The final semester is finally coming to an end, and tonight is the question of the ownership of the House Cup, and then tomorrow we can go back to our respective families to have a happy summer vacation.

Of course, it's hard to say what exactly this summer vacation will be like for Harry. Maybe there's a not-so-good-looking elf that will cause him a little trouble.

Li Yi locked himself in his room.

This world is finally different from the book, and these people in front of him are not just NPCs reading their lines, they are living people, with joys and sorrows.

Although Li Yi felt that he was a normal person when he was in the original world, he didn't know why he felt that some of his feelings seemed to be slowly moving away from him.

Looking at the little guy flying awkwardly on the table, it was now slender, and it seemed to be more and more different from Noble.

"Forget it, there's no need to think about it." Li Yi shook his head, as if he wanted to shake these strange thoughts out.

He took out the results of his semester's experiments from his desk, it was a tube of bright red liquid, which seemed to be the same color as blood, but in fact, most of the reagents in this tube were plant-based materials, and when Li Yi stimulated them through magic and technology, almost all of them turned bright red.

Then he scraped a little bit of the Philosopher's Stone onto the other side of the small square of paper, and gently shook a little powder into the other free test tube.

Finally, he took out the specially equipped potion for examination from the drawer and dripped it directly into the test tube containing the Philosopher's Stone powder.

A puff of red smoke emanated from the test tube, which was immediately sucked up by the extraction device.

After about a minute, there was no more smoke in the test tube, only a little red crystal, which seemed to be only transparent to the Philosopher's Stone.

Li Yi looked at his efforts in the past semester next to him, looked at the remaining magic stone powder next to him, sighed softly, and then packed them all in a special preservation device.

The inside is almost vacuum, which is useful to prevent the chemical from changing due to the environment.

Got up, walked around his room, and looked at the dazzling array of experimental instruments, both magical and technological, which looked a bit mixed and matched. With a wave of his hand, he put everything where it should be, then used a cleaned up and left the house he had lived in for nearly a year.

He won't be staying here for a while during the summer holidays.

When he first came to this world, Li Yi just thought that he was just reliving his life, and he only used the advantage of being familiar with the times to contribute to his future good life; Later, when he learns that this is the world set in Harry Potter, he becomes interested in magic again; Now, however, all he had left was research in his head......

Originally, he was still worried about his strength, but since he found that his magic began to grow explosively and seemed to have no side effects, he began to be interested in the magic of this world.

I just wanted to complain about Hogwarts raising a future scientist into a mysterious witch, but I also began to be fascinated by the world displayed by modern technology......

The little guy was the only one of them who succeeded, and the rest of them didn't know why...... Li Yizi, who thought he had learned a lot, knew at that time that the more he learned, the more problems he had, and this was a process that people enjoyed extremely much.

Identify problems and solve them. This process made him happy.

Then the original expectation of the plot, that is, the expectation of the holographic movie, disappeared without a trace.

His understanding of Hermione has also changed from the original Audio-Technica Miss Jack-of-all-trades to a qualified researcher and a studious seeker.

……

The door rang, interrupting Li Yi's thoughts.

He got up and opened the door, and outside the door was his companion, Hermione Granger, who was on his way.

"Hermione, is the banquet about to begin?" Li Yi was a little stunned, and now his thoughts were still a little floating.

"Not yet, but Sige, I've found a good place!" Hermione seemed to be a really twelve-year-old girl at this time, looking sunny.

A ray of sunlight cast outside the house from the window in front of the castle, somewhat bright.

Following Hermione to her so-called good place, Li Yi found that he actually knew about it.

Looking at the surrounding decorations, the tapestry of the troll stick beating the fool Barnabas is still hanging here, but in the portrait of Barnabas, he is missing, he should have gone to the door.

"Hermione, this is the Room of Need...... What did you find? "Li Yi didn't know exactly what Hermione had said in front of the Room of Requirement. This magical house always fulfills people's wishes. Of course, there is basically a logical desire, and it also has its own ceiling.

However, although the capacity of this room is limited, Li Yi feels that there should be at least thousands of rooms in it, and he does not know which interesting thing Hermione is talking about.

"I found a magical room just when I wanted to put something...... I was saying, 'I need a place to hide,' and then the magical room appeared in front of me, with a lot of interesting things in it. There were tall bookshelves full of books, and a few other things that seemed to be left over from Hogwarts a long time ago. I didn't look closely, but it's definitely a great place to explore and we might find something useful......"

Hearing Hermione's words, Li Yi closed his eyes and thought about the information in his mind about this "place to hide things" room.

When he opened his eyes again, he already had an idea.

"Alright, Hermione, we might be able to go in and have a look. What is in the Hogwarts Collection, maybe we can see some words of history.

……

The door to the Room of Requirement opened again, and Li Yi and Hermione walked out again, looking in a good mood.

"Hermione, it's the final dinner of the semester in a minute, we're going to hurry up."

Saying that, Li Yi's walking speed increased slightly, and it seemed that he was in a good mood.

Walking to the auditorium, it was full of laughter and laughter, and the joy of the holiday filled the whole room.
