Hogwarts: The Cat Wizard of the Moving Castle.

Two weeks later, Harry and Luna came to Moon's office with the first complete spell manuscript.

The manuscript this time was well organized and was a full thirteen-inch long parchment roll. Generally, articles of this length were only seen in the homework assignments assigned by Professor McGonagall.

"So, you found the core problem of the instability of the magic spell that day?" Mu En asked in a low voice while looking at the article handed over by the two people.

"Yes." Harry nodded quickly.

Luna just hummed softly, as if she was in a daze.

Maybe not just 'like' either.

"Um"

A naive and to the point idea.

If it were within the magic system of this world, it wouldn't be so out of the ordinary.

After all, children who are not bound by rigid dogma will have an easier time getting to the essence of things.

Mu En looked at the modified spell carefully. Some of the pronunciation of the spell and the details of the wand waving were slightly changed from the original.

This, involving theory, is what consumes the most time.

After all, it is useless to only see the direction of change and speculate on the contradictions.

Put it down on paper.

"Not bad." Mu En nodded, and then pushed the homework back from the table under the expectant gazes of the two people.

"But it's still not good enough."

"I did say that you should treat the spell as if you were singing. But your treatment of the spell and the trajectory of the wand is like a third-rate singer adding tricks and transpositions to a good song that have no effect except to make the song better. People think it has no effect other than being noisy to the ears. When used as a spell, it has no benefit except increasing the difficulty of learning and affecting the effectiveness of the spell itself. "

At the same time, there was a knock on the office door.

"Come in." Mu En knocked on the table.

Then, the door was suddenly pushed open, as if the people outside the door were impatient.

"Mr. Jones!" Hermione's voice sounded anxiously.

Then she opened the door and looked at the two people sitting in the office in surprise.

Eh?

"Harry?" she whispered.

It's normal for Harry to appear here, but why would he appear here with this famous crazy girl?

"Miss Granger, please sit down." Moon raised her hand, and the twisted stone roots on the floor climbed upwards, and soon formed the shape of a chair.

Then, click——

Just like a fruit breaking away from its branches, it suddenly turned into an independent chair.

"Ah, Hermione, good morning," Harry greeted.

"Good morning." Hermione nodded, sat down next to Harry, looked at the huge manuscript that Moon put on the table, and suddenly understood.

"So, what you are doing is research on that curse?"

As she said that, she started brainstorming, but the more she recalled, the more blurred the memory in her mind became?

"What spell?" Harry looked at Hermione in surprise.

The Vulcan Curse that he and Luna were completing had not been told to Hermione.

"I can't remember the fire spell or anything like that," Hermione said hesitantly.

"Miss Granger." Moon's knock on the table pulled Hermione out of her thoughts.

Then, Mu En looked at Harry and Luna.

"You guys go out first."

"Okay, Professor." Harry and Luna nodded, and then Luna focused her eyes on Hermione.

"You've seen a lot of things, haven't you."

"Miss Lovegood." Moon smiled and interrupted her words.

Luna smiled sheepishly and walked out of the office with Harry.

In the corridor, Harry looked at Luna in confusion: "What do you mean by what you just said?"

"I don't know either." Luna shook her head.

"I just feel that there is something strange about Miss Granger, as if she has been washed away by something."

What Luna said was as incomprehensible as ever.

But Harry was used to it.

"Forget it, let's start modifying this curse, otherwise we will be late." Harry said.

The next revision path requires a lot of theoretical knowledge. For these two children, the work is not easy.

An accident is always going to happen, so I need to go to the infirmary.

"By the way, now that Hermione knows, do you want to ask her for advice?" Harry looked at Luna.

"Yes, of course." Luna nodded.

"Okay, let's go to the library and wait for her." Harry said.

Then, the two came

In the library.

A familiar figure was caught by Harry.

Hermione had messy long brown hair and some droopy eye bags. She looked listless, but she was concentrating on her book.

Harry walked forward, patted her shoulder, and whispered: "Hermione, when did you come up?"

"Huh?" Hermione was frightened by Harry's palm, and then turned her head.

"Oh, good morning, Harry," she said. "Why can't you come up?"

"She's confused," Luna whispered.

Harry nodded slightly. Even without Luna's strange seventh sense, Hermione could be seen confused just by looking at her face.

"It seems you've forgotten something again, haven't you?" Harry asked.

This isn't the first time this has happened.

Hermione behaved like this every time, saying 'Ah, um... yes, that's it'. '

Anyway, they used similar prevarication techniques to push Harry's questions back.

He really doesn't know anything.

"It's okay, we are here about a curse." Harry said instead.

At the same time, in the office.

"You saw the [Vulcan Curse] completed by Harry and Luna at the exhibition, right?" Moon said straight to the point.

"Exhibition?" Hermione tilted her head.

"I know you have a time turner." Mu En looked helplessly at the little witch pretending to be stupid.

After hearing his words, the little witch lowered her head in embarrassment and bit her tongue in embarrassment: "Um, okay, Professor. I didn't mean to lie to you. I didn't know."

"No, it's a trivial matter. Professor McGonagall asked you not to let others know about this matter, and you have kept this promise very well." Mu En nodded.

After hearing Mu En's words, Hermione raised her head again, and then wondered: "Professor, why did I feel so confused just now?"

"Because you want to tell Harry about the curse, right." Moon said.

"In a world with a single line of time, knowledge cannot be created out of thin air."

"Single-line time. Generated out of thin air?" Hermione frowned, obviously not understanding what Mu En said.

"It's very simple. Let's give an example." Mu En smiled, sat upright again, and took out a book.
