Hogwarts: You are a devil!

"The material change flow is good at changing the properties of objects. The most commonly used ones are air and the magic in the air. Use magic spells to transform them into flames or ice." Professor McGonagall introduced.

The Fire Curse, the Fire Curse and the Obstacle Curse are all material change spells. In some wizard planes, this type of wand also has a well-known name, that is - shaping spells.

"Do you know any other material-changing spells? Use them and let me see."

Professor McGonagall asked in a low voice. Since Louis can use the ground stabbing technique, Professor McGonagall believes that Louis can also use other transformation spells.

Recite the Ice Cone spell, and use the right hand holding the Dragon Charm to perform the Ice Cone spell-casting movements according to fixed gestures.

Three ice picks nearly one meter long and ten centimeters thick at their thickest part appeared beside Louis. Under the control of his mental power, the three ice picks flew side by side towards Professor McGonagall.

"Very beautiful ice pick technique!" Professor McGonagall praised.

She turned the air in front of her into an earthen wall. After blocking three ice picks, Professor McGonagall dispelled the wall, put her wand against her throat and said:

"Ice cone, a transmutation spell that changes the magic in the air into an ice cone. Around the [-]th century, it was one of the most commonly used spells in the entire wizarding world. It is ranked as the three must-have spells along with the fire spell and the petrification spell."

"It's a pity!" Professor McGonagall's tone suddenly changed: "The process of using the Ice Cone Technique and the Ground Sting Technique is too cumbersome, and has gradually been replaced by the popular magic spells."

Her face was full of disappointment. As a wizard whose main research direction was transfiguration, or the deeper science of shaping, Professor McGonagall was extremely yearning for the sixteenth century.

The magic power consumption is huge. Just condensing three ice picks requires Louis 27 magic points. It also needs to be guided by the spirit. Without guidance, the ice picks cannot even move autonomously.

No wonder the ice cone spell was eliminated by wizards in favor of light spells that cost less and are easier to learn and use.

"Go on, I'll give you a little suggestion. Don't give up on these magic spells. When you study deeper, you will find that the Transformation Flow Charm can do many things that existing magic spells cannot do."

The deeper the research goes, the deeper the understanding of the laws, and the greater the power of the Transformation Curse.

"Okay professor, thank you for your suggestion, I will continue to study!"

After speaking, Louis took a few steps forward. The casting range of the trap spell was much smaller than the other two spells. Louis needed to go 20 meters away from Professor McGonagall to cast it.

Take the initiative to come closer?Are you not familiar with magic spells?Or is it that the magic spell he wants to use has a distance limit?Questions flashed through Professor McGonagall's mind.

But when she heard the spell from Louis' mouth, Professor McGonagall instantly understood.

Louis wants to use the Earth Trap Technique, a magic spell that few people would learn when the material transformation school was at its peak.

After closing his eyes and using his mental power to determine Professor McGonagall's position, Louis used the Ground Trap Technique on the ground beneath her feet.

"What's going on! Is it an earthquake?"

The wizards in the stands felt the ground shaking. When they came to their senses and looked towards the center of the field, they found that the place where Professor McGonagall had been was shrouded in a cloud of smoke, making it impossible to see what was going on inside.

Then a wind blade visible to the naked eye flew into the sky, splitting away the smoke surrounding Professor McGonagall, revealing Professor McGonagall standing above the large hole.

There was an ice peony under her feet, and the branches made of ice spread downwards and disappeared into the six-meter-deep cave. The wizard robe on her body was as clean as before, and there was a smile on her serious face.

"Are there any other spells? Use them all and let me see!" Professor McGonagall said expectantly.

After experiencing the power of Louis's full-scale subsidence spell, Professor McGonagall suddenly had the idea of ​​​​accepting Louis as his apprentice.

Although this idea passed away briefly, it made Professor McGonagall more interested in Louis and wanted to know more about Louis' research on transfiguration.

"Um, I'm sorry, Professor, I don't have any magic power anymore." Louis put the dragon back into his wand bag, and a bit of regret flashed across Louis' face.

It would be great if he could use unlimited magic power like he did during the breakthrough. More than 100 points of magic power couldn't help but be spent. He only used five magic spells and fell into a state of no mana.

Professor McGonagall blushed slightly. She had forgotten that Louis was still a second-year wizard. He had limited magic power in his body and could not cast many spells.

"I understand, you should go back first and come to me when you are free!"

After giving instructions to Louis, Professor McGonagall used a loud spell: "Wood, come and take Louis back!"

Wood grabbed the broom and flew to Louis: "Come with me, hero. My name is Wood, a third-year Gryffindor student. My goal is to become an official Quidditch player!"

Wood showed great respect for Louis. Not only did Louis dare to fight Professor McGonagall, but his strength in the battle shocked Wood, making him subconsciously put himself in a weak position.

"The magic spell you used just now is so cool. Can you tell me what its name is?" Wood asked curiously as he flew to the stands.

"Ground Trap, a large-scale attack spell, you should be able to find it in the Hogwarts library!"

"Yeah, thank you! You can come to the Gryffindor lounge when you have time. You will be welcomed by everyone!"

After sending Louis back to Qiuzhang and leaving a thank you and invitation, Wood hurried away on his broom. He was going to show off to his good friends the name of the curse he had asked from Louis.

"Does anyone else want to challenge me? The time is limited. The challenge will be over after noon today!" After restoring the big hole to its original state, Professor McGonagall shouted confidently.

"I come!"

"Professor McGonagall, I am your loyal fan, please choose me!"

""

After watching the entire challenge process, the wizards had a deep understanding of the extent of Professor McGonagall's actions.

He won't hurt himself or embarrass himself, and he is still a professor-level figure. In the entire wizarding world, I'm afraid not many people have the treatment of a professor.

Qiu Zhang raised her hand equally excitedly. She wanted to fight Professor McGonagall, who was called the strongest witch in Britain. Unfortunately, Professor McGonagall did not choose her, but chose a Gryffindor student.

After all, this is his own college. As the dean, Professor McGonagall is naturally more partial.

"Hmm! Why not me!" Qiu Zhang lowered his head depressedly.

"It's okay. Didn't Professor McGonagall say that the challenge lasts until noon? It's only 10:30 in the morning. There's still more than an hour left."

He sighed helplessly. As a boy and Qiu Zhang's godbrother, he couldn't see Qiu Zhang sad. Louis could only step forward to comfort him.

If it were an ordinary girl, he would have told her to get away as far as she wanted, and not to let her being around him affect her mood.
