Time passed with its usual clinical efficiency in the Walt household. Dan's eldest, Sam—Rin's firstborn—had reached fifteen. He was no longer the toddler shadowing his father but a young man on the cusp of adulthood. His siblings from the first wave—Sophia, Amy, Leon, Hoshi, and Nina—had followed suit, now sturdy teenagers with the family's signature sky-blue hair and piercing gaze.

  Nine years of unrelenting, disciplined training since the age of six had forged them into something remarkable. Their physical strength, speed, and endurance were far beyond what anyone would expect from adolescents. But what truly satisfied Dan was the awakening of their Kekkei Genkai. Every single one of the first twelve children had unlocked the bloodline limit at different stages, some as early as eight, others by twelve.

  This inheritance granted them massive chakra reserves that dwarfed those of most adult shinobi. Their control was equally surgical, allowing them to manipulate energy with a precision that opened the door to the most complex techniques. Over the years, Dan had taught them his silent movement technique to cut through air resistance and his lethal thread arts. They now practiced these deadly, invisible skills in a vast, secluded training range Dan had cleared far from the living quarters.

  Water training remained the cornerstone of the Walt regimen. Dan had set a non-negotiable minimum: every child had to be able to train at a depth of 200 meters. Anything beyond that was a personal challenge. Currently, Sam was leading the pack, comfortably enduring the crushing pressure at 120 meters during his daily sessions—a feat that made Dan quietly proud.

  Dan's standard for his offspring was absolute: every son and daughter had to reach a level comparable to a "Kage." This was the mandatory baseline for the Walt family. Those who reached it could choose their own path; those who didn't were confined to the estate until they succeeded. To aid them, they had the Kekkei Genkai and the promise of the first-tier Vitality Seal, which Dan planned to bestow once they hit their physical prime around age thirty-five to maximize their potential and longevity.

  The family had grown exponentially. Dan was now a father to thirty-four children. From infants to teenagers, the camp was alive with a sea of blue hair. Seeing them all together—his own blood and legacy—filled Dan with a profound sense of accomplishment. His wives, too, had evolved. Enhanced by the first Vitality Seal and years of practice, Rin and Kali had finally hit the Kage-level benchmark. As a reward for their devotion, Dan prepared to grant them the improved version of the seal he had promised years ago.

  During this era of growth, Dan finally perfected his "Chakra Radar." After years of trial and error, he could now emit pulses that mapped everything within a thirty-kilometer radius. This gave him a god-like view of his surroundings without moving an inch. He could track large animals, human movements, or geographic shifts—a vital tool for staying ahead of shadow-dwellers like Black Zetsu.

  Following a late-night session, Dan drifted in the air on a chakra platform, staring at the brilliant stars. He reflected on his journey from a lone man lost in a strange world to the patriarch of a thriving dynasty. He smiled faintly. The road to true immortality was still long, but he was moving—step by step, day by day—toward the future he had envisioned.
