Half an hour later.
All the shipgirls in the entire base gathered in the base, and there were even a few B.R.I.s listening in.
This would be the first time they truly interacted with another world.
Previously, due to only Lu Chen being on Earth, the Vanguard Fleet had actually not met anyone from another world besides Lu Chen.
Not to mention, a place with a unique worldview and supernatural entities like ghosts.
"So, I'll give a brief introduction to this world."
Lu Chen coughed.
He introduced the worldview of Demon Slayer in concise language.
It was nothing more than the story of how, during the Taisho era, an accident led to the creation of the progenitor of demons, Muzan Kibutsuji.
Then, he talked about the long entanglement with the Demon Slayer Corps.
He didn't go into too much detail about the specific plot, as the original plot would definitely collapse after he brought a bunch of shipgirls there.
Therefore, he mainly explained the technological level, the concept of demons, and the era they lived in to the shipgirls.
"The Taisho era...Speaking of which, doesn't the Heavy Cruiser fleet have a senior from that era?"
Taihou suddenly thought of someone.
"Mikasa...uh, in a sense, they are indeed from the same era."
Lu Chen felt that besides the sailing warships, Mikasa should be the oldest shipgirl in the Port Area.
It's a pity she wasn't in the Vanguard Fleet. Otherwise, it would be interesting to see what she thought about the "demons" that were everywhere in that era.
"Let's focus on the main topic."
Richelieu stood beside Lu Chen, signaling for everyone to quiet down.
"We have two goals for this expedition."
"First, complete two tasks: Eliminate the Twelve Kizuki and address the threat of 'demons' in that world."
"Second, Commander hopes to establish cooperative relations with that world."
"Is it like the same military alliance with the Port Area?"
Yukikaze raised her hand to ask.
"Of course not. Given their technological level, they're more suitable as our tributary state."
Lu Chen replied.
Although the "demons" had a strong presence in the Demon Slayer world, there was actually a Shogunate government.
With a unified administrative body, things would be easier.
Just like the Black Ships incident back then, as long as we show our strength in front of those so-called shoguns and emperors, they will obediently kneel down and become dogs.
"Oh..."
The shipgirls seemed to understand.
They were more concerned about specific issues, as diplomacy was usually handled by the Commander.
"What about the first task? Eliminating the Twelve Kizuki and the threat of 'demons'?"
"How should we do that?"
Essex asked directly.
"Uh..."
Lu Chen thought for a moment.
"Maybe just get rid of the demon king?"
Eliminating the threat of demons basically meant eliminating the demon leader, Muzan Kibutsuji.
All the demons in the world were created by him. Solving the source would take care of everything.
Besides, they had seen Muzan when they were in the Azur Lane world earlier.
But they didn't expect him to actually be the big boss of that world.
"Just him?"
The shipgirls recalled the middle-aged man with a somewhat gloomy expression.
"Doesn't he seem very powerful? At least he doesn't have the ability to travel across worlds like Commander?"
Richelieu thought about his enraged appearance and realized a simple truth.
"Otherwise, he would have crossed over to beat us up if he was that angry."
"..."
Lu Chen was speechless.
"You can understand it that way. From the perspective of other universes, he's not that strong."
He introduced the special abilities of demons.
Stronger physique than humans, afraid of sunlight, all sorts of bizarre Blood Demon Arts, etc.
For the Demon Slayer Corps, which consisted of ordinary humans, each Upper-Rank demon was very difficult to deal with, and killing them was very exhausting.
They often had to outsmart and outmaneuver the demons.
However, the shipgirls, who were warships personified, had a rather unique way of thinking.
They began to think about how to defeat demons using their own abilities:
"Muzan has five brains and seven hearts? We can only attack his weak points? Would it work if I use my main guns to bombard him? High-explosive shells or armor-piercing shells?"
Prinz Eugen was seriously considering what kind of ammunition she should carry.
"Demons seem to have no air defense capabilities at all. We can launch our carrier aircraft to carry out large-scale air strikes on their strongholds. If necessary, we can use thermobaric bombs and fuel-air explosives."
Essex was used to using the superior firepower of the White Eagle for area denial.
"Battleships and aircraft carriers can achieve integrated sea and air strikes. I will provide artillery support after the air strike is complete."
Richelieu nodded in agreement.
"We can also attack them underwater with torpedoes! They have no anti-submarine capabilities either!"
Taigei and Ikazuchi were eager to try it out.
Because the two worlds had completely different worldviews and power systems, the shipgirls' thinking was quite unique when facing the enemies of another world.
They were used to solving problems with familiar methods and tactics.
"..."
Lu Chen almost burst out laughing.
"Muzan Kibutsuji would kowtow if he knew you thought so highly of him."
"Just listen to my command then. Put away your white phosphorus rounds, napalm, and things like that! Don't accidentally injure the innocent natives."
"Also, Richelieu, Taihou, you two go to the naval base and bring some extra weapons, they'll be useful."
