The Magical Principles of Natural Philosophy at Hogwarts

Neville also woke up at this time, and under his expectant gaze, Erwin opened the not-so-exquisitely packaged gift box he gave him.

It is a piece of fire scale bulb, which can be regarded as a medium-level potion material. It can be used in many potions, including the blood of the red dragon.

It is a practical item, and by the standards of a gift from a child, it is quite rare.

For such a large piece of fire pattern bulb, the selling price is about fifteen or six silver Sickles.

"I cultivated this. I used more than an ounce of seeds, but it only grew into such a piece." Neville was a little embarrassed, "Professor Sprout helped me a lot, and I feel that I wasted a lot of resources , but she doesn't care."

In this case, the value of this gift cannot be measured by Garen. In comparison, the gift given by Erwin seems a bit perfunctory. The Christmas gifts he gave to these classmates who are familiar with him are all Although the value of the books, snacks and toys purchased uniformly is not low, they basically don't spend much thought.

"Thank you." Erwin said sincerely.

Neville was very happy, showing a silly smile. He was a little uneasy because he was worried that this gift was inappropriate, but now he is completely relieved.

The only gift left was an authoritative document recording modern supernatural phenomena in England from Professor Stewart. Although it was described from the perspective of Muggles, it still had a certain reference value.

Since there is no immediate family member other than Uncle Felwood, these are the only Christmas presents for Erwin. For someone who is easily sentimental, it may feel a little desolate at this time.

But Erwin certainly didn't feel that way.

On Christmas morning, every staying Hogwarts student wakes up to find their Christmas presents piled up by their bed.Of course, the gifts don't grow legs on their own. There are a group of couriers who try their best not to show their presence to deliver them.

Erwin remembered the little gift on the table before dinner yesterday.

The students usually only saw the administrator Filch cleaning, but even an official wizard would be exhausted if he was responsible for cleaning the entire castle, let alone Filch, a squib.In fact, the operation of the entire school is basically maintained by a group of house elves.

They clean, cook, carry, and do everything else.Not everything can be solved directly by wizards with magic. These elves are like screws, low-key but important.

They have obeyed Hogwarts for generations and are an integral part of the school.

So, would they be willing to take the initiative to defend Hogwarts?

Erwin was a little curious.

Walking out of Gryffindor Tower and going to the Great Hall for breakfast, what is the difference between Christmas and an ordinary day?It is more deserted, most of the students have gone home.

In the process of quickly filling their stomachs, Harry's trio also came to the table, "Now that the compound soup has been prepared, how are you going to use it?" Erwin asked.

"I tend to use it during the Christmas holidays, when it's the least noticeable." Hermione said, pouring herself a cup of hot milk, "We can find a way to get rid of Crabbe and Goyle, so haha Leigh and Ron can pretend to be them and approach Malfoy, and I can pretend to be Millicent Borst, who has left school, for a short time, so I should not be noticed."

She's pretty much the brains of the trio right now.

The "left hand" and "right hand", that is, Harry and Ron, do not seem to dispute this.

"After all, this is considered a violation of school rules, and it has been a long time since the last attack, are you sure you want to test Malfoy?" Erwin asked with narrowed eyes.

The basilisk is dead, and there is no real threat to the school.Being petrified is just a cat. The time span of nearly two months has diluted the fear brought about by the rumors of the secret room, and not many people take it seriously.

Of course, Erwin, who contributed to all this, would not take the initiative to boast of his "achievements".

Harry was silent for a while, and it was true that he hadn't heard that whisper for a long time, but he still made up his mind, "At least we need to find out what relationship Dobby has with Malfoy."

After being injured in the last Quidditch match, Harry already had a guess in this regard after being instructed by Erwin.

The blood of adventure burns in his veins, and he longs to know the truth.

"Then I can only remind you to pay attention to your speaking skills, don't reveal your truth too early." Erwin shrugged.

All along, he hadn't planned to actively participate in the trio's adventure, because he suspected they had been in Snape's sight.

In this case, taking the initiative to get close to him would probably cause fire. After all, he had modified Malfoy's memory, and it was impossible for Snape not to notice it. He must really want to catch the culprit.

What's more, Erwin didn't think Brother Yan would know much. Who would tell his eleven or twelve-year-old son the whole plan when he was plotting?

For the plan of the three of Harry, he only provided limited help, and then got a little reward. Even if Snape pursued it, the big deal would be to hand over the bottle of Polyjuice Potion.

After bidding farewell to the three little ones, Erwin went down to the first floor, turned around and entered a secret passage.

At the end of the secret passage, before a wall with a strange snake pattern, he stopped.

Taking out the wand, drawing in the air, one after another, glowing runes appeared on the wall until there were as many as fifteen.

This is the entrance to the secret passage leading to the underground secret chamber. Originally, it required the blood of Slytherin to open it. Later, Riddle changed it to only need to speak specific syllables in Parseltongue. Now it is Erwin's turn to control the secret chamber. Naturally, the unlock key must also be changed.

With Riddle's cooperation, it is not difficult to do this.Erwin set a set of [-]-digit passwords, which is quite safe.

Fifteen runes were arranged in a certain order to form a circle, and then the light went out, and the wall split to both sides, revealing the passage.

Erwin's footsteps echoed below.

Going down to the secret chamber, he raised his wand again, and the luminous stones in the mouths of all the giant snake statues lit up, providing illumination.

In the corner of the secret room is a potion table, and Erwin put the diary on it first.

A phantom appeared, which changed from blurred to solid in a few seconds. It was Riddle, and he could display his image unscrupulously in this secret room.

"What now?" he asked gracefully.

"Create a Mana Awakening Potion," Erwin said.

The primary purpose is to master the brewing process of this potion, and then consider its efficacy and other combinations.

Yesterday Lockhart sent all the medicinal materials to Erwin, and he worked wholeheartedly and was very efficient.

"Have you discovered it too?" Riddle's eyes became meaningful, "The pursuit of more powerful magic power is the essential pursuit of every wizard, because we don't have to worry about basic survival needs, the only thing we need is power, powerful, power over others."

"Your statement is not wrong." Erwin's reaction was quite flat.

"Magic Awakening Potion can stimulate the potential of the bloodline, which is very important for young wizards in their growing period, but the potion provided by this school can only meet the most basic requirements. If it is just a mediocre mediocrity, then a bottle of magic power every six months Awakening is enough, but even a little bit of talent and ambition is not enough."

Riddle looked directly at Erwin, and continued slowly: "Mastering the making of magic awakening potion, you can not only meet your own needs, but also provide it to others, so that they don't have to spend a lot of money to buy extra potions. , so that you have a lot of friends, you can gather some people around you, the friendship maintained by the relationship of interests is the most reliable, isn't it?"

"Stop talking nonsense." Erwin had a cold face, but he didn't seem to deny this statement.

The curvature of Riddle's mouth became more and more obvious, "Don't worry, I will help you. Excellent people like us deserve excellent treatment. We are natural leaders, so we should stand on the heads of mediocrity."

"Now you can tell me all the key points in the preparation process." Erwin reminded him.

"Well, in fact, the process of brewing potions is not difficult." Riddle shrugged, "As I told you a few days ago, the biggest difficulty is actually in the processing of materials. The more complicated the potion, The requirements for the state of raw materials are more stringent, powdery, pasty, liquid, concentration, viscosity, and temperature all have different requirements, and there is nothing wrong with it.”

The most troublesome part of making potions is to process the raw materials to meet the corresponding requirements, which is very similar to cooking.

"The processing of raw materials may be complicated, and it may take a long time. It is common to cook for two or three months in a row. Don't expect to finish it in one afternoon." Riddle said.

Erwin didn't answer, he stretched out his hand, and the black cube formed by the collapse of LeMay's cabin began to rotate and expand to a size of one meter long.

A rift opened, and Erwin took out bottles and jars from inside.

Riddle's complexion changed one after another, those bottles and jars were filled with processed raw materials - and he had only told Erwin about the processing requirements of those raw materials two days ago, and Erwin had only received the materials a day ago.

He reconfirmed, that's right, they were all processed according to strict requirements, and this kind of workload would take at least a week for even the most skilled pharmacist to complete.

"How did you do it?" He couldn't help asking Erwin, a little gaffe for the first time.
