Neither in the morning nor at noon did Vid see Dumbledore. He thought Dumbledore would return to school before dinner, but during dinner, the principal's figure was still absent from the teacher's table.
Vid sent a message in the Friendship Book, but there was no reply. He started to feel worried.
Logically, four vampires could not possibly pose a threat to Dumbledore, but what if?
Those people possessed something that could make a werewolf transform early, and there might be other weapons.
Vid was preoccupied throughout the time that followed until Harry found him.
On Saturday during breakfast, Harry approached Vid and whispered, "Vid, later on I want to use the Disappearing Cabinet to go to Hogsmeade."
The Disappearing Cabinet was housed in the Room of Requirement, and Harry knew this.
Vid had hidden many secrets there; even if he didn't use the Room of Requirement, there was at least one House-Elf inside doing some simple tasks, ensuring the room remained "online."
This greatly reduced the chances of someone inadvertently entering, even if someone accidentally guessed the "room opening password," the House-Elf would immediately notify Vid.
So far, this situation had not happened.
So when Harry wanted to use the Disappearing Cabinet, he needed to inform Vid first. Vid would then have the House-Elf exit the room, allowing Harry to enter the room where the Disappearing Cabinet was hidden.
"Going back?" Vid asked in surprise, then thought of something, his face slightly changing.
Sure enough, then Harry said worriedly:
"Remus hasn't replied to my messages. I asked Sirius, and their connection is also lost."
"I'm very worried… Could something have happened to Remus? Could it be the Ministry of Magic bothering him again?"
"Although Sirius also said he would come back to check and asked me to stay put at school, I still want to go have a look…"
"Sorry…" Vid apologized, "I know what's going on with Remus, but I forgot to tell you guys…"
Although only a day and a half had passed, Vid had used the Time Turner several times, making him feel that Lupin's transformation into a werewolf was several days ago.
He was preoccupied with wondering when Dumbledore would return and completely forgot to notify Harry and Sirius.
Harry was taken aback: "… Did something really happen to Remus?"
"A little…" Vid glanced at the students walking around the long table and whispered, "It's not convenient here; let's go out after dinner and talk."
Harry nodded absentmindedly, grabbed a pie and casually stuffed it into his mouth, saying he was full.
"No, you're not full." Hermione sternly said from not far away, "Don't forget you still have Quidditch practice today. Practicing on an empty stomach isn't pleasant."
It was the weekend, no need to rush to class, and Hermione could finally leisurely enjoy her breakfast.
Despite this, her book bag beside her was packed full, looking quite heavy.
Harry had no choice but to pick up the pie again and nibble on it casually.
Vid knew he was anxious inside, quickly finished his own breakfast, and the two of them left together. As soon as they reached the foyer, a student ran over, panting.
"Harry… Mr. Harry Potter!" The student looked admiringly at the young savior and said, stammering, "Professor McGonagall wants you to go to her office."
"Now?" Harry said, troubled, "I have something to do right now."
The younger student looked troubled as well: "But… Professor McGonagall said…"
"Go ahead, Harry." Vid said, "After that, you can find me in the library. I'll be available anytime today."
"Alright." Harry nodded and finally followed the student away.
Vid turned and headed towards the library.
In fact, he didn't have any homework to complete—
Among the twelve subjects, in Transfiguration Class, Spell Class, and Defense Against the Dark Arts, Vid's learning progress far exceeded his classmates, and several professors had excused him from doing homework.
The other courses, including Numerological Divination, were easy for Vid; he had mastered the vast majority of the knowledge, making homework very simple.
Magic History, Divination Class, and Muggle Studies were just where he spent time writing assignments. If it weren't for the few people in each classroom, making it quickly noticeable if someone was missing, he would have thought about skipping class altogether.
To maintain possession of the Time Turner, Vid always kept a full attendance rate just like Hermione.
Among his friends, Harry and Neville could never figure out how they managed it, although others had more or less guessed a bit.
Lately, Vid began researching ways to improve the Friendship Book.
Adding more features to a small piece of parchment was far more difficult than applying magic to a house.
After all, its capacity was limited, and if not careful, it could easily be damaged.
Therefore, even just adding a few features significantly increased the cost, while the sale price couldn't be dramatically increased; otherwise, consumers wouldn't be willing to buy it.
Vid didn't expect this parchment to become as multifunctional as a cell phone. Currently, he only wanted to improve the information storage capacity.
Originally, messages in the Friendship Book would automatically disappear after a period if not viewed promptly.
While casual group chats disappearing was no big deal, losing important messages caused significant inconvenience.
Additionally, the notification function of the Friendship Book needed changing.
For someone like Vid who didn't enjoy chatting, he often felt the Friendship Book heat up during the day, sometimes staying hot all day.
Opening it up often revealed content like House-Elves discussing the day's work or SSC members planning maze tactics, assignment focuses, and so on.
So whenever the Friendship Book heated up again, Vid hesitated—if he opened it, it might be a complete waste of time; if he didn't, he worried about missing out on important messages.
He decided to improve the flaw of repetitive reminders in group chat messages and then separate other messages by their importance level, distinguished by different ways of alerting, with the highest level emergency messages emitting a siren-like urgent and loud noise.
Finally, Vid planned to add an image transmission function to the Friendship Book.
Previously, the Friendship Book could only transmit hand-drawn pictures, but this time, he intended to change it so that as long as an image was clipped between two sheets of parchment, a few seconds later, the content would be imprinted and transmitted to the other side.
This was a feature some students in the school had publicly and privately requested Vid to add.
There was no ulterior motive; they simply wanted to copy assignments from each other during holidays, and were displeased that they had to transcribe the work onto the Friendship Book themselves after writing it out.
Vid thought about it and felt this function wasn't too troublesome and could also be used in the future to send photos to his parents, so he decided to add it.
