Dumbledore? He knows nothing about MC alchemy.

After doing all this, Kaisen returned to the principal's office. At this moment, the principal's office was a true paradise on earth, the only place where Kaisen could catch his breath.

"Have you figured out that magic?" Kaisen sat tiredly in the chair, looking like he was only one step away from burning out.

"It's still a little bit short, but now we know the principle. This should be Tom's work." Dumbledore said quietly.

"Yeah, you can tell. After all, Severus' arm looks hot." Kaisen nodded and looked at Snape's forearm which was constantly emitting steam.

"Is this thing so exaggerated?" Kaisen asked in surprise.

"That's what the Dark Lord does when he's angry enough, but obviously his anger isn't directed at me," Snape explained with a shrug.

As for the other little wizards in the office, they had already taken the initiative to undertake the task of decorating the corners. At this time, they were ready for a sudden enlightenment from the back of their heads that everything was gone.

Although it is an open secret in the wizarding world that Professor Snape used to be a Death Eater, isn't it a bit too much that in the second week of Voldemort's Revenge, Professor Snape is still a Death Eater?

What’s even more outrageous is that Professor Dumbledore knows about this!

This is even more of a secret that goes far beyond the heavens. In the face of such a secret that goes far beyond the heavens, it is not a problem to have one's memory erased. It really is not a problem.

"Of course I know it's Voldemort's method. What's the principle behind this, and how can it be solved?"

"Hogwarts' original protective magic can prevent anyone in Hogwarts from being affected by magic and curses outside the school. The current situation can only be said to be a flaw in Hogwarts' protective magic." Dumbledore explained.

"It could even be worse. This large-scale impact on the entire school may be due to the contamination of Hogwarts' own defensive magic. Otherwise, to be honest, Voldemort cast this large-scale emotion-affecting magic on hundreds of young wizards in Hogwarts." Grindelwald added.

The beautiful secondary creation of my old friend [Kid’s Daily Meals], well, it is still stable, and deserves praise... The author needs gifts!

Chapter 429 Vertical Mining Method!

Kaisen took out a small wine flask from his arms and drank it all in one gulp. Then he waved his hand and a bottle of white wine floated seamlessly from the wine cabinet in the principal's office. After filling the wine flask, he blew directly into the bottle.

"How do we solve this? Do we need to go to a specific place or can we do it in the headmaster's office?" He looked at Dumbledore and asked.

"Go to the Room of Requirement and ask it to take you there," said Dumbledore.

"Can I solve the problem by myself?" Kaisen said as he stood up and stretched his waist hard.

"No spell, no matter how powerful, can remain constant for hundreds of years. Therefore, Hogwarts' defensive magic is continuously emanated from the core of Hogwarts by alchemical modules, which eventually spread throughout Hogwarts. You are an expert in this area," Dumbledore explained. "As for us, we will monitor the entire Hogwarts from here to ensure that Tom and his companions do not take advantage of the situation and sneak in."

As Dumbledore spoke, he looked at a piece of parchment in front of him. On it was a map. If Sirius, Lupin, or the Weasley twins were here, they would all see that this was the Marauder's Map.

"Okay." Kaisen nodded, took out his netherite sword and teleported directly to the eighth floor of Hogwarts, opposite the ugly tapestry.

Kaisen stood in the corridor and first cleared most of the cobwebs with his sword, then began to walk.

"I need to fix the defenses of Hogwarts. I need to fix the defenses of Hogwarts. I need to fix the defenses of Hogwarts."

He kept repeating this sentence in his heart, and soon a door suddenly appeared in front of him.

He breathed a sigh of relief. The Room of Requirement was still useful and had not been contaminated along with the protective magic of Hogwarts.

He opened the door, but it was not a proper room like when he went through the Room of Requirement to find Slytherin's Chamber of Secrets, but a dark place where he could not tell what was inside.

Kaisen yawned and was about to step in when he suddenly paused, then threw the netherite sword in his hand in.

Following a series of strange and ear-piercing sounds, Kaisen could clearly feel that the netherite sword he had just created had turned into a pile of debris.

"As expected, even the defensive magic of Hogwarts can be contaminated, so why can't the Room of Requirement be contaminated... But the magic of Hogwarts is really strong enough that even a netherite sword can tear it apart." Kaisen murmured and took two steps back. Then, after the door disappeared, he put up a sign next to it to let other people who knew about the Room of Requirement know that this room is now extremely dangerous.

After returning to the principal's office, Kaisen said, "The Room of Requirement has been contaminated and is now inaccessible. Do you know the true location of that room? Or is that room the actual Room of Requirement?"

"That room is a completely different one. I don't know where it is, but it's definitely not the Room of Requirement," Dumbledore explained.

Hermione sat weakly on the windowsill, her hands shaking nervously. Now she was truly panicking.

She had actually had direct or indirect contact with Voldemort before, but Voldemort at that time always targeted individuals, and Voldemort at that time was also extremely weak and not really a scary person.

Even though the entire magical community was terrified of Voldemort, Hermione herself still had no fear of this name.

Because she more or less knew too many of Voldemort's moments of failure.

Until now, Hermione truly felt the fear that the natives of other magical societies had towards Voldemort.

This is the suffocating feeling of being persecuted at any time and anywhere, and having no solution when a crisis occurs and can only wait for things to get worse.

Moreover, Kaysen, who had truly repelled Voldemort, and Dumbledore, the only person Voldemort feared, were both helpless against him...

"What's with that expression on your face?" Clay couldn't help but ask as he saw Hermione's expression becoming increasingly worse and weirder.

"Fear." Hermione swallowed and said simply.

"Are you afraid that Professor Kaysen can't find the alchemy room? And can't solve the current problem?" Clay accurately analyzed the nature of Hermione's fear.

The latter nodded: "Don't you have that feeling?"

Clay touched his chin and said, "I've learned a little bit of Professor Kaisen's tricks, but I think there should be other ways to use them, such as in this situation."

Hermione didn't quite understand what Clay meant, but soon Kaisen's actions explained to her what the method was.

Meanwhile, Kaisen took out a small wooden axe and knocked on the upper northeast corner and lower southwest corner of Dumbledore's desk. Then he knocked on it casually with the small wooden axe again, and the entire solid wood desk instantly became crystal clear glass.

"The theory works! Let's start the practice!" Kaisen nodded slowly, then he appeared in the upper northeast corner of Hogwarts, pointed with a small wooden axe, and then started digging down with a shovel in the lower southwest until he reached the bottom of the entire foundation, and pointed again with the small wooden axe.

Finally, it was still the familiar knock.

Everyone who was waiting in the office suddenly saw that the entire castle had turned into shimmering glass. For example, Hermione who was in the headmaster's office could even see Harry and the other two sleeping in the Gryffindor Tower not far away.

"Is this how Professor Kaysen solves problems?" Hermione said in disbelief.

"Obviously," Clay said.

After the castle became glass, the entire castle looked like a 3D design drawing in the eyes of Kaisen, who specialized in civil engineering.

Kaisen quickly found an underground secret room more than ten meters below the auditorium, where a huge alchemy module was vaguely floating.

Kaisen looked around casually and found that there was no passage that humans could enter.

"Well, I'll fight alongside you again, old buddy...vertical mining method!" Kaisen said as he appeared directly in the auditorium, found a corner, pulled open the carpet and started digging with his hands.

With the sound of "dong dong dong" incessantly heard, more than ten seconds later, Kaisen fell directly into this huge secret room. The last landing on the water was extremely elegant and perfect!

He looked up and could only vaguely see the outline of the auditorium. Because the stones that originally served as the foundation had become crisscrossing glass, the details were a little unclear, not to mention other places, such as the principal's office or the tower dormitory.

Chapter 430 Vanishing Cabinet

Just as he looked up at the huge alchemical module floating in the air in the center of the secret room, a corner behind Kaisen slowly flashed with shimmering light effects.

Two Death Eater dogs sneaked out from under the double concealment of the Invisibility Cloak and the Disillusionment Charm.

They looked at Kaisen who was studying the alchemy module not far away and looked at each other. After confirming their eyes, one of them waved his wand frantically, and the dense armor on his body solidified his protective magic as if it were solid.

The other one starts the Avada's accumulation of power by confirming the eyes and preaching.

After all, the two of them were high-ranking talents in the Death Eaters' team, and naturally they knew how terrifying Kaisen was. Even their master had suffered a great loss at his hands, so it didn't matter how careful they were.

Just when the two infantry tanks were about to touch the back of Kaisen's head, the latter suddenly turned around and slapped the head of the Death Eater who was acting as a shield in front of him.

In an instant, the armor that had been solid as a body became as if it were made of paper, and the Death Eater's head was directly smashed into a Chaoshan beef ball by this force.

The Death Eater behind him who was charging the Killing Curse was stunned by the situation and released the Killing Curse directly.

With a terrifying sound of breaking through the air, the killing curse missed perfectly.

The Death Eater's heart was pierced by Kaisen's mechanical arm early on.

"These two idiots, they put such a big disappearing cabinet in the corner, do they think I'm blind?" Kaisen wiped the blood off his hands with a handkerchief speechlessly and said helplessly. After cleaning himself, he turned around and looked at the huge alchemy module again.

It has to be said that the wisdom of the four giants of Hogwarts can be said to be endless. The alchemy module is not just an ordinary stone tablet engraved with alchemical runes.

It is a very standard regular dodecahedron Rubik's Cube, each small piece of which has a specific alchemical rune, and each face is a completely different protective magic against Hogwarts. The only difference is how the alchemical runes on this face are arranged and combined.

"Ancient alchemical spell arrangement... Fortunately, it was me who came. If it was Dumbledore, he would know nothing about alchemy." Kaisen murmured and began to study the entire alchemy module. Although he knew how to repair this alchemy module, it would definitely not take time.

Therefore, rather than repairing it, the most urgent task is to stop it and prevent this alchemy module from continuing to affect Hogwarts.

Thinking of this, Kaisen flew directly above the module. One of the modules directly above was emitting a steady stream of magic power, which was directly transmitted to the auditorium. The ceiling of the auditorium then absorbed it and finally supplied it to the entire Hogwarts Castle.

The solution is simple. Either destroy the auditorium so that the alchemy module cannot gather magic. Then the function of the entire alchemy module will be greatly reduced. At best, the smell of gunpowder in Hogwarts will be a little stronger, but it has always been a bit unclear.

Or destroy the ceiling of the auditorium, so that this strange magic will only gather in the auditorium, and at most other places near the auditorium, and will not spread to the entire castle.

Of course, the shortcomings are also very obvious.

Like, the effects of this magic will be so severe, so severe that if people walk into the auditorium, they'll either get their brains blown out, or just treat themselves to an Avatar melon.

Obviously, neither solution is very good, and as the alchemy professor who knows the most about alchemy at Hogwarts, I will certainly have a more awesome solution.

He slowly took out a name tag and slapped it on the alchemy module.

【Alchemy Module】

Damaged Alchemy Module

As the strange light on the alchemy module slowly dissipated, the entire Hogwarts returned to normal in an instant. Dumbledore and his companions who were watching closely in the headmaster's office were the least aware of it.

"He succeeded... No, not yet. He didn't solve the pollution, but directly stopped the protective magic of Hogwarts." Dumbledore's mood was full of ups and downs.

The whole person was confused and forced.

"But at least no one in the whole of Hogwarts will free-fall onto the grass anymore, right?" said Hermione.

"That's right, as long as you don't get carried away."

Dumbledore said teasingly, looking at Hermione.

"Oh, I will."

Of course there are others, such as the professors who fought in the corridors of Hogwarts and were then ruthlessly wrapped in spider webs by Kaisen. Looking at the colleagues who had fought with them a few minutes ago, they were now only embarrassed.

"When do we have to leave?"

"Don't know? Once one of them completely resolves today's mess, Kaisen should come to rescue us."

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

All this has nothing to do with Kaisen, because he has now fallen down and undone his previous operation of using the Creator to modify the materials of Hogwarts.

Hogwarts turned from transparent back into stone, and Kaisen was finally able to calm down and concentrate on studying the Rubik's Cube in front of him.
