The content of this "Principle" book can be described as very superficial for Xia Duo now, but after reading it, there are still some inspirations in his mind, and he captures them one by one.

As the saying goes, "read a book a hundred times and see its own meaning", even if this book has been defined by him as "a magic popularization textbook suitable for beginners", it can still have an effect on Xia Duo.

So, Xia Duo opened "Principle" again, and this time it was slower than the last time, and the second time he finished it, he also gained something.

Moreover, after comparing the direct retrospective memory in his mind with the real life of looking through specific books, Xia Duo found that inspiration is not related to speed, but to time.

This is also in line with his most simple perception of thinking, the same content, the longer you think, the more inspiration you will have.

Retrospective memory improves his memory, not his speed of thinking.

The speed of thinking itself is extremely fast, but it is also greatly affected by memory, and the improvement of memory can also play a positive role in thinking.

After all, there is no need to waste time recalling, and there is no need to think about the possibility of breaking the file occasionally.

Chador's heart was overjoyed, and after talking to Layton, he returned to the Tower of Time.

Just now, he was just trying to prepare for writing a book, but he didn't expect the effect of memory tracing ability to be so good, and he wrote it directly.

But now that he knew that his ability was so strong, Xia Duo felt that he could do better, after all, he hadn't finished reading all the books in the Tower of Time Library!

……

Xia Duo's two visits and returns aroused Nia's curiosity, she knew that Xia Duo had gone to the Great Xia Collar before, but she didn't know what was going on later.

Asking Taling to find out that Xodor was now in the library, Nia immediately chose to teleport.

The tower master has no taboos, so he can naturally teleport at will, even in the library, and her arrival has also attracted the attention of Xia Duo.

Just as he finished flipping through a book and wanted to put it back on the shelf, the [Delayed Teleportation] that was resident on Xia Duo's body suddenly detected a nearby teleportation signal.

Xia Duo was shocked at first, but then realized that he was in the Tower of Time Library, and the only person who could teleport here was Nia.

With a move of will, he stopped the automatic reaction of the spell, and did not choose to delay Nia's teleportation, and then the teleportation fluctuations suddenly became violent, and with a flash of white light, a pretty figure appeared next to the bookshelf.

"Xia Duo, didn't you go back to the territory?"

"Well, after the matter over there is settled, it's back again!" Xia Duo took the new book from the shelf and quickly flipped through it as he talked to Nia.

And Niya, watching Xia Duo's continuous flipping through the book, the curiosity in her eyes became even heavier, "Are you looking for any information?" It would be very convenient to ask Taling to do a preliminary screening first, and then look for it. ”

Xia Duo paused his hand, thought for a moment, closed the book and turned to look at Nia, "I'm not looking for any information, I'm reading a book." The last time the bloodline awakened, only now did I realize that my memory had also been improved, just read more books, in case I can use it one day! ”

"You turn so fast, can you really remember it?" There was something strange in Nia's eyes.

"Of course you can!" Xia Duo said confidently, "I don't believe you to ask questions, see if I can remember." ”

As he spoke, he handed the book in his hand towards Nia.

However, Niya did not answer, but said directly: "I believe you." ”

In this way, Xia Duo continued to turn the book, and Niya looked at it, her expression gradually changed, and after Xia Duo finished turning the two books again, she couldn't help but say:

"The teacher knows a fast reading spell, and she told me to teach me when I pass her test!"

“……”

Xia Duo glanced back at Nya and immediately smiled, Nya now looks very much like when he saw other children buy new toys when he was a child-

envious, but pretending not to care, and specially emphasized that I would buy it for me at home!

"What are you laughing at? Don't you trust the teacher? ”

"No, I didn't."

In fact, when Shado heard Nia say that the princess had a spell for speed reading, he immediately remembered the first time he saw the princess-

After he handed the "Great Xia Collar Standard Development Manual" to the princess, the princess cast a spell on it, and then knew the contents of it.

This efficiency is even faster than he can turn the pages of a book.

He had envied it in the past, but since he had the ability to trace his memory, he didn't envy it at all.

Because his ability is passive, it may consume energy, but it is definitely less than casting spells, at least he has now turned over more than ten books, and he hardly feels tired.

And in the past few days after changing the state of his soul and gaining the ability to trace his memory, he has never felt tired from remembering and thinking.

It all came naturally, as if he had been born with a similar ability to remember.

That's a lot better than a speed-reading spell.

After comforting Nia away, Xia Duo sped up the speed of flipping through the book again, and as he flipped it, he still had a vision.

It would be great if you could combine that kind of quick reading spell with his memory tracing ability, touch it, and remember it all, and at the same time it doesn't cost much energy!

……

In the continuous flipping of books, more than ten hours passed quickly, and the time came to the next morning.

Xia Duo put the last book on the shelf, then stretched comfortably, and after a night of sleep, he finally finished reading all the books in the library.

From today onwards, he can be called a "mobile library".

It's a pity that the collection of books in the Tower of Time is still a bit small, and he has decided to go to Severynton after a while, in addition to promoting new books and communication tools, and more importantly, it is-

Take a trip to the Gillesgaard Tower and the library of the Austrian Federation.

Although he doesn't have access to some books or has to pay for them, he believes that it will definitely be a big reward!

……

Back at the residence, considering that he had been busy all night before, Xia Duo gave himself a [deep sleep], and he woke up leisurely near noon.

After waking up, he moved his body a little, and while nibbling on steamed buns with fruit wine, he went out and walked towards the elevator.

At the same time, in Xia Duo's mind, countless words and images flashed rapidly, and he was constantly recalling the results of last night's all-nighter, thinking about and integrating them.

By the time he arrived at the public floor, in just a few minutes, Xia Duo had a more comprehensive understanding of the Tower of Time Library, and had some new ideas on how to revise and improve the Principles next.

……

Registrar's Office.

José looked at the six instructors in a row in front of his desk with a blank face, and cried out in his heart, only a few days after the new system for the spell practice room was introduced, someone wanted to reduce the number of people in the class.

What they were thinking, how could Jose not know, it was nothing more than that they felt that there was only one practice session left, and that they had less time to control themselves, so they were not satisfied and tried to change something.

"What the hell are you trying to do? Isn't the Tower of Time too good for you? ”

"Master José, we all feel that we are not capable enough to take care of all the existing students in the class and reduce the number of students, which is a very reasonable request."
