Dumbledore? He knows nothing about MC alchemy.

"Oh well."

Soon the three of them returned to the ground. Every time the goblin tried to get close to Kaisen, he was scared away by Hagrid's ferocious look. He didn't smile again until they walked out of Gringotts.

"Let me see. Next we have...books, robes...let's divide the work. Harry, you take the money to Madam Malkin's robe shop, and Kaisen, you go buy a set of books for Harry, just buy the whole set for the first grade...I have some personal matters to attend to. Dumbledore asked me to go to Knockturn Alley." Hagrid looked at Kaisen and said.

"Yeah, no problem. Harry, wait for me at Madam Malkin's. I'll come find you after I buy the books. Don't get lost by yourself." Kaisen nodded and walked towards Flourish and Blotts.

Arriving at the bookstore, he first asked for a set of first-grade magic books, and then packed up the basic alchemy books in the bookstore. Although the alchemy books in the Hogwarts library were more advanced, it had to be said...

It's a bit too advanced and he can't understand it.

He summoned an ender chest, stuffed all the books into it, and then crushed it. It collapsed into dark green pixels and dissipated in the air. Everyone else thought it was just an exquisite alchemical creation.

For example, a...a platinum father and son.

"It's a very exquisite object. Is it the work of an alchemist?"

Kaisen looked at the person who said this, a little boy with platinum hair, and someone with the same hair color as him... who looked like his father, none other than Draco Malfoy and Lucius Malfoy.

"I made it myself, it's not worth mentioning."

"Are you an alchemist?"

"Draco." Lucius patted Draco on the back, not knowing what he was dissatisfied with.

"Oh..."

"Lucius Malfoy." Lucius took off the gloves on his hands and handed them to Kaisen.

"Kasenhis." Although Kaisen didn't know why the man wanted to shake hands with him, he still remained polite.

Chapter 9 Obtaining New Blocks

"I have long admired my name."

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

"As a Hogwarts governor, it is naturally necessary for me to know every professor at Hogwarts, such as the new alchemy professor, Mr. Kesenchis." Lucius said reservedly.

"Oh, I've heard a lot about you. I've heard a lot about you." Kaisen said politely.

"This is my business card with the address of Malfoy Manor on it. Malfoy Manor welcomes you to visit." Lucius took out an emerald green card and handed it over.

"I will."

The two exchanged pleasantries for a while before Kaisen left Flourish and Blotts. As for the Malfoys, they were still choosing books in the bookstore.

Draco was choosing when he suddenly said, "Father, I've never heard of the Heath family before."

"You're asking why I should show kindness to him even though he's suspected to be a Muggle-born?" Lucius responded.

"Ah."

"Dumbledore said that this Kesenhith was an old-school apprentice wizard. Whether he was a Muggle-born or not remains to be determined. After all, from the information I found, Kesenhith was an orphan, so he wasn't necessarily a Muggle-born."

"And his alchemy attainments are truly powerful. This is enough for me to ignore his bloodline. Moreover, the so-called pure blood is because pure blood can bring us tangible benefits. If the title of pure blood cannot bring us benefits, it may even bring us disaster..."

Lucius paused at this point, obviously waiting for Draco to add something, but unfortunately...

“…”

"If this name can't bring us benefits and reputation, we must make it infinitely transparent. If this name brings us danger, we must abandon it."

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

Draco was silent for a while and nodded. Of course, it was still unknown whether he had really heard it.

On the other side, in Madam Malkin's robe shop, Kaisen arrived late and found Harry sitting on the small sofa waiting.

"Sorry, it took a long time, didn't it?"

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

"I didn't see him. He said he went to Knockturn Alley." Kaisen shook his head.

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

"Hmm, I don't have any objection, 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 small path came to an end, and Knockturn Alley appeared in front of the two. Its general layout was not much different from Diagon Alley, but it was sparsely populated and the atmosphere revealed a dead silence and solemnity.

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

"Is that Hagrid?" Harry suddenly pointed in a direction, and Kaisen also looked over there. To be honest, Hagrid's size was really obvious at a glance.

It looked like he had run into...a little trouble. Three dark wizards in black robes surrounded Hagrid, as if threatening him with something.

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

"Smash it if you run into danger."

As he said this, he took Harry towards Hagrid.

"Hagrid, what's the problem?" Kaisen shouted to Hagrid from a distance.

"Why are you here? To be honest, I can handle it." Hagrid turned around and looked at Kaisen and Harry walking towards him, and said embarrassedly.

"This is none of your business. Believe me, pretty boy, you don't want to be hit by a blast of black magic." A dark wizard in a black robe threatened in his hoarse voice.

"That's what I said too. Really, if you just get out of here now, you won't get hurt." Kaisen shrugged, not stopping at all.

"You're looking for death, you little brat! I'll tear your heart and bones out!"

A pale green spell rushed towards Kaisen at a rapid speed, but was blocked by a piece of obsidian that suddenly appeared.

"Hey, stay away from my friends! Come at me!" Hagrid, who was in the crowd, saw the dark wizard attacking Kaisen and immediately took out his wand. However, he was accidentally one step slower and his little red umbrella was knocked away by a disarming spell.

Hagrid, who missed the first blow, used his fists directly, but... to be honest, the dark wizard is not a little wizard who is still studying in Hogwarts, and his fists are not as lethal as the curse.

"All three of you will die here today! We said it!" said the dark wizard who cast the spell to attack Kaisen arrogantly.

"Isn't it just black magic? Everyone can do it!" Kaisen frowned, and a withered skull appeared in his hand. The next moment, he rushed towards the black wizard accompanied by ominous black smoke.

The dark wizard was a little confused when he saw the wandless and silent black magic.

Dark magic? Wandless? Silent?

Tough guy?

Oh... he understands, he wants nothing!

The next moment, the Wither Skull exploded in his chest with a bang. Although the target of the Wither Skull's explosion last time was Kaisen himself, it still knew its owner and did not send Kaisen directly to see Notch. However, this dark wizard did not have such concerns.

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

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

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

As the beam of light broke, Kaisen appeared directly in front of him, and a lavender sword pierced the dark wizard's chest at his face.

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

"No...it's okay. I didn't know you were so powerful before. I thought you only knew alchemy, hahahaha!" 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 flowed into Kaisen like water.

Chapter 10 Fishing without Bait

"I know a lot of things, such as construction and decoration. To be honest, if your cabin needs to be rebuilt, just come to me. Really, trust my skills." Kaisen patted the dust off Hagrid's coat and said.

"Yes, I will." Hagrid buttoned up all the buttons on his coat again. As for why he came to Knockturn Alley, which was obviously not a good place, Kaisen did not ask.

The world is not black and white. Anyone who comes to such a place is not a good person, and Kaisen does not have that kind of curiosity.

More importantly, he believed that Hagrid was a good man and would not do such evil and beastly things.

"Now what, back to Hogwarts?" Kaisen asked Hagrid again.

"We're done with our business, and Harry's as well."

As the three of them talked, they came to the Leaky Cauldron. Hagrid had a room in the Leaky Cauldron until September 1st, when school started.

"I don't think you would like to go back to your so-called aunt's house, so please stay here. When the time comes, come directly to this address and take the Hogwarts Express to get to Hogwarts, okay?" Hagrid said as he packed the map and the Hogwarts Express train ticket and handed them to Harry.

"I will, don't worry, don't worry about me."

Harry nodded.

"Well, you can go to Old Tom's for three meals a day. He's a good cook. Of course, Diagon Alley is also fine. As long as you don't go to Knockturn Alley, you'll be safe. Also, I left a surprise for you at Old Tom's. Go take a look." Hagrid added.

"understood."

"Finally..." Hagrid raised his head and looked around. After making sure no one noticed them, he whispered, "The wall of the patio has been repaired. I'm going to tell you how to enter Diagon Alley correctly. There's a trash can in the corner of the patio. Count three bricks up and two bricks down. Tap it three times with your wand. Remember..."

After Hagrid finished speaking, he looked at Kaisen carefully.

"OK, OK." Kaisen shrugged and said.

"Uh-huh, you guys leaving now?" Harry asked.

"I'm sorry, but I still have work to do at Hogwarts."

"Okay then, see you at the start of school."

"Yeah, see you at the start of school."

After saying goodbye to Harry, the two threw two silver Sickles to Old Tom and each took a handful of Floo powder. Kaisen remembered that he had seen how to use this thing in a book.
