After a week's break, Harry and Ron finally went back to class.

"Harry, Quirrell is dead, who's going to take Defence Against the Dark Arts class?" Ron lay on the table, listlessly looking at the notes Hermione had put together for them. Even though she hadn't attended classes for a week, it looked like the sky was about to fall in Hermione's eyes.

"I don't know," Harry flipped through the Defence Against the Dark Arts textbook boredly, "it's unbelievable that anyone is better than Quirrell, our Defence Against the Dark Arts professor for the past few months has turned out to be Fu..."

Ron quickly motioned for Harry to stop talking, "Harry, Professor Capet won't let us tell us about the mystery man. ”

"It also makes me wonder," said a nameless fire in Harry's heart, "why is Professor Capet not allowing us to tell the truth about the matter?" ”

"Harry, the fact that the mysterious man has been lurking at Hogwarts for half a year will cause panic," Hermione closed the book, "and this matter is already nosy, if we don't go find the Philosopher's Stone, Quirrell won't be able to get through Professor Capet's mechanism." ”

Harry's face turned red when he heard this, if it weren't for his suspicion of Professor Snape, he wouldn't have let Quirrell take advantage of it, and even let Ron be hurt by Voldemort's spell.

"But I always didn't think Snape was a good guy," Harry muttered, "and he was always aimed at me. ”

"Maybe it's for another reason." Ron guessed.

Harry was about to retort a few more words when a young wizard with glasses walked in.

"This man is so strange." That was Harry's first reaction. He felt as if he had seen the man's face, but he couldn't remember where.

"Hello kids, I'm your substitute teacher for this lesson, Luigi Bourbon." The young wizard introduced himself.

The students under the podium began to talk in low voices.

"Hermione, have you heard of this teacher?" Ron asked in a low voice.

"No," Hermione shook her head, "I didn't hear of this professor in the castle. ”

"Okay, my identity is not the point, the point is that your class is about to begin." The "Bourbon" professor's voice made Harry's soul tremble, and the riot in the class was quickly suppressed.

This Luigi Bourbon was of course Calvin, and although Dumbledore had repeatedly promised that his life would not be in danger after only one or two lessons, Dumbledore's words were now a question mark for him.

In order to avoid Voldemort's curse, Calvin made ample preparations - changed his appearance and voice, used a pseudonym to attend classes, and if there was a curse, please go to Luigi Bourbon, who has nothing to do with me Calvin Capet.

"In this lesson, we need to learn how to deal with Grindy Lowe properly." Calvin said with a blank face that he had no interest in the class and just wanted to finish it quickly, "Turn the book to page 73." ”

The young wizards quickly opened the book, and only Harry was still staring at Professor Bourbon, remembering where he had seen him.

Calvin quickly pointed his wand at Harry's book, helping him turn to page 73, "Don't get distracted, Mr. Potter. In the face of dark wizards, if one is not careful, his life will be in danger. ”

"He's definitely someone in the school, he knows me." Harry lowered his voice and said quickly.

"Harry, even if you're not from school, you know you, like my sister." Ron didn't understand why Harry was so obsessed with being a substitute teacher.

"Mr. Potter, Mr. Weasley, don't talk to each other in my class," Calvin walked over to the two-man table, "let me see it one more time, and I'll deduct points." ”

Almost all of the Gryffindor and Slytherin wizards turned to look at Harry and Ron, and Harry just wanted to hide himself with the book.

Draco was a little disappointed, it seemed that the substitute teacher was biased in Harry's favor, and if Professor Snape had been in class, Gryffindor would have been deducted at least ten points.

"First question: What is Grindy Lowe?"

Hermione and Draco raised their hands at the same time, and Calvin didn't hesitate to choose - Draco.

"Malfoy, tell me about it."

Draco stood up and said quickly, "Grindillo is an aquatic dark magic creature that usually lurks in aquatic plants.

They are covered in green, with green teeth, horns on their heads, and very long fingers, which is one of their weak points. ”

'Very good, I don't have anything to add, Slytherin plus five points.' Calvin motioned for Draco to sit down.

Draco gave Harry a defiant look and pointed to his brain.

Harry was dumbfounded and asked in a low voice, "Hermione, when did Malfoy become so powerful?" ”

Hermione stared at Calvin and replied in a low voice, "His grades weren't bad in the first place, and after the holidays, I don't know what happened, and the time in the library was about the same as mine." ”

Harry and Ron only felt like they had spent a week in the school hospital and the whole world had changed.

"It's easy to deal with Grindy Lowe, don't let them catch them, and use the Withdrawal Charm." Calvin felt that he was very irritated, this class should not have been there at all, and the students should have been allowed to study on their own.

"Let's talk about this withdrawal spell without a wand, please tell me...... Loose force. ”

"Loose and energetic!" The class said in unison.

"Well," Calvin said, "well, so who wants to be the first to try Grindy Lowe?" ”

Many of the young wizards raised their hands and were eager to try, most of them were Gryffindor students.

Calvin picked out a little wizard with light brown hair and blue eyes, "You, that's it, what's your name?" ”

"Professor Bourbon, my name is Seamus, Seamus Finigan." The little wizard said excitedly.

"Yes, Mr. Finegan, please come up." Calvin gave up half of the podium, waved his wand, and conjured a water tank.

Although Seamus raised his hand without hesitation below, he still had some fear when he came up to face the constantly shaking water tank, and swallowed a mouthful of saliva.

"Don't be afraid, Mr. Finigan, I'm here." Calvin encouraged the little wizard, "Are you ready?" ”

Seamus nodded tremblingly.

"Then, I'm going to open the water tank." Calvin waved his hand, and the slate covering the water tank vanished.

Soon, a sickly green creature slowly surfaced, with a bulbous head and small short hands that looked like ugly octopus claws.

It grinned, emitting a rancid stench, dense with tiny green teeth, like a row of painted steel needles.

Seamus seemed stunned and stood still, motionless. Calvin patted him on the shoulder with his hand, "Don't be afraid, I'm here." ”

Hearing the Professor's words, Seamus seemed to muster up his courage, he raised his wand and shouted at Grindy Lowe, "Loose and strong!" ”

Only a boom was heard, the water tank exploded, and the podium was covered with dust.
