The Magical Principles of Natural Philosophy at Hogwarts

If you just want to deal with conventional projectile gunpowder weapons, there are naturally many ways.

For example, it can prohibit the occurrence of nearby burning phenomena that do not involve magic power, so that gunpowder cannot ignite; or create a rust field to quickly scrap metal products; in extreme cases, you can even start directly from the weapon holder, lock nearby firearms, and then directly kill them.

The dead holder will naturally not be shot by firearms.

After dealing with Muggles for so many years, wizards should have at least summed up how to deal with small weapons.

But what Erwin was thinking about was the battle between two high-level vampires he saw at that time. Although it only lasted a few seconds, he was very impressed.

The three- to four-meter-long horny giant blade created by the perfect Melanie using blood magic was slashed at the speed of sound. How to defend against such a physical blow? The seventy-meter long one in the Romanian breeding farm

His big cousin, to what extent can he resist a claw attack or tail sweep?

As Erwin thought about it, he warned himself again not to be fooled by the female vampire's current appearance and attitude.

If there is such a super armor in Nico Flamel's legacy that has extremely high hardness, high toughness, excellent shock absorption and will not cause too much burden to the wearer, then Erwin's problem will naturally be solved, but unfortunately it will not

No.

Although a master alchemist who lived for more than six hundred years must have many wonderful collections, he would not keep them all in a small house.

So Erwin had to find a way on his own.

He really found a solution. He found a set of magic script codes in Flamel's collection of books that could construct a "repulsive force field".

The repulsive force field centered on itself exerts a repulsive force on any approaching object, causing it to slow down and deviate from its original trajectory. In theory, as long as the repulsive force is strong enough, it can be regarded as a rational shield to defend against any physical attack.

The question now is how to change the code to generate enough repulsion while at the same time engraving it on a ring.

Erwin had a hunch that the rebuke ring would be at least several times more difficult to make than the armor ring.

But he has plenty of time.

After writing to Madam Malkin's robe shop in Diagon Alley, Erwin learned a day later that there was currently a fabric on the market made of Yeti hair and South American giant spider silk, which could effectively protect against Muggle bullets.

The strongest clothing material allowed for sale.

It is lightweight, durable for storage, does not require much maintenance, and has good ductility. The only disadvantage is that it is expensive because it must be woven by hand.

After thinking for a while, Erwin spent a huge sum of eight hundred and twenty-two galleons to order two "blade protective linings" made of this fabric.

In the magical world, things will become easier as long as the money is in place. Three days later, Erwin received his order. Sabi also sent a small box with him. This was from Professor Stewart.

.

Inside the box is a black metal object.

Israeli mini Uzi submachine gun, brand new, equipped with five magazines, ready to fire immediately.

After receiving the express delivery, Erwin immediately started an experiment. He used hard-shell beetle powder and volcanic slug mucus to make a large ball of gel, then put a sharp blade protective lining on it and stood ten meters away.

Empty a magazine from the Uzi submachine gun.

There was no damage to the lining itself. Erwin peeled it off and saw a lot of scattered cracks on the gel, but they were not big, and the gel itself was not broken.

This blade protective lining absorbs most of the kinetic energy of the bullet, which means that it provides real protection, not just preventing bullets from penetrating.

Then its performance in defending against cold weapon strikes will inevitably be even better.

Of course, in the magical world, this can only be regarded as the most basic protection method, but after all, it can be purchased directly with Galleons, so it is still worth the money.

The issue of defense was put aside for the time being. The next step in improving his own combat effectiveness was the offense. Erwin asked Felwood to send him an Uzi submachine gun through Professor Stewart not just to test the performance of the blade's protective lining.

After the overall magic power reserve and magic power rate have been greatly improved, the revolver with only six rounds of ammunition should be eliminated.

There are many offensive magics. What should be considered is the output efficiency, that is, how to use the least amount of magic to achieve the highest attack effect.

So for the current Erwin, the cost-effectiveness of any offensive spell is definitely not as good as the grant of kinetic energy. This is his innate ability, and it is an unrivaled advantage without the need for a wand.

Using black magic requires enough malice, which will inevitably affect one's mental state in the long run, which Erwin is very resistant to.

What's more, it's not just the use of black magic that can cause destructive and harmful consequences. Due to the limited level of knowledge of the current wizarding society, it is believed that only black magic has great lethality.

But Erwin believed that given time, he could definitely make uranium-235 fission without any malice.

Of course, this mini Uzi is not used directly. Erwin disassembled it, removed the firing pin part, and then used the fully automatic forging tools in Lemay's cabin workshop to create a one-to-one replica. The materials used

It is a special version of high-strength alloy made by master alchemist.

At least on this planet, natural super metals such as mithril and fine gold do not exist, and magic cannot go beyond the periodic table of elements. Therefore, to wizards, the value of metallic materials is much lower than biological materials.

Of course, inscribing magic words on metal can make metal possess magical power, but that obviously no longer belongs to the category of "natural".

In fact, for Erwin's ability to impart kinetic energy, there is no correlation between the bullet fired and the style of the firearm itself. However, designing a firearm that is easy to hold, has a simple structure and is easy to replace accessories also requires very professional knowledge, mature imitation and

An extensively tested design will obviously be the best choice.

Erwin decided to make a weapon for himself, a weapon independent of the wand.

The gun chamber and barrel were ultimately made of keel, which could be more efficiently engraved with magic text. Currently, the two magic text codes that should be considered are powerful magic power transmission and electromagnetic acceleration.

The firearm itself must also be strengthened, and should at least have corrosion resistance, deformation resistance and disarm resistance.

The bullets should also be engraved with magic text, and the effects of the armor spell and the cutting spell should be coded in magic text, and then some effective fragments should be intercepted. The magic cancellation effect of the former can make the fired ammunition less susceptible to magic interference.

The latter can significantly improve penetration.

The idea is great, but I still don’t have a clue on how to implement it.

There were many things to do, and they were all very difficult. Erwin felt the pressure. After all, in addition to trying to make rebuke rings and magic weapons, he also had to practice a lot of magic spells. Now that he no longer had to worry about magic recovery,

He planned to learn all the practical spells he could find so that he would be able to deal with any environment.

Fortunately, he has a lot of time, really a lot of time, he is only a sophomore.

Having stayed in Flamel's cabin for several days, Erwin felt that he should at least respect the school's rules and regulations and go back to his dormitory to sleep.

Neville was very excited when he saw Erwin and told him about mandrake in herbal medicine class.

"Under the leaves are baby-shaped roots, which make a very unpleasant cry. I didn't expect to see such a magical thing with my own eyes..."

Erwin realized that he seemed to have missed classes that he shouldn't have. He completely forgot about the herbal medicine class when he was conducting experiments in Flamel's cabin.

There is no way for him to learn on his own in advance the cultivation of specific herbs, not to mention that mandrake is a very advanced and cherished herb. Its mature juice is an important raw material for various antidotes and can be used to calm most curses and demons.

Damage caused by drugs.

If we want to say who is the best producer in Hogwarts, it must be Professor Sprout. Her greenhouse can cultivate many high-value herbs in batches.

But having said that, Mandrake is both of high value and dangerous. Is it really appropriate for second-year students to participate in the cultivation process...

No matter what, Erwin still has to apologize to Professor Sprout.

After a good night's sleep, Erwin concentrated on his course content the next day, then went to the library, and the day passed like this.

At night, Erwin was lying in bed with his consciousness sinking, half asleep and half awake, about to fall into a deep sleep, but he suddenly sensed something, sat up suddenly, grabbed the wand beside the pillow and pointed it at the black shadow beside the bed.

"It's me." Melanie whispered.

"What are you going to do?" Erwin still didn't relax his vigilance.

A beautiful little girl visited the boys' dormitory at night, and things seemed to be going in a strange direction, but Erwin would never forget that the girl in front of him was a vampire who had lived for who knows how many years.

"Don't make a sound." Melanie put her slender hand on her lips, "Use your stealth spell and follow me. She's not far away yet."

"She? Who?" Erwin was confused.

However, Melanie didn't seem to intend to explain too much. Her body turned into a faint black shadow. It seemed that although most of her power was imprisoned, she could still use some small means.

Erwin cast the Four Stealth Curses on himself and quietly left Gryffindor Tower with Melanie.

Then they saw a red-haired girl in front of them.

Erwin recalled that she was Ginny, the first-year freshman, the youngest girl in the Weasley family, and she usually seemed insignificant.

"Why are we following her?" Erwin asked Melanie.

"Shh-"

From Erwin's point of view, it was quite normal to wander around the school without sleeping at night, but it was a bit surprising that Ginny, a first-year girl, dared to do this.

What surprised him even more was that Ginny did not walk towards the library, but towards the main building of the castle, and finally entered the... bathroom on the second floor.

This female vampire took me to watch a girl use the bathroom? Erwin thought it was a bit funny.

But is it necessary to go so far to solve a physical problem? Could it be that the toilet in the Gryffindor girls' dormitory is blocked?
