"Lyle?"

Hermione looked over her pillow in confusion and found that she couldn't find the little snake, and she couldn't help but feel a little distressed, but she didn't worry too much. Green Snake has been running around since a few days ago, but she always comes back before dinner, and she doesn't worry much about getting lost.

It's just that it doesn't work this way! Isn't it already Neville's toad running around or something? In the blink of an eye, it will be out of sight...... By the way, I can't seem to find my library card? Did it fall in that place, do you want to go and get a replacement?

With a frown, the girl walked out with a book in her arms, looking a little sullen. She's been getting acquainted with the other Gryffindor students lately, and Ron is no exception - after all, no matter how arrogant the person who has been deducted points is, it is difficult to take it for granted that he has a bad attitude towards the main personnel who have been scoring.

In just this period of time, Ron and Harry have collectively deducted about fifty points, and Hermione has won back about that many points as a top student. In other words, Hermione has always been filling in the gaps for them, and even a paranoid person like Ron feels a little embarrassed.

……

……

Pei Chen was groping in the corridor on the third floor, he was now in human form.

And it has returned to the previous state of long-haired and green clothes.

He purposefully converses with the portraits on the walls to gain information. This world is indeed very wonderful, although the peak combat power is not very high-end, but it has gone very far in many fields, such as ...... The realm of the soul.

At least before this, Pei Chen had never heard of any portraits that could have the ability to act autonomously, they could run around, they could talk to other portraits and even living people, and they obviously had their own ideas! Except for living in a two-dimensional world, they are really no different from living people.

This kind of technology is simply unimaginable, and the craziest thing seems to be that the threshold for this technology is not very high. The vast majority of portraits and photographs in the wizarding world are of this type, and if you want to find a normal, non-moving one, it's a problem.

And after discovering this matter, Pei Chen was obviously concerned about this kind of technology - although the power system of magic conflicted with him, and he would never be able to master any of them without skill scrolls, but knowledge was different, and there would always be something in common.

He took Hermione's library card very decisively, and then with the bewitching effect of the demonic aura and the transformation of his appearance, he easily slipped into the school library - Mrs. Pince didn't even check it out, because he never lent out books, and always read them in the library.

After an in-depth understanding, Pei Chen found that the production technology of these portraits had already involved the realm of the soul, and it was a relatively deep level. It is said that in order to make such a portrait, it is necessary not only for the artist to have very strong supermagic skills, but also for the cooperation of the portrait himself.

――It is necessary for the subject to take the initiative to split a trace of soul into the portrait, and only in this way can the successful portrait have the memories and emotions of the prototype of the person at that time and most of the experience and knowledge, otherwise it can only be said to be a failure.

It is said that the ultimate goal of this technology is to create a Horcrux that will make people immortal. But I don't know if it's true or not, and Pei Chen can't get in touch with such a high-end knowledge system for the time being, so I'll put it aside for the time being.

Pei Chen's questioning is very skillful, and the objects he chooses to ask are all the kind of ancient portraits that have not been paid attention to for a long time, and the frames are all dusted, and most of the questions asked are the kind that are knocked on the side and will not involve some sensitive lines. For example, he would never touch a problem like the Dark Arts, even if it was only the most basic Dark Arts.

The portrait in this castle is also the eyes and ears of the owner in a sense, but the behavior of the line will not be discovered, and even if it is discovered, it will be tolerated, but it is easy to be noticed if it is too out of line, and it does not conform to Pei Chen's principle of making a fortune in a muffled voice.

With a yawn, Pei Chen ended his communication with the portrait, turned around and walked down the stairs to the third floor.

In a short time, he reached the end of the corridor on the right side of the third floor, and in front of him was a very tall door. It looks like it's heavy. This is exactly what Dumbledore announced at the previous opening dinner that he was not allowed to enter—it is said that anyone who enters it will suffer an accident and a painful death.

It didn't look like the principal was joking, so the students listened and enthusiastically tried it...... Yes, people are rebellious, and the more you don't let him do it, the more he wants to do it. As for 'an accident, a painful death' or something, come on, this is a regular school, how could such a thing happen?!

Harry Hermione and other first-year freshmen had to be brave and brainless, and just having to adapt to house life took up most of their mental energy, and they didn't know how many people were involved in such a thing in the past two weeks, and they didn't know what the subsequent development of events would be. However, Pei Chen has always paid attention to this.

As far as he knew, there were no less than double-digit guys who were brave enough to try, but nothing went - someone walked into an empty house, someone was teleported into a hallway next to the dining room, someone couldn't open the door at all, and someone went straight into the headmaster's office...... The results varied, but there were no tragic consequences.

In that case, what was the intention of the white-bearded old man to say that thing on purpose? Pei Chen was a little puzzled, and he also had a faint idea in his heart.

The old guy was probably deliberately targeting someone, like Harry Potter or something...... So, is he actually playing a big game? What an old fox!

However, no matter how cunning the other party is, it doesn't have much to do with Pei Chen, he doesn't even try, he turns around and leaves. If this place is really only set up for Harry Potter, then no matter how you do, you can't succeed, and if you push the door and enter the headmaster's office, it will be really a big problem.

The castle is often filled with students running around, some getting lost on their way to class, and some trying to find some castle secrets when they are free. Pei Chen passed by them so aggressively, and those students also turned a blind eye.

It doesn't take too many means, it's just a rudimentary application technique that emanates demonic energy, and you can purposefully confuse others, divert attention, and ignore your own existence. Although this is a low-level skill when the demon beast hunts, using the demon qi to paralyze the target, but it is enough to deal with these wizard apprentices who have a one-star rating to death.

Descending the stairs to the second floor, classes were already in place at this time, and there were very few students wandering around the castle aimlessly. As for the professor-level figures, there were originally few of them, and Pei Chen deliberately avoided them, but he didn't see a single one.

"Uh...... Flying lessons? Stopping, Pei Chen looked downstairs outside the window, a large lawn not far away. He saw several familiar figures, as well as the tattered brooms placed at their feet, and not only became interested, "Ah, it's already half past three in the afternoon!" ”

Because of Hermione, Pei Chen knew almost everything about the first-year students - only Gryffindor House, of course.

"Get up!"

There was another scream, but the tattered broom only rolled on the ground a few times before it regained its composure. Such a faceless behavior made Hermione's face a little embarrassed.

Although there were only a handful of truly obedient broomsticks, Hermione's was the majority, and there were not even a few like Neville's little fat man who didn't respond at all. But as a super student who dominated almost all subjects, Hermione still felt that if she couldn't do her best in all aspects, it would be unacceptable.

With great difficulty, she got the broom in her hand, and Mrs. Hooch began to give a lesson, demonstrating how to ride a broomstick without slipping off her head. As for the mutual provocation between Slytherin and Gryffindor, as long as it wasn't too much, she didn't see it, the feud between the two houses had a long history, and she didn't want to get involved in such a.

Hermione found that she didn't seem to have much talent for flying, so she sighed weakly, and when she raised her head slightly, she coldly met a pair of very familiar blood-colored eyes, and couldn't help but be stunned, and when she looked over again, she found nothing, and there was nothing in the window on the second floor of the castle.

Is it a delusion? How could Lyle possibly run that high?

The girl was a little confused.

……

……

"Ahh It's so dangerous, I'm almost seen......" Leaving the window quickly, Pei Chen plucked out his ears, there was still more than an hour before dinner, where are you going next?

To the Forbidden Forest? Forget it, this time has passed, and there will definitely be no time to come back, what if you anger the little girl and ban your feet in the future? Before there is no way out, Pei Chen does not plan to give up his pet identity, although it looks more humiliating. But compared to the mission and its own security, what can be counted as a mere loss of face? Don't look down on the Discipline Value of the Apostles of Time and Space!

Since the Forbidden Forest doesn't have time to go for the time being, let's postpone the plan! Try to find the secret passages hidden in the castle.

Pei Chen knew that this castle hid a lot of secrets, and the accumulation of thousands of years made its historical background incomparably rich, even the successive headmasters did not dare to say that they knew all the secrets of the entire Hogwarts castle.

Not to mention anything else, just the secret passage that I don't know for what kind of mentality and what reason was dug out, Pei Chen had already found three, one of which could sneak out of the school directly, and the entrance was hidden behind a certain statue on the east side of the second floor. There was also a broken abandoned secret passage, and Pei Chen didn't know where its final destination would be, because the amount of work required to re-dig a collapsed secret passage was simply too great.

The last one was too far away for Pei Chen to explore thoroughly, but it was certain that the exit was definitely at least ten kilometers away from the school.

In addition to this, there are several rooms where the secrets are also valuable. It was when Pei Chen was exploring before, there was a ghost named Peeves who ran out to make trouble, and after he grabbed a fat blow and beat him, the other party said the 'life-selling news' - not an exaggerated description, but just a story, if there is not enough valuable information, Pei Chen, who was suddenly drenched in a bucket of ice water, really didn't mind letting that naughty ghost die a second time.
