Use FGO to open the second dimension

"Hey! Sexual harassment uncle! What are you doing?" A hint of violence appeared in Ritsuka's eyes.

In fact, she is also a dangerous person, but compared to the servants, Ritsuka is too weak.

"Anyway, let's ask about his situation first. He seems to be a normal Heroic Spirit."

Suddenly, a projection emerged, with a figure that looked very weak in it.

"Hey, there's a guy who's very easy to talk to. How did you do that? Is it through some magical communication method?"

Cu Chulainn suddenly showed a look of curiosity.

"Nice to meet you, Servant of Caster. Although I don't know which Heroic Spirit you are, I still hold you in awe."

"Ah, forget about this kind of opening remarks. I'm tired of hearing them. If you have something to say, just say it quickly, you weakling. You are better at this, right?" Cu Chulainn waved his hand and said lightly.

However, while speaking, Cu Chulainn glanced around and then couldn't help but curl his lips.

The master and servant pair left... although I had expected them to do so.

After all, we just met, and it is unlikely that they would be willing to travel with me so easily.

"Hmm... yeah... really? Then let me ask you... you're a weakling... you're a weakling, and you're being called that on our first meeting..."

Dr. Roman couldn't help but look shocked and said so.

Chapter 4 Remlia vs. Shadow Berserker

"...This is the current situation in Chaldea. Ritsuka is currently conducting field research as a Master."

Dr. Roman said this after he finished explaining and began to ask about the current situation.

"I'd like to confirm, are you the only Servant who participated in the Fuyuki Holy Grail War and survived?"

"If you mean winning or losing, I didn't lose. But at some point, our Holy Grail War took a different turn."

Having said that, a trace of solemnity appeared on Cu Chulainn's face.

"I don't know the whole story. The city was engulfed in flames overnight, and all the humans disappeared, leaving only the Servants. Saber was the first to reignite the Holy Grail War. She provoked conflicts everywhere like a duck to water. Then she personally dispatched Archer, Lancer, Rider, Berserker, and Assassin."

"A battle for survival among seven Servants... These are the rules of the Holy Grail War held in this city."

Olga Marie explained to Ritsuka who was standing beside her. Strictly speaking, Ritsuka was still a novice.

"It's the Servant who won this fierce battle... No, to be more precise, it's the Servant who survived this war."

Mash continued.

"Yes. And then, the Servants defeated by Saber will be contaminated by the black mud, just like those two just now. Those guys, along with the monsters swarming out like maggots, seem to be searching for something. And the trouble is, they're looking for me. Because as long as I'm destroyed, this Holy Grail War will not end."

Having said that, a hint of embarrassment appeared on Cu Chulainn's face.

"The only servants left are Saber and you...if you defeat Saber..." said Dr. Roman.

"Well, then the Holy Grail War will be over. However, whether this place can be restored to its original state is unknown."

Cu Chulainn shrugged his shoulders. This matter was not his business, and he didn't know about the incident.

"What? Even though you helped us, it wasn't for yourself in the end. You wanted to defeat Saber. But you had no chance of winning on your own, so you came to us... Am I right?" Olga Marie was unhappy.

Although she could resolve this singularity, the other party's actions made her feel a little unhappy.

"That's right. But it's not a bad thing, is it?" Cu Chulainn admitted very frankly, then glanced around.

"Anyway, you see, we have a visitor."

Suddenly, many dark shadows appeared from nowhere and began to approach the few people.

"Ah...!" Olga Marie immediately hid behind.

"They will keep pouring out. So, of course, the more companions the better!"

As Cu Chulainn said this, he waved his right hand, and several runes turned into flames and rushed towards the black shadow in front of him.

Mashu also looked alert and rushed forward. Although it was difficult to deal with the shadow servants, she could still deal with the monsters.

This is the location of the burnt forest. Honestly, Koizumi doesn't know where Remlia wants to go. In Koizumi's opinion, she is just wandering around aimlessly. But is it really okay to wander around like this?

Koizumi felt that he couldn't go any further, or else something would happen. He always felt there was danger ahead.

"Miss, are you sure you want to go forward?" Gu Quan couldn't help but ask, a hint of worry in his eyes.

"Of course, but it seems you've already sensed the presence ahead. Yes, there's a very strong guy up ahead, and I'm planning to go and meet him." Remlia seemed very confident as she slowly flew down from Koizumi.

"You don't need to get close. This enemy is not one you can approach. At least I don't have the energy to protect my servants in the next battle. This enemy... is very strong..."

There was a cold murderous intent flashing in Remlia's scarlet eyes. If she was not mistaken, the enemy in front of her was divine and its strength was probably not much weaker than hers. If a real fight broke out, it was still unknown who would win and who would lose.

However, Remlia is never afraid of the enemy in front of her, and she will challenge him no matter how strong he is.

"Roar"

A roar suddenly rang out, as if someone had sensed someone had intruded into their territory. The next moment, the ground shook, and a gigantic figure rushed out. Even though it was enveloped in a shadowy black mass, Koizumi could still see its features, and that was why he was shocked.

He was a sturdy man who was at least two meters tall, with messy black hair, well-developed muscles, and a very strong body. He wore an armored battle skirt, held a ferocious axe and sword in his hand, exposed his upper body, and was barefoot.

With the appearance of this sturdy and powerful man, a ferocious aura like that of a ferocious beast suddenly emanated from him, instantly covering the surroundings and making Gu Quan subconsciously feel suffocated.

This is Berserker, a true berserker.

"Back off!" Remlia shouted at Koizumi with a serious face. Then, Remlia carried her petite body and walked towards the giant in front of her, who was a huge contrast to her.

The giant swung at her, but Remlia didn't dodge. In the blink of an eye, a spear wrapped in pink light appeared in her hands. The moment the axe and the spear collided, an unexpected scene happened. Although Remlia looked very tired, she did not retreat at all. Instead, she blocked the attack.

A wave of energy erupted from it, and Koizumi quickly stepped back. Just by looking at her, he could sense Remlia's extraordinary power.

Although her strength was inferior to that of the other party, Remlia was able to barely contend with the other party due to the blessing of the vampire in the dark, but——

"They're quite strong. The Berserker class truly lives up to its name. However... if they were Berserkers, they'd lose their sanity due to their frenzy, and wouldn't necessarily be able to react quickly during battle!"

Thinking this, Remlia shook off the giant in front of her, and then used her agility to deal with the enemy.

But what surprised Remlia was that the giant in front of her was not at all inferior to her in speed.

"You must be kidding... Such a huge body can actually move so fast!"

Remlia's scarlet eyes suddenly shrank, and then she could only grit her teeth and attack the enemy in front of her frantically.

Slash, slash, and slash again...

The giant in front of him would only use this one move once he got close to the enemy, but it was more useful than any other move.

Because the giant in front of him is a powerful type, but the key is that not only is he extremely strong, but his speed is also not inferior.

However, it seemed that because he had turned into a shadow, his strength had decreased to a certain extent, which made Remlia in front of him qualified to fight with the opponent.

While dodging the opponent's attacks, Remlia continued to swing Gungnir to fight back.

The beast-like attack of the giant in front of her made Remlia feel a bit awkward.

This kind of pure attack is difficult to deal with when facing the huge axe sword.

It caused a terrible gas explosion, which turned into a terrifying energy storm and fell heavily on Remlia.

Remlia gritted her teeth secretly and held Gungnir horizontally in front of her body, but the opponent was so strong that Remlia was still knocked away by this blow.

"Such a terrifying power..." Remlia thought that as a vampire, with the blessing of the night, her strength was already strong enough, but facing the power of the giant in front of her, she still felt a sense of danger.

But, it's only interesting this way, isn't it... Remlia's mouth curled up slightly, her fighting spirit had been aroused.

In Gensokyo, due to the constraints of the spell card rules, I couldn't even have a good fight. Now that I have met an opponent, how can I not enjoy it? It has been a long time since I met an opponent of this level.

Thinking of this, Remlia raised a dangerous smile at the corner of her mouth and walked towards the giant in front of her without hesitation.

He kept waving the Gungnir in his hand. Although the opponent's strength and endurance were very high, it did not mean that he could not cause damage to him. As long as he could cause damage, he would have a chance to kill the opponent.

"Roar----"

The giant roared and swung the giant axe in his hand towards Remlia indiscriminately.

The power of the blow mixed with the air-breaking blow was enough to make people despair, but Remlia showed a cruel smile, then jumped up from the spot, dodged the giant's axe at lightning speed and rushed to the high air behind the giant, then attacked straight down.

However, the giant reacted quickly, and his other fist went straight to Remlia's chest.

Remlia ignored the giant's attack and took his punch head-on. She endured the severe pain and struck out like lightning, her sharp nails piercing the opponent's heart.

Vampires have extremely strong vitality. Even if their bodies are blown to pieces, they can recover quickly, but it takes time.

It has to be admitted that the opponent's punch made Remlia's chest full of blood and even dented, but Remlia's attack also hurt the opponent.

The giant retreated quickly, and even though Remlia didn't hit his heart, she still grabbed a large piece of flesh.

"Miss!"

The moment Koizumi saw the blood on Remlia's chest, his expression changed.

But the next moment, Koizumi felt a burning sensation in his right hand. His face twisted and he looked at his right hand.

There were three blood-red marks there, and at the same time, the memory of this mark entered his mind.

“…Command Seals…”

Being able to help the young lady... That's what the young lady wants to do most right now... A fiery look flashed in Koizumi's eyes.

Slowly, Koizumi pointed the arm holding the three Command Seals in Remlia's direction.

"I give an order in the name of the Command Seal... Remlia Scarlet... eliminate the enemy before you!"

A Command Seal vanished, and a huge amount of magical power surged into Remlia's body. Remlia was slightly startled, and glanced at Koizumi behind her, and happened to meet Koizumi's eyes.

Remlia quickly withdrew her gaze, but the corners of her mouth rose slightly.

With a sudden rush, Remlia arrived above the giant and attacked him directly.

The giant roared and swung the giant axe in his hand towards Remlia.

Remlia showed no fear at all, but just shouted loudly as if complaining about her dissatisfaction in her heart.

“I’ve told you so many times! Don’t call me Remlia Scarlet! Call me Miss!

"However, I'll spare you for now, considering your loyalty to me! Open your eyes and watch how I kill this guy!"

"The vast killing array - the red city that never sleeps!"

Chapter 5: Invitation from the Alliance

"The vast killing array - the red city that never sleeps!"

Suddenly, a violent impact caused cracks to appear on the surrounding ground, and the chaotic cracks spread to the surroundings. Then, a bright red light like blood bloomed from her body.

The next moment, a massive bloody cross appeared from the ground. A red beam of light, formed entirely from concentrated spiritual energy, released a terrifying pressure. The giant man, trapped within the cross, roared repeatedly. The moment the red light ceased, Remlia flew backwards, blood in her mouth.

"Are you alright, miss?"

Koizumi's expression suddenly changed, and he quickly ran forward to help the other person up.

Although Remlia had blood in her eyes, the corners of her mouth were slightly raised, and her eyes were full of satisfaction.

"I won!"

Koizumi was slightly startled and quickly looked forward.

The giant in front of him was already soaked in blood, and his body had begun to turn into photons. It was obvious that this shadow servant had lost.

Koizumi couldn't help but breathe a sigh of relief, and at the same time, Remlia's wounds were slowly healing.

Just as Koizumi had speculated before, Remlia's greatest strength as a vampire is her vitality. Especially now, without sunlight, when the entire world seems shrouded in darkness, she will receive the strongest bonus from the field.

Seeing the red light rising into the sky, Cu Chulainn, who was trying to help Mashu use his Noble Phantasm, was also slightly startled.

Just when she had used her Mashu and was in disbelief, this red light caught her eyes.

"That... what is that?" Mashu couldn't help but look puzzled, and at the same time raised a trace of vigilance.

"It seems like the release of a Noble Phantasm."

"Yes, that should be the release of the Noble Phantasm. After all, with such magical power, it should be correct."

Cu Chulainn nodded, and roughly understood who was the person who released the Noble Phantasm there. However, what surprised him was that the direction that guy was heading in should be the territory of Berserker if he remembered correctly.

"That master and servant pair actually ran into Berserker's territory. Could she have slaughtered Berserker?"

Thinking of this, a hint of disbelief appeared on Cu Chulainn's face.

He had fought with Berserker before, so naturally he knew Berserker's real name. You know, even Saber defeated Berserker by relying on the terrifying level of her own magic power reserves.
