The Magical Principles of Natural Philosophy at Hogwarts

In this underground secret room, 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 intention of the design 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, but it is only equipped with a maintenance room.

The walls and the ground are very difficult to destroy. Riddle couldn't do it before the age of 16, so Irwin can't do it now.Maybe Quasimodo can be released to try violent demolition?That kind of movement is too big, and it may even cause vibrations on the surface above, and it is impossible not to be discovered. m.biqmgè

Furthermore, this is also a damage to Hogwarts itself. If it has any impact on the functionality of the castle itself, then it would be 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, but there is no need to be impatient.

He will stay at Hogwarts for a few more years, and even if he graduates, he will most likely choose to stay in school, during which he will have a lot of time.

Furthermore, this is Hogwarts after all, not some wilderness relic, and if you really want to explore it, you should get the permission of the headmaster Dumbledore.

Erwin didn't think that as the principal, he would not know what was underground in the castle.

A huge magic net circuit maintains the operation of the castle. Yes, the whole castle can indeed be regarded as a huge alchemy creation, and it is also a very valuable endogenous alchemy creation.

The so-called endogenous type refers to the ability to generate magic power on its own. Endogenous items are relatively more advanced alchemy products. The LeMay Cabin belongs to this type. Every time it is folded and unfolded, it should consume a huge amount of magic power, but it has never Let Erwin feel a little burden.

Quasimodo should also be an endogenous creation, but unfortunately his internal structure has aged, and now he must be charged by Erwin.

And those made by Erwin himself, whether it is the armor ring, the ring of strong reprimand, or the rune guns, are essentially non-endogenous alchemy products, and he needs to provide magic power for them.But because of his own blood, the difference between the endogenous type and the non-endogenous type is really not that big for him.

The vast majority of wizards need to use their magic power carefully and carefully, because the exhaustion of magic power not only means that they can no longer release magic, but also make the wizard tired, weak, and even fall into a coma.

Although there are potions such as the Red Dragon Blood Potion that can quickly replenish mana, this thing is not easy to use in wizard duels, because the potion itself will become the carrier of the opponent's curse.

Just imagine, when your magic power is exhausted and you take out a bottle of Red Dragon Blood to drink, your opponent casts a bursting spell that turns the bottle of flammable potion in your hand into a Molotov cocktail...

That was truly tragic.

Therefore, the combat items that can be used by wizards must have the basic anti-spell effect. It is not enough to have potions, but there must be a potion bottle with anti-spell ability, otherwise it will become a boost for the enemy.

However, in the entire magic world, the number of rune items is not too large, and the number of alchemists is very rare. To make any piece of qualified combat equipment, such as a robe with an anti-spell effect or a battle potion bottle, It takes months or even years, and the production capacity is extremely limited.

The price will naturally rise, and there will be basically no public sales channels.

In addition to spell resistance, another standard for qualified combat equipment is endogenous type, which will not take up the magic power of the wizard itself, at least it should be energy storage type or can be used by consuming certain materials. Two can be considered semi-endogenous type.

And Erwin is an upstart in terms of magic power, and he is still an upstart who can print money by himself, so there is almost no difference between endogenous and non-endogenous types for him.In LeMay's hut, there is almost a semi-industrial set of rune engraving devices, so that he can complete his own equipment preparation in half a year.

After realizing the code nature of the rune, Erwin's understanding of it naturally improved by leaps and bounds. Excellent talent and tool bonuses brought about excellent efficiency.

Of course, the things developed are basically only suitable for Erwin himself. Among others, Lockhart is a special case who has no magic power but can't cast spells, so he will regard it as an incredible treasure.

Going back to Hogwarts itself, the castle can be said to be a seamless one. Erwin guessed that the pen of acceptance and the book of admission responsible for entering the student roster are also in this magic net circuit.

And the source of all magic power, perhaps...

Since it's impossible to find it for the time being, it's better not to guess at will.

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 a lot calmer.

"I have to trouble you to sleep for a while." Erwin handed over the bottle containing the mandala powder.

Without hesitation, Filch inhaled the powder, then suffered the stun spell, and fell into shock.

Erwin gestured to the door, and Melanie walked in.

"Observe his physical condition." Erwin said, he is 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 thread of energy shot out, sinking into Filch's sleeping body.

"The progress of blood integration is normal and there is no problem," she said.

Erwin nodded and told Melanie to leave. Filch should not have known about her specialness.

After waking Filch, the bald old man looked directly at Erwin for a moment. "Thank you, Mr. Frost," he said suddenly and softly.

"Professor Dumbledore told me that you have made great contributions to Hogwarts, and this is what you deserve." Erwin responded very normally.

Filch's eyes were a little moist.

Weekly inspections continued until the end of March. Filch's physical condition tended to be stable. In the end, he didn't have much magic power, which was about the level of a third grader.

Only slightly better than the current Harry and Ron.

After all, he is already very old, and as the first-generation bloodline diffusion agent, Chilong I, its efficacy can be said to be not that strong, and there is a lot of room for improvement.

But Filch himself seemed satisfied enough that he could finally get a response after waving his wand for the first time in his life, so what more could he hope for?

He even wanted to show it urgently. Fortunately, Erwin asked him to keep it a secret temporarily in the name of Dumbledore. Filch held back and did not let the whole school know that he suddenly had magic.

"I don't recommend you to invest in him." 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. Letting him have too much magic power is actually troublesome, and it's not easy to dilute our existence. Can't escape."

The suggestion made sense, and Erwin decided to take it.Filch has already proved that Red Dragon Type I is effective for humans. Currently, only Erwin has prepared this potion himself, and the production is limited. It really shouldn't be wasted on Filch.
