Take Uncle Nine to Hogwarts

......

"For Santa's sake, you won't be deducted points, and you will be fined to go to the Potions classroom to scrub the cauldron! Remember that magic is not allowed! Use the Muggle way, use a rag a little bit, carefully Wipe all the cauldrons clean for me..."

"How about a point demerit? We're still waiting for the Christmas dinner!"

"Shut up Ron!"

Harry hurriedly grabbed Ron, and apologized to Professor Snape:

"Good professor, try it, after we wipe it clean, you won't lose points!"

"Under my supervision, if you can pass the test, of course I will not deduct points."

Professor Snape looked at Harry and Ron in front of him, and naturally guessed whose handwriting it was, but he still asked knowingly, "By the way, tell me, what exactly is going on with you?"

"It's our brother Li Xian's punishment."

Ron explained: "He said we don't know the rules!"

"He punished very well!"

Professor Snape said with an approving expression: "It's just that the punishment is too light! Now immediately follow me to the Potions classroom and wipe the cauldron!"

When Hermione arrived after hearing the news, she only saw the backs of Harry and Ron being taken away by Professor Snape.

Especially when you see their clothes...

"what's the situation?"

At this time, Li Xian, who came out of nowhere, said with a smirk on his face: "Professor McGonagall just taught me the experience of transfiguration. It mentioned that the spell of changing clothes is very interesting. I couldn't help but take it." Two junior sisters, Li and Ron, experimented."

While speaking, Li Xian handed Hermione the Transfiguration experience that had been transcribed, but Hermione saw right through Li Xian who had been dormant here all this time: "I think you did it on purpose."

"Do you want the experience? If you don't want it, I can take it away!"

Li Xian pretended to take it away, but Hermione snatched it back immediately.

"If Professor McGonagall knows that you use what she taught you to conduct experiments on Gryffindor students, what do you think she will think?"

"He will praise me for my superb skills!"

Seeing Li Xian's mean face, Hermione became even angrier. Originally, she wanted to ask him to act together tonight and sneak into Slytherin... Now this idea has been completely dispelled .

And Li Xian also inadvertently got rid of the fate of not interfering with the progress of the main plot...

But it made Hermione very anxious... Seeing the night fall, when Harry and Ron didn't come back... when Hermione decided to go directly to the Potions classroom.

Harry and Ron are finally back too...

"Professor Snape let you go?"

Hermione looked at the two in disbelief, and their clothes had changed from Christmas maid outfits to Gryffindor hospital uniforms.

Harry explained: "Well, after the effects of Maoshan Transformation and Wizard Transformation disappeared on us... Snape let us go."

Ron added from the side: "You said you hated us as soon as you saw us, and ended up staring at us cleaning the cauldron the whole time."

Hermione asked curiously again: "Have you finished wiping the cauldron?"

"How is this possible? There are so many crucibles? I can't clean them all in a year!"

Ron complained, but Harry said without any danger: "Fortunately, Professor Snape didn't deduct twenty points from us!"

"Okay! It's almost time!"

Hermione said to Harry and Ron, "Let's sneak in while most of the Slytherins are in the Great Hall for Christmas dinner."

Afterwards, the two went to the bathroom on the third floor where Myrtle often haunts.Hermione quickly brought out the prepared four cups of compound soup...

Ron asked suspiciously, "Why four cups?"

Hermione hesitated and explained, "Just in case, I prepared an extra copy."

Then he put the cup aside, and put the hair of Gore, Crabbe, and Millis they had prepared in advance into it.

As a result, Harry and Ron successfully transformed. As for Hermione who hid in the bathroom cubicle and refused to come out, in desperation, Harry and Ron had no choice but to set off first.

Just after the two left...

A mean laugh entered Hermione's ears, and Hermione was instantly alert.

"You are not allowed to come over!"

"Brother's medical skills are very good."

"I said, you are not allowed to come over!"

"Do you want to be a cat all the time?"

"How do you know I've turned into a cat?"

Hermione looked surprised. Does Li Xian have the ability to see through?

At this moment, Li Xian also found the remaining fourth cup of compound decoction. At this moment, he suddenly realized what he had missed by accident... Immediately rejoiced secretly, and then said to Hermione:

"Do you know why you made such a big mistake this time?"

Although Hermione is anxious to let Li Xian go away at this moment, she knows that Li Xian is imparting her own experience at this time, so she will naturally not refuse.

Just listen to Li Xian's explanation:

"You are very smart, but you often ignore some small details. The hair of a cat is so thin and soft, so different from human hair? If you pay attention a little bit, you will be able to tell the difference... How can you make a mistake? , turn yourself into a cat?"

When Hermione heard this, she immediately regretted it.

That's right!How could I have neglected such a small detail?

Just when Hermione was grateful for Li Xian's reminder, the senior brother Li Xian started to smirk again:

"Or do you Gryffindors like to change cats for nothing???"
