Boiling a compound decoction is a very tormenting task - because this potion requires 12 worms that have been boiled for 21 days. In other words, Carl needs to boil a compound decoction from scratch for at least 21 days before it can be boiled.

Fortunately, there is a room for responsiveness. This magical room can even open up many spaces at the same time, so Carl can slowly wait in places where no one discovers it.

If the principal was Dumbledore at this time, Carl would have to go outside the castle to boil medicine. He was not sure that Dumbledore could not find everything in the room for requests. After all, the entire Hogwarts Castle is a small mage tower, and the principal is the owner and the highest authority manager of the mage tower - he knows if Dumbledore would find everything in the room for requests.

Carl has no psychological pressure to teach elemental prayers (as long as you don’t teach ghosts to walk), but it’s different to make a compound decoction.

The 21 days waiting for the potion to be completed were quite long, and during this period, Carl's greatest pleasure was to observe Snape.

From the super doubled points he deducted to Gryffindor the next morning, it can be seen that the potion master immediately discovered the problem of his private collection being stolen.

However, judging from the current situation, he does not seem to take Carl's gift seriously...

I have prepared a gift for you, you treat it as a prank?

Well, too.

The Potions Professor’s office is there, and a large number of herbs are placed in the cabinet. Just a single Ahora hole is needed, and any student can get the potion materials - maybe Professor Snape is used to the stolen potion materials?

This is really terrifying to think about it carefully!

Little Lions in Gryffindor...What did you do?!

………………………………………

In fact, Carl guessed wrongly about Professor Snape's reaction this time.

After Snape discovered that his potion materials were stolen, he found out that the purpose of these materials was - after all, there were not many potions that used African tree snake skin sticks.

After realizing that someone had stolen his ingredients to make a compound decoction, Snape also discovered the notes left by Carl.

After a brief look, Snape discovered that [Blood Soul Swearing Together] is not simple, and this kind of evil magic is indescribable. Although the main contents are about the soul and the contract,... In the eyes of the writer of this note, the factors such as soul and blood are objectively present, and all descriptions are neutral, as if these taboo words are as ordinary as "magic" and "magic wand".

With Snape's eyesight, it is not difficult for him to see the danger of this note. This danger not only comes from the above spell, but more importantly, it also represents a dangerous thinking.

Originally, Snape should have handed it to Dumbledore for such dangerous things as soon as possible. Although Snape has always wanted to become a professor in the Dark Magic Defense Class, the person who has the deepest research in this area is undoubtedly Dumbledore.

But for some reason, after confirming that this was just a note and there was nothing else, Snape chose to put the note away and hid it at the bottom of his desk.

While packing the notes, Snape's rare heartbeat accelerated a lot.

A bold idea appeared in his mind irrepressibly, forcing him to use brain closure surgery with all his might and force himself to calm down.

Yes, Carl's actions were actually very successful. Ten years later, Snape's obsession once again made his calm heart ripples.

As for the calm that Carl is doing, it is just the deepest disguise of a veteran spy.

In this way, after more than twenty days of cooking, Carl finally completed the compound decoction before the last Quidditch in Gryffindor - the compound decoction in Professor McGonagall's hair was filled with amber bubbles. This color was exactly the same as the pupils of the cat after Professor McGonagall's transformation.

Waiting for the potion to cool down slowly, Carl received the amber potion into the bottles prepared in advance, waiting for the weekend.

Of course, before the action, Carl needs to create a little opportunity for herself - Professor McGonagall seems to have been busy with the Order of the Phoenix recently, which is very unfavorable for Carl's transformation operation. Before the action is formal, Carl needs to attract Professor McGonagall's attention and let her temporarily escape from the Order of the Phoenix for a while.

As for how to let her act alone...

Is there any better opportunity than "learning Animagus"?

………………………………………

"What?" Professor McGonagall was shocked when he heard Carl say he wanted to learn Animagus. "Carl, how could you have such crazy thoughts - Animagus is a very dangerous spell, which is not only reflected in transformation."

"I understand, I understand." Carl nodded, looking like I understand everything. "Animagus is not only a complete self-deformation, but the animals he becomes after deformation will also react on the transformer, and even permanently change his personality - these are mentioned in the extended reading of basic deformation."

"Then why do you still want to learn Animagus now?" Professor McGonagall stared at his adopted son seriously. "I know your talent very well. If you are in the fourth or fifth grade now, I will not refuse your request, and will even take the initiative to tutor you to apply for registration. But now, Carl, you are still a child, and you don't even understand the animals. The rash deformation will have an unpredictable impact on you."

"This is carefully considered." Carl looked confident. "The premise of being able to perform Animagus is to use deformation techniques to transform the dead and the living creature for a limited time. Although according to Gamp's law of deformation techniques, it is impossible to transform permanently between the living and the dead, as long as the level of deformation techniques is so high that it can "transcend life to the dead" that it is enough to prove the potential of Animagus."

While speaking, Carl clicked the button on his chest, and the button quickly turned into a scarab that spreads its wings and flew to Carl's palm with its wings, and then turned back to a button again.

"I think being able to make it move spontaneously is already considered to be a 'short-term life to the dead'?"

"It's a good understanding." Professor McGonagall sighed, "Tell me, have you slipped into the forbidden book area?"

"It's not a forbidden book area." Carl's face showed a smile of Plantong, "It's actually the collection of books at home... I remember the name is "Dangerous Transformation". When I read that book, I was five years old. It was really cool to become an animal - but unfortunately you took away all this kind of books afterwards."
