-957- [ Kaleid Blood ]

"Do you know what's inside?"

As Gajou spoke, pointing towards the cave ahead, Rozen's gaze had already followed suit.

Rozen naturally couldn't know what exactly was inside the ruins. However, earlier, he had used his Spirit Vision to examine the relic and sensed a formidable magical power dormant within, subtly concealed.

Of course, in this world, it's normal for ruins to have magical mechanisms, barriers, and protective spells to prevent malicious intrusion and destruction. It was expected for magical energies to flow inside.

Yet, within this particular relic, the dormant magical power gave Rozen a peculiar feeling.

That feeling...

(As if someone is calling out to me...?)

Rozen fell into contemplation.

This wasn't strange at all. Earlier, Liana and others had mentioned that the true identity of this relic was an underground tomb. Since it was a tomb, it undoubtedly contained the spirits of those who passed away long ago.

Perhaps, the spirits and lingering thoughts of the departed were still present, not yet dissipated.

And Rozen, being both a magus and an onmyoji, had unquestionable qualities in dealing with spiritual matters.

Even if he couldn't match up to shrine maidens in spirit communication, he surpassed ordinary spiritual abilities. Coupled with his exceptional Spirit Vision, he could sense the residual will and thoughts within.

Therefore, Rozen could affirm...

"There is something you all are looking for inside, right?"

Rozen spoke without hesitation, making Gajou squint his eyes slightly, gazing deeply at Rozen.

Following that...

"—Kaleid Blood."

Gajou suddenly mentioned this name.

However, it was precisely this name that made Rozen lift his head abruptly.

"You just said Kaleid Blood, didn't you?"

Rozen stared directly at Gajou, genuine surprise reflected in his eyes.

To Rozen's reaction, Gajou seemed quite satisfied.

"Indeed, someone from the Demon Sanctuary wouldn't be unfamiliar with that name."

Gajou said with a playful tone.

That's right.

This name wasn't just a name but referred to a specific entity.

It was a legendary being known almost worldwide.

"The legend says that besides the three existing Primogenitors, there is another one."

Gajou, in a tone full of amusement, revealed the contents of this legend.

"He is called the strongest vampire, surpassing the other three Primogenitors in power. He commands twelve Catastrophe-class Beast Vassals, has no blood relatives among the vampires, nor left any followers behind. He is a unique and solitary embodiment of terror."

Gajou stated confidently.

"Every time there's a crucial turning point in history, this strongest Primogenitor appears in the world, causing several global massacres and devastations. It's recorded in historical books, and events suspected to be caused by this Primogenitor are collectively referred to as 'Holy Slaughter'."

This was an event recorded even in the Holy Bible of the Western Church.

Among them not only appeared the embodiment of calamity, the strongest vampire Primogenitor, but also the ancestors of humans, demons, and even gods.

Therefore, whenever the term "Holy Slaughter" was mentioned, it immediately struck fear in people's hearts. Devotees might even kneel down in prayer, making it a profoundly evocative term.

"People generally refer to that existence as the Fourth Primogenitor, just after the three Primogenitors."

Gajou stared directly at the ruins, revealing a somewhat sinister smile.

"Although there's no evidence to prove the actual existence of this Primogenitor, it's treated as an urban legend. But don't you think, if what's inside is related to the Fourth Primogenitor, things would become quite interesting?"

Interesting?

Is this really interesting?

Rozen didn't think so.

After all...

"If it's just your wild imagination, that's one thing."

Rozen also looked at the ruins but with a changed expression.

"But since both the Warlord Dominion and the Japanese government are involved, jointly conducting this excavation, whatever is inside, even if it's not related to the Fourth Primogenitor, must be significant, right?"

This was the first thought that everyone who learned about the situation would have.

"No wonder the security here is so tight. You guys actually set your sights on a relic related to a Primogenitor?" Rozen smiled slightly and said, "You've got quite the courage."

Rozen gave this evaluation.

Gajou, on the other hand, didn't mind and spoke out.

"We call the thing inside 'Fairy's Coffin.' Its location, if not mistaken, should be on the third underground floor. That's also the last floor of this underground tomb."

Hearing Gajou's words, Rozen immediately understood.

"Let me guess." Rozen glanced at Gajou and smiled meaningfully. "When you investigated the third floor, you hit a snag, like a powerful seal at the entrance that couldn't be unlocked. So, you had to call Nagisa for help, right?"

"Smart." Gajou looked at Rozen in great surprise. "I thought you, looking the same age as my son Kojou and Nagisa, were surprisingly clever. Could it be you're like that eternal witch sister of yours? Looks young but is actually an old monster?"

"You're the one who looks like a delinquent uncle both on the outside and inside!" Rozen immediately retorted, then sighed, "You sure know me well."

When Rozen saw Gajou's reaction, he knew that this so-called archaeologist probably knew about his existence.

No, rather...

"As long as someone knows the 'Witch of the Void,' they would more or less be aware of your existence, right?" Gajou said with some joy. "The witch who kills without batting an eye adopted a little brother from who knows where. This matter is also quite well-known in the industry. To protect you, that little sister of yours has paid quite a price. You must be aware of that, right?"

At these words, Rozen's expression became slightly complicated.

This matter was naturally well-known to Rozen.

Otherwise, why would Rozen be so obedient to Natsuki?

Not out of fear, nor due to any strange quirks, but simply because he felt indebted to his sister.

In several lifetimes of Rozen's traversing existence, this time was undoubtedly the most dangerous and challenging.

At the same time, to protect Rozen, his sister, the witch, put in a lot of effort.

Therefore, Rozen had no choice but to go along with Natsuki.
