The Magical Principles of Natural Philosophy at Hogwarts

Throughout January, Erwin continued the preliminary stage of magic text research.

The runes used for writing and reading are essentially the same as other words, but after being inscribed in a specific order and subjected to some processing, a certain kind of magic spell can be fixed and continue to work.

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

It is foreseeable that multiple runic execution codes can form an execution program. For example, adding several "powerful amplification" runic codes can make Erwin's thermal vest provide hundreds of times the heat, plus

With "Fire Blazing", a "Fire Protection" that protects oneself from high temperature damage, an ordinary thermal vest becomes a high-level combat item that can continuously release flames to burn nearby objects. If you don't want to damage the environment, you can also add something like "Target Lock"

" code.

Of course, this is an ideal situation. There are many issues that must be considered during actual production. For example, if the strength of the load-bearing material is not enough, additional magic text codes are needed to improve stability. Different magic text codes may also appear when executing

Unforeseen conflicts...

Although Erwin is still at the stage where he only understands the basic instructions, this does not prevent him from thinking about it.

In February and March, while Erwin was mastering some simple magic script execution codes one by one, he also began to try more advanced potion preparation. After all, if his own level was not up to par, what else would he use to teach Na?

Where's the power?

The chubby boy with a round face has silently mastered all the contents of the first-year potions tutorial. As long as he doesn't perform abnormally, he will have no problem passing Snape's test now. He is really talented.

The Diagon Alley Pharmacy provides a package of physical enhancement potions priced at over a thousand galleons. Erwin thinks they are profiteers and has no intention of taking care of their business even now that they have abundant funds. The Hogwarts Library told Erwin

Just like at home, the recipes for strengthening potions can be found in the library.

The price of a single ingredient is one-twentieth of the finished potion, which is a ridiculous ratio. As long as Erwin's refining success rate is higher than 5%, he will not lose money.

What's more, for wizards, the value of agility and endurance must be higher than strength, so balanced enhancement seems a bit stupid.

Another Friday, Erwin was preparing the Weasel potion in the secret camp in the Forbidden Forest. Neville walked in with a bruise at the corner of his eye.

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

Since publicly withdrawing from the Potions class, Slytherin students have often made trouble for the two of them. Although they were limited to petty troubles because of the presence of the professor, they never concealed their malice.

Neville shook his head, "It was Peeves. He hit me with his inkwell."

There are many ghosts in Hogwarts, and Peeves is the most troublesome one among them. He is a clown in colorful clothes who is keen on playing pranks and does not care who the target of the pranks is. People are often haunted by him.

As for delaying class time, most people had nothing to do with him. Even Percy, the prefect, could only threaten to find Bloody Barrow to punish him.

As for the students in the lower grades, they can only consider themselves unlucky when they encounter Peeves.

Erwin rarely wanders around the school, and he habitually casts the Disillusionment Curse on himself when he goes out at night, so he has never encountered Peeves alone.

He thought about it and found that his performance against Peeves would not be much better than Neville's.

Illusive ghosts are obviously not bound by the laws of mechanics, and nine-millimeter bullets can only hit the air.

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

Although he was used to Erwin asking strange questions, Flitwick was still quite surprised this time, "Why are you asking this question?" There was even a hint of nervousness in his tone.

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

"That's it." Flitwick looked obviously relieved.

He cleared his throat and leaned slightly closer, "Smart Erwin, haven't you noticed the difference between Peeves and other ghosts?"

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

And Peeves was able to grab an inkwell and hit Neville.

He understood, "Peeves is physical."

"That's right," Professor Flitwick nodded with satisfaction, "Peeves is not a ghost in the strict sense. He is not purely invisible, but more like a cloud. So I recommend the Hurricane Curse to you, even though it is

The content of "Standard Spell Level 5", but I think it shouldn't be too difficult for you."

Walking out of Flitwick's office, Erwin suddenly realized why the professor was so nervous just now. Ghosts are essentially souls that have lost their bodies, and the spells used to deal with souls...

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

Erwin suddenly became a little uneasy. He had killed people before. If it weren't for the dark wizard Marduk, he might not have realized the existence of the magical world. He didn't feel any regret or self-blame now, he was just acting in self-defense.

Marduk is a dark wizard who kills without blinking an eye. If he doesn't seize the slightest opportunity to counterattack when his opponent underestimates his enemy, he will have no choice but to let him slaughter him.

But the question is, was Marduk really completely wiped out?

Erwin had no doubt about this before. Marduk's body had been dissected and his death could not be more complete, but now he suddenly realized...

Where is the soul?

What if Marduk also became a ghost...

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

However, so much time had passed, Erwin could only convince himself that Marduk had not turned into a ghost - even if he turned into a ghost, it should not be a threat, as the ghost no longer has the ability to cast spells.

But there was still a thorn in his heart.

Mastering the hurricane spell is not difficult for Erwin. The effect is to summon a continuous violent airflow, which restricts the movement of humans or lighter creatures. Erwin spent a few days studying it.

It was found that the way this spell works is to create an air pressure difference with a temperature difference, and then add the effect of kinetic energy.

And isn’t the granting of kinetic energy his innate ability?

This spell suddenly opened a door for Erwin. He seemed to have never studied the mechanics of air in depth before.

In fact, he and Professor Stewart had already thought of this problem, but at that time they thought that in order to impart kinetic energy to the air, it must be microscopic to the molecular level. As a result, Erwin simply couldn't do it.

But now, with the help of the hurricane spell, Erwin discovered that the formed airflow could actually be sensed and then exerted a magical effect.

This made him enlightened.

In just half a day, Erwin can silently release the hurricane spell, and can flexibly control the power, direction and location of the airflow. He even "invented" two derivative spells - the eye of the wind spell to create a low air pressure.

The area thus forms a small whirlwind that does not last long, and a shock spell, which increases the power of the airflow and turns it into a small shock wave.

These spells did not actually improve Erwin's combat effectiveness, but he was still quite happy, because it meant that although magic can distort science at will, science can also react on magic, which will affect the most critical aspects of wizards.

An 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 also be used by first-year students. This is not difficult, just reduce the range and power. After all, it is just to deal with semi-virtual existences like Peeves.

The weakened version of the Hurricane Curse was named the Strong Wind Curse, and the power of the air flow produced was about the same as that of an electric fan turned to its maximum. Erwin taught it to Neville, "You can teach this spell to other students," he said: "

If one Strong Wind Charm is not enough, just add a few more, and two or three people should be able to stick Peeves on the wall."

When several first-year students get together and have the ability to fight back, Peeves should be more restrained.

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

"You can think I invented it." Erwin shrugged.

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

Time flows silently, and in the blink of an eye, more than half of the semester has passed, and Easter and spring break are coming soon, which means that the final exam is not far away.

Hermione had begun to get nervous, but with her grades she didn't have to worry about exams, so she transferred this nervous feeling to Harry and Ron. The two boys were unable to resist and complained endlessly. The Philosopher's Stone hidden in Hogwarts

It is still a common topic among them, but it is rarely mentioned now.

In the morning, Erwin went out for a morning jog as usual. Thanks to the potion he refined and the onset of puberty, his physical fitness had improved a lot. It was no longer a problem to put in some effort to run around the castle twice.

Erwin was a little surprised when he didn't see Hagrid when he passed 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 meet Erwin who was passing by.

greet.

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

During the second lap, Hagrid was still nowhere to be seen. Erwin noticed something was wrong. He walked over and felt a wave of heat before he even got close to the hut.

The doors and windows were closed. Erwin looked through the window and saw that the stove in the hut was burning very brightly. In the center of the flame was a dark giant egg, with scales clearly visible on the eggshell.

This is definitely not meant to be grilled and eaten.
