Dumbledore? He knows nothing about MC alchemy.

".........In fact, she probably won't be able to glide this time...Do you remember the compound spell I told you about? Flying plus gravity?" Kaisen said somewhat embarrassedly.

"That is to say......"

"Ah."

"Oh my god!" Lupin quickly drew out his wand and searched for Tonks in the sky.

"Ahem, use this." Kaisen patted Lupin's shoulder and handed a red pearl to Lupin.

"What is this?"

"Just throw it at her."

Lupin took the pearl, pulled it up with his wand, and threw it towards Tonks who was still rising.

call out!

The moment the pearl touched Tonks, she fell rapidly. Just as she was about to land, a large number of dense spider webs suddenly appeared around her, preventing her from becoming Tonks-chan's tragic fate.

"Junior...are you going to kill your senior?" Tonks crawled out of the spider web with difficulty, lifted her hair with a lingering look, and said helplessly.

"It's all an accident. Do you want to go find Madam Pomfrey?" Kaisen said somewhat embarrassedly.

"Not yet..." Tonks shook her head and helped Lupin to his feet. "Can we do it again?"

Kaisen opened the magic book with a speechless look on his face and edited the last gravity into gliding.

Then she took flight again.

"Where's the pearl? Give me the pearl." This time, Lupin had prepared the flying spell and was ready.

"Not this time. This time it's gliding, not gravity."

Kaisen explained.

"Oh...that's good."

Kaisen was not interested in studying these two infatuated men and women anymore. He took two deep breaths of fresh air and returned to the castle.

He also had to prepare for tomorrow's class. He wasn't too worried about the little wizards other than the third graders making Wither Amulets. After all, even the fourth graders had a year of basic alchemy and runes.

Now we are only three years away from the first grade, and except for a few talented monster scroll kings, it can be said that everyone is a little kid with zero basic knowledge.

So throughout the year, he treated all other alchemy courses equally, but when it came to the Wither Amulet, he placed most of his focus on the third-year wizards.

It’s not that this Wither Amulet is so important, but the opening of Hogsmeade in the third grade.

He knew this group of young wizards too well. They had been envious for two years of seeing the senior wizards spending money lavishly in Hogsmeade. This year they finally had the chance, but it was almost impossible to get them to stay in the castle obediently.

If it were in previous years, it would be fine, but this year there are swarms of Dementors outside. If something happens, even if Fujita married an acromantula, it wouldn't be enough to deal with it.

..........................

the next day..........

"Class, forget it, don't stand up. I looked at the calendar these days and found that you will be able to go to Hogsmeade in a few weeks, right?" Kaisen said with a smile while standing on the podium.

The young wizards in the audience nodded subconsciously, and at the same time felt a chill at Kaisen's weird smile.

There are also differences in smiles. For example, the last time Kaisen smiled like this, it seemed like they had been wearing glasses for a whole semester. In addition, Defense Professor Lockhart was persecuted and dared not leave the office. The time before that, Quirrell had to lie in the medical wing for a whole semester.

The young wizards used their little brains and quickly thought of the similarities between the two events. Draco immediately raised his hand and asked, "Professor, do you need us to help you assassinate Professor Lupin?"

The corners of Kaisen's mouth twitched uncontrollably: "Ahem, this is totally unnecessary. Really, you should have read Professor McGonagall's notice."

The little wizards all looked as if someone in their family had died, and nodded helplessly.

"Actually, I originally wanted to add the Patronus Charm. You could choose between the Patronus Charm and the Wither Charm. If you mastered either, you could go to Hogsmeade. But someone told me that the Patronus Charm is an active skill after all. To be honest, I doubt you would remember to pick up your wands and cast the spell when you saw the Dementors. So... come on, let's take a look at your homework."

Kaisen said this and waved his hand to distribute the homework to the little wizards.

Draco asked again: "Professor, who reminded you?"

"Lupin, what's wrong?"

Draco touched his nose helplessly: "So I can't help you assassinate the Defense Against the Dark Arts professor this year?"

Kaisen's voice became a little stiff. "In fact, I don't even need you to help me assassinate the Defense Against the Dark Arts professor. If I need you, I can do it myself."

"Okay..." Draco lowered his head helplessly. The evil plan given to him by Professor Snape might not be completed for the time being.

Kaisen looked at the depressed reactions of the young wizards. Although this mentality might not be very suitable for learning, at least judging from their reactions, they really did not dare to sneak out of the castle.

This one is very good.

"Okay, let's take a look at your homework first, and then we'll officially start the class. Those of you who are called upon by me, please stand up and copy today's blackboard notes ten times..."

..................................

Slowly, the class came to an end, and Kaisen finally wrote a string of runic symbols on the blackboard.

"Okay, little wizards, learning the Wither Amulet is tiring enough. Now let's learn something refreshing to cleanse our souls."

The young wizards stared at the runic symbol on the blackboard with their red eyes.

"These runes are very simple. I just need you to take out your wands and use magic to replicate the runic symbols on your wrists."

Kaisen said with a smile.

The young wizards also began to practice, until Hermione suddenly remembered something: "Professor, what is the use of this rune?"

"It's good to specify, so there's nothing wrong with you writing it."

Although Hermione always felt that something was wrong, she finally wrote the runes on her wrist.

"Alright, this rune is to ensure your safety. Anyone who leaves the Hogwarts grounds without permission will be detected by this rune and forcibly transported back to the castle. Class dismissed."

After saying this, Kaisen quickly left the classroom.

Ah autumn! Ah autumn!

Kaisen sneezed twice in a row and rubbed his nose: "One thought and two scolds... Well, it seems that two people missed me."

Sleepy, want to sleep, poor, want a gift

Chapter 184 Sirius?

"That's actually the case. We still don't know how Sirius Black escaped from Azkaban." Dumbledore said as he and several professors sat in a corner of the headmaster's office.

"I still hold onto my opinion. Sometimes, for the sake of life's safety, one can sacrifice many things, such as happiness, anger, and friendship. I don't think that in order to allow Harry Potter to have a so-called complete student life, one should be exposed to the shadow of Sirius Black."

Snape said dryly, his eyes still flicking to Kaisen and Dumbledore.

But Kaisen ignored Snape, but heard Dumbledore say that he still didn't know how Sirius escaped from Azkaban.

But logically speaking, Dumbledore should know about this. Lupin should have told Dumbledore that Sirius Black is an Animagus.

Being able to escape the gaze of Dementors, being able to escape from Azkaban prison, and even dog paddling from the isolated island of Azkaban to the land.

This should make it easy to sort things out...

Although Dumbledore is sometimes frivolous and likes to play tricks, his IQ is basically normal, even very high.

So what is he pretending?

Kaisen looked at Dumbledore with a strange look, but he did not ask the question directly. He stayed alone until Snape and several other professors left.

"Why didn't you mention Sirius being an Animagus?"

Dumbledore shrugged. "I thought you already knew. To be honest, if you hadn't told me I would have gone looking for you."

"What do you mean?" Kaisen asked with some confusion.

"The big black dog in your office. Lupin told me that Sirius' Animagus is a big black dog. So are there any other options besides the one in your office... After all, as far as I know, ordinary dogs should not be able to... drive a boat." Dumbledore explained.

"That dog isn't Sirius."

"In fact, you are too superstitious about yourself, and you underestimate yourself too much. Let us recall, in which winter, in which forest, on which cliff did your future self face us, and who was the person next to him?" Dumbledore asked.

Kaisen was a little stuck for a moment: "I really forgot about that. Are you saying that Sirius was rescued by my future self?"

Dumbledore nodded: "Yes, this also explains why he was able to get rid of your monocle." Dumbledore gently took the glasses off Kaisen's eye sockets and put them in front of his eyes and said.

"..............Do you have any way to verify it? After all, you told me that I have lived under the same roof with a man for such a long time...To be honest, it's quite............"

"Animagus counter-curse. This is a relatively uncommon spell. I'll tell you the spell later."

"........................"

"Okay, I'll go with you."

The two left the office and headed towards the alchemy office. "If your deduction is wrong, will this Animagus counter-curse harm Bruce?"

"Not really. If he wasn't Sirius... he might not be able to eat for a few days, because magic can sometimes sustain life," Dumbledore explained.

"Ok."

Soon the two pushed open the door of the alchemy office. This time, Bruce did not go to Gryffindor Tower to eat and drink, nor did he go boating on the ice track. Instead, he took a comfortable nap in the botanical garden near the floor-to-ceiling windows.

"Why are all the trees you planted square?" Dumbledore asked curiously.

"........................"

"If you don't want to talk about it, then don't talk about it." Dumbledore casually cast a stunning spell on Sirius, followed by an Animagus counter-spell.

Almost instantly, the drooling big black dog turned into a thin man in a shabby suit, which left Kaisen stunned.

Because what he saw through the monocle at this moment was still the entry of [Beast].

But he soon discovered the trick. He saw a plain ring on Sirius's finger. He took off the ring, and this time Sirius's entry became normal.

[Human] [Magic]

He looked at the ring in his hand again, but couldn't see anything.

"It seems that I will be quite awesome ten years from now." Kaisen waved his hand and was about to restrain Sirius who was lying on the ground with his face up, but was stopped by Dumbledore.

"what."

Dumbledore said nothing, but waved his wand to undo the Animagus counter-curse, and soon he was transformed into a large black dog again.

"Let's go back to the principal's office and talk." Dumbledore said and Apparated out of the office.

Kaisen rolled his eyes and followed. After returning to the headmaster's office, he asked bluntly, "Are you saying that Sirius has been found out, and he and Harry have spent a lot of time alone together, so you suspect that he is really a bad person?"
