Soon, Halloween is coming.

Pumpkins hang everywhere in the castle, and the hallways smell of roasted pumpkins smell sweet and enticing.

Everyone was looking forward to the Halloween dinner party, which would be as lavish as the opening party.

In this atmosphere, everyone is unsettled and cannot concentrate on the lecture.

In order to increase everyone's interest, Professor McGonagall taught everyone how to turn objects into moving pumpkins in Transfiguration.

Although it was a bit beyond the level of the students in practice and a little difficult to learn, Professor McGonagall didn't expect them to succeed directly, so everyone had a great time.

Well, this kind of happiness has even infected Xiao Yiren, who has been busy in recent days.

In the past few days, since the compound decoction has been boiled and the effect has been verified, Xiao Yiren has also begun to let go of himself and began to study other things.

Originally, Xiao Yiren was still thinking about whether to try to carry out the Animagus transformation during this time.

But after looking at a large number of books in the library, such as the Animagus Transfiguration Records and Professor McGonagall's experience, Xiao Yiren gave up on the idea.

The Animagus is an extremely complex form of magic, with a rigorous and complex series of steps in between.

For example, the initial preparations:

For an entire month, a single leaf of a mandrake must be held in the mouth continuously. The leaf should not be swallowed or taken out of the mouth at any time, and if the leaf leaves the mouth, the whole process must be started again.

But beware...... This preparation is after you have practiced magic sufficiently.

It's like preparing for the college entrance examination, you have to have a physical examination and you have to register, but it doesn't mean that you can be admitted to a certain university if you do all of this.

Before that, you have to go through many years of training.

The same is true of the Animagus, where you have to practice the transformation in private, and the part of the transformation is your own body.

This also means that during this period, Xiao Yiren can hardly do anything else, but for the time being, Halloween is almost the outbreak period of the entire Harry Potter world, and what trolls, what secret rooms, and what Quidditch will basically be here.

During the gathering time in the hard-hit area, something could happen at any time, so it was naturally impossible for him to do such a self-binding thing.

Therefore, he shifted the focus of his research for the time being, and began to study high-end spells, potions, alchemy, and ancient magic scripts.

Then Xiao Yiren was very successful in keeping his busy feet from touching the ground.

Of course, even if he is busy, Xiao Yiren can't be so busy on Halloween that he can't see a shadow.

No, even now, even if he had never heard Professor Sibin's history of magic class before before and fell asleep after listening to it, Xiao Yiren was lying next to Hermione's table without leaving an inch, chatting in the group, and ready to keep up with Hermione, who might rush into the girls' bathroom and be blocked by the troll.

Mao Yiren: "Halloween has begun, and the trolls are coming. (˃⌑˂)”

Xiao Alien: "Labor and management can finally see the light of day!! ＼(`Δ’)／”

Mao Yiren: "Don't think about it, wasn't the unicorn you booked before?" The troll appeared in the Harry Potter timeline on October 31, 1991, and the timeline for the death of the unicorn is after the appearance of the fire dragon Nobo, that is, after the Harry Potter timeline April 24, 1992. -.-”

Mao Yiren: "Or do you want to try out the troll genes?" -.-”

Xiao Alien: "......"

Xiao Alien: "Can't you make me happy in advance!" Bastard. ('dish ́)"

Xiao Alien: "Alas, smart coral brain is not equal to absolute memory, and the timeline thing was also used once before when I was writing a novel, and I can remember it clearly." ￣へ￣”

Mao Yiren: "Oh, by the way, anyway, I have absolute memory ability for the events in the Harry Potter world, so I didn't back up my memories to you, but I was negligent...... (； a_a)"

Pai Daxiao: "This is really, in my previous life, I read a fanfiction troll and it was a unicorn not long after, and if I don't know the time specifically, I guess it may not be clear that there is a full half a year in the middle...... (ー_ー)!!”

Mao Yiren: "Come on, I can't forget it anyway, so I won't send it, I'll retire first, and the history of magic is out of class......"

……

Harry Potter World, Hogwarts.

Being held in Hermione's arms, Xiao Yiren only felt that something seemed to be wrong with the slightest thing.

"No, little Hermione, why are you walking so fast? You can't hear Ron's complaints, don't go to the women's bathroom, don't run into trolls, how can I pick up corpses?! How can a hero save beauty?! ”

Complaining a little confusedly, Xiao Yiren nodded a little helplessly, wanting to see what happened to Hermione's side to make the plot change like this.

"I knew that I should eat more at noon today, but I blamed Wai Te, and I read a book with me, so I didn't eat much at noon."

"Wow~"

Listening to Hermione's heart, Xiao Yiren also felt that the top of his head was viciously rubbed twice.

Siu Yiren: "......"

"Is this my pot? Well, here's my pot ......"

Hermione's little guy's sense of victory and defeat is too strong, and even Xiao Yiren's cat is in his comparison target.

At noon, in order to ensure Hermione's safety, Xiao Yiren rarely followed the whole process, and after eating first, he watched divination next to Hermione, and then after Hermione saw it, he rolled it up, picked up the book like this, and didn't even care about eating.

"Good guy, it seems that these things that collide with probability can no longer be believed in the future, as long as a little external force is added, it is possible to deviate the original result of the matter......"

Shaking his head a little unpleasantly, he struggled to jump out of Hermione's arms, and stood at the door of the auditorium and glanced at Hermione a little unpleasantly, as if he said, "I don't want the black cauldron that fell from the sky."

"Forget it, it's okay like this, so I don't have to waste the compound decoction that I worked so hard to make......"

Then he went straight into the Great Hall and disappeared from Hermione's sight.

Seeing this, Hermione didn't stop it, for the past two months, this kind of casual messing around had been the norm.

Staying by Hermione's side like this today is an anomaly.

Of course, Hermione didn't worry too much, anyway, no matter how Xiao Yiren wandered around, basically as long as it was after class or school, it would reappear.

After all, in this "safest place" in the wizarding world, Hogwarts, how could there be any danger.
