Felix sent Justin away and returned to the office.

He had never thought before that he would meet people like Weasley Twins. They simply used all their enthusiasm to play tricks and funny things. No wonder when he joined the job, Professor McGonagall looked stuffy with a look of frustration when he mentioned the twins.

‘I don’t know what the magic mobile beggar version they are studying is like?’

Felix thought to himself that although there is a trend of rejecting technological objects in the magic world as a whole, they can still be seen faintly.

For example, the Hogwarts Express, the Knights Bus, the Magic Radio... These are things recognized by the Ministry of Magic and can be used legally, but they need to be reasonably regulated.

The Ministry of Magic has a special department - the Department of Prohibition of Abuse of Muggle Items, which is responsible for handling related matters.

The word ‘abuse’ is already very telling.

Most violators have transformed Muggle items into magic, and then flowed back to ordinary people, causing various magical accidents.

For Felix, it is not difficult to transform it on the basis of an existing mobile phone - the easiest way is to add magic texts to it and block Hogwarts' impact on it, just like he did with a small movie projector.

But what's the use of this?

What he was looking forward to was to see more possibilities and more benign developments and changes in the magic world, rather than to convince wizards to have a mobile phone.

It is indeed an indisputable fact that he has expectations for the twins.

These scattered thoughts flashed through his heart one by one and soon fell silent.

Felix waved his wand, locked the doors and windows, and used magic to impose a thief sensing spell - when someone entered the spell range, the spellcaster could get the message.

He took out the crown from the ring, and after being repaired by Lady Lavenclaw, it was no longer a ragged and rusty shape, but a gem-set crown.

The crown is the shape of an eagle, with a sky sapphire embedded on its chest, and the two spread wings are symmetrically decorated with rows of carefully decorated pearls.

Felix put on the crown.

‘Nothing changed…’

After experiencing it quietly for two minutes, Felix made a record on a piece of parchment paper-

No obvious changes when worn;

Then Felix picked up a stack of parchment paper, which was the information he received from Lockhart, but the "secret inheritance" he mentioned was actually the "surprise" left by Ms. Lavenclaw to the students of her college.

Felix forced himself to temporarily forget the existence of the crown and carefully studied the magic above - he had long memorized this information, and even barely mastered the ancient magic above.

This time, he felt a difference.

His thinking became more active, just like countless fine bubbles appeared on the water that was about to boil, and it became easier for him to retrieve existing knowledge.

Digesting new knowledge is actually a process of continuous internalization - connecting things that are originally unfamiliar with your original cognitive system.

This process requires constantly mobilizing existing knowledge and using the known to understand the unknown.

The crown obviously speeds up the process.

When he thought about memory magic, the relevant memories were obviously activated, and were in an extremely active state, as if shouting at him: I can get in touch with it, look at me!

Felix recorded on parchment—

Knowledge of the same type is more easily mobilized when worn;

After thinking about it, he added, "I am greatly influenced by my own knowledge reserves and cannot directly provide knowledge."

In order to verify this conclusion, Felix flipped through his collection and found a book called "A New Theory of the Political Properties of Power", which was also one of Professor Snape's alternative Christmas gifts at that time. The reason I chose it was because the handwriting on it was small and dense, and the content was so boring that it could make people bald.

He looked at more than a dozen pages patiently, and felt his stomach keep surging.

He wrote a line of words on parchment paper—

To completely unfamiliar areas, the help of knowledge blind spots is almost impossible.

Afterwards, he conducted seven or eight tests one after another, and kept recording them on parchment.

It became dark before I knew it.

Felix looked at the entry recorded on the parchment and compared it with the mind hut, thinking speedup, and Bafe's brain wake-up potion.

Among these three, thinking acceleration focuses on improving reaction ability, which is actually a duel magic;

The other two are: the thinking hut speeds up the speed of thinking and gives the illusion of prolonging time. In other words, it is to complete the conclusions you draw from three hours of thinking in reality in one hour;

And it does not connect with reality. After all, people cannot improve their practical ability through ‘thinking’.

As for Bafei's brain-waking potion, it is not that harsh. It can significantly enhance brain power. Since it is a potion used in reality, it has effects in memorizing knowledge and magic exercises. However, it is actually more focused on the memory of knowledge. Many young wizards look forward to using it to cram the moment before the exam.

"Sure enough, the crown is more useful." The advantage of being able to activate specific knowledge areas and accelerate the absorption of new knowledge of the same type is enough to attract people.

Moreover, from the beginning of the research to now, almost six or seven hours have passed, and Felix has no other sequelae except a little hungry.

To be cautious, Felix took out the "psychometric table" that had not been used for a long time, revised it and prepared to record it for a month.

He was not worried about Ms. Ravenclaw's harm, but was afraid of any unknown impact.

Felix took off his crown and looked at it quietly: "There is no obvious disadvantage except for the feminine look."

"Actually, looking carefully, it's just a little slender and clever, not necessarily exclusive to women. Ms. Ravenclaw is very majestic..."

After ten o'clock in the evening, Felix was ready to rest, but a copper Nat in his pocket suddenly became hot.

"I finally waited."

Felix gripped Hot Nat—which matched the one he gave to Dobby, and he responded by injecting magic into the coin.

Then he waited quietly, and after almost a minute—

A house elf wearing an old pillowcase suddenly appeared in the office. The office immediately made a "whimpering" whistle, and Felix casually snatched the sound.

This is the role of the defensive spell he arranged casually before studying the crown.

The elf Dobi was a little surprised, but he didn't ask much, and greeted respectfully: "Dobi said hello to Mr. Haipp, it's so happy to see you again."
