In this underground chamber, the only exit is the one leading to the ground.
In other words, the underground buildings of Hogwarts are not connected to each other. Perhaps the original design intention is not for people to be able to enter and exit at will. After all, these buildings essentially form a large magic circle.
The important thing is the circuit, which is just equipped with a maintenance room.
The walls and floors are difficult to destroy. Riddle couldn't do it before he was sixteen, and neither can Erwin now. Maybe Quasimodo can be released to try violent demolition? That would make too much noise.
It may even cause vibrations on the surface above, making it impossible not to detect it.
Furthermore, this is considered damage to Hogwarts itself. If it has any impact on the functionality of the castle itself, then it is really a big mistake.
It is impossible to say that Erwin is not interested in the secrets of Hogwarts itself. He does have the urge to explore it, but there is no need to be impatient.
He will stay at Hogwarts for several more years, and even if he graduates, he will most likely choose to stay at the school. During this period, he will have a lot of time.
Furthermore, this is Hogwarts after all, not some wilderness ruins. If you really want to explore it, you should get permission from Principal Dumbledore.
Erwin didn't think that as a principal, he wouldn't know what was underground in this castle.
A huge magic network circuit maintains the operation of the castle. Yes, the entire castle can indeed be regarded as a huge alchemical creation, and it is also a very valuable endogenous alchemical creation.
The so-called endogenous type means that it can generate magic power on its own. Endogenous items are relatively more advanced alchemical products. The Flamel Cabin falls into this category. Every folding and unfolding of it should consume a huge amount of magic power, but it never does.
Let Erwin feel a little burdened.
Quasimodo should have been an endogenous creation, but unfortunately his internal structure has aged, and now it must be charged by Erwin.
And those made by Erwin himself, whether they are armor rings, repulsion rings or magical firearms, are essentially non-endogenous alchemical products, requiring him to provide magic power for them. But because of his own blood, endogenous types
It is still non-endogenous type, so the difference is really not big for him.
Most wizards need to use their magic power carefully, because running out of magic power not only means that they can no longer release magic, but it will also make the wizard tired, weak, and even fall into a coma.
Although there is a potion like the Blood of the Red Dragon that can quickly replenish magic power, it is not easy to use in wizard duels because the potion itself will become the carrier of the opponent's spell.
Just imagine, when your magic power is exhausted and you take out a bottle of red dragon's blood and prepare to drink it, your opponent casts an explosive spell and turns the bottle of flammable potion in your hand directly into a Molotov cocktail...
That is truly an out-and-out tragedy.
Therefore, combat items that can be used by wizards must have basic counter-curse effects. Just potions are not enough. There must be potion bottles with anti-curse capabilities, otherwise they will become a boost to the enemy.
However, in the entire magic world, the number of magic items is not large, and the number of alchemists is very rare. It is difficult to make any piece of qualified combat equipment, such as robes with anti-spell effects or combat potion bottles.
It takes several months or even years, and production capacity is extremely limited.
The price has naturally gone up, and there are basically no public sales channels.
In addition to spell resistance, another criterion for qualified combat equipment is endogenous type, which does not occupy the wizard's own magic power. At least it should be energy-storage type or can be effective by consuming a specific material. This
Two types can be considered semi-endogenous.
And Erwin is a nouveau riche in terms of magic power, and he is still a nouveau riche who can print his own money, so there is almost no difference between endogenous and non-endogenous types for him. There are almost semi-industrialized people in Flamel's cabin.
A complete set of magic text engraving devices, so that he can complete the equipment preparation in half a year.
After realizing the code nature of magic text, Erwin's understanding of it naturally improved by leaps and bounds. His excellent talent and tool bonus brought excellent efficiency.
Of course, the things developed are basically only suitable for Erwin himself. Among others, only special cases like Lockhart, who has no magic power but cannot cast spells, regard it as a great treasure.
Returning to Hogwarts itself, the castle can be said to be integrated. Erwin guessed that the Pen of Acceptance and the Book of Admission, which are responsible for entering the student roster, are also in this magic network circuit.
And the source of all magic power may be...
Since it is impossible to find out for the time being, it is better not to make random guesses.
There is ample time.
A week later, Erwin came to the Hogwarts administrator's office again.
Filch's attitude towards Erwin has improved significantly. After his long-cherished wish was fulfilled, he became much calmer.
"I have to trouble you to take a nap for a while." Erwin handed over the bottle containing datura powder.
Filch didn't hesitate, inhaled the powder, then endured a coma spell and fell into shock.
Erwin gestured to the door, and Melanie walked in.
"Observe his physical condition." Erwin said, he was not good at this.
His understanding of flesh and blood life is definitely not as good as this female vampire.
Melanie stretched out her finger, and a light red energy thread shot out and submerged into Filch's sleeping body.
"The blood integration progress is normal and there are no problems." She said.
Erwin nodded and asked Melanie to leave. Her special nature should not be known to Filch.
After waking up Filch, the bald old man looked directly at Erwin for a moment, "Thank you, Mr. Frost." He suddenly said softly.
"Professor Dumbledore told me that you have made great contributions to Hogwarts, and this is the reward you deserve." Erwin gave a very normal response.
Filch's eyes were a little moist.
Weekly examinations continued until the end of March. Filch's physical condition tended to be stable, and he ultimately did not possess much magic power, which was about the level of a third grader.
Only a little better than the current Harry and Ron.
After all, he is already very old, and as the first-generation bloodline spreading agent, the Red Dragon Type I is not very powerful and has a lot of room for improvement.
But Filch himself seems to be very satisfied. He has finally been able to get a response after waving his wand in his life. What else can he hope for?
He even wanted to express his eagerness, but fortunately Erwin asked him to keep the secret temporarily in the name of Dumbledore, so Filch held back and did not let the whole school know that he suddenly had magic.
"I don't recommend that you invest in him anymore." Riddle said to Erwin: "Obviously, your potion has limited effect on him, and even if you give him more, it won't have a good effect. He
This kind of person can't hide any secrets in his heart, and he must show it off. It would be troublesome for him to have too strong magic power. It will not be easy to downplay our existence. Once someone with care is noticed, such as your Potions Professor, you will probably
Can't escape."
This suggestion made sense, and Erwin decided to adopt it. Filch had already proven that Red Dragon Type I was effective on humans. This potion is currently only prepared by Erwin himself, and the output is limited. It really shouldn't be wasted on Filch.
