Unlike the weathered cave outside, the interior of the ruins is a finely polished and exquisite stone chamber.
Near the entrance, there are debris from explosive rock layers, but inside, there is no damage.
The interior of the stone chamber doesn't bear any artifacts to discern its age or culture, making it difficult to determine how long it has been resting underground.
Despite being an underground tomb, the place emits a faint light from the stone walls, lacking any eerie atmosphere but rather exuding a sense of sanctity and solemnity.
This place, more than being a tomb, resembles a temple.
Led by Gajou, a group of young boys and girls steps into it, reaching the third floor.
Here, Liana awaits them as if she has been waiting for a long time.
"Everyone, please look."
As soon as everyone enters, Liana immediately points to herself.
"This is the entrance to the 'Fairy's Coffin.'"
Liana's words make everyone lift their heads and look ahead.
Rozen does the same, glancing up to see a more solemn door of the stone chamber.
However...
"Is this door really that formidable?"
Kojou is quite puzzled, observing the plain door in front of him.
To this, Rozen can only say,
"I'm afraid this door is not the entire seal."
"Ho?"
"..."
Gajou and Liana, one curious and the other serious, both look at Rozen.
"Not the entire seal?"
Kojou, on the other hand, seems a bit puzzled, apparently not understanding Rozen's words.
Rozen then surveys the surroundings.
Just with a glance, Rozen grasps the situation.
"The entire structure of these ruins is the essence of the seal."
Rozen calmly states this fact.
"The builders turned the entire temple into a seal. To unlock it, you not only need to figure out how to deal with the door in front of you but also analyze and study the spells operating throughout the entire ruins."
This is why so many experts couldn't open this seal.
If they only focused on studying the door in front of them, it would be impossible to break the seal.
To open the seal, either the sealing spells throughout the entire temple need to be unraveled, or there must be a method to unlock the seal; otherwise, the only option is to forcefully destroy it.
Naturally, attempting to forcefully break the seal requires blasting the entire temple; otherwise, the seal will continue to operate, preventing anyone from entering.
Moreover...
"As long as there isn't a power capable of destroying the entire temple, this door cannot be shaken."
Rozen, relying on his vastly improved knowledge and perception, discerned all these secrets.
He then looked at Liana.
"If you don't believe it, Miss Caruana, you can summon your beast vassals and try to see if they can destroy this door."
Rozen said this with a slight smile directed at Liana.
This made Liana furrow her brows, feeling somewhat underestimated.
You see, she is a noble of the Warlord Dominion, a pure-blood vampire who has lived for centuries, and, although not comparable to those who have lived for much longer, she still belongs to the so-called old generation.
Moreover, being the first progenitor's blood lineage, even as a third-generation elder whose descendants are from an unknown distant time, she is still pure-blooded, with strength far beyond the reach of ordinary demons and humans.
At least, if Liana were to summon her beast vassals, not only could they destroy a single door, but they could obliterate everything in the vicinity in an instant, burying everyone here.
It is precisely because of such formidable power that Liana dared not release her beast vassals in front of the door, fearing that things inside might be affected. Otherwise, in a situation where there seemed to be no other way, people here would surely try to use explosive methods to enter.
The crowd had confidence in the power of Liana's beast vassals, which is why they didn't utilize them to break the seal earlier.
Now, Rozen, seemingly indifferent, said something that stirred a sense of struggle in Liana.
If it were someone else, Liana might not feel this way.
However, considering that the other person might be the brother of the Witch of the Void, the hateful and detestable demon killer's family, even if she didn't want to offend the witch, Liana didn't want to be underestimated.
At this moment...
"Come forth!"
Liana shouted loudly.
"Sköll! Hati!"
As this call echoed from Liana's mouth, astonishing magic was released from Liana.
That is the power possessed by old-generation pure-blood vampires, accumulating magical energy since birth.
This magical power effortlessly stirred the atmosphere and ignited on Liana's body like dim flames.
In terms of magical quantity alone, it was undoubtedly a level unattainable for humans.
Even Rozen, without activating the Crimson Wing Formation, couldn't easily prevail against this magical power.
In this situation, the magical power released from Liana formed two fierce beasts.
They were giant wolves with golden and silver luster, each about three to four meters long, formed by dense magical energy.
"Howl!"
"Howl!"
The two giant wolves appeared on Liana's left and right, raising their tall bodies and howling.
The howls directly lifted the atmosphere, turning it into a raging wind that surged.
"Oh...!"
Seeing this scene, Gajou was not shocked but rather delighted, making a somewhat chaotic sound.
"Miss Liana...!?"
Kojou, completely unprepared for Liana to possess such astonishing power, was blown away by the gust of wind during his astonishment.
As for Rozen, he had already quietly retreated to the rear when Liana released the suppressed magical power within her.
"Is this the beast vassal of an old-generation vampire noble?"
Looking at the two giant wolves that stirred up a hurricane, Rozen's eyes gleamed.
In the past, although Rozen had seen the beast vassals of vampires, he had never seen the beast vassals of pure-blood vampires.
Now, seeing the beast vassals released by Liana, Rozen immediately made a comparison.
"Indeed, they resemble my familiars."
Both were aggregations of magical energy, differing only in the degree of materialization.
When Rozen summoned his familiars, the external materialization was one hundred percent, fully tangible. Therefore, they could bleed when cut by a sword, die when their heart was pierced, and then instantly transform into magical energy.
Vampire beast vassals, on the other hand, were semi-materialized, neither bleeding nor having vital points vulnerable to conventional attacks. Strong magical power was needed to suppress them.
Given this, the appearance of vampire beast vassals varied widely, but they invariably had a completely transparent body, as if formed by crystal or glass.
Naturally, crystals and glass were fragile materials. Although they could withstand weaker magical power, they would be instantly annihilated when facing stronger magical power.
In contrast, complete materialization allowed Rozen's familiars to continue fighting even if injured.
Therefore, each had its own strengths and weaknesses.
However, there was one thing in common between the two.
Even if their external form was scattered, they would only return to the host's body, consuming magical energy, and could continue to be summoned.
Seeing the beast vassals of the pure-blood vampire, Rozen immediately understood.
"The strength of those two wolves is probably much greater than the Wyverns."
It's worth noting that the Wyverns are considered exceptional among upper-level familiars. They are a type of dragonkin, which indicates the formidable power of Liana's beast vassals.
And Liana, who had become Rozen's object of comparison, issued an order.
"Go!"
At Liana's command, the semi-transparent golden and silver giant wolves suddenly turned into two flashes, violently slamming into the door.
"Boom!"
A resounding noise echoed.
