The Ministry of Magic ordered Albus to be replaced by Dolores Jane Umbridge (Senior Inquisitor). Dumbledore becomes Headmaster of Hogwarts School of Witchcraft and Wizardry. The above regulations are in accordance with Education Order No. 28.

The notice spread throughout the school overnight, and everyone in the castle heard that Fudge and Umbridge tried all kinds of tricks to frame Dumbledore but to no avail, and finally coerced and lured the school board to get Dumbledore to leave. There was an atmosphere of panic on the campus, and it was felt that Dumbledore's departure had put the entire castle in a very dangerous state when a large number of Death Eaters had fled Azkabankaban.

For most of the previous half century, Hogwarts was known as the safest place in Britain not because of its powerful castle and ancient magic, but because Dumbledore, who was known as the first man in wizarding world, was the headmaster here. Now that the headmaster is gone, everyone has to admit that the castle suddenly seems less safe than it used to be.

But Umbridge didn't pay attention to this, she was already fascinated by the fact of becoming the Headmaster of Hogwarts, even if the Headmaster's Office was automatically closed, Umbridge, who couldn't pass through the stone monster, just fired a fire and shamelessly nailed a sign with the words "Headmaster's Office" at the door of her office, and then began to point fingers at the school.

For example, Umbridge formed an investigative task force and recruited many pro-Ministry students as members of the task force. These members are mainly members of the various pure-blood families of Slytherin.

Unfortunately, due to the previous revelation of Umbridge's background led by Ryan, these selected members do not look down on a half-blood witch from an obscure family. So the investigative team spent most of their time doing what they wanted to do with this skin, and couldn't spy on everything about the school for her as Umbridge imagined.

"By the way, what did you ask your sister to do. Hermione asked curiously in the library that day. "I heard that Rose Crystal went out for a few hours yesterday with a wooden box in the space bag, and came back with another big wooden box. ”

"Rose Crystal went to your dorm room to have a conversation with you again?" Ryan knew at once how Hermione knew about it, "it was the communication item I sent to Sirius and my shop, after all, that old woman has the Ministry of Magic behind her back, and the communication channels inside and outside the school are under her supervision. The Ministry of Magic has Floo Network administrators who keep an eye on every fire in Hogwarts except for Umbridge's office. At the same time, the investigative team, which is her lackey, will open all owl mail in and out of the castle. There is also Filch who keeps an eye on all the secret passages inside and outside the castle. ”

"In this case, we must have a secure communication channel to contact the outside world, especially if I do business, there are some contents that belong to trade secrets and need to contact the outside world. Once Umbridge's unscrupulous old woman sees these things, the hell knows if she'll sell them directly to my competitors. Ryan looked around and leaned closer to Hermione's ear as he saw no one approaching.

"The old woman. Hermione took a deep breath. "When she became a principal, she literally turned the school into a prison. ”

"What's going on?" Ryan asked, pointing behind Hermione. A Ravenclaw girl made it to the edge of a table with a book between them, but the other people at the table left, leaving only Zhang Qiu still sitting there.

"That girl is Marietta, the one who betrayed Harry and them. Hermione said in a disdainful tone, "People don't want to sit with her right now, and they don't want to talk to her. Only your compatriot Qiu Zhang is a really good person, and he is willing to approach her. ”

It's the equivalent of a social death, which is simply too tragic. Sure enough, whistleblowers are unwelcome in any world. However, this is also Marietta's own doing, if she was tortured or poured some potions and then confessed these things, it is understandable, but this kind of voluntary informant behavior is really unbearable.

"I must admit that Marietta did something wrong, but as a friend I can't leave her alone. At Saturday's book club event, Ms. Zhang explained to those who questioned her proximity to Marietta. Everyone in the reading club accepted this explanation, and compared with those who abandoned their friends when the situation was bad, people like Zhang Qiu were closer and more willing to get close. And everyone also knows that she is not the same as her friends, not the kind of person who will betray.

"Okay, we can get back to practice. After making sure that the members of the investigation team who had just come to check had left, Ryan beckoned everyone to continue practicing. Everyone immediately ran to the corner of the classroom, and then watched as Ryan waved his wand in the air, sending the tables and chairs flying into the air, and then slowly transforming into various obstacles distributed throughout the classroom.

That's what Ryan learned in his sophomore year at Castro Bruce Academy: use a lot of obstacles to set up a field in the classroom that is close to the actual battle, and then practice inside. For Ryan, who is now a high-level alchemist, it was easy to transform quickly or set some traps.

"Oh my God, why is this so difficult. Even the final exam that Professor Lupin made that year was not so complicated. Justin rubbed his arm and said that he had been in the field less than three minutes before he was hit by a shockwave trap.

"Legend has it that in the past, many pureblood families would have similar proving grounds for practicing magic and martial arts. Hannah explained quietly. "However, the family that still has such facilities today probably no longer exists. ”

"Yes, my grandmother told me about it before. Neville nodded. "But the cost of this kind of facility is not low, our family's training ground only has those obstacles, and this kind of alchemy trap can't be raised at all. ”

"We've never heard of anything like that. Weasley said in unison, and then Fred shrugged. "I guess my ancestor sold it a long time ago, but I think we should be able to rebuild it. ”

George nodded, then said to Ryan, "Hey, we'll be looking for you to order products when we rebuild the family training grounds." You must give us a discount!"

"Definitely. Also, now it's the two of you're going to get in, so don't be kicked out in less than five minutes this time. Ryan interrupted the twins' chat, and as they went down like this, Ryan was worried that he wouldn't be able to get everyone into the field three times by the end.

"Hermione, you don't tell me about your boyfriend, why those traps are so powerful when we go in. Last time, that sting spell made me feel like my right half of my ass and my left half of my ass were the same again. Fred said.

"That's because you're not serious, otherwise you can avoid that trap. IMHO, it's not a good thing for you to treat practice as something like a game. The real battlefield is full of blood and death, and you have to practice those life-saving skills until you are so proficient that you can subconsciously do them when you encounter danger. Otherwise, you may not be able to save your life in the event of a crisis. ”

"You're right. Fred didn't look like he was just smiling, he nodded solemnly. "Last time our dad told us that he was so undertrained that he was so lacking in combat that he would fall asleep on duty, and if it weren't for Ryan's bracelet, we might not have seen him. So he told us to be serious when we were fighting, and we did slack off before. ”

George nodded in agreement. "We've definitely been training hard today, so let's see, we'll keep going for a long time. With that, he and Fred rushed into the obstacle with a resolute face.

"Hopefully the training will make them stronger, so that some tragedies may not happen. Ryan thought as he listened to the sound of battle coming from the obstacles.
