Although these little wizards are all casting this spell for the first time, fortunately, this magic is not difficult to learn, and nearly forty percent of the students have successfully released this spell!

For a while, a large number of buttons, flavored beans, candy bags and other small objects were smashed towards Peeves.

Peeves let out a shrill scream in fright, and quickly slipped into a pair of armor at the end of the hallway, never daring to come out again...

The young wizards laughed out loud at Peeves' hasty escape, and the corridor was filled with a sense of joy...

At this time, Lupin turned his head to look at everyone, and there was a slight smile on his face. "Everyone who managed to cast the spell just now raised their hands, let me see who has learned this little magic?"

Hermione raised her hand high, Harry was only one step slower than her, and in addition to the two of them, three Gryffindor young wizards raised their hands.

As for Ivan, of course, this magic was no exception, and this magic was a breeze for him.

"Excellent! There are six of you, and I'm going to add five points to each of you for your excellent performance! Lupin applauded and applauded, and then did not forget to comfort the young wizards who had not succeeded in casting the spell, patiently explaining to them the techniques of using this magic.

In just a few minutes, the little wizards who were still questioning Lupin's abilities had all changed their minds and had a great impression of him!

Ivan watched that Lupin could easily win the favor of these little wizards, and he was somewhat emotional, if Lupin was not a werewolf, he would definitely be able to mix very well in the wizarding world...

"Alright, let's go inside!" Lupin opened the door to the faculty lounge and smiled mysteriously. "Dealing with Peeves is just an appetizer for this lesson, you have to be mentally prepared!"

Harry and the others were nervous and expectant, and followed Lupin into the door.

"I can accept the rest, I hope it's not a spider!" Ron whispered to Ivan.

"Not necessarily, I heard that there is an eight-eyed giant spider the size of a car in the Forbidden Forest, maybe Professor Lupin will catch it and let us see the world!" Ivan said teasingly, and Ron was so frightened that his face turned blue...

Of course, Ivan knew that Lupin's lesson would allow them to deal with Boggart, but for Ron, it was no different from dealing with the big spider, so he asked him to prepare mentally in advance.

Walking into the long classroom, Ivan glanced around, the interior of the classroom looked a little old, the walls around it were lined with wooden panels, and the room was full of old chairs that didn't match.

Lupin's wand flicked on his wand, and the tables and chairs were swept to the corners, freeing up a large open space, and then he was about to swing his wand to close the door.

At this moment, a gloomy voice came.

"Don't close the door, Lupin! I think it's better not to witness your terrible teaching methods..."

Lupin raised an eyebrow and stopped what he was doing.

Ivan heard the sound of the voice, and Snape was walking from the right, clutching a reagent bottle.

Ron and the others were very angry by Snape's words, after experiencing the previous Peeves, their senses for Lupin were quite good,

Harry retorted even more angrily.

"We all think that Professor Lupin teaches well, at least better than..."

"Shut up, Potter!" Snape interrupted Harry's next words, staring at him like eagles, "Wantonly insulting a professor, Gryffindor deducts thirty points!" ”

Harry's eyes widened, and the rest of the Gryffindor cubs glared at Snape, who would have been in a state of scars if his eyes had killed anyone.

They knew that Snape must have heard what Professor Lupin was saying to them outside the door, because Lupin had just given them thirty points earlier.

"Severus, it's me in class right now!" Professor Lupin frowned, accentuated his tone, and reminded aloud.

But just as Lupin was about to say something again, Snape revealed the dark brown potion in his hand, and deliberately dangled in the air for a moment before handing it to Lupin and speaking.

"This is your medicine, I've already made it in advance, so don't bother me when the time comes!"

Lupin faintly felt that something was wrong, but he still took it silently, put it away as soon as possible, and Snape didn't stay long, and walked away.

"Alright... Let's forget about this little episode and move on to the lesson! Lupin watched as the young wizards shifted the subject, and then continued.

"And I've just decided to add an extra 30 points to the one who did the best this time! So you're going to have to work hard! ”

After Lupin's words fell, the sound of heavy door slamming from behind could be heard, and Harry and the others laughed heartily, and even if they didn't look back, they could guess that Snape must have looked bad when he closed the door.

Lupin also smiled along with everyone, but the smile on his face gradually disappeared after his eyes were fixed on Ivan.

He suddenly realized why Snape had given him the Wolf Poison Potion at this time.

Because Ivan, as the developer of the wolf poison potion, can definitely recognize what this potion is, so as to guess his identity.

Thinking of this, Lupin felt uneasy in his heart, and froze in place for a long time without moving, which made the little wizards very strange.

At this time, Ivan, who seemed to be chatting with Hermione, turned his head, looked at Lupin, who had been stunned for a long time, strangely, and said aloud.

"Professor Lupin, what's wrong? Don't we have classes? ”

"Oh no, nothing!" Lupin reacted quickly, observing Ivan's expression and breathing a sigh of relief after noticing anything unusual. He thought Ivan was supposed to be talking to Miss Granger and hadn't noticed the potion.

What Lupin didn't know, however, was that Ivan had deliberately pretended to do so.

When he saw Snape take out the vial of wolf poison, Ivan guessed that Snape was trying to get rid of Lupin by using himself as the "Defence Against the Dark Arts Teach Killer".

After all, Dumbledore should have asked Snape to promise not to reveal the identity of Lupin's werewolf, but with Snape's dislike of Lupin, it was inevitable to engage in small actions in private.

Snape introduced the habits of werewolves and how to identify a werewolf to Harry and others during a short substitute lesson, hoping that a student would be smart enough to take the initiative to discover Lupin's identity.

This time, it caught his attention...

It's a pity that Snape probably didn't expect that he already knew the identity of Lupin's werewolf wizard, and Ivan didn't mean to deal with Lupin, in addition to the identity of a werewolf, Lupin was still very qualified as a professor.
