Hakai v0.5
"My clone is sorting my stuff, he'll cover for me."
"And then what? You plan to send him to the village and hide here?" chuckling faintly, Tsunami gently squeezed Naruto's cheek and whispered 'You know you have to go.'
"I don't want to..." Shrinking into Tsunami's embrace, Naruto hid his face in her chest as he wrapped his legs around hers and held on tightly.
"I never thought you could be so spoiled" Chuckling, Tsunami gently stroked Naruto's hair and fell silent.
After a few minutes where the duo just held each other and enjoyed each other's warmth, Naruto looked up at Tsunami and murmured "One last time?"
"You don't know how much I'd like to do it..." With a soft smile, Tsunami continued "But I'm at my limit."
Frowning slightly, Naruto thought for a moment and brought his hand towards Tsunami's chest, then closed his eyes and after a few seconds, a crimson light covered his hand and in a matter of seconds, her exhausted face was filled with vitality as a vivid glow covered her eyes.
Opening her eyes a little wider in surprise as she felt an energy she hadn't felt since her youth, Tsunami stared at Naruto while his hand continued to glow and a rare warmth covered her entire body.
After a few more seconds, Naruto opened his eyes and withdrew his hand, then smiled and asked "How do you feel now?"
"Better than ever..." Looking at her hands while clenching her fists, Tsunami asked with surprise "What did you do?"
"I don't know" Shaking his head slightly as he began to gently kiss her breasts, Naruto continued "I think I gave you some of my vitality."
Frowning slightly, Tsunami asked "What does that mean?"
"It's part of a new ability I have that I don't fully understand...I just felt I could do it and I did it."
"I'm not talking about that, I'm talking about giving me your vitality."
"It's exactly that. Give you from me a small part of my vitality."
"Do you know what vitality means?"
"Of course I do, I'm a ninja."
"And do you know what that means to a person?" With an even more annoyed face, Tsunami asked.
"I know what you're worried about, but believe me, it's nothing to me" Smiling softly as he noticed her concern, Naruto rested his head on her breasts and continued "You really don't have to worry about me. I am an Uzumaki and my vitality is at least 10 times more than any Kage and at least 1000 times more than any civilian. This is but a drop in the vast ocean of what I have."
"That doesn't mean you can waste it just to have sex" Squeezing Naruto's cheeks tightly, Tsunami continued with a strict tone "Promise you won't do this nonsense again."
"I'm not going to promise anything" Smiling despite having his cheeks squeezed tightly, Naruto continued "What I did is not only for sex, but it will help you stay energetic and healthy for a long time. I don't regret it in the slightest."
"Y-you..." With quivering eyebrows, Tsunami was silent for a moment suddenly enveloped Naruto with her whole body, then turned and laid him down to the bed as she lay on top of him.
"I never thought I'd say this, but I love it when you scold me" Chuckling as he looked at Tsunami's annoyed face, Naruto continued "You don't know how dear it makes me feel"
"Silence" Snorting, Tsunami lowered her hands and grabbed Naruto's yukata, then opened it and pulled out his already erect member "It'll just be one last time and you'll leave, understood?"
"Understood~"
Biting the corner of her lips, Tsunami gently brought the glans towards her opening and gently rubbed it along her slit for a few seconds, carefully soaking every inch of his member with her fluids until she finally guided it into her little hole and slowly lowered her body.
'God...' With a satisfied smile as the intoxicating tightness enveloped his member, Naruto firmly held Tsunami's thighs and thought 'What's a little vitality in exchange for this awesomeness?'
"Mmmnh~"
***
"497, 498, 498, 499, 500" With sweat running down his face, Naruto concentrated all his body weight on his arms while his legs pointed skyward as he did push-ups and the handle of the giant sword on his back brushed the ground.
Pa
Hearing the familiar sound, Naruto looked up into the distance and noticed the faint smile on Sasuke's face as he stared at his empty hand.
'So he finally managed to blow up the rubber ball' With a slight smile, Naruto put strength into his hands and pushed himself into the air to land on his feet.
A week had passed since they left the island and set out on their way to the village.
After a delay of more than two hours due to Naruto's constant excuses to extend their stay, finally the group left and without the need to detour because of the large amount of food they brought thanks to all the leftovers from the banquet, they could continue on their way without major problems.
During this time, although they did not train as hard as before, obviously they would not leave aside their training and made sure to do just enough to improve, but keeping enough energy to defend themselves in case of emergency.
Naruto, as on the island, focused on making his clones train the wind element while he trained his body, finally achieving some progress in his element.
Although he still can not use the wind to propel himself as he had planned, he already has enough ability to infuse his element in objects as fragile as a branch or a stone, even if only for a few seconds, while in basic control, he can form wind spheres with similar effects to the Rasengan but with much less raw power of attack and with more raw cutting power.
Of course, he still does not achieve what he wants and he knows he is far from making a Rasen Shuriken without the need of clones or making gigantic storms like other ninjas he has in his memories, but for less than a year of training, he can not be more satisfied with the results.
His body was no slouch either, and the fact that he can now swing the sword repeatedly without having to take the time to stabilize himself again, shows how much he has managed to advance in this time, going from not even being able to lift it to at least being able to control it even for a few minutes.
Walking over to Sasuke with a smile on his face, Naruto looked at his hand and spoke to him "Do it again."
Nodding, Sasuke took another rubber ball from his side and after a few seconds where the rubber ball shook violently, the ball exploded and the rubber was propelled everywhere.
'I never thought Sasuke would do it first than Sakura...' Nodding as he turns to the girl who was doing push-ups in the distance, Naruto thought 'I guess the fact that she has so little chakra slows down her training quite a bit no matter how much talent she has to control it'.
"What's next now?" Getting up while wiping the dust off his clothes, Sasuke asked.
"With that you already have enough to make my Hakai" Approaching the tree next to Sasuke, Naruto put his hand on the trunk and after a few seconds, a giant hole formed in the middle of the tree as a large amount of sawdust fell towards the ground "Try it."
Nodding, Sasuke walked over to another tree and placed his hand on it, then stood still for a few seconds frowning slightly.
"..."
crack
After a minute, finally a loud sound of wood shattering echoed around him, as Sasuke withdrew his hand with a slight shudder and a fist sized hole about 4 centimeters deep formed in the trunk.
Turning his gaze to the log that was almost split in two and then the log he smashed, Sasuke frowned slightly and asked "Why are they different?"
"Because you are just learning how to do it, you still need to polish your control a lot and it is already a miracle that you have been able to do it in such a short time" Patting Sasuke's shoulder, Naruto continued "Now continue with the rubber balls but this time focus on making your chakra flow inside them and keep the flow with ease without having to make more effort and without it exploding. This is the hardest part to learn, so it will take you a while."
Still with slight displeasure, Sasuke nodded and sat back down next to the rubber balls, then fell silent for a moment and looked up at Naruto "You said you already know how to defend against this skill... I managed to do it but I can't think how to avoid it."
"You want to know the how?"
"Yes"
"Promise to keep it a secret?"
"Mn"
"To cause the smashing, you have to flow your chakra and well, do what you already know" Looking at his hand, Naruto continued "But that's totally impossible if the enemy forms another chakra layer where you try to flow yours, since the two chakras will collide and end up nullifying the technique"
"That's your idea to defend it?" Frowning even more, Sasuke continued "For that you have to learn how to form chakra layers in specific parts of your body and have the ability to form it before the enemy injects his chakra, something totally impossible unless you have beastly chakra control like yours."
"I said I know how to defend against this, I never said it will be easy" Shrugging his shoulders, Naruto continued "My chakra control is already at a level where I can do that with ease and in less than a second, so my method of defense is useful for me."
"But not everyone is a monster at chakra control like you are."
"And that just makes my technique even more special" Smiling slightly, Naruto continued "You saw how useful it is and you already know how hard it is to defend against it... even though it's hard to learn it and even harder to learn how to defend against it, you easily understand its great usefulness, don't you?"
"Yes..."
"Indeed... it could also be improved" Thinking for a moment, Naruto walked towards another tree and placed his palm on the trunk.
Crack Crack Crack Crack Thump
With a loud clatter, Naruto withdrew his hand and watched his handiwork with interest.
Just like the other tree, a gigantic hole formed in the center of the trunk and went through it easily, but unlike the other tree, giant gashes expanded along the entire length of the tree with the base of the hole and with nothing to catch it, the tree fell heavily backwards.
"What did you do now?" raising his eyebrows in surprise as he easily understood how lethal those cuts could be, Sasuke asked.
"Mix in some of my wind element..." Looking around the surroundings of the hole and seeing the giant cracks opened by the wind, Naruto muttered "I think this will really make it totally impossible for anyone to survive this attack."
"You might consider it the definitive version?"
"I'd say it's more of a crutch" Shaking his head, Naruto continued "I have in mind to improve my control enough that I can quickly expand my chakra all over my target's body and directly shatter him into pieces without having a single limb intact, while this only shatters a specific area and then expands his attack to the sides with the wind cuts"
