After an unknown amount of time, Kewen slowly opened his closed eyes.

"How? Did it succeed?" Ollivander asked eagerly when he saw this.

"Uh..." Kewen scratched his head.

Ollivander saw this, his heart sank, and he asked in surprise, "Failed?"

"No, how do you say it..." Kewen's tone was a little tangled: "Success is success, but what I built in the end was not a library."

"Not the library?" Ollivander frowned slightly, "Are you sure you succeeded?"

"I can be sure of this." Kewen nodded firmly: "The things I built are like... like a few boxes."

Kewen made a metaphor and used his gestures to cooperate: "It's not like the library where all the memories are in one room, but the memories are divided into several boxes, and there are more small boxes in the box, I built it like this. "

Ollivander fantasized following Cowen's description, and said uncertainly for a while, "In this way, I'm not sure which effect you have constructed like this is suitable for the effect of the library I mentioned."

"This is more unexpected..." Kewen scratched his head a little embarrassedly: "When I first started building, I couldn't help but build it like that. I couldn't help it. When I recovered, it was too late to change it back."

"Can't help it?" Ollivander was slightly stunned, and after thinking about it, the worry on his face disappeared, but instead said happily: "As long as you can be sure of success, involuntarily... I think this may be fate for you. After all, everyone has different effects of casting spells, I guess, it may be that your wizard intuition helped you make this choice, and this choice may be the most suitable for you."

"Maybe..." Kewen's tone was a little uncertain, but he couldn't explain the truth. After all, if he did, Ollivander wouldn't understand what a computer was.

What's more, if Kewen explained it truthfully, I am afraid that due to various unreasonable details, his identity as a "traverser" would be exposed again.

He managed to maintain the character design, so that Ollivander and the academy ignored all kinds of unreasonable things in him, so that no one went to investigate his details...

This concludes the topic of the success of the 'Memory Spell'.

Ollivander asked another topic: "Okay, you will experience the effect yourself in the future. Do you still have energy now?"

"I'm fine." Cowen affirmed.

"In that case, then let's continue to learn Occlumency." Ollivander suggested.

"Okay sir, how do we start?" Kewen said, but his heart was suddenly stunned.

Because when Ollivander uttered the word 'Occlumency', all his memories of 'Occlumency' suddenly appeared in Kewen's mind.

All the information and pictures that he had obtained by consulting the data on the computer at the beginning suddenly appeared clearly in his mind, as if he was there.

As a result, Kewen couldn't help being stunned. The effect of this 'memory spell' was amazing!

"What's wrong with you?" Ollivander asked curiously when he saw Kewen's dazed expression.

"Ah? Oh it's nothing." Kewen returned to his senses and explained: "I remembered why the word 'Occlumency' was familiar to me. I saw it in a book when I was looking for materials in the library. over the word."

"I see." Ollivander believed Kewen's improvised lie, and said happily, "It seems that your 'memory spell' succeeded, congratulations."

"Thank you sir." Kewen thanked, and at the same time quickly changed the subject: "Let's start studying, what do I need to do this time?"

"occulto mens, this is a spell." Ollivander said, "you read it with me first, oh, I forgot, now you only need to remember what you want to remember, you can remember it by listening or watching it once."

Kewen couldn't help laughing when he heard the words: "Yes sir, I think I have memorized the spell."

"Okay." Ollivander laughed and shook his head, and then warned, "But this spell has higher requirements."

"What's the request?" Kewen murmured.

"Because 'Occlumency' is used for secrecy, it can't be obvious when it is required to be used, otherwise others will know that you are going to lie and hide your memory."

Ollivander explained: "Therefore, the spell is used silently and without a wand."

"I can do it silently." Ke Wen nodded and asked curiously, "But how can I do it without a stick?"

"Strong thoughts!" Ollivander taught in a deep voice.

"Strong thoughts?" Kewen said as a repeater.

"Yes, strong thoughts." Ollivander repeated solemnly again, and then explained: "Most magic spells without sticks are like this, you need extremely strong thoughts, and you need to be very clear about the spell. Effect."

"This is similar to the 'silent spellcasting technique' that I summarized." Cowen said, explaining to Ollivander the "silent spellcasting technique" he had summarized.

"You're a genius." Ollivander sighed after hearing it, and continued: "You summed it up perfectly, and the 'stickless spellcasting' technique is like I said, but few people can do both."

"What do you mean..." Kewen said, "Most people can only cast spells without a voice, or cast spells without a stick. Can't they use both techniques at the same time?"

"Yes." Ollivander nodded affirmatively: "Most wizards are like this. Because if you want to use the two together, it requires years of practice and superb talent."

"Most people can only use a few of their commonly used spells to do both. Only a wizard like your principal Dumbledore can use both techniques to release most of the spells."

"I see." Kewen responded suddenly.

"Okay, let's start practicing." Ollivander pointed out: "First of all, you need to recall the contents of the 'Wand Materials Science' book just now in your mind, and then I will apply 'Intake Spiritual Mind' to you, You have to try and resist me reading your thoughts."

Kewen felt relieved when he heard the words, glad that the memory Ollivander chose to read was so safe.

Taking a deep breath and getting ready, Cowen then nodded to Ollivander to signal that he was ready, recalling the contents of the book.

Seeing this, Ollivander pointed to Kewen with his wand, chanted the incantation 'Inspiration', and began to read the thoughts in Kewen's mind.

The next moment, an extremely strong sense of peep was captured by Kewen's sixth sense of martial artist.

To use a metaphor, it's as if someone wants to strip him naked, which makes people feel extremely uncomfortable...
