In the end, I can only say that Kayson and Dumbledore made a very dirty deal, and that's how they successfully resurrected the Hogwarts Headmasters office tower.
The reconstruction of the Headmasters office was, one could say, not difficult at all.
After all, Hogwarts' primary building materials are very classic: stone bricks, raw wood, plus carpets and furniture. At most, Kayson just added some artistic windows with small blocks for him.
As for the glass... that's naturally ordinary glass. Even the glass in the Alchemy classroom is ordinary, so what kind of glass would the Headmasters office want?
...Mosaic?
Don't misunderstand, it's mosaic glass.
However, what was unbearable wasn't just the reconstruction of the Headmasters office; what was truly unbearable was that old Dumbledore was even riding a flying broomstick, flying right next to Kayson, touching here and there, and even giving commands.
This was pure amateur guiding a professional.
Until Dumbledore once again said that unbearable sentence to Kayson: "Can you leave me a pipeline from the Headmasters office to the kitchen? I can directly have the House-elves send candies up the pipe using magic."
Kayson took a deep breath and suddenly turned to stare at Dumbledore: "Principal, honestly, if you keep saying these pointless things, I'll throw you into the Black Lake."
Dumbledore dejectedly rode his flying broomstick away: "Actually, the Honeydukes pipeline isn't entirely out of the question either."
With Dumbledore's departure, Kayson finally found a quiet construction environment, and slowly, he entered that flow state belonging to construction.
When he emerged from that state again, it was already dark, and the Headmasters office tower had been completely rebuilt, inside and out, without even a single flaw in the wall brick seams.
"Hmm... I really am a genius!" Kayson said, crossing his arms and using Ender Teleportation to return to his office.
The next day...
Kayson casually picked up a Jianbing Guozi from the Great Hall and walked towards the Headmasters office.
This could be considered a product follow-up, to see the new office, whether Dumbledore was comfortable living in it, if it was suitable, and if anything needed to be modified.
Then he was somewhat surprised to find that the gargoyle statues guarding the office seemed to be out of control.
Dumbledore was poking and prodding the gargoyle statue with his wand, doing who knows what...
Seeing this, Kayson walked over and patted Dumbledore on the shoulder: "What are you doing?" Kayson asked, puzzled.
"The gargoyle's magic control circuit seems to be cut off or suppressed. I'm trying to figure out a way to research it," Dumbledore explained.
"Then you should have told me! I'm the professional," Kayson said, exasperated.
"Because I am a Principal, after all. If I have to ask a Professor for help with everything, what kind of prestige would I have?" Dumbledore said, shrugging.
"You didn't hide it from Severus in Potions and secretly tinker around, so why are you so coy when it comes to Alchemy?" Kayson said, speechless.
"Severus is different from you," Dumbledore transfigured a chair and sat down. "From the moment he first enrolled, his Potions has always been so extraordinary, so I naturally accepted his label as a Potions genius."
"But your Alchemy genius was suddenly thrust upon you, and now you're already on par with Nicolas Flamel. But perhaps because of our first meeting, I always see you as a... hmm... an impetuous boy who hasn't grown up."
Dumbledore said wistfully.
"I understand," Kayson nodded, which pleased Dumbledore, who expected Kayson to say something tender.
Kayson then directly spoke: "You're embarrassed, feeling it's shameful to be instantly surpassed in Alchemy by me, an Alchemy novice? Is that it?"
Dumbledore covered his face somewhat helplessly: "Why can't you say something nice?"
"I don't know why, Dumbledore, you are a very respectable person, but whenever I see you, I always want to find a way to make you look bad. As for why... I don't know." Kayson shrugged and walked directly towards the gargoyles.
He placed his hands on them, feeling the flow of the magic circuits within, and finally found the problem.
"It's a conflict between the pipeline I designed for you and the gargoyle's control circuit. A slight modification will fix it," Kayson said, and began.
As for how he began...
Alchemy, you know!
The power of Alchemy permeated the stone wall, slowly causing a slight deformation, finally separating the two circuits.
"Done!" Kayson said, clapping his hands.
Dumbledore slowly stood up, waved his wand, and reset a password for the gargoyle.
"Hmm... 'Jianbing Guozi' it is," Dumbledore said, then looked at Kayson: "Try it."
The latter nodded: "Jianbing Guozi."
The gargoyles slowly moved aside, clearing the path.
"So he wasn't stopping you from entering the office, he just didn't let you continue to modify the password?" Kayson said, realizing something as he watched the scene.
"Quite clearly... that's it," Dumbledore nodded. "Although the probability of the password being leaked is small, an unchanging password is very boring, isn't it?"
Kayson stood there, stroking his chin: "Whether the password is boring or not, I don't know... To be honest... Dumbledore... you're quite boring."
"Say what you like... Want to come in for a couple of drinks?" Dumbledore said, walking up the stairs and inviting him.
"Let's go!"
[Family, little brother is exhausted. It's 4 AM, and little brother has a bit of a headache.]
[I originally wanted to add another chapter, but little brother is... exhausted, really, the extra chapter failed.]
[Let's save it as a draft. I'm going out for a drink tomorrow, so I'll send out tomorrow's chapter... Hehehe!]
