Back on the Nautilus, Fujimaru Ritsuka, Mash, and Li Xing were not happy despite having defeated Artemis. All their Servants had been sacrificed.
"Next, we head to the Void's Maw, where Poseidon awaits. Currently, our only Servant is Li Xing. Fortunately, he's a divine Spirit Servant. Li Xing, can you still hold on?" Da Vinci asked, tilting her head towards him.
"No need to worry. We've reunited after so long, and I haven't shown you the true power of a Ruler yet. Leave it to me. Poseidon, with one less God Core, is no match for me," Li Xing assured them with a smile, which eased their minds considerably.
Suddenly, the Nautilus shook violently. A massive vortex appeared on the sea's surface and forcibly pulled the ship towards it. Nemo immediately decided to let the Nautilus be drawn in, as this was the only way to approach Poseidon.
"No need for that. You all go ahead. I'll handle this."
"Li Xing? What do you intend to do?"
Li Xing chuckled, "Don't mind me. I'll catch up."
Seeing this, everyone had a rough idea of his plan. Li Xing didn't say anything further. He turned and left the control room, heading outside the Nautilus.
The sea god Poseidon manipulated the water currents, launching fierce attacks on the Nautilus, but Li Xing severed them one by one with his blade. As he approached Poseidon, Li Xing also manipulated the water currents, pushing the Nautilus towards the Void's Maw while he stood suspended in the air above Poseidon.
"Li Xing!"
"Mr. Li Xing!"
Fujimaru Ritsuka and Mash exclaimed simultaneously from inside the Nautilus. Was Li Xing going to face Poseidon alone?
Li Xing smiled at the Nautilus and waved. Then, his body emitted a white light, his black attire transforming into a long robe, somewhat reminiscent of Qin Shi Huang's imperial robes.
"Arbiter, Ruler, Li Xing, is here to pass judgment. Sea God Poseidon, do you know your crime?"
However, Poseidon had fallen into madness and did not answer Li Xing's words. No, he responded with a monstrous tsunami.
"It seems you admit your guilt and wish to resist to the death? You think I cannot judge you? I have studied," Li Xing said with a smile, summoning three swords: "Chasing the Sun," "Riding the Moon," and "Pursuing the Stars."
"Imperial Sword, Treasure of Divine Punishment for Evil. Evil is what I judge. In the name of the Star Gods, I declare Poseidon, the Sea God, to be an evil against human history. I sentence you to immediate execution."
Li Xing manipulated the three swords, launching them towards Poseidon's mecha below. But Poseidon was no ordinary god; these three swords did not pierce his mecha.
"Still resisting? Do you think I cannot punish you? I have studied!"
The three swords suddenly flew into the sky and then shot towards Poseidon's mecha again. This time, however, the swords were spinning at high speed. If direct penetration failed, he would drill through. If that didn't work, Li Xing planned to use Thor's hammer from Norse mythology.
Fortunately, this time it succeeded. The three swords pierced Poseidon's mecha simultaneously, precisely hitting Poseidon's three God Cores.
With his God Cores destroyed, Poseidon exploded violently. At this moment, the Nautilus had not yet entered Olympus. Li Xing couldn't let the explosion affect Chaldea, so he quickly used the two large wings of Susanoo to envelop Poseidon. However, due to his proximity to the explosion, Li Xing's Spirit Origin was directly injured.
"Ouch, this is bad. Li Yun, protect my body..."
This was the last thing Li Xing said before his consciousness faded. Li Yun quickly flew out and took Li Xing towards the stars. Once in space, he could simply replace his Spirit Origin; a broken one could be swapped for a new one. It was that simple and crude. However, Chaldea would not witness this. The Nautilus had already been sent to Olympus by Li Xing. In short, to break through Atlantis, they had been wiped out.
...
(Greatly condensed.)
Chaldea entered Olympus, only to be immediately attacked by Zeus's lightning. Fujimaru Ritsuka and Mash went out to gather information but ended up fighting the city's soldiers. The soldiers here were incredibly powerful, and Mash was no match for them. Fortunately, a woman in red, wearing a kasa, appeared and rescued Chaldea in the nick of time.
Shinmen Musashi-no-Kami Fujiwara no Genshin, she had another name: Miyamoto Musashi. Yes, this Miyamoto Musashi was a woman. She was a Miyamoto Musashi from an unknown Lostbelt, whereas the Miyamoto Musashi of Pan-Human History was a man.
Due to the nature of her "Heaven's Eye," Miyamoto Musashi drifted through the Lostbelts. Later, she met Fujimaru Ritsuka in Shimousa and formed a bond. After becoming a Heroic Spirit, Miyamoto Musashi continued to drift, helping Chaldea in the first Lostbelt, Russia. Now, she had drifted to this fifth Lostbelt and had been waiting in Olympus for a long time.
With Miyamoto Musashi's help, Chaldea successfully escaped but encountered the city guards, the Bronze Giants. Fortunately, two masked figures led them away. Fujimaru Ritsuka and the others were now hidden underground. Zeus was not omniscient, and he could not search underground. Here, they also learned that the Servants who had arrived in Olympus earlier had been completely annihilated.
...
Unable to find Chaldea, Zeus was enraged and ordered Demeter, the goddess of agriculture, to find and destroy Chaldea.
Unable to find Chaldea, Demeter wreaked havoc throughout the city. Fujimaru Ritsuka couldn't bear to see so many casualties and led everyone out with the Heroic Spirit cannon created by the previous Servants to battle Demeter.
Unexpectedly, Demeter's strength was too great; the Heroic Spirit cannon was useless against her. However, Caenis suddenly appeared and handed over Artemis's legacy to Mash. Mash then transformed into a mecha, and Fujimaru Ritsuka filled it with Command Spells. The black cannon fired a red laser, directly shattering Demeter's God Core.
It turned out Caenis had encountered Chaldea. Caenis was annoyed by Li Xing's previous help and, in her search for him, had infiltrated the Nautilus. However, she was captured by a cake from Director Goredolf. This led her to hand over Artemis's legacy to Da Vinci for processing, giving Mash the power to destroy the Machine Gods.
(No, still too verbose. Delete again.)
After defeating Demeter, they decided to combine seven small summoning circles into one large summoning circle to summon a Grand Servant.
Along the way, Chaldea encountered some obstacles, namely Kiara and Aphrodite. However, Kiara was repelled, and Aphrodite was eliminated by Mash's Black Spear.
Back underground, they met two hidden individuals: the Masters from the first and fourth Lostbelts, and the Divine Bride Europa. There was also a neutral Servant, Muramasa Sengo.
With everyone's help, the Grand Summoning device was completed. However, they encountered the Gemini Dioscuri. After a fierce battle, they finally defeated the Dioscuri.
But Europa was captured by the Alien God's Apostle Ashiya Dōman, and Zeus mind-controlled Europa, intending to pit her against Chaldea. Chaldea defeated Europa and the Bronze Giants, and Holmes knocked Europa unconscious.
Finally, Zeus's true form appeared – a massive mecha floating in the air. Chaldea would face the omniscient, omnipotent, sky-ruling god, Zeus.
Just then, the Grand Summoning Circle summoned Ares, the God of War, and Romulus, the Ancestor of Rome, a Grand Lancer from the Gold Saints of Sagittarius. With the combined help of Romulus and Ares, they defeated Zeus. Mash activated her black cannon and destroyed Zeus.
However, after Zeus's death, a rift appeared in the sky, revealing an eye. Just one glance, and Ares, the God of War, was annihilated.
Chaos, the source of the Twelve Machine Gods. The twelve main gods of Greece had come to Earth using the power of Chaos. Just as everyone was at a loss, Miyamoto Musashi stepped forward and said she had a way to close the void rift.
At that moment, a white light descended, and Li Xing, clad in white armor, appeared before them, holding a blue and white sword.
"It's been a while, Ritsuka, Mash."
Seeing Li Xing in his resplendent attire, Fujimaru Ritsuka exclaimed with joy, "Li Xing! You're alright! We thought..."
Li Xing directly interrupted Fujimaru Ritsuka, "I'm not looking for you. I'm looking for her, Musashi-san."
Miyamoto Musashi paused for a moment, then chuckled, "Young man, you seek me? While it does make me happy for a handsome youth to approach me, I have more important matters to attend to right now. It seems you are also a swordsman. If there's an opportunity, perhaps we can spar."
Although this was Li Xing's first time meeting Musashi-san, the thought that had been in his heart never wavered. Li Xing sheathed his sword and knelt in mid-air, "Musashi-san, my name is Li Xing. Like you, I am a traveler from a foreign Lostbelt. In my homeland, there are stories of you. I admire you greatly. If given the chance, I would love to witness your 'Book of Five Rings'."
This sudden confession stunned everyone. It was a crisis, and shouldn't he be more serious?
Li Xing's admiration for Musashi-san was not without reason. After his parents' death, Li Xing discovered anime. Since the Type-Moon series was his entry point, he watched many of their works. He continued until he saw that radiant Flower of the Celestial Origin, living happily even without a home. Li Xing had a home, but no family, and spent his days idly with his inheritance.
(The author's entry point was Akame ga Kill, and further back, Naruto.)
The moment Musashi-san disappeared in the story, Li Xing felt a desire to travel to the world of anime and mend those regrets. Musashi-san was Li Xing's initial goal. However, in the first world, Li Xing found a new family, and naturally, his aspirations grew. Traveling the stars with his family. Now, his first goal was about to be achieved.
Digressing, back to the present.
Musashi-san didn't understand why the young man in front of her liked her so much, but she couldn't give Li Xing a perfect answer right now.
"I'm sorry, thank you for liking me so much, but I'm about to leave. Please help Fujimaru Ritsuka and the others in my stead!"
Saying this, Musashi-san drew her two swords. Li Xing frowned and quickly drew his sword, carving a starry sky in the air, separating everyone from himself.
Rejected in his romantic advances, Li Xing turned to Fujimaru Ritsuka, "Do you remember what I said? I had other objectives. Yes, it's this moment. It's a shame that reforging my Spirit Origin took some time, leaving no chance to chat more with Musashi-san."
Then, Li Xing looked at Musashi-san, "Musashi-san, I'll sing you a song. It's a song written specifically for you in my homeland, titled 'Ittō Ryōran'."
Before anyone could answer, Li Xing began to sing, his movements not ceasing as his Star God power surged forth.
...
"Ittō Ryōran~"
"To live on, the way of the Asura's dance~"
(This is a song I really like. If you have money, you can listen to it. It's an FGO first-anniversary song.)
"Chaos, hmph, just a mere Machine God, not a problem! Let me show you what a Star God is!"
As the song ended, Li Xing shouted, his body already exceeding the limits the world could bear, cosmic power converging onto his Nebula Blade.
"Tengen Issen!"
With Li Xing's single strike, the ultimate destructive power concentrated on Chaos's eye. Chaos was instantly annihilated, and the void rift was closed.
Li Xing's body began to fade. He could feel the rejection of the two great Counter Guardians. He then turned back and smiled at Musashi-san, "I hope you can bloom forever, radiant Flower of the Celestial Origin..."
Finally, a Star God's blessing fell upon Musashi-san, and Li Xing completely vanished.
Musashi-san watched all this, a strange thought stirring in her heart. Just as she was about to say something to Fujimaru Ritsuka, she vanished from the starry sky in the next moment, just like Li Xing. Musashi-san was a "selected person." The moment Li Xing fulfilled her mission for her, Musashi-san should have disappeared. However, Li Xing had changed her fate. Similar to Siduri's situation, her continued presence would create a singularity or even a Lostbelt. She too was rejected by the Counter Force. This was the end of Zero.
