Professor of Pharmacy at Hogwarts

The next day, Sunday.

The failure to win Quirrell in one go made Alexis a little frustrated, but more importantly, it made him wake up and realize that this was not a fairy tale, and what he was facing was a real person.

Alexis was honest on Sunday. He didn't hang around or cause trouble. He stayed in his office and did research all day.

This made Dumbledore, who was observing quietly, relax.

It looked like Alexis' behavior last night was just intermittent convulsions.

However, only Quirrell and Alexis knew that Alexis was more wary of Quirrell.He had been watching Quirrell all day.

The peaceful Sunday passed quickly, and the next day was Monday.

The weather on Monday was not very good, and it was a bit gloomy. When the students had breakfast and started classes, it even started to rain.

Alexis's pharmacy elective class starts at ten o'clock, and the first class is for third grade students.

Almost all the stairs in the main building of Hogwarts have changed. If you want to remember these changes, you can find the way to the next classroom in just 10 minutes between classes. For first-year students who have just arrived for a week, Said it was a severe test.

Not to mention freshmen, even many upperclassmen often take the wrong path.

Fortunately, Alexis had spent seven years at Hogwarts and knew the place well enough. When he walked into the classroom, there were only a few people sitting in the Potions class room.

Alexis ignored the whispers of the students below. He took out the roster and browsed it briefly, nodding with satisfaction.

This class was for the third grade. There were a total of twenty students from Slytherin, Gryffindor and Garvinclaw, and the number of students from his "hometown" Hufflepuff reached a terrifying 33!

This is almost the entire number of people in Hufflepuff's entire third year.

Alexis didn't know whether it was organized by the little badgers on their own or under the instruction of the dean. Either way, he was very moved.

Students entered the classroom one after another, and were still talking and laughing loudly in the corridor. After entering the classroom and seeing Alexis standing in front of them, the students stuck out their tongues, lowered their voices, quickly found their seats, and behaved obediently. Sit down, take out a book to block Alexis' view, and communicate in a low voice below.

The whole classroom immediately became buzzing, as if facing millions of flies.

Students entered the classroom one after another and the empty seats were quickly filled.Alexis glanced around and counted silently.

53 people, just right!

clap clap!

Alexis clapped his hands, and the whole classroom fell silent. The students raised their heads and looked at Alexis in front of them.

"My name is Alexis Felix," Alexis glanced around the classroom and introduced himself with a smile. "You can call me Alexis, or Mr. Felix, whatever."

"You are third-year students, so I don't need to emphasize classroom discipline. I hope we can spend a pleasant two hours together. Okay, let's start class."

Alexis smiled slightly, walked back to the podium, listened to the sound of turning books below, and asked aloud

"Do you know anything about plant taxonomy in the Muggle world?"

The little wizards stopped what they were doing and looked at Alexis.

"Do you know? This question is worth one point."

There was silence in the classroom.

"Three points."

Little wizards, you look at me and I look at you, a little moved.

"Five points!"

Alexis ups the score again.

There was a slight noise in the classroom, and the little wizards couldn't help but discuss in low voices.

Alexis did not maintain classroom discipline, but quietly waited for the results of the students' discussion.

Soon, the classroom became quiet again, and everyone looked at Alexis again.

"It seems that no one knows." Alexis was a little disappointed. "The Muggle world roughly divides plants into ferns, mosses, gymnosperms, and angiosperms."

"According to their different classifications, they are further divided into six levels, namely phylum, class, order, family, genus, and species, systematically covering all plants. Plants under the same level and genus have the same characteristics, so that Whenever we encounter a newly discovered plant, we can quickly incorporate it into this mature system based on its characteristics."

"This kind of division will allow people to understand a strange plant in a very short time. Do you know cabbage, but don't you know mustard and cabbage?"

"It doesn't matter. Through observation, we can find that they are all Brassicaceae. Yes, open page 43 of the first textbook. The three flowers drawn above are cabbage, mustard and cabbage."

As Alexis narrated, the little wizards below silently opened the first textbook and turned to page 43.Three similar but different flowers appear before your eyes.

"We know that cabbage is edible, so cabbage and mustard greens, which both belong to the cruciferous family, are most likely edible. Perhaps the first person to discover that mustard greens and cabbage are edible just saw that their flowers are similar to cabbage."

Alexis made a little joke, but no one dared to laugh.

Two days ago, it was rumored that Alexis and Hagrid conspired to enter the Forbidden Forest and killed a unicorn. This was a terrible act for the students.Although nothing happened in the end, and there was no news to confirm the accuracy of the rumors, the students did see Dumbledore taking people to Hagrid's hut.

Before they could figure out whether Alexis was a amiable gentleman or an evil dark wizard with a human face and a beast's heart, they always behaved very reservedly in front of Alexis.

"Look, our ancestors used this simple and efficient induction method to help us explore and understand the world."

Alexis didn't care what the students were thinking, he only knew that since he was standing here, he should teach the class well.

"The Muggle world has inherited this aspect of our ancestors very well and further summarized this method into a system, but the wizarding world has done a very bad job on this point."

At this point, Alexis paused slightly. Sure enough, the little Slytherin couldn't help it.

"Teacher Felix!"

A Slytherin raised his right hand.

"Any questions?"

With a smile on her face, Alexis stretched out her hand to ask the student.

"That's because Muggles are just Muggles. They don't have charms, so they can only rack their brains to think of opportunistic ways."
