At this time, the battle in Einzbern Castle still continued.

Corridors, walls, ceilings—every clash between the Servants added a scar to the surrounding environment.

Various valuable antique paintings and furnishings were reduced to wreckage in the war between the two Servants.

Saber, with a wounded left hand, was not Lancer's match, but she still gritted her teeth and persevered.

To avoid falling into a disadvantage in the fierce confrontation with Lancer, she could only wield her sword with her right hand, constantly using “Mana Burst” to strengthen her wrist and compensate for the lack of strength.

Mana consumption was a big problem; this method of increasing wrist strength with “Mana Burst” was not suitable for prolonged combat.

Saber, accustomed to wielding her sword with both hands, even with a way to bridge the gap between them, could only defensively face Lancer’s fierce, wave-like attacks, finding no opportunity to counterattack and gradually falling into a disadvantage.

Kenneth looked at the disadvantaged Saber, not surprised in the slightest, and provocatively said to Kiritsugu Emiya, who was not far behind Saber, “Lancer, go easy, don't completely demolish the house.

Once we occupy this castle, we'll need to spend mana to repair it; otherwise, how could a ruin be worthy of Sola’s status?”

In response to Kenneth’s provocation, Kiritsugu Emiya immediately fired his submachine gun.

This time, Lancer did not quickly return to protect his Master.

The Volumen Hydrargyrum at Kenneth's feet reacted immediately, forming a mercury-like protective film in front of him, blocking all the bullets Kiritsugu Emiya fired.

Within a few seconds, Kiritsugu Emiya had emptied his magazine.

To save time, he didn't waste time reloading, but instead dropped the smoking submachine gun and drew another from his holster, preparing to continue firing, when he heard Kenneth’s declaration of death.

“Slash!”

As Kenneth’s words fell, two mercury tentacles separated from the mercury-like Volumen Hydrargyrum, rapidly compressing into razor-sharp mercury blades only a few micrometers thick.

They then transformed into a dense net, like a net catching a small bird, and swiftly flew towards Kiritsugu Emiya.

Volumen Hydrargyrum, in its normal state, is an extremely heavy liquid substance.

When it moves at high speed, it possesses powerful kinetic energy, and its sharpness surpasses that of laser weapons.

Even the seemingly light mercury net flew at a speed not much slower than a bullet.

Whether it was titanium alloy or diamond, nothing was unseverable in front of Volumen Hydrargyrum.

Just as the mercury blade net was about to hit its target, Kiritsugu Emiya dodged the attack range of the mercury blade net at an almost unimaginable speed and quickly retreated towards the staircase.

“Hmm? Does he also possess some Magecraft?”

Watching Kiritsugu Emiya rapidly disappear from his sight, Kenneth smiled slightly, not overly surprised by what was happening.

After all, battles between Magi often defied logic, so it wasn't strange for his opponent to possess extraordinary abilities.

“Has the mongrel brought by the Einzbern Family fled just like that? If so, I’ll take Saber’s head first, and then capture Saber’s Master…”

Kenneth still believed that Saber’s Master was Irisviel, and Kiritsugu Emiya was merely a mercenary hired by the Einzbern Family.

Just as Kenneth was about to order Volumen Hydrargyrum to cooperate with Lancer in taking down Saber, bullets once again came from the end of the corridor.

Volumen Hydrargyrum still loyally blocked this attack for Kenneth.

Kenneth turned to look, only to see that Kiritsugu Emiya, who had supposedly fled, had actually returned.

He stood at the end of the corridor, firing his gun.

“A foolish little mouse… how dare he return?”

Seeing Kiritsugu Emiya flee, Kenneth had originally intended to ignore this despicable and annoying little mouse.

He never expected the other party to dare to return and shoot?

This was simply mockery of him.

Furthermore, a despicable person who attacked with such contemptible and vulgar means as firearms was utterly unworthy of being a Magus.

Intense killing intent surged within Kenneth once more, and he decided to deal with this annoying little mouse first, and then, with Lancer’s cooperation, take down Saber.

“Lancer, I’ll leave this battlefield to you.

I'm going to kill that gray rat that only deserves to live in the sewers.

Volumen Hydrargyrum, track and eliminate.”

At Kenneth’s command, most of the Volumen Hydrargyrum flowed like a jellyfish to his feet, while a small portion of Volumen Hydrargyrum extended thin tentacles and scattered, transforming into tracking signals to prevent Kiritsugu Emiya from escaping again.

Kenneth stood atop the Volumen Hydrargyrum, controlling it to swiftly pursue Kiritsugu Emiya, a sneering smile playing on his lips.

In his mind, he had already envisioned how he would dismember Kiritsugu Emiya with Volumen Hydrargyrum once he caught him.

Seeing Kenneth pursuing him, Kiritsugu Emiya endured the side effects of using “Time Alter” and desperately weaved through the corridor.

“Time Alter” is not a primary Magecraft that strengthens the body, but rather a Magecraft that can sever the time within a specific space from external time, achieving a certain “manipulation of time.”

The Emiya Family had generations dedicated to researching time manipulation Magecraft, and the Magecraft Crest on Kiritsugu Emiya's back was inherited from these generational research achievements.

“Time Alter” was Kiritsugu Emiya's unique Magecraft, capable of “adjusting” brief moments of time.

When Kiritsugu Emiya used “Time Alter,” he could achieve a level of physical prowess impossible for ordinary people.

It was precisely by relying on “Time Alter” that Kiritsugu Emiya dodged Kenneth’s mercury blade net attack.

However, using “Time Alter” placed a considerable burden on Kiritsugu Emiya’s body.

Even using only “Double Accel” of “Time Alter,” Kiritsugu Emiya still felt his body ache as if it were about to split open.

But he knew it was all worth it.

The gap between a Servant and a Master was enormous; only by drawing Lancer away from Kenneth could he have a chance to deal with Kenneth, or even eliminate him.

After turning several corners and seeing the mercury used by Volumen Hydrargyrum for tracking, a slight smile also appeared on Kiritsugu Emiya’s lips.

He knew that Kenneth, overly confident in himself, was stepping into the trap he had prepared for him, one step at a time.

Feeling the time was right, Kiritsugu Emiya leaped out from behind a concealing wall and once again fired at the pursuing Kenneth.

Volumen Hydrargyrum still precisely blocked Kiritsugu Emiya's shots, its deployed defensive film once again stopping all bullets, just as before.

“A foolish trick, a mere buffoon! Can’t you see that your pathetic attacks are useless against me?”

Kenneth, hidden within the defensive film, couldn't help but burst out laughing.

But he didn't know that the opponent he was mocking had already discerned the weakness of Volumen Hydrargyrum's automatic defense.

Through several probes, Kiritsugu Emiya had already understood Volumen Hydrargyrum's defensive mechanism, knowing that Volumen Hydrargyrum's speed primarily originated from pressure.

Volumen Hydrargyrum could rapidly expand under pressure to form a defensive film, but it could not quickly revert from a film state to its normal state.

Therefore, once Volumen Hydrargyrum deployed its defense, it could not immediately deform to deploy stronger defenses against a sudden increase in attack power.

So, before the submachine gun's bullets were depleted, Kiritsugu Emiya pulled out another pistol from his embrace.

The “Contender” large-caliber pistol, whose bullet speed was more than two and a half times faster than before, and its destructive power was seven times greater.

The only drawback was that this pistol's magazine held only one round, requiring a reload after each shot.

As the bullet fired, the mirror-smooth defensive film could not withstand the sudden immense pressure and was pierced, creating a hole.
