What made Ivan feel a little helpless was that, judging from the progress of his exploration of the Gryffindor common room and the men's dormitory, even if he had explored the three major colleges, he would not be able to push the progress to more than seventy percent.

In other words, he always has to go to one of the girls' dormitory and the basilisk secret room...

After hesitating for a while between life and discipline, Ivan decisively gave up the latter.

Tomorrow Saturday is the perfect opportunity for Hermione to go to the library to read a book.

Thinking of this, Ivan scooped up the potion in the cauldron with a spoon and put it into a transparent glass reagent, and then took out the brown hair in his pocket and threw it into the reagent.

The potion, which had been black and a little like sticky mud, suddenly bubbled out like boiling water, and it took a while to turn into a bright brown and precipitate.

......

Saturday morning,

Ivan, who had been waiting in the lounge early, met Hermione who was holding a book.

"Ivan, do you want to go to the library to read together?" Hermione greeted happily and asked.

"No, Ron asked me to go to the dormitory to play wizarding chess, so I won't go today." Ivan shook his head and politely declined Hermione's invitation.

The little witch was a little disappointed, but she didn't pay too much attention to it, and walked alone, continuing her daily study.

Ivan waited for a while, took out the map of the living spots, and made sure that Hermione was still in the library, and then went to the Room of Requirement, took out the polyjuice potion, and drank the brown potion in one go.

Kindness... The taste is ok....

Ivan smacked his mouth, somewhat surprised.

It's not the first time he's drunk a compound decoction, and judging from the description of the original book, this thing should be relatively unpalatable.

But he remembered that everyone seemed to have a different taste...

Before Ivan could think about it, he felt a tingling itch coming from his body.

It was the exact opposite of the last time he became Walker, Ivan was keenly aware that he was shrinking and shortening, the short hair on his head gradually stretched to his shoulders, curly, and the color completely changed from blonde to brown...

When Ivan opened his eyes again, he felt that the clothes on his body were obviously much looser.

Ivan drew his wand and tapped the nearest mahogany table, turning it into a giant full-length mirror through which he looked at himself.

The figure in the mirror looked exactly like the one he had seen Hermione.

Of course, there's something wrong with the clothes...

Ivan suddenly thought of this devastating question, he doesn't have a school uniform for girls!!

"I knew I might as well have gone to Tom to learn snake language and go to the secret room!" Ivan looked at "Hermione" in the mirror in the boys' school uniform and frowned depressedly.

But Ivan sighed, and finally resigned himself to using the Transfiguration Charm to modify his impression of the girl's school uniform.

Because Ivan wasn't sure if he could learn snake language on his own, he had the impression that Dumbledore could understand snake language by self-study.

Of the remaining ones, Voldemort relied on his natural bloodline, a talent passed down from his ancestors, and Harry was due to Horcruxes.

What's more, Tom is willing to teach two things.

"Well. It should be like this here, the skirt is too short, it is just right to get to the knees, and the collar in front needs to be changed..."Ivan tinkered with the Transfiguration Charm to try to restore Hermione's outfit as much as possible.

Fortunately, Hermione is not the kind of little witch who likes to dress up carefully, and usually wears a standard school uniform, otherwise, Ivan is afraid that he will have to give up.

After transforming his clothes, Ivan looked at the full-length mirror again, and always felt that the little witch in front of him was a little different from Hermione in his impression, and it took a long time before he patted his head...

A few books left!

......

In the morning, in the Gryffindor lounge, Harry and Ron are playing the deluxe version of wizarding chess presented by Ivan, the unicorn and Thestrals are fighting to the death on the small chessboard mountain, and from time to time you can see brilliant lights flying on the chessboard...

"Harry, your moves stink too." Ron commanded a Thestrals, kicking the whitebearded Dumbledore off the board.

I have to say that seeing this scene, Ron's heart inexplicably swelled with a sense of accomplishment, as if he had really won a wizarding war.

"It's Ron, your level is too good, next time you should play with Ivan." Harry put away the smashed pieces and shook his head helplessly.

"I'm going to have to find him, too." Ron complained helplessly.

In the past few days since the beginning of school, except for when he was in class and sleeping, Ivan was like he was missing, and he could not be found.

Ron was cleaning the chessboard, turned his head, and unexpectedly saw Hermione walking into the lounge from the outside with a book, and immediately asked out loud.

"Hermione, did you see Ivan today?"

"Huh?" Ivan was stunned, wasn't I right here?

Fortunately, Ivan immediately realized the change in his identity, recalled Hermione's tone, snorted lightly, and glanced at the two of them.

"How do I know where he's gone..."

After speaking, Ivan was embarrassed for a while, and always felt ashamed of learning from a little girl's tone, so he hurriedly quickened his pace and walked in the direction of the girl's bedroom.

Harry and Ron didn't notice anything wrong, but vaguely felt that Hermione's temperament was more impulsive today...

After moving away from the two, Ivan breathed a sigh of relief.

He hadn't expected to be so unlucky enough to run into Harry and Ron when he returned to the lounge, and they were still in the dorm room when he was checking the map of the living spots in the Room of Requirement.

But Ivan thought about it, and he shouldn't have shown any flaws.

Harry and Ron are unlikely to talk to Hermione about what they usually chat...

In fact, Ivan had thought about whether to use the polyjuice decoction to disguise himself as a girl he didn't know, but in the end he dismissed this idea, because if he met a close friend of the other party, it would be easy to goof.

And Ivan felt that he was familiar enough with Hermione to know that she didn't have many friends in the girls' circle, otherwise he wouldn't be messing with the three of them every day.

While thinking about things, Ivan had unconsciously entered the aisle of the girls' dormitory.

Groups of little witches walked past him laughing and laughing, mixed with the smell of various perfumes, and occasionally you could see a few frolicking junior girls...

Ivan didn't squint, he had come to explore this mysterious castle, but he just happened to be here...

Only when the other party takes the initiative to greet him, Ivan will smile and nod his head in response...
