After obtaining immeasurable resources from another world.
The development speed of the residence has seen a visible increase.
Not only have some of the Shipgirls started to undergo hull modifications, replacing them with more advanced energy weapons.
The Mind Cubes that were once shelved due to insufficient resources have also begun to be put into production.
A few days later.
Port shipyard.
Lu Chen, with a few accompanying Shipgirls and the repair girl Akashi, stood beside the shipyard.
Docked in the shipyard below were ten identical, unarmed, approximately 100-meter-long transport ships.
All are general-purpose Bri hull.
Akashi took out a box and carefully opened it.
Inside were ten neatly arranged light blue Mind Cubes.
"Commander, these are the first batch of Mind Cubes manufactured. Using them can give warships self-awareness and transform them into Shipgirls, nya."
"Be careful, don't swallow the Mind Cube again."
Lu Chen took the box.
He could feel the powerful force contained within the Mind Cube.
The construction of this thing is completely a black box technology, even Akashi can't accurately distinguish its internal structure, she can only manufacture it according to the existing production process.
As for the principle of the Mind Cube, how it interacts with the human body or warships, it is a complete mystery.
"Can the Mind Cube be used for Gundams? Build a mecha girl?"
"Besides the Strike Freedom, aren't the Unicorn, Barbatos, and the others still empty?..."
He suddenly had a brainstorm.
"..."
"Theoretically it's possible, but I think from a combat effectiveness standpoint, mecha girls should be inferior to Shipgirls, nya."
Akashi scratched her ear and thought for a moment.
"And the Gundam is designed according to ordinary models... If you want to build mecha girls, you should redesign the internal layout..."
"Alright, I'll summon a few Bris first."
Lu Chen raised the Mind Cube above his head with one hand, focusing his consciousness on the few ships in front of him.
He could feel his consciousness connecting with the Mind Cube in an instant, pouring into the hull not far away.
Swish-
The Mind Cube in his hand, along with the hull, turned into a ball of light, then gradually twisted and deformed in the air.
A few minutes later.
A small Shipgirl with white short hair and a short skirt landed on the sea.
She was holding a large wrench about the size of a person, and her tail was like a charging plug.
Opening her eyes, she saw Lu Chen and immediately pounced on him.
"Buli! Commander, I can buli your fleet!"
Although it was their first meeting, Bri was very enthusiastic, directly hugging Lu Chen and rubbing against him.
Buzz-
Lu Chen followed suit and summoned the other Bris in one go.
Ten Purple Bris stood side by side in front of him, like clones. Except for the numbers on their chest plates, their clothes, equipment, and even the tufts of hair on their heads were exactly the same.
"Wow."
Everyone was a little curious about these newly born modified girls.
"Commander, it seems that your adaptability to the Mind Cube is really strong. When we summoned Bri, the process was much more complicated than this."
Kotetsu and the others looked at it with wonder.
"Why are there only so many Mind Cubes?"
Lu Chen was still a little unsatisfied.
"Didn't I tell you, make 6000 Bris? How is 10 enough?"
"Meow meow meow?!"
Akashi jumped up in protest.
"Commander, the manufacturing process of Mind Cubes is very complex. You want me to make 6000 Mind Cubes?! This is exploiting Shipgirls, nya!!!"
"It's already a miracle that you can make ten first?! The rest... will probably take a year, no, two and a half years!!"
"That's too long..."
Lu Chen thought for a moment and looked at the Bris he had just summoned.
"Can you build Mind Cubes?"
"Buli?"
Bri tilted her head and thought for a moment.
"Not yet, but if others can, Bri should be able to learn!"
"Very good, Akashi, you'll teach Bri how to make Mind Cubes from now on."
Lu Chen patted the proprietress.
"Then let Bri summon Bri, and then let the newly born Bri learn how to make Mind Cubes from the previously summoned Bri, summoning more Bris."
"???"
Akashi and the other Shipgirls were directly stunned.
"Commander, are you speaking in tongues?!"
"No, no, you need to change your way of thinking."
Lu Chen answered.
"Think about it, if 10 Bris can manufacture 10 Mind Cubes in 5 days, they can summon 10 more Bris."
"Then a total of 20 Bris will rub together Mind Cubes. In another 5 days, it will become 40 Bris..."
"40 Bris rubbing together Mind Cubes, then 80, 160, 320... Anyway, our resources are enough, we can make as many Bris as we want."
"Excess Bris can also be sent out to develop resources on Earth and in the Demon Slayer world, using the developed resources to build more Bris, achieving a virtuous cycle."
"According to optimistic estimates, without affecting other construction work, let alone 6000, we are expected to manufacture one million Bris within half a year."
"Of course, if it's feasible, we can also try using Mind Cubes to manufacture new Shipgirls or mecha girls..."
"!!"
The Shipgirls usually stay in the port area, with a peaceful and indifferent appearance, where have they experienced such a large-scale activity.
One million Bris!
The total population of the port area, including the little yellow chickens, is less than 10,000.
"What's wrong with this, Earth is so big, even one million people is just barely filling a city."
"Bris, these super workers who can repair, mine, and manufacture weapons, and are so cute, the more the better."
Lu Chen didn't think much of it.
"..."
Such a shocking plan directly shocked everyone, making it difficult for them to recover for a while.
"This is... a chain reaction?"
Belfast suddenly felt that this exponential growth situation was strangely familiar.
"Commander, are you going to do controlled Bri fusion?!"
...
(The picture is a mecha girl running by AI, how about some mecha girls in the future?...)
