The entire 198th day Kenshin rested, spending several hours upgrading the exo-suit. New ideas kept coming to him on how to optimize energy accumulation and distribution, and in the evening while lounging in the pool with three beauties, an idea suddenly came to him on how to distribute the energy storage across several blocks and at least double the battery capacity.
He instantly jumped out of the pool and, to the shocked looks of the girls, ran to his office so as not to lose inspiration.
"Kasumi, girl, good you came. Look at this brilliant idea!" Kenshin said proudly and unfolded the exo-suit.
"Um, you added several additional energy storages?" Kasumi asked with a smile.
"Not just that. All energy distribution nodes are now connected to all batteries. Now there's no need to fear that damage to one battery will render the suit useless. Now I have three!" he said with a laugh and lightly kissed the girl on the lips.
Kasumi was aware of his formation abilities and often helped with advice. Kenshin planned to teach her the skill but decided to wait until after the baby was born. He knew that even teaching the basics via telepathy would take at least several days.
"Still, this suit is very weak. It gives you a bit of speed, but even so any peak Genin of the Nara clan could catch up and destroy you…" Kasumi said with a sigh. More than anything she didn't want anything to happen to Kenshin, and she was uneasy that he wasn't planning to sit home his whole life but wanted to participate even in combat missions.
"Weak for now. With current knowledge and growing physical strength, I think I can raise speed to Chunin level. And if I finally grasp psionics and integrate it into the suit…" Kenshin trailed off dreamily, thinking of incredible prospects.
"In serious battles a Chunin is no more than a fish on the chopping board! Besides, how will you overcome the natural limits of the physical body? How will you handle the huge overloads from collisions with powerful strikes?! Shinobi have chakra to dampen all that, but you'll have no choice but to be a ball that withstands the blow but immediately flies into the sky!" Kasumi said in a dissatisfied tone.
Kenshin seriously thought about her words. Dampening inertia from powerful blows was one of the first questions he asked the very intelligent girl. Asking Natsumi and especially Aya was pointless—the former vaguely understood what it was about, and for the latter it was all a dark forest. Kasumi, on the contrary, intuitively understood the simplest laws of physics and could give at least some coherent answer.
When exchanging blows between strong shinobi, several parameters came into play. The very first—physical protection. Skin, flesh, bones had to be very strong to withstand a counter blow. If the blow was incredibly powerful, when blocking the defender would have broken or torn-off arms, and the blow could easily rupture his chest.
The second—chakra. Kasumi used official terms for chakra differences, but for Kenshin the term "chakra quality" was much more convenient. Shinobi with stronger and more powerful chakra much more easily passed impulse through themselves and dissipated it in all directions, not allowing themselves to be thrown back or shaken.
The third and fourth were control and quantity of chakra. Control allowed much easier passage of the most powerful impulses through oneself and dampened a huge part of the damage, not even allowing harm to flesh. Quantity of chakra played a lesser role, only slightly easing the load on the shinobi's body. This parameter reached a completely different level of effectiveness when it came to someone with chakra volume close to a tailed beast. According to Kasumi, one could break fists on the faces of such shinobi, leaving only small bruises on the enemy's face.
"I'll think of something…" Kenshin muttered tiredly, rubbing his temples. His knowledge in formation creation was not sufficient to easily create an exo-suit capable of harmlessly restraining the most powerful blows for the user and instantly dissipating impulses arising from the collision of two objects.
"All right, sorry for ruining the mood…" Kasumi answered with a sigh and hugged him, kissing his lips. She didn't want to be rough with him, but she was very annoyed that Kenshin couldn't drop the idea of participating in combat missions.
*****
For the next several days Kenshin did nothing but upgrade the suit and spent two hours a day analyzing the Nara clan's combat style under twentyfold focus. Thanks to perfect memory he clearly remembered every movement and every note from Kasumi. All that remained was to structure this information and make it convenient for transfer to his sons.
In the evening of the 201st day he finally impregnated his two wives burning with desire again. Kasumi was very jealous of her friends and promised to squeeze all the juices out of Kenshin after giving birth.
The entire 203rd day Kenshin spent on pins and needles. Kasumi was very nervous and didn't let him far from herself. She was preparing to give birth to her first child and was very tense.
Aya and Natsumi tried to calm her, but that day Kasumi refused to use logic and common sense, completely surrendering to her fears and prejudices.
Kenshin decided that sitting and waiting was a waste of time, so he went to his office to continue structuring the Nara clan's combat style.
"KENSHIN!"
Kenshin, sitting in lotus position, flinched and opened his eyes. He was in complete shock and immediately rushed to the second floor. Until now none of the girls could initiate telepathic communication, but Kasumi, having arranged a powerful empathic impulse, succeeded.
"UUUF, KENSHIN! GOD, WHAT'S HAPPENING!" Kasumi exclaimed, experiencing the strongest panic.
"Shh, your water just broke, everything's fine." Natsumi said, stroking her head.
Kenshin instantly jumped to his third wife and, taking her hand, began empathically radiating complete calm.
"Everything's fine, girl. Nothing bad will happen. Now do as we agreed. Relax and just breathe." he whispered to her in the most calming voice possible.
Kasumi calmed down a bit and breathed heavily, gradually normalizing her breathing. Kenshin's words had a hypnotic effect on her, making her almost completely relax and surrender to natural birthing instincts.
Ten minutes later, completely unexpectedly for Kasumi herself, the room was filled with the loud cry of a newborn child.
"Shh, don't cry." Kenshin whispered, looking into the completely black, unblinking eyes of the baby, and handed him to the mother.
"Everything's fine, dear. You did it. Look what a beautiful baby you gave me!" Kenshin said with a smile, handing over the child and kissing Kasumi on the forehead.
"Aaah, god, he's so beautiful…" she whispered, unable to hold back tears of joy. All her sadness instantly vanished when the baby found mom's breast and silently began to eat.
Kenshin couldn't wait to see his baby's characteristics.
Name: Fifteenth
Age: 0.1 days
Talent level: 36
****
Seeing the characteristics of his youngest son, Kenshin couldn't hold back a joyful smile. Kasumi saw his pleased expression and sighed inwardly with relief. She understood that Kenshin would first pay attention to the talent level and held her breath waiting for the verdict.
"Ha-ha-ha! What a wonderful child! Kasumi, you're real gold! Talent level thirty-six!" Kenshin exclaimed, delighting everyone present.
The baby wasn't the least bit scared of Father's loud cries—on the contrary. He liked this voice and began eating with doubled zeal.
"That's right, baby Fifteenth, eat, eat. Grow big and strong. We'll show your cousin grandpa who's the genius in shadow manipulation!" Kenshin declared with a laugh, in the best of spirits. Fifteenth exceeded all his bold expectations and was much more talented than any of his older brothers.
Hearing Kenshin's praise, Kasumi was incredibly happy and gently stroked the baby's back, not wanting to interrupt feeding for a kiss.
"Thirty-six… That's solid Jonin level!" Aya said in surprise, unable to believe her friend had given birth to such a genius. Jonin were considered the elite of the shinobi world and occupied all leadership positions. A Jonin could easily decide the fate of small villages like Shinto and kill all dissenters with a wave of his hand. A Jonin from Konoha who destroyed a small village faced only a reprimand and fine, and only in rare cases something serious, so Aya had feared them since childhood.
"Said the girl who gives birth to children with Sharingan…" Natsumi answered with a smile, and everyone chuckled quietly.
"Good, Kasumi, you need to rest. Girls, it's time for us." Kenshin said and, kissing his wife and child, headed for the exit.
