The Magical Principles of Natural Philosophy at Hogwarts

Riddle could roughly guess that Erwin had received the inheritance of a certain high-level wizard. He was not particularly surprised when he witnessed Erwin many times having a cubic container that contained both space folding and seamless expansion effects.

Of course, the main reason why he can maintain this state of mind is that he still doesn't know that this cube can continue to expand and eventually become a fully functional alchemy building group.

It is impossible to buy these processed materials directly, because each potion has different requirements for the state of its raw materials. For example, this semi-carbonized laurel leaf powder is only used when making magic awakening potions.

, Under normal circumstances, no wizard would make the intact bay leaves in his hands like this and then sell them.

Could it be that someone was helping him? Some senior students, or even Hogwarts staff, helped him prepare these medicinal materials?

But Riddle had directly observed Erwin's daily life in the past few days, and he clearly remembered that Erwin had not interacted with anyone who could handle the raw materials for him.

Then there is only one possibility left, that he has a very advanced magic crucible or some other magic potion tool.

Riddle admitted that he was jealous. This boy was not only talented, but also had such good luck. Dumbledore probably knew about it, and he might even have directly contributed to it. Otherwise, why would a Muggle-born boy be so lucky?

Opportunity?

No wonder this kid had so much trust in the old guy. It took him a lot of effort to barely stabilize him and hand him over directly without him.

This kid now regards him as the target of wanton oppression. It is impossible to say that Riddle is not angry at all, but he holds back and does not comment on his situation.

He has no ability to counterattack the opponent now. Erwin's shrewdness and caution far exceed that of a normal adult wizard, leaving him no chance. But he is not impatient. Although he only has sixteen years of memory, he has learned from that numbness.

Since entering the Gua Orphanage, he has long been accustomed to this kind of tolerant life.

As long as enough interests are involved, the relationship between the two parties will continue to change. By then it is hard to say who will control who...

Of course, Erwin has a very clear understanding that the essence of cooperation with Riddle is to seek skin from a tiger, but in everything he does, he must consider risks and benefits, and the benefits of currently dealing with Riddle are obviously much higher than the risks.

Nothing is perfect in this world.

When he first came into contact with potions, Erwin thought about the possibility of assembly line production, and Nick Flamel, a master alchemist, obviously had similar ideas earlier than him. The set of potions in Flamel's cabin

The auxiliary device can complete the processing of almost any medicinal materials and can greatly save time.

If there are dozens of such devices, it would be enough to be called industrialization.

But unfortunately, it is only to this extent. The entire device is very complicated and almost difficult to copy. Erwin expects that he will have to study for at least several years to imitate it. Moreover, the production line built by relying on the magic text device still cannot replace the wizard.

Final making of the potion.

Because this process requires the wizard to maintain perception at all times and accurately control the reactions between various substances with magic power.

In the final analysis, wizards themselves are the most fundamental productive force.

In this underground secret room, the passage of time seemed to be difficult to detect. Erwin missed lunch without any accident. By the evening, his result was a bottle of somewhat turbid liquid.

"Although the purity is a little low, it can indeed be regarded as a magic awakening potion. After a busy day, I finally have a finished product, which is at least worthy of the materials you wasted."

Riddle's words sounded like words of comfort, but they all had a sense of ridicule and gloating.

This is normal. If it were the first time Riddle came into contact with such a high-level potion as Magic Awakening, he would only be able to prepare such a defective product on the first day. After all, no matter how talented he is, it will only improve the efficiency of practice, and it is impossible to directly

Skip the trial and error process.

If Erwin could prepare the perfect magic awakening potion after only a few attempts, Del's mentality might be unbalanced again.

The worst thing for a genius with a small mind is to meet someone more talented than him.

And Riddle is obviously not a broad-minded person.

Erwin rubbed his sore wrist. He did not have any negative emotions because of Riddle's words. The more advanced the potion was, the more difficult it was to make it. The successful production of the finished product was somewhat unexpected. This was different from what he had done before.

The mid-level and low-level potions produced have a completely different feel.

Yes, defective products can be considered finished products, and the magic awakening potion he made is effective.

After all, this was his first time coming into contact with such complicated potion preparation, and there were many techniques and precautions that he had never heard of before.

If you practice a few more times, the situation will get much better. After all, he is only thirteen years old, so he has plenty of time.

No need to be too impatient.

It was already very late, and he might not even be able to make it in time for dinner if he stayed any longer. Erwin motioned for Riddle to retract his diary, then left the secret room with the diary and stepped up the stairs.

The witch statue blocking the entrance to the secret passage had just moved away, and Erwin happened to see two boys running towards them. They were stumbling, panicking, and wearing baggy and ill-fitting clothes.

Who is it if it's not Harry and Ron?

Erwin reacted quickly and immediately waved to them and let them enter the secret passage.

The two boys held their knees with their hands and were out of breath.

"What's going on with you?" Erwin asked, leaning against the wall with his arms folded.

"The secret was almost exposed. If I were to run away half a minute later, I would have bumped into Snape!" Ron's expression was very exaggerated.

"We drank Polyjuice Potion and disguised ourselves as Crabbe and Goyle." Harry added with some difficulty: "The good news is that Malfoy didn't notice it, and the bad news is..."

"We didn't get any useful information." Ron was a little frustrated, but then he became energetic, "But it feels good, doesn't it? Look at Malfoy's arrogant and stupid look."

"Brother Yan doesn't know the key information?" Erwin was not surprised.

"He said his father didn't tell him the details at all." Harry sighed.

They worked hard to brew the Polyjuice Potion and made plans, but in the end they achieved little results.

Grain loss

"But it's certain that Dobby is the elf of the Malfoy family." Harry rolled his eyes, "I mentioned it to him on purpose, but he didn't deny it."

Erwin nodded slightly, and Harry was a little more cautious now.

"It was indeed Malfoy who instructed the elf to cause trouble in the football game!" Ron's anger immediately rose.

Harry smiled bitterly.

"In other words, Dobby still comes to see Brother Yan from time to time?" Erwin asked.

"Yes, Malfoy said that his elf just brought him a lot of things from home yesterday."

Erwin nodded slightly. It seems that house elves can sometimes act as owls, and can play a greater role than owls. Apparition is quite convenient and fast.

It is really an excellent and worry-free servant race.

According to Dumbledore, Erwin no longer needs to worry about this matter, but he is still quite interested in Dobby himself and the Malfoy family.

So he had an idea...but it wasn't the time to execute it yet.

"Why are there just you two? Where's Hermione? Didn't you say you wanted to act together? Has she been caught?" Erwin suddenly realized that someone was missing.

Hermione had said in the morning that she would drink the Polyjuice Potion with Harry and the others.

The two boys looked at each other and said, "Hermione...should still be in the bathroom on the second floor."

"Why are you there?" Erwin frowned.

"We drank the Polyjuice Potion together in the abandoned bathroom." Ron explained: "Harry and I quickly completed the transformation, but something seemed to have gone wrong with Hermione. She locked herself in the compartment.

inside, and then urged us to go directly to Malfoy."

"We have to find her," Harry said.

The three of them walked out of the secret passage together and hurried upstairs. As soon as they entered the bathroom door, they heard bursts of sharp and mean laughter.

"It's the ghost Myrtle who lives here. She's a little crazy." Ron explained.

"Warm kitten, soft kitten..." Myrtle began to sing a song that was confusing.

"Hermione is crying," Harry whispered, hearing sobs coming from the cubicle.

"Shut up!" Ron yelled angrily at Myrtle who suddenly floated over, and received a sharper laugh in response.

"Hermione, are you okay?" Harry knocked on the cubicle door worriedly.

"I...it's okay." After a few seconds, the girl replied quietly.

"Are you really okay?" Erwin spoke, his tone was calm and reassuring.

"Always shutting yourself in is not the answer."

The door to the compartment opened, and Hermione covered her face with tears in the corners of her eyes.

From the gaps between her fingers, you can see the black hair on her face. Her eyes have turned yellowish brown, and two cat ears have grown out of her brown hair.

Harry and Ron gasped.

"I thought it was Millicent's hair, but it was actually cat hair." Hermione felt aggrieved.

"It shouldn't matter, it will change back after a while..." Ron tried to comfort him.

Harry shook his head, it seemed that the actual situation could not be changed back.

"You must go to the infirmary," he said. "Madam Pomfrey should have a solution..."

"Then how should I explain it?" Hermione became a little emotional. "How should I tell Madam Pomfrey that I have made myself look like this?"

Harry was speechless.

To tell the truth, everything will be exposed, and they will be investigated starting from the crime of stealing school medicine.

Erwin also frowned slightly, "How should we deal with this situation?"

He was asking about Riddle.

"Polyjuice potion accident? It's pretty typical. It's not difficult to deal with..."

Just as Riddle was about to speak, Myrtle suddenly looked at Erwin in extreme horror, suddenly let out a shrill scream, and shrank into the toilet.

"Can she sense you?" Erwin realized something was wrong.

Riddle snorted coldly.
