Harry put the letter from Dudley back in the envelope and put it away, intending to write to Rove Scamander, who was far away in the United States, to ask about the woman's situation before considering how to reply to Dudley.

He'd heard a guy say that he'd rather tear down ten Hogwarts than destroy a family affair, and help Dudley if he could.

Afternoon class time was approaching, and Harry had arrived at the door of the Transfiguration classroom a minute before class, but what he saw was the students gathered outside the classroom door chattering about the fact that the professors hadn't returned yet, and it seemed that he had just run over in vain.

Harry didn't bother the others, turned and walked alone to a room on the first floor.

The room had been empty for an unknown number of years, and even Peeves had no interest in entering it, until the beginning of the school year, when Professor McGonagall had the house-elves clean it and use it as an office for the newly formed department.

"Are you worried about Sirius and Remus?" Mad-Eye Moody asked, sitting behind his desk, looking down at something while he protended to be Harry, who was pacing back and forth in circles in front of his desk.

Perhaps it was the prosthetic eye that turned too quickly that caused the discomfort in the eye socket, and Moody looked at Harry for a while before looking at him again.

"They've been gone for so long, nothing should happen, right?" Harry asked Moody after he had already dizzed himself and sat down on a stool at his desk.

Moody's eyes moved away from the parchment on the table, and then he looked intently at Harry.

Moody's scarred face and two eyeballs, one real and one false, looked very intimidating, and even Harry, who was familiar with him, would feel uncomfortable being stared at by him for a long time.

"What do you think you can do for them now?" Moody didn't answer Harry's question, but asked rhetorically.

"Maybe I should help them." Harry replied.

"How do you want to help?" Moody asked, "Are you going to St. Mungo?" ”

Harry nodded.

"So do you think you're going to have a bigger role there than I do?" Moody continued.

Harry still knew the gap between himself and Moody, and he shook his head.

"So why do you think I stayed instead of going with them?" Moody didn't wait for Harry to answer, but said, "Because I have more important things to do here, and that's to keep Hogwarts safe." ”

Harry sighed, then nodded without speaking. He understands everything, but he just can't control himself. He was at an age when he was too calm and reckless, and it was torture for him to guard the rear at this time of tension on the front.

One of Professor McGonagall's secret assignments to Moody was to watch Harry and not let him run out to wave. After Harry and the four of them returned from their time trip that day, a guy who had been subjected to domestic violence secretly found Professor McGonagall alone and reported to her that something was wrong with Harry's thoughts, and that Harry now had the mentality that he wanted to die calmly. Taken aback, Professor McGonagall had to arrange for Moody to keep an eye on Harry, for fear that he would sneak into Diagon Alley one day to find Voldemort to fight him.

"Next, we'll arrange for the students to do their job of guarding Hogwarts." Moody told Harry that he had to find something to distract Harry from thinking about St. Mungo's side.

Moody now has the power to summon Harry, as he is now hired by Professor McGonagall to be in charge of Hogwarts security. In Zhang's words, Moody is now the head of the Hogwarts Security Section.

In addition to the need to fight on the front line himself, Moody, the head of the security section, also has the power to guide the Hogwarts students to defend the school.

Since Zhang Xu was in the light and Dumbledore was in the dark, the two of them joined forces to promote the establishment of the powerful organization "Hogwarts Defenders", and after years of development, it has become a well-organized and highly capable student organization.

From slaying the basilisk many years ago to eliminating the invading Death Eaters after the back-to-school dinner this year, the Hogwarts Defenders have shown a fighting prowess that cannot be ignored. The Auror Office has even stated below that students from this organization will be given priority if they sign up for the Aurors.

Now, under Dumbledore's deliberate management and Zhang Xu's covert concessions, this organization is deeply marked by Harry Potter.

When Dumbledore died and Professor McGonagall became Headmaster, she discovered that although the Harry Potter Leadership Program had been a success, she did not consider Harry to be a perfect leader. Because of his lack of coolness, the fire of hatred for Voldemort in his heart is likely to burn himself and even the entire team.

At first, Professor McGonagall wanted Zhang Xu to lead the students, after all, as a legend on campus, his influence was only matched by Harry. Even Ron, who once won the Goblet of Fire, lost to him at this point, because rumors in the rivers and lakes rumored that if Zhang had thrown his name into the Goblet of Fire instead of using the Goblet of Fire to barbecue, the champion of the Triwizard Tournament would definitely belong to him. And Zhang Xu has always been cautious enough, and there is no lack of foresight, at least there is no need to worry about him taking the students recklessly.

As a result, when Professor McGonagall communicated with Zhang Xu privately on this issue, the other party refused without hesitation, she couldn't pull down her hair and become a wheat meow to sell cuteness to ask Zhang for permission, I, Minerva McGonagall, also want to save face.

So Professor McGonagall could only negotiate with Bubbaji to let her stay in St. Mungore for more time, and then learn that Dumbledore used the position of acting professor of Muggle studies to tie Zhang Xu, so that Zhang Xu had to focus a considerable part of his energy on Hogwarts work, and then as an insurance to prevent Harry from going to waste.

The other insurance that Professor McGonagall had for Harry was Hermione. Professor McGonagall knew that Harry had always treated Hermione as a brother, and that she could listen to each other. Professor McGonagall gave Hermione and Harry, the highest of the two student positions, president of the male and female student council, respectively, so that the relatively calm Hermione could stop Harry if he was impulsive.

The last insurance that Professor McGonagall arranged was the creation of a new "Security Section", which would give the Security Section the authority to guide students, and the head of the Section would be Moody, who was experienced, strong, and able to contain Harry.

As for Lupin and Black, Professor McGonagall couldn't count on either of them. Blake, in particular, would be surprised if he didn't accompany Harry to the waves.

Harry, who was sitting in the security department's office at the moment, didn't know about Professor McGonagall's arrangements, but only worked with Moody to arrange a patrol work plan for the students who had no classes in the afternoon.
