An hour later, Hitomi finally completed a detailed examination of Karin's entire body, as well as tested her chakra, and concluded that it was far more concentrated than her mother's.
Over the past few weeks, Hitomi had fully mastered all the modern equipment, while constantly honing her practical iryonin skills, combining both approaches wherever possible.
To speed things up, Kenshin had transferred extracts of the most useful medical knowledge into the heads of all her sons ranked Chunin or higher, and the results came quickly. The talented sons greatly assisted their mother by suggesting new ideas and solving problems where she hit dead ends.
Their main research focus was cell division. Without iryoninjutsu, such studies would take decades, but with this art, progress was highly productive. Hitomi could watch cell division under healing techniques for hours.
And though the microscope couldn't detect chakra, observing the effects of various chakra concentrations in different proportions was enough. All data was meticulously recorded and classified using methods she developed herself.
Karin's powerful chakra surges became an excellent addition to the research, and Kenshin had to repeatedly cut his own hand for the little girl to heal her father's wounds.
Hitomi noted that regeneration from iryoninjutsu techniques and Karin's chakra differed like heaven and earth. Iryonin jutsu methods, compared to Karin's pure chakra, were utterly crude, clumsily forcing cells to divide without supplying them with energy reserves, causing the human body to deplete its resources much faster.
Karin's chakra, on the other hand, gently enveloped each cell, filling it with healing power and bearing all energy costs itself, without harm to the body. Hitomi didn't understand the deep processes but intended to thoroughly research this phenomenon.
The next week flew by unnoticed, and finally the day of Forty Second's coming of age arrived. After lunch on day 456, Kenshin personally handled the preparation for his chakra awakening, and was pleasantly surprised.

At the moment, Noriko's son was the most talented among all the boys, but also the most unmanageable. As he grew, he clashed with his mother more and more, refusing to obey, and was constantly beaten for it.
Kenshin tried not to interfere in their relationship, stopping Noriko only when she crossed all boundaries. However, Forty Second never complained or cried, just clenched his teeth and shielded himself with his arms from his furious mother's blows.
After his chakra awakening, Forty Second was truly happy and wanted to train 18 hours a day, eager to catch up to his older brothers and challenge each one.
Kenshin approved of his mindset but strictly forbade evil thoughts against his brothers or bullying the weak. Forty Second had no intention of harming his weaker brothers but passionately wanted to beat Ichiro and Fifteenth, who playfully defeated him with one finger when he was a teenager.
Over the past week, Kenshin had impregnated Hitomi, Aiyu, Kasumi, and Natsumi again. It was turning into routine, but he made sure to devote at least an hour to each. He usually spent nights with each non-pregnant woman in turn. With the arrival of television and more movies and series, boredom became less acute, and the women needed less attention.
With the help of Kenshin's sons and other workers, Aketo finally completed a two-story, twenty-apartment building, where former peasants and their families moved in.
Attracting decent refugees was no trouble, as cities were full of them, any willing to go to the ends of the earth for work, shelter, and protection.
About half the applicants were rejected, as street life turned people into animals, but the quota of twenty families filled on the first day. Kenshin just pointed directions, while his sons slowly mastered management roles.
The new residents of the big, warm house were overjoyed at agreeing to the dubious offer and risking the unknown. Receiving sacks of rice, potatoes, onions, and a bit of salt, the former refugees were more than content, and 100 cans of stew per family caused a real sensation, making Lord Nakayama's name known.
Kenshin didn't restrict movement, allowing returns home to invite more friends and relatives, provided they worked devotedly and obeyed the law.
Without delay, Kenshin quickly selected a dozen reliable, non-stupid women and infused their minds with knowledge equivalent to elementary school from his past world, but excised many subjects, leaving only essentials.
This was the first brick in building a new world's foundation. The more he analyzed his situation, the more convinced he was that success required technology and scientists—otherwise, even the "system" wouldn't save him and his loved ones from the universe's harsh laws.
Even past great shinobi couldn't escape old age and decay, leading Kenshin to conclude chakra alone wasn't enough to conquer universal laws. Besides chakra, he knew one promising way to fight life-and-death laws: a post-industrial world.
Humanity wasn't last on his reasons, and Kenshin was sure that even in failure, he'd save many lives and let this world bloom again, even after Tsukuyomi's eternal flower wilted.
