The third Dark Lord came from Hogwarts

The old man was very angry.

"It's... a soothing potion..."

Slughorn showed a hint of surprise in his eyes.

There are quite a few types of potions that can be made with these materials.

There are two or three that have been learned in the first and second grades alone.

I didn't expect that Argus would choose the soothing potion that he learned in the fifth grade, which is one of the most difficult potions to handle in O.W.Ls exams.

As a potion that can calm and soothe manic emotions, the soothing potion has strict requirements on the ratio of materials.

Too much moonstone powder will make the person who takes the medicine fall into a drowsy or even irreversible sleeping state.

Too much sneezeweed essence syrup will greatly reduce the effect of the potion, wasting precious potion materials in vain.

Slughorn was originally a pure-blood of the 28th Clan, and had taught at Hogwarts for many years, with many students under his command.

These materials might be considered expensive to ordinary potion masters, but for him, they were just a piece of cake.

He might not even be willing to bend down to pick them up if they fell on the ground.

He watched Argus's next steps with interest.

Argus did not get flustered by Slughorn's observation, and put the materials into the crucible in an orderly manner.

According to the operation in memory, he gently stirred the solution in the crucible.

Five minutes later, the lavender liquid was poured from the crucible into the container prepared in advance.

The mist floating above exuded a cool mint-like smell.

"Professor, it's done."

Slughorn stepped forward to check, with a satisfied expression on his face.

In fact, when Argus was making the potion, he had the result in mind.

A second-year wizard could choose the correct potion formula in this situation, and could also skillfully make complex potions that would only be learned in the fifth grade.

It is definitely not something that can be learned by just processing materials in the office every day!

Talent and diligence are both indispensable!

He took out a few notebooks from his suitcase and put them on the table.

"Don't waste your talent for potions."

"Here are some of my thoughts on potions, for you."

"If you don't understand anything, ask me or Severus."

"Thank you, professor." Argus did not make false excuses and agreed generously.

"I have some questions about teaching that I would like to ask you."

Argus knew that this substitute class was a good opportunity for him to improve his reputation.

He wanted to achieve the best effect possible.

But he had never taught a class before, and he lacked experience in this area. He still needed to communicate and learn from several deans and professors.

...

That night.

Hogwarts announced a series of changes to the Defense Against the Dark Arts class.

While adding classes, clubs were created for fifth- and seventh-year students, and activities were held in the Defense Against the Dark Arts classroom every night before curfew.

Mainly for review for wizard exams.

All fifth- and seventh-year students can participate.

"Finally, the class is about to start! If it doesn't start, I'll really be mad!"

"Did they say anything about the extra classes?"

"Not yet, it should be announced by the dean."

"What's the club mentioned above?"

"I don't know, let's go and see when the class starts in two days, but I don't think it's useful, what can we do with so little time?"

"That's true!"

Argus listened to a group of wizards arguing around the bulletin board at the entrance of the hall.

Most people are pessimistic about the club before curfew.

This is normal, after all, there are few evening self-study classes in the West, and they have never heard of exam-oriented teaching.

If you want them to accept it in a short time, you must come up with certain results.

The purpose of proposing this method to Slughorn was never to let them pass the exam.

To put it bluntly, whether they pass or not, what does it have to do with him?

What Argus wants is that after they pass the exam, they will know that these methods were proposed by him!

The joy and excitement of passing the exam will all turn into gratitude to myself.

By then, my influence will officially expand to the entire Hogwarts!

Due to my age, I have few opportunities to influence the seniors.

This time, I must maximize my influence!

"Head, didn't you go to see Principal Dumbledore? What does the notice board mean?"

Scamander, the former head of the fourth grade who just got promoted to the fifth grade this year, whispered to Argus.

As the head, he naturally didn't worry about the exam.

But at least he had to ask for his classmates. He couldn't just wait and see.

Don't do it.

"In short, the club activities before curfew are targeted review of O.W.Ls, all for exam preparation."

"If you have nothing to do, it's best to join."

Argus only hinted slightly, and Scamander understood what he meant.

This club is very helpful in improving grades!

Join if you can!

"Understood, Chief, I'll go talk to the fifth-year students right away!"

"Make sure everyone is present!"

...

The next day.

Defense Against the Dark Arts class.

The second-year members of Slytherin and Gryffindor sat upright at the table.

"Huh? Where is the Chief?"

Goyle sat next to Draco, stretched his neck to look for a long time, but didn't see Argus.

"Yeah, why didn't Argus come? Isn't he late?"

"Should you cover for him?"

Draco thought Argus was delayed by something, and looked around anxiously.

His words attracted the attention of many Gryffindor members.

They still remembered the hatred between Slytherin and Gryffindor last time.

They hated Slytherin's chief Argus even more!

However, the other party did not give them the opportunity to catch them, so even if they wanted to use tricks, they could not find the opportunity.

And today, they finally waited for it!

Several people seemed extremely excited, rubbing their hands and waiting for the professor to come and complain!

"Great! The head of Slytherin's house is openly late for the new professor's first class!"

"Isn't this clearly showing that he doesn't give the new professor face?"

"That's right, he will definitely be severely deducted a few points by the new professor!"

"Tsk tsk, this is the first time that the head of the house has been deducted points for being late? What the most talented student in Hogwarts is, he is almost the same as us!"

"I want to see how these Slytherins will have the face to show off in front of us!"

Several Gryffindor members were smug and looked at the Slytherin members jokingly.

It seems that Argus is sure that the new professor will establish his authority.

Daphne's face was full of worry.

"Pansy, the head hasn't come yet! Is there something wrong?"

"I remember that the last time the head disappeared was because he was injured in the Chamber of Secrets... Will this time..."

"Bah, bah, bah, crow's mouth!" Pansy was extremely dissatisfied with Daphne's words.

"Can't you hope for something good?"

"Good things? The good things are that your chief will soon become a joke in Hogwarts! Hahahaha..."

Behind him, a Gryffindor member winked and drew a burst of laughter.

Just then, the door in front slowly opened.

A figure that they were very familiar with appeared in front of them.

Agus stood on the podium with a smile and nodded.

"Hello, students. I am the assistant of your Defense Against the Dark Arts professor."

"From today on, I will be in charge of your Defense Against the Dark Arts class."

"Please open your textbooks and turn to the first page."
