"No way!" Kasumi exclaimed in shock upon hearing Hitomi's words.
"So you learned to awaken the flower of longevity?" Noriko asked with interest, wiping meat fat from her lips with a finger.
"Yes," Hitomi replied with a slight smile, feeling wonderful.
"Kenshin, teach me!" Kasumi declared with burning eyes, nearly making Kenshin choke on hot tea.
"Ahem... Me?!" he exclaimed in surprise, as not only Kasumi but all the girls nodded furiously.
"You can extract that knowledge from her mind and share it with us all!" Natsumi said, fueling the excitement.
"Yes! I want it too!" Karin declared joyfully, not understanding but eager to join.
"Karin, behave!" Keiko shushed her.
"But Daddy lets me talk about whatever interests me!" Karin replied discontentedly, and before Keiko could react, scrambled onto Kenshin's lap.
"Yes, but you can't disobey Mom," Kenshin said gently, making Karin feel a bit ashamed. She went to her mother, hugged her softly, and whispered "Mom, sorry."
Everyone melted at the sweet scene until Kenshin sighed deeply and said:
"Fine, I'll share the knowledge, but if you tease me after..." He hinted threateningly at his giggling wives, then used telekinesis to flip up all the women's skirts except Makoto's and Karin's.
After dinner, Kenshin meticulously analyzed and transmitted the knowledge from Hitomi, who advised the women to train their tenketsu often and get used to accumulating chakra in their genital areas.
By the end, he felt like a squeezed lemon and tried to forget Hitomi's memories and sensations, but his perfect memory wouldn't allow it. All he managed was to bury them deep and avoid touching them.
Returning to his room, he found Makoto sleeping sweetly on his bed. Not wanting to wake her, he undressed and slipped under the covers, tenderly pressing her young body to him.
Though Makoto was no longer skinny and fragile, she still didn't look sixteen, making Kenshin awkward about showing affection to such a youthful girl on other days. But exhausted this time, he unashamedly placed his right hand on her small breast, felt the little mound, and blissfully fell asleep.
The following days were a fun routine. Kenshin kept training and drilling Karin, while the women prepared for births and mastered the "flower of longevity."
On the evening of day 459, Keiko finally gave Kenshin his first son, named Forty Seventh. The baby was surprisingly quiet with 41 talent points, fully meeting Kenshin's expectations.
Besides family matters, Kenshin was fully occupied with incoming crowds. Once peasants and refugees learned the Nakayama Family offered good work, many tried their luck, flooding toward the fortress walls.
Kenshin accounted for nuances, so workers built houses far from fortress borders, with his sons helping with the heaviest physical labor as able.
In just two weeks since Aketo fled to Nakayama territory with his family, everything changed. Over fifty workers built ten houses, but the influx strained Kenshin's mind, as he couldn't keep appointing foremen and overseers fast enough.
One of the buildings was built as a school that all children and teenagers were required to attend. Kenshin didn't like forceful methods of motivation, so he acted much more cleverly. To the students who studied well, he issued additional rations in the form of chocolate and honey sweets that were astonishing for this world.
Random Genin were also involved in the construction, and they were paid quite generous wages in the form of the same unheard-of delicacies or cash.
There was so much to do that Kenshin temporarily stopped analyzing his sons' experience and often switched entirely to pondering the strategy for developing his small settlement.
However, what had been impossible for one person in the past world was successfully implemented by a person with two streams of consciousness, perfect memory, and accelerated thinking.
Some of his sons were not entirely pleased with their leadership positions, but Kenshin accepted no objections, for an elite shinobi must first and foremost be an excellent manager and a candidate for high positions in various structures, from clan elder to members of the High Council.
Of his forty-five sons, about fifteen were constantly on the road, carrying out various assignments, primarily concluding trade agreements with different trading organizations.
Accepting Konoha as suzerain allowed Kenshin to engage in such matters on their territory without much trouble, and the locals only encouraged it, for the Nakayama Family showed itself in a good light, honoring all agreements even with simple peasants.
Kenshin's plan was very simple. Even five hundred kilometers from Konoha, he felt this lull before the storm and knew that high-ranking people had no time for him right now. The Chunin Exam was approaching, and the number of internal intrigues had increased so much that everyone didn't care about a small, unnecessary mercenary organization that had started some construction on its territory.
Kenshin's top priority was concluding various contracts with promising trading organizations to spur entrepreneurs and indirectly force them to develop this region.
This task was far from trivial, for even incredibly useful and technological things were perceived by many people in this world as garbage. Only delicacies enjoyed incredible demand, news of which had spread through all nearby regions, so small traders or envoys from trading organizations began arriving at the settlement for reconnaissance.
Kenshin didn't meet with any traders himself, letting his sons prove themselves and conclude profitable or less profitable deals on their own. Only occasionally, in the most serious matters, did he oversee the negotiations, not allowing his children to be deceived too badly.
It was one of the luxury items that caused yet another serious conflict on Nakayama Family territory.
