Potion is one of several compulsory courses, and it has always been a big course that needs to be combined by two colleges.

Today, the potions classes at Gryffindor college and Slytherin college are scheduled for class 3 and 4 in the morning. When everyone had just finished their last class and was rushing to the potion class classroom in the basement, the students of the classmate's college were talking to each other.

The other students knew a little later than Harry and them, but it didn't take long. When the breakfast time was over, the notice about the adjustment of the professor was posted on the notice board in the lobby and the public lounge of the four colleges.

To tell you the truth, this announcement is not just the news of changing a professor. When the little wizards learned that, both Gryffindor and Slytherin were in a complicated mood.

The whole Hogwarts knows that Snape, as the dean of Slytherin college, is not generally biased towards his college students. In addition to the bias of the teaching itself, the reward and punishment are all for the benefit of the little snakes, and the most unlucky are the little lions.

This has not changed since Snape became a professor, and there is a clear trend to intensify in recent years, mainly after Harry's admission.

But now, just today, the professor of potion class has finally changed!

Normally, this change is very gratifying. Except Slytherin, the other three colleges will cheer for it and celebrate the arrival of the new potion class.

However, although there are happy people, they are all acute people who have not read the announcement carefully. None of the students who really read the announcement can laugh.

Because Snape went to teach defense against the dark arts!

At present, the fifth graders of Gryffindor and Slytherin are still dragging their way to the potion classroom.

Gryffindors were happy and depressed, because the next potion class didn't have to stir the crucible in Snape's gloomy face. Unfortunately, the afternoon defense against the dark arts class should be careful.

The Slytherins were both depressed and happy because their respected professor snape was going to teach them some real defense spells... Well, maybe?

As I said just now, the magic potion classroom is in the basement of the main castle - this is a corridor without other entrances. The two colleges are bound to meet each other when they go down the stairs.

So the little lions and the little snakes immediately stared at each other in the slightly dark corridor in the basement, and neither side gave in. However, Draco, who has always been the main firepower, has not made any provocative moves this time, which can't help but make both sides a little angry.

Although Draco's level of ridicule has been declining in the past two years, which has affected the overall level of Slytherin college, it's not as if he's hanging his eyes and saying nothing like now?

"Draco, what's the matter with you?" the girl next to him was pansy Parkinson. She looked confused. "Although your godfather is not a professor of potions, he has changed to a better defense against the dark arts class? Shouldn't you be happy?"

But Draco just shook his head, and the tip of his golden hair swayed gently in front of him, covering less than half of his sight, so that people could not see his eyes at the moment.

A moment later, as soon as they entered the classroom, they saw a scene that they would never see in the potion class in the past.

The neatly arranged rectangular desks disappeared, replaced by round magic medicine preparation tables. The chairs in the classroom have basically been removed, and only a row of writing desks are left at the back.

After all, it is the classroom of potion class. It still seems a little dark here, because the preparation process of some potions needs to eliminate the interference of excess light. But the original brick walls were hung with exquisite tapestries for decoration. Several magical portraits from the famous potion master have brought considerable vitality and vitality to this place.

This magic potion classroom is not as lifeless as before!

What is worth mentioning is that the new professor got a lot of fluorescent white mulleins from nowhere and planted them on the surrounding ledges one by one. The little light particles floating from the stamens replaced the original low light magic lamp, setting off a somewhat mysterious feeling for the whole professor.

"Children, come in! Come in quickly!" Slughorn put on a friendly posture and greeted the students coming in with a smile, "In groups of four or five, you can choose the round table you like... Yes, just stand. The reason I'll say later... What? Three? It's also OK. I think I'd better put enough preparation tables..."

The first impression of this new class is quite fresh. Of course, in addition to the freshness, the satisfactory degree of freedom also creates a very good mood for everyone.

In fact, both Gryffindor and Slytherin have the same view on this point. However, most of the little lions show it with laughter, while the little snakes press their happiness at the bottom of their hearts, but on the surface, they show a look of "barely qualified".

"Well, students, I'm sure you've seen the announcement on the bulletin board. Yes, I'm your new potion Professor, Horace Slughorn."

The old man took out his wand and waved it. His name immediately appeared on the blackboard behind him. The font is the same as his character. It's gorgeous, but it's also witty. It's exquisite fancy characters.

After that, he smiled, nodded to everyone and continued: "first of all, I have to explain the problem of chairs for everyone, otherwise young gentlemen and ladies will probably complain about me behind my back..."

Slughorn paused a little, for some of Gryffindor's students laughed softly. They all felt that the old man seemed very talkative, and in fact he was.

"... in fact," he continued, "we know that the preparation process of magic potions is complicated. When we need to stay near the crucible to adjust and stir, it will always make people feel overwhelmed, because some guys like to create some preparation techniques with very tight steps."

At this point, he smiled and shrugged.

"So, when we are with the crucible, we basically don't want to have time to sit down. Believe me, it's really hard, especially when you don't pay attention to exercise!"

"That's why, in order for us to have more foot strength, I have to let you stand with me in class." Slughorn turned his mouth and made an innocent expression. "Yes, I have to stand too - look, let's stand together!"

Before the words fell, many students laughed secretly. For a time, the atmosphere in the classroom became more and more harmonious.

"Professor!" a Gryffindor girl student suddenly said, "did you decorate the flowers in the classroom? They look so beautiful!"

Slughorn only shook his head slightly when he heard the speech, and the smile on his face seemed mysterious.

"You'll soon know who set it up," he said. "Now let's invite the special guest of this class, Mr. Marca McLean, the youngest professor in Hogwarts!"

As this sentence sounded, a figure who could not be called tall came in from the door, but his appearance was exciting.

Not to mention that Maka's level of magic medicine is also superb. Recent events have made him more and more famous in the magic world. For these young wizards who are still chasing stars, such a celebrity who watched him step by step to the top makes them more excited than other famous wizards.

"If the white Ruihua bushes I decorated in the classroom can be liked by everyone, it would be great." Maka blinked, then walked to the front of the classroom and stood still, "but in fact, they also have tasks today..."

He pointed to the fluorescent white Mullein flowers and simply explained: "since the student mentioned them first, I'll say one more thing in advance - the brilliance of fluorescent white Mullein flowers can make the reaction process more stable when preparing vitality tonic. At that time, you can stir aliot leaves from capacity."

"It's really a professor McLean who amazed the whole European magic world," Slughorn timely held him. "Look! Just arrived, he introduced you to a new preparation technique! I'll explain first. There's no such little knowledge in the book!"

Then he suddenly turned around, stretched out his wand and pointed to the blackboard. Suddenly, the name originally appeared on the blackboard quietly disappeared, and then a line of letters appeared.

"Today we are going to talk about the last magic medicine that must be learned this semester. It is called 'vitality tonic'. As its name says, it is a medicine that can supplement and enhance the vitality of drinkers. At the same time, it is also a very practical medicine..."

At this time, Slughorn gave up his initial easygoing and his tone became serious. It can be seen that although he has some people, he has enough piety in his professional field.

Marca stood sideways and watched the bald old man concentrate on telling specific courses. She could not help but see a shadow similar to Dumbledore.

Dumbledore also started as a professor and took office at the same time as Slughorn. Maybe Albus Dumbledore was like him, standing in front of the blackboard and seriously teaching all kinds of knowledge of deformation to the little wizards in a classroom?

"... it's true that I could be the dean of Slytherin college at the beginning." Maka sighed secretly.
