Stone crouched in front of the stone wall, caressing each piece of granite, muttering words in his mouth, trying to figure out something like a mechanism. Concern is messy, what he does seems ridiculous, and I can't connect the impulsive and mediocre man in front of me with the dean of the Ayudin Academy.

As the sky grew brighter, the fog thinned, the wind blew in through the skylight, and I heard a slight movement, and in an instant, a sudden lightning bolt illuminated the dim and chaotic mind.

"That's ...... What was that! Lisa lifted her eyelids, her gaze quickly scanning every corner of the stacks.

She was one step ahead of me! I gasped. What an amazing glimpse, like the twinkling North Star in the night sky, I have never seen a woman with such a sharp gaze!

We all sat down to discern in detail, blah, blah, humble, subtle and vague.

"It's the sound of the wind blowing the window paper." Lisa whispered.

Stone looked back, "What window paper?" ”

"You nobles know very little about the lives of commoners. Living in a warm and sturdy castle, where every window is inlaid with bright glass to keep out the biting cold wind, window paper is a completely foreign commodity to you. ”

Lisa's choice of words was impolite, but her tone was calm, as if she were recounting a well-known objective fact, without any sarcasm.

"Civilians can't afford glass, and their windows are usually covered with a layer of translucent tissue paper, which is very ineffective in terms of lighting and wind. This kind of paper that sticks to the window is easy to break, and it makes a special whooshing sound when the wind blows, do you hear? ”

"How is it possible to paste window paper in the temple, I have been at Bromin College for decades, and I have never heard of such a thing." Kozmo suspected she had misheard, "I've experienced firsthand that it's easy to misinterpret tinnitus as a strange sound in extremely quiet environments, especially when you're preoccupied. ”

Lisa put her index finger to her lips and pleaded with the crowd to hold their breath. She closed her eyes, intently discerning the direction in which the voice was coming from, and walked forward step by step.

"Lisa, you're going to hit the wall." Stone couldn't help but remind her.

Lisa stopped suddenly, and she slowly raised her head—there was an irregular gap at the top of the stone wall of the ancient library!

Like a piece of sludge on a beauty's face, the notch not only destroys the overall beauty, but also reduces the strength of the stone wall. I think this must have been the intention of the temple when it was built, for there were no less than four or five similar gaps in the stone walls around the stacks.

I couldn't help but walk up to Lisa, stand shoulder to shoulder with her, look up at the strange gap, listen to the "sound of the wind blowing the window paper", and suddenly an inexplicable urge welled up in my heart. "Bart, can I step on your shoulder?"

"Willing to help." Bart walked over to the stone wall, got down on one knee, and bowed his head reverently.

I stepped on Bart's thigh and stood on his shoulder, less than half a foot from the wall. Looking closely, I could clearly see a small piece of translucent tissue paper sticking to the edge of the notch, trembling slightly, like a dead leaf in a cold wind.

I stood on tiptoe closer, and an abrupt burst of magic poured out of the gap and slammed into my face. I was hit with a strong impact, and the magic came at me like a stormy wave, drowning me entirely, throwing me high into the air, and mercilessly falling to the bottom of the sea.

My feet went limp, and I screamed and fell to the sky.

My father caught me just in time. I was in a trance, pointing to the gap in the wall and intermittently saying, "That's magic...... Where to flow...... I can feel it...... The temple is breathing......"

Jerome looked down and thought for a moment, put his index finger in his mouth, dipped it in a layer of saliva, and then stood on tiptoe, stretched out his arm, and approached the gap to feel the magic I was talking about.

He took a deep breath, and the next moment his breathing stopped abruptly, and the whole person froze, his pupils narrowed rapidly.

"The surging magic ran through the entire library like a stream of water, disappearing into the gap in the stone wall on the other side, and it was endless, and there was no trace of the source, and there was no end to it." Jerome exhaled his turbid breath sharply and returned to normal, and he said in a hoarse voice, "This is an experience I will never forget for the rest of my life, the temple suddenly came to life!" ”

Kozmo seems to realize something, "those gaps are ......"

"They were left behind by careful calculations at the beginning of the construction of the temple, and they are the 'eyes' of the magic array, and they are the key to the penetration of magic power. It is through the 'Array Eye' that the magic array is connected into an inseparable whole. ”

"In other words, as long as the magic power is blocked, it is possible to open the secret room?"

"I think that's exactly what it is." Jerome replied in the affirmative.

I remembered the rattling piece of tissue paper on the "Array Eye" and whispered, "That paper, they used paper to block the magic ......"

Jerome was stunned for a moment, he squinted his eyes and looked at the "virtual eye", and then used the tips of his index and middle fingers to carefully tear off the tissue paper.

"Hey, it's gone!" Kozmo couldn't hide his surprise and regret. That's the only clue, and if it is interrupted, the Chamber of Secrets will likely become a mystery that will never be solved.

Jerome was so well-informed that he rubbed it a few times with his fingertips and suddenly realized. "It melted into the spit. It is a piece of glutinous rice paper, which melts in the mouth, and is generally used to wrap high-grade candy to prevent the candy from sticking to the paper after getting wet. ”

"It seems that someone has climbed before us, they know the details of the magic array, they plugged the eyes of the array with glutinous rice paper, opened the secret room, and looked for what they needed. But it won't be the Bloodthirsty Bow. Without the support of the artifact, 'Kethera's Guardian' no longer exists. Lisa analyzed it in detail.

I was right, she's a thoughtful and intelligent person!

Jerome approved Lisa's speculation, adding, "I suspect that Carben's spies were also involved in this, blocking the flow of magic with glutinous rice paper and partially destroying Caythera's guards, which only Kaben's magicians can do!" ”

Father whispered a few words in Barth's ear, and then he left the library, the sound of hurried footsteps quickly moving away. I sighed secretly, a little worried. The secret is about to be revealed, but what is hidden in the secret room behind the stone wall?
