After a while, Wood put the ghost mirror back in his pocket, but Wood didn't notice at this time, when he put the ghost mirror in his pocket, there seemed to be a drop of liquid in it, slowly sliding down the inner wall of the ghost mirror. On the inner wall of the whole black body, a clear scratch is left. It's just that the scratch didn't last long, and it was soon re-covered by those black smoke.

This book, Wood has read it several times in the last few days, but in addition to those whom Wood has never seen before, there is a ghost mirror with black at the end.

The images that appeared on the ghost mirror on the previous pages, Wood found that they were never repeated. Every time Wood opened it to look at it, the image that appeared on it was something Wood had never seen before. But the people above haven't changed, there will always be a few fixed faces on each mirror, but they do things differently every time.

Wood looked at these people carefully, judging from what they were doing, these people should be some soldiers, and the clothes they wore were different, and their identities should be different. Different colors of clothes represent different identities. It's just that such a soldier has never been encountered in the world in which Wood lives. Where there are soldiers, it often represents war, but neither where Wood lived before nor in the academy where he lives now, there are no soldiers. War had never befallen them, so soldiers were completely aliens to them.

Maybe it's just the scene that appears in the ghost, not what's happening, but some images that have been preserved before. It's just that Wood happened to start these, so he let Wood see it. Wood himself thinks so, because he doesn't think that in such a peaceful world, there will be war.

Before leaving, Professor Shivara told Wood that what he had taken out of the illusion would only remain with him for seven days. When the time comes, the book will automatically disappear and return to its original place. In other words, the book has to go back to that dungeon, and there are more books in that dungeon. What Wood couldn't figure out was why the books were in the dungeon, and why there were still guards there.

At that time, this question only flashed in Wood's mind, and he didn't have time to think about it, but now that he has time, and when he thinks about it, Wood feels more and more suspicious about this dungeon. The books that were kept in the dungeon were like prisoners held there, and there were guards outside.

There was a slight sound of footsteps in the library, and Wood quickly tucked the book into his palm, picked up another book, and pretended to be reading it seriously. And the man didn't walk towards the bookshelf, but straight in the direction of Wood.

"Professor Siye, are you here to read?" Wood looked up to see that it was Professor Siye, and a trace of unease crossed his face. I don't know what Professor Siye is doing here, but does Professor Siye already know something?

"Reading a book here alone, Suri aren't they with you?" Professor Theye sat across from Wood like a nobody, picked up a book from the bookshelf behind him, and found that it was nothing more than a simple magic book, and put it back in place very casually.

"They're all busy with their own business, so I'll come here to read when I'm fine. Wood didn't dare to look Professor Siye in the eye, but replied sullenly with his head down.

"Principal Brooke was very satisfied with your performance in the illusion last time, although the other students did a good job, but you showed that you were unusually brave. Professor Theye said seemingly casually, with a smile on his face that made Wood feel very uncomfortable.

"I have a question, we were in the fantasy world, we went to the ice and snow kingdom, I don't know if everything in it is real. I mean, is everything we see and know in the realm of ice and snow in the realm of illusion also real and happening?" Wood said incoherently, wondering if Professor Theye could understand what he meant.

"Of course, everything you see in the illusion is real, including the beasts. It's just that because they appeared in my illusion, their power will be weakened accordingly. At the same time, we will protect you in the shadows from any real harm. Therefore, everything that happens in the illusion is real and reliable, the only difference is that the things in the illusion only belong to the illusion. No one but me can change everything inside. Professor Seyer's explanation was not very clear to Wood.

But the answer he wanted to know, Wood already knew in his heart, that is, the dungeon they found in the illusion was real, and the books were also real.

"We used to see some faceless icemen in that dungeon, and we don't know who those were and why they were there?" Wood realized that he was asking a little abruptly. These topics already involve privacy, and perhaps Professor Siye doesn't know the answers, because he is just a fantasy based on reality. Even if Professor Siye knew, he might not tell himself. I am just a student, and I am not qualified to know anything other than studying.

"Those icemen are actually the guards of the Ice and Snow Kingdom, and the Ice and Snow Kingdom lives up to its name, there is ice everywhere there, and it can be seen everywhere. Therefore, it was almost unsuitable for human life, and later, in order to protect the people of the Ice and Snow Kingdom, the king there came up with this solution. Many soldiers are made of ice with their own magic, which is also a kind of protection for the Ice Kingdom. Professor Siye's words really surprised Wood, he had been to the Ice Kingdom, and he didn't know that there were such soldiers there, and Madame had never mentioned it to him.

Even when the Lady knew that Wood had met the soldiers, she never said a word about it to herself.

"The soldiers, in that dungeon, there's no one there, what are they not guarding?" Wood asked curiously, still unaware that his questions were becoming more and more private, and it was rare that Professor Theye patiently explained to Wood.
