Use FGO to open the second dimension

However, dealing with familiars like these sea monsters is more than enough for both of them.

Especially Youmu, both her attack speed and movement speed are terrifying.

With an A+++ agility level, even Remlia would have a hard time catching Youmu if she unleashed it to her full potential.

They call it the fastest on earth in Gensokyo, and that's no joke...

These sea monsters were cut in half by Youmu's double swords before they could even react. These sea monsters only had this level of combat power, so no matter how terrifying their numbers were, it was only a matter of time to take care of them.

What's more, it's not just Youmu who's fighting, there's also Diarmuid...

With two Servants joining forces, few could withstand them, right? Koizumi knew this all too well.

Koizumi glanced at Mashu, who was standing beside him, and saw a look of deep hesitation on her face.

"Mashu, I know what you're thinking. For now, please don't get involved in the fight. It's most important to change your mindset. Seeing this scene, it's not that easy for you to completely let go, is it?"

Koizumi patted Mashu's shoulder and spoke slowly to Mashu's bewildered expression.

Mashu was slightly stunned, with a puzzled look on her face, and nodded slowly.

Indeed, she needed some time to calm down from what she had just seen.

"Pipe through that evil book! The demon-breaking red rose (GaeDearg)!!!"

Diarmuid tightly grasped the magic-breaking red rose (Gae Dearg) in his right hand, and without stopping, he transformed into a red meteor and stabbed out quickly. The scarlet spear tip flashed with an icy cold light and pierced the Prelatis Spellbook in Gil de Ray's hand quickly and accurately.

“Aa ...

As Gilles de Rey screamed frantically, the sea monster that had been summoned by the Prelatis Spellbook turned into a pool of blood like a bubble.

At the same time, Youmu revealed a cold smile, and a huge amount of magic power was completely released from his body.

"Now, I will offer you the full power of the Soul Potion Family's Life Two-Sword Style—Secret Skill: Westward Journey Spring Breeze Slash!"

Chapter 458 Rest in peace!

"Now, I will offer you the full power of the Soul Potion Family's Life Two-Sword Style—Secret Skill: Westward Journey Spring Breeze Slash!"

Youmu roared, and at the same time, the two swords in his hands - Bailou Sword and Louguan Sword - slashed down with lightning speed. The sword energy shook the air and overflowed. Even Koizumi, who was standing behind Youmu, felt the terrifying sword energy.

In just a moment, Youmu suddenly appeared behind Gil de Ray, and Gil de Ray seemed to be stunned. Two pink sword beams appeared on his back, and these sword beams turned into countless cherry blossoms, flying all over the sky.

It seems like this person is being given a flower burial.

Blood splattered everywhere, and after being engulfed by the pink blade light, Gilles de Ray's entire body was soaked in blood.

The attack just now was a sure-kill. There was no doubt that Youmu had hit the opponent's spiritual core. Although it seemed that he was only seriously injured now and would probably recover after treatment, it was impossible for him to recover if his spiritual core was shattered.

"Already killed!" After defining that this person was killed by him, Youmeng slowly put away his Bailou Sword and Louguan Sword.

Diarmuid's eyes were full of admiration. The sword he just struck was undoubtedly a perfect killing move.

If I were locked in by the opponent's sword, even if I didn't die in the battle, I would definitely be seriously injured.

Even I, looking at the sword skills that the other party just displayed, could not find any flaws at all.

Looking at the wounds on his body, Gilles de Ray's face was filled with anger, but also with a hint of relief.

"Ohhhh, is this mediocre ending also God's will..."

As his words echoed in the space, Gilles de Ray's figure slowly turned into photons and dissipated.

After glancing briefly at Gilles de Ray, who was slowly disappearing before him, Koizumi once again scanned his surroundings.

By the way, it seems that Caster's Master is not here. It seems that we have to find a way to find him.

"Master, it seems that Caster's Master is not here. Should we go find him?"

Youmu slowly came in front of Koizumi, a questioning look on her face.

After hearing this, Koizumi did not reply, but instead turned his gaze to El-Melloi II standing beside him.

After all, if we are talking about someone who is very familiar with the Master in this Holy Grail War, then it is undoubtedly El-Melloi II, so of course asking him is the best choice. I don’t know if he is a threat!

"His Master alone isn't a threatening magus... but even without Caster, he'll continue his rampage as a murderer if left alone. We can't let him go."

El-Melloi II had made it clear that Caster's Master must not be spared at any cost.

"Then we can't just leave it alone." Since El-Melloi II said so, there was no need for Koizumi to let him go. At the same time, Koizumi also roughly understood why Caster's Master was paired with Gil de Ray.

These two products are similar, no wonder they are put together, it would be strange if they were not put together.

"However, the key Caster has been defeated. In this way, the goal set by the supervisor should have been achieved, right?" Kenneth was obviously more concerned about whether he could get the Command Seals next. He didn't care about the rules of the surface world.

What's more, there are many murderers in this world, and the more important thing for him now should be the Holy Grail War.

"Indeed. Sir Kenneth, please proceed to the Fuyuki Church immediately and request additional Command Seals. We will stay here to handle the aftermath." El-Melloi II nodded, seemingly intending to take the opportunity to send the other party away.

"Okay, that's right. We really can't expose you to the supervisors."

Kenneth nodded slightly, then glanced at Koizumi and the others before speaking slowly.

"Well, see you later."

"Thank you all for your great assistance. I look forward to your continued support, future heroes."

Diarmuid thanked Koizumi and the others before leaving with Kayneth.

After seeing the backs of Kenneth and the others disappear, El-Melloi II turned his gaze to Koizumi and the others, and a trace of distress appeared on his face. It was obvious that searching for a murderer was indeed a bit troublesome.

"Alright, although searching here may make you uncomfortable, let's start looking for traces of the serial killer."

Just as Koizumi and the others were about to leave, Ritsuka looked distressed and glanced at Koizumi.

"Hey! Koizumi! Wait a minute!" Ritsuka called out to Koizumi in front of him, with a look of confusion on his face.

Koizumi was slightly stunned, his eyes fixed on Ritsuka, a hint of doubt in his eyes.

Slowly, Li Xiang's eyes occasionally glanced at the corpses of children scattered on the ground behind her. She couldn't help but feel a mixture of emotions. To be honest, she felt very uncomfortable seeing this, especially when she thought about how these children's bodies were actually thrown into the wilderness after their death. So...

If possible, Ritsuka hopes that Koizumi can allow these children to rest in peace after death.

Koizumi was slightly startled and sighed inwardly, knowing what Ritsuka was thinking.

Although Ritsuka was not as exaggerated as Mashu, it would certainly not be easy for her to recover after seeing this scene, especially when she thought about the children's bodies being abandoned in the wilderness, she must have felt very uncomfortable.

Cremating the bodies of these children is also a good option.

Thinking of this, Koizumi turned his gaze towards the corpses of the children in front of him and began to activate the power of his realm.

The power within his body, like a vast ocean, began to overflow, connecting to the deepest, whirlpool-like [Root Vortex]. This was the [Root Continuation] that Koizumi inherited from Yakumo Yukari. Although it was a bit of a waste of talent, every time Koizumi used the power of realm, it was like being familiar with Yakumo Yukari's power.

Yakumo Yukari's power is not so easy to fully master.

However, this level of power can still be used.

"The realm of burning and extinguishing!" The power of the realm surged, and with a wave of Gu Quan's hand, the corpses in front of him were instantly ignited, and the fire became more and more intense until all the corpses were burned to ashes.

"That's good. At least these children can rest in peace after death."

A look of relief appeared on Ritsuka's face, and a smile slowly appeared at the corner of his mouth.

"Well...senior is right..." Hearing this, Mashu nodded and smiled.

Immediately, Mashu's eyes turned towards the raging sea of ​​fire. The fear and terror in her heart seemed to be burned away by the fire. At the same time, she was praying for the children who died in the fire.

Youmu's eyes were cast at the sea of ​​fire in front of her, and her heart was calm.

As a half-human, half-spirit creature, she has witnessed the reincarnation of countless dead people in the underworld, and has become very indifferent to life.

Even if you see this scene, you will feel touched, but it will not be as exaggerated as Mashu and Ritsuka.

Koizumi stared at the sea of ​​fire before him, his heart finding a rare peace.

Chapter 459: Mysterious Assassin

After dealing with Gilles de Rey, Koizumi and the others began searching for the killer based on the clues left in the drainage pipes. Although it might seem troublesome, to be honest, Koizumi and the others didn't think so.

But—"Fu!"

Fufu, who was lying on Mashu's shoulder, seemed to have discovered something and let out a series of cries.

Koizumi also frowned slightly and looked forward, obviously noticing something.

Following Fu Fu's cry, Mashu looked up ahead and immediately revealed a look of surprise.

"Koizumi-senpai! Master! At the end of that road! Someone's fallen there!"

"That guy is already dead. His life force is long gone. I guess someone killed him..."

Slowly walking up to the other party, Koizumi's face didn't show much surprise. In a Holy Grail War like this, being killed by any means was a normal thing. Koizumi understood this the moment he saw the purgatory created by Gilles de Ray.

This is a war, and if it is a war, there will definitely be so-called victims.

Those children just unfortunately became victims of this.

And this guy in front of him is undoubtedly the Master if he appears here. After all, Gilles de Ray just wants the child. Gilles de Ray must have nothing to do after eating a lot to kidnap such a grown-up person.

"From the looks of it, this person should be the Master who summoned Caster."

El-Melloi II also said so, but then again, hasn't he seen Caster's Master?

Why else would it be this tone? What kind of words should it be?

Forget it. Even if you have participated in the Holy Grail War and know a lot about it, it is impossible to know everyone.

"...How could this happen? Did he have a falling out with his Servant?"

Mashu's face showed a deep surprise, as if the other party's death was completely unexpected.

That's true. The first thing that comes to mind is that he was killed by his own Servant. After all, there is no one else here except them. However, a quick glance at the wounds on the other party's body can roughly rule out this possibility.

"The knife wound on his body was clearly caused by someone with advanced skills. It's a bit strange to say that Caster caused it."

El-Melloi II was right. Judging from the knife wound, it certainly didn't look like Caster's doing.

Furthermore, given Caster's killing style, it's clearly impossible for him to kill someone so cleanly and quickly. After all, Koizumi hasn't forgotten the tragic plight of those children before, and such a clean and tidy method clearly doesn't suit Caster's aesthetic.

Of course, Koizumi has no interest in delving into the madman's aesthetic taste, as long as he knows that Caster didn't kill him.

This also means that someone had been here before, and there were no signs of a battle with Caster, which means—

It was very likely that the other party came here while he was fighting Caster on his side.

But - there is no one here, has the other party left?

No, if the other party killed Caster's Master, then it is very likely that they came for Caster. It is not reasonable for them to leave here without finding Caster. After all, as a magician, Caster knows more than just using the Master to provide magic power. It would be too strange to assume that Caster will die just because the Master was killed.

Judging from the knife wound, it was done by an experienced person, who must have a lot of similar experience.

So--

"El-Melloi II!" As if realizing something, Koizumi's gaze quickly turned to El-Melloi II.

At the same time, El-Melloi II seemed to have sensed something, and his magic power surged rapidly.

"Eight-door Golden Lock Formation!"

The formation activated, and a faint aura suddenly entered Koizumi's sensing range, but Mashu seemed to have not yet reacted. Even Fufu, who was perched on Mashu's shoulder, called out softly, with the expected hint of confusion.

"Lord El-Melloi!? What the hell…"

"Be careful, Mashu! This is a Servant's reaction!"

At this moment, Dr. Roman's voice suddenly sounded, which startled Mashu and made him alert immediately.

"Huh? But everything was just..." Although she was on guard, a hint of doubt still appeared on Mashu's face.

"It's the aura blocking. Assassin... without the Qi Men Dun Jia, we'd be in danger too."

At this point, El-Melloi II looked at Koizumi with admiration. "I didn't expect you to be able to detect Assassin's approach even when he was so well concealed. It seems my opinion of you needs to rise even higher."

In response, Koizumi simply rolled his eyes at the other person, a look of indifference on his face.

"I simply speculated based on his knife wounds that someone might be hiding here. After all, choosing to attack Caster's Master suggests a connection to the Holy Grail War. But the Master who killed Caster didn't pursue the victory to confirm Caster's destruction, but instead disappeared here. Clearly, something is amiss."

"This is just the most basic inference." Koizumi curled his lips and continued to focus his eyes on the front.

Li Xiang couldn't help but twitch his lips. The most basic inference? I always feel like I'm being looked down upon.

If I can't make this most basic inference, doesn't that mean I'm unqualified?

Of course, Ritsuka didn't say anything. She knew Koizumi had no ill will towards her and was just speaking casually.

"..." It was a Servant wearing a black combat suit and a red cloak. His face was wrapped in bandages under the hood of the cloak, completely covering his appearance. The figure of the man appeared silently.

"A group of people who use strange magic. I didn't expect you to be able to find me."
