Hogwarts: You are a devil!

Especially with George Pearl in front of them, after seeing his miserable state, the little lions became even more afraid to provoke Professor McGonagall.

Wood took Louis with a magic broom, placed him on the lawn 30 meters away from Professor McGonagall, and then ran away on the broom as if he was escaping.

"You prepare first, and we will start when you are ready. Don't worry, there is still a lot of time." Professor McGonagall said in a comforting voice to avoid Louis being nervous.

If she scared away Louis, the only one who dared to come forward and fight her, Professor McGonagall doubted that she would be able to meet the next challenger.

Louis nodded, took out the dragon wand, adjusted his breathing and lowered his center of gravity, prepared for battle, and said:

"I'm ready, Professor McGonagall!"

"Okay, don't worry, I'll attack you later. I'll only use magic to defend, so I won't hurt you!"

Louis raised his wand in front of him and bowed to Professor McGonagall. After completing the wizard duel etiquette, he whispered the sleeping spell:

"Passed out!"

The top of the wand emits a strong red light, and the sleeping spell beam flies towards Professor McGonagall, who is 30 meters away.

The sleeping spell is a relatively difficult spell. It needs to be aimed directly at the person being cast. If there is a slight deviation in the right hand, the spell beam may miss.

"Weeds change!"

The weed transformation belongs to the plant transformation spell branch and is a member of the herb transformation spell. Also belonging to the herb transformation spell are rose transformation, rose transformation and other transformation types.

A green grass quickly grew into a giant weed more than two meters tall with no gaps between the leaves.

At the narrowest point, there are [-] centimeter-wide weeds that just block Professor McGonagall's body. No matter what kind of light spell comes directly in front of her, it will be blocked by the weeds.

"In the discipline of transformation, the second most important school is called defensive counterattack flow, which transforms various creatures to bear the spell on behalf of the wizard, and then uses transformed creatures or magic to win."

Louis stopped casting spells in time to allow Professor McGonagall to introduce the defensive counterattack style.

Professor McGonagall, who had been paying attention to Louis' situation, saw this, and his love for Louis increased to a new level.

Brave and aware of the importance, he did not interrupt his introduction to the genre rashly. How great it would be if he were a Gryffindor student!

After feeling regretful for a while, Professor McGonagall continued:

"For example, now, I use the Plant and Tree Transformation Spell to block the Sleeping Spell. Next, I can prepare the magic leisurely. Come on, kids, let's demonstrate it to them."

After saying that, Professor McGonagall lifted the transformation spell she had just cast, and the grass between her and Louis instantly shrank to its original appearance, a young grass that had just sprouted.

"Fell to the ground!" The sleeping curse beam flew out again.

"Weeds change!"

After using the transmutation spell, Professor McGonagall silently recited the petrification spell and moved her body. At the moment when the petrification spell was ready to be completed, the wand just happened to circle the weeds and point at Louis.

A sense of danger arose spontaneously, and before Louis could react, the petrifying curse light pillar had already arrived at his feet.

The higher the level of the wizard, the stronger the understanding and mastery of magic spells, and the stronger the magic spells in the same state.

This is the petrification spell that Professor McGonagall cast casually. She only used the lowest ten points of magic power, but the power and speed of the spell were much stronger than Louis.

He was just a wizard apprentice when he participated in the wild hunt, and he was able to avoid Sophie's petrification spell by relying on his physical fitness.

Now he is a second-level wizard, and his physique is seven or eight times stronger than his original self, but he cannot avoid Professor McGonagall's petrification spell.

The petrified light pillar fell at Louis' feet. Centered on the landing point, the lawn with a radius of half a meter turned into stone, and even Louis' legs felt numb.

"In addition to using magic spells to counterattack, I can also transform a bunch of creatures that obey my command and let them attack Louis. This is the essence of the defensive counterattack flow, to counterattack the enemy while ensuring that I am not harmed."

"Oh! Professor, you are so great!" Professor McGonagall's explanation received a round of applause. It was the first time for the little wizards to know that there are so many schools of transfiguration credits.

Especially seventh-year Muggle wizards, who are about to enter society, have never heard of genres in the past 17 years.

In their impression, wizards fight with wands. Whoever's spells are more powerful and whoever has stronger magic reserves will win the battle.

Wizards from noble families were a little calmer. As early as when they were learning common sense in the magic world, their elders had explained the various mainstream fighting factions in the magic world.

Pure magic spell faction, transmutation spell faction, transmutation spell and magic mixed faction, alchemy and magic mixed faction...

Various factions fill the wizarding world. If you don't understand these factions in advance, you may be killed in the battle.

Never start a war with an unknown wizard unless you have a powerful family behind you!This sentence is common knowledge in the wizarding world, but for many Muggle wizards, they have never heard of it.

"Why is Professor McGonagall so crazy! She actually popularized the secrets of wizards to the mud-legged people. Damn it, doesn't she know that this is an established habit in the wizarding world!"

Deep in Slytherin Academy, several noble wizards looked at Professor McGonagall with gloomy faces.

Let Muggle wizards know all kinds of wizarding secrets, what qualifications do they have to maintain a sense of superiority in front of Muggle wizards, damn Professor McGonagall!

Those who have the above idea are a group of small family wizards, similar to the 28 pure-blood wizards who dismiss it.

It's just a little secret, and it doesn't pose a threat at all to them who control the lifeblood of the British wizarding world.

"Go on, kid! You're welcome, feel free to use the magic spell to attack me."

"Okay Professor McGonagall, please be careful! Cliff Sword!"

Professor McGonagall herself said you're welcome, and Louis simply used the Earth Stab technique.

Spells on the ground can be blocked with plants, but can you also use transformation to block the spells coming from below the ground?Louis thought with a smile.

Professor McGonagall was stunned. When she was young, some old wizards from the early [-]th century liked to use the Earth Stab technique.

Not since her first year at Hogwarts as Professor of Transfiguration had she heard the terrestrial spell.

Modern wizards, even Professor Flitwick, the master of spells, prefer to use instant spells such as light beams, rather than material change spells closely related to transfiguration.

She quickly reacted, pointed her wand at the ground beneath her feet, and cast a material-changing spell, the Clay-Iron Exchange Spell, to transform the ground beneath her feet into hard iron.

The sharp ground thorns pressed against the iron block, raising it along with Professor McGonagall by more than ten centimeters. The ground thorn technique failed.

"The ground stab technique used by Mr. Louis, and the magic spell I just used, are the last major school of transfiguration, a school of material transformation that was very popular in the past."
