MIKU, inexplicably turned into a Pokémon again, flew at high speed for a kilometer in the air before plummeting into the Homunculus ranks like a cannonball—
Boom!!!
Immediately, snowflakes mixed with splashing mercury droplets, along with flying remnants and severed limbs, bloomed into a spectacular red peony in the vast, white, frozen snowfield.
As mercury droplets fell onto the white snow, one by one, twin-tails girls with green hair appeared in the world. Mercury-made shapeshifting weapons and the Homunculi engaged in battle, instantly turning the vast snowfield red with flying flesh and blood.
MIKU, capable of contending with the Army of the King of heroic spirits, was, of course, no match for a mere group of mass-produced Homunculi. Along the way, Rin and the others walked straight through various magical traps and mechanisms, trampling countless of them. With an average anti-magic power of EX for everyone, any magic trap less than the Five Great Magics level was truly not worth their attention.
"Master, this 'welcome fireworks' from the Einzbern Family is truly impressive. It's time for us to return the favor, isn't it?"
"Ah, but no large-scale destructive attacks are allowed, because everything we damage will be our own property. This castle is really nice; I plan to move it to Fuyuki with magic. The current Tohsaka Residence looks too small compared to this."
"Understood!"
Jalter suddenly increased her speed, taking the lead and charging towards the castle gate, which was covered by layers of barriers! With a wave of her evil dragon battle flag—
Boom!!!
The entire castle shook from Jalter's single blow. The powerfully protected magical barriers, layered one after another, shattered like an eggshell. The castle gate instantly disintegrated, and Rin and the other three broke through.
Stepping onto the ornate, painted floor of the castle, Rin and her companions were met by all the members of the Einzbern Clan at their highest state of alert. Leading them was a solemn old man with snow-white hair that almost touched the ground, who was likely Zwert Einzbern, the eighth patriarch of the Einzbern.
Jubstacheit von Einzbern. Since inheriting the position of the eighth patriarch, he has been commonly known as "Zwert Einzbern." By continuously extending his life, he has lived for nearly two centuries, leading the Einzbern Clan after they shifted from pursuing the Holy Grail to the Holy Grail War. He is an Einzbern humanoid terminal created during the era when the winter saintess Justitia initiated the Holy Grail War; one could say he was created as the leader of the Homunculi to win the Holy Grail War for the Einzbern.
"Who are you?! Our clan has never involved itself in any disputes of the magical world. Why do you invade?!"
Facing Zwert Einzbern's righteous questioning, Rin felt an urge to vomit. She took two steps forward, tilted her twin-tails head, and said casually:
"Oh~ If that's how you put it, then the Holy Grail War, which occurs every sixty years, has nothing to do with you either? Stop pretending to be ignorant, old man. Do you really not recognize me?"
Rin's approach was to lay everything bare, with no intention of playing games with Zwert Einzbern. The old patriarch, whose hair was all white and who was on the verge of death, took a deep breath to calm his heart, which had been unperturbed for over a hundred years, and said:
"Tohsaka Rin, what exactly is the Tohsaka Family's intention?"
"Isn't it obvious?!"
Activating her Heroic Spirit Core, the Lake of Ruin was directly plunged into the ground in front of Zwert Einzbern!
"The Matou Family has already gone ahead. Now it's your Einzbern's turn. We, the Tohsaka Family, have already obtained the Holy Grail! Therefore, the so-called Three Founding Families of the Holy Grail War no longer need to exist. For beings who know too much, what do you think should be done?"
At this moment, the unique soul aura emanating from Rin and the three people beside her already made Zwert Einzbern realize what this was.
"Heroic Spirits? The Holy Grail War has ended, how can Heroic Spirits still remain in the world... Wait, why have you become a Heroic Spirit? Could it be that you really obtained the Holy Grail!!?"
A golden divine light flashed in Rin's hand, and a golden chalice, as if real, floated in her open right palm. Unique energy fluctuations emanated and spread from the mouth of the cup, which was filled with colorless liquid, washing over the souls of everyone present.
"The chalice... it's complete!"
All the Homunculi of the Einzbern present stared at the golden chalice in Rin's hand as if their souls had been lost. That was the object their Einzbern had pursued, explored, and prayed for ever since its birth a thousand years ago. The miracle they had longed to achieve for a thousand years was finally realized, but in the hands of an enemy... "Then, the purpose for which the Einzbern was born has now also been achieved, so..."
"Rest in peace!"
The final words came from Jalter, the most bloodthirsty among them. In her opinion, saying anything more to these Homunculi was superfluous. Her waving battle flag slashed through a body like a sword, instantly exploding it like a flesh bomb!
Flying flesh and blood instantly stained the entire castle foyer, but—
"That old geezer and a few elder-level Einzbern figures are all magic projections. We need to find them quickly; no one knows if they've prepared escape routes like dog holes. All Homunculi seen, whether low-quality mass-produced ones or core figures with mimetic personalities, are to be left alive, without exception. Regardless, they are all beings programmed like machines, so there's no possibility of surrender."
Rin pulled out Avalon and gave orders, then separated from the Sabers to clear out the entire Einzbern Castle.
At this moment, Artoria said to Rin:
"Master, allow me to pick up Illya.
When Kiritsugu Emiya first summoned me to this world, I resided in this castle for a period of time, and I know where Illya's room is."
"Alright, I'll leave it to you."
"Mm."
The disaster of Einzbern Castle thus descended without reason or warning.
Four Heroic Spirits, like spirits prowling in the night, reaped lives as they roamed throughout the castle.
Aside from one who went straight to their target in search of something, without much killing, the other three engaged in a bloody massacre.
At this point, the Einzbern Clan's combat weakness was exposed without doubt.
Even Acht Einzbern, who always prided himself on having everything under control, was now in utter disarray.
Faced with such a situation, he was completely helpless.
If other families encountered such a situation, they could still contact their branch families for support through the main family's connections, or request help from allied forces.
However, the Einzbern Family could only rely on themselves.
For a thousand years, as a false Magus family composed of Homunculi, the Einzbern Family was unable to establish branch families, spread their influence, or interact with outside Maguss to build proper diplomatic relations.
Although this gave them strong cohesion, dedicating all their energy to Homunculus and Alchemy research, their technology had almost entered the realm of gods and demons.
However, this also meant that when they fell into such a predicament, they could not call upon heaven or earth for help; they could only rely on themselves!
Rin, holding Avalon, walked through a path of blood and severed limbs.
Countless inferior Homunculi emerged from all corners of the castle, many of them incomplete or even defective Homunculi, all activated.
Incomplete limbs, naked bodies, Rin killed, or rather, dismembered them to the point of being so annoyed she wanted to vomit.
Their dazed, inorganic eyes, yet they possessed the same appearance and body structure as Irisviel, only lacking the internal essence.
While Rin felt no guilt for this, seeing Irisviel's face so defiled made Rin uncontrollably nauseous.
Indeed, this face only needed to belong to Irisviel!
These inferior pieces of trash should all be completely swept away at once!
With a slash of her magic-infused blade, a roaring sword qi whirlwind tore apart all the Homunculi blocking her path.
Rin rushed towards the Einzbern Chapel, her detection magic telling her that Acht Einzbern was in that direction...
