An unused classroom, with the facilities in it removed, is common in Hogwarts.

A sword stood silently in the center.

The surface of the sword body is dull, and some people believe that it comes out of the soil.

However, this is the limit of what Roy can achieve at the moment, the limit of existence.

This sword is integrated with all his means, sword paths, spells, formations, runes...... Wait a minute.

His thoughts, his spells flowed through it.

But it's still not enough, the sword hasn't existed long enough. The sea is rotten, and with the passage of time, the sword will disappear with it.

If you just want to keep it, it's more pragmatic to choose to carve words on the stone than that.

This is still the case with things, let alone people?

But Roy didn't care.

So much had been said earlier, but he really didn't care. In his attitude, the previous introduction was like writing some meaningless nonsense on a blank piece of paper.

He really didn't care, because he didn't forge this sword to challenge time quixoteally. He's prepared for what's next.

The three of them arrived in the classroom as promised.

"You're here." Roy turned.

"Roy, that's?" Hermione's eyes sharpened, and she saw the sword behind Roy.

"Here's what I'm going to use next, you guys lean over there."

The three of them leaned over obediently.

"Now you touch it, don't be careful of cutting your hands."

The three of them were a little strange, but they tried it anyway.

When Hermione touched the sword, she felt as if the world had changed.

The air seemed to be filled with an ethereal, faint, purple mist.

"It's mana." Roy walked over and introduced.

"The mana that Hogwarts teachers and students disperse in their daily lives will be collected by the school castle to maintain the school castle."

"What I am doing now is to make the mana manifest in front of you, so that you can contact and recognize the mana."

Hermione opened her mouth to say something, but Roy interrupted her, "Don't ask me how I did it, it's not magic, I explained it and you don't understand." You'd better wait until you get up to the next level, it's not what you should understand now. ”

Hearing this, Hermione had no choice but to give up. She turned to something else: "What are you going to do next?" ”

This was also the curiosity of the other two, and they pricked up their ears to listen, lest they miss a word.

"Well, I'd better draw you a pie before that." Roy muttered as he stood across from the trio.

"Huh?" Hermione was a little puzzled, and the next moment, she felt a flower in front of her, and the classroom seemed to be stretched infinitely, with a deep and boundless starry sky in all directions, and they seemed to be in the universe.

The top, bottom, left and right are all dark, and the abyss that cannot be seen to the end is dotted with fluorescent glows.

Roy was very interested, carefully observing the expressions of the three people, and the faces of the three of them invariably showed a look: the kind of expression that people should have in the starry sky of the universe.

"What do you want to see here? Or will you feel more at ease when you are down-to-earth? Looking at the expressions on the faces of the three people, Roy was happy.

The stars of the universe evolved according to his will, and the starry sky faded, replaced by a barren and empty loess land. The darkness overhead turned into a sky, a monotonous and dull sky, not even a cloud could be seen, as dry as the land.

It all receded like a tide, everything was gone, and they were back in the abandoned classroom.

"That was ...... just now" After a while, someone spoke slowly, as if he had not yet recovered from the scene just now.

"Was that real?" Roy helped the man fill in what she had to say, "There is, but it doesn't exist." It's still the same as before, and I'll explain it later. ”

Hermione was a little aggrieved, why every time she asked, she would talk about it next time.

After the other two came to their senses, Roy said: "The previous world seemed to be real but not real, it seemed to be virtual and not virtual, and it was between virtual and real. However, I wonder if Transfiguration can achieve something like this. ”

The idea was not groundless, but came from a recent discovery by Roy.

A wizard's mana comes from the mind, and his spiritual power comes from the spirit.

Immortal cultivators will open up a secret realm of divine consciousness, and this secret realm of divine consciousness is the prototype of a world.

His Divine Consciousness Secret Realm is placed in the spiritual space, so if the wizard also has a world prototype similar to the Divine Consciousness Secret Realm, where should it be placed? Is it placed in the heart?

Among the wizards' magic, Transfiguration is the science that has the most relevance to this, and Roy's idea is to first use the Immortal Dao Spell to open up a portable space in reality, and then use Transfiguration to transform it.

The reason why the Transfiguration Technique is used here instead of the Immortal Dao Spell to transform the carry-on space is for the preparation later.

After Transfiguration transforms the carry-on space, a preliminary foundation is completed. Although the personal space here is inseparable from the wizard, and even when facing enemies in the wild, you can incorporate the other party into the space and use the space to assist yourself, but it is still an external object, not one with yourself.

And incorporating this portable space into your own mind is the ultimate goal. The portable space is incorporated into the mind, integrated with the mind, and completely becomes its own world. The previous use of wizard spells to transform the space is also to brand the space with its own imprint. The foundation was laid for a framework opened up by immortal arts, and the interior transformed by magic was branded.

It is only after this step that the portable space has infinite possibilities, no, it can no longer be called a portable space at that time, but the prototype of the world.

The prototype of the world of immortal cultivators is called the Divine Consciousness Secret Realm, also known as the Immortal Realm, and the wizard's is called the Kingdom of God.

It's a bit too much, it's hard for these little cubs in front of me to even change a needle, let alone a more advanced transformation technique.

But that's why Roy called them here, if according to the level of education at Hogwarts, after these two graduates, only Hermione can barely renovate a qualified space.

And the magic of these guys is still in the upper reaches of the whole of Hogwarts, which is terrifying, brother.

If this is true upstream, what about the others? Thinking that when it was promoted to the wizarding world in the future, all the wizards he encountered were of this level or even inferior to this level, and Roy's heart was gloomy.

Therefore, it is imperative to increase the per capita education level of wizards. At present, these three people are the first "guinea pigs" to receive education.

……

As we all know, learning things has to be gradual, starting from the basics, so the first thing they have to learn is to control the mana in their bodies, and the level must at least reach the level of being able to cast ordinary spells without a wand and silently to be considered passable.

"I already have a rough idea in mind to use Transfiguration to achieve the effect just now, but to really achieve ......."

"That...... I have a question. Hermione cautiously interrupted Roy.

"Huh? Do you want to ask why you're doing this, and not anyone else or myself? Roy looked at her.

"Yes."

"Ah......h

He paused for a moment and said an answer that surprised the three of them: "I don't have any requirements for candidates, as long as you are able-bodied humans, the reason why I chose you is purely because I just want to choose you." ”

"Huh? It's as simple as that? Ron exclaimed.

"Or else? You don't think you're the chosen one to save the world, do you? Roy gave him a strange look, "Although it is normal for you to have this idea at your age, I still advise you not to be imaginative all day long, and study magic hard, so that you can use magic to achieve it." ”

“……”×3

It seems that this guy's magic level is directly proportional to his aggressiveness.

"Okay, okay, time is pressing, let's practice mana control at noon today."

"Whoever of you can spell, no matter the level, just one. Raise your hand. ”

"Me." Hermione raised her hand.

And the other two...... You look at me, I look at you, look at each other.

“…… I'm not surprised by this result...... Looks like we'll have to start from scratch......" Roy felt the urge to twitch the corners of his mouth, and if it wasn't for the fact that it was too vulgar, he would have done it.

"Levitation Charm...... How is it again...... But the basics are the basics. Roy pulled the book out of the void and searched through his inventory.

"Fluorescent Flickering Spell...... It's okay, this mastery can be used as a flashbang to give the enemy a cold shot during a fight. And it can also improve the lighting environment, I almost didn't blind my eyes when I watched the movie......"

Harry and the others just watched as Roy flipped through the book and muttered words in his mouth.

"Arvada...... Forget that, unless I want to play the Hogwarts speedrun......"

In other words, does the Avada Destiny Spell not need to build nodes? Roy stopped and noticed a problem.

In the original book, Voldemort's posture of Arvada seems to be quite casual? But that guy shouts quite loudly when he uses it, not to build auxiliary nodes but for emotional bonuses?

There are too few cases in the original book and they are not described in detail, and I don't know how to learn them if I have no place to learn. Go back and compare a few Death Eaters and Voldemort together.

"Let's fluorescent flicker." After a long time of choosing, Roy chose to let Harry learn how to make flashbangs and faces.

After all, mage, illumination can be said to be a must-learn. But there's no need to take the big sword.

"I have a spell here, called fluorescent flicker, do you want to learn it?" Roy put down the book and asked them.

The three of them naturally agreed, and there was no way if they didn't agree, Roy still had an ebony wand in his hand.

"First of all, you have to feel the mana in your body. Close your eyes, I'll only help you once, and you'll have to rely on yourself in the future. ”

Roy snapped his fingers, and three beams of light emerged from the sword, connecting the three of them.

Harry closed his eyes and sank into space. The space is covered with mirrors that are connected together, large and small, with regular shapes, and various images reflected on them.

Harry looked up and saw that it was full of memories of his past, and just as he was about to lean over to take a look, his feet were empty and he fell.

When he woke up again, he found himself standing in front of a lake that was so transparent that it was easy to see the bottom.

"This is where your mana is." Roy walked up to him and said.

"I still close my eyes and quietly feel everything around me. This is you, and it should be easy to know what you're doing. ”

Harry obediently closed his eyes, but he was surprised to find that what he saw when he closed them was still the same scene.

He opened his eyes and told Roy what he had seen.

"Well, it's okay." Roy nodded.

"Roy, did you have to go through this step in the first place?" Harry asked curiously.

"Me? I was able to control it perfectly as soon as I felt it. ”

"......" Harry once again felt the difference between people.

……

Next to the mana pool of the other two, a similar scene was staged.

Hermione closed her eyes and had a clear view of the lake for a while, while Ron had a rough outline, a blurry vision after a while, and a clear view of the lake after a while.

"Well...... Harry was the fastest, Hermione was second, and Ron was bottom. Is this how the mental power talents of these three people are ordered? Roy sat on a mat, looking at a screen and holding a notebook to memorize.

The "Roy" who stayed by the three of them was evolved from the sword, and the real Roy rubbed the screen to watch the show in the outside world.

"But this result is not surprising, after all, Harry's original book is a typical example of the inverse ratio between theory and practice, and few people learn the Patronus Charm in the third year, but the theoretical knowledge is very difficult to learn."

"Hermione is also normal, after all, her academic hegemony is completely based on hard work, and this kind of tenacious perseverance is the embodiment of mental strength."

Ron...... There's still room for improvement, so I hope I can grow up......"

Roy commented on the trio outside, one by one.

Returning to the Lake of Mana, Roy was still teaching them.

"Let the lake move." Roy said.

Harry turned his head to look at him.

"Mentally make the lake change you want, like forming a column of water or something." Roy explained.

"Look, it's like this." Roy swiped in the air, and a screen appeared, and on the screen was a vast ocean.

There is no wind on the surface of the lake, and there are slight ripples. A black figure stood in front of the lake. Suddenly, the surface of the water moved, and one after another thick columns of water were erected, leaping into the air, transforming into dragons, phoenixes, phoenixes, and other strange beasts, and so on. The sky was obscured by the figure of the behemoth.

Harry looked at the screen, his pupils vibrating slightly.

The screen shrank to disappear, and Roy continued, "At this point, you can perfectly grasp the mana in your body. ”

Harry's heart was shocked, but he still had a question, "Why is that lake of mana so big?" Take any column of water and you'll be on the verge of catching up with my mana lake. ”

"Oh, because the CG animation mana lake just now is modeled after my own mana lake, although it's exaggerated." Roy explained indifferently.

Harry: "......"

What kind of people this is.

"Okay, let's start practicing from now on, just do what I just said, make the lake the way you want it to be in your heart, don't care if you can do it or not, you have to have the idea of 'I can do it'." Roy commanded.

Harry began to practice, and after a while, Roy shouted to stop. By this time, Harry was able to make a few small fountains appear on the surface of the lake.

"Harry, do you remember what you were going to do?" Roy looked at him with a smile on his face.

"Huh? What to do? Harry looked at him quizzically.

"That's it, that's it." The smile on Roy's face grew.

"Huh? What is it? Harry frowned.

"We have a Transfiguration class in the afternoon."

“……”

……

Roy smiled all the way through the classroom and looked at the three people in front of him in a panic.

"I think you might be able to slow down."

"But it's almost class." Hermione shouted in a panic.

"Who told you that you were going to class, and it's still far from class." Roy took out a clock and showed them the time on it.

"Huh? You didn't mean ......" Ron paused and asked Roy with a frozen expression.

"I'm just reminding you that there are classes in the afternoon, but I didn't say that there are classes now. It is you who will withdraw from it. ”

Harry, Hermione, and Ron were all a little helpless, where did they know that if they wanted to quit, they would really quit.

"The Mana Lake is your spiritual space, so it's naturally up to you." Roy shrugged, indicating that it was none of his business.

"Now that you close your eyes, you should be able to sense the mana in your body and the space where the mana lake is located. Try? ”

The three of them did so, and sure enough, they could sense it.

"I could see a space in the dark, the Lake of Mana, and I felt like if I wanted to go in, I could get in." Harry said.

The other two nodded approvingly.

"Okay, that's all for today, we'll talk about the rest later, now you better go back and rest first."

Roy turned around and left, not giving the others a chance to say anything.

The trio wanted to say nothing but nothing, so they sighed, shook their heads, and left.
