"Is it a two-way mirror?" Felix asked with interest.

"No, Felix, I don't think so." Flitwick pondered.

Professor McGonagall expressed his guess: "Maybe it's a magic newspaper?"

"Newspaper?" Felix looked at her. He had never thought of this thing.

"Yes, I remember that the Daily Prophet has similar technology. If the news changes, the content of the newspaper will also change," Professor McGonagall added. "Now this situation is rare. They prefer to move to the evening newspaper of the day."

She recalled, "During the war years, the Ministry of Magic used the Daily Prophet to issue several emergency notices..."

Felix was a little surprised. In his impression, the Daily Prophet did not follow the integrity of the news very much. They might be more concerned about the sales of newspapers.

That's why the daily and evening newspapers, as well as the weekend edition of the Sunday Prophet, are divided.

But the views of the Daily Prophet are generally inclined to the Ministry of Magic, so... Is this the basis for cooperation laid a long time ago?

"Did they also use synchronization magic?" He wanted to know more information.

"I think more than that - the newspaper may have used a variety of transformation spells. This is their exclusive technology and cannot be seen in other newspapers." Professor McGonagall replied.

Felix thought about it. In this way, it is indeed similar to his answer parchment, and even more complete - their newspapers cover the whole of Britain.

Except for the lack of interaction.

"No." Flitwick said in confusion, "Strange, I shouldn't have forgotten..."

Professor McGonagall's eyes widened, and she interrupted him stutteringly: "Could it be that person's mark, Filius?"

"Oh, God, of course not!" Flitwick's voice became sharp.

Felix listened quietly. Are they talking about the Dark Mark?

He has not studied it, but his impression is that it is a kind of magic contract with a pattern, which has the function of positioning and summoning. Maybe Voldemort has added his personal understanding?

Belby, who was silent at the side, suddenly said: "Come to think of it, I have seen something similar in the Muggle world..."

"Yes, that's it!"

Belby's words gave Flitwick inspiration, and he said in surprise: "I remember, I heard about it from Professor Bubbage."

Caridi Bubbage?

Professor of Muggle Studies?

Felix recalled that he had not met this professor many times, and she seemed to live off campus all year round.

"Caridi showed me a picture, it was square, I don't remember its name." Flitwick looked at Belby, hoping to get a response -

"Oh, I remember it was called a mobile phone?" Belby said: "I saw someone using it in the Muggle Opera House, and I asked him about it. I said I was from the countryside."

He grinned at Felix, which was mentioned in the "Methods for Dealing with Muggles" given by Felix in his book.

Flitwick gave Belby a look of affirmation, "That's it~ mobile...phone? It is said that Muggles can communicate across thousands of miles. Caridi complained to me that her paper was ignored. They thought it was a fantasy - it was all antiques."

Professor McGonagall didn't know much about Muggle items. She asked in confusion: "Is the Muggle world so developed? How do they solve the problem of long-distance communication?"

This time, Flitwick and Belby were speechless. Their understanding of this aspect was very limited.

Felix exhaled lightly.

He knew what kind of book he should write this year - an introduction to the technology of the Muggle world. However, Professor Bubbage's experience gave him a good counterexample. If he started with something beyond the imagination of wizards, he would not be able to make any waves.

The two books he wrote before introduced the development history of ordinary people and their way of thinking, which were things that wizards could understand. Moreover, he deliberately arranged a large number of examples of communication scenes, which were relatively practical - it was convenient for some public officials to follow the map and deal with ordinary people.

Because of this, his book can be recognized by professionals.

It would also be convenient for him to include some personal opinions that he really wanted to say...

How should he organize the structure of the new book? Felix thought.

'It must be simple, clear, and easy to understand. It's better to have more than less. '

Some simple mechanical parts, some prototypes of energy utilization, or even simple and repeatable physical experiments...

He suddenly remembered that when he talked to Miss Granger about Lockhart, he mentioned that he admired Lockhart's method of incorporating knowledge into the story. "Maybe I will imitate him in the future!" He said to his assistant at the time.

Now it seems that he can write a fairy tale of "The Adventures of the Wizard Boy"?

"Felix?" Flitwick looked at him.

"I just thought of some interesting things." Felix said.

He put the matter of visiting Professor Bubbage on the agenda.

As for the improvement of the answer parchment, he still had many little wizards' brain holes that he had not brought out. In addition, the two-sided mirror, magic newspaper, Dark Mark, and mobile phone could bring him inspiration and ideas.

Halfway through, several professors finalized the cooperation plan. Belby felt a little regretful. He was not good at this at all.

After the dinner, the young wizards left in twos and threes, tacitly. Some male and female wizards quietly disappeared from the main group and went to find a secluded place for a date.

'I wonder how many young couples Filch will catch tonight?' Felix's mind was spinning with random thoughts.

Back in the office, he flipped through today's "Evening Prophet". The front-page news on it caught his attention -

'Gilderoy Lockhart faces seven years in prison, and fans write letters to criticize the Ministry of Magic.'

This aroused Felix's interest. The newspaper mentioned that Lockhart deeply regretted his actions and was willing to treat and compensate those who were hurt - hoping to escape punishment.

He also took out a full 20,000 gold galleons and donated them to various prestigious magic organizations. But the Wizengamot still sentenced him to seven years in prison - from Felix's point of view, this sentence was obviously reduced.

Besides, the Dementors that ordinary wizards fear are not that scary for the memory master.

But for Lockhart, losing his dazzling halo and future is the most terrible punishment, right?

But this is not the most outrageous news today. In the corner, he found an inconspicuous piece of news -

'The former editor-in-chief of the Daily Prophet, Rita Skeeter, faces charges of long-term concealment of Animagus and illegal acquisition of others' secrets for personal gain, but recently, the Ministry of Magic suddenly withdrew all charges and sentenced her to a fine of 2,000 Galleons. It is reported that more than one senior official of the Ministry of Magic said that there is no direct evidence to prove that Rita Skeeter is guilty...'

Felix suddenly laughed: "Rita, Rita..." He was really eye-opening.

Gilderoy Lockhart and Rita Skeeter, they are very similar to some extent. They both became famous wizards and witches by illegal means.

Lockhart even won a third-level badge of the Order of Merlin, representing honor.

But even so, when the crime was exposed, their endings were completely different - Lockhart was given a commuted sentence, but still went to prison; while Skeeter's sentence was not painful.

Felix's light blue eyes reflected the night view of Hogwarts in the night sky. He was very curious at the moment: "How many secrets of big shots do you know, Rita Skeeter?"

A string of controversial names of high-ranking officials in the Ministry of Magic flashed through his mind -

Cornelius Fudge, Barty Crouch, Ludo Bagman, Dolores Umbridge, Pius Thicknesse...
