This is what Ravenclaw looks like.

"Okay, I got it, Tyler."

Professor McGonagall nodded slightly, then turned to Percy and said, "You should go and rest first. You have been very busy during this period. Taylor, you can work overtime to complete the report."

Percy even secretly made a face to laugh at Andrew without the professor noticing.

But after the office door closed, Professor McGonagall sighed.

"The fight started again...once every few years..."

She held her forehead with her hand, "But we can't do anything, not even put in food. We can only give some advice before starting a real fire."

The professor looked at Andrew, "You should understand, Taylor - you Ravenclaw students always think more."

"You can probably imagine that after all, the range of the Forbidden Forest is limited, and there are only so many people it can support..."

Andrew shook his head - actually it has a lot to do with the rabbits in the Forbidden Forest of Hogwarts. If there are more rabbits, there will be more spiders and centaurs. And then if there are fewer rabbits, there will be no less spiders and centaurs.

The side close to the school is strictly prohibited from being stationed, and the other side also has an end - even the wizard's own life has area restrictions, let alone centaurs and spiders. To be more precise, they cannot release expulsion hemp on their own. Residential magic like melon spell.

The centaurs were better off. If Hagrid hadn't saved those spiders, they would have been targeted to control the size of the group. In fact, Hagrid was already very partial to the spider group.

There are some superficial differences between living in the Forbidden Forest and being kept in captivity - the centaurs would rather fight spiders than accept feeding. This is the last line of dignity.

Therefore, we can only watch the two groups fight over food and territory, and they can't provide anything - they can't provide weapons at all.

"There's still a lot left...but that's about it. Don't talk about these messy things in the school - they still have a lot of unexplored areas in the Forbidden Forest. If it really doesn't work anymore in the future, we can persuade them to move out by different groups. Part of it - this is the only way, not even Albus can conjure a living land out of thin air. "

Professor McGonagall nodded, "Okay, you can go and have some rest. Remember to fully understand Wagadu's spell system. By the time you reach third grade, we will officially start learning the art of human transformation - I'll leave it to you to understand." Time is running out for another system of knowledge.”

"I will study the basics carefully, Professor."

Andrew answered seriously, "Just, um, I think, just imitate the Iron Armor Curse - use the power of transformation, how about it?"

"Of course, you have a solid foundation now, but you need to be more serious about the magic theory - and, remember, Wagadu's magic knowledge must not be experimented by one person."

"I'll keep it in mind, Professor."

——

"The latter must be prioritized between offense and defense. As long as the armor spell can be resisted, the slow casting problem of the transformation spell can actually be solved."

After thinking about the magic system he mastered in the Forbidden Forest, Andrew concluded what he lacked most - protection.

Although his offensive spells are nothing, once he is given enough time to release them, even a graduate...

'No, there is no need for graduates...at least elite graduates like Percy...'

Although Professor McGonagall did not officially let him learn human transformation, he could already break through the shields of ordinary graduates and kill them.

Even if he is given some time, he can now directly transform and strangle the opponent's armor spell - but only if the opponent does not move or cancel...

'But there is no way to remove the clothes... After breaking through the iron armor curse, strangling the opponent directly does not seem elegant and magical enough, but it is actually feasible...'

"So, the Iron Armor Curse, the Iron Armor Curse..."

'I can't find Percy. Percy's Iron Armor Curse has too much magic power and I can't penetrate it... I don't know about Senior Nellie, well, if he hasn't graduated yet, let's see if I can get him, or he can recommend someone. Hufflepuff is still reliable...'

——

Garen's power has always been strong, and Senior Nellie even dedicated a weekend to cooperate with Andrew in deciphering his iron armor curse...

As for the original theory, it is even simpler - after making this somewhat willful request with his dean, Professor Flitwick happily provided it, and even included some of his insights.

The only requirement is that you must submit an experience after completion. Even if you fail, you must provide it-why you failed, what is the difference, and where did you think wrong...

It's not too much to ask - Andrew intends to memorize the whole thing anyway.

"Two days, Iron Armor Curse?"

"Of course, Senior Nellie...two days...I think it's enough to study something...Of course, it can't be done in one go. If it's possible next weekend, can you make an appointment?"

"no problem."

——

This is a completely different thought - compared to the previous Bubble Curse, this time Andrew can directly use transformation to experience the power of the so-called Iron Armor Curse.

Senior Nellie is quite proficient in the Iron Armor Curse, but compared to Percy's perverted level, it's still not good enough.

After using the transformation technique for about two minutes, Andrew successfully communicated with the power of the Iron Armor Curse and tried to use the transformation technique to control him.

"It feels like the consumption has increased, Taylor-san!"

"That's right, please hold on, senior."

Andrew began to slowly mobilize the power of the Armor Spell - it was evenly distributed on the outside of the wizard's body. It was most powerful when it just appeared, but then it began to slowly weaken until the next casting.

'According to the information given by the dean, at the moment of appearance, if someone has a comprehensive grasp of the spell, he can even use the Armor Spell to rebound the opponent's attack to cause damage. '

'But the problem now is that I can't transform the spell in the first time, even a beginner can't do it, and can only use the spell to break it directly...'

'So don't think about rebounding, but if it's offset, you can consider it...'

——

'Damn it, this kind of transformation...'

'Why do I feel that my Armor Spell is going to kill me? '

Nellie was quite nervous at the moment.

Theoretically, the Armor Spell will only give people a sense of security. If it is not enough, you can replenish it again - if it doesn't work, you can only study hard.

But at present, he only feels that his Armor Spell has completely lost control.

As for the large amount of mental consumption, let alone...

The strength of the Armor Spell is madly weakening, and there is even a feeling that it will be broken immediately.

"Snap..."

The Armor Spell was shattered.

"Please cast the spell again, Senior Nellie."

The voice of Taylor came.

The power of losing control was really uncomfortable, but after thinking about Garlon, a new Armor Spell was immediately formed.
