The Admiral of Hogwarts

"For now, we can only have Hagrid temporarily watch over his brother, hiding him in that forest. We might even have to temporarily tie up Hagrid's brother," Mr. Weasley said, walking over with two butterbeers at this moment.

"We can't use any magic, because the Ministry of Magic keeps records of magic use. A couple of times wouldn't be a big deal, but using magic intensively in one place will easily attract the Ministry's attention."

"If that's the problem, I think I can help," Hugo said, taking a sip of butterbeer after checking that no one was paying attention.

"At least our current level allows us to create a space covering a football field, where any magic used won't be sensed by the outside world."

"What, is that true?" Sirius exclaimed, eyes widening and becoming excited after hearing Hugo's words. "Can you really use magic in there without being discovered?"

"Don't worry, this is a secret magic I learned from your old family home," Hugo said with a smile. "As long as you don't let the magic escape the area, it won't be a problem."

"By the way, how do you create that space? Does one of you have to be on-site?" Mr. Weasley asked at this moment. As the current head of the Weasley family, with a natural talent for creation, he knew how troublesome these things could be.

"That's not necessary. For the largest version of the magic array, I only need to make 36 runestones in advance, and then you place them at fixed points according to my instructions. It's not difficult."

Hugo said with a smile. Unlike ordinary wizards, both Hugo and the ship girls admire the traditions of industrial society, so they naturally adopted the most popular modular design when designing this new type of magic array.

Because of the modular design, this magic array can naturally be broken down into many small blocks and assembled where needed, forming a magical barrier.

Compared to the traditional magical tools in the wizarding world, Hugo's new inventions, while temporarily unable to solve the inherent fragility of various moving parts, would undoubtedly require higher costs to achieve the level of similar magical tools.

However, whether it's convenient setup, simple disassembly, flexible use, or overall cost-effectiveness, they are superior to the old-fashioned magical tools.

"Does your thing only have concealment magic arrays? Are they all this large?" After Hugo introduced this set of magical tools, Mr. Weasley, as an old fighter of the Order of the Phoenix, immediately asked, because he realized the value of these magical tools in war.

"Of course not. For example, the set of magical tools I introduced to you before can be disassembled and used. Each runestone can support a 10 × 10 × 10 space," Hugo shook his head and said.

"But compared to disassembling and using them, these things can form a larger magical tool when aggregated together, covering a space much larger than the sum of the spaces created by individual parts."

"And in terms of the variety of these magic arrays, in addition to this magic array for hiding magical fluctuations, we also have an invisibility magic array and a defensive magic array."

"Thank you, we will purchase these things from the Mutual Aid Society when the time comes," Mr. Weasley said, raising his glass at this moment. "The hot butterbeer is good today, perfect for having a little more."

Obviously, Hugo's previous secret plan worked surprisingly well. Although it was unclear whether Dumbledore had seen through anything, at least most of the members of the Order of the Phoenix had not seen where the true command core of these ship girls was.

This is why Mr. Weasley changed the subject, because in his opinion, Hugo and the others were at most apprentices of the Mutual Aid Society, so the topic was not suitable for discussing too deeply.

After finishing a glass of butterbeer, Hugo and the other two left the Three Broomsticks Pub together. After all, Sirius and the others looked like they had things to do, and it wasn't appropriate for them to stay there.

"Where are Harry and the others going?" Just as they were heading to the restaurant where Xuefeng and the others were, Hermione unexpectedly saw Harry, Ron, and Ginny ahead of them, also walking on that path.

"They should be going to the Hog's Head Pub. After all, there are only two shops on this road," Hugo said, glancing at the direction Hermione was looking.

"I really hope Harry and the others remember to bring their own cups. Luna told me that their head of house, Flitwick, said it's actually quite safe there, the only problem is the hygiene is a bit concerning."

"It seems Harry has decided to form his study group. But honestly, information leaks from the Hog's Head Pub like a sieve. I guarantee Umbridge will know what they're doing before Harry and the others return to the castle," Venetto said.

"Trust Harry and the others. At least, I don't think Harry and the others will get into trouble so easily," Hugo smiled, then followed Venetto and the others into the restaurant.

As soon as they entered the restaurant, they went to the private room that was never open to the public, as usual, and listened to Xuefeng's report on the recent situation while eating.

"—Currently, the number of transport ships capable of hyperspace jumps has reached six, and four more will be put into use within the next two weeks," Xuefeng opened a holographic projection and began to report on the ship girls' recent activities.

"The Mars base is now being built according to our plan. Mars Base One has found sufficient water sources and has begun to cultivate various algae and magical plants."

"According to the plan, by Christmas, the Mars base will be able to meet the self-sufficiency needs of Mars and various bases in Mars orbit for necessities such as oxygen, water, and food."

"This is very good news," Hugo nodded. "By the way, I remember that the largest space dock in our plan will be built in Mars orbit. What is the progress of the project now?"

"The core parts are being assembled. To this end, we have mobilized most of the production capacity we have," Xuefeng said, flipping the data back two pages. "But even the first phase of the project will not be completed until May next year."

"This is mainly because our core task now is to build the Mars base and a series of industrial facilities on Mars, so the construction of ships can only rely on the shipyard in lunar orbit in the short term."

"I understand, this is the principle of sharpening the knife does not delay the work," Hugo smiled. He knew that the current construction project plan was scientifically planned by the ship girls, so he would not interfere.

Just like the report just now, the first batch of Mars bases has a total of seven. In addition to the three bases located on the surface of Mars, it also includes an unmanned armed outpost on Phobos and three space stations.

According to the plan, the first phase of construction is mainly to solve the problem of permanent survival of personnel on Mars and to establish most of the supporting industrial facilities required for the future Mars shipyard.

And when all those constructions are completed, their planned true space colonization work can begin, and this will be the first step for humans to become a spacefaring race.
