Dumbledore? He knows nothing about MC alchemy.

Filch paused and shook his head. "You should tell Dumbledore first. Don't tell me you're also researching alchemy."

"Actually, I'm not very good at alchemy..." Hermione started to say, but was interrupted by Filch: "Then your alchemy skills can't be compared with Professor Kaysen's, you know? The lamp he gave me last time is still burning, and it has been half a semester, and I don't even need to add fuel..."

Hermione nodded. "Mr. Filch, I understand your respect for Professor Kaysen, but listen, isn't that voice a little too strange?"

Filch frowned and finally put his ear to the office door.

The rumbling sound inside came one after another...

"That sound is so scary. I'm going to find Dumbledore. You wait here for me and don't even think about running away. If you really run away, I'll have to go to Professor McGonagall to ask for you back!" Filch threatened the four little wizards fiercely, and then he ran towards Dumbledore's office.

"So... should we run away? I heard from George and Fred that an unspoken rule at Hogwarts is that there is no punishment for breaking the rules unless you are caught?" Ron suggested.

"I'm sorry, because I've heard similar things, but we've been caught." Hermione shook her head regretfully.

While Hermione was chatting with Ron, the other two had already taken action and started trying to open the door with the Unlocking Charm.

However, it seems that Professor Kaisen's door is not a common mechanical lock or magic lock, but a redstone lock, so the unlocking spell is useless for this poor door lock.

"Wait... redstone gate?" Harry suddenly discovered the blind spot. He touched his pocket and took out a red cube.

"Hermione, do you know how to do a Demolition Charm?" he asked.

Hermione rolled her eyes. "We almost turned Professor Kaysen's office upside down last time, but he didn't bother with us. And now you want to remove the lock on Professor Kaysen's door?"

Harry shrugged. "Headmaster Dumbledore is on his way. This door will eventually be unlocked. Rather than having Headmaster Dumbledore use some incredibly powerful magic to open it, we might as well use redstone now. At least we can still install the outer shell."

"......Okay." Hermione was persuaded by Harry. She took out her wand, pointed it at the door lock and chanted a spell. Soon the outer shell of the door lock fell off, revealing the dense redstone circuits inside, and a lock core composed of very small pull rods, pressure plates and buttons. The lock head was located on several pieces of obsidian and a piston.

"It's opened. Now how do you want to open the lock?" Ron asked.

"Didn't Professor Kaisen teach us to use redstone before?" Harry took out a small piece of redstone and pressed it directly on the circuit made of redstone powder. As the redstone powder emitted a strange light, the lock made of piston and obsidian retracted directly.

Harry turned around and smiled at Hermione and the others: "I have some talent in alchemy, don't I?"

"Yes, now please open the door, Mr. Future Alchemist." Hermione nodded.

"Oh." Harry nodded and opened the door. The next moment, the four of them were buried by the pile of gifts that suddenly poured out from the door.

And Filch finally arrived here with Dumbledore who had arrived late.

"Wow, it seems that you are all buried in the ocean of happiness." Dumbledore bent down and picked up a huge packaging box from the ground, and looked at the ribbon and greeting card on it.

"This is what Kaysen brought you." He handed the gift to Filch behind him.

The latter took the gift with slightly trembling hands, and it took him a while to remember to open it.

Fortunately, Dumbledore stopped him: "Wait until Kaisen comes back. He will give you this gift personally. The surprised smile on your face will be a surprise to him as well."

Filch quickly put the gift down. "Yes, you are right, Professor Dumbledore."

Dumbledore smiled and nodded, looking at the four young wizards who cautiously walked out from the pile of gifts. "I wonder if Kaisen should sigh at your talent when he finds out that you cracked his lock, or replace the poor lock's cover."

"Don't worry, Professor, we will fix it." Neville was still holding the lock shell that fell on the ground.

After turning the page on this little episode involving the lock, several people leaned over to look at the source of the pile of gifts. They saw a place in the corner of the office that was constantly spewing out gifts.

Dumbledore used magic to move the gift that was blocking his view aside, and he could see clearly that the gift was sprayed from a gorgeous dark green box.

"Well, I remember that Kaisen's ring is almost exactly the same as that box, but it's a little smaller... Well, have you satisfied your curiosity?" Dumbledore said and looked at several young wizards.

The four little ones also scratched the back of their heads in embarrassment.

"Now that you've seen it clearly, go back. Now it's time to let Professor Kaisen, who has arrived late, experience this surprise." He waved his hand, and the countless gifts that came out were neatly arranged back in the office and stacked neatly.

But soon a new gift came out and messed up the neat pile of gifts again.

"Lock this door quickly, otherwise they might come out again later." Dumbledore said to Harry hurriedly.

Harry touched the redstone circuit with redstone, causing the lock to retract for three seconds. He took advantage of this time to quickly slam the door back and put the lock shell back on.

The incident in the office ended like this. After that, under Dumbledore's persuasion, Filch had to give up his plan of taking Harry and others to Professor McGonagall's office.

The corridor of the Alchemy Professor's office fell silent again until a little after dusk...

Buzz... [Ender teleportation sound]

thump....

thump......

thump..........

"Wardfa?"

Chapter 60 Which one do you think he wants us to choose?

Kaisen stood in the corridor, looking at the office where there was almost no room to stand.

"...I still overestimated the ender chest. Next time I should make a bigger one."

He sighed, waved his wand, and forced his magic to start sorting the pile of gifts.

the next day......

"This time, the Alchemy Association's team-building activity is shopping in a Muggle city in France, so I didn't give you any magical gifts. After all, that would be as boring as an Englishman going to France to find an English restaurant. Now, Cedric, distribute these gifts."

Kaisen immediately placed the gifts he had arranged on the podium and sat on the chair on the podium. He had already decided that if Cedric moved a little slower, he would be able to slack off during the entire class.

but

Cedric's speed was amazing. It took him about two minutes to hand out the gifts to everyone. Then he sat back in his seat and waited for Kaisen to start his lecture.

"Actually, you don't have to be so fast. Don't you want to enjoy some more time slacking off during class?" Kaisen stood up with an awkward expression, picked up a piece of chalk and asked.

The little wizards below all shook their heads in unison.

"Okay, since you all like my class so much, let's take the test."

"...what?"

After class, he returned to the office with a stack of test papers, feeling satisfied. He had distributed all the gifts for the little wizards in the morning.

Now only the professors' were left, and he began to walk from office to office with gift boxes as big as washbasins.

Although he didn't know whether his colleagues liked Muggle gifts, at least Snape smiled rarely when he saw the complete set of scale weights he had given them.

Until he was brought to Filch.

"I noticed that some of the little wizards in the castle easily make the walls dirty, so I made this thing for you. It has an infinite magic circuit built into it. There is a blue light bar inside this gift, which contains the cleaning spell. To use it, just press the red button on it and let the light from the light bar shine on the stains."

Filch took the gift box tremblingly.

"Thank you, thank you Professor Kaysen."

"You're welcome. If nothing else, I'll go back first. I still have Dumbledore's wool socks here. I bought him two hundred pairs at once."

"Oh, oh, of course it's okay, it's okay, Professor Kaysen."

Dumbledore's gift was the last one he gave, well...it wasn't anything else, it was just that his office had to go up a ridiculously long flight of stairs.

"Dumbledore, come and see the socks I prepared for you. If you change a pair every day, you can wear them for half a year...Where is Dumbledore?" Kaisen stood in the empty principal's office in a daze.

"Eh...but if the principal isn't home..."

He slowly turned his head and looked at the cabinet where Dumbledore usually kept his wine.

“Hehehehe…”

He hummed a song as he came to the cabinet and started rummaging through it. He quickly took out two bottles of wine that looked very valuable, as well as a corresponding magic wine box that could simulate the temperature and humidity required for the wine.

"What good stuff." He opened the wine box and kept it back, because he didn't think these two bottles of good wine could survive until tomorrow in his hands.

And at the same time...

"We want to see Dumbledore. We have something very important to tell him!" Harry and Neville, two of the four Gryffindors, appeared in front of the statue guarding the headmaster's office and asked anxiously.

However, the two diligent statues did not seem to answer their nature, or the statues could not speak in some conventional way, who knows.

In short, the two of them were turned away.

"Well, this time it's confirmed. The portrait was right. Dumbledore is really not in Hogwarts."

Soon the other two young wizards, Hermione and Ron, also trotted over: "Professor Kaysen's office is also... empty."

"Now that's great... the other professors still don't believe what we say... Wait, why do we have to let other professors come? Can't we do it ourselves?" Harry suddenly reacted.

"Do you agree?"

"Professor Kaysen told us that we should calculate the gains and losses when doing something. Between the Philosopher's Stone and our lives, which one do you think he wants us to choose?" Hermione reminded her at the right time.

"Then which one would you choose? Even if you know that Professor Kaysen thinks we should choose our lives." Neville asked.

"I chose the Philosopher's Stone, not because it's so precious, but because I think it would be absolutely no good if such a powerful alchemical item fell into the hands of that dark wizard Quirrell!" Hermione said firmly.

"Then why are you still talking so much? Let's go!"

The four little ones ran all the way to the corridor on the fourth floor. The classroom where the three-headed dog was locked up was now wide open, and music could be heard from inside.

Harry stood at the door and took a look inside before breathing a sigh of relief: "The big dog is asleep. Let's go in quickly."

the other side...

"Wine? Oh, wine, Kaisen. I never liked drinking this kind of wine. I think it's too bland. It doesn't even feel like wine. It's more like grape juice, you know?"

Sitting on the sofa, Hagrid politely declined Kaisen's offer to share the wine.

"You'll want to try something new," Kaisen advised.

"The truth is, I really don't understand how to taste this wine, and it looks like it's worth a lot of money. Honestly, it tastes like grape juice to me, and it's a bit of a waste for me to drink it. You should find someone who can appreciate it."

"No, no, no..." Kaisen quickly waved his hands. "The most important thing in this kind of thing is to have fun. If you make any drink unhappy for the sake of so-called value, that would be a true blasphemy to alcohol."

"Oh... Hearing you say that, I feel a little touched." The sentimental Hagrid spoke with a heavy nasal tone. Kaisen noticed with his sharp eyes that the big guy in front of him seemed to want to give him a big hug, and he was so scared that he quickly waved his hands and summoned two wine glasses from a distance.

"Uh uh uh... No need for the hug. If you think the red wine is tasteless, you can go get two barrels of wine."

"Oh, well, maybe I should find some time to practice my strength control. I notice that you all don't want me to hug you..." Hagrid said as he walked out of the house.

"Because if you hug someone, Hagrid, you can really kill them. To be honest, it's okay for adult wizards, but you must not touch young wizards, as it may cause them to burst." Kaisen said.

Chapter 61: Snap! Buzz...

The four little ones reached the last level and only two were left.
