Half the night of the 426th day and the entire 427th day, Kenshin spent testing the available capabilities. First, he was delighted by the professional instructions for using everything he created.
Hitomi was so impressed by the various medical devices that, grabbing her little son, she rushed to the infirmary to explore the wonders of scientific and technological progress.
She was especially enamored with the latest medications, from fever reducers to the most potent tranquilizers, painkillers, and steroids. She could spend hours rapturously reading the detailed system descriptions of all the drugs, their compositions, and properties, but Kenshin allowed her only two hours away from maternal duties before the busty mom, pouting, had to go play with the baby.
Kenshin himself was enchanted by entirely different novelties. He finally had access to more advanced technology than before, and his attention was immediately captured by the wheel. Though wooden wheels already existed in this world, they were extremely primitive and couldn't meet shinobi needs.
Gaining access to the most modern wheel from his past world, Kenshin struggled for a long time to design a high-tech carriage. It took him two hours under hundredfold concentration to think through the prototype of the future cart.
The task was made vastly easier by the system's contextual hints, allowing Kenshin to effortlessly understand how to assemble any part and use the right tool for it.
Until evening, he assembled his own constructor set like a child, ordering various tools for quality carriage assembly. The system's assistance was so comprehensive that without it, Kenshin couldn't have finished in a month.
Thanks to his phenomenal memory and powerful mind, Kenshin handled the massive influx of information on the characteristics of everything his gaze fell on. This knowledge was so vast that any unprepared person would get a headache after reviewing just a few advanced alloys, tools, usage methods, and technical specs.
By dinner, Kenshin had only completed the base of the future elite carriage. The body was mostly aviation-grade aluminum, with the core structure from the strongest titanium alloy. He had no doubts about his four horses' strength but deemed armor on the carriage impractical—even the toughest alloys offered no guaranteed protection against top shinobi and heavily weighed down the design.
After a hearty dinner, the women took turns kissing Kenshin on the cheek and went about their business. The babies clung joyfully to their mothers and father. Keiko, fully settled in her new home, joined the ritual, lightly pecking Kenshin on the cheek.
Noriko was the only one who never kissed Kenshin and grimaced at what she saw as misplaced tenderness. However, defying her habit of leaving first, she sat in her place, silently waiting for the other women to leave the dining hall.
Kenshin couldn't miss Noriko's behavior, so he stayed until the end. When they were alone, he questioningly raised an eyebrow.
"I agree," she said calmly, looking him in the eye.
"Sure?" Kenshin asked, instantly serious.
"Yes. You've proven yourself a man of his word, tearing your tribe's enemies into countless pieces, and I have no reason not to trust you," Noriko said resolutely, holding his gaze. She was the only woman in this house who could withstand his intense stare without yielding or submitting.
"You understand you'll become my wife forever and bear my children?"
"That's the only thing bothering me! I agree to one pup every six months!" she declared, barely containing her displeasure.
"Pup? Don't talk about our future children like that. Every six months isn't enough. Once a month," Kenshin replied, unwilling to yield, feeling strangely awkward discussing such things.
"Once a month?! Do I look like a brood sow to you?! Every five months is my max!" she growled, barely restraining herself from hurling her plate at Kenshin. The only thing stopping her was an unfamiliar sense of closeness and kinship, as if he were the last member of her tribe and her only kin in this world.
"A month," Kenshin replied calmly.
"Four!" she exclaimed angrily.
"A month," he said indifferently.
"Three, or no deal!" Noriko declared, blazing with fury.
"Two is my final offer," Kenshin said, looking into her one eye.
"Arrr! Fine!" she growled discontentedly, feeling slight satisfaction at his concession. She needed to resist the terms to preserve her dignity and not seem like the other women in the house.
"Follow me," Kenshin said with a slight smile and headed to the infirmary to avoid potential side effects.
Noriko calmly rose from the dinner table and followed Kenshin unhurriedly, her wooden leg tapping on the parquet floor, eager to reclaim her lost health.
In the ward, Kenshin gently scooped Noriko into his arms and laid her on the couch. Since moving into the Nakayama Family home, her body had become much more attractive but still couldn't boast true beauty. The sickly thinness had nearly vanished, but her skin remained very rough, covered in countless scars.
Kenshin knew her character well, so he didn't dawdle and, without preliminaries, offered her the same contract Makoto had received.
"I still can't get used to your weird abilities…" she whispered and selected "YES."
Kenshin could only watch in stunned amazement as the girl lost consciousness. Her entire body flared with blinding light for a second, then began regenerating at tremendous speed like magic.
All old wounds and scars smoothed instantly, the flesh-overgrown eye socket began forming an eye's beginnings. Simultaneously, her scarred stump straightened, visibly growing a tibia bone layered instantly with flesh.
The process lasted several minutes, after which Noriko opened her eyes and looked around in surprise. First, she glanced not at her leg but at the guy nearby. Her heart fluttered, and the strong-willed girl barely restrained the urge to throw herself into his arms.
"How do you feel?" Kenshin asked softly, unable to resist gently stroking the warrior woman's head.
"Very strange… Like nothing changed, but everything did…" Noriko murmured cryptically, finally looking at her leg.
"It worked!" she exclaimed joyfully, jumping to her feet and squealing with emotion.
"Congratulations," he said tenderly, taking a white coat from the hanger and handing it to the improved girl.
"Oh!" she said surprised, surveying her fully naked body, then tossed the coat on the couch without a hint of embarrassment.
