Hogwarts: I rely on MC to pretend to be an alchemy professor

"I have long admired my name."

"...Huh? You know me?" Kaisen was a little surprised.

"As the school director of Hogwarts, it is naturally necessary to know every professor at Hogwarts, such as the new alchemy professor, Mr. Kesenheath." Lucius said reservedly.

"Oh, I've admired my name for a long time, I've admired my name for a long time." Kaisen said politely.

"This is my business card. It has the address of Malfoy Manor. Malfoy Manor welcomes you as a guest." Lucius took out an emerald green card and handed it over.

"I will."

The two of them were polite for a while before Kayson left Flourish and Blotts Bookstore. As for the Malfoys, the Malfoys were still selecting books in the bookstore.

Draco made a choice and suddenly said: "Father, I've never heard of the Heath family before?"

"You're asking why I still show goodwill to him when he is suspected to be a Muggle?" Lucius responded.

"Um."

"Dumbledore said that Kesenheath is an old-school apprentice wizard. It remains to be seen whether he is a Muggle. After all, from the information I found, Kesenheath is an orphan, not necessarily a Muggle." Melon seeds.”

"And his alchemy skills are really powerful, which is enough for me to ignore his bloodline. And the so-called pure blood is because pure blood can bring us real benefits. If the name of pure blood cannot bring us When it comes to profit, it may also bring disaster to us..."

Lucius paused when he said this, obviously waiting for Draco to add, but unfortunately...

"..."

"If this name cannot bring us benefits and reputation, we will make this name infinitely transparent. If this name will bring us danger, we will give up this name."

"What is precious is never the so-called pure blood, but the real benefits, do you understand?" Lucius had no choice but to tell all the answers himself.

Draco was silent for a while and nodded. Of course, it was still unclear whether he really listened.

On the other side of Madam Malkin's Robe Shop, Kayson arrived belatedly and found Harry sitting on the small sofa waiting.

"Sorry, it took a long time?"

"It's okay, where is Hagrid?" Harry smiled and stood up.

"I didn't see him. He said he was going to Knockturn Alley." Kaysen shook his head.

"Let's go find him. I remember seeing a Knockturn Alley sign before."

"Hmm, I don't have any objection, then let's go."

The two found the path leading to Knockturn Alley. There were not many people along the way, and some were just decadent wizards huddled in the corner.

Soon, a path came to an end, and Knockturn Alley appeared in front of them. The general layout was similar to that of Diagon Alley, but it was sparsely populated, and the atmosphere also revealed a sense of deathly silence and chill.

"It doesn't look very serious. What is Hagrid doing here?" Kaison curled his lips. He didn't like this kind of lifeless place, and it was obviously not a good place.

"Is that Hagrid?" Harry suddenly pointed in a direction, and Kaison also looked there. There is a saying that Hagrid's size is really easy to spot at a glance.

It seemed that he had probably encountered...a little trouble. Three dark wizards in black robes surrounded Hagrid, as if they were threatening something.

"Follow me, don't run too far." Kaisen said to Harry, but still a little worried, he summoned an ender pearl and gave it to him.

"Crush it when in danger."

With that said, he led Harry towards Hagrid.

"Hagrid, what's wrong?" Kaison shouted to Hagrid from afar.

"Why are you here? To be honest, I can actually handle it." Hagrid looked back at Kaison and Harry walking towards him, and said a little embarrassedly.

"It's none of your business. Trust me, pretty boy, you won't want to take a shot of black magic." A dark wizard in black robes threatened in his hoarse voice.

"That's what I said. Really, if you get out now, you won't be harmed in any way." Kaisen shrugged, not stopping at all.

"The boy who is looking for death, go to the heart and dig out the bones!"

A green curse rushed towards Kaisen at high speed, but was blocked by an obsidian stone that suddenly appeared.

"Hey, stay away from my friends! Come to me!" Hagrid, who was in the crowd, watched the dark wizard among them attack Kaison, and immediately took out his wand, but accidentally took a step behind and was hit by a The disarming spell knocked the little red umbrella away.

Hagrid, who missed the hit, used his fists directly, but... to be honest, the dark wizard was not a young wizard still studying at Hogwarts, and his fists were really not as lethal as the curse.

"You three have to stay here today! We said so!" the dark wizard who cast a spell to attack Kaisen said wildly.

"Isn't it just black magic? Who doesn't know it?" Kaison frowned, and the withered skull appeared in his hand. The next moment, he rushed towards the dark wizard with ominous black smoke.

The dark wizard was a little confused when he saw the black magic that was being cast silently without a wand.

Black magic? No stick? silent?

Hard work?

Oh...he understood, it was lifeless!

The next moment, the withered skull exploded in his chest with a bang. Although the target of the withered skull explosion last time was Kaisen himself, it still knew its owner after all, and did not directly let Kaisen go to see Notch, but this black wizard did not have such concerns.

The explosion, together with the effect of withering, directly took his life.

The other two black wizards who were still attacking Hagrid also understood that Kaisen was a tough guy, so they ran away directly.

Just as the two of them were about to Apparate, a withered skull directly blew up the black wizard who was farther away from Hagrid, and the other black wizard who was closer to Hagrid was hit by a dark green beam.

As the beam broke, Kaisen appeared directly in front of him, and a lavender long sword pierced the black wizard's chest close to his face.

"Is Hagrid okay?" Kaisen drew out his long sword, and as the body fell to the side of the road, the long sword in his hand disappeared in time.

"No... It's okay. I didn't know you were so good before. I thought you only knew how to do alchemy. Hahaha!" Hagrid picked up the little red umbrella wand on the ground, scratched his head and said.

At the same time, the trust from Hagrid and Harry also flowed into Kaisen's body like water.
