Dudley has been very busy lately, and even the rest of the discipline team can't see him except for their daily morning exercises.

Every day, I studied until late at night, and then dragged my tired body back to the dormitory.

Recently, when observing the resurrection stone ring, I was occasionally inspired, and I plan to add it to the design of the magic dress, which has now reached a critical moment in the experiment.

There is a room in Hogwarts Castle, where the space is wider than the playground outside, and the whole room is applied a very powerful Traceless Stretching Charm, resulting in a 'building-within-a-room phenomenon' inside the room, that is, the space in the room is the size of a building, like an infinite nesting doll, which is very magical.

It took a lot of effort for Dudley to find it with the help of the power of the Data Magic Eye.

The Room of Requirement is one of the most mysterious rooms in Hogwarts, but it is not the only magical room, the Room of Requirement is characterized by the fact that it can constantly change according to the needs of the person who opens the door, to the point where all wishes come true, the room chosen by Dudley is characterized by being large and highly secretive, before Dudley leaves Hogwarts, no second person can open it, and Dudley is not very clear about the specific principle.

In short, this room was requisitioned by Dudley as a laboratory.

The magic of Hogwarts is that even as a Headmaster, you don't know how many special rooms there are, how many special passages there are.

To master the magic of Hogwarts as a whole, the Headmaster alone is not enough, because the so-called Headmaster does not have much authority over the castle.

Hogwarts was founded by the Big Four in 990 AD, and during the Big Four there was no concept of headmasters, only four separate heads of schools (the Big Four), and Hogwarts was made up of four different factions at that time, and this situation lasted until after 1100 AD, that is, in the 11th century, when the first headmaster appeared.

It was also at that time that the principal's office was established

Until then, the Headmaster's Office was just one of many magical rooms at Hogwarts.

In order to fully master Hogwarts, one must obtain the inheritance rights from each of the Big Four, and no one knows where the four put the inheritance. According to Dudley's current information, the Headmaster's authority began with a quarter of Hufflepuff, after all, she was the mildest of the Big Four and the easiest to get access.

It is said that 40% of this quarter of the authority is given to the principal, and the other 60% is divided into 12 shares, which is the prototype of the current 12 school managers, not the 12 school directors who are only responsible for paying money and do not have the authority as Dudley thought at the beginning.

So the Headmaster of Hogwarts actually only has one-tenth of the full authority over the castle, and each of the twelve Trustees has 1.25% of the authority (Dudley now holds 1.25% of the authority), but the twelve Trustees are able to remove the Headmaster because they have more than one-tenth of the combined authority.

In this exclusive 'laboratory', a very complex array of alchemy was drawn on the floor near Dudley, one on top of the other, and piles of materials were scattered on the ground, and the large cylinders next to it were filled with silver liquid, glowing in the moonlight.

"Your alchemy skills are perfect."

Grindelwald's voice rang out in the empty room.

"Actually, you should communicate with that old man Nick Lemay, although his magic level is average, but he has unique insights in alchemy, even I am slightly inferior to him."

During the day, Grindelwald was in charge of teaching the fifth graders, and at night he would talk to Dudley on the phone from time to time, but fortunately, Defence Against the Dark Arts classes were not held every day, otherwise Grindelwald would have been a little overwhelmed.

"Professor, Mr. Nick Lemay has been dead for several years."

Dudley put down his tools and turned his head to alert a gold-rimmed black phone bug, holding a pair of uniquely shaped glasses with a faint blue glow, which at first glance were alchemical items used to relieve eye fatigue.

Of course, it was developed by Dudley.

"Oh, I forgot, you know that people have a memory that deteriorates as they get older, even wizards."

Grindelwald's voice rang out again, and he had been in a much happier mood since the last phone call with Dumbledore that night.

“.”

I believe that you are a ghost, others may forget. But you definitely won't

Oops, the old man is very bad.

Nowadays, Dudley can really only consult Grindelwald about alchemy, and other wizards are not as good as him in this regard, and the alchemy master is a rarer existence than the potions master, and it is a hidden subject among many subjects at Hogwarts.

Alchemy is too talented, not everyone can play it, and among the people Dudley knew, except for Grindelwald, only Dumbledore knew alchemy (discovering the twelve uses of dragon blood with Nick LeMay), but his level was a little worse than Grindelwald.

This dark wizard who almost turned the world upside down is really good, and he knows a little bit about almost all subjects, and he covers a very wide range of subjects

According to him, it doesn't take much effort to sacrifice a little spare time for study for the sake of 'that greater good'.

If other wizards heard that they could tilt their noses like Armstrong whirlwinds spraying Armstrong cannons, the heights that others had spent their entire lives pursuing, he had only used a little business time to learn.

Sure enough, the gap between people is bigger than the gap between people and pigs.

The refining array appeared in front of him, layer after layer, one after another ancient magic texts were placed on the ground by Dudley, and the wand in his hand kept waving up and down, sometimes fast and sometimes slow, like an excellent conductor, with a burst of strong light rising alchemy completed

A puddle of mushy silvery-white viscous liquid appeared in front of him.

Dudley moved his fingers slightly, and the puddle of silvery-white liquid began to squirm from the ground to the rhythm of his fingers.

The frequency is getting louder and faster, and the peristalsis is getting faster and faster until it is able to maneuver normally.

Then the silvery-white liquid began to change shapes, sometimes lengthening, sometimes shortening, sometimes rounding, sometimes hardening, forming a variety of different shapes.

Even Dudley's finger was raised, and the pool of silver liquid formed the shape of an umbrella, and the finger rotated again, forming a sharp sword.

Changeable, the heart moves at will.

However, when Dudley's finger was lowered, the pool of silver liquid scattered from the air as if it had lost its soul, forming small droplets of water on the ground.

Looking at the silvery-white liquid scattered all over the place, Dudley shook his head slightly.

Undoubtedly, it failed again.
