Hogwarts: What are the four great masters doing?

"Of course, Professor."

Ryan nodded naturally after hearing this. "Of course I'm willing to help you. Of course—I don't think you don't have teaching experience... In fact, I heard that most of the Aurors of the previous generation were considered half of your apprentices. They all spoke highly of you and called you a pioneer of justice."

No matter what he thought in his heart, Ryan was always generous in praising him on the surface.

But after hearing his words, old Batty just smiled without comment.

"justice..."

He murmured the word.

"All right, Winky—go back to where you belong."

Then he turned and gave an order to the house-elf.

"Yes, Master."

So, Shanshan bowed and answered.

Then it snapped its fingers lightly, and the office door opened by itself.

Then a shining figure flew into it and soon disappeared.

Then the office door closed again.

"Take a seat, Elias."

Old Batty said this, then walked to the podium and closed his eyes to rest.

Ryan didn't say much, but just found a seat and sat down quietly.

Soon, other little wizards arrived.

After seeing old Batty with a serious face and eyes closed, even the little lions who were used to being noisy did not dare to speak and sat down silently in the classroom.

And after all the little wizards were seated.

"I've heard about your classes in recent years—Professor Marchbank told me, and I think you've heard of her. She's in charge of assessing your OWLs and NEWTs."

"When I decided to come to Hogwarts to teach Defense Against the Dark Arts, she once said that your foundation was not solid and hoped that I would strengthen your foundation and not say anything too cruel."

Old Batty spoke.

He was not as taciturn as usual, but instead seemed very talkative.

Then he looked at the little wizards below who were in complete silence.

"That's right—cruel. This is the first word I'm going to teach you."

"Dark magic is cruel, dark wizards are cruel, and fighting against dark magic is cruel...it always means death!"

He opened his hands.

At this moment, he didn't seem to be teaching the young wizards, but rather giving an impassioned speech before the war.

"I don't want to deceive you, but this is the truth - Cornelius always says everything is peaceful, everything is going well, that the war is over."

"But the truth is... the war never stops, the dark wizards are always there!"

"I spent my life fighting them, I sacrificed everything, and I never regretted it."

"But I'm old, and you..."

He looked at the little wizards in front of him.

"You are still young, you are the future - you are the ones who will fight against the Dark wizards, or you may become them."

"So I came here... not to play house with you, but to truly teach you and guide you so that you don't go down the wrong path!"

"That's what Defense Against the Dark Arts is all about, and I'll show you."

When he said this, the little lions all looked happy.

Especially those like Harry and Neville who have a feud with dark wizards, their faces turned red at this moment.

At this moment, even Ryan couldn't help but be moved.

Because he could hear the sincerity in old Batty's words...and the pain that was hard to hide.

This reminded Ryan of the experience of Barty Crouch Sr.

As he said, he did spend his entire life fighting against dark wizards and gave almost everything for it.

He spent his youth and prime years fighting against dark wizards, and his son and wife both left him in the course of time.

Ryan thought it was easy to understand the pain in old Batty's words at this moment.

His son, and his only blemish, Barty Crouch Sr.

This Death Eater of Voldemort was undoubtedly a talented wizard.

He is extremely talented and intelligent, and excels in school.

No matter how you look at it, he should be the successor of old Batty and become the backbone of the fight against evil.

But the fact was, he became a Death Eater - all the talents he had shown in the past seemed disgusting at that time.

And Ryan certainly understood.

The reason why Barty Crouch Jr. eventually became a Death Eater must have something to do with Barty Sr. - perhaps the latter was too busy to take care of his son, or there were other reasons.

But in short...old Batty must have regretted this for the rest of his life.

But no doubt.

Apart from this blemish at this moment.

When it comes to fighting against dark wizards, old Barty Crouch is indeed a real and most respectable fighter.

At this moment, Ryan roughly understood why old Barty was so popular in the Ministry of Magic - especially among the Department of Magical Law Enforcement and the Aurors, his reputation was even no less than that of Dumbledore.

What is happening now is the answer - no one with a sense of justice would not appreciate such a leader.

For example, Harry and Neville, Ryan felt that if they became Aurors after graduation and then met a boss like old Barty, they would definitely admire each other very much.

Of course.

The agreement and admiration for what old Batty said at this moment could not dispel Ryan's doubts about him.

"Well, now... let's start the class."

After finishing those words that sounded like a pre-war mobilization, old Batty regained his composure.

"Put down your textbooks—they don't have what I want to teach you."

"Next, keep your eyes open... Mr. Elias, please step forward."

He said so.

So Ryan naturally stepped forward.

Old Barty took out a bottle containing black magic power.

Then...

"Mr. Elias, do you recognize the spell represented by the magic power inside?"

he asked.

After these words were spoken, most of the little lions were naturally confused - their knowledge of Defense Against the Dark Arts class obviously did not allow them to reach the level of being able to identify the type of spell through magic.

But Harry, Hermione and others were not surprised - Ryan had already explained to them about the configuration of spells.

"...a powerful corrosive spell?"

Ryan only took a glance and saw the spell in the bottle.

"Yes, a very strong corrosive spell—it requires a corresponding counter-spell to break."

Old Batty nodded.

"This is what you learn in textbooks, but...it's actually much more complicated than that."

"I'll show you its power with your own eyes - Elias."

He said to Ryan, "Of course you know the counter-spell?"

"of course."

Ryan nodded, but for a moment he was not sure what old Batty was going to do.

Cast a counter-spell, break the spell - it doesn't seem that easy.

And the next moment, old Batty's words confirmed his guess.

"I will let the spell within this ball of magic work on me, and then... I will break it with a counter-spell."

"And you—Elias, I want you to watch. If I fail to cast the spell in time, you will help me cast the counter-spell..."

He said so, and Ryan naturally looked at old Batty in surprise after hearing it.

"Let it work for you?"

He almost suspected that he had heard wrongly.

But before he could say anything.

The next moment, old Batty was waving his wand.

then...

"Buzz!"

The magic power in the glass bottle suddenly flew out the next moment!

They let out a series of sharp whistling sounds, and then... they flew onto old Batty's arm.

Then...

"laugh!"

Accompanied by a creepy, piercing sound.

All the young wizards saw that old Barty's arm began to rot at a speed visible to the naked eye.

His flesh began to twist and shrivel, his blood turned black, and his skin began to crack and form holes.

People could even see the hideous bones beneath his hollow skin.
