"Let's go back to the house first, I guess the meal is ready, let's eat first! I'll teach you slowly after eating. Hurry/" Listening to Chilly's babble for half an hour, Harry felt a little hungry.

"Don't eat! Don't eat! You learned space magic so quickly, I can't lose to you!I decided to learn the sword art in 10 minutes!" Chilly refused, yelling that he had to learn it immediately.

Ignoring the old man's nonsense, Harry walked to the city on his own, muttering, "I'm hungry, I'll go back to eat first." 10 minutes?I can do it, but if you lose face, I'm the one who loses face!"

It's not difficult to control the flying sword with this swordfight. It's nothing more than a fireball boost, and the levitation technique grasps the balance. But if you want to be completely obedient to the flying sword, you can't do it without a little knowledge of mechanics. Harry was sure that this old guy would have made the flying sword spin in the sky as soon as he got his hands on it, and wanted to use it to attack the enemy.

"Good boy, you want to play tricks!" Harry made it clear that he looked down on himself, only to make Chilly scream in anger. Seeing that Harry ignored him, his hand moved slightly, and he used the Wind Binding Technique that had trapped Harry in the past!

This time, instead of getting caught up in the hurricane like last time, Harry flashed lightly and was 200 meters away. Teleport!Harry tried a little, and the first practice was successful, Harry couldn't help but be overjoyed, with this move, combined with the sword technique, he was basically invincible! No matter how fast he was, could he be faster than teleportation?

It's a pity that this move consumes about 10 of your mana, which is really costly.

At this time, Chilly also rushed up, looking unwilling to give up.

“...... Old man, do you understand that force is reciprocal? Do you know what impulse is? Do you understand leverage?" Harry asked three physics terms in a row, and Strange shook his head again and again.

"Isn't that it, you don't even know the basics, and you still want to learn the art of swordsmanship in 10 minutes?" Harry despised Chilly fiercely, he was really hungry......

"You say it first, if I really don't understand it, I'll let you go to dinner, I've been immersed in the ** method for so many years, isn't your comprehension of magic as good as you?!" Unfortunately, the principle of swordsmanship comes from physics, not magic, and Chilly is destined to make a fool of himself.

"I'm too lazy to talk to you, let's teach you first, what is the effect of force is mutual, if one object exerts a force on another object, then both objects must be subjected to the same force at the same time, and in opposite directions!" After saying this, Harry pushed Killy, almost causing Killy to fall to the ground.

"Hey, boy, what kind of name are you? You said that the effect of force is mutual, so if you push me, it means that I push you? This is obviously not right, it seems that I am the only one who suffers, wait for me! You have to make it clear to me today. Chilly shook his head and thought about it, and suddenly became confused, and hurriedly chased after him.

Harry performed another teleportation, this time a full 500 meters, and Chilly gave himself a blast to follow. Suddenly, he came to his senses and shouted again and again: "How can you spread so far? It seems that your spiritual power is not so strong as mine! Could it be that you have discovered some secret...... I won't let you go until you make it clear......"

When the two of them returned to the house, they saw that there were other people there, and Chilly restrained himself a little, but he still pestered Harry from time to time, and he had to explain it clearly.

Tang Ling had already prepared a sumptuous meal, which immediately made Harry's appetite move. Even when Chilly smelled the fragrance, he suddenly felt hungry, and immediately took the food and ate it in a big gulp, regardless of his image.

Everyone looked at each other and smiled at the appearance of this tired legend of the wizarding world eating, it seemed that this old man was not much better than a beggar except for his magical attainments.

After eating and drinking, Chilly came up again. Harry knew that he would not be able to concentrate on the magic of spatial teleportation if he didn't give him an explanation, and although the teleportation just now was successful, it was just a trick that Chilly had taught him. It's not like I've truly comprehended space magic.

The two of them arrived at Harry's magic training ground, and Harry began to explain the mysteries of the sword art to Chilly.

First of all, this sword art was not controllable by any sword, so Harry had to lend his dragon sword to Chilly for experimentation. When Killy heard about the design of the Dragon Sword, he was not only amazed, but Harry's idea was really imaginative, unbelievable!

As for the momentum that a fireball explosion can provide, this Chilly had learned it from the first time he fought Harry, but he didn't know how the same magic could provide this momentum to the fullest. So when he heard about the structure and function of the Dragon Sword, he shouted that he had learned it.

But after getting started, he realized that theory is one thing, and practice is another.

A flying dragon in the sky, he made it extraordinary, although he couldn't compress fireballs, but his blazing fireballs were also much smaller than ordinary fireballs, but they were more powerful than Harry's compressed fireballs.

But after the flying dragon finished in the angel, the dragon sword was out of his spiritual power sensing range, and the flying sword turned into a waste sword.

He tried to swing the dragon's tail again, but the dragon sword immediately turned into a propeller, spinning constantly, and he didn't know how to make the dragon sword stop.

The simplest use of the flanks to move horizontally was also made diagonally by him!

After dozens of minutes of farce, Chilly had to admit that this sword art was indeed a profound science. He knew the function of each spirit stone, but he couldn't use them well.

So, he had to sit down honestly and listen to Harry teach him the basic theories of physical mechanics.

......

Four hours later, Harry finally breathed a sigh of relief.

Chilly wasn't too stupid after all, and although he had limited acceptance of the theory of mechanics, it was enough to use it to command the Dragon Sword.

The compression of mental power was originally taught to him by Chilly, so Harry did not hide it and told Chilly about the use of the mental power net. In this way, Killy's range of control was extended to 500 meters. It is not easy to cast a flying dragon in the sky, and it will fly out of the sensing range at once.

Then, he understood the inertia, and that move not only needed to provide the power to spin at first, but also needed the same reaction force to stop him.

And with the lateral traverse, it is also necessary to use the same reaction force to make the flying sword no longer deflect after it is in place.

With these basic theories, the rest is just proficiency.

The sword technique is actually the same as Ling Bo's microstep. One is to use the levitation technique and rocket art to make the sword, and the other is to control the people.

The difference is that when controlling people, the human body can adjust its movements, posture, orientation, etc. by itself. Edgeworth, on the other hand, needs to use the auxiliary power of the wings to adjust it with the levitation technique.

Adjusting the human body is simple, adjusting the sword body...... Difficult!

Therefore, just like Harry's Limbo microstep, this sword art also requires a lot of time and practice to command the dragon sword like an arm. Swordsmanship is not limited to stabbing, slashing, and slashing, but if you want to make flying swords more flexible, you need to be familiar with the feeling of flying swords for a long time and form a proficient habit.

In the early days of Edgeworth, the cost of mental power was quite staggering, and after trying for an hour, cold sweat broke out on his forehead, and his spirit collapsed. The gap between Chilly and Harry can be seen here.

Harry can cast at least 10 spells at the same time, because Harry's consciousness body is a fusion of two beings, so he can control twice as much magic with the same mental power. Chilly's mental power is slightly inferior to Harry's, and he can only cast 4 or 5 spells at the same time.

Because of this, casting 4 or 5 spells at the same time is the most basic requirement of Edgeworth, and Chilly is almost full of energy. Harry, on the other hand, only needed half of his mental power to control the flying sword. That's why Harry readily agreed to teach Killy the art of swordsmanship, as he couldn't outdo himself. Edgeworthiness ...... Doesn't look at the level of magic at all.

......

Finally got Chilly, and Harry was able to practice his space magic.

First, Harry opened a spare room to use as his own storage room. Then he asked Qili for a good quality magic crystal to use to make a spatial coordinate marker. I have to say that this old guy still has a lot of good things.

According to the spiritual imprint magic taught by Qili, some spatial elements were arranged into a special formation, and then sealed in the magic crystal. Magic Crystals do not repel elements of any attribute, nor do they exclude spatial elements. In this way, a spatial coordinate ID is complete.

Harry placed a few random items in the room while he walked outside the house. As soon as his mind moved, Harry immediately immersed himself in a special meditation.

In ordinary meditation, the spiritual power is emanated, and everywhere you go, you must only sense the four elements of magic, so that meditation is the most effective, and the magic power can be improved the fastest. At this time, Harry's meditation was in the place of induction, and he could only feel the spatial element in order to be successful.

But it wasn't too difficult for Harry, who had already managed to reach that level on the way back.

Wherever the spiritual power passes, it is boundless, and all of them are spatial elements, and his spiritual consciousness seems to be in the vast mist, as far as the eye can see.

If it is a meditation of the magic element, it is obvious that the spiritual power can only be limited to the distance of the three-dimensional space, that is, how long your spiritual power can extend, then you can only feel the magic element in a certain range. The stronger the spiritual power, the greater the range that can be perceived, so the more magical elements there are, and the faster the natural cultivation of magic power.

But the spatial element is different, it can transmit spiritual power, the spatial element is boundless, and the extension of Harry's spiritual power is also boundless, but it is limited to sensing the spatial element.

In the vast white mist of space, the spatial logo with Harry's own spiritual imprint shone like a bright light, allowing Harry to quickly catch it. Although Harry was only a few dozen meters away from that room, in the white mist space, he didn't know how far away. The distance between the four-dimensional space and the three-dimensional space is really very different.

The tiny, almost void white dots that formed the white mist were spatial elements, and Harry was able to mobilize them very early, and it didn't take magic to mobilize them, only mental power.

Between the two points where he was and the spatial sign, a bridge similar to a passage was erected using spatial elements, and Harry reached out and grabbed a chair in the room.

That's when Harry finally understood where his magic was being consumed. And why teleportation is much more expensive than space grabbing.

The passage erected by the spatial elements is actually to connect one's own location with the location of the spatial identity in the four-dimensional space. With his own hands, he passes through the four-dimensional space through the passage erected by the spatial elements to obtain the objects in the room. And the magic is to provide the energy of your own hand through the four-dimensional space!

This kind of teleportation is easy to explain, in fact, it is just the transfer of one's whole person from the four-dimensional space to another point. Isn't the mana consumption of teleporting half a hand and teleporting the whole person more than ten times the difference?

Harry's heart fluttered when he thought of this!

Outside the room, Harry's figure disappeared in an instant, but Harry's figure was visible in the storage room.

And so it was...... There are no limitations to teleportation, and theoretically, you can teleport anywhere in this world......

As long as the passage is set up with the spatial element, Harry can use the passage to move in four dimensions. But you don't know where the other part of the passage is without a spatial marker!

In four-dimensional space, there is no distance, no direction (and even if there is, it is not the kind of cognition in three-dimensional space), you may think that you are teleporting a few hundred kilometers to the south, but in fact you may only move one meter to the east. And you think that you teleported two meters in front, or thousands of kilometers in the rear.

In short, teleportation without knowing the destination is extremely dangerous! Perhaps, you will be buried in the ground...... Perhaps, you will fall into the lava...... Perhaps, you will drown in the deep sea...... Maybe even go straight into the belly of a certain monster. This risk cannot be taken casually.

Finally, Harry had a complete understanding of space magic. With a solid knowledge of space physics, using space magic is nothing more than a piece of cake!

Tang Ling seemed to be chatting with Senny in the bedroom, and Harry's mental power swept the room slightly, and he had a general understanding of the situation inside. A mischievous smile appeared at the corner of his mouth, and he quietly cast a spiritual imprint behind Tang Ling to create a temporary space mark, and Harry disappeared into the storage room in an instant.
