The spirit behind the gods

Harry, who had experienced the Quidditch incident and knew the development of things from Ron, finally did not stare at Snape alone this time, and even Quirrell, who seemed to be no threat, also became the object of his suspicion.

Before she knew it, Hermione had entered Hogwarts at the end of the fourth month, and she would also usher in Christmas, a very important holiday in the West.

After 4 months of study, Hermione's learning progress undoubtedly surpassed that of other young wizards of the same generation, especially her spiritual objects of the essence of magic, which were definitely incomparable to other young wizards who memorized magic spells.

Learn, master, understand, apply...

Technology is used in much the same way, and magic can be produced in the same way.

Hermione's family itself was not wealthy, and Hermione naturally didn't have much pocket money, and the only good news was probably that she couldn't find a place to use it at Hogwarts in the first year.

But the lack of money does not mean that Hermione does not need money, most of the hands-on opportunities that Hogwarts can provide come from the free potions in the class, and the experiments that Hermione wants to operate obviously cannot use the school's items, which requires a large amount of gold gallons.

Yu didn't mean to directly lend hundreds of millions of gold gallons to Hermione for free, but let Hermione find a way to make money by herself.

It turns out that after a little person is forced to be anxious, her potential is indeed limitless.

Before Christmas came, Hermione had already come up with the idea of making money.

How do students make money?

The answer is learning and playing!

The former is aimed at good students who are motivated to learn, while the latter is for guys who have no intention of learning.

With Hermione's knowledge, it's not a problem for her to build a Little Overlord learning machine, but the problem is that Hogwarts doesn't have electricity at all!

Hogwarts is insulated from the world of technology, and everything here cannot be directly applied to the technology of the Muggle world.

Unless Hermione can overhaul the entire structure of Hogwarts, the mere problem of electricity will be enough to break everyone down.

Unable to do it directly with technology, Hermione began to work on the ingredients of magic change.

If you play the game directly, you may be directly suspended or even deducted points by the professors at Hogwarts, so that Hermione can only start from the study side.

Photographs in newspapers in the wizarding world can change on their own just like television, but in the end, all of this is like silent films, with only images and no sound, and this technology is only used in very few places such as photos and books.

And Hermione's first invention was the projector magic version.

Images and sounds that have been recorded are then converted into a book by special pressing method in a magic scroll that is only half the size of a palm, and the effects of what happened can be re-manifested by placing them in a special projector.

This may seem like a Muggle VCR, VCD, or DVD, but the important thing is that the image projected by this magic item is a holographic projection, and most importantly, it can be powered by magic without having to worry about power.

The advent of the projector was born entirely to accompany the recording of Hogwarts teaching, and most of the lessons are done once, often after the professor has spoken, he will not talk about it a second time, and even if there are students who want to review the relevant content, they can only review it through other people's notes.

But notes are just notes after all, and even if they are written down by the professor himself, they have certain limitations.

It is possible that the idea when taking notes is very different from what he thought when he was in class, which is undoubtedly a boon for students who want to revisit the content of the class.

As for how to record the footage, Hermione chose two very different ways.

One is to use a third-party magic device to shoot like a camera.

The other does not require additional preparation at all, and directly uses the method of magic spell receptivity to seal the first-person memory into the magic scroll and press it into a disc.

The two methods can be applied to different objects, of course, the effect is also completely different, the former is more professional, the latter is more convenient.

With the success of the first batch of prototypes in the community, a large number of students saw the potential of this prop, and even Hermione registered the trademark rights and invention patents of the magic projector in the wizarding world by writing a letter.

Of course, a simple projector may not be bad, but the market share is far from as large as imagined.

You must know that there are only more than 3,000 wizards in the British wizarding world, how many wizards can there be in the world?

What really gives Hermione the means to make money is that the small magic scroll used to store images has a special technology taught by Yu exclusively, which can achieve the technology of storing a much higher amount of information than the current wizarding world, and the existence of home-based encryption technology, no one in the entire wizarding world can make the same product except Hermione.

From the appearance of magic speculation to the fact that it caused a storm in the wizarding world, the whole process appeared in just one month, if it were not for the unexplained part of the technology of the entire magic projector, which was not suitable for circulation to the Muggle world, I am afraid that Hermione would be able to earn tens of thousands of times more than it is now.

By the time Hermione had put the whole invention on track, she no longer had to worry about making money, and countless gold gallons were deposited into Hermione's account on a monthly basis.

Thanks to Hermione's dominance in all subjects, the serious Professor McGonagall acquiesced in her doing this kind of thing to start making money as a student, and of course, it was also affected by Hermione's donation to Hogwarts.

The first term at Hogwarts ended on December 23rd, and all but those who were not going home for Christmas left Hogwarts by train, and all students did not return to school on the train until January 5, 1992.

January 6, 1992 was the start of the second semester.

It's also thanks to the Hogwarts practice that there is only one final exam a year, and the exam is held in the second semester, otherwise everyone will have to continue to bear the pressure of the New Year before the first semester holidays.

And during a vacation, Harry and Ron's investigation of the Philosopher's Stone that they had overheard finally made epoch-making progress.
