Chapter 40

*****

Returning home, all four took a cool shower, and collapsed into their beds. Ichiro and Kenshin were physically exhausted, and the Third and Fourth were mentally exhausted. It was the first time they participated in a battle in which their father was almost killed, it left an indelible mark on their fragile minds. Everyone made a promise to train harder so that next time, if Ichiro wasn't around, they could protect their father and become a reliable support for him.

Kenshin didn't have any particular worries about killing Kaito. He knew that it had to be done, at least because he was the only one who knew Kenshin by sight.

Ichiro, in turn, had severely depleted his chakra reserves, so he needed rest. After taking a shower, he trudged to his bed, and instantly fell asleep, skipping dinner.

Aya and Natsumi were in shock, and having abandoned everything, they rushed to the bedroom, starting to question Kenshin about what had happened. He briefly told them the whole story, not forgetting to mention Kaito's death, but did not say exactly how he died.

"The most important thing is that everything is fine with you all!"

said Aya. She was not at all upset by Kaito's death, but the possibility of losing another family member scared her to the point of trembling, so Kenshin pulled the girl to his bed and hugged her.

Natsumi took this story without surprise. She had never participated in such battles, and they did not frighten her. She was only glad that Kenshin and the children were all right, simultaneously lecturing him to stop getting into trouble.

Kenshin understood even without her moralizing that if even the weakest Chunin turned out to be their opponent, they would all stay there, torn to pieces. Even Ichiro with one tomoe was not an opponent for Chunin. Kenshin assumed that for a fight with Chunin, Ichiro needs to have at least two tomoes, or a chakra quality of three units.

After resting for about an hour, Kenshin and his two children were invited to a family dinner. Aya did not wake Ichiro, and only stroked his hair, wondering how quickly her baby, whom she held in her arms, grew up and became a strong shinobi.

Over dinner, Kenshin once again briefly discussed the situation with his sons, and praised them for their valor, again urging them to train harder. After dinner, everyone went to their rooms, and after a while went to bed.

Kenshin had planned the "fertilization" of two wives for tonight, but after such a hard day, he did not have the strength for it. In addition, the Fifth and Sixth were only recently born, and could not do without mothers for a long time, so Kenshin postponed this undoubtedly important matter until tomorrow, and went to bed.

The next, 106th day, Kenshin spent planting blue sage. He had already read a pre-purchased book on the care of this very valuable plant, and knew what conditions he needed for growth, so Kenshin had only to set up the formation, and in about ten days wait for the first harvest.

Ichiro has not fully recovered from yesterday's chakra depletion, so he devoted the whole day to teaching his younger brothers. He conducted several sparring sessions with them, and explained how to properly concentrate the chakra on the feet in order to be able to stay on the wall or water.

The Third and Fourth were very capable students, and progressed before our eyes. By the evening, the Third began to be able to linger on the wall for half a second, and full mastery of this ability for him was a matter of several days.

In the evening, after dinner, Aya and Natsumi put the children to sleep in the next room, and fell into the clutches of the insatiable Kenshin. Overnight, the trio of insatiable lovers compensated each other for the last week before giving birth, when the girls were in the last stages of pregnancy and could not satisfy their man.

After the two girls fell asleep tiredly, Kenshin focused on his "status" and distributed the skill point from the seventh level received into the skill "Formation Creation", raising it to the fourth level, then wearily went to bed.

When Kenshin woke up the next morning, he found that he knew a little more about formations than before. He learned the ways in which the old formations could be changed and improved. Of the new knowledge, the most important in his opinion were the "animal control formation" and the "energy suppression formation".

The formation of animal control was applied to a special collar or animal skin, and made it absolutely submissive, and a little manageable within the limits of the intelligence available to the animal.

The energy suppression formation was usually applied to shackles or special cuffs, and served to capture magicians. Kenshin liked this formation very much, but it required refinement for the chakra, since at the current level of knowledge, Kenshin could modify and change the available formations, and in theory create completely new and unique formations.

The thought of the impossibility of adding strong kunoichi to the harem has been bothering Kenshin for a long time. He absolutely did not want to capture strong women with the help of his sons, and then rape them bound.

Inspired by new knowledge, after breakfast Kenshin plunged into rethinking new knowledge, and an attempt to "force" the formation to perceive the chakra instead of magic, since he absolutely understood exactly which node in the formation was responsible for this.

During the day, he called Ichiro and Natsumi several times, and asked them to release the chakra to the right place on the formation, and then plunged into work again, drawing and erasing the lines again, trying to achieve at least some result.

The following days were a copy of the previous ones. The elder sons of Kenshin trained, and the younger ones grew up. Kenshin himself was always working on improving the formation, and he didn't have time for anything else. Aya and Natsumi, as usual, did household chores, and often rested in the pool, where Kenshin occasionally looked in, followed by several hours of reckless sex and relaxation.

On the 108th day, the Fourth also learned to stay on the wall for half a second, and the two brothers kept jumping on the surfaces of the mountains closest to the house, honing their skills.

On the 109th day, Kenshin, after lunch, as always, was sitting and drawing formations on the ground, but suddenly he heard Ichiro's voice over the mental link: "Father, go to the gym, you should take a look at this!"

Kenshin immediately abandoned all his business and headed to the gym. When he entered, he immediately saw Ichiro, and the Third and Fourth standing next to him, they vied with each other:

"Father, you have to see this!"

Unable to contain his emotions, said the Third.

"Yes, Father, look, it's incredible!"

confirmed the Fourth.

"What should I see?"

Kenshin asked with interest, not noticing anything unusual.

"Here, Father, look carefully!"

said Ichiro, and threw a shuriken at a wooden manikin standing at the end of the room.

Kenshin strained his eyes, trying not to miss anything, and opened his mouth from what he saw. The shuriken did not reach about a meter to the manikin, abruptly disappeared, and stuck into the head of a wooden manikin.

"Holy shit! Ichiro, are you in control of this?"

Asked Kenshin, unable to contain his surprise.

"Not always, but I think with training I can not only improve every throw of the shuriken, but also increase the distance!"

said Ichiro proudly.

Kenshin immediately started all kinds of tests and checks to find out the nature of this ability and its prospects. For example, it was found out that this is not just a shuriken acceleration, but a kind of "teleportation". Kenshin and his two sons specially stretched a dozen threads at a distance of 50 centimeters from the manikin's "face", and after the Ichiro throw, the threads remained intact, but the face was not.

But this ability had its drawbacks. For example, Ichiro could not "teleport" a shuriken to a place that he did not see with his eyes. After Kenshin pulled a long cloth in front of the manikin, Ichiro's ability stopped working, and the shuriken flew on, breaking through the fabric.

But even with this "minus", the ability was extremely strong and dangerous. After Natsumi saw Ichiro's throw, she was no less shocked than Kenshin, and stated that not every Chunin would be able to dodge such a throw.
