Harry Potter: A Certain Ancient Rune Professor of Hogwarts (TL)

At home, Felix went to his lab and began to modify the teeth.

First, he drilled a hole in the bottom of the tooth to create a small cavity.

Next, the hole got repaired by smoothing it out.

Then he placed it under the microscope and, using a carving knife purchased from a microscopist, carved out a regular pattern of ancient magic runes, nesting together to form a circuit.

This is very delicate work, constructing magic circuits in the tiniest spaces, something that very few people in the entire wizarding world can do. But Felix, with his expert carving tools and the latest generation of overpriced microscopes, has reduced the difficulty of the process by two-thirds.

This is one of the results of his theory of combining muggle wisdom with magic.

Muggle's wisdom is not just about their whims; the tools they use to study the world and transform it with are equally fascinating.

And few in the wizarding world are able to do this.

Pure-blooded wizards aside, some of them hate muggles, others are not repulsive at best.

Mixed blood, or some wizards from muggle families, may be more familiar with the muggle world, but at the critical point of their life between the ages of 11 to 18, their focus is primarily on magic. By the time they reach adulthood, their mindset is already set, and it is impossible to deeply embrace the best of both worlds.

...

It was not until the afternoon of the second day that Felix completed the structure of twelve sets of magic circuits, each of which consisted of three to five ancient magic runes, or some have more than ten. As the last of the ancient magic runes were constructed, he carefully linked the twelve sets of circuits together to form a complete body as a whole.

One by one, the circuits were lit up, and the glow of magic burst across the narrow square space of the tooth.

With the last circuit lit up, the twelve circuits finally form an everlasting unity, a single brilliant and unified mystical pattern.

The tiny hole inside the tooth began to expand without a sign of stopping, soon becoming the size of a suitcase, and the expansion did not end there.

Finally, the inner spaces of the tooth expanded to the size of half a room, and then the concealment circuit came into play, the fluctuations of the magic that surged through the tooth were quickly reduced to insignificance; the stability circuit began to stabilize the entire structure of the magic runes, and the reinforcement circuit made the tooth very strong and unbreakable object ...

The most crucial thing is the activation circuit, which only activated according to the conditions he had set.

Felix smiled with satisfaction, the third cave, complete!

He took out his suitcase and transferred the items he had already prepared into this cave, which Felix described as a 'carry-on spare storage room', containing not only seven to eight wands (obtained from Dark Wizards by defeating them), but also various types of potions, flying brooms, tents, and other materials.

Once this was done, Felix stuffed that teeth into his mouth and fixed it with magic.

He smacked his teeth, but there is nothing unusual about it, and then he ran his tongue over the wisdom tooth deep in his mouth.

Felix sat silently at his desk, his gaze calm and relaxed.

All of his belongings, most of which were commonly used and less important, were in his suitcase.

The more indispensable items, his backup, are divided into three sections, known as the Three Caves of the Rabbit.

The first is his left-hand ring, which contains some of his valuable materials, potions, books, and some of his research, and it is also inscribed with an invisible inscription rune.

The advantage of this ring is that it can be carried around with him, making it easy to use in daily life.

The disadvantage is that when it is used more than once, it is inevitably noticed, and it is difficult to escape the eyes of the senior wizards.

Felix's definition of it is intended to be an everyday object and something to draw attention in plain sight.

The second cave, the magic circuit at the right wrist, stores a mere spare wand.

Its greatest strength is that it is extremely invisible and almost impossible to detect by conventional means.

Felix's definition of this is something that can be used in a desperate counterattack!

The third cave, Felix's Wisdom Tooth, holds a large amount of routine and strategic items.

The advantage of this is also its invisibility.

Felix's idea is to provide him with sufficient supplies when he is in grave danger and has to flee secretly.

" This is pretty much safe."

Felix believed that people as crisis-aware as he is rare in the wizarding world, perhaps some experienced Aurors had such a mind, but their methods certainly wouldn't match his own.

Especially since he himself is an expert in occlumency and standard torture would never get him to reveal his secrets!

Of course, this is the worst-case scenario, and Felix didn't think he would end up in this situation. But things are always unpredictable, and one must be prepared for them.

In the years to come, a shadow is known as ''Voldemort'' will loom over Britain's wizarding community.

Felix never dared to underestimate him. The second Dark Lord may have a questionable IQ, but he is definitely a genius in the field of magic and had been studying it for far longer than he had, not to mention that his research is focused on the deviant and sinister subject of "killing and destruction".

With less than a week left before the start of term, Felix intends to relax, he's been so tired for some time!

Watching films, listening to concerts, and enjoying good food, after all, he has £100,000 in his account! He's going to spend most of his time in the Wizarding World, and he can't convert all of it into galleons, so it's a waste for the time being!

Felix spent a large amount of pounds on a selection of muggle items to keep him entertained while he went to work.

In particular, he spent £8,000 on a compact projection unit, the kind used in cinemas, and accompanying replicas of classic films on the market. As for Hogwarts not being able to use Muggle items?

Is that a problem for him?

Similarly, music is a priority, and Felix considers himself a standard Slytherin, and he will enjoy his life as much as he can.

As school began, Felix organized his room and put all the magical items in his suitcase - it would be a big problem if a thief came to his door and took one or two things.

"What else do I need to prepare?"

Felix thought for a while and then suddenly slapped his wise little brain, "Oh yes, books!"

Remembering the Headmaster's hint at the interview, he bought a few pairs of wool socks in different colours and then started to shop around in all the major bookshops.

He picked up both his favourite books and Christmas gifts for the various professors, whether they were useful or not, but he had them on hand.

Felix was going to give his former head of house a copy of 'A Guide to Common Experiments for Middle School Students', well, one with lots of illustrations.

I hope he'll like it.

I'm sure he'll like it, after all, I am his best student!

Felix is looking forward to his new job.
