In the process of the experiment just now, Ivan also noticed a hidden factor, that is, his own knowledge accumulation will also affect the efficiency and speed of learning.

This is also the reason why it only takes about 20 minutes to read a "Beginner's Guide to Transfiguration", and the time to read "Detailed Explanation of Basic Spell Principles" is much slower, and only half of it is read in 30 minutes.

The quick reading of the "Beginner's Guide to Transfiguration" is partly due to the fact that Ivan himself has some foundation for casting transfiguration spells, and on the other hand, because he has just read this book and has an understanding of the content in the book.

And "Detailed Explanation of Basic Spell Principles" involves a wide range of knowledge, and Ivan has not read it in advance, so the reading speed is relatively slow.

After analyzing the advantages and disadvantages of the Xueba experience card, Ivan immediately realized that if he wanted to make good use of this hour's time, the optimal solution was to read the corresponding book first, and then review it after reading and using the Xueba experience card to improve his comprehension and thinking ability, so as to make the most of the time.

And every time you understand a magic book thoroughly, there will be a reward for academic grade points, plus to increase the level of the spell, the accumulated academic grade points can be used to exchange for the academic experience card, so under the cycle, won't the strength improve by leaps and bounds?

Just now, Ivan had only read half of the "Detailed Explanation of the Principles of Basic Spells", and all the spells he knew had increased his proficiency a lot, among which the Levitation Charm and the Disarming Charm had been upgraded to the same level as the Transfiguration Charm, and he was rewarded with ten GPA points again.

This made Ivan's originally cleared GPA increase of 20 points again, greatly reducing the time to collect GPA points next time.

Thinking of this, Ivan looked at the vast sea of magic books in the library, and suddenly realized.... These are all grade points!

If he could read them all, it would be hard for Ivan to imagine how much his strength would grow.

Thinking of this, Ivan regained his fighting spirit.

However, it backfired, and just as Ivan was about to work hard, he was told that it was time to turn off the lights in the library.

Only then did Ivan realize that he had been in the library for more than three hours.

"Children, learning knowledge is important, but we should also pay attention to the combination of work and rest. Let's all go back to my dorm room in my respective college! Mrs. Pince chased away the young wizards who were still in the library.

As a Hogwarts librarian, she certainly doesn't hate little wizards who like knowledge, as long as she doesn't make a lot of noise in the library, but the headmaster of the library has a rule for opening hours, and Mrs. Pince can't extend it.

Ivan stepped forward at this moment, took the half-seen "Detailed Explanation of the Basic Spell Principle" in his hand, and gestured.

"Ma'am, can I borrow this book if I want?"

"Of course, as long as it can be returned within the specified time." Mrs. Pince glanced at the book, and after reading the title of the book, nodded casually.

With that, Mrs. Pince turned and searched the library. There are always a few people who like to hide themselves in the sea of books, intending to get through the tricks, and sneak into the forbidden area after the lights go out.

Of course, there are also individuals who are fascinated by seeing and forgetting the time...

"Thank you—" Ivan nodded politely in thanks, and then left the library with the book, eager to go back and try out the improved magic.

"Let Jean .. Let's go... Yikes! ”

Ivan, who hadn't walked a few steps after turning around, only had time to hear a few crisp female voices behind him, and he felt that he had been hit by someone, and his forehead made direct contact with the wall, and then he sat on the ground, and the "Detailed Explanation of the Basic Spell Principle" in his hand also fell to the ground.

Fortunately, the force of the impact was not heavy, and Ivan touched his somewhat red forehead and got up.

Ivan picked up the book first, and then noticed the little girl who had recklessly bumped into him,

The first thing that caught the eye was the thick brown hair, which was obviously uncared for by its owner, and the standard wizard's robe looked slightly wide on his body, and there were several magic books scattered around his side.

"Hermione?" Ivan was stunned, but quickly figured out the situation.

Presumably, our Miss Jack-of-all-trades was in too much of a hurry when she was kicked out of the library by Mrs. Pince, so she ran into him directly from behind.

"Ivan?" Hermione was also hit lightly all of a sudden, until she was helped by Ivan, and then she stood up. "Oh, I'm sorry, I might have been a little confused before, I didn't expect to bump into you..."

"It's okay, just pay attention next time." Ivan picked up the book on the floor and handed it back to Hermione, shaking his head to show that he didn't care.

Hermione, however, immediately opened the conversation after seeing the book in Ivan's hand, and said endlessly.

"I've borrowed this book before, and I've learned a lot of new magic skills.

Oh my God, I didn't know that a strong will could make some spells more powerful, but it requires the wizard to have a high level of magical control, otherwise, there is a good chance that the magic will get out of control..."

At this, Hermione said as if she remembered something, and her voice became high. "By the way, learning requires understanding and memorization, not reading a book from beginning to end.

Rather than reading a book like "A Detailed Explanation of Basic Spell Principles", I think you should memorize all the textbooks first! ”

Hermione confided her thoughts or experiences like a barrage, perhaps consciously helping Ivan, and there was always a bit of a sense of superiority.

Ivan understood that Hermione must have seen the scene of learning with the help of the Xueba experience card in the second half of the year, so he kindly reminded hermone, but Hermione's arrogant tone still made Ivan frown slightly.

"Thanks for the reminder, but I think everyone has their own way of learning." Ivan said lightly, only then did he understand why Harry, Ron, and the other little wizards didn't want to see the clever Hermione.

I have to say that before Halloween, Miss Granger's personality was indeed not very likable...

"How is that possible?"

Hermione was still thinking about continuing to preach, but as soon as she spoke, she was interrupted by Ivan's actions.

"Rapid transformation~" Ivan waved his wand and tapped on the parchment that Hermione used to take notes, the paper vibrated slightly, and then swelled and deformed, and the slightly rough parchment slowly became smooth and flawless.

Right in front of Hermione, in a second or two, Ivan went from pronouncing the spell to waving his wand, just like Professor McGonagall had demonstrated, and the parchment had now turned into a thin jade slab.
