Dumbledore? He knows nothing about MC alchemy.

"See, I told you that was too much gold." Hagrid was still angry.

"Forget it, Hagrid... and you too. That piece of gold is genuine. Don't worry that I'll use tricks to deceive you. Now's your last chance. If you don't return the excess, I'll make up for the shortfall. If I'm gone, you'll have no chance." Kaisen shrugged and said to the family of three in the corner.

"...No no no...No thanks."

"Uh-huh, let's go."

The three of them got on the motorcycle, with Hagrid and Kaysen sandwiching Harry in the middle.

However, looking at the thin boy sitting in front of him who was only as tall as his chest, Kaisen simply took off his raincoat and put it on Harry.

[Favorability from Harry +10]

[Favorability from Harry +10]

Kaisen didn't care about the favorability. He was really afraid that the cold air at night would freeze an eleven-year-old child to death. Besides, he had a windbreaker even though he had no raincoat, and Hagrid in front of him had to run naked without his coat.

"Thank you." Harry, who was sitting in the front, whispered.

"It's okay, Hagrid, hurry up."

Almost early the next morning, the three of them took the subway and then a taxi, and arrived at the Leaky Cauldron somewhat tiredly.

It's not some other bad things, such as being discovered by Muggles while riding a motorcycle in the sky. It's simply because the motorcycle doesn't have enough horsepower. Maybe the power of a giant plus an adult is its limit.

Adding Harry to the mix, it was a bit too much for it.

If I hadn't placed blocks all the way on the sea surface last night, they might still be soaking in the sea water.

After all, none of the three can Apparate, and the teleportation distance of the Ender Pearl is really limited. It can improve mobility during combat, but it is difficult to travel long distances.

The three of them walked into the Leaky Cauldron and looked at Harry curiously with everyone in the bar. Similarly, Kaisen was also looking at the bar, but unfortunately, there was nothing particularly magical about it. After all, the most magical place in the whole of England and Scotland was Hogwarts.

After Hagrid exchanged pleasantries with everyone in the bar for a while, he realized that he couldn't get away, so he looked at Kaisen for help.

"How about you take Harry to Diagon Alley to buy some things for me? The things he needs for the start of school are in his notice. Please, I'll come find you after I have a few drinks."

Kaisen shrugged and said, "No problem."

He naturally led Harry to the back door of the pub and came to a patio...

"Diagon Alley?" he murmured in confusion.

"You don't know either?" Harry raised his head curiously and said.

"Uh uh uh... no need for honorifics. I was pretty much like you before. Anyway, I've never been to Diagon Alley."

Harry nodded and pressed his ear to the wall.

"Is it behind the wall? I heard a lot of noises behind it."

"Maybe, stay away from it." Kaisen said as he pulled Harry away from the wall, then knocked the wall in front of him twice with his knuckles. With two thuds, a 1m×2m corridor was hammered out by him.

"Hurry up, hurry up, get in before anyone comes after us for vandalizing public property." Kaisen said hurriedly as he pulled Harry into Diagon Alley. In just two breaths, the two of them looked around Diagon Alley curiously as if nothing had happened.

Then they both remembered their business at the same time. Kaisen took the admission letter and looked at it.

"Wands, cauldrons, robes...hiss...so many things, let's start with the wands." As he spoke, he raised his head and looked around the plaques in Diagon Alley, and found the only shop related to wands.

"Come with me."

The two walked into Ollivander's Wand Shop. Harry looked curiously at the dazzling array of wands on the wall. Kaisen was also curious, but he chose to go straight to it and compare it with the wand in his own hand.

"That... rose vine with phoenix tail feathers, whose work is that? It's not a style found in any of the three major European wand shops."

An old man with silver hair appeared behind a shelf and looked at the wand in Kaisen's hand.

"This one? This is a feather Dumbledore gave me. I made it myself using rose vines." Kaisen turned around and saw the gentleman who was suspected to be the owner of the shop. He put the wand that did not belong to him back in his hand with some embarrassment and explained.

Ollivander looked at Kaisen's young face and nodded: "Very good alchemical talent."

"uh-huh."

"Are you from that family? I've never seen you before."

"Uh, it was a Muggle before."

"Were you in England before?"

"Yes, but not at Hogwarts."

"Durmstrang? Or Beauxbatons?"

"Uh... wild way."

"Is that so... do you have a job?"

"Yes, the Alchemy Professor of Hogwarts."

"I can give you one...ah?" Ollivander was about to say something, but suddenly held it back.

"It's okay, Mr. Potter, we finally meet." He put on a smile again and looked at Harry who was standing behind Kaisen.

"Hello sir."

"Go ahead and buy your wand. I'll be waiting here for you."

Kaisen said, patting Harry on the back.

Chapter 8 The Evil Demon

Holly wood and phoenix tail feathers, this should be the combination.

It was mainly because he had been in a daze just now and didn't remember it very clearly. It was not until they left Ollivander's and met Hagrid who was late and asked him about it that he remembered it.

Hagrid was talking non-stop about the interesting things that happened in the patio of the Leaky Cauldron.

"You don't know. You don't know which genius it was. He probably didn't know how to get into Diagon Alley, so he just destroyed the brick wall. Seriously, didn't he even think to ask Old Tom about it?"

There was a moment of silence between Kaysen and Harry.

"Why do you have such expressions? Are you the ones who caused the destruction?"

"..."

"You guys aren't the ones who are destroying it, are you?"

"..."

"......Hurry up, hurry up, those Aurors are going crazy looking for you, hurry up." Hagrid took a deep breath and hurriedly led the two of them into the crowd.

"By the way, did you go to Gringotts?" Hagrid suddenly asked as they walked.

"...What's Gringotts?" Harry asked, looking up.

"That's the white building, the wizarding bank. Dumbledore happens to be keeping the key to your family's vault, so today is the perfect time to return it to its rightful owner... and I need to go to Gringotts for something."

The three of them arrived at Gringotts and boarded a mine cart heading to the underground vault.

"Is this thing safe?" Kaisen asked curiously, his mouth twitching.

"Don't worry about that. Safety is Gringotts' first priority." The goblin sitting in the front row turned around and explained.

Slowly, the mine cart started to move. Kaisen, sitting at the back, watched the surrounding scenery constantly passing by and subconsciously cheered: "That's awesome!"

"......"

"Is it noisy?"

"No...that's awesome!" Hagrid cheered along.

Then the two of them went to their respective vaults, leaving Kaisen alone leaning against the stone wall in a daze.

He had no idea of ​​opening a vault. If there was something, he only needed one box to put it. If one box was not enough, he would upgrade it to a growth box.

Soon, Hagrid seemed to have finished getting his things and stood aside waiting for Harry.

"Why is that kid so slow?"

"I do not know..."

When the two were curious, Harry finally came out with a big bag of gold galleons and walked straight towards Kaisen.

"...I have a feeling..."

As expected, Harry handed the sack full of gold Galleons directly to Kaisen, but he didn't take it. He really didn't take it. To him, gold was really no different from the cobblestones on the roadside. It would be better to give him an unfinished house for him to decorate than to give him gold.

"What are you doing?"

"Pay back the money."

Kaisen looked at Hagrid somewhat innocently, obviously wanting him to help persuade Harry.

Hagrid shrugged. "Take it. It's a token of Harry's kindness, and you did help him repay the Dursleys."

"Can't you help persuade Harry..."

Kaisen complained somewhat speechlessly, then squatted down and patted Harry on the shoulder. "To be honest, I'm not good at chatting with children, but there's really no need for you to do this. Really, maybe you don't know, I'm an alchemist. Gold is of no use to me. Don't take it to heart. Now put these gold coins back."

Harry looked at Kaisen, then at the sack of gold Galleons in his hand and shook his head.

"...Hagrid, please help me persuade him."

"I...how can I persuade you? This is given to you by Harry, why don't you keep it? I remember that the Potter family's treasury is quite rich."

"Then I can't ask for money for a child... and you're... a bit looking down on me. Really, I'm not short of money." Kaisen said earnestly.

"so..."

"So, as your future alchemy professor, my first lesson is that while you shouldn't be stingy with your friends, sometimes spending money lavishly can have the opposite effect on friendship."

"Okay." Harry looked a little sad as he carried the sack back to the vault.

Kaisen also breathed a sigh of relief. According to the same principle of conservation, even if he lost gold Galleons, he would also gain a series of favor from Harry.

The two of them were still leaning against the stone wall waiting, while the little goblin who had been standing in the corner came over with a mean look on his face.

"Sir, are you an alchemist? And a professor at Hogwarts?"

Kaisen looked down at the goblin and was about to nod when Hagrid blocked his way.

"Stay away from my friends."

The goblin left dejectedly, leaving Kaisen stunned. "Why?"

"Goblins are evil creatures, so avoid them if you can," Hagrid said seriously.
