Irisviel arrived at Lixing's home the next day, while Maiya Hisau was responsible for another Irisviel puppet in the Emiya family's warehouse.
Meanwhile, in the Church, Tokiomi Tohsaka wanted to cooperate with Rider. Due to Lixing's existence, this Holy Grail War might be lost. However, Waver's group had no chance. Waver wanted to prove himself, so he naturally wouldn't cooperate. With a constant victor, Waver felt he could never prove his talent.
Tokiomi Tohsaka couldn't find a cooperation partner, so he had to choose Artoria's side. However, Kirei Kotomine had previously offended the Einzberns in the forest. Irisviel proposed that for cooperation, Kirei Kotomine must leave Fuyuki, as she felt he was very dangerous.
Tokiomi Tohsaka had no choice but to ask Kirei Kotomine to leave Fuyuki first and return after the Holy Grail War.
However, Kirei Kotomine had already been incited by Gilgamesh's inner evil and didn't want to leave Fuyuki. Therefore, he had no choice but to kill his master, Tokiomi Tohsaka.
That night, Tokiomi Tohsaka gave Kirei Kotomine a dagger and wrote his will in advance. Since Tokiomi Tohsaka didn't know when he would die, he said his goodbyes. As Tokiomi Tohsaka was about to leave, with his back to Kirei Kotomine, he was stabbed in the heart by Kirei Kotomine's dagger.
Gilgamesh immediately appeared. Since his Master was gone, he naturally had to contract with a new Master. Kirei Kotomine was the best choice.
It was a complete service: the murder weapon, the will, a swift contract signed in front of Tokiomi Tohsaka's corpse.
...
Night.
Lixing had Qin Shi Huang contact Iskandar, and they agreed to a decisive battle on the Fuyuki Bridge. Qin Shi Huang naturally agreed with Lixing's memorial and had no objections.
On the Fuyuki Bridge, Lixing, Qin Shi Huang, Artoria, and Irisviel stood together. On the other side, Iskandar arrived with his Master, Waver, for the appointment.
Gilgamesh sensed the magical energy reactions from this side and wanted to come over. However, the people on the bridge suddenly had no magical energy reactions.
"Damn Lixing! He actually snatched this King's prey twice!"
...
In a desert, Iskandar rode his horse, bringing Waver along. Waver was already Iskandar's subject and was willing to fight alongside his King.
"Hahahahaha, Lixing, I never expected you to be my opponent. Today, I'll let you witness the Conqueror King's army once again!"
Iskandar shouted and led his army in a charge.
Artoria wanted to use her Holy Sword, but Lixing stopped her with his hand: "Let me do it. I'll show you what a Star God is."
Lixing walked forward alone, his Star God power surging, and space seemed to collapse.
"This sword is called Star Nebula. I created it based on the weapon of the Venus goddess. With the power of the Star God, it is a true Anti-World Noble Phantasm. Conqueror King!"
"Ultimate Art: Absolute Zero, Freezing Ten Thousand Miles."
Lixing slashed horizontally, and visible ice rapidly condensed, freezing the entire desert of the Reality Marble. Iskandar's army was instantly frozen. However, Iskandar was still charging, now flying through the air on his divine chariot.
"Heavenly Origin Slash!"
Lixing slashed at Iskandar in the sky. A beam of blue light pierced the heavens, instantly destroying the divine chariot and vaporizing the two oxen. The Reality Marble was broken, and Iskandar and Waver fell onto the Fuyuki Bridge.
Iskandar placed Waver behind him, telling him to live on and inherit the King's dream, which was the responsibility of his subject.
"Lixing! A god I have never heard of! I, Iskandar, the Conqueror King, challenge you again!"
"Glory lies in the distance. It is precisely because it cannot be achieved that one must challenge it. Sing of hegemony, display hegemony, all for the sake of the subjects who gaze upon my back!"
Iskandar shouted loudly, brandishing his sword and charging at Lixing. Lixing smiled faintly: "Very well, a true man! Farewell, Conqueror King."
Iskandar stopped advancing. Lixing's sword had already pierced Iskandar's chest. As an Archer summoned by the Holy Grail, Iskandar made his exit here.
"Live on, Waver." After saying that, Lixing turned and left the Fuyuki Bridge with Artoria and the others.
...
In the Fuyuki Civic Hall, the Lesser Grail manifested and spewed out countless black mud.
This was because Lixing had snatched away Gilgamesh's opponent. Kirei Kotomine directly decided to seize the container of the Holy Grail and chose to descend there.
Maiya Hisau was killed by Kirei Kotomine. When Kiritsugu Emiya learned of this, he immediately notified Irisviel. Lixing immediately understood what was happening and decided to go to the Fuyuki Civic Hall, asking Kiritsugu Emiya to go there as well.
...
"Hmph! Lixing, you're finally here? This King has been waiting for you for a long time. Let's settle our previous battle here!"
Gilgamesh stood on the stage, speaking arrogantly.
"That... is the Holy Grail?" Artoria saw the Holy Grail suspended in the air behind Gilgamesh, constantly spewing black substance. It didn't look like anything that could grant wishes.
"Infinite Domain."
Lixing brought Gilgamesh into another layer of the Infinite Domain, preparing to eliminate him there.
"This barrier again? How boring!"
Gilgamesh chuckled, drew Ea, and began to charge: "Epic of the Genesis! At the time of creation, the void offered congratulations. With my Ea, I tear the world asunder. Surrounded by the star-filled臼, the heavenly hell is the end of the eve of creation!"
Lixing was not polite either. He flew into the sky, a long spear appearing in his hand: "Extinction is this thrust! Burn everything!"
"Enuma Elish! The Star of Genesis!"
"Sun Disc! Obey Death!"
The wind pressure caused by Ea's rotation had already cleaved this Infinite Domain. Lixing's flames collided with Ea's destructive power, causing a violent explosion in the Infinite Domain, powerful enough to destroy a planet.
Lixing, of course, did not let the Infinite Domain collapse. He wrapped it with layer after layer of Infinite Domain, preventing the explosion from affecting anything else.
The Anti-Divine Noble Phantasm used by Lixing did not inflict much damage on Gilgamesh because Gilgamesh detested gods, and his divinity dropped to B upon arrival. However, Lixing had the support of Star God power, and Gilgamesh's magic could not last long. His armor began to crumble.
...
"I lost. This King admits you are a true god..." Gilgamesh, naked, stood in the Infinite Domain, sheathing Ea. Numerous burns appeared on his body, and his Spirit Origin was gradually collapsing.
"If you had held on a little longer, I might have been the one to lose. My Spirit Origin also has limits." Lixing stood on the ground, ragged, panting heavily.
"Hmph! This King is the sole ruler above and below the heavens, not one to make excuses! Well... Also, Siduri is in your care..."
With that, Gilgamesh completely dissipated. Although this was not Gilgamesh's full power, it was still at the peak of a normal Holy Grail War. He was indeed the King of Heroes.
