Peter looked confused, but as an adult wizard with a normal IQ, Peter quickly parsed something extraordinary from Ivan's words.

"If you figure it out, drink the medicine, I don't want to listen to your nonsense anymore!" Ivan handed over the brewed improved compound decoction.

Peter took it with a slight tremble, not daring to disobey at all, in his heart Ivan was even more terrifying than the Dark Lord.

Thinking about the time I came in, I vaguely felt that the layout here was a little familiar, and Peter's tears were about to fall...

If he could, he'd rather not know anything himself...

However, as a wall-grass without the slightest discipline, Peter knew that if he wanted to save his life, he had to show his worth, so no matter what Ivan had in his hands, Liso drank it all in one gulp...

Peter's reaction surprised Ivan, and he thought that Peter would be reluctant to test the medicine as before.

Next, Peter slowly breathed a sigh of relief after knowing that the little wizard in front of him was only using himself to experiment with potion improvements, and there was no danger to his life, and even diligently worked for Ivan.

Ivan was a little embarrassed to experiment on Peter.

"Master, your herbs..."While Ivan was making the potion, Peter took the initiative to prepare all kinds of materials, handed them over, and said flatteringly.

Ivan was a little surprised by Peter's title, more awkward, he turned his head to look at Peter and said playfully. "Isn't your master the Dark Lord?"

He must want to test my heart! Peter immediately realized this, and immediately burst into tears to denounce the brutality and evil of the Dark Lord, and said that he had already changed his past and drawn a clear line with the Dark Lord!

In turn, Peter began to tout Ivan's achievements over the past few years...

He felt that if he licked fast enough, he would not be abandoned!

But the more Peter talked about it, the more frightened he became, and then he realized that the little wizard in front of him in the third grade had unknowingly done something that many adult wizards couldn't do!

There was also a little more sincerity in the flattering words, and Peter couldn't help but feel that a young wizard like Ivan, who was so gifted, cruel and wild, might really be a good person to turn to.

As for the Dark Lord who has lost his power? He's a fart!

Ivan, of course, did not get lost in Peter's flattery, but had a new understanding of the extent of this guy's shamelessness, and in the face of him, a little wizard in the third grade, being able to put down his body and pretend to be a servant, Peter's endurance was beyond his expectations.

However, because of Peter's active cooperation, the efficiency of the research was much faster than Ivan imagined.

In just one night's work, the data for the improvement potion was confirmed, and it can be said that the improvement work has been completed so far!

Before dawn, Ivan instructed Peter Pettigrew to revert back to Animagus form.

Peter's face couldn't help but show a hint of hesitation,

"Don't worry, my potions research is over, and today is the last!" Ivan said comfortingly.

"Thank you for the grace of the master!" Peter's tears of excitement finally ended.

Peter quickly obeyed the order and shrunk into a mouse, thinking that it must be because of his efforts that Ivan saw him, so he was merciful and forgave himself.

Maybe it won't be long before he can gain Ivan's trust and follow the rising star of the wizarding world, instead of hiding here as a pet of a little ghost.

Just as Peter was in a delusion, a voice suddenly remembered...

"Forget it!"

Peter's frightened expression appeared on his face, and he lost consciousness in the next second.

Ivan put down his wand, picked up the rat on the ground, and left the Room of Requirement.

Ivan, who knew Peter very well, was certainly not prepared to accept this new servant.

No matter how diligent Peter is, he can't wash away the stain of his betrayal of his best friend, and Ivan can't believe it!

Not to mention that Peter is so ugly!

So, I'm sorry... Ugly rejection!

......

The day passed in a flash, and after the last class, Ivan brought the invisibility cloak and potion reagent, and after confirming that it was correct, he walked towards the empty classroom.

Hermione had arrived early, sitting on the sidelines, flipping through a book without even noticing Ivan approaching.

"Decryption of the Dark Arts? When did you become interested in this kind of book? Ivan asked curiously, remembering that Hermione had never read these dark arts books.

"Yikes... Ivan? You're coming—" Hermione, who was looking at the book seriously, was startled, and the little witch snapped the book and covered it, and then said aloud.

Ivan shook his head, not caring about Hermione's act of secretly reading the Dark Magic Book, it was normal for her to be a little curious about those forbidden things at her age, and it would be convenient to deal with them in the future.

Thinking of this, Ivan walked to the side to boil the potion by himself, preparing to repeat the old trick, but when the powerful water of life and death was boiled, Hermione's action of turning the book continued, and it seemed that he didn't feel sleepy.

Ivan patted his head, and suddenly remembered that Hermione had been resting well recently, and the smell of boiling medicine alone was not enough to make the little witch unconscious.

Or secretly add a little life and death water to the energy tonic and let her drink it?

Ivan had all sorts of bad ideas in his head, but none of them seemed to be very safe, and they were easy to spot.

At this moment, Hermione suddenly stopped her hand and walked over with the book, and was about to say something, when she saw the potion that was about to be brewed in the cauldron.

"Ivan, are you boiling the water of life and death?" Hermione glanced at Ivan suspiciously, she remembered that she had smelled this potion before she accidentally fell asleep that day...

Moreover, she was sure that Ivan must have left halfway when she fell asleep that day, otherwise the note would not have been in her hand.

Seeing that Hermione's expression was getting more and more wrong, Ivan had a headache, and sure enough, smart people hated it the most, since it was impossible to hide it completely, Ivan said tentatively.

"Hermione, I happen to have something that I need a time turner, can you lend it to me temporarily?"

Hermione was even more sure that the last time she fell asleep was Ivan's ghost, she gave him a dissatisfied look, but she still untied the time turner hanging around her neck and held it in her hand.

It's just that Hermione didn't hand it over to Ivan immediately, but looked at him seriously and said. "But you said that when you use the time turner, you take me with you wherever you go..."

"Not this time!" Ivan was serious, and even he couldn't guarantee that he was completely safe in Tumbledown Alley, let alone a little witch in the third grade.

Thanks to the book friend Handsangmu for the 100 starting coins.
