After a day's lessons, and half a day of potions, by the time he returned to his dormitory, Ivan was physically and mentally exhausted.

Harry and Ron were leisurely flying the wizarding flag in the dormitory, and for a thirteen or fourteen-year-old wizard, life was so carefree.

Ivan looked at them with envy, and then looked to the side, eating a multi-flavored bean on Spotted.

Maddara shuddered under Ivan's "evil" gaze, he hadn't forgotten what Ivan had said about the potions he was going to experiment with.

No, this place can't stay any longer.

He's leaving tonight!

......

In the middle of the night, in Gryffindor's bedroom, a gray-black mouse suddenly opened its eyes. After cautiously scanning the surroundings and seeing that everyone was asleep, I breathed a sigh of relief in my heart.

Then Spotted slowly crawled out of Ron's bed on his short legs, but he was so fat that it was hard to get out of bed, and he almost rolled all the way down.

Finally climbed to the door of the dormitory, Peter looked at the high doorknob and was very embarrassed, thinking about whether to change back to his original appearance, the little wizards in the dormitory should be sleeping soundly and not waking up suddenly...

Just taking this step means that he will be away from the current life of eating and waiting for death every day...

Suddenly Peter felt that he was so hard!

In these days, it's not even easy to be a mouse, and there are always people who want to embarrass themselves...

Peter glanced fiercely in the direction of Ivan's bed, before meeting Ivan, he had been disguised as a mouse for more than ten years...

If he hadn't been worried that killing Ivan would cause a lot of trouble at Hogwarts and expose himself, he would have done it a long time ago...

A few thoughts flashed through Peter's mind, but soon Peter noticed that Ivan's bed seemed to be empty, and the quilt looked shriveled....

What about people?

A chill suddenly welled up in Peter's heart, and a deep voice rang out behind him.

"Great, I was just thinking about how to get you out of Ron's covers..."

Peter turned his head sharply, but saw only a blinding spell light, and then he noticed that his body had become very weak, as if he had not eaten for days and nights, and could not speak.

Peter watched in horror as Ivan approached step by step, and then felt his tail lifted, and he could only wave his paws weakly.

Click...

Ivan opened the door to the dormitory, and walked out of the dormitory with the gray-black rat in his hand, towards the room on the eighth floor.

Peter struggled for a while, and after finding that it had no effect at all, he had to reluctantly give up the idea of struggling, and obediently stayed in Ivan's hand and looked around tremblingly, not knowing where the little wizard in front of him was going to take him so late...

Ivan muttered to himself after walking three times up and down the wide corridor on the eighth floor, where many portraits were hung.

I need a room to make potions!

The next moment, a beautifully decorated door appeared out of thin air on the flat wall, and Ivan opened the door with familiarity and entered the room of responsiveness.

Peter's eyes widened, and behind the door was a huge space, which looked a bit like a Potions classroom, with a crucible on each rectangular mahogany table, gurgling some kind of potion boiling, and steam coming out of the cauldron...

When he was a student, he often explored the ancient castle with Jaime and Lupin, looking for hidden secrets, Peter thought he knew enough about the castle, but he didn't expect that there was such a magical place that they had never discovered.

Ivan casually tossed Peter to the side of the corner, ignoring him and instead went to check on the potion.

Anyway, when he finally left, he would use the Oblivion Charm to cleanse Peter's memories and make him forget all about it.

Peter didn't know that he had no secrets in front of Ivan, and he still had a hint of luck, thinking that no one should be able to see through his Animagus, which was nothing more than a guinea pig to test potions.

Peter comforted himself in his heart,

At this moment, there was a sudden sound of something breaking in the silent room.

Peter turned his head to look and saw that one of the cauldrons had burst, and the cloudy juice had spilled on the wooden table like sulfuric acid and cauterized a large hole, making a sizzling sound....

Peter watched this scene and swallowed with difficulty, tears about to fall...

He felt like he might not survive today...

"Sure enough, adding a blackstone powder compound decoction will turn into a deadly poison." Ivan looked at the crucible that had suddenly burst open, and was not surprised.

This validates what Snape had told him before, except that the potions had been brewed a few days ago, and he hadn't had time to remove them yet.

Ivan walked over to each of the cauldrons, checked the potions, and then loaded the potions into the reagents in batches, and walked towards the gray mouse in the corner.

Peter was startled, and he tried to curl up his body, trying to reduce his presence, but it obviously didn't have the slightest effect.

Seeing Ivan getting closer and closer, Peter was in a hurry, and he let out a terrible scream, and his body suddenly twitched violently. Finally, he slammed his legs up, foaming at the mouth, as if he was seriously ill, and tilted his head and fell to the ground...

He felt that he was so miserable, and the little wizard in front of him would never abuse him again.

Peter's superb acting skills amazed Ivan, of course he knew Peter's physical state, he ate and slept every day, and ate when he slept, and he had been a mouse for more than ten years without illness and pain, how could he be just sick now.

Besides, even if you are really sick, it doesn't prevent you from drinking compound decoction, right?

Ivan took a few steps closer and stared at the gray-black mouse's head with his wand, and the magic penetrated into it, "seeing" the power that protected the spot around Spotted's head, and then increased the input of mana again.

Although Ivan would not lift the Animagus' anti-curse, he was an Animagus himself, so he knew exactly how to force Peter to change back to his original form.

After a while, the gray-black mouse was shaking again, more intensely than before...

Peter, who was pretending to be dead on the ground, was in agony.

What frightened Peter even more was that his body began to twist and deform, his hands and feet kept stretching outward, and his head became bigger and bigger....

This feeling Peter still vaguely remembers after more than ten years, the Animagus that represents him has been lifted...
