The Magical Principles of Natural Philosophy at Hogwarts

Throughout January, Erwin continued his research on runes in the primary stage.

The runes used for writing and reading are essentially the same as other scripts, but after inscriptions in a specific order and some processing, a certain kind of spell can be maintained and continue to function.

Erwin felt like typing a piece of executable code on the computer.As for who built this "computer" and why runes were chosen as the basic language, it's better not to think too much now.

It can be foreseen that multiple rune execution codes can constitute an execution program.For example, adding several "powerful booster" rune codes can make Erwin's thermal insulation vest provide hundreds of times the heat, plus "blazing flames" and "flame protection" to protect himself from high temperature damage. , the ordinary insulation vest becomes a high-level combat item that can continuously release flames to burn nearby.If you don't want to destroy the environment, you can also add code like "target locking".

Of course, this is an ideal situation. Many issues must be considered during actual production. For example, if the load-carrying material is not strong enough, additional rune codes are needed to improve stability. Different rune codes may also appear when executed. Unforeseen conflicts...

Although Erwin is still at the stage of only figuring out the basic instructions, this does not prevent him from thinking about it.

In February and March, while mastering some simple rune execution codes one by one, Erwin also began to try more advanced potion preparations. Wei?

That chubby boy with a round face has silently mastered all the content of the first-year potions course. As long as he doesn't perform abnormally, he can pass Snape's test now. His talent is really good.

The Diagon Alley Pharmacy offers a package of physical strengthening potions worth more than 1000 Galleons. Erwin thinks they are profiteers, and even if they have sufficient funds now, they have no idea of ​​taking care of their business. The Hogwarts Library told Erwin that it would be like Like home, the recipes for those strengthening potions can be found in the library.

The price of a single ingredient is one-twentieth of the finished medicine, which is an outrageous ratio. As long as Erwin's refining success rate is higher than 5.00%, he will not lose money.

What's more, for a wizard, the value of agility and endurance must be higher than that of strength, and the balance enhancement seems a bit stupid.

On another Friday, Erwin was concocting a weasel potion in the secret camp in the Forbidden Forest. Neville walked in with a bruise around the corner of his eye.

Erwin carefully introduced the emerald green medicinal solution into the test tube and sealed it. Seeing Neville's face, he frowned slightly, "Slytherin again?"

Since they blatantly quit the Potions class, the Slytherin students have often troubled the two of them. Although they only limited themselves to making small troubles because of the presence of the professor, they never concealed their malice.

Neville shook his head, "It's Peeves, he hit me with an ink bottle."

There are many ghosts in Hogwarts, and Peeves is the most troublesome one among them. He is a clown image in colorful clothes. He is keen on pranks and doesn't care who the prank is. As for the delay in class time, most people have nothing to do with him, even the prefect Percy can only threaten to find the bloody Baro to cure him.

As for the lower grade students, if they encounter Peeves, they can only consider themselves unlucky.

Erwin seldom wanders around the campus, and he habitually casts the Disillusionment Charm on himself when he goes out at night, so he has never encountered Peeves alone so far.

He imagined it for a while, and found that his performance in the face of Peeves should not be much better than Neville.

The illusory phantom is obviously not bound by the laws of mechanics, and the [-]mm bullet can only hit the air.

So when he went to report to Professor Flitwick on the progress of the week, Erwin asked him if he had any spells that could deal with ghosts.

Although I'm used to Erwin asking some weird questions, but this time Flitwick was quite surprised, "Why do you ask this question?" His tone was even a little nervous.

"I just want to figure out how to effectively deal with Peeves." Erwin was a little puzzled.

"That's it." Flitwick was visibly relieved.

He cleared his throat, and moved his body slightly closer, "Smart Erwin, don't you realize that Peeves is different from other ghosts?"

"Different?" Erwin was taken aback, and after some thought, he recalled the first day of school, when he touched the ghost secretly, and all he felt was nothingness.

And Peeves can grab the ink bottle and hit Neville.

He understood, "Peves has a body."

"That's right," Professor Flitwick nodded in satisfaction, "Strictly speaking, Peeves is not a ghost. He is not purely invisible, but more like a cloud of mist, so I recommend the Hurricane Curse to you, although it is The content of "Standard Spell Level Five", but I don't think it should be too difficult for you."

Walking out of Flitwick's office, Erwin suddenly realized why the professor was so nervous just now. The ghost is essentially a soul that has lost its body, and the spell to deal with the soul...

The most intuitive, the first of the three unforgivable curses, the death curse can directly obliterate the soul.

Erwin suddenly became a little uneasy. He had killed people. If it wasn't for the dark wizard Marduk, he might not have realized the existence of the magical world.He didn't have any regrets and remorse right now, he was just out of self-defense, Marduk was a murderous dark wizard, if he didn't seize the slightest chance that the opponent underestimated the enemy and fight back, then he could only let him be slaughtered.

But the question is, was Marduk really wiped out?

Before that, Erwin had no doubts about this. Marduk's body had been dissected, and the death couldn't be more complete, but now he suddenly realized...

What about the soul?

If Marduk turned into a ghost too...

No wonder dark wizards like to use Avada Kedavra, it is really a way to completely eliminate the enemy once and for all.

However, so much time has passed, Erwin can only convince himself that Marduk has not turned into a ghost-even if he turned into a ghost, it should not be a threat, and the ghost has no spellcasting ability.

But there was still a thorn in his heart.

It is not difficult for Erwin to master the Hurricane Curse. Its effect is to summon a continuous violent air current, which restricts the actions of humans or creatures with lower mass.Erwin spent a few days researching it, and found that the way this spell works is to create a difference in air pressure by temperature difference, and then add the effect of kinetic energy.

And isn't the endowment of kinetic energy his innate ability?

This spell suddenly opened a door for Erwin, the mechanics of air, which he didn't seem to have studied in depth before.

In fact, he and Professor Stewart had thought about this problem a long time ago, but at the time they believed that in order to impart kinetic energy to the air, it had to be microcosmic to the molecular level, but Erwin couldn't do it at all.

But now, with the help of the Hurricane Curse, Erwin discovered that the formed airflow could be sensed and then magically applied.

This made him suddenly enlightened.

In just half a day, Erwin could release the Hurricane Curse silently, and flexibly control the power, direction and location of the airflow, and even "invented" two derivative spells - the Eye of the Wind Curse, to create a low air pressure The area thus forms a small whirlwind with a short duration, as well as a shock spell, which turns it into a small shock wave by increasing the power of the airflow.

These spells did not actually improve Erwin's combat effectiveness, but he was still very happy, because it meant that although magic can distort science at will, science can also react to magic, and it will affect the most critical aspect of wizards. One ability is cognition.

Only by maintaining a clear understanding can we have the ability to learn, improve and achieve effective improvement.

The next thing to do is to simplify the Hurricane Curse so that it can be used by first-year students. This is not difficult, just weaken the range and power. After all, it is only to deal with the half-illusioned existence of Peeves.

The weakened version of the Hurricane Curse is named Strong Wind Curse, and the power of the airflow generated is about equal to that of an electric fan turned on at its maximum.Erwin taught it to Neville, "You can teach this spell to other students," he said, "If one Strong Wind spell is not enough, just get a few more, two or three people should be able to paste Peeves on the wall .”

When several first-year students got together and had the ability to fight back, Peeves should restrain himself a bit.

"Why have I never heard of such a spell?" Neville asked.

"You can take it as my invention." Erwin shrugged.

"Excellent." The round-faced boy said sincerely.

Time is passing silently. In a blink of an eye, half of the semester is over, and the Easter spring break is coming, which means that the final exam is not far away.

Hermione was already getting nervous, but with her grades, she didn't have to worry about the exam, so she passed on this nervous feeling to Harry and Ron. It is still their common topic, but it is rarely mentioned now.

In the morning, Erwin went out for a morning run as an exception. Thanks to the potion he refined and the onset of puberty, his physical fitness has improved a lot. It is no longer a problem to run around the castle twice with a little strength.

Erwin was a little surprised that he didn't see Hagrid when passing by the lake.Hagrid usually got up very early, because he had to prepare food to feed the magical animals he raised. At this time, he happened to say hello to Erwin who was passing by.

It's been like that since Erwin's first morning run.

On the second lap, Hagrid was still not seen. Erwin noticed something unusual. He walked over and felt a wave of heat before he got close to the hut.

The doors and windows were closed tightly. Erwin looked through the window and found that the stove in the hut was burning extremely hot. There was a huge black egg in the center of the flame, and the scale pattern could be clearly seen on the eggshell.

This is definitely not baked to eat.
