"Frey!?" Alan was instantly stunned when he heard the name, "He's there too?"

"Well, I guess he's right. "Because he and I arrived at the library at about the same time yesterday evening, except that I went to the second floor, and he was on the first floor...... I don't know much about the situation on the first floor, but I can guarantee that there is no one else on the second floor but me. ”

Allen's heart was instantly mixed. Thankfully, it wasn't anyone else who saw this, but Frey, and he would have done it as long as Cynthia told him to keep his mouth shut, but what made Alan worry was that the person who saw him and Cynthia together was none other than Frey.

"Hmm......" Alan nodded, remembering Will's reaction last night, and then realized that someone was following him, so he asked again, "And after that?"

"Then I saw you two circling the square several times, as if looking for something, and I didn't want to be discovered, so I went back to my room early. ”

"Hmm...... It seems that the person who was following him at the time was Frey. Alan thought. But after thinking about it, he felt something was wrong, "If it's Frey, then why didn't Will tell me directly?" ”

He looked at Alyssa again, she didn't look like she was lying, and she never did.

"Anyway...... It's better to think you didn't see it, or, better yet, forget about it. After thinking about it for a long time, Alan couldn't come up with a reason, so he gave up, "That book is a hoodoo, the farther away you are from it, the better." ”

"But didn't you just say that you went to see her tonight because ......of the book," Alyssa said hesitantly.

"Yes, she wanted to find the original manuscript of the book, though I don't approve of her very much. "Since Alyssa has seen everything, Alan simply said it all," she asked Professor Stabone in the afternoon to get the key to the revolving bookhouse. ”

"What is the Revolving Book House?" Riel was curious again.

"I haven't been there either, but I heard that it's in the basement of the library, which contains the original manuscripts of almost all the books. ”

"Ah...... If it's the basement, I think it's at the west of the stairs at the bottom of the library. "There's a little entrance to the underground, and there's an iron fence that's locked, I've seen it." ”

"It should be there. Alan glanced up at the bell tower, it was already seven fifty o'clock, and said, "Then I'll go first, you two go back to your room early to rest." ”

"Wait a minute!" but Alyssa suddenly stopped him, "I'm going with you." ”

"And me. Seeing that Alyssa was going to follow, Riel quickly added.

Alan was a little embarrassed, but still shook his head decisively: "No." ”

After saying that, he turned around and wanted to leave, but Alyssa grabbed his arm and looked at him with a determined look in her eyes, as if she had to go.

Seeing Alyssa's resolute attitude, Alan was a little hesitant. He wanted them to go with him a little, but remembering the danger of the book, he finally shook his head, sighed, and said, "This matter can't affect more people...... Especially the two of you. ”

The words seemed to have an effect, and Alyssa's hands were not so tight.

Alan noticed it, so he took her hand down and said, "All you have to do now is to go back to the room and rest, and if there is any new development, I will tell you as soon as possible tomorrow." ”

Then he turned to Riel and said, "Send her back." ”

"Hmm......" Riel originally wanted to go with Alan, but seeing that Alyssa no longer insisted, he reluctantly agreed.

By this time, the clock had already struck eight o'clock, and Alan didn't have time to say more, so he waved at them and walked in the direction of the library.

There was no one on the road, and he trotted all the way without much delay.

"You're late. As soon as he reached the steps under the main entrance of the library, Cynthia's voice immediately rang out.

Alan looked up and saw that she was looking at him with her back to a sycamore.

"It's rare to see you being late, it's not like your style. Cynthia said again, still holding a thick stack of parchment in her arms.

"Sorry...... Uh, it took too much time to eat. Allen said.

"Let's go, we don't have a lot of time left. Cynthia said and turned to walk west.

Alan hurried to follow.

Sure enough, as Alyssa said, in the westernmost corner of the staircase at the bottom of the library, there was a very hidden entrance to the underground. Looking down, it was so dark that I couldn't see anything clearly.

But fortunately, Cynthia was prepared, and she didn't know where to find a magic lamp, which could be regarded as illuminating the way down.

The two of them walked down the stairs as they carefully surveyed everything around them.

At first glance, the steps are also made of green bricks, but they are quite old, and the walls on both sides are covered with moss due to the dampness.

"Why build a basement like this in the library?" Alan asked, looking closely, "and it's weird that it was built without letting the students know?"

"Looks like you don't know anything about here. Cynthia smiled mysteriously, "But I don't blame you, after all, students are never allowed to enter here, and even I happened to see it in my grandfather's notes." ”

"Uh......" Alan was a little speechless.

"There's something you might be mistaken...... It's not a library that came first, and then it's here. ”

"What?" Alan didn't understand a little, but the next second he seemed to realize something, and he was shocked, and said, "Could it be ......?"

"That's right...... It was here that was first created, and then the current library was built on top of it. Cynthia explained slowly.

"So this place has been around for a long time?"

"That's right. Cynthia handed the magic lamp to Alan, and took out the key to unlock it, "At first, I thought that the missing treasure might be hidden here, but then I found out that this is a strange bookstore. ”

"Strange?" Alan wondered a little, "What's weird?"

"You can see this by looking at it, and I've only seen a simple description in my notes. So saying, Cynthia had opened the lock, and they took a few steps inside, and found that there was a small wooden door in the wall, which was a little tattered, but there was another lock on it.

Through the faint light of the magic lamp, Cynthia found the oldest of the keys in the whole bunch and carefully inserted it into the keyhole.

I heard a soft "click", and the lock was opened smoothly.

Cynthia gently pushed the door open, and a little dust shook off the door frame, but not as much as she thought. It seems that although it is off the beaten track, it seems that there are still people who come and go here occasionally.

"Who could it be?" thought Allen.

But before he could think about it, Cynthia had already walked in, and he had to hurry to follow. Then, as they closed the door, the whole room lit up in an instant.

"Ah......h But when he saw what he saw, he was completely stunned......

This room, which looks small from the outside, is incredibly spacious on the inside, almost the size of two common rooms. And when he looked up, he couldn't see the roof at all. What surprised him even more was that, unlike most of the rooms, this one was circular, and the walls clinging to the surrounding walls were rows of strangely shaped bookshelves, densely packed with books, and it was impossible to estimate how many there were.

The books on the two floors of the library already made him feel that he would never finish reading in this life, but seeing the scene here, he felt that not only in this life, but also probably two more lives may not be finished.

"Oh my God......" Alan looked up as he spun in place, stunned.

But when he stopped, he finally understood why this place was called the Revolving Book House...... Because all the bookshelves in the whole room are like rooms in a perpetual house, constantly rotating, but compared to the clutter there, this place seems to be orderly, only clockwise and counterclockwise, and slightly faster.

Cynthia was also surprised, but it was clear that she already knew what was going on, and after a little observation, she walked towards the center of the room.

There was something about a man tall, like a cup.

Alan also hurried over.

When he approached him, he realized that what looked like a cup was actually a pool of water, and it was filled with water.

"What is this?" Alan asked.

"Do you ask the name of this thing? I don't know. Cynthia stared at the pool and said, "But I know it can give me what I want." ”

Before Alan could understand what was going on, Cynthia had already begun to read something slowly.

"Listen to it...... Thou art ...... what I have seen."

It turned out to be the spell that summoned Heplus last night!

"What are you doing! Stop!" Alan was stunned, trying to interrupt her, for fear that she would call out something strange.

But Cynthia ignored him and only cared about herself.

Fortunately, until she had finished reciting all the incantations, the room was still quiet and nothing had happened.

Alan breathed a sigh of relief.

But now it was Cynthia's turn to wonder. I saw her staring at the pool carefully, frowning: "It's strange......"

"What's wrong?"

Cynthia circled the pool twice, and then said, "According to my grandfather's notes, if you read out some of the relevant contents of the book you want to find next to this pool, the original manuscript of the book should float up from the bottom of the water." ”

"I see, that's ......" Alan then understood what was going on, and his hanging heart was finally able to let go.

"But......" Cynthia was silent for a moment, as if she was recalling something.

"Could it be that you have recited some mantra by mistake?"

"No way!" Cynthia replied decisively, "I remember that spell very well...... And I just read it a total of three times, and I have carefully reviewed each time, and I can't get a word wrong!"

Things didn't go as she had expected, and Cynthia looked a little restless, and circled around the pool again, then hurriedly recited the incantation.

But to her disappointment, the water was still calm and normal, and nothing happened.

Cynthia was completely angry at this moment, and rolled up her sleeves to reach into the pool.

But at this moment, a thought suddenly flashed in Allen's mind, and he couldn't help but say: "Could it be ......?"

"What?" Cynthia asked after a pause. She knew that the things that Eren paid attention to were generally not ordinary.

"Uh, that's just my guess......"

"Say it!" Cynthia didn't want to wait a second.

"Uh......" Alan thought for a moment, then said slowly, "I was thinking...... Could the original manuscript of this book be older than the age of this bookstore?"
