The person who infiltrated the army is naturally Rozen.
As Rozen watched Mash battling the group of wyverns, his mind raced, and he quickly made several judgments.
"Although they are Phantasmal species and dragon-type, they're only wyverns, likely falling under the category of magical beasts."
Phantasmal species are also divided into different ranks.
From low to high, there are magical beasts, mythical beasts, and divine beasts.
Generally speaking, the Phantasmal species that exist in this world are magical beasts, having been around for about a century. While their existence itself is quite mysterious and tempting to magus, they are not invincible. As long as they aren't too weak, any Servant can handle them.
Mythical beasts are more challenging to deal with. Even top-tier Servants must utilize powerful Noble Phantasms and give their all in battle. These beings of mystery have largely disappeared to the inner world of the planet; they no longer exist in this world. Otherwise, magus would undoubtedly pursue them relentlessly, seeking to witness the miracles passed down from ancient times.
And then there are divine beasts, the terrifying beings mentioned in various mythologies and legends.
For instance, the Norse apocalypse wolf, Fenrir.
Or the King of All Beasts from Greek mythology, Typhon.
And the heavenly disaster divine beast from Mesopotamian mythology, the Bull of Heaven.
These are beings that not even top-tier Servants can necessarily defeat. Even if they can defeat them, it would still be a close victory that pushes them to the brink of death.
Among these various Phantasmal species, dragons are at the pinnacle.
If the dragons in front of Rozen were true dragon-type creatures, then with just Mash as his sole Servant, it would be impossible to gain such a dominant advantage.
Fortunately, these dragons are only wyverns, not true dragons. They fall under the category of magical beasts.
For ordinary magus, dealing with such creatures would indeed be extremely challenging.
At least in Rozen's view, these wyverns were almost like Upper-level familiars. If he had to face them alone, handling one or two might be possible, but against so many wyverns, escape would likely be the only option.
However, in the hands of a Servant, these wyverns weren't as formidable.
Currently, Mash had achieved a decisive upper hand, crushing the wyvern group effortlessly.
Watching wyvern after wyvern fall under Mash's attacks, Rozen couldn't help but feel a sense of anticipation.
"These are Phantasmal species, and they're only wyverns."
For ordinary magus, even obtaining a scale or a fang from such creatures would make for precious magical materials. If one could tame them as familiars, they would become top figures in the world of magic.
For Rozen, that was something equally alluring.
Of course, compared to magus who would go mad just at the sight of these mysterious creatures, Rozen was relatively rational.
After all...
"In the 'Summoning Arts' that I've studied, there's a ritual for Summoning Wyverns."
However, that ritual was for summoning Upper-level familiars.
In other words, Rozen hadn't yet mastered that magic.
Originally, in order to summon Upper-level familiars, Rozen had been sifting through various rituals that allowed for such summoning. He intended to select the most suitable one as his research subject and attempt to master it.
Now, upon seeing these wyverns, Rozen decided.
"I'll choose wyverns as the first Upper-level familiars to summon."
In other words, Rozen was thinking...
"I should first learn the ritual for Summoning Wyverns."
For this reason, Rozen believed it was necessary for him to obtain a wyvern's corpse or perhaps even tame a wyvern.
In this way, it would definitely be greatly beneficial to Rozen's research.
At that moment, Rozen gave a direct order to Mash.
"Mash! Capture a live one!"
This instruction not only caught Mash off guard but also alerted the surrounding soldiers to Rozen's presence.
In the next instant...
"Who are you!?"
The French Marshal, who had been immersed in sorrow, immediately flashed a sharp gaze, raised his sword, and moved toward Rozen.
The surrounding soldiers also surrounded Rozen one by one, their faces filled with caution.
Although surrounded by armed personnel, Rozen remained calm. He raised his hand in a relaxed manner, signaling his surrender.
"I am not your enemy."
Rozen looked at the French Marshal and smiled suddenly.
"Can you ask your subordinates to lower their weapons? Marshal Gilles de Rais."
Gilles de Rais.
When this name came from Rozen's mouth, the surrounding troops didn't relax their vigilance. Instead, hostility emanated from them.
"...Do you know me?"
Gilles de Rais stared at Rozen intensely, his voice low.
In response, Rozen calmly spoke.
"Of course, I know you. After all, you're a noble of France, a renowned military figure who aided Jeanne d'Arc in recapturing Orleans years ago. You've been hailed as a hero by the people of France and even received the highest military honor, the title of 'Marshal.' How could I not know you?"
As he said this, Rozen added silently in his mind.
"I realized it was Gilles de Rais when I used 'Heaven's Eye' to observe the army's movements and saw you mention 'Jeanne.'"
Because Gilles de Rais was one of the earliest French commanders who followed Jeanne d'Arc. He was also one of the few trusted and close friends of Jeanne, someone she could rely on completely. They were partners who had each other's backs.
If we were to consider who had the deepest connection with Jeanne d'Arc in her lifetime, it would undoubtedly be this Marshal.
Therefore, after Jeanne's capture, Gilles de Rais descended into madness completely. He withdrew to his estates in Marshkael and Tiffauges, immersing himself in alchemical research, hoping to discover the secrets of alchemy through blood. He tortured and killed over three hundred children for this purpose, which ultimately led to his execution by burning at the stake.
However, now it seemed that Gilles de Rais hadn't fallen completely into madness. Even though there was a faint air of darkness and hostility around him due to Jeanne's death, he hadn't yet completely succumbed to evil. He would likely begin to resent unjust gods and curse them in the future, but for now, he appeared normal.
Rozen seized upon this and spoke to Marshal Gilles.
"Anyway, we'll help you drive away the wyverns first. After that, we can have a proper conversation. How does that sound?"
With that, Rozen gestured toward Mash's direction, making sure that all the soldiers could see the heroic scene of Mash fighting.
This gesture conveyed that they held no hostile intentions and that even if they were to engage, Gilles and his forces wouldn't stand a chance against a Servant who could easily vanquish wyverns.
Facing a Servant who could easily crush even wyverns, regular military forces naturally had no means to retaliate.
As a well-known Marshal, Gilles couldn't possibly be unaware of this fact.
"...I understand."
Gilles de Rais lowered his weapon and signaled for everyone to do the same, speaking in this manner.
"I'll trouble you to assist us. Once the dragons are driven away, as long as your requests aren't too excessive, I'll fulfill them."
Hearing this, Rozen finally nodded in satisfaction.
