Half an hour later, having sated their lust, the three washed their bodies once more.
Then, after dressing themselves, they lay lazily upon the bed.
Shuang Uchiha closed her eyes, clinging to Rasa's warm chest like a submissive kitten, already deep in a peaceful slumber.
Her breathing was steady and long, as if she were drifting through a beautiful dream.
Ziyou lay on the other side, her arm awkwardly wrapping around Rasa's own, her eyes slowly drifting shut as well.
Rasa lay in the center, staring at the ceiling as his thoughts drifted like aimless clouds.
After a dozen minutes of cozy, wordless silence.
Rasa finally spoke:
"Ziyou, can your lifespan be shared with others through the contract?"
Hearing this, Ziyou opened her eyes slowly and shook her head, her voice soft and airy.
"Rasa, this concubine can only sign such a bond with one person. It is ineffective for any more."
Her gaze held a trace of helplessness and regret, as if she were lamenting her own limitations.
Having just had her virginity claimed by Rasa, the traditionally minded Ziyou had already placed her entire heart upon him.
She had even dropped the "Lord" title, addressing him by name.
"I see. That's quite a pity."
Rasa nodded with a hint of disappointment.
Though he had gained a lifespan of thousands of years, human greed was boundless.
Now that Rasa could live that long, he naturally wanted his other women to share that eternity with him.
But since Ziyou had spoken, there was nothing to be done for now.
As for the items in his system.
Up until this point, he hadn't found anything related to extending one's natural lifespan.
Suddenly, Rasa thought of something, and his eyes lit up.
"Do you have any others of your kind here?"
Ziyou's eyes also sparked with a bit of excitement.
"Though this concubine has no kin in this land..."
"I am capable of assimilating ordinary jellyfish, cultivating their intelligence until they become true Summoning Beasts."
"Since my Sage Land is complete, it is time I began expanding my own following."
As for going back to her home sea to find her kin?
Ziyou would never do such a thing.
Her reputation back there was already established.
The image of her having mediocre strength was fixed in the eyes of her peers.
To change their minds.
She would have to spend a great deal of effort beating them into submission, and even then, they might only obey on the surface.
Rather than going through the trouble of finding kin who might secretly resent her, adding to her headaches.
It was better to spend her energy training common jellyfish into summons.
Summoning Beasts trained this way would not only be obedient and easy to mold, but they would possess an innate, high level of loyalty toward her.
All it required was a dozen years of effort.
Rasa naturally reached the same conclusion.
He reached out, gently stroking Ziyou's supple cheek as he spoke thoughtfully.
"What breeds of jellyfish do you need?"
"And how long does it take for them to become Summoning Beasts?"
Ziyou pondered for a moment, her voice a bit uncertain.
"In principle, the rarer the species, the better."
"But the more precious the jellyfish, the longer it takes for them to awaken, and the lower the success rate."
"However, living within this concubine's Sage Land, the time should be halved. Common breeds will show results in two or three years."
"Kin of my own species would likely take seven or eight years."
Rasa sat up straight and made a decisive call.
"Then let's start with twenty thousand common jellyfish and another thousand of the rarer breeds."
Hearing this, Ziyou's rosy lips parted slightly. After a moment of hesitation, she spoke softly.
"Rasa, to raise so many at once... I fear I do not have the capacity to look after them all properly."
Rasa waved his hand dismissively, his tone radiating confidence.
"It's fine. If you follow the methods I teach you, I guarantee you can raise them brilliantly."
"As for the food for so many jellyfish, you needn't worry. The Hidden Sand will send everything you need."
By using modern aquaculture techniques supplemented by certain items from his system.
Rasa could easily raise three times that amount without breaking a sweat.
As for the resulting food problem.
The Hidden Sand might struggle with other types of provisions currently.
But when it came to jellyfish feed, they were far from lacking.
The oceans of the Ninja World were incredibly vast.
Yet due to technological limitations and various cultural reasons.
The level of oceanic utilization in this world was pathetically low.
Fishermen might catch fish in the shallow waters near the coast.
But even slightly further out, no fisherman dared to tread.
A single massive sea creature, which were common in this world, could devour a fisherman and leave nothing but splinters of his boat.
In this world, marine life growing to four or five meters in length was perfectly normal.
The near-shores were dangerous enough, let alone the deep seas and open oceans.
Furthermore, even if a fisherman risked his life to catch something.
With the current traditional transport methods of the Ninja World.
The catch would likely rot before it ever reached a distant market.
It had to be sold off cheaply and locally.
Over time, the enthusiasm for deep-sea fishing had withered away.
As for ninjas.
Though they had the strength to deal with massive sea beasts.
Unless it was absolutely necessary, no ninja would waste their time on such things.
A standard ninja village wouldn't even post missions for simple fishing.
Consequently, the deep seas were practically overflowing with fish and other marine life.
With one order from Rasa.
He could guarantee that thousands of tons of fish would be delivered the very next day.
Hearing Rasa's confident guarantee, Ziyou pondered for a while before finally nodding.
"Then this concubine shall instruct the Steam Village to begin preparations later."
"Since Yugakure needs to be rebuilt anyway, we can use that as cover to expand the breeding grounds suited for jellyfish."
Rasa lay back down, his hands gently stroking Ziyou's silky purple hair.
"What is the approximate ratio for a jellyfish to become a Summoning Beast?"
Under Rasa's touch, Ziyou squinted her eyes comfortably and replied with some uncertainty.
"This concubine is not entirely sure."
"In the waters where I lived, perhaps only one in three hundred jellyfish would become a summon."
"In a controlled breeding environment, even within my Sage Land, the ratio might be a bit lower—perhaps one in four hundred?"
Hearing this ratio, Rasa wasn't disappointed; instead, he felt a flicker of surprise.
Even if only one in four hundred became a Summoning Beast.
That was an absolute steal.
After all, he was only bringing in ordinary jellyfish.
Given their lifespan, growth rate, and breeding speed.
Once those initial summons began to breed with each other, the next generation would likely have a much higher success rate.
The existence of Summoning Beasts was a significant boost for ninjas of any level.
In a few years, the average strength of Sunagakure would likely jump several tiers.
At that point, he could pick out the strongest, longest-lived jellyfish to sign contracts with his women.
Thinking of this, Rasa began to wonder if he should specifically search for Immortal Jellyfish (Turritopsis dohrnii) to cultivate.
After all, that species possessed the miraculous ability of rejuvenation.
He wasn't sure if that specific breed existed in the Ninja World.
But if it wasn't here.
It likely existed in the world of Manyū Hiken-chō.
Perhaps he should try his hand at researching and developing new species of jellyfish?
With that thought, Rasa blinked, his eyes deep with calculation.
