hp: D on the left and G on the right, am I the savior?

"You are friends of George and Fred, right? I see you guys hanging out together often."

Jeffrey Glenn spoke first.

"Yes"

Suning and William both nodded.

"Why didn't I see them? I was wondering how noisy those two little guys would be when Charlie was dueling."

"They went to see Professor McGonagall. There's something..."

Jeffrey Glenn nodded as if to say "I see"

What good can come of the little lions going to their dean? Most likely they will get into trouble.

Professor McGonagall: Although, you still understand me, little Geoffrey......

"Senior David, what is that large-scale magic? Is it like the fire dragon just now?"

William was confused, and seeing his familiar senior here, he couldn't help but ask.

"Large-scale magic?"

David Eric frowned slightly and fell into a brief contemplation.

He stroked his chin gently

After a while, he slowly said:

"Large-scale magic, as the name suggests, is magic that has powerful effects and cannot be easily performed by an individual. Such magic often requires the cooperation of multiple people to complete, or requires the help of specific environments and conditions to realize its power."

He paused and then said:

"According to the records of the history of magic, the first major magic created was the 'Multiple Binding Curses'. It was a long time ago, when a group of brave and fearless wizards faced a huge challenge - how to capture a ferocious Norwegian Ridgeback dragon."

"The Norwegian Ridgeback is huge, with silver-grey-blue scales, long pointed horns, a jet-black ridge on its back, and no spikes on its tail. This dragon is extremely aggressive and will attack most types of large land mammals, even animals in the water."

"And it contains many precious materials."

"Killing a Norwegian Ridgeback is easy, but capturing it is the most difficult. Especially if you want to ensure that the Norwegian Ridgeback does not get hurt."

"This dragon has great strength and agility, and ordinary magic cannot subdue it at all. So the wizards came up with a brilliant idea. They need eight wizards to work together and cast a binding spell on the Norwegian Ridgeback at the same time. In this way, even if a single binding spell is strong enough, through the joint efforts of multiple wizards, it can ensure that the target is firmly bound and cannot escape."

At this point, David Eric's eyes became more profound, as if he had traveled through time and space and returned to that legendary era. He continued:

"The principle of this magic is actually very simple. It is to use collective power to bring together the magic of multiple wizards to form a powerful binding force. This power far exceeds the limit that a single wizard can exert, making it impossible for the Norwegian Ridgeback to break free. Of course, in order to successfully perform this magic, it also requires a high degree of tacit cooperation between the eight wizards and a precise grasp of the timing. Only when they cast the binding spell at the same time can the greatest effect be achieved."

Suning listened to David Eric's introduction and gained a deeper understanding of the application of magic.

Seeing David Eric suddenly stop, knowing that he had fallen into his old habit (easily immersed in the story), Jeffrey Glenn reluctantly took over the conversation and continued to popularize science for the younger students:

"The successful capture of the dragon allowed wizards to see the possibility of large-scale magic"

"Since then, large-scale magic has appeared like a gusher, such as joint protection spells, combined attack spells, large-scale summoning spells, and even special rituals."

David Eric came back to his senses and immediately continued:

"Yes, that's why. In just a few years, wizards began to walk out of the laboratories. In order to obtain materials or perform certain strict rituals, they began to actively unite. As a result, the connection between wizards became deeper and deeper."

“It’s like a revolution, bringing together isolated individuals into a powerful force. This transformation not only changes the way wizards live, but also has a profound impact on the entire wizarding world.”

"There is even a group of wizards who have begun to give up personal magic and focus on large-scale magic. They claim that large-scale magic is another option for wizards and the wizarding world."

“These brave ‘pioneers’ rejected traditional individual magic in pursuit of a larger, more influential force. They believed that through collective wisdom and effort, they could create magic greater than any individual could.”

“At that time, this group of people was very popular because the large-scale magic they mastered was indeed powerful. People were full of curiosity and expectations about this new form of magic, and these wizards lived up to expectations and demonstrated amazing magical powers. Their existence made people see the unlimited possibilities of the wizarding world and opened up a brand new path for future development.”

"However, this seems to be nothing more than the wizards' wishful thinking."

"Because soon, an unavoidable question arose: what would happen if large-scale magic was used in war?"

Suning swallowed his saliva, imagining what he would do if he encountered magic like "Dance of the Fire Dragon"...

William sat up straighter, his mind already attracted by the events described by David Eric.

If only the History of Magic were this exciting...

This thought flashed through William's mind.

Jeffrey Glenn coughed lightly, signaling David Eric not to talk about such a cruel thing as war in front of the little wizards.

David Eric smiled lightly:

"There is no shortage of ambitious people in any era, which led to the wizarding world at that time experiencing several brutal wars and betrayals."

"After the war, the wizarding world realized one thing"

He said quietly:

"Major magic is a wand that can cast magic at both ends, and human nature is its magic. No one can predict which end of the wand will cast magic."

"So, the Ministry of Magic at that time began to strictly prohibit the use of large-scale magic. If large-scale magic had to be used in some special occasions, permission from the Ministry of Magic had to be obtained before each use, and the Ministry of Magic had to monitor it."

"So, due to the restrictions on the use of large-scale magic, coupled with the high cost of practicing it, it gradually faded out of people's sight."

Suning continued to digest everything David said. At this moment, he was clearly aware of the wizard's vitality.

Wizards are also human beings, and the wizarding world has its own history.

This is not a plot from a storybook, but a record in the history of magic.

In the pursuit of power, there are always people who will continue to take the lead.

Large-scale magic may be a legacy of that period of history.
