Rozen's gaze fell upon a side wall deep within the church.
There, embedded in the monastery's wall, was a carved sculpture.
It was a metallic relief.
It looked only about two or three square meters in size.
The patterns carved on it were somewhat abstract, making it difficult to understand what it was trying to express.
However, in the midst of it all, one could seemingly discern the silhouette of a woman.
She was a young and exotic-looking beauty.
Rozen was captivated by this mural.
Moreover, he was drawn to it immediately upon entering.
La Folia seemed to feel the same way.
"Do you also find that mural a bit strange?" La Folia, seemingly satisfied with Rozen's observation skills, wore an appreciative expression while raising doubts.
"But, although I feel something odd about it, I can't pinpoint what's wrong, so I thought it was just my imagination," Rozen nodded in agreement with La Folia's words.
In fact, Rozen felt the same way, sensing something strange about the mural but unable to articulate what it was, almost thinking it was just his imagination.
For this reason, Rozen even used Spirit Vision to observe, and it seemed that he sensed the flow of magic.
However, for some reason, this magic felt both crude and obscure, giving a vague feeling.
"Could there be some kind of seal or barrier acting here?" La Folia suggested this possibility.
"It's not impossible," Rozen didn't deny this point.
Even with Rozen's abilities, if there were barriers or seals nearby, he definitely wouldn't overlook them, but this was relative.
For example, some barriers and seals were extremely intact, and their operation was still normal, so Rozen could naturally see through the spells and magic and expose them.
However, some barriers were close to stopping their operation, and some seals were already crumbling and incomplete. After being specially hidden, even Rozen might not be able to uncover them in a short time.
Rozen didn't know if this was the case here, but one thing was certain: this monastery was definitely not as simple as it appeared on the surface.
There was a secret sleeping here.
And that secret...
"It's in that mural, isn't it?" La Folia revealed this truth.
And, a deep interest flickered in her eyes.
"Do you have a way to unravel the secrets here, Nichiyo?" La Folia inquired Rozen.
It was both a probe and a test.
Rozen could feel that the girl named La Folia was intending to test his abilities.
No, not just his abilities, but also his character, temperament, the importance of his existence, and even his will. La Folia seemed prepared to test and understand everything about Rozen, as if provoking him.
Rozen glanced at La Folia and smirked.
"As long as there is enough time."
When Rozen said this, his tone was full of confidence.
Obviously, Rozen was confident that he could unravel the secret sleeping here within a certain amount of time.
Is that strange?
One should know that in Rozen's mind, knowledge has accumulated to a terrifying extent.
Inside, there is knowledge of all summoning rituals from ancient times to the present.
Inside, there is the wisdom of numerous jujutsu systems from ancient times to the present.
Inside, there is a library-level magic reserve accumulated over two thousand years by the Mage's Association.
Inside, there is research and collection of the demon sanctuary in this world since his childhood, as well as the accumulated magical technology of the Lion King Agency.
It can be said that with Rozen's current level of knowledge, even a small fraction would be enough for others to become great mages or jujutsu users.
And Rozen even possesses the power of the divine obtained by Odin, who exchanged knowledge of runes from the Well of Wisdom at the cost of one eye.
With all these mysteries combined, if Rozen still couldn't unlock the secret here, that would be unprecedented.
So, it won't take too long.
"With half an hour, I should be able to see through this place," Rozen gave a very clear answer.
"Very well."
La Folia looked at Rozen like she understood something, smiling brightly.
"You truly live up to being the younger brother of the Witch of the Void, who sealed the Fourth Primogenitor and once descended with immense divine aura as the Divine Child. I sincerely admire your character, ability, and will."
As if only now acknowledging Rozen, La Folia smiled very happily.
However...
"It seems like you've attracted quite a bit of trouble, my princess."
Rozen slowly concealed his expression, as if sensing something, and sighed.
"Oh?"
For a moment, La Folia seemed to not understand what Rozen meant, but then she raised her eyebrows prettily and looked in the direction of the door.
"Senpai..."
At this moment, Yukina also snapped out of her happy state, driving away the cats beside her, picking up her guitar case, and coming to Rozen's side with a serious expression on her face.
The three of them looked towards the direction of the door together.
Soon, they heard a tumult of footsteps approaching rapidly from afar.
"Here they come!"
Rozen, Yukina, and La Folia raised their eyes simultaneously.
The next moment...
"Boom!"
With a blast, the church's doors were blown down by explosions, along with the surrounding walls, all blasted away.
The blast wind was like a terrible pressure, blowing away most of the church and shattering the dilapidated benches.
Soon, the explosion engulfed the location of Rozen and his group.
Unfortunately, the incoming blast wind and explosions were all isolated.
Because Rozen extended a hand, and an invisible barrier spun out, blocking in front of him and his companions, deflecting the incoming blast wind and explosions.
But that was just the beginning.
Before long, countless figures surged in from the blown church doors.
They were soldiers covered in black armor from head to toe, carrying large machine guns, and even wearing black helmets on their heads to conceal their entire bodies.
"Click! Click! Click!"
The sound of machine guns rang out, as numerous black soldiers raised their guns towards them.
Then, without hesitation, the soldiers pulled the trigger.
"Bang! Bang! Bang! Bang! Bang!"
Under the hail of bullets, a barrage of bullets formed.
Bullets poured down mercilessly on Rozen, Yukina, and La Folia.
