Dumbledore? He knows nothing about MC alchemy.

Kaisen burped and recalled, well, he did use redstone to make an advanced alchemical induction cooker for Snape.

"Yes what's the matter?"

"Don't get me wrong, this is just a small request. I made a small device based on the redstone theory you taught in sixth grade. However, I accidentally arranged the route incorrectly when I was arranging the circuit. I don't know which one is the real switch. What should I do?" the black-robed man asked softly.

"Where did you get the redstone?"

"A sixth-grade student gave it to me, saying it was a product of their professor's alchemy and asked me to treasure it."

"I see. Just cut off the main redstone route and then connect the redstone blocks to the main redstone route."

"So simple?"

"Haven't you learned runes? They're similar in pattern."

Kaisen's confused mind had almost figured out who the man in black robe was.

If he simply asked Hagrid about the three-headed dog, then he might actually have a three-headed dog by chance.

But as luck would have it, he also asked himself about the redstone. The three-headed dog plus the redstone, anyway, he didn't think there was such a coincidence in the world. From this, it can be concluded that the man in black robe is most likely Quirrell.

But this was just right, because Dumbledore had previously asked him to use a clever method to tell Quirrell how to pass through the piston door, and he was wondering how he should tell him.

As a result, a pillow is given to me when I feel sleepy. Isn’t that perfect?

"Thank you both. By the way, Hagrid, this dragon egg is for you." The man in black robe, or Quirrell, left the dragon egg on the table and left the Hog's Head Tavern.

"Haha, Kaisen! I didn't expect that we would have such a big surprise when we come here to drink, a dragon egg! Haha!" Hagrid was originally laughing as he held the dragon egg in his arms, but he stopped laughing immediately when he saw Kaisen who was pouring wine into his mouth.

"Am I a bit of a fish farmer?"

"What do you say?"

"Sorry, sorry, let's have a drink!"

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

the next day......

"The total is 29 gold Galleons plus 6 silver Sickles. I'll round off the number and give you gold Galleons." The old man with a goatee said in a flat tone.

Kaisen's movement to take out the money froze, apparently he was stunned by the reverse rounding operation.

However, he didn't have much objection to this. He and Hagrid slept in the pub all night yesterday and occupied the table until this morning, which did delay other people's business.

Moreover, the two of them did not miss anything after sleeping for a night, from dragon eggs to galleons. After a whole night, they were still in a crowded tavern.

With security at this level, it wouldn't be a big deal to give him an extra Galleon.

"Thirty Galleons, would you like to count?" Kaisen took out thirty Galleons and placed them on the bar.

"No need." After the old man collected all the gallons, he stood back and continued to wipe his dirty wine glass with his dirty rag.

Chapter 24 The Mirror of Erised

After walking out of the tavern, Hagrid froze instantly, grabbed Kaisen's shoulders and began to shake him.

"Kaysen! Kaisen! You know what? A dragon egg! This is a dragon egg! I've always wanted to raise a dragon! A dragon!"

"OK...OK, a dragon...a dragon, I know, I know."

Kaisen echoed as he was shaken with a look of despair.

"Next, I'm going back to my cabin. I really want to hatch this beautiful creature as soon as possible. By the way, Kaisen, can you help me borrow some books about dragons from the library? Methods for hatching and breeding dragons, and preferably one that can teach me how to identify dragons."

Hagrid was holding the dragon egg in his arms, feeling extremely excited. He kept circling around Kaisen, talking while trying his best to make Kaisen, who had just woken up, unconscious again.

"Okay, I will, I will, please, Hagrid, stop spinning."

Back at Hogwarts, one of them sneakily carried the dragon egg back to his cabin, while the other dragged his dazed body back to the castle.

Kaisen first came to Dumbledore's office, and Dumbledore waved excitedly when he saw Kaisen.

"You really should come see this."

He couldn't help but stand up from his seat, took Kaisen's hand and walked to a corner of the office where a gorgeous dressing mirror stood.

"What did you see?" asked Dumbledore.

"I renovated Hogwarts from the inside out using one block after another." Kaisen said subconsciously.

Dumbledore, on the other hand, showed an indescribable friendly look.

"I have to say, Kaysen, if you were given a Sorting Hat, you would definitely be a Hufflepuff."

"Why?" Kaisen asked.

"Even the dreams are so plain and warm. I can't think of any other college."

"..dream?"

Dumbledore nodded. "Yes, it is a dream. This is the Mirror of Erised. It can reflect the desires hidden in people's hearts. However, for a desire as lovely as yours, I think it's better to call it a dream."

"And, to be honest, I never stopped you from decorating Hogwarts, but I sincerely hope you start with the headmaster's office."

Kaisen knocked the mirror in front of him with his knuckles, and the Kaisen inside responded in kind.

"That will have to wait until I have time. Honestly, teaching students is not an easy job."

"Um, I want to move this magic mirror to another room. Want to join me?" asked Dumbledore.

"With your hands?"

"Of course, with magic." Dumbledore held Kaisen's shoulder with one hand and grasped the edge of the mirror with the other. With a buzzing sound, the two of them and the mirror appeared in an empty classroom.

"Harry will like this gift, but I didn't mean to give him this mirror. I just wanted him to experience it."

"When will you let him experience it? Seriously, why don't you just let him look in the mirror in your office?"

"I don't want to get too close to him too soon after Christmas. It's not the right time yet," Dumbledore explained.

"Oh... Christmas. I would have forgotten if you hadn't told me. I haven't prepared any Christmas gifts yet." Kaisen suddenly trembled.

“Who are you planning to give them to?”

"Everyone at Hogwarts, Neville, Harry, and their friends are no exception, as are my students. The twins love to play pranks, so I plan to make them a little gadget that can blow people away without causing any harm."

"Jordan, he might like a new Quidditch robe. Angelina told me her broom is uncomfortable... and Cedric... and..."

Kaisen kept talking like this, and Dumbledore kept watching the scene with a smile.

"Kaysen, I have to say, you are really full of love."

"Love? Maybe. To be honest, I haven't met my parents yet, but I can feel that they live a good life." Kaisen shrugged and said indifferently.

"Death is a grander adventure, Kaysen."

"Uh..." Kaisen was a little embarrassed. He couldn't tell Dumbledore that his parents really lived well in another world, even though it was similar to what Dumbledore thought.

Forget it, I won’t worry too much about it.

"Oh, I almost forgot. Hagrid and I were drinking at the Hog's Head Inn, and a man in a black robe used a...bet to trick Hagrid into telling him how to appease the three-headed dog. I thought the man looked like Quirrell, so I told him how to open the piston door."

"That's great! It saves trouble, not only for you, but also for Quirrell and Tom." Dumbledore smiled.

"Maybe. Do you have anything else to say? If not, I'll leave." Kaisen asked.

"That's all. And remember to tell Harry how to open the piston door. The four of them scared Madam Hooch and Minerva enough in today's flying lesson."

"And of course poor Mr. Malfoy, who was hung from a tree by Mr. Longbottom's wand."

"Just as Mr. Malfoy hung Mr. Longbottom's Remembrall from a tree two minutes before his doom."

Kaisen curled his lips, but anyone could see the good mood hidden in it.

"Isn't it normal for young wizards to fight with each other, especially when they are evenly matched?"

"Yes, and there are two pieces of good news. Poor Mr. Longbottom has regained his confidence with the support of his dear professor and started to resist the oppression of other young wizards."

"And Harry also demonstrated his extraordinary flying talent during this farce. I have to say, he will be an excellent Seeker, just like his father."

When Dumbledore talked about these happy things, a smile always appeared on his face unconsciously.

Like Kaisen’s junior high school teacher, who was an old lady with a lovely figure.

There is always a smile on his face, with his front teeth showing. He is extremely tolerant and kind.

And wisdom.

"Then I want to congratulate them."

"That's not what I want to say. What I want to say is that they should come to your office. Mr. Longbottom is very eager for your recognition and praise. Now that Harry has walked out of Minerva's office, he is probably rushing to your office." Dumbledore said.

"Oh... is that so? Is there still time for me?" Kaisen asked.

"I imagine Mr. Longbottom would be perfectly happy to wait for you until curfew, even at the risk of being charged with nighttime wandering."

"Looks like I have to go back quickly."

"I really wish you were my own student, even though I might not be good at it." Dumbledore said, pushing his glasses.

"I'll take that as a compliment." Kaisen shrugged and walked out of the empty classroom.

Chapter 25 Riot in the Auditorium

Kaisen did not hesitate to use the ender pearl in the corridor, and in just a few breaths, he arrived at the corridor on the same floor as his office.

The four little ones sat in their office, chattering about something.

"What are you doing there?" Kaysen shouted at them.

"Ah, uh... Professor Kaisen, let's... uh..."

"Never mind. To be honest, I welcome you guys to come over. Come on in."

Kaisen waved his hand, opened the office door, and let everyone in.

He took out some snacks and drinks from the cupboard and placed them on the coffee table.

He still hadn't forgotten Dumbledore's instructions.

"Please wait a moment until I finish this. Of course, you can come and take a look. After your third year, you will start filling out elective courses. Maybe you can try alchemy or something like that."

Kaisen pretended to take out a huge redstone lamp block from under the desk. After violently removing the outer shell, he began to fiddle with the various redstone circuits inside.
