To initiate war between worlds and completely conquer the other side.
Lu Chen's understanding of this power was to overturn the target world, defeat all of its inhabitants, and then claim everything they had.
Wars between countries on Earth were simply too weak.
This was a true "World War".
And a World War where everyone would participate, from ordinary people to demon gods.
The victor of the war would gain the highest administrative authority of the world, as well as all technology and powers.
It sounded like the rewards were incredibly generous, with the winner taking all.
Defeating a demon god would grant you the power of that demon god.
Of course, choosing who to declare war against was a skill.
Picking on a weak world wouldn't be worth it, as they wouldn't have much to offer, making the war's gains and losses disproportionate.
Challenging a world that was too strong would easily get you slapped to death by some unspeakable monster.
The teleportation portal was two-way! It would be hilarious if your own home was conquered first.
Lu Chen glanced at his few neighbors.
Forget it.
The Demon Slayer world had already been conquered, no need to waste time.
Hong Kong was already an ally.
The Type-Moon, Date A Live, and Honkai Impact worlds were all difficult to deal with, and they each had quite a few wives.
Peaceful development was better.
He would find a suitable target later.
With that thought, he turned on his communications device.
"Everyone, assemble! There's something new we need to do!!!"
……
Half an hour later.
Dozens of ship girls gathered in the conference room.
"Commander, are we going on another adventure to another world?"
"Can I come this time?"
Yukikaze was eager to go.
"Uh…"
"It's kind of like that, but I have some other tasks to assign."
Lu Chen presented three mission objectives.
"Launch a satellite, build a spaceship, and master a power from another world."
"How long will it take for the first two?"
The ship girls looked at Myoko, the one in charge of research.
"Launching a satellite isn't difficult. We have both Azur Lane and Gundam technology, so it'll be easy to send a satellite into Earth's orbit meow."
"But building a spaceship that can travel between planetary systems might take some time."
Myoko pondered for a moment, resting her chin on the table.
While ship girls hadn't previously researched space technology, the Gundam world tech tree given by Lu Chen didn't just contain various Gundam models.
It also included space warships like the Angel, the Izumo, and the Minerva.
They were both carriers for Gundams and starships capable of fighting in space.
Once they understood the technical principles, they could either create an exact replica or manufacture a similar one.
"Oh, if we can build spaceships, then we can also modify our ship outfits…"
Kaga's eyes lit up.
"That's right."
Lu Chen nodded.
"We can use starship manufacturing technology to turn you into space carriers, space battleships, space cruisers…"
"!!!"
Several aircraft carrier and battleship ship girls were immediately excited.
They were used to seeing destroyers flying around with rocket backpacks in the sky, and now they had the opportunity to break through the atmosphere and head to space.
"Myoko, my future rests on you…"
"I'll explore the stars with the Commander in the future, achieving a harmonious love in a sea of stars…"
Taihou cuddled Myoko's head and rubbed it fiercely.
"I'm going to suffocate!!!"
The beast-eared ship girl managed to push her head up from the mountain of hair.
Lu Chen couldn't help but stare.
"What about the third mission?"
"Obtain a power from outside this world? Commander, do you have any leads?"
Richelieu rolled her eyes at Taihou and asked.
"Well… it's literally what it says, we have a lot of neighbors around."
Lu Chen projected the hyperdimensional star chart.
"We currently have Azur Lane and Gundam technology. We just need to acquire another type of technology, whether it be magic or something else."
"Looking at our neighbors, there are those who use Honkai energy, Type-Moon magic, and Date A Live spirits."
"They each have their own systems, we can try to get one."
Over a dozen heads leaned towards the star chart to inspect it.
"So Commander, which world are you going to?"
"Hmm…"
Lu Chen looked at the map.
There was still a world mission hanging over the Date A Live world.
[Resolve the Threat of the Origin Spirits]
It felt like something that couldn't be solved, he had no idea how to approach it.
Shido Itsuka was just too tricky.
"Honkai… Honkai energy seems interesting, but it can cause Honkai Beasts."
"The stronger a civilization, the stronger the Honkai Beast. What kind of Honkai Beast would appear here?…"
After some thought, he turned his attention to Type-Moon.
[Fate/Grand Order]
This wasn't just a single world with F/A, F/SN, or F/Zero. The Type-Moon universe already had a bunch of singularity and alien worlds.
[External Communications]
Static—
The screen was covered in snow.
[Communications Established: Star Sea Alliance - Chaldea]
"Hello? Hello? Is Gudako there?!"
"Let's save humanity together!!!"
