Su Wen consulted a variety of books in the old hall, and sometimes even flipped to one casually and began to read, if it wasn't the kind of book that had nothing to say, he could basically read it from beginning to end.

In terms of reading speed, Su Wen did not have some bonuses obtained through his own ability, and his speed was maintained at a speed that was relatively faster than that of ordinary people. But the ability to absorb information is beyond the reach of others.

Among these ancient books, Su Wen's favorite thing to read is still those biographies or miscellaneous stories that record history, compared with the official history books released by the Marenor Empire, these books also bring the stories that happened at that time to readers from another aspect and another perspective.

The reversals of some stories and hidden dark lines also made Su Wen extremely interesting.

For example, the real reason why a northern country attacked the Maleno Empire hundreds of years ago was not to covet the fertile land of Maleno. Rather, their commander led his men to hunt and accidentally crossed the border. After being warned by the guards of the Marenor Empire, he couldn't lose this face, so he just led the troops to attack.

Although it sounds a bit child's play, Su Wen feels that it is actually a little credible.

Because even in the official history of Makeno, the account of this event is vague. The other works of the author of that book are all rigorous and detailed, and there is no reason to deceive and falsify this book.

And so on and so forth.

Su Wen sometimes even found some sense of déjà vu in some books. But just like a dream, for Su Wen, it was just an illusory and untouchable illusion.

But Su Wen also knew that it might be something he had really experienced.

But without the support of memory, everything is still equal to zero.

However, this is not something that Su Wen needs to worry about, for him, these things are almost dispensable. Because now he actually has nothing to do, and Su Wen doesn't have much motivation to do it, so it's better to stay in the academy and watch Ellie grow up to be interesting.

Of course, it's just as interesting to look at the ancient books in the library.

"Monster traces?"

At a glance, Su Wen found a shabby ancient book whose name interested him quite a lot. Although the cover of the book is in tatters, it can barely remain intact thanks to the maintenance magic of the book. It also looks like an old book.

This magic that maintains the integrity of the book only needs to be cast once, and it can be maintained forever. Because the bookshelves in the old library are made by a special process, and there are magic patterns on them, which can continuously provide energy for the magic on these books.

Even if it is away from the shelf for a long time, the magic will also decay. But that's why the position of librarian exists.

In other words, the librarians of the old hall are also excellent magicians who are not low in magic.

Su Wen gently opened the cover of "Monster Origins", and on the title page, the names of several people were scribbled. Presumably the signatures of previous owners who once owned the book, and in the center of the title page, there is a magic seal belonging to the library of the Imperial College of Marenor, declaring the current ownership of the book.

Turning to the next page, Su Wen saw a huge illustration spanning two pages. On this illustration, delicate brushstrokes depict a scene of "a hundred demons gathering" in detail. Su Wen roughly counted the types of monsters on it, even if there were not a hundred, at least seventy or eighty.

At the top of the illustration, they are arranged from left to right in order of strength. From the weakest imps to high-level demons, they all vividly show their bodies on the illustrations.

Su Wen also noticed that the giant dragon was also in this illustration, and it was soaring in the sky, majestic!

There are also five kinds of humanoid monsters, in addition to the succubi and blood species that Su Wen already knows from other places, there are three kinds of existences that Su Wen does not know.

It is worth mentioning that even the monster of the cave worm also shows its face on it, and in this area, there are three cave worms in different forms at the same time.

In addition to the form on the Tower of Oblivion, there is also the form of a cocoon and the form of an adult. The cocoon is nothing special, but the adult in the illustration is closer to the appearance of a humanoid monster.

Judging from the arrangement of the monsters, the grade of this cave worm is not low.

Interesting!

Su Wen was a little impatient and began to flip through the rest of the content.

Yumi at the counter, in the interval between packing up the books, saw standing in front of the bookshelf, flipping through a book with relish, and didn't move for a long time.

Based on his observation of Su Wen for such a long time, Yumi knew that this young teacher should have discovered some interesting books.

According to Su Wen's usual habit, he should have taken one or two books, sat on a chair next to him, and read them carefully.

Even Yumi couldn't read all the books in the entire old building. In fact, Yumi has only read nearly 100 books for such a long time, not even one percent.

So she naturally became interested in the book in Su Wen's hand.

Su Wen stood in front of the bookshelf for about an hour before closing the book and looking at its cover with great interest.

Although this book is very well illillated, wherever there is text, its content is extremely detailed and concise, without a bit of nonsense.

In today's terms, the content in this book is all real dry goods, and there is no irrigation in it. This makes most authors, including my rice Li Yitong, ashamed of themselves and eager to find a hole to get into.

In addition to the introduction of some monsters, this book also depicts several ancient magic arrays, but most of them are also incomplete and have no practical effect.

In general, Su Wen can be regarded as having gained a lot.

After reading this book, Su Wen said goodbye to Yumi and left the library, the finishing work of the second training ground had been put on the daily schedule, and he was going to do the final repairs.

Yumi was stunned for a while, and then, driven by curiosity, came to the bookshelf where Su Wen was standing not long ago, and found the book "Tracing the Origin of Monsters".

Then, stepping on a stool, she took out the quaint book that had been placed on a high elevation.

Like Su Wen, Yumi is also in front of the bookshelf, so immersed in the world depicted in the book that he even forgets the time for lunch.

Time passed minute by minute, and the noon sun also passed over the head of the old building and came to the other side of the window. Through the extremely artistic window frames, sunlight and shadow sprinkled throughout the old building, and also sprinkled on Yumi's face, illuminating half of her attentive face.

Yumi flipped to the last few pages—the pages where the ancient, ruined magic circle was recorded.

"Magic Array?" Yumi was a little curious, but with her attainments, she didn't seem to see why. However, she still stopped flipping through the book and carefully observed every detail of the magic array.

Perhaps because the light was not bright enough, Yumi gently tilted the book and borrowed a little sunlight from the window.

The shadows of the sun and the window frame were sprinkled on the top of the book, and likewise, on the top of the magic array.

In a trance, Yumi felt that the shape of this shadow was a little strange.

It's like ...... This strange shadow pattern seems to be an incomplete part of the magic array......

Yumi's heart beat a little, he took a few deep breaths, and then tilted the book in the direction of the window, and tilted it again, allowing the light and shadow to be projected in the entire magic array.

It's true...... Kind of!

Yumi was a little excited, and hurriedly got down from the chair, adjusting the distance and angle, trying to make this magic array complete.

At this time, curiosity and enthusiasm have thrown her reason and caution out of the clouds. The advice I received in class and at work was forgotten at this time.

With Yumi's breathing, the entire magic array was really completed!!

It's done!

Yumi's mood became more and more nervous.

But in the next moment, a strong wave of magic power rose from the magic array, and in an instant, it enveloped Yumi inside.

In just a few seconds, this sudden strange magic power dissipated in a hurry.

And Yumi's expression is a little different......
