37 Alien Invasion

Although an earthquake occurred, neither of them panicked.

They even felt like discussing the situation.

"It's a strong earthquake, accompanied by a rumbling sound. It seems like another disaster has occurred."

Yumemi Okazaki remarked while looking at the earthquake graph on the screen with Roy.

"A powerful monster has arrived?"

"A monster capable of causing such intense earthquakes is truly remarkable." Yumemi Okazaki said while looking at the location of the epicenter of the earthquake using her satellite.

"It may not necessarily be a monster."

Earthquakes.

The fundamental cause of this natural phenomenon is mostly due to plate tectonics. Therefore, earthquakes are quite frequent in locations where plates converge, with Japan being the most typical example.

However, earthquakes, fundamentally, are vibrations caused by the rapid release of energy in the Earth's crust.

In other words, only forces capable of shaking the earth can trigger earthquakes.

Based on this theory, developing a so-called crustal vibrator is feasible.

It has been mentioned before. Due to various reasons, the people of this world have now gathered on a supercontinent. And this supercontinent itself rests on a tectonic plate. It's somewhat similar to the African continent, so earthquakes don't usually occur here.

For this reason, when a seismic sensation occurs, it's probably because a monster is using its powers nearby.

Of course, since it's not the supercontinent itself releasing energy, no matter how powerful the monster's strength is, the seismic power it causes is limited.

If the entire supercontinent were to experience a severe earthquake magnitude 6 or higher on the richter scale, then its strength would probably be at least Dragon-level.

Yumemi Okazaki tapped on the keyboard.

"It's A City... Hmm... Is this an alien invasion of Earth?"

From the satellite images, a massive ship was seen hovering over A City.

It was a battleship rivaling the size of half of A City.

"So that's what's happening."

Roy pondered.

"You seem to know something."

"It's probably the so-called cosmic overlord Boros coming to Earth."

"Huh, how do you know?"

"Have you watched any anime or manga?"

"I see what you're getting at." Yumemi Okazaki nodded in understanding. "Are you saying you've seen a work set in this world?"

Roy nodded.

"But I don't remember much, but I probably know some things."

"Who's the protagonist of this world?"

"Saitama? Speaking of which, Yumemi, I've also seen works that include you."

"Really?"

Yumemi Okazaki didn't seem very concerned about this and didn't express any desire to continue discussing it.

Her overly indifferent attitude made Roy curious, and he asked, "Is this your only reaction?"

Yumemi Okazaki chuckled and said, "Do I need to react differently? Roy, are you trying to see me surprised? You're such a mischievous guy."

"Generally speaking, upon hearing such news, most people wouldn't believe it, or even resist believing it... although I've never said that to anyone else."

"What are other people's reactions like doesn't interest me much. Maybe it really is as you said. If you're interested, why not conduct an experiment like that?"

"Forget it."

"To be honest, I believe what you said. Because I've had similar experiences."

"You mean, you've been to a world depicted in a work you've seen?"

"Yes. So at that time, I was also thinking, could my experiences also be portrayed as a story in some work... I didn't expect it to actually happen, but it doesn't seem like there's anything to be upset about. After all, if this is an objective fact, then it can only be explained." Yumemi Okazaki leaned in and asked earnestly, "Let me ask something, in that work, am I the protagonist?"

"No."

"Oh, what a disappointment."

Roy looked at Yumemi Okazaki and said, "Yumemi, you're really broad-minded."

"Am I? Not necessarily. My experiences being portrayed as a story by a person or a group of people is not seamless. So equating a work with a particular world is an arrogant idea." Yumemi Okazaki said seriously, "It's a simple truth. When you watched that so-called anime or manga that included me, did it elaborate on my 'magic' theory?"

"Not really."

Yumemi Okazaki hails from a world where the Unified Theory has been completed, unifying the four fundamental forces... strong force, weak force, gravity, and electromagnetism... in the universe.

And Yumemi Okazaki, the youngest doctor.

She proposed the existence of another force besides the four fundamental forces, which she called magic.

To prove this magic, Yumemi Okazaki piloted the Probability Space Hypervessel and traveled to another world.

Yumemi Okazaki calmly stated, "But now you know, right?"

Yes, Roy now knew about the Unified Theory.

The basic science from Yumemi Okazaki's world was far more advanced than the 21st century where Roy lived. Naturally, the overall technological level in her world was much higher than Roy's world, at least fifty years ahead, or even a hundred years.

Just the Probability Space Hypervessel, a black technology capable of traversing dimensions, probably couldn't be developed within a couple of hundred years.

Roy met Yumemi Okazaki.

Incidentally, Yumemi Okazaki became Roy's mentor and helped him catch up on his studies.

At first, he couldn't learn, but after some brain development, he quickly grasped it. Because of this, Roy was able to create black technology products like artificial intelligence and nano battle suits.

Yumemi Okazaki said, "That's how it is. Ultimately, I wouldn't think my life is arranged by some writer, painter, or screenwriter as fake and meaningless just because someone tells me that my world is actually from an anime, manga, or light novel."

"Even if I were to tell you about your setting?"

Yumemi Okazaki shrugged and said, "Then you've read my biography. People like me will be known a hundred years later. Even if I don't write an autobiography, there will probably be plenty of friends willing to write one for me. And even if it's a setting, there are some things that aren't written, right? Like my parents. Are they mentioned in the setting?"

"No, they're not."

"So, can you say my parents don't exist?" After Yumemi Okazaki finished speaking, she looked thoughtful. "Come to think of it, I can't completely deny that I haven't been influenced by this thing. Maybe subconsciously, I still have some aversion to it."

"Why would you say that?"

"Because, this is actually a phenomenon worth exploring and studying, isn't it? Existence is rational, existence is knowable, existence is science. If we can clarify the connection between 'work' and 'reality,' then it may be another profound achievement that could profoundly change human society and civilization."

Yumemi Okazaki suddenly became excited.

Roy chuckled and said, "Do you want to create the Storybook Shoes?"

"Aren't you trying to create Full Metal?" Yumemi Okazaki retorted. "We're both the same. But about Storybook Shoes... maybe this gadget can only be created after exploring the connection between the work and reality... No, wait, does the world of Doraemon really exist?"

"Maybe it does, maybe it doesn't. Who knows."

"If one day I could reach that world, that would be great. There must be a lot of knowledge waiting for me to explore, which would excite me."

"Don't forget about me then."

"Naturally."

The two smiled at each other. Roy looked at the computer screen, the massive object displayed there, and said, "But getting back to the point, compared to gadget far away, the super battleship of the cosmic overlord here is more exciting and more real."

Yumemi Okazaki looked at Roy. "Are you tempted?"

"Definitely. Rather, only someone with a little brain, even many researchers, would consider that spaceship extremely valuable. It's not just a spaceship, it's a new era."

"Indeed."

The two agreed and prepared to set off.

Rational thinking.

This was definitely not some friendly aliens coming. The battleship directly broke through the atmosphere and descended only a few kilometers above the ground.

And then it fired a full barrage, destroying A City, the largest city on this supercontinent, in an instant.

This was a declaration of war.

Non-combatants should urgently evacuate.

Yumemi Okazaki asked, "How should we go?"

Roy replied, "By car."

They went to the garage, where there was an off-road vehicle. It wasn't important when he made it, so there was no need to investigate further.

"It's not too far from here to A City, we can arrive quickly."

"Do we need to rush?"

"Well... it's always better to be a little faster. Otherwise, when we arrive, the event might already be over."

"I don't think your sister has that kind of power. Hmm, you're not talking about Tatsumaki but about Saitama, right? Hehe, if it's him, there really is a possibility."

They chatted as they set off.

A City.

Even from the outskirts, they could see the massive battleship that covered the sky.

Sitting in the driver's seat of the high-performance off-road vehicle, wearing sunglasses, Roy looked over there and said, "It's quite oppressive."

"After all, it's really big. It's the first time I've seen such a large spaceship."

Yumemi Okazaki, sitting in the passenger seat, also felt quite shocked.

"Judging by the size of this starship, it should be about 15 kilometers long and 4 kilometers wide. It's exaggerated. Supporting the navigation and levitation of this starship, the power source must have amazing energy and technology. Roy, forget the rest, we must get hold of the power system."

"Yes." Roy also thought so. He said, "Boros, the leader of the Dark Matter Thieves, has amazing physical qualities and regeneration abilities because his race has adapted to extremely harsh planetary environments. Boros is even more outstanding among his race. His combat power is above Dragon-level. Under normal circumstances, he has the power to turn the Earth upside down within ten days."

"That sounds terrifying. I'm definitely no match for him, so I'm not going." Yumemi Okazaki said, "I'm not a combatant anyway, I'm not suitable for the battlefield."

"But aren't you the boss?"

"Boss... Oh, I see. So, Reimu is the protagonist? But that time was just a little skirmish, in the end, it was a happy ending for everyone, wasn't it?"

Clearly, they had prepared to sacrifice themselves along with the Earth-destroying bomb, if not for being stopped by their own assistant.

Or something like that?

Can't quite remember.

Compared to believing in the works he had seen, using the settings and plots of those works to understand the world he was in, Roy tended to lean more towards gathering new information for understanding. The original works could only be considered as a kind of guide, not classics.

Seeing Roy's skeptical expression, Yumemi Okazaki raised an eyebrow and said, "I'm just a university professor who specializes in theoretical physics. I have nothing to do with combat, and I'm completely powerless. Do I look like a warrior to you? Anyway, I'll be waiting for you here."

"All right then."

Roy didn't insist.

"Take care." Yumemi Okazaki waved to Roy.

By the way, Yumemi Okazaki didn't want to go simply because she didn't want to break a sweat, right? After all, if there was a fight, it would inevitably involve vigorous activity. Yumemi Okazaki was essentially human, even though 2D anime girls don't sweat, but the problem is, Yumemi Okazaki is not a flat character now.

Ahem, no need to dwell on it.

They stepped out of the car.

Roy quickly suited up in his nano battle suit.

He shot straight into the sky, flying towards the direction of the battleship.

"No entrance? It doesn't matter, just break in directly."

The nanomachines quickly reconfigured behind him into four high-energy beam cannons. As long as they could hit, even just one shot could send a demon-level monster to hell.

Considering it was a battleship capable of interstellar travel.

Roy bombarded with the four cannons concentrated.

Hum...

Encountering no obstacles, it was like ice approaching flames, the battleship's armor quickly melted, soon creating a large hole large enough for several people to enter and exit simultaneously, emitting hot molten steel.

"Wow, is this armor one or two meters thick? It should still be the outermost armor."

After a sigh, Roy rushed into the spaceship.

It seemed like there were professional heroes fighting monsters below, but Roy probably didn't need to intervene too much.

From the data obtained from the scan, they all seemed to be S-Class heroes, each stronger than the next. The dignity of such powerful individuals is generally very high. If an unknown person rashly goes to help, they might be seen as looking down on them. So, it's better to pretend not to see and go directly into the enemy's crystal.

Hovering in mid-air, Tatsumaki emitting green light squinted his eyes.

"Is that... Roy just now?"

Entering the interior of the battleship.

They were still on the outermost perimeter.

"So, the places to go are the engine room and the control room."

The heart and the brain, these are the two most important organs of the human body.

The engine room is equivalent to the heart of a battleship, and the control room is the brain of a battleship. These two places are the most valuable positions of this battleship in terms of value and technological content.

"As for the design and construction of this ship, I'll leave it to you to collect the information."

Two of the four high-energy beam cannons floating behind Roy quickly decomposed and reconfigured into multiple spherical shapes, flying out from the gap.

"Very good, there's no material with strong isolation against scanning. But for such a large-scale battleship, it should take quite some time to work, so let's take advantage of this gap and dismantle the power system of this ship."

As for the computer in the control room.

Oh right, and the ammunition and weapons in the arsenal, but no rush.

Boom!!!

The hull shook violently, and there was a high-energy reaction above the battleship.

Roy looked up, as if penetrating countless obstacles, saw what was happening there, and muttered to himself, "Has Saitama arrived inside the battleship long before me? He even fought the leader of this battleship... Well, it doesn't matter, I have no intention of fighting that Boros."
