Harry Potter: Reunion with the Enemy

Hogwarts. Restricted section of the library.

Hermione was reading "Analysis of Goblin Crafting", "Secrets of the Goblin Rebellion" and "The Complete Catalog of Magical Items" attentively, and from time to time she checked the description on the parchment sent by Harry.

"A silver sword...Does a goblin product have magical powers? Can it have a positive or negative impact or side effects on Muggles? Can it even influence people's ideas and thus improve their ability to make money?"

Hermione unfolded a brand new piece of parchment, on which was the content of the reply she was going to write to Harry.

Dear Harry:

Spread the letter good.

According to previous information and the goblin products we have come into contact with before, they may indeed have magic or some unique properties. For example, the Gryffindor Sword was made by goblins, and this sword can absorb substances that can make it stronger. It can destroy Horcruxes and kill basilisks, which proves that it does have powerful magic that can compete with these dark substances. Only a true Gryffindor can take it out of the Sorting Hat. This kind of exquisite magic can indeed exist in goblin products.

In addition, some books in the library also prove that the jewelry made by goblins may also have strong negative magical effects. The "Hope Diamond" is a very famous jewelry in the Muggle world because this diamond weighing 45.52 carats is very beautiful and is currently on display in the National Museum of Natural History of the United States. This diamond is also called a cursed diamond by Muggles because every owner of it has faced disasters without exception.

In fact, the "Secret History of Goblin Making" in the restricted area mentioned that the Hope Blue Diamond was actually made by a goblin, and was circulated through jewelers to King Louis XIV of France, Queen Mary, King George IV of England, Aveline, heiress to the Washington Post, and so on. Although the previous owners were famous and had high status, these Muggles all encountered misfortune without exception.

Therefore, it is very likely that the silver sword you mention in your letter has some of the properties you have speculated.

In addition: Considering the confidentiality of the project, you may not be able to provide more details, but I strongly recommend that you do a thorough magical inspection before touching these items and pay attention to safety.

Hermione signed her name hesitantly. She sensed a hint of danger from Harry's description. If Harry had been studying at Hogwarts, she would have suggested that he give the mysterious silver sword to the professor at the academy for thorough testing. However, Harry was now an Auror tasked with keeping secrets and had experienced so many adventures. He should be able to handle it well.

Hermione tied the letter to the feet of the owl that had been waiting for a long time. Then she sat back at the table and read another pile of books. This time it was about the research topic of Arithmancy.

As an excellent witch, Hermione has always been a good student who studies hard, but when she really started to study magic, she found that it was time to make some changes. Because she found that she had gradually reached the boundaries of previous research, and to expand the boundaries of knowledge further, she had to have her own innovations and ideas.

Standing on the shoulders of giants, one can clearly see the achievements and scope of research of existing wizards, but every step after that is mysterious and unknown, with countless errors and unverified conjectures ahead.

When studying at Hogwarts, the traditional method of learning is to comprehend and practice textbooks and teachers, and achieve perfection through repeated memorization and repetition. Hermione rarely questions textbooks or teachers. In the sixth grade, Harry used the Half-Blood Prince textbook to brew potions with a modified version of the operation method and got a high score, but she still prefers to follow the textbook's instructions to complete the original steps.

Hermione's attitude towards knowledge and teachers is almost religious.

This pursuit of knowledge and study of magic is not motivated by fun and making money like the twin brothers, nor is it infused with desire and ambition like Voldemort, but it also lacks the critical and personalized thinking like Snape.

In the relatively unpopular and difficult branch of magic research, arithmetic divination, the content that can be studied is limited, because the existing magical creatures include centaurs - they are natural fortune tellers who can explore the future from the stars. This is destined to be an ability that wizards cannot obtain.

Among wizards, there are also natural fortune tellers. Although Sybill Trelawney did not inherit the stable prediction bloodline of her relatives, her existing abilities allow her to occasionally make true predictions.

In the eyes of many wizards, it is absurd to use unchanging numbers to predict the ever-changing human thoughts. However, through Hermione's study and some previous research, it can be found that the current research conclusions of arithmetic divination in deriving personal character and general destiny are quite convincing.

After reading all the books on arithmetic divination, Hermione discovered that this subject still had many areas to explore. For example, the profile of specific future events was still not clear enough, and arithmetic divination relied more on numbers related to "people". At present, there was no relevant content for the entire event, the entire country, or larger goals.

But Hermione also found it difficult to take the first step in innovative research. Should she write a formula or spell based on her intuition? Then verify it? Or should she think of a theorem? Then find a bunch of evidence for it?

A few days ago, Hermione met Neville in the classroom who had lost his lesson plan. At that time, Neville once again made a sensation in the wizarding world because of his research on herbal medicine applied by dragons, which was featured in the character section of the Daily Prophet.

Hermione asked Neville, somewhat puzzled, how he came up with some "new" research results.

Neville's face, which had turned red because he couldn't find anything, became serious after hearing the question.

“Because nothing that exists can solve certain problems.”

"Before this herbal medicine was put into practice, I was invited to Romania, where Ron's brother Charlie worked, to watch dragons. I found that Charlie and his friends had more or less been burned by dragon flames because they had to come into close contact with dragons. So I thought of this herb that would overreact on wizards before, and maybe it would be just right for large creatures like dragons. I didn't expect that just one attempt would result in a series of successful results."

Neville scratched his head in embarrassment. "I just want to find some new ways to reduce the danger and pain they have to face. All research results have two sides. It is said that the herbal medicine I proposed is also used by dark wizards to domesticate dragons in large quantities for profit. Dragon scales are a very dangerous material."

Hermione patted Neville's shoulder hastily, "This isn't your fault."

Neville forced a smile on his round face. "Arithmetic divination is also a difficult branch of science. Dumbledore once said that predicting the future is difficult because the cause and effect of people's behavior is complex and changeable. More importantly, prediction is also a part of the result."

Finally, Hermione helped Neville find the lesson plan from the crack of the table.

Before Neville hurried off to class, he suddenly turned around and added, "You will definitely shine with your new research. You are the best Gryffindor of our class."

Hermione's thoughts returned to the parchment spread out in front of her. She pondered for a long time, and finally wrote "Guess 1..." on a new page.
