Seeing Ollivander admit that the reason he was able to remember every wand and its owner was because of the effect of the 'Memory Charm', Cowen couldn't help being a little overexcited.

"You said that Mrs. Pings in the college library would also..." Kewen thought of something at this time, and said suddenly: "No wonder! No wonder Mrs. Pings can easily point out the locations of all books! It is because she also Advanced usage of 'Memory Spell'!"

"Well, that's right." Ollivander looked at Kewen's excited expression, nodded amusedly, and said, "Three generations up, my family is close relatives of Mrs. Pace's family, so their family's family , and now also masters the advanced usage of 'memory spell'."

"Sir, I can't wait!" After Kewen heard the words, he looked at the potion in Ollivander's hand with light, and asked eagerly, "How do you use this potion? Drink it directly?"

"That's right." Ollivander nodded and said with a smile: "The configuration of this potion is no less difficult than the 'Fu Lingji'. Before you drink this potion, you must keep a few steps in mind."

"Sir, please speak!" Kewen's expression became focused and serious.

Ollivander was very satisfied with Kewen's seriousness. He was really afraid that Kewen had been so impatient all the time, which would be detrimental to the study of the "Memory Spell", and there was a high chance of wasting potions.

Seeing that Kewen had calmed down, Ollivander began to exhort dignifiedly: "First of all, child, you need to master the standard spell of 'Memory Spell'. Once you master the spell proficiently and correctly, you can drink the potion, right? I cast the 'Memory Charm' myself."

"I remember!" Kewen nodded heavily.

"I haven't finished speaking yet." Ollivander laughed and continued: "The first time you finish drinking the potion, you have to think about it in your mind, and use your consciousness to make up a place to store your memories in your mind. Basically, It's a library, because a library is the best fit."

"So the effect of this potion is to immobilize the 'library' conceived by your consciousness. This is the most important step!"

"Conception..." Kewen pondered, then looked at Ollivander and said deliberately: "I think I have no problem, I can imitate a Hogwarts library."

"Very good." Ollivander nodded with satisfaction, and continued: "After the virtual library is fixed in consciousness, you have to divide the library step by step. My suggestion is to divide life, common sense, and knowledge. After the memories are sorted, they can be grouped into different sections of the library.”

"Well, I remember it!" Kewen confirmed again seriously.

"I believe in you." Ollivander encouraged with a smile: "After all, I haven't seen a child smarter than you."

Kewen smiled modestly, but asked with some concern: "Then, sir, I mean, what if it fails?"

Ollivander laughed when he heard the words, and then comforted: "Don't worry, other than wasting this precious potion, there will be no hidden dangers."

"That's fine." Kewen was relieved.

"No, that's not good." Ollivander kept a smile and shook his head: "Son, this bottle of potion is not easy to configure, after all, the formula of this potion is also confidential, and I have no knowledge in the configuration of potions. So if you want me to make another bottle of potion, I’m afraid I don’t know how long it will take, and I don’t know how much gold Galleon will be wasted.”

"Huh?" Kewen was a little dumbfounded.

"So kid, you have to be serious." Ollivander urged jokingly.

"Well, I will!" Kewen replied solemnly.

"Come on, let's learn the 'Memory Spell' first, and I'll teach you the correct way to read the spell." Ollivander put the potion aside first, and then said to Cowen.

Kewen responded and raised his spirit.

Next, Kewen followed Ollivander to recite the spell of 'Memory Spell' over and over again,

Even after making sure he could read correctly, Kewen continued to read for a while.

After confirming that he could not read it wrong, Kewen continued to the next step and began to experiment with the common usage of 'Memory Charm', took a book on wand materials handed by Ollivander, and started to use 'Memory Charm' to try to use it. memory.

The test results were successful.

The content of the entire book, Kewen only read it roughly, and did not deliberately recite it.

But under the effect of the 'memory spell', after Kewen closed the book, he still clearly remembered the contents of the entire book.

Ollivander took a page and asked questions, and Kewen answered all of them correctly.

So far, the common usage of the 'memory spell' has been completely mastered by Kewen, and the next important moment is.

After taking a few deep breaths, Kewen calmed down, and under Ollivander's attention, he pulled the cork off the bottle and drank the potion with his head up.

"Okay! Now use your thoughts to build a virtual library in your mind!" Ollivander reminded nervously.

Kewen nodded slightly with a serious look, then closed his eyes and concentrated more.

But at the beginning of building the library in his mind, Kewen couldn't help but slip away for a moment.

Because he thought of the computer, and wondered if he could build a 'virtual computer'.

With this thought, I couldn't help but get out of hand.

Yes, if you compare memory to data, then the computer can also perfectly separate and store it. Whether it is dividing disks or creating folders, isn’t it more convenient and meticulous than libraries?

And the computer can also be used as a calculator.

Kewen diverged his thinking: I happen to know a lot of algorithm formulas, etc. If I build a computer, can I use it to calculate more easily?

There are also magic spells that you have mastered. You can compare them to small programs. Then the computer can also run these programs with one key. If you change it to the body, can you successfully release the magic spell with a single thought?

The more he thought about it, the more Kewen felt that building a computer was more perfect than building a library.

Because the thoughts were too concentrated, the corner of the library structure that Kewen had originally created in his mind disappeared without knowing it, and instead the image of the computer operation interface appeared.

By the time Kewen reacted, he had almost made up the picture of the hard disk partition in his mind.

My mind was excited, my thoughts were clear.

But there was no time to correct it, because he felt that the efficacy of the medicine in his body was rapidly disappearing.

As a result, Kewen could only grit his teeth and not change at all, just use the computer mode.

However, the time for the effect of the medicine is short, and Kewen has no time to add any 'calculator' programs in detail, so he can only construct the partition of the hard disk first. We can only talk about it slowly in the future.

If it's a big deal, if he can't build it perfectly this time, he will study the potion configuration carefully in the future, configure the potion by himself, and then apply an upgrade patch...
