On the other side, Dumbledore and Lin Yi had quietly disappeared into Hogwarts.

When they reappeared, the two were already standing on a high reef.

Next to the reef is a rocky beach composed entirely of hard reefs, with strangely shaped hard reefs scattered across the shallows and water, at the mercy of waves crashing against each other.

The cool sea breeze blows from the surface of the sea, with a hint of salty smell belonging to the sea.

Looking at the scenery in front of him, which had changed in an instant, Lin Yi showed an interested look on his face.

"Is this apparition?"

"That's right."

Dumbledore laughed and jumped off the reef and walked along the rocky beach.

Lin Yi also jumped down, looking around with interest.

When he first arrived, he thought it was the rocky beach where Voldemort hid his fake Horcruxes, but upon closer inspection, it seemed to be just an ordinary rocky beach.

"That's a good way to get there, can I learn it?"

Lin Yi, who followed up, made no secret of his interest in phantom shifting.

But alas, Dumbledore shook his head with some regret.

"I'm sorry, Lin, you shouldn't be able to...... It's not that I don't want to teach you, with your abilities, you should be able to feel what's going on in the apparition process, right? ”

Lin Yi nodded lightly, and there was not the slightest surprise on his face.

At the moment when the phantasmagion shifted, he clearly felt the crazy flow of magic in Dumbledore's body, and that kind of flow was like a flood, even Dumbledore was a little caught off guard, and he didn't have time to hide it at all.

With Dumbledore's proficiency, this level of apparition would have been a breeze, and nothing like this could have happened, so...... This happens, apparently because of yourself.

After his gaze swept over Lin Yi, Dumbledore couldn't help but sigh.

"The Celestial Master is like this, and so are you, your size is too large, even if you use the magic power that is most suitable for phantom transformation as the medium, there is still a huge amount of consumption, not to mention your Qi."

"What if I can guarantee that Qi is enough?"

Lin Yi asked a question again.

"Lin, you still haven't understood." Dumbledore shook his head, "The consumption of Qi is not the crux of the matter, this is just a description of your size...... If we compare space to the surface of water, phantom shifting is the equivalent of diving into the water from one place on the surface, then swimming to another surface and then re-emerge. ”

"In this process, the spirit is your motivation, the physical body is your volume, the larger the volume, the wider the water surface you will contact when you dive, and the stronger the resistance of the space to your apparition - this is a self-protection mechanism formed by the world against us, in other words, the illusion is only suitable for wizards like us who are strong in spirit and weak in body."

At this, Dumbledore paused slightly, and then said softly.

"Of course, there are also some spells involving space in the Qimen on your side, which can allow some very powerful people to travel through space, but according to my research, most of those spells are very domineering, and almost every one of them will cause some degree of damage to the world itself, although it is very slight, but damage is damage, and this cannot be changed......"

Lin Yi nodded knowingly when he heard this.

He knew what Dumbledore meant, but he didn't expect this guy to be an environmentalist.

Lin Yi was not too surprised by the spells that Dumbledore said would cause damage to the world, thinking about the Eight Wonder Techniques and the cultivation principles of many mainstream sects, this was indeed irrefutable.

Dumbledore may not be able to understand it, but the phrase "the creation of heaven and earth, the mystery of invading the sun and the moon" has always been a matter of course for the cultivators of the Central Plains.

"And how did you bring me here?"

"It's a tricky way." Dumbledore whispered, "The principle of apparition is to use our magic to transmit the scattered fragments of consciousness and mind from the space below the surface of the water to the desired destination, and then teleport ourselves in a teleportation state. ”

"In the process, those escaping fragments will leave an imprint in the space below the water's surface, equivalent to an identity certificate and pass, and when I took you with me, I deceived the space into thinking that you were also a part of me, so it lowered its resistance to us."

"Wouldn't that be damaging to the space?"

"Of course not, because my magic has paid for it."

Lin Yi nodded when he heard this, and then couldn't help but tease.

"The principle of phantom shifting sounds a bit like quantum transmission!"

This was originally a joke, but what Lin Yi didn't expect was that Dumbledore actually nodded.

"That's right, over the years, Muggle scientists have gradually figured out a hint of phantom shifting, which they call free-space quantum teleportation...... It has to be said that these Muggles are indeed some amazing and glamorous, and they have successfully found the most orthodox spatial teleportation method in the world. ”

Lin Yi tugged at the corners of his mouth.

Dumbledore's words were clearly praising scientists from all over the world, but in fact he was showing off the legitimacy of the apparition.

He stopped talking about the apparition for a moment, and instead chuckled.

"Professor, let's get down to business...... You've said you want offensive artifacts before, right? ”

Seeing that the main drama was coming, Dumbledore suddenly stopped.

"That's right." He turned around and looked at Lin Yi with a smile, "There won't be Muggles in a radius of ten miles here, and their satellites and surveillance can't see the situation here, just experiment here." ”

Lin Yi nodded, stretched out his hand, and a phagosac appeared in his hand.

The sword qi was running, and a flash of fluorescence suddenly lit up on the phagoagosac, and two identical long swords appeared on the ground in unison.

These two long swords were all branches that Lin Yi saw when making the Nine Dragon Swords, so he took a little effort to make these long swords.

As soon as the sword appeared, Dumbledore's eyes showed great interest.

In their case, ordinary wizards can actually make a lot of interesting magic items, but powerful offensive magic items are not so common.

There are three main reasons for this phenomenon.

One is because the production and use of powerful magic props are regulated and restricted by the Ministry of Magic, and the other is because the birth of powerful magic props has always been accompanied by great dangers, and they cannot be mass-produced as safely as the refiners in the East.

As for the third reason, it's a bit special.

Magical items made by Western wizards tend to have some random nature and have a very strong personal style of the maker, such as a map of the living spots that shows the location of everyone at Hogwarts, and a sorting hat created by the Gryffindor Four.

In such a situation, it is naturally difficult to craft powerful offensive magic items.

Although Lin Yi did not know the reason for this, it did not prevent him from selling his masterpiece to Dumbledore.

"This sword has the power of the hand."

Lin Yi said as he picked up the first sword on the left side, and then waved it.

A blazing flame rose from the base of the blade, enveloping the entire blade in an instant.

With another swing, a huge oriental dragon composed entirely of flames sprang out of the blazing flaming blade and swooped into the sea with a wave of boiling heat.

Snort –

The sea surface that was hit by the head-on burst instantly, setting off huge waves, a large area of sea water was instantly evaporated by the extreme high temperature, a large area of sea area boiled, and the hot water vapor instantly steamed on this tumbling sea, and was carried by the sea breeze towards the shore.

"Awesome!"

Dumbledore sighed with heartfelt emotion, and immediately raised the wand in his hand to calm the huge waves and block the sea breeze carrying the boiling water vapor from the two of them five steps away.

In just a few seconds, the sea surface that had been showing a violent posture suddenly returned to its previous calm and calm, and the sunlight reflected through the clouds rising on the sea surface into a clear and gorgeous rainbow.

All that remains is the sea with a few bubbles from time to time, and a steady stream of dead fish floating up on their stomachs, still showing the outside world the great danger hidden behind this beauty.

"You can call him the Fire Dragon Sword."

Lin Yi turned his back to the rainbow and calmly handed the blade in his hand to Dumbledore.

Dumbledore reached out and took the hilt of his sword, feeling the warmth at the hilt.

Seeing this, Lin Yi smiled and said, "I have used heat-insulating and heat-resistant materials for the hilt and handguard, even if there is no magic, it will not hurt its user because of this." ”

Dumbledore nodded, then looked at the remaining one.

Lin Yi picked up the second long sword again and reached out and pointed at the sea.

In an instant, the clouds and mist rising on the surface of the sea were suddenly absorbed and turned into a vivid water dragon, flying around Lin Yi and Dumbledore.

"This sword has the ability to harmonize, he can control the liquid water and gaseous water around you to a certain extent, but he can't control the solid ice, you can call him the Water Dragon Sword."

Lin Yi handed the second sword to Dumbledore.

Dumbledore reached out and took the second sword, holding the hilt of the sword to control the water dragon in the air to hover and fly, the fire dragon sword that was originally in his hand had disappeared at some point, and it was obviously collected by him into a space magic weapon.

"The advantage of these two swords is that they are powerful, the material is tough, and there is almost no threshold for use, even children who have just awakened their magic power can use it, and the disadvantage is that the magic power consumption is large, and the imitation control is difficult to ......"

Speaking of this, Lin Yi paused, and then showed a smile.

"I want to use two long swords, exchange some books that record powerful spells and the principles of magic spells, I don't want those popular textbooks in the library, I want a copy of the magic notes of a famous wizard, of course, your best!"
