Hogwarts: I am the White Demon King

How long has he been holding back?!

Why is he so excited once he starts fighting?

Watching the aggressive Gryffindor, Sebastian stretched out his hands, making a stopping gesture!

"Stop!"

The sudden stop made Gryffindor, who was in the heat of battle, extremely uncomfortable.

He glared, his beard and hair all standing on end, like an enraged lion, roaring at Sebastian: "What's wrong, kid?"

"Don't you even have the courage to fight me?!"

"You're making me too disappointed!"

Sebastian quickly waved his hand and said, "I just think your teaching method is too inefficient, and I want to change to a different learning method."

Hearing Sebastian dislike his teaching method, Gryffindor immediately became so angry that smoke came out of his ears and he jumped up and down.

"Is that so?" Gryffindor's voice was unreadable. "Then please, this master, enlighten me on how I should teach?"

Sebastian could easily hear the sarcasm in the other party's words, but he knew his own limitations.

As long as it was a spell, he had his own unique learning technique—100% imitation!

Relying on his unique magical perception talent, as long as someone cast a spell in front of him, he could quickly imitate it.

He smiled slightly and boasted to the angry Gryffindor.

"You can just demonstrate the casting process to me once, and I can learn it by watching."

Learn it after watching it once?

Bah!

The Slytherin kid is just slippery!

He's definitely afraid of getting beaten up!

Seeing Gryffindor's 'keep dreaming' look, Sebastian quickly said.

"I guarantee, as long as I watch it once, I can learn your spell stacking technique!"

"Impossible! Absolutely impossible!" Gryffindor waved his hands repeatedly. "It would be a gift if you could learn it in three days."

"Being able to learn it in two days would be top-notch even in our time."

"If you can learn it in one day..."

"What if I learn it in one day?" Sebastian asked curiously.

"I'll give you a thumbs up and say 'Good job!'"

Gryffindor rolled his eyes: "I've taught many students this trick."

"Very few can learn it in three days, and most students can't master this technique in their entire lives."

"As for what you said, learning it after seeing it once? Heh heh..."

Seeing Gryffindor looking up at the sky, appearing unyielding, Sebastian took a step forward and used the always effective provocation method.

"What's wrong? Teacher Gryffindor, don't you even dare to try?"

"No way! No way!" Sebastian instantly transformed into a 'green tea'.

"The dignified founder of Hogwarts, doesn't even have the courage to try!"

As soon as these words came out, Gryffindor's face immediately darkened.

His magic boiled again, wave after wave pressing towards Sebastian.

Daring to question his courage, what audacity!

"I'm warning you, if you don't learn it after watching it once, I'm definitely going to beat you up to vent my anger!"

"You should know that during the teaching process just now, I didn't cast a single spell at you, I was just purely playing with you using fighting skills!"

"Watch carefully, kid!" Gryffindor tried his best to suppress his anger, "I'll slowly demonstrate it to you once, you must watch carefully."

Although he was annoyed, his movements were meticulous, and at the same time, he explained the key points without reservation.

"You need to pay attention to the ending movement of the first Iron Skin Curse. When finishing, slow down the magic power, and then directly connect to the second Iron Skin Curse with absolute control."

"There are two difficulties here," Gryffindor glared at Sebastian, "The speed of slowing down the magic power and absolute control over your own magic power!"

"A little carelessness will turn it into releasing two separate Iron Skin Curses!"

"Don't take it lightly," Gryffindor raised his voice again, "This is just the first step, the foundation of the foundation, the next step is the key."

"Spell stacking, the key lies in the word 'stack'. Watch my technique!"

Sebastian didn't dare to be careless about Gryffindor's personal teaching!

He stared unblinkingly at Gryffindor's every movement, and at the same time, he opened his magic perception to the maximum to carefully experience every trace of magic flow.

In his perception, Gryffindor meticulously controlled every movement, like a mighty strong man embroidering with a needle.

The Iron Skin Curses were stacked one layer after another, staggered and orderly, like exquisite works of art, beautiful and generous.

Sebastian had a flash of inspiration.

How could this layering technique be so similar to the technique of drawing magic circuits in alchemy?!

No wonder it's so difficult...

This spell stacking is just alchemy in the guise of a spell! If you don't have some basic alchemy knowledge, wanting to learn this spell stacking is simply a fool's dream.

However, no wonder the defense of spell stacking is strong.

This is like chain mail among Muggles. Gryffindor used a single Iron Skin Curse as the foundation to weave a powerful armor unique to wizards!

Truly amazing!

Gryffindor deserves to be one of the most famous wizards in wizarding history.

Only now did Sebastian truly realize the weight represented by the four words 'Gryffindor'.

"Okay, pay attention to the technique of this last step!"

Gryffindor's shout pulled Sebastian back from his thoughts. He looked up and saw that the ninth Iron Skin Curse had reached the finishing movement.

As Gryffindor's wand shook, the ninth spell was completely completed, and together with the previous eight Iron Skin Curses, it was completely connected to form a whole.

"This is spell stacking! Nine Iron Skin Curses connected into one layer, the more layers, the stronger the defense!"

"Theoretically, you can stack it infinitely, and your defense can become infinitely strong!"

"But be careful, for every layer you add, your control must be several times stronger!"

"A little carelessness will lead to failure."

Speaking of this, Gryffindor stopped and looked at Sebastian meaningfully.

"Do you think it's extremely troublesome, and besides being stronger in defense, it's not as flexible as a single Iron Skin Curse?"

Sebastian nodded, deeply agreeing.

In actual combat, where would there be time to stack spells layer by layer, and one mistake would lead to failure.

Impractical!

Really not very practical!

Is this some outdated ancient magic?

Unless... this kind of spell stacking can be prepared in advance and exist for a long time!

Seeing Sebastian's look of sudden realization, Gryffindor smiled happily.

"Although it's troublesome, once the spell stacking is formed, it will form its own magic circuit, and then absorb the magic power in the air and continue to exist stably."

"You can prepare in advance and stack several layers."

"Usually it is hidden by your side and will not affect your daily life. It will only appear when attacked, or when you actively summon it!"

"How about it? Isn't it very powerful?"

Only now did Sebastian understand the importance of spell stacking—infinitely increasing defense.

And it can be prepared in advance!

In this way, it is really ridiculously strong!

This is an invisible protective tool that can always be strengthened!

Gryffindor, from today onwards, this spell will be renamed Swan!

Looking at Sebastian nodding like a chick pecking at rice, Gryffindor felt very proud.

He stroked his beard and then teased Sebastian: "Come on, this master!"

"Please begin your performance!"
