After returning home, Felix went to the workbench and began to transform the tooth:

first, he drilled a hole at the bottom of the tooth;

second, he smoothed the hole;

third, he placed it under a microscope and used a chisel purchased from a microcarver to carve neat ancient magic words, which were nested to form a circuit.

This is a delicate job. Constructing a magic word circuit in an extremely small space, it can be said that very few people in the entire magic world can do this. And Felix reduced the difficulty of the entire magic process by two-thirds with professional chisel tools and the latest generation of microscopes purchased at a high price.

This is one of the results of his theory - the combination of Muggle wisdom and magic. The

so-called Muggle wisdom does not only refer to some of their strange ideas, but also the tools they use to study and transform the world, which are also very fascinating.

In the wizarding world, few people can do this.

Pure-blood wizards, some of whom hate Muggles, and some of whom are not repulsive at best;

mixed-blood wizards or wizards from Muggle families, may be more familiar with the Muggle world, but at the critical time point of 11 to 18 years old, their energy is mainly on magic. After adulthood, the thinking mode has long been fixed, and it is impossible to combine the advantages of the two in depth.

...

It was not until the afternoon of the next day that Felix completed the construction of twelve sets of magic runes. Each circuit had three or five ancient magic runes at the shortest and more than ten at the longest. As the last ancient magic rune was completed, he carefully connected the twelve sets of circuits to form a whole.

The magic circuits were lit up one by one, and the brilliance of magic bloomed in the narrow space!

As the last circuit was lit up, the entire twelve sets of circuits were finally completely closed, forming an endless whole, turning into a bright and unified mysterious pattern.

The small hole in the tooth began to expand without a trace, and soon became the size of a suitcase. This expansion did not end. Felix waited quietly, recalling the results of this day and night, with satisfaction on his lips.

Finally, the space inside the tooth expanded to the size of half a room. Then, the concealment circuit began to work, and the surging magic fluctuations were quickly reduced until they were undetectable; the stability circuit began to stabilize the entire magic structure, and the solid circuit made the tooth, the carrier, very solid and difficult to wear...

The most important thing is the start circuit, which will only be opened according to the conditions he set.

Felix smiled with satisfaction. The third cave was completed!

He took out the suitcase and transferred the things he had prepared long ago into the tooth cavity. Felix positioned it as a "portable spare material storage room". There were not only seven or eight magic wands (obtained from the hands of the dark wizard), but also various magic potions, flying brooms, tents and other items.

After completing all this, Felix stuffed the tooth into his mouth and fixed it with magic.

He smacked his lips, nothing unusual, and licked the wisdom tooth deep in his mouth with his tongue. Hmm, it was not much different from a real tooth. Dr. Granger's skills were really good!

Felix sat quietly at the desk, his eyes calm and long.

All his belongings, most of the commonly used and unimportant ones, were in his suitcase;

and the important items, as his backup supplies, were divided into three parts, which was the three burrows of a cunning rabbit.

The first burrow: the gem ring on his left hand, which stored some of his precious materials, potions, books, and some research results, and was engraved with hidden magic runes;

the advantage was that it could be carried with him, which was convenient for daily use;

but the disadvantage was that it would inevitably be noticed if it was used too many times, and it would be difficult to escape the sight of advanced wizards;

Felix positioned it as a daily necessity, and something that was placed in the open to attract firepower.

The second burrow, the magic rune circuit on the right wrist, only stored a spare wand;

the biggest advantage was that it was extremely hidden and almost impossible to detect by conventional means;

Felix positioned it as a weapon for desperate counterattacks!

The third cave, "Felix's Wisdom Tooth", stores a large amount of conventional and strategic materials;

its advantage is also extremely hidden;

Felix's positioning of him is: when he encounters a major crisis and has to hide and flee, he can be provided with sufficient supplies.

"This is almost safe."

Felix believes that people with such a sense of crisis as him are absolutely rare in the wizarding world. Perhaps some experienced Aurors have this idea, but their methods are definitely not as good as his.

Especially since he is proficient in brain occlusion, conventional torture can't make him reveal secrets at all!

Of course, this is the worst scenario, and Felix doesn't think he will fall into this situation. However, things are unpredictable, and we must always be more prepared.

In the next few years, the British magic world will be shrouded in a shadow called "Voldemort".

Felix never dared to underestimate him. Perhaps this second-generation Dark Lord has a problem with his IQ, but he is definitely a magic genius, and he has been studying magic for much longer than himself, not to mention that the subject he is studying is the unconventional and evil "killing and death".

Less than a week before the start of the new semester, Felix was ready to relax. He was so exhausted during this period!

Watch a movie, listen to a concert, and enjoy delicious food. After all, he still had 100,000 pounds in his account! He would be in the wizarding world for most of the future, and this money could not be converted into Galleons. It would be a waste to keep it!

Felix spent a lot of pounds to buy a series of Muggle supplies as a pastime after teaching.

In particular, he spent 8,000 pounds to buy a small projection device, the kind used in movie theaters, and it was also equipped with copies of classic movies on the market. As for the fact that Muggle items cannot be used in Hogwarts?

Is this a problem for him?

Similarly, music is also indispensable. Felix considers himself a standard Slytherin, and he enjoys it as much as possible.

As the school is approaching, Felix tidied his room and put all the magic items into a suitcase. If a thief came to the door and took away one or two magic items, it would be a big trouble.

"Is there anything else I need to prepare?"

Felix thought for a long time, and suddenly patted his wise little head, "Oh, books!"

He remembered the hint from the principal during the interview, and first bought several pairs of wool socks in different colors, and then began to go on a shopping spree in major bookstores.

There are some for him to read, and some Christmas gifts for professors. Whether they are useful or not, they are ready.

Felix is ​​going to give his former dean a copy of "Common Experiment Operation Guide for Middle School Students", well, the kind with many illustrations.

I hope he will like it.

I believe he will like it, after all, I am his best student!

Felix is ​​looking forward to his job.
