"Hmm? Create the illusion of dismantling the ship?"

Grindelwald frowned, looking at Erina with a hint of confusion.

He didn't have much objection to the later request for long-distance transportation.

However, the first request Erina made earlier was somewhat puzzling to the first-generation Dark Lord. He would only agree to events involving large-scale manpower mobilization after determining their value.

"If it's just for confidentiality, I think the Obliviation Charm and the Confundus Charm are enough. I don't think it's necessary to invest too much manpower here—our manpower is tight, and wasting too much here..."

"The sky, conventional spells cannot block the prying eyes from above."

Erina looked up at the sky, her gaze extending upwards towards the boundless sky.

"As the most important shipyard in the former Soviet Union, there are at least three or more artificial satellites closely monitoring everything here above us. Although they only have the ability to take pictures for the time being, they can easily discover the progress of the construction period by comparing pictures taken over a continuous period of time."

Following Erina's gaze, Grindelwald subconsciously looked up, looking at the empty sky.

"Artificial satellites? What are those things..."

A trace of confusion appeared on Grindelwald's face, which touched his blind spot in knowledge again.

If he had vaguely heard of aircraft carriers, then he was completely unaware of the artificial satellite Erina mentioned for the first time—after all, the Soviet Union only launched the first artificial satellite in the human world on October 4, 1957, and at that time Gellert Grindelwald had already imprisoned himself in Nurmengard Castle.

"You can understand it as a kind of Muggle unmanned aerial vehicle, flying extremely high, far beyond the reach of most current attack methods... For more detailed information, I can help you find some books later, or find some experts in related fields to popularize it for you."

Erina glanced at the confused old Dark Lord, rubbed her eyebrows helplessly, and explained simply.

"In simple terms, in this era, unless the entire area like Hogwarts is in an unplottable state, or hidden with other large-scale spells, there is a risk of being discovered by Muggle reconnaissance satellites."

Without a doubt, as the only aircraft carrier assembly plant in the former Soviet Union, the Nikolayev Shipyard is definitely one of the key targets of the United States and even countries around the world with satellites. Erina would not naively think that the "eyes" on the dome would disappear as the Soviet Union disintegrated.

Unless they see with their own eyes that the *Ulyanovsk* aircraft carrier is dismantled into a pile of scrap steel, the Americans will never let go—if the Americans discover that it is not only not being decommissioned, but is being assembled and launched at an accelerated rate, and then suddenly disappears overnight, then the White House and the Pentagon will probably go crazy at the same time.

"I understand roughly, so you want to block the prying eyes from above?"

After pondering for a moment, Grindelwald temporarily did not delve into the principle of that "artificial satellite," stroking his chin thoughtfully and said, "I didn't expect that after so many years, Muggle technology has become more and more troublesome, let me think..."

"Anti-satellite reconnaissance? Impossible!"

Hearing the conversation between Erina and Grindelwald, Makarov had a look of disdain on his face, and finally couldn't help but speak.

"The area occupied by the No. 0 slipway is too large. Unless you find a way to actively shoot down the American satellites, there is no way to avoid the American's line of sight no matter what method you use—or, you can find a large enough lid to cover the entire shipyard, that would..."

"That makes sense, so let's just put a lid on it."

Erina nodded casually, turned her head to look at Grindelwald, and said in a solemn tone.

"This may be the largest and most far-reaching joint casting of Concealment Charms and Obliviation Charms in the history of the wizarding world—a project far more massive than the Ministry of Magic's modification of the Hogwarts Express and the construction of the railway and train station from London to Hogsmeade. A slight carelessness may trigger a new round of magical world secrecy clearing actions."

From 1827 to 1835, Ottaline Gambol became Minister for Magic.

In order to ensure that hundreds of students arrived safely at Hogwarts every year without attracting the attention of Muggles.

The then Minister for Magic, Ottaline, proposed a "bold and controversial" plan—to modify a Muggle steam train and use the train, a safe and comfortable means of transportation, to replace the original Portkeys and other unregulated ways of traveling.

And more than a hundred years later, in order to ensure that Hogwarts has high-end combat power to quell disputes when disputes arise between the magical world and the non-magical world in the future, as well as the "Wandering Hogwarts Project" in extreme cases, Erina followed the example of the former Minister for Magic and set her sights on the world's top means of transportation.

According to Erina's incomplete vision, even if the simply magically modified *Ulyanovsk* only has the three basic functions that are now mature in the wizarding world: flying, short-distance space jumps, and invisibility, it is enough to surpass the modern military warfare mode of the next few decades and play a decisive role in the situation.

Not to mention, compared with the common aircraft carrier-based aircraft carrier method, the magical world has more options to choose from, such as Fire Dragons, Thunderbird, Phoenix, Occamy, Thestrals... Even wizards carrying aerial bombs can temporarily serve as a miniature bomber.

If this once-in-a-lifetime opportunity is missed, wanting to build a nuclear-powered aircraft carrier of this scale from scratch, the difficulty and complexity are not as easy as directly grabbing an American Nimitz-class aircraft carrier.

"So, everything needs to be kept secret from Dumbledore?"

"At least before the *Ulyanovsk* appears on the surface of Hogwarts Lake, it is better not to worry Professor Dumbledore for the time being. The title of purchasing this big ship will also be the purchase of scrap steel, not directly buying the ship."

Grindelwald raised his eyebrows and glanced at Erina meaningfully.

Although he had long known that Erina was not a worry-free child, he did not expect that the girl solemnly and secretly asked her to bring her here today just to do such a big thing.

To achieve this, at least thirty or more wizards need to be dispatched for shift work just for concealment.

"Is it worth it?"

"The opportunity is only once. Apart from this big ship, the next time we want to get such a steel behemoth, we may only be able to rely on the spoils of war after the official start of the war—even if we can win, we won't have time to transform it."

Erina answered without hesitation.

Grindelwald nodded slightly, his eyes slid over the steel-forged island in front of him, and the corners of his mouth raised slightly.

"In that case, one last question... What are you going to do with these two Muggles? And for the follow-up assembly work, are you sure you have a way to convince those Muggle workers to wholeheartedly help you complete this big ship?"

"Of course, don't forget—what we have is not just cold money."

Erina nodded confidently and replied, with a hint of emotion flashing in her eyes.

The yet-to-happen history has told her what the most powerful bargaining chip is at this time. For politicians, it is money, and for ordinary people it is... survival.

"Then, Mr. Makarov, I look forward to seeing you next time. And..."

Erina smiled slightly at the two Soviet old men beside her, and then said softly without changing her smile.

"Sorry."

While saying this, the young Dark Lord turned around and walked towards the back, waving his hand casually.

"Help them reset this memory first, the time sequence is wrong... Let's go get that order first!"

Now is not the time to hesitate and hesitate. Once the news leaks out, it will not just involve her alone. The entire plan, Hogwarts, and even the magical world may be affected.

The scrap steel of the *Ulyanovsk* is not so easy to buy. Not to mention that the competitor she is facing is a guy who can raise the price wildly, even if there are no Americans to disrupt the situation, the aircraft carrier steel itself, known as "golden steel," is not cheap.

"Understood, Miss Deressa."

"Obliviate!"
