The God of Ice and Fire at Hogwarts

After arriving in the secret room, Green began to teach Linn.

First of all, what Green taught was the secret method of carving alchemical circles without the need for a carving knife. This secret method required powerful magic power to support it.

And Lin En, who has the power of the devil and the magic stone as an energy source, will naturally not lack such things as magic power.

I saw Lynn raising his right hand holding the wand, a strange wave of magic power spread out, a steady stream of magic power was injected into Lynn's body from the Philosopher's Stone through the authority of the Demon God, and a highly absorbent magic power was released from the magic wand. It was slowly spit out and condensed into shape on a metal plate in front of Linn.

"Very good, this is the first step. Let the magic power be strongly adsorbed on the alchemy object so that it will not dissipate."

Green nodded slightly.

Under Green's teaching, Lynn gradually became familiar with the alchemy method of replacing the carving knife with a wand, and he quickly drew an alchemy circle on the metal plate with the wand.

Yes, draw!

Unlike the method of engraving magic power into the surface of the alchemy object with a carving knife, the magic power spit out by the wand is adsorbed on the surface of the metal plate by virtue of its strong adsorption, just like drawing on paper, so this method of alchemy uses drawing It seems more appropriate to describe it.

"Next, just like you cast spells without a wand, try to get rid of the wand and use your body to release the same adsorbing magic!"

Green continued to guide.

Although the teaching has been considered a success when the wand is used instead of the carving knife, Green has higher requirements for his disciples. Only by relying on the body alone can he still refine the alchemy circle with his bare hands. , Lin En was able to rely on alchemy to save his life under any circumstances.

Linn nodded, put down his wand, and then tried to concentrate the magic power on his fingertips.

Alchemy does not require a wand, which is similar to the wandless spellcasting of the magic system. Lin En, who already mastered the technique of silent and wandless spellcasting, has a natural advantage in learning alchemy.

In just over half an hour, Lin En was able to refine the alchemy circle without relying on any external objects!

"Okay, the next step is to refine the alchemy circle out of thin air!"

Green nodded with satisfaction and said.

Compared with refining an alchemy circle from foreign objects, the difficulty of refining an alchemy circle in the air is not at the same level.

It's like the former requires you to dip your hands in ink to write, while the latter requires you to write on the air.

"Refining the alchemy circle out of thin air requires us to condense the magic power in the air without dissipating it. In the absence of a carrier, we can only make the magic power itself a carrier. That is to say, we need to compress the tangible but intangible magic power For tangible and qualitative magic!"

Under Green's narration, Lin gradually understood the key technique of this secret method, which is to compress a large amount of magic power into a small ball of magic power, making this ball of magic power rich enough to become a real substance.

However, if the magic power is forcibly condensed, the magic power required to achieve tangible and qualitative levels is massive. If you want to condense a qualitative magic power the size of an apple, I am afraid that you will need to consume a magic power group the size of a swimming pool!

At this time, it was necessary to use the secret method taught by Green. Under the influence of the secret method, Lin En was able to condense the qualitative magic power more easily. Lin En waved his wand, and a thread of qualitative magic power appeared. Speeding through the air, it finally formed an alchemy rune.

"Let's stop here, you already have the ability to refine the alchemy circle out of thin air, as for the practice, wait until tomorrow, I'm afraid you have reached the limit!"

Seeing Lin En draw the alchemy runes, Green decisively stopped Lin En's next move, pointed to the fine beads of sweat on Lin En's forehead, and said so.

Hearing this, Lin En scattered the alchemy runes in the air with relief, staggered and sat on the ground, panting heavily.

As Green said, under these seven or eight hours of study, he has reached his limit.

Although the Sorcerer's Stone powers him, the excessive magic power carried for a long time has already put a huge load on Lynn's body.

Lynn looked very tired, but his face was full of excitement.

After two and a half days of rest, Lynn and Green came to this secret room again.

Lin En resolutely skipped the step of using the wand to refine the alchemy circle out of thin air, and chose to directly start refining the alchemy circle without the wand.

I saw Lin En waving his hands in a familiar manner, and golden magical threads spurted out from the tips of his ten fingers, intertwined with each other in the air, and turned into alchemical runes. Then, more golden threads spurted out. Then, connect these golden alchemy runes in series or in parallel to form a complete alchemy circle.

Lin En estimated the carrying capacity of his body, increased the rate of absorbing the magic power of the Philosopher's Stone, and once again refined two alchemy circles out of thin air.

At this time, a total of three alchemy circles were suspended beside Lin En, as if they were guarding their king.

"Come on, try attacking me!"

Green stood tens of meters away, beckoning to Lynn.

Lin En nodded slightly, and with a thought in his mind, the three alchemy circles shot out countless golden beams like machine guns.

The golden beams emitted by these three alchemical formations are the same as Linn's alchemical floating cannon, but these three alchemical formations do not require a lot of time to accumulate power like the alchemical floating cannon.

If the alchemy floating cannon can only emit one golden beam every 30 seconds, then the alchemy circle around Lin En can fire up to 30 golden beams per second under the condition of sufficient magic power supply!

Countless golden beams of light turned into meteors all over the sky, exploding in Green's direction.

Facing such a terrifying attack, Green did not change his face. He waved his wand, and the same three alchemy circles formed around him in an instant, and also emitted a powerful golden light beam, which was similar to Lynn's. The golden beams collided with each other and canceled each other out.

Linn couldn't help but feel a little emotional when he saw Green repelling his attack so easily.

As expected of his teacher, the alchemy circle that he spent more than ten minutes refining could be formed in an instant with just a thought!

It seems that after refining the demonic power, Linn estimated that he could face Teacher Green without falling behind, but he still overestimated himself.

After all, even if he has the powerful silent and wand-casting flame spell, plus the magic stone as a magic power supply, I am afraid that before he has time to attack, the alchemy circle formed by the opponent's thought can smash himself into a sieve Got it!
