For several days after Halloween, the students talked about the attack on Mrs. Loris, without talking about anything else.

Gradually, since there were no new attacks after half a month, the students' enthusiasm for the matter began to wane.

In addition to the Harry Potter trio, there is another small group of students who have been investigating this matter.

Half of the members of Zhang Xu's group to brush Quirrell last year were seventh-grade students who were about to graduate at that time, and they graduated after the end of the last semester, and there are still more than 20 people in the school now.

Among the three major irons in life, there are students who have been through the same window and carried guns together, and these are the students who have experienced these two irons together, and the relationship is naturally different from other students.

After the start of this semester, more than 20 people who are still in school still often do activities together. Soon, they formed a small group of members from the four colleges.

When everyone was naming this group, Zhang Xu, who was writing a letter to China, casually said "tea time after school" to Zhang Qiu, who came to ask for advice, and everyone thought it was good, so the group was called this name.

This result made Zhang Xu have a little stomach pain.

"Tea time after school" is a relatively loose group, usually a group of people get together at a specific time when they are free, and they also do activities such as drinking tea and gossiping, reading books and newspapers, food tasting, playing table tennis, asking for marriage and making friends, and learning and mutual assistance. Everyone has no leader, and when something happens, just select a few people to take the lead. If members have the right friends, they can bring them together for the event. Group members also have their own standards for bringing friends, and those who are too poor are embarrassed to bring them. As a result, in less than two months, the group had grown to nearly fifty members, and almost all of Hogwarts students were included. However, the Harry Potter trio rarely attends events.

Such a loose group, Dumbledore could not be seen.

After Mrs. Loris's attack, the "Tea Time After School" started the general mobilization mode of the whole group, led by a few students who were prefects, and began a large-scale investigation.

To Zhang Xu's surprise, everyone's investigation was actually very reliable, and the progress was much faster than that of the Harry Potter trio.

For most of the month, the members of "Tea Time After School" confirmed from their family's historical materials that the secret room was the secret room left by Slytherin, and everyone also investigated that the secret room was opened once fifty years ago, and the original victim was the crying Myrtle, and the suspect was Rubeus Hagrid, and the possible locations of the entrance to the secret room also included the bathroom where the crying Myrtle was.

As for the things in the secret room, everyone also listed several possibilities, including a bunch of magic items that Zhang Xu had never heard of, and magic monsters including basilisks.

It's just that the descendants of Slytherin have no reliable claims. They have investigated the genealogies of the students and professors in Hogwarts, even Filch, Lady Pomfrey and Lady Peaces.

After all, there is great power in numbers, and only Hermione is the only one in the Harry Potter trio, and there are a lot of people who are top students. And they can also ask for help from the family, many of the members of the group are from the magic family, and there is an old man in the family who studied in the school fifty years ago, and after writing back, the old man of the family has told them everything that happened back then. A student's home in the Snake Academy even sent a copy of the Ministry of Magic's investigation into the murder in the secret room.

I couldn't help but feel so concerned about this matter, because they knew how powerful such a student body was. Voldemort's team, the Death Eaters, relied on the students who were in the school. If the group continues to grow, it may become "Tea Time for the Ministry of Magic" in the future. If one's own children can occupy a place in this group, their role in the future is limitless.

At the moment, it seems that as long as Harry is found out to be a parseltongue, and then the faucet is found, then there will be nothing to do this year, and everyone will be happy to eat hot pot.

The progress of the matter made Zhang Xu have a little stomachache, the previous considerations were in vain, and now he doesn't have to bring the rhythm by himself, and he runs all the way by himself.

Zhang Xu seems that this is all because the students of Hogwarts are too idle to play Sherlock Holmes games, and they are about to clear the level at once.

When he first arrived at Hogwarts, Zhang Xu felt that the campus life of the students here was so monotonous.

There is no morning reading, no evening self-study, no quizzes, no section exams, no extracurricular tutorials, and not much homework.

It is a little uncomfortable for students like Zhang Xu who are accustomed to fighting in the sea of fighting questions. Think about your last life, night outing at school? Wouldn't it be nice to have the energy to make two more papers?

At that time, the media vigorously boasted that Zhang Xu's generation of "examination-oriented education" was extremely backward, and in the long run, the country will not be a country.

As a result, in the blink of an eye, the average age of the "Chang'e Project" team is in their thirties, the average age of the large aircraft R&D team is in their thirties, and the average age of the high-speed EMU R&D team is still in their thirties.

Hogwarts has no extracurricular activities. One Quidditch, the regular team of the whole school plus the substitute team is more than fifty people, and the rest are watching.

Teenage students are full of energy, and if they have no place to vent their energy, they can only violate the school rules.

If the professors were asked to increase the amount of homework by three to five times, Harry and his father would not have the energy to toss Snape back then, and maybe Snape would be able to marry his childhood sweetheart.

However, that all started to change this semester.

During the summer vacation, Professor McGonagall visited the Chinese School of Witchcraft and Wizardry from junior high school to university, and since school ended in early July in England, Professor McGonagall caught up with the end of the term.

Then Professor McGonagall was shocked.

Professor McGonagall, who returned to Hogwarts with shock and thought, told Dumbledore and the other professors what Huaxia had seen and heard, and the others fell silent.

Later, Dumbledore wrote a long letter and sent it to Zhang Xu.

The contents of this letter became the subject of speculation among British historians for a long time afterward. It wasn't until many years later, on the thirtieth anniversary of Dumbledore's death, that Zhang Xu made the letter public. Since then, students in the UK have one more history question that must be examined.

As the new term begins, the students at Hogwarts notice some changes in the school.

In terms of school rules, the school has relaxed the management of nights, and the curfew time has been changed to 10 o'clock on weekdays and 12 o'clock before holidays.

In the after-school activities, the table tennis (magic version) that Zhang Xu brought to Ravenclaw was promoted by the whole school. The school also hinted that students could do more of their favorite leisure activities.

Immediately afterwards, the students found that the new books brought by Zhang Xu in the reading room also included more books on Muggle history, literature, society, economics, military affairs, and technology. To Zhang Xu's surprise, the most borrowed among them are detective novels such as Sherlock Holmes detective books.

Eventually, the students discovered that the school had a new course called Mathematics. The course was taught by a member of the magical family that had taken refuge in the East during Voldemort's rebellion.

Through these changes, Zhang Xu can predict that many years later, the British wizarding world will face a more violent turmoil than Voldemort's troubles.
