On 3 May, Dumbledore finally made the decision to prepare a general attack on the Ministry of Magic in London. For the worst-case scenario, Ryan secretly deployed the floating fortress above the Black Lake in advance, and at the same time unloaded a large number of goods in the Black Lake under the cover of night and the floating fortress. Then, on the night of May 2, he and Hermione rushed to Hogsmeade.

The next morning, they woke up early to prepare, and after breakfast, they rushed to the conference room on the ground floor of the Ministry of Magic, which was Hogsmeade's temporary command center, where Lupin and Sirius were already waiting for them.

"You're here so early, let's just pack up and rush over, nothing else. I didn't expect it to be later than you. Ryan said after hanging his coat on a nearby hanger. Today, he and Hermione were both fully armed, each wearing a suit of light armor that had been treated with very complex enchantments and alchemy.

"We didn't go home last night. Sirius smiled and said, "We've stayed here all night, and then we've slept in this conference room on the mattress we've conjured, and we're worried that something might happen." ”

"It's been a lot of work. Ryan asked with a soft sigh. "By the way, Sirius, didn't you say you were going to take part in the final blow against the Ministry of Magic in London? ”

"I wanted to pass. Sirius shrugged helplessly. "But Professor Dumbledore has asked me to stay, as he took almost all of the Ministry of Magic and the Order of the Phoenix with him during today's general attack, and I have been assigned to stay behind to strengthen the overall defense of Hogsmeade in order to prevent us from being attacked. ”

"Mr. Headmaster is still a little worried!" Ryan thought, but it also made sense, after all, his guerrillas and the new werewolves led by Lupin did not highlight some of their members because they had always valued the ability to fight in groups. In this way, in the eyes of ordinary people, they will feel that Ryan lacks top-notch combat power except for a few people.

Therefore, Professor Dumbledore still drew valuable combat power and sent Hogsmeade when such an important battle broke out, to ensure that his rear would not be threatened by the enemy.

"It's better for you to stay, Hogsmeade really lacks a person who can lead everyone to launch a counterattack, and Professor Lupin's subordinates and I have been training too short to cultivate a real elite like you for the time being. Ryan said as he took out a small box from his space bag, which opened to a thin black jumpsuit.

"In order to make up for the lack of combat effectiveness, I specially prepared some special props, but unfortunately the shelf life of this kind of thing is only about half a month, and it is also very difficult to produce, so I can only concentrate on using it at this time. Ryan unfolded his jumpsuit and said, "I had the Weasley twins deliver the hazmat suits for London last night. ”

"What's the use of something that looks like a Muggle diving suit?" Sirius, who had studied Muggle culture seriously for a while when he was younger, took over the coveralls and asked curiously. "Does it provide the same magical protection as your protective bracelet?"

"Yes, but it's more effective than you think. Ryan smiled, then said the best feature of this tight hazmat suit. "This garment is capable of resisting a requisite spell. ”

This is something that Ryan and the others have only made after returning from Silvermoon City, and although this hazmat suit is very thin, it actually has a mezzanine. Inside the mezzanine is an alchemistically treated ooze monster.

When they were in Silvermoon City, they discovered that the Ooze Monsters had about the same health as humans, and that they could be shaped as easily as liquids. Inspired by this special armor, Ryan discovered that the Ooze Monster had been tucked into the compartment of the suit after treatment, and he was able to block the user's attack with a Death Curse as he expected.

It's just that because the ooze monster can only play a protective role when it is alive, even if the alchemy potion is used to keep the ooze monster dormant to maintain its life as much as possible, the lifespan of the protective suit is only half a month. Coupled with the rarity of raw materials, Ryan has only now scraped together enough protective clothing to fight a war.

"It's a miracle!" Sirius said in surprise as he looked at the suit. He didn't question why Ryan hadn't come up with this thing before, in his opinion, it was enough for this kind of thing to be mass-produced on a small scale.

"If it's a miracle, I have 150 more miracles here. Ryan finished pouring out a small pile of hazmat suits from his space pocket, "Now hurry up and send them to each and every combatant, because I've always felt a little uneasy about the situation this morning." ”

"You're right," Lupin nodded. "In five minutes, Professor Dumbledore will leave Hogwarts for London, and the rest of the day will be the lowest level of defense between Hogsmeade and Hogwarts, so it's not wrong to be vigilant. ”

After saying that, Lupin called a wolf in from outside the door and asked him to go outside to distribute the suits, while he and Sirius ran to the next door to change into the suits.

"It's pretty good when you put it on, and it's easy to fight. Lupin and Sirius changed their clothes and walked out of the next room, and as soon as they entered, Sirius pulled out his wand and made a few gestures before commenting. "It's just a little stuffy. Sirius had just finished speaking when an oil lamp in the room lit up.

"Professor Dumbledore has left Hogwarts. Professor Lupin said after the lights came on. "If all goes well, the general assault on the London Ministry of Magic will begin in five minutes. ”

"Now let's get into the battle position. Ryan said, "Raise the whole of Hogsmeade to the highest alert, and I think Mysterio and his elite men could appear near Hogsmeade at any moment." ”

"You're right, we really need to act now. Everyone present nodded, then put on the hat of the hazmat suit and pulled on the mask, and finally put on the hood and walked out of the room.

Several guerrillas and werewolves who had been sitting on a bench at the door of the conference room had stood up when they had come out, and followed them towards the door. Along the way, all the wizards who stayed at the Ministry of Magic saw this group and drew their wands and pointed them to their chests and bowed to Ryan and them.

"Commander, there is a sudden surge of unidentified magical reactions around you. "Just as Ryan and the others returned to the surface, a guerrilla under Ryan's command contacted Ryan through the alchemy props he had sent earlier.

"What's the specifics?" asked Ryan, holding a magical metal plaque as he walked. "How many enemies are there? ”

But the next answer stopped Ryan and the others, as the response from the communicator was, "I don't know how many enemies there are, but now the display crystals you gave us are marked with enemies everywhere, and there are at least 3,500 of them." ”

"It's all over the place!" "3500!" everyone's faces turned ugly all at once, especially Ryan. Because he knew that he had prepared a large number of heart trees and reconnaissance methods from multiple worlds around Hogsmeade and Hogwarts for safety. The detectors that had been sent to the guerrillas were connected to the reconnaissance points.

Voldemort probably had his own way of avoiding the detection magic of this world, but in the face of the mixed detection methods of multiple worlds, even the strongest Dark Lord in decades could not avoid them all, which is why Ryan was able to detect that the situation was not right.

"How much time do you have left to get here?" he asked, holding the metal plaque up in front of him.

"Ten minutes at most, we can see them on the outskirts of the woods. The partisan said quickly.
