Half-Blood Prince

In his view, Magic Power Reserve was related to a Wizard's physiological growth. That is, it could be increased with age. Training the body and consuming ingredients from magical creatures could also achieve this effect. After eating Hagrid's Dragon Liver before, he felt his Magic Power had become much more abundant. Thinking of this, Anduin almost forgot that Hagrid was another source of resources he could exploit. He thought he might as well visit him when he had free time, perhaps he could even get some Dragon Meat to eat.

Magic Strength, on the other hand, was more influenced by willpower and emotions. This was also recorded in the Spell textbooks. Often, an angry person's offensive Spells would be greatly enhanced in power. Many dark-minded Wizards found it twice as effective to master dark magic. The description of willpower was rather vague, but for some Wizards with strong willpower, their Spells were often stable and powerful when casting. Anduin was precisely such a person with extremely firm willpower.

Magic Sensitivity was a concept Anduin learned from Professor Flitwick. Through practicing martial arts, meditating, and his previous training with the Levitation Charm involving weight and delayed casting, Anduin found that his control over Magic Power became increasingly effortless. He didn't understand what this represented before, but now he did: it was a symbol of enhanced Magic Sensitivity. Hardening his muscles and bones could make the connection between Magic Power and his body tighter. Meditation and sitting in contemplation could empty his mind, enhancing his perception. Weight training and delayed casting could keep his Magic Power in a state of output and activity, all of which were beneficial for a Wizard to perceive Magic Power.

Anduin planned to continue this training. Slytherin's Dormitory was quite spacious, after all, the underground area was vast enough for him to practice. As for a practice ground for Spells, Anduin decided to get a basic grasp of most Spells before looking for one.

With his future plans sorted, Anduin plunged into a mountain of books.

After what seemed like a peaceful week at Hogwarts, the conflict between Slytherin and Gryffindor slowly began to unfold.

"The Centuries of Charms journal is a monthly publication, released once a month. It's collected in the Hogwarts Library, but the quantity is limited, so you'll have to see if you can get a copy. Also, there's a delay of about half a year. The current month's magazine won't be in the Library; if you want to read this month's issue, you'll have to wait half a year. This is to protect the publisher's sales, as no one wants their directly published work to be pirated for free. You can try borrowing some back issues first; the content is quite good. I'm also responsible for some editing and reviewing work for this magazine."

Half a month later, after Charms Class, Professor Flitwick explained in detail to Anduin, who had come to inquire about the journal.

"I see. Thank you, Professor. But what should I do if I want to subscribe to the Centuries of Charms magazine directly?" Anduin didn't want to be half a year behind others. Moreover, the library probably only had one copy per month, and he might not even be able to borrow it, which would be very frustrating.

"If you're thinking of subscribing, that's perfectly fine. A year's subscription to Centuries of Charms is 24 Galleons. The price isn't low. If you want to subscribe, just give me the money, and I can help you send the subscription letter to the publisher." Professor Flitwick saw Anduin's intention to subscribe and considered it a sign of strong thirst for knowledge, so he happily explained it to Anduin.

Is this for real? The Daily Prophet I subscribed to only costs 5 Knuts per issue, and that's daily. The cost of a Spell journal is a bit beyond Anduin's expectations. 24 Galleons a year means 2 Galleons per issue. Many magical textbooks are around this price. This is a bit expensive for Anduin, but then he thought about it again and felt unwilling to give up, so he made up his mind.

"Professor, please subscribe me for one year. Also, if possible, I'd like to buy copies of the past six months' magazines as well." Once Anduin made up his mind, he no longer hesitated and directly paid Professor Flitwick.

After paying Professor Flitwick 36 Galleons, Anduin instantly felt much emptier.

This won't do. I need to find a way to make some money. My potion-making plan needs to be prepared in advance. Anduin decided after a moment's thought.

After bidding farewell to Professor Flitwick, Anduin didn't immediately return to the Great Hall for dinner. He planned to visit the Potions Classroom. With a period of intensive study, he should be able to quickly master some potion recipes.

The act of scavenging old textbooks wasn't inherently good or bad. Professor Flitwick had approved of Anduin studying old textbooks from the Charms classroom. However, Anduin hadn't communicated with the professors of Transfiguration and Defense Against the Dark Arts about searching for old textbooks in their classrooms. He already felt a bit guilty, and Professor Slughorn was the Head of Slytherin House, so Anduin had always been hesitant to 'do this' in his own Head of House's classroom.

But since he had made up his mind, he couldn't hesitate. He would act immediately. With that thought, Anduin 'tiptoed' towards the advanced Potions Classroom.

After some time, Anduin slipped into the 6th-year Potions Classroom. He had already visited the Potions classrooms for years 2-5. Besides obtaining some potion textbooks, he had actually found a recipe for Veritaserum in a locker in the 4th-year classroom. The recipe was tucked between two tattered textbooks, looking like it hadn't been touched for years, covered in dust. Anduin unceremoniously took it into his possession.

Anduin skillfully used an Unlock Charm to open the locker door. Inside, there were several old 6th-year textbooks. Hogwarts' textbooks hadn't changed for many years, so all the textbooks Anduin saw were Advanced Potion-Making written by Libatius Borage.

Seeing this, Anduin didn't waste any time and began flipping through them one by one. When he opened an old textbook with a slightly worn cover, he found it densely filled with notes. He had only seen textbooks with such a high density of notes in Lily's 5th-year Charms book. Seeing this, Anduin couldn't help but feel delighted. It seemed he had found something valuable! Every time he scavenged old textbooks, it was like a lottery; the same textbook could have completely different value.

After a rough flip-through, Anduin was certain this textbook was extraordinary. Anduin returned to the first page, wanting to see whose book it was so he could express his gratitude later.

"Half-Blood Prince?" Anduin thought the owner of this book was quite arrogant, calling himself a prince. This reminded Anduin of how, when QQ first came out in his previous life, many people's online names were like "So-and-so Prince" or "So-and-so Boy."

After musing about the past in his mind, he quickly put away the potion textbook of this show-off prince and left the Potions Classroom.
