The reason why Dumbledore was willing to give the Philosopher's Stone to Regulus Black was also in mind.

That has to start from the characteristics of the Philosopher's Stone, to put it simply, after Nicol Lemay created the Philosopher's Stone, as the master of the Philosopher's Stone, he was also shackled by the power of the Philosopher's Stone, he could only feel joy, happiness and other positive emotions, although he knew that he should feel pain and sadness at some times, but he couldn't really feel it, and at the same time, he could only do things that would bring joy to others, or generally non-impactful behaviors, and could not do bad things, or even bad thoughts.

And the advantage of paying these costs is that he can use the Philosopher's Stone to use the joy of all those whose fate he has reversed, including the poor whom he has relieved, the sick he has treated, the students he teaches, and the people who have been helped by his alchemical inventions.

Perhaps, the Philosopher's Stone fell into Voldemort's hands, and such a shackle may be able to be removed, even Dumbledore himself can eliminate this, but for Regulus Black, although Dumbledore can't see through him, he thinks that he shouldn't have such an ability, and Nicol Lemay is a creator, so he naturally has this shackle that cannot be freed.

To put it simply, it is better to be happy alone than to be happy in everyone, Nicol Lemay can bring joy to the people around him, so Dumbledore also hopes that Regulus Black can also be like this, and be turned into a happy good person by the Philosopher's Stone.

Regulus Black put the Philosopher's Stone in his system space, and saw that this was the kind of attribute, if he didn't want to be affected by the shackles of the Philosopher's Stone, he had to adjust the attribute, or refine it into another thing, and edit the new attribute from the new.

After Regulus Black swept the entire clearance process, what he directly refined was Professor Flitwick's Flying Key, and at most he used Trevor to devour the calendar fire set by Snape, which was still a half-finished product.

Regulus immediately thought of combining the Philosopher's Stone with Trevor to refine an immortal toad.

"Come on! Trevor, obediently swallow the Philosopher's Stone. ”

Although the Philosopher's Stone and Trevor were both in the system space, Regulus Black still muttered to himself with some excitement.

Trevor swallowed the Philosopher's Stone, and under the influence of Regulus Black's magic, it grew in size, and by the time Regulus Black released it, Trevor was already the size of a round table with a diameter of 2 meters.

Trevor has a black lotus pattern on the top of his head at this time, and behind it is a red gem arranged by seven stars, covered with black low-temperature holy fire, and his hind legs have been merged into one, Regulus Black casually gave it a copper nut to swallow, and after a while, a pustule behind it squeezed out a gold coin, although the pattern is still copper, but the material has completely turned into gold, even the magic exerted by the goblins on the currency cannot resist Trevor's refining.

After experimenting with refining metals, it's time to experiment with swallowing water and spitting beads, and many of the potions that the students had to mix at will have been scrapped, but Regulus Black has reservations, so there is no need to wait for a while.

Vasks of scrap potions were poured down, and Trevor was doubled in size.

However, after a while, the body returned to its original shape, and then a three-legged golden toad's egg was born from under its abdomen.

The egg, under the scrutiny of magic, was alive, but Regulus Black knew that it would never hatch.

However, this is a year's lifespan, and I believe that it can be sold for a good price on the black market in Diagonal Alley.

The House Cup was eventually given to Gryffindor, and Dumbledore made Slytherin lose the victory by unreasonably giving Harry Potter, Ron, and the brave Neville, and the extra points for Hermione were not mentioned after Regulus Black discussed with Dumbledore and Professor Flitwick, which disappointed Lori a little.

Since all the students in the school have left at the end of the semester, only staff like Regulus Black will stay in the school, which is also a good experience for Regulus Black, after all, a school without a bear child is a quiet place to study.

Except for the occasional run of his family business, Regulus Black spends most of his time in the library, occasionally going to the Ravenclaw common room to read books.

Today, Regulus Black is looking at the Five Exceptions to Gamp's Basic Transfiguration, which is part of the seventh-grade curriculum.

The 'Five Exceptions to Gamp's Basic Law of Transfiguration' is a major argument made by the famous wizard Sercy Gamp three hundred years ago after a long career of experimentation. It mentions that there are five major exceptions to Transfiguration, which are impossible to achieve.

First, for the purpose of food deformation, it is impossible for a wizard to conjure up a delicacy out of thin air, nor can he turn other things into food, and even if you eat it, it is impossible to absorb nutrients, but it will cause indigestion. However, if you already have some food in place, then you can morph it and make it a little bigger.

The food on the dinner plate in Hogwarts is not conjured, but is cooked by the house-elves and then transported to the container on the table through the 'Shifting Charm'.

The second point is that 'there is no permanent transformation between living and dead things', we can turn a button into a scarab, but it can't move forever, as long as the attached magic dissipates, it will still revert to a button. In addition, even if the beetle is alive, it is still a button, and if you feed it to a bird, it will not fill its stomach and choke to death.

Thirdly, Transfiguration cannot conjure magical items, such as automatic quills, variable temperature cauldrons, etc., even the Golden Galleon, and the currency circulating among wizards is spelled by goblins, it does not oxidize, it is not easy to destroy, and it also has the ability to automatically identify and count.
