A certain Hogwarts professor of runes

After a long time—

Ginny finished speaking through tears: "Professor, will I... will I be expelled?"

"No, you can rest assured about that."

……

When Ginny returned to her seat with red eyes, Ron and the twins stared at her intently.

Ron tried to say something, but Ginny completely ignored him. She moved her little chair near Luna, who was humming a quirky tune in her ear.

For the remainder of the time, the twins were somewhat restless, but fortunately, Professor Hyp waved them away after they submitted their written suggestions.

"Ginny, what happened?" Not far from the office, George couldn't help but ask about his sister.

Ginny shook her head.

"Did Professor Hyp criticize you, Ginny? I mean, it was a bit dangerous for you to go into the Forbidden Forest, wasn't it, Fred?"

Fred replied without hesitation, "That's right. If you're interested in the Forbidden Forest, I can show you around... Actually, there's not much to do there, just trees, rocks, flowers, and plants."

She bit her lip tightly and refused to speak.

Luna and Ginny walked hand in hand, and she said in a singing voice, "Professor Hyp is quite easy to talk to, isn't he? But you do look unwell; I suggest you go to the school clinic."

"Thank you, Luna."

How did you know—

"Fred, George, and Ron, I'm fine. I just," Ginny said, taking a deep breath, "had a little trouble, but Professor Hyp helped me out."

Seeing that her brother was about to ask again, she said with a straight face, "I'm not going to tell you." Ginny then grabbed Luna and ran away.

Fred watched her retreating figure and said with a touch of emotion, "Ginny's grown up. She's not the little one who used to follow her brother around anymore."

George quipped, "So you miss the old days?"

"Well, the reason we reminisce is precisely to make sure we can never go back to the past, right?" Fred made a face.

The two of them started laughing and joking around.

The following week, Hogwarts remained as peaceful as ever.

Every night, the nine young wizards would report to the Ancient Runes Office and complete some tests as instructed by Professor Hyp.

In fact, most of them were confined on weekends, but Ron's confinement was a full thirty days long because of his "serious" actions and Lockhart's strong suggestion.

But when Professor Hyp promised them that subsequent detentions could be offset by the number of times they were detained, the other young wizards hardly struggled and volunteered to complete the entire detention process with him.

The reason is simple: other professors' work is all tedious and repetitive, while Professor Heip's work is the most interesting.

By the third or fourth day, they had formed a research group across colleges and were seriously discussing ways to improve the "answer space".

It wasn't just empty talk; it was genuine engagement.

Seeing the young wizards' enthusiasm, Felix was delighted and offered to provide guidance.

But as the sole technical advisor and judge, he had to reject one impractical idea after another, only selecting the parts that were easiest to improve.

"Young wizards, the professor is not omnipotent and cannot tolerate all your wildest ideas."

This is Professor Hyp's original statement when the twins suggested adding a "video call" function to the parchment.

Finally, at Felix's suggestion, the young wizards designed several different versions.

The most basic and original version was similar to the one they saw that day, except that different college logos were added and the feedback function was improved.

The twins and Ron played a huge role in this.

The feedback on the parchment can be roughly divided into two categories: praise for correct answers and criticism for incorrect answers.

The twins' sharp tongue impressed the other young wizards in their group, while Ron excelled at praising others, showering them with sycophantic compliments.

"Actually, these are all Lockhart fans' original words," Ron explained.

In subsequent versions, following Professor Haipu's professional advice, they completed a step-by-step iterative solution based on the level of difficulty.

The leaderboard was the most popular choice, which was easy to solve—he could use synchronization magic to compile all the information from the parchment onto the exquisite scroll in his hand.

This thing actually acts as a server.

However, it's not that intelligent; after obtaining the data, it needs to be manually sorted into high and low order.

As for other version features, such as online multiplayer, friend lists, and subject divisions, these are not things he can solve in a short time, nor can they be contained in a piece of parchment. Felix pushed them directly to the distant future.

By the end of this week, the twins, along with Graham Monta and Marcus Flint, had completed their confinement, but they chose to stay and finish the job.

The same goes for Ginny and Luna.

After learning of the research group's existence by chance, Hermione immediately asked Felix to let her join the temporary team.

With Felix's presence a deterrent, no one dared to openly mention the conflict between the academies; at most, they would show a mocking expression. But at this time, Professor Hyp's gaze would often follow them.

"I never imagined we could work together to accomplish something, and my second partner is a Slytherin!" Fred muttered to George one day.

"Hey, who would have thought? This is even more unbelievable than if we didn't cause some trouble at the end of the semester." George shrugged.

The twins' gazes fell on the Slytherin Quidditch captain—

Marcus, with his limited intelligence, couldn't offer any brilliant insights, but he essentially represented the lower limit of the young wizards. It was he who, as a pure tester, repeatedly discovered the bug in the 'answer space'.

Similar to the situation where someone asks, "Professor, why did the writing on the parchment disappear?" and the reply is, "Oh, you were thinking for too long, and it thought you were asleep."

On the morning of the tenth day, Felix got up early to prepare to go to the House of Requirement to complete his magic practice for the day.

He had only recently discovered the function of this room.

In fact, Felix had stumbled upon the Room of Requirement during the first attack, but he always thought it was a mysterious room where things were hidden.

The concealment magic applied to it is decent enough and worth studying. But this matter is actually quite low on his priority list.

It wasn't until Tom in the diary told him the real secret of the room that he regained his interest.

The Requirement Room can flexibly change its interior environment according to the user's ideas to meet the user's needs.

This almost instantly ignited his research desires, but Felix was unable to unravel the secrets of the room using his existing knowledge. He could only vaguely see the magical channels that filled the room through a hidden perspective.

"The magic supply of the Room of Requirement is rooted in Hogwarts Castle, which has stood for a thousand years."

This is Felix's idea.

Although his research was hampered, he developed a new use for it: practicing spells.

He could unleash his full power without restraint, including his instant-kill techniques. The benefits were obvious; at least, he no longer had to spend an hour traveling to the depths of the Forbidden Forest to practice.

……

As dawn broke, Felix walked down the empty corridor.

When he finished his training for the day and was about to go downstairs to the kitchen to find something to eat, he bumped into Lockhart.

He was dragging a large suitcase in his hand, with two smaller suitcases floating behind him.

"Professor Lockhart?"

The sudden sound startled Lockhart, and the two boxes he had been struggling to control fell to the ground with a thud.

"Who's there?" Lockhart whispered.

Felix descended the steps, looking Lockhart up and down. "Professor Lockhart, are you going out?"
