Hogwarts: What are the four great masters doing?

"Ahhhh!"

So the timid little witches screamed almost instantly.

Even those who are brave or have seen the world - such as little wizards like Harry.

His face was equally pale.

What’s even more terrifying is that the corrosion is still spreading on old Batty’s arm.

At first, the corrosion was concentrated on the forearm.

But in less than ten seconds, the corrosion spread from the forearm to near the elbow.

"..."

At this moment, even old Batty's face was almost pale.

Big drops of sweat were dripping from his head and his face was frighteningly pale.

He gritted his teeth and stretched out his wand - and his almost uncontrollable, nervous and trembling movements made all the young wizards imagine the extent of pain that old Barty was enduring at the moment.

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

He slightly grasped the wand in his sleeve, ready to strike at any time.

But at this moment...

He saw that Batty was in pain, but he still recited the spell firmly.

"Sanaflora...Repurgo (Corrosion...Healing)"

He chanted the spell, and everyone saw that the hideous corrosion on his arm began to fade away the moment the spell fell.

After just a moment, the hideous scars of corrosion completely disappeared.

But old Batty's face was still pale - he could hardly stand, leaning against the desk beside him, and his usually straight spine became bent.

But at this moment...

Ryan gently supported him.

And as he supported old Batty.

The old wizard's complexion also quickly turned red at a speed visible to the naked eye.

So, Barty Crouch Sr. looked at Ryan.

"Strong willpower, Professor."

Ryan looked at him with a look of solemn admiration.

That's right.

Ryan was well aware of the effects of the powerful corrosive spell.

This spell is extremely vicious, and the pain it brings is probably only inferior to the heart-piercing and bone-drilling pain among all spells.

Even the toughest man would find it difficult to complete the spell under normal circumstances while enduring this level of pain.

But old Batty managed to do it.

This willpower deserves Ryan's respect.

"Thank you..."

Old Batty murmured and responded softly.

"No need to thank me, Professor—but I must warn you that this is very risky... As a professor, you should probably try a different teaching aid."

Ryan said softly.

"That's because you're in this class, Elias—if you weren't, I would have used a weaker spell."

This is how old Batty responded.

And after such a brief exchange, Ryan let go of his hand.

At this moment, old Batty has fully recovered.

He straightened his back again and looked up at the little wizards in front of him, all of whom had frightened expressions.

"What you just saw is a type of dark magic—as Elias said, a powerful corrosive spell."

"You should have seen that the lethality of this spell itself may not be very strong. It is far less powerful than being torn into pieces or even knocking people unconscious."

"But its characteristics are corrosive and intense pain—it affects your emotions, clouding your judgment, and rendering you unable to resist... This spell was created with this evil purpose in mind!"

"This is also the most evil part of black magic. When you fight against it, memorizing the counter-spells and countermeasures in the textbook is only the first step."

"What truly matters most in fighting against dark wizards...is strong willpower and calm judgment."

"Believe me, when you encounter a truly dangerous enemy... even the slightest loss of composure can cost you your life!"

Having said that, it seems that the little wizards seem to be keeping silent.

Old Batty's words softened.

"Of course, this spell also has a targeted defensive spell—the Purification Spell... You need to use it when you judge that the enemy will use the Corrosion Spell, and this involves considering the possible actions of the dark wizards before the spell is cast."

"Mr. Elias, could you please..."

Looking at old Barty who was gradually getting into the mood, he began to explain in a simple and easy-to-understand way, combining his life-long experience in fighting against dark wizards.

Ryan finally made the same judgment as Dumbledore in his heart.

"He may have done something for his son, but he certainly didn't join Voldemort."

Chapter 166: The Blood Queen's Research Manuscript! Apprentices and Speculations!

The first Defense Against the Dark Arts class of this semester ended.

Ryan can be sure that there is nothing wrong with old Batty.

With the willpower he showed in the Defense Against the Dark Arts class to fight against dark magic.

He certainly didn't succumb to Voldemort.

However, some of his obviously abnormal and special behaviors and attitudes indicate that he may have done something for his son Barty Crouch Jr.

This is also the focus of Ryan's next investigation.

But other than that...

"He would definitely make a good Defense Against the Dark Arts professor."

Ryan could be sure of that.

There is no doubt that old Barty's first class was extremely shocking - it is almost impossible for a Defense Against the Dark Arts professor to be willing to allow a powerful corrosive spell to erode himself in order to teach a young wizard.

And from what Ryan saw today, he was sure that every little lion was listening to the class very attentively after seeing such a horrific scene.

Ryan was sure that if old Barty could continue to teach the Defense Against the Dark Arts course, the young wizards would definitely be much better at dealing with dark magic when they graduated.

Of course, as a price to pay, I believe there will be many more young wizards applying to become Aurors as a profession.

But when he thought of this, Ryan naturally thought of another professor of Defense Against the Dark Arts.

"I wonder how good Professor Lockhart's teaching is?"

he muttered.

Indeed, considering the level of spells Lockhart demonstrated in his novels, this professor's level is certainly not inferior to that of old Barty.

But after meeting this great writer in Diagon Alley.

Ryan now had a very strange feeling about him - he always felt that there seemed to be something strange about this great writer.

"We'll find out next week."

Ultimately, that's all Ryan judged.

After finishing the Defense Against the Dark Arts class, Ryan's classes this morning also ended.

However, he did not choose to return to the dormitory, but went to the Potions office in the cellar.

"Potions are mysterious."

Ryan opened the door of the Bat's Nest with familiarity and strode in, calling out, "Professor Snape, are you there? Can you hear me?"

That's right.

"I'm afraid even the Dementors in Azkaban could hear you, Elias—even though they have no ears."

But just a moment later, the sound of bats hissing came from deep in the bat nest.

"Oh, you're still so interesting to talk about. You... wow, what did you do?"

Ryan felt a warm welcome from Snape's familiar sarcasm, but then he was stunned by the professor's new look.

At this moment, Snape was still wearing his black wizard robe that had not changed for a year and fluttered like bat wings.

But at this moment, his face was extremely thin and pale.

The hair that the young wizards had secretly muttered "maybe won't be washed once a year" was stuck to his forehead like the dead tentacles of an octopus.

Snape said nothing when he heard this.

He just glanced at Ryan, then raised his hand, stretched out his wand and waved it lightly behind him.

The next moment, Ryan saw a box flying out.

The box opened automatically in the air, and a potion bottle flew out of it.

The potion bottle flew into Ryan's hands, and the latter took it in confusion.

Then, he saw the potion flowing from the bottle.

The potion emitted a light white color, like a beautiful Madonna lily.

There were tiny specks of light flowing in the potion, like a soul.

Ryan then widened his eyes in disbelief.

"Are you done?"

He looked at Snape.
