

The Divine Ancestor did not refer to the Qin Dynasty as Rome; he could see that Qin Shi Huang was taking a completely different path.

However, everything in the world eventually leads to Rome, and perhaps in the end, all paths lead to the same destination.

"Thank you for your help, Your Majesty," Aoki Seiya said goodbye. "Please rest assured and leave the rest to the people now."

Qin Shi Huang nodded slightly, neither agreeing nor disagreeing.

As for the two gods, Smoke Mirror merely chuckled, while Astraea pondered how to judge the sins of an emperor, and how to define sin if one bears the burden of everything for the sake of all people.

Are you leaving?

The traveler flew lightly to the First Emperor's side and tugged at his sleeve.

Qin Shi Huang looked at the traveler, his gaze softening slightly, and unusually, he explained, "I was just thinking."

"I seem to have glimpsed some other possibilities just now," Qin Shi Huang scoffed, thinking of his past self who chose mechanical ascension. "That talk of ascending to immortality is nothing but a joke."

"The future and destiny must be in my hands."

In the pan-human history, Qin Shi Huang did not choose the path of transforming himself into a mechanical being. Instead, he died in the original timeline, and a few years after his death, the vast Qin state disintegrated.

However, Qin Shi Huang's way of thinking was different at different times. Even if he saw himself in the Lostbelt, opening up a true kingdom where humans and humans were united and carrying the planet on his own, he would not agree with it.

People with different paths cannot work together; they embarked on different paths a thousand years ago.

"I came here only to rid the people of this great scourge. Now that my purpose has been achieved, there is naturally no reason for me to stay."

"As an emperor, one must ultimately be with all people. To only understand this at the very end, what a laughable man..."

In the end, as someone on the other side sneered, the First Emperor closed his eyes, his spirit disintegrated, and he returned to the Throne of Heroes.

"Everyone."

Makoto Aoki did not dwell on the disappointment of Qin Shi Huang's departure, but immediately and solemnly said to the surrounding Heroic Spirits, "Although we have defeated Tiamat, our mission is not yet over."

"If Taigong Wang's good plan fails to work, then the Lahem bred by Tiamat will become a great threat. In this short time, please do your part for us once again."

All the heroic spirits had anticipated this and rushed back to Earth with all their might, including Smoke Mirror, who also followed along with great interest.

He could smell the smoke of battle; Tiamat's defeat did not signify the end of the war.

However, once the beasts are destroyed, the heroic spirits can only remain for a very short time, so they must seize the last second.

“Goddess Astraea.” Makoto Aoki looked at Astraea. “You should know why I summoned you.”

"nature."

The goddess of gold raised her chin with a reserved air, yet her divine golden eyes stared at Makoto Aoki like those of a hawk.

"My Master, Makoto Aoki, tell me, are you guilty? Do you need my judgment?"

"Of course."

Makoto Aoki nodded without hesitation, his mind filled with many past events: "I am not a hero, not a saint, and not an emperor. As a mortal, or as a member of the human race, whoever I am, I am guilty. Just like the beast, she is the original sin of humanity."

“That’s right. Even if Tiamat’s return is a sin, the humans who abandoned their mother are also burdened with sin.”

"However, as a collective of humankind, swallowing the bitter pill and continuing on to bid farewell to the gods... such actions cannot be judged as sins."

Astraea looked at Makoto Aoki as if she could see into his heart: "However, Master, as an individual, you can judge your own crimes."

"Do you need my judgment to find relief? Whatever the answer, I will fulfill the mission that summoned me, in accordance with the contract."

"...No, I don't need it."

After a long silence, Makoto Aoki finally spoke, his voice firm: "I still have things I must do. As human beings, we all have moments when we have to swallow bitter pills and struggle to move forward."

"Moreover, even original sin does not mean that humanity does not know how to reflect or make amends."

"Goddess Astraea, perhaps there is another possibility, different from the ending of mutual slaughter. Are you willing to wait?"

Astraea, who had abandoned humanity in the Iron Age, said with a complex expression, "Of course, I will witness this ending and judge it."

Perhaps you will create another future.
