The Magical Principles of Natural Philosophy at Hogwarts

Neville also woke up at this time, and under his expectant eyes, Erwin opened the not-so-elegantly wrapped gift box he sent.

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

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

Such a large piece of fire-patterned bulb would cost about fifteen or six silver coins.

"I cultivated this. I used more than an ounce of seeds, but it only grew like this." Neville was a little embarrassed. "Professor Sprout helped me a lot. I feel like I wasted a lot of resources."

, but she didn’t care.”

In this case, the value of this gift cannot be measured in galleons. In comparison, the gifts given by Erwin even seem 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 together is not low, little thought was put into them.

"Thank you." Erwin said sincerely.

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

The only remaining gift was an authoritative document recording supernatural phenomena in modern England given by Professor Stewart. Although it was described from a Muggle perspective, it still had certain reference value.

Since he has no direct relatives except for Felwood's uncle, Erwin only has these Christmas gifts. For someone who is easily sentimental, he might feel a little desolate at this time.

But Erwin certainly didn't feel that way.

On Christmas morning, every remaining Hogwarts student will wake up to find their Christmas gifts piled in front of their bed. The gifts certainly don't grow on their own, and there are a group of couriers who try their best not to show their presence.

Delivering them.

Erwin thought of the small gifts on the table before yesterday's dinner.

Students usually only see the administrator Filch cleaning the house, but even an official wizard who is responsible for the cleaning work of the entire castle will be very tired, let alone Filch, a squib. In fact, the entire school

The operation is basically maintained by a group of house elves.

They clean, cook, carry, and are responsible for all miscellaneous matters. Not everything can be solved directly by wizards and magic. These elves are like screws, low-key but important.

They have obeyed Hogwarts for generations and are an indispensable part of this school.

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

Erwin was a little curious.

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

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

"I tend to use it during the Christmas holidays. This time is the least likely to attract attention." Hermione said, pouring herself a cup of hot milk, "We can find a way to separate Crabbe and Goyle, so haha

Leigh and Ron will be able to impersonate themselves to get close to Malfoy, and I'll be impersonating Millicent Bosted, who has left school, for a short time, so I shouldn't be noticed."

She is now very much the brains of the trio.

The "left hand" and the "right hand", that is, Harry and Ron, don't seem to have any objection to 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 still want to test Malfoy?" Erwin asked, squinting his eyes.

The basilisk is dead, and there is no real threat to this school. It is just a cat that was petrified. The time span of nearly two months has diluted the fear caused by the rumors of the secret room, and not many people still regard it as a real one.

Something happened.

And Erwin, who facilitated all of this, would certainly not take the initiative to boast of his "accomplishments."

Harry was silent for a while. He had indeed not heard that kind of whisper for a long time, but he still made up his mind, "At least we have to find out what the relationship between Dobby and Malfoy is."

After being injured in the last Quidditch match, Harry already had this suspicion after being prompted by Erwin.

The blood of adventure burned in his veins, and he longed to know the truth.

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

From the beginning to the end, he had no intention of actively participating in the trio's adventure because he suspected that they had been under Snape's sight.

Under such circumstances, taking the initiative to get involved would probably lead to anger. After all, he had modified Malfoy's memory, and Snape could not have failed to notice it. He would definitely want to catch the perpetrator.

What's more, Erwin doesn't think his classmates know much. Who would tell their eleven or twelve-year-old son the full plan when they engage in conspiracy?

For the plan of Harry and the three of them, he only provided limited help and received a little reward. Even if Snape pursued him, the worst he could do was 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, in front of a wall with a strange snake-like pattern, he stopped.

He took out his wand and drew in the air, one after another, glowing runes appeared on the wall, until there were fifteen.

This is the entrance to the secret passage leading to the underground secret chamber. It originally 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, you also need to change the opening key.

With Riddle's cooperation, it is not difficult to do this. Erwin set a fifteen-digit password, which is considered very safe.

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

Erwin's footsteps echoed below.

Going down to the secret room, 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 was a potion table, and Erwin put the diary on it first.

A shadow appeared, turning from blurry to solid in a few seconds. It was Riddle. In this secret room, he could show his image unscrupulously.

"What to do now?" he asked gracefully.

"Make a magic awakening potion." Erwin said.

The first purpose is to master the brewing process of this potion, and then consider its medicinal effects and other combinations.

Lockhart sent all the medicinal materials to Erwin yesterday. He worked wholeheartedly and was very efficient.

"Did you also find out?" Riddle's eyes became meaningful, "The pursuit of more powerful magic 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,

More powerful than others."

"What you said is not wrong." Erwin's reaction was rather dull.

"The magic awakening potion can stimulate the potential of blood, which is very important for young wizards in their growing period. However, the potions provided by this school can only meet the most basic requirements. If you are just a mediocre person, then a bottle of magic power every six months

Awakening is enough, but as long as you have a little talent and ambition, you will not be satisfied with this."

Riddle looked directly at Erwin and continued slowly: "By mastering the production 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 purchase additional ones.

, this way you will have a lot of friends, and you can gather some people around you. Friendships maintained by interest relationships are the strongest, aren't they?"

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

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

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

"Well, actually the process of brewing the potion is not difficult." Riddle shrugged, "As I told you a few days ago, the biggest difficulty is actually in the material processing. The more complex the potion,

The requirements for the state of the raw materials are even more stringent. Powder, paste, liquid, concentration, viscosity, and temperature all have different requirements. You can’t make any mistakes.”

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

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

Erwin did not reply. He stretched out his hand, and the black cube formed by the collapse of Flamel's hut began to rotate and expand to a size of one meter in length.

A crack opened, and Erwin took out one bottle after another.

Riddle's expression changed one after another. Those bottles and jars contained raw materials that had been processed - and he had only told Erwin the processing requirements for those raw materials two days ago, and Erwin had only received the materials one day ago.

He confirmed again, yes, everything was handled according to strict requirements, and this kind of workload would take even the most skilled pharmacist at least a week to complete.

"How did you do it?" He couldn't help but ask Erwin, feeling a little out of control for the first time.
