Full four years have passed since Rin gave birth to her first child, Sam

  Life in the Walt family camp has changed significantly from how it appeared in the beginning, when it was just a group of miserable runaway girls who found shelter with a strange man living alone in the wilderness.

  Throughout these four years, Dan maintained his same strict and disciplined training program without any change or slackening. Every morning he wakes up before dawn and starts his usual routine: harsh physical training, diving into the depths of his training hole, developing his techniques, and nightly chakra refining sessions. He did not allow fatherhood or family life to affect his discipline and focus on his basic goals.

  But the new addition these four years brought was the presence of twelve small children growing and becoming more mischievous and active with every passing day. The sight is joyful in a way Dan cannot deny; whenever he completes his training or appears in the camp area, a group of small children immediately gathers around him, all with sky-blue hair and clear blue eyes blinking at him with curiosity, love, and playfulness. They cling to his legs, race to get his attention, and all speak at once with joyful little voices.

  Dan is still cold and a man of few words as he always was; his isolated nature has not changed in its essence. However, he sometimes pets his children during his breaks from training, carries one of them, or sits among them for a few minutes, listening to their small chatter in silence. His children love him despite his coldness, silence, and constant preoccupation with them; perhaps his lack of presence around them always creates an atmosphere of longing for him.

  As for the second important matter witnessed in this period, it was the significantly improved strength of the girls thanks to the training program Dan set for them, which they adhered to with seriousness and determination over the past years. The intensive physical training, which increases in intensity over time, added to the continuous training on chakra control and using it to enhance physical strength—all gave clear and tangible results. The girls are now much stronger than they were in their weak beginnings.

  Recently, Dan decided to take their training another step forward, which is teaching them his special movement technique. This technique uses chakra sharply in front of the body while moving to cut through air and atmospheric pressure, allowing movement at greater speed and in absolute silence. This technique will complete their arsenal of abilities and make them more effective in any potential confrontation; physical strength enhanced by chakra with advanced speed is considered a powerful and dangerous combination.

  He estimated, based on his precise monitoring of each one's progress, that the weakest of them in strength level should be roughly at the Jonin level today by this world's standards . a decent level that makes them capable of defending themselves in most ordinary situations. As for the strongest among them, Kali and Rin, who were always the most serious and fastest to progress in all training stages, they reached a more advanced level close to the ordinary Kage level by his personal estimation.

  But these are just rough estimates; he was not a traditional ninja, nor were his women. Their path in training was very different from the ninjas who will appear in the future. The power level in this world depends on many complex factors that cannot be reduced to simple classifications like Genin, Chunin, and Jonin; there is the nature of chakra, its amount, the quality of control, combat experience, used techniques, and many other factors.

  As for his twelve children growing up quickly, Dan had carefully planned their training program, which will begin when each of them reaches the age of six—the starting age he saw as suitable to begin formal training without negatively affecting their natural physical and mental growth. Starting too early before age six might harm the growth of their bones and muscles, which are still in the formation stage.

  The program he set for them is designed very carefully to be suitable for their ages: gentle exercises at first to build the physical foundation and develop fitness, then a gradual increase in difficulty as they grow and develop. He will start chakra control exercises with them from an early age as well, because that will be considered a great advantage for the Walt family; the earlier the training on chakra control begins, the deeper and more natural the control becomes over time.

  But although the program will be age-appropriate, it will be mandatory and compulsory for all his children without exception. Dan has strictly decided that in the future, he will set specific and clear power standards in the Walt family .standards that no family member can ignore or escape. All of them must achieve a specific minimum level as a mandatory requirement with no compromise. This minimum level was the lowest thing acceptable in his family; absolute weakness was not an available option for the children of the Walt family in a world full of danger.

  This decision came from a purely practical standpoint in Dan's selfish and pragmatic mind. The family in the future will need strong individuals capable of protecting themselves and the family as a whole. Dan thinks very far ahead .

  after hundreds, perhaps thousands of years. He wanted to ensure that the Walt family has a strong and continuous presence in this world.
