This is what Ravenclaw looks like.

"Huh...huh..."

On the edge of the Black Lake, Andrew changed from running to brisk walking while looking at the dense crowd beside the Black Lake and shaking his head.

It’s already November, isn’t this the time to be lazy in bed?

How come these people are more energetic than him?

Because the school did not make any official denial, the popularity of "Magical Legends" magazine in Hogwarts has not gone away, and every time a new issue is released, the popularity will increase again.

While Andrew was hard at work practicing transfiguration, other students were not idle either. An empty classroom would always attract waves of students, and Oil Painting could no longer be annoyed by the energetic new students.

Even the ghosts of the castle almost refused to show up, but they were all relieved after the latest issue of the magazine was released - because I don’t know who the rumors came from. There are various versions, but there is no one. Don’t point the finger at the magical place of Black Lake.

Some say that the inheritance of Slytherin is here, some say that the traces of the war are at the bottom of the lake, and some say that the memories extracted by Dumbledore are at the bottom of the lake - this has led to the recent confusion here from day to night. Not idle.

Andrew naturally wouldn't plan anything about the Black Lake - let alone whether there is one, even if there is, he might as well seize the time to practice his transformation technique to be sure.

But he has something to envy. At this moment, many of the senior students gathered around the lake are wearing transparent covers on their heads. After using various methods to keep warm, they can dive into the lake to look for possibilities. The treasure that exists.

'I seem to have heard of a similar spell...'

He looked at the people who had entered the water and made up his mind, ready to start looking for prostitutes from senior students - there was basically no confidentiality for magic that was so widely circulated.

"Ah, you mean the Bubble Charm?"

When Andrew found the senior student who had just finished class, the other student looked at him in surprise.

"Why do you want that magic? You don't believe that story, do you?"

"That's not true, but I think this magic might have some uses."

"Okay... maybe he can deal with some of the stuff those vendors are throwing out in a hurry?"

The other party shrugged his shoulders and said, "I don't know how to do it, but just wait a moment. I know there are people who are studying this spell."

After about five or six minutes, Andrew finally understood the magic of the Bubble Curse.

This spell is not very practical, because its effect is to create a transparent cover that covers the head, and then the wizard can move with it in places where the air is not very good.

This kind of spell is not very defensive, not offensive, and has no curse. In addition, it is not widely used. It has been widely circulated among students for a few days. The previous popularity was due to Peeves' chaos. It only became popular for a while that people had to cover their faces when throwing things.

"Occasionally, adventurers learn it - but compared to this spell, human body transformation is more convenient in harsh environments, and there are corresponding potions. Some smugglers have improved the spell, but those people are sure Just don’t let the magic leak out.”

After a brief introduction, the other party gave Andrew a parchment with spells and spell-casting gestures written on it. "Although it is a spell that can only be used by seniors, but if you want to study it, just take a look. I will graduate when you are able to cast spells." Already…”

"Completely two styles..."

Andrew looked at the magic on the note. It was too simple to be ridiculous - it didn't refer to the spell, but the related explanation.

Unlike lower grade textbooks that want to break down the spells and explain them in detail, this bubble spell seems to imply that you have the corresponding knowledge of spell casting and have enough experience in wand casting and spell maintenance.

To put it in layman's terms, using this spell requires by default the spell base level 9, the spell gesture level 7, the spell maintenance specialty, and the spell materialization level 5...

All these messy prerequisites must be learned in previous studies - only by forming instinct and inertia in the basic spells, can we rely on simple spells and gestures to cast this combination. Not simple magic.

"This is not a spell that lower grades can master - no, if someone is willing to break it apart and learn this spell like analyzing the spells learned by lower grades, then its difficulty is not that high..."

"But who would include this in the basics? As the senior said, this spell is neither representative nor derivative..."

Andrew rolled his eyes - Professor Flitwick would definitely refuse. With so many people adventuring in the Black Lake during this period, he would definitely not teach this kind of fueling spell decomposition to first-year students.

His own research is definitely in vain - although he has put some effort into the curse, he is at best an outstanding first-year student and cannot even reach the top level, let alone researching such a thing.

"But I still want to learn... Just being able to go into the water is good enough... The ability to survive accidents and extreme environments is also impressive..."

He was very familiar with the traditional life-saving skill of hiding underwater - if it took him a while to master it, it would definitely be worth it.

'Furthermore, if you learn how to do it, even if you go into the water to save someone, there will definitely be no accidents...'

Sighing, he put aside the memories in his mind and began to think quickly...

'It is too difficult to directly master the Bubble Curse, but if you use the knowledge you already have to solve it...'

What he can still use now is his understanding of transformation. 'The essence of the bubble spell is to summon a bubble that can cover oneself...and it is very tough...'

'But I can completely equate it to using a transparent glass-like cover that fits better...'

'But the difficulty of the problem is that the Bubble Curse is far more than just the air it seems. According to the principles I heard, it can be enough for a normal person to go back and forth to the bottom of the Black Lake...'

‘So it compresses the air? It's not like that, or should I say, the Bubble Curse has a filtering effect? ’

‘If it’s the former, can I consider deforming the air itself? No - it should be transformed multiple times...or using techniques to restore the gradually failing Bubble Head Charm to air without collapsing? ’

'What if it's the latter...that would be difficult...'

‘But where can I find someone who is willing to cooperate in researching the specific effects of the Bubble Head Charm? ’

‘We can’t ask Professor McGonagall...she definitely doesn’t want me to spend time on this kind of Black Lake disciplinary project. ’

‘Yes! ’

An incident occurred some time ago that suddenly came to mind - someone paid someone to look for information in the library.

Although it is difficult to find people who are friendly and helpful, there is a communication skill that is efficient and makes the other party happy.

'Ah, thank you Dumbledore...there is a way...'
