"Professor, since you have divided the intensity levels of magic spells, what about the spell itself? Does it also have levels?"

The students below accepted William's theory after a while of surprise, and immediately some people came up with their own new opinions.

Although the self-defense education courses at Hogwarts are terrible, the systematic education of magic still allows them to have enough knowledge reserves to understand new knowledge.

"Excellent question, two points for Slytherin."

William nodded towards the child who asked the question. Although it is not difficult to make this association, the only children who can do it so quickly are the children in Slytherin who have learned a lot. Compared with other houses, Slytherin has such a strong sense of level.

This kind of thing is more important.

"Although I really want to tell you that there is, in fact, from my personal understanding, there is no absolute level difference in magic."

"No?"

The students were all excited. Compared with the previous theory that seemed acceptable, the professor's new point of view simply subverted their previous understanding.

"Yes, no."

William smiled and repeated that those professors' remarks about the club inspired him no less than a rare book on black magic.

"I think you all are not used to this - after all, everyone is learning year by year, and the magic to be mastered is becoming more and more difficult every year. Even a brief analysis of the subsequent magic is very difficult, let alone using it.

Already."

"Or maybe you have already graded your spells privately, so that first-year students are Level 1, and second-year students are Level 2?"

He looked at the students with a smile, and many of them showed hesitation - obviously, this was how they divided themselves in private.

"It seems very reasonable. Spells that are difficult to learn are high-level magic, and magic that is easy to learn is low-level magic. It is very reasonable - but is it really like this?"

William looked around at all the students, who all looked back with confused expressions.

"Who can tell me what spells were taught in the sixth grade spells class recently?"

"Cure Water Like a Spring, Professor."

A Gryffindor kid rushed to answer the question, and then realized something was wrong.

If the spell "Clear Water Like a Spring" is divided according to grade and learning difficulty, it is obviously a standard sixth-level spell - but how is this possible!

The surrounding students were also stunned. They all learned the same set of magic from the same professor. Some people haven't mastered this magic yet, but if they were to think that clear water like a spring was a level six spell, they would be really joking.

Even for the best students, the effect of using this spell is to summon a spring of water - it has no lethality, no defense, and no special function. It cannot surprise people like transfiguration, nor can it be like those complicated potions.

It has an effect that can be called a miracle in the magic world.

If this kind of magic is promoted to the sixth level of magic, how should the other spells be calculated...

"So, Professor, are all magics equal?"

In the case of clear water, a Hufflepuff child reluctantly asked the question that he was unwilling to accept.

"I dare not say so, but except for a few magic and black magic, most of the other magics are not as different as you think."

William took out his wand as he spoke, "Here, raise your wands, let's do an interesting experiment."

Although they didn't know what the professor planned to do, everyone became excited all of a sudden - they had done the papers too many times throughout the year, and a class where you can use a wand is a good class.

"Move the table aside first. We don't need notes for this class yet. I need time to perfect my immature theory, and you also need time to find evidence that can refute me."

While watching the students move tables awkwardly, William shouted to everyone in a serious tone.

"Don't think I'm joking. I'm here to announce that if someone can come up with a complete theory that can be justified and refuted my point of view before the end of this semester, you will not only be able to get the qualification to be exempted from the final exam, but also

Get one of my spells directly, I believe, it's definitely an exclusive spell."

"Of course, you can also give up the spell in exchange for three hundred galleons - I hope you choose this option."

The reward from the professor made everyone go crazy. They all paid 12% of their attention to listen to every word William said - after all, the professor's theory was too ridiculous and seemed too easy to refute.

"Russell, come to the front," William randomly nodded. The child was stunned for a moment and immediately ran to the front.

"Attention, I am going to use the disarming spell. You can attack or defend."

"Yes, Professor!"

His reaction speed was very fast. When he answered yes, he quickly pulled out the wand and cast the spell directly on William.

However, before his stun spell could hit William, his wand had already flown into the air.

"Excellent," William praised as he leaned close to avoid the slightly slower stun spell, and then directly caught the student's wand firmly.

He waved his hand casually, and the wand flew straight towards its original owner. It slowed down and fell down the moment it approached.

"The disarming spell," William turned to look at all the students, "This is a magic that can be mastered by lower-level students. Too many wizards have fallen victim to this magic. Losing their wands is not a good thing for wizards."

"But he seems to be easily resisted..."

"Of course, if this kind of magic is not easy to block, then I guess everyone will be forced to learn it on the first day of school."

"But...Professor, does this have anything to do with your theory?"

Another child boldly asked.

"No, it doesn't matter too much." William shook his head gently towards the child who asked the question, "The disarming spell just now is just a disarming spell that meets the qualified standards."

"It's called the Disarming Curse, not the Wand Disarming Curse, and it's not a flying curse that targets magic spells."

"Of course, when I say this, I don't mean that research on it will definitely not increase its power. There are too many directions in which a magic can be researched and improved. What I am going to say below is just my personal opinion. Although it does not increase its power,

but…"

William began to inspect the classroom. Under the puzzled gazes of all the students, he quickly targeted a spider.

"The experiment below is a bit too inconsistent. I hope you will not think of using such spells on wizards, Muggles or other intelligent races in the future - if something like that really happens, I think I will give up my professorship.

Applicant for Auror position."

While William spoke seriously to all the students, he used the flying spell to summon the spider.

"Everyone, watch carefully."

He stopped the spider in the middle of the desk and shouted to the students.

Then, a piece of parchment was taken out and placed on the table.

William tapped the parchment with the fingers of his left hand, causing it to quickly enlarge to cover the entire podium. He waved the wand with his right hand, making the spider stop on it.

Then, William flicked the spider with his wand, causing it to expand rapidly to ensure that everyone could see it clearly.

At this moment, some people had already let out exclamations that were interrupted by them.

"I repeat again, during my tenure, if any graduate uses similar spells on intelligent creatures, I will deal with that student responsibly."

William raised his wand in front of everyone as he spoke, "Watch carefully!"

"Expelliarmus!"

The disarming spell that everyone was familiar with had the same light and the same spell. However, in everyone's surprised eyes, one of the spider's legs was torn off and flew towards the professor.

William stirred the wand slightly, and it immediately landed on the podium faster than before.

"With a slightly improved spell, if you change the definition of the weapon, you will get a pretty terrifying attack effect."

For a moment, there was silence in the classroom, with only the sound of breathing remaining.

"Then, Professor...if a wizard loses his wand, wouldn't his weapon be his fist..."

A Ravenclaw child reacted almost instantly. He couldn't help but interrupt himself in the middle of his conjecture.

"The same effect is the flying curse..."

William took a breath, then raised his wand again, "Spider legs are coming!"

In full view of everyone, the other leg of the spider twisted into a weird angle, then separated from its original body and flew towards William, but was knocked back to the podium again by William.

This time, not even the sound of breathing could be heard in the classroom.

"More than that," William looked at the student, "When you have enough knowledge and understanding of a spell, you can modify it according to your understanding... Of course, violence is not the only method, and some modifications are even just

In order to weaken the power of the spell, or in other words, enhance certain effects."
