The Potions classroom was in a dark, damp attic.

Considering Hogwarts a thousand-year-old castle full of historical traces, it's not unusual to see a room filled with old wooden tables, old musty smells, and mixed herbs.

Li Quan stood in front of a teacher's test bench and looked at the old Gothic building in front of him, the walls of which were so old that several layers of paint had fallen off and were mottled like some postmodern abstract paintings. The old crucible on the table was bubbling boiling water, the only sound in the room at the moment.

At the side of the classroom, a wooden shelf was stocked with all the herbs and alchemy equipment needed recently, and there were so many types that you could make any potion you could think of here. This is what he prepared for today's class, with great support from Professor Sprout. Of course, the vast majority was left behind by Snape.

At this point, Snape did not make things difficult for him.

Li Quan closed his eyes and thought about it in his heart, confirming that all the preparations were ready. And he himself was ready. He had enough knowledge in his stomach to deal with these Hogwarts students. His combination of potions and alchemy, which even Dumbledore praised, was more than enough to teach his students. It's like an old bookworm who has read hundreds of books, and it's as easy and simple as teaching elementary school students to write Chinese characters.

He pulled out his phone and looked at the time. It's almost time, and the students should be almost there for the first class. As soon as he thought about this, he saw the first student walk in through the dome arch of the classroom. It's a little girl with long brown hair and a little shy.

As soon as Hermione came in, she immediately saw Li Quan in front of her, and she greeted Li Quan with a sweet smile very politely: "Good afternoon, Professor." ”

"Good afternoon, Hermione." Li Quan nodded with a smile and said.

Hermione was surprised, her face flushed slightly, obviously surprised that Li Quan knew her name.

Hermione sat down and took out a few books and read them carefully. The other students hadn't arrived yet. Li Quanxin said that Hermione deserved to be a top student, and there was a reason for her good grades. He didn't know that Hermione was just pretending, but her heart was pounding.

It took about five minutes for a second student to walk in. A large number of students followed, including first-year students from various faculties.

Li Quan saw Harry Potter and Ron, two inseparable best friends, also appear at the door. The two were about to come in, but Malfoy, who had blonde hair and a big back, took a step forward, squeezed Harry and Ron, and entered the classroom first to occupy a window seat, followed by Malfoy's two little fat men, who followed Malfoy's example, and also squeezed Harry and Ron at the door.

Harry and Ron dared not speak in anger, the class bell had already rang, and they saw Li Quan standing in front of the stage, so they silently hurried to the remaining two seats and sat down. Next to them sat Hermione.

When Li Quan saw that everyone had arrived, he walked down and smiled at everyone. "Let me introduce myself first, I will be your Potions teacher for the next year, my name is Li Quan, you can call me Professor Li."

"Wow, so handsome—" A few girls lowered their voices and communicated with each other, but they couldn't escape Li Quan's extraordinary ears.

These girls have obviously become a staunch supporter of his handsome professors in the East. Even Hermione looked at him with little stars in her eyes. This reminds Li Quan of the swaggering wizard star in Harry Potter's second "Chamber of Secrets", Professor Lockhart, who is also so popular with girls. But his skills are much better than Lockhart's scumbags and cowards. He's the real thing, it's just life and death, and now he has an army of plants, and he doesn't bother anyone except Dumbledore and Voldemort.

Li Quan is secretly refreshed in his heart, being pursued by so many little girls, it would be a lie to say that he didn't want to. But then there was a murmur: "Idiot." ”

Li Quan heard that it was Malfoy talking to the two little fat men next to him. When Li Quan looked at it, the three of them looked at each other triumphantly and smiled, obviously they didn't know that Li Quan's ears could even hear such a small whisper from them.

Li Quan snorted coldly in his heart, he hadn't even gone to trouble Malfoy, and this kid hit the muzzle of the gun by himself. Okay, see what I do with you.

In the original book, Snape, as a professor of Potions and the head of Slytherin House, not only favors Slytherin House, but also Malfoy everywhere, and also targets the troublesome protagonist Harry Potter at every turn. Because Snape and Harry's father were school students, they were rivals. Harry's father married Harry's mother. Snape, on the other hand, was unrequited......

In short, Snape was unhappy that Harry looked too much like his rival, and would sarcastically harass Harry whenever he had the chance. Malfoy was Harry's opponent, and naturally he was always on the smug side.

But Snape wasn't here now, teaching the coveted Defence Against the Dark Arts technique.

Malfoy, this guy dares to be arrogant in person? Li Quan sneered secretly, who gave him the courage?

Li Quan said quietly: "Okay, after introducing myself, then first of all, I hope to understand everyone's level in potions first." Next, I will ask a few questions that you can answer with your hands raised. He glanced at the students in the classroom, and they were all looking at him. The first question, name at least two aliases of Aconitum sinensis. ”

As soon as Li Quan's words fell, Hermione was immediately the first to raise her hand.

Li Quanxin said that the little girl is really cooperative, praise one. He held out his hand to Hermione and said, "Miss Granger, please, to answer my question." ”

Hermione stood up happily and began to gush on and on in reply, telling a bunch of things about Aconite. "Aconitum is the main ingredient used to concoct several complex potions, and it is indispensable. Aconitum is also known as grass black, aconite or ox flat...... "There is a lot of knowledge in it that cannot be learned in elementary potions textbooks."

"Good!" Li Quan nodded with great satisfaction and said with a smile, "Miss Granger's answer is very accurate and detailed!" Miss Granger, you may be seated. Gryffindor House plus five points! ”

Credits are very important to every college. At the end of each academic year, the four houses will evaluate the House Cup according to their scores, and the Principal Dumbledore will personally present the trophy.

Hearing that Li Quan had added five points to Gryffindor House, all the Gryffindor students in the classroom danced happily. These are children, and they are very happy to learn the meaning of credits, and they are naturally overjoyed to be added.

When Hermione heard that she had been given extra points, she immediately smiled and sat down. Harry sat next to her and whispered to her, "Congratulations, Hermione. Ron echoed his congratulations. Hermione smiled shyly and said to the two, "Thank you!" ”

Li Quan smiled faintly when he saw it, and then he asked, "Second question, please tell me the purpose of the gill sac grass." ”

As soon as the words fell, Hermione, who had just sat down, immediately hurriedly raised her hand again. The little girl has too much knowledge in her head, and this time she finally has a chance to show it.

Of course, Li Quan would not refuse to give Hermione a chance, and he smiled and said, "Then ask Miss Granger to answer this question for us." ”

"Gill sac grass is an aquatic wonder plant. When a person eats gill sac grass, fish gills grow on both sides of the face, and they can breathe in the water. It lasts about an hour......" Hermione gushed.

"Very well, Miss Granger got it right again. Gryffindor plus five more points! Li Quan said loudly.

"Yay!" The Gryffindor students couldn't help but scream, and then immediately covered their mouths and looked at Li Quan worriedly, worried about being punished by Li Quan. However, Li Quan turned a blind eye and didn't care at all. The Gryffindor students breathed a sigh of relief, and their faces beamed with joy.

Gryffindor scored ten points in a row, which made the other house students very discouraged, especially Malfoy of Slytherin House, who was even more unhappy, he looked at Harry Potter and Hermione and the others, and his arrogant expression was full of unkindness.

"The third question," Li Quan continued, "tell me what you know about the 'water of life and death'." ”

Hermione raised her hand again.

This time, not only did she raise her hand, but even Malfoy raised his hand high, and he looked at Li Quan eagerly, looking forward to answering the question.

However, as if he didn't see him, Li Quan turned his body to Hermione, completely ignoring Malfoy. Li Quan smiled a little and Hermione said, "Miss Granger, please." ”

Hermione stood up happily. "Life and death water, is a very potent sleeping pill, it needs materials such as sunlight root powder, absinthe infusion, ......"

Malfoy saw that he had obviously raised his hand, and Professor Li Quan had obviously seen it, but he didn't let him get up and answer. This is clearly targeted favoritism! It's strange that Malfoy can be cool.

He watched angrily as Hermione answered the question correctly, and was given five points by Li Quan without hesitation. "Gryffindor plus five more points."

Three points in a row made the Gryffindor students so happy that they couldn't find the north.

"It's not fair!"

Malfoy suddenly stood up and complained loudly, seeing Li Quan turning to look at him, Malfoy complained dissatisfiedly: "I also know the answer to this question, why don't you let me answer it?" He looked at Hermione, "Why do you keep letting this filthy mud ......?"

"Shut up! Mr. Malfoy. Li Quan unceremoniously interrupted Malfoy's words, and his tone was very serious, "Pay attention to your words. ”

Malfoy was startled, and Nono didn't dare to squeak, but he still had a very unconvinced look on his face.

Li Quan glanced at Malfoy lightly, walked to the table and wrote on a piece of parchment, and said, "Slytherin House, five points will be deducted for your students' unreasonable behavior in class. ”

Malfoy was immediately dumbfounded, unable to believe that Li Quan actually deducted his points. The Slytherin students all had bad faces, but no one dared to question a professor's decision. Some people think it's Malfoy's fault, and look at Malfoy with a look of unkindness.

Students from other colleges were snickering. It had only been a short time since the school started, and the students had already heard of Slytherin's bad reputation. Of the four houses, only Slytherin was almost isolated. The Slytherin students themselves are quite arrogant and reluctant to associate with other House students.

Harry and Ron were also snickering, they were so happy, they couldn't imagine that the Potions class was so interesting, and they had seen Malfoy in the first class. This Professor Li also added a full fifteen points to their college!

He inadvertently made eye contact with Li Quan, who secretly winked at Harry while the others were not paying attention. Harry received his kindness and immediately smiled at him in return.

Li Quan's serious favoritism in favor of Gryffindor can be seen even by a fool. And it seems that Li Quan is very unfriendly to Malfoy, which everyone can see. This made the Slytherins, including Malfoy, feel sorry for each Potions class in the future.

Li Quan stopped at the right time, did not continue to add more points to Gryffindor, and did not trouble Malfoy again, this time it was just a small lesson, and the future will be long. In this school, he had a way to clean up Malfoy. It's all learned from Snape.

"Turn your Magic Potions and Potions to page eight......" Li Quan began to give a formal lecture.

Everything went smoothly.

Li Quan's lesson mainly explained the characteristics and uses of the herb Aconitum in the refining of potions. Aconitum is a very common plant that is also found in nature. But this refers to the use of aconitum by shamans, which is a breed bred by shamans, and is very different from ordinary aconitum.

Li Quan used aconitum in class to make a pot of developing potion with several other herbs. It's a magic potion used to make photos move. His in-depth explanation of the configuration techniques made the little wizards feel like they were enlightened, and even a fool like Ron learned it. And Hermione had already been fascinated by Li Quan's erudition.

After class, when Malfoy walked to the door, he whispered to his two attendants in annoyance, "I'm going to go to my dad and ask him to go to the Ministry of Magic to sue Professor Li, this kind of favoritism is not worthy of being a teacher......"

Li Quan was far away and heard it clearly. A disdainful sneer crossed his lips, and he didn't care at all.

His favoritism in favor of Gryffindor was a trivial matter, and no one would bother him for this. It didn't matter at all, and even Dumbledore wouldn't bother about it.

Malfoy's little bit of a calculus he didn't even pay attention to. If his father, Lucius Malfoy, was really shy enough to stir up the situation, I believe Dumbledore would not sit idly by. He had been hired by Dumbledore himself. Hogwarts also seems to have a tradition of accepting problematic teachers.

Let's take a look at who the professors Dumbledore hired were:

Snape, former Death Eater.

Hagrid, a half-blood giant.

Quirrell, Two-Face.

Lockhart, the liar.

Lupin, werewolf.

Frenze, Centaurs.

Mad-Eye Moody, Fake ......

By the way, there's also a divination professor, Trelawney, who is mentally ill most of the time.

I won't talk about the rest. There don't seem to be a few teachers in Hogwarts who are normal. He's pretty normal in this, except for the fact that he's from another world.

Harry Potter packed up his books and cauldrons, and was about to go out, when he heard Li Quan calling him behind him: "Harry, you stay." Li Quan walked over to Harry as he looked at him quizzically.
