I swung a sword at Hogwarts

The Defense Against the Dark Arts class was over. This was definitely Slytherin's least favorite class.

Malfoy stopped Harry and sneered, "That's great, Potter."

"What did you want to say, Malfoy?" Harry looked at Malfoy warily.

The two of them were so angry just now that they ignored the conditions of the silent spell and cursed each other.

Sirius tried to stop him, but was cursed by Malfoy, and Slytherin was deducted 5 points.

The points John added were gone in an instant, and Slytherin's points hourglass became the minimum.

This is the first time I've seen this.

Malfoy didn't say anything, just sneered a few times and left.

...

hall.

Malfoy said vividly how he cast a tap dancing jinx on Harry.

John looked at his strange bowl of egg fried rice.

Daphne looked calm, but those who knew her well knew that she was about to cut the plate open.

Both of Daphne and him are top students, equally good.

Although Daphne is stronger, some spells cannot be cast under the conditions of silent spells, and neither of them can do anything to the other.

"John, aren't you going to the Defense Against the Dark Arts class anymore?" Daphne asked John.

John took a bite of egg fried rice, thought for a moment and nodded, "Not just Defense Against the Dark Arts, I will have less time to attend other classes."

Malfoy looked up, a little surprised at John's decision.

"So from now on, Slytherin will depend on you."

John glanced at the hourglass and chuckled, "Maintain the honor of Slytherin."

As soon as these words came out, Malfoy suddenly felt that the responsibility on his shoulders had increased.

"Especially Draco, just remember to deduct less." Seeing Malfoy's face fall, John shook his head and laughed, "But you don't have to hold it in if you don't like it."

"We are Slytherins, after all."

John's words gave Malfoy great confidence.

Slytherins are never ones who are afraid of causing trouble!

Lunch is over.

There are two Potions classes in the afternoon.

Malfoy, who was furious about the points deducted in the morning, was determined to make up for it in Potions class.

...

Underground classroom.

When Malfoy arrived, there were only a dozen people there.

This is normal. After all, as Snape's course, no one would be willing to continue to be scolded after being scolded for five years.

In addition to Malfoy and Daphne, Blaise and Theodore were also there.

Of course, when Theodore is around, Pansy is also in love.

As the best friend of a top student, Pansy did well in Potions.

Ernie Macmillan from Hufflepuff was there, and the chatterbox was telling a story about how John had surprised Professor Black.

"Hey, Potter." Malfoy locked his eyes on Harry and gave him a nasty smile, "Welcome to my home ground."

The head of the house likes to deduct points from Gryffindor in class, so Malfoy is smiling so happily.

Harry's face darkened, and he wished he could have another passionate fight with Malfoy.

Ron wailed in despair, "It's over. Snape wants to deprive us of everything."

Harry said unhappily, "Sirius did nothing wrong."

In fact, Harry was also a little uneasy, but more angry.

What should I do if Snape deducts points from me for no reason?

Will Sirius help him vent his anger?

He felt that his godfather would certainly deduct an even greater amount of the money, but that might make the school feel irresponsible and they might expel Sirius.

Harry was worried because he didn't want Sirius to be expelled.

Just as Harry was feeling mixed feelings of worry and anger, the door to the dungeon opened.

A big belly protruded first, which was obviously not a figure that Snape could have.

"Professor Slughorn?" The students looked at him in amazement.

Slughorn smiled and said, "Your Potions professor has something to do, so I'm here to fill in for him."

He said it tactfully.

After all, it was really embarrassing to let people know that Snape was so angry about Sirius that he couldn't come to class.

As a substitute teacher, he was not angry, on the contrary he was quite happy.

This is not the first time that the principal has substituted for a teacher. Dumbledore has also substituted for a teacher before.

As the former head of Slytherin, he also teaches Potions.

He was very interested in teaching students again after a long absence.

Especially since there are 'collections' among this group of students that he hopes to own.

The students walked into the classroom in a daze.

What was different from before was that the place was filled with steam and all sorts of strange smells.

Slughorn looked around, looking at the dozen students again and again, and finally said in disbelief, "Why isn't John here?"

Yes, not here.

John didn't come to class at all.

Confused, he said, "I remember he chose Potions."

As the biggest factor that made him "condescend", he actually didn't come to class?

Perhaps it was because his disappointment was too obvious, and the students looked at each other in bewilderment, or Malfoy said, "John has a lot of elective classes, and he also has to prepare some things for research."

"Oh, I see." Slughorn remembered something and said happily without feeling disappointed. "It's okay. I don't mind, Malfoy."

Ron whispered to Harry, "He doesn't even care about John skipping class, can we do the same?"

Hermione rolled her eyes at him and said, "You need to have the Order of Merlin."

This made Ron shut up.

Harry noticed what Malfoy said and what he was researching, and wondered, "What is John researching?"

Just as he finished speaking, he saw Hermione angrily saying, "You're doing this again! Are you going to suspect John of researching something bad?"

"I do not have……"

I swear to God, Harry was just asking casually.

Hermione is now in a mindless protective state towards John. If two people say something bad about John, she will glare at them.

The students sat down, the Slytherins sat at one table, and the three little ones also sat at the table closest to the golden cauldron.

Slughorn's teaching was different from Snape's.

His lectures are full of interaction.

For example, now, in addition to the golden crucible that exudes an alluring aroma, there are three more crucibles.

Malfoy's originally rebellious expression turned into an expression of intoxication and joy after he smelled the scent in the crucible.

"What is that? It smells like pear blossoms, a little bit of pumpkin juice and a Firebolt broom."

"Wait, the Firebolt broom smells different from other brooms?" Blaise was a little confused.

Are you afraid that others don't know you have a Firebolt?

Daphne also sniffed it carefully, and a scent of pine entered her nose, as well as a faint smell of golden star wine.

She blushed slightly as she recognized what it was.

"Okay, okay, okay."

Looking through the rising steam, Slughorn's figure seemed to be floating.

"Students, please take out your scales, medicine bags, and don't forget to take out your Advanced Potion Making textbooks."

As he spoke, Harry raised his hand.

"What's the matter, Harry?" Slughorn looked kindly.

"I have no books, nothing, because we didn't expect to have advanced classes." He didn't want to come at first, but Professor McGonagall forced him to come because a certificate in Potions is a requirement to become an Auror.

In addition, the conditions that Snape had previously stated had to be met have changed.

Because the people who meet the requirements are all the ones Snape doesn't want to teach, and there is one person he can't teach.

He could only adjust the conditions.

But this statement may be questionable.

"Ah, yes, Professor McGonagall mentioned this," Slughorn remembered, not minding, "Don't worry, kid, you can use the ingredients and tools in the cupboard first."

Hearing this, Harry and his fellow sufferer Ron walked to a storage cabinet in the corner.

They had never opened this cabinet before.

After opening it, some old textbooks and tools are placed here.

One of the books was so tattered that the cover was about to fall off, but the other one was much better.

After exchanging a glance with Ron, the two brothers simultaneously grabbed another better book.

After two and a half minutes of fighting, Ron pushed Harry away with a heavy push.

Harry was at a disadvantage because he was not as tall and strong as Ron, so he had to pick up the old book.

"I'm sorry, buddy can block the curse for you, but the new book must be mine." Ron said proudly.

Harry was furious, so he got another set of scales and some materials and they returned to their position.

Slughorn didn't care about this little episode. He stood in front of the classroom and said with a smile, "I have prepared a variety of potions for you to broaden your horizons. Of course, it's just for fun."

"Once you finish the advanced class, you should be able to make something like this."

"Okay, can anyone tell me what this one is?"

He pointed with a smile to the cauldron closest to the Slytherin table, which contained a potion that looked like clear water.

Two hands were raised at the same time.

At the Slytherin table and the Gryffindor side respectively.

The two girls looked at each other, and sparks seemed to burst out from the void.

"Calm down, Miss Greengrass, and answer me." Slughorn rubbed his eyes to make sure that the sparks were just his illusion.

Daphne glanced proudly at Hermione who was not named, and said, "Veritaserum, a colorless and odorless potion that can force anyone who drinks it to tell the truth."

"Very good, very good!" said Slughorn, delighted with the people he had invited on the train. "Now, can anyone tell me what that one is?"

He pointed to the second crucible and continued, "This one is more famous..."

Before he finished speaking, two more hands were raised.

Slughorn looked from Daphne to Hermione.

He chose Daphne again.

"It's a compound potion. By adding hair, after drinking it, you can change into the appearance of the owner of the hair." Daphne answered the question.

"Excellent, excellent!" Slughorn was about to applaud her and pointed to the third, golden cauldron.
