Training

In the woods."You will do tree climbing, but without hands,by applying chakra to the soles of your feet. To perform a jutsu correctly you need a very precise control of your chakra and you are far from being masters in this matter, this exercise will teach you how to control precisely the chakra in your body, even in movement, I advise you to take a starting speed" Each of the young ninjas took a kunai and started to run towards the trunk, Sasuke managed to make a few meters up before the bark exploded under his foot, it was more complex than he would have thought, too many chakra and the trunk couldn't stand the pressure, not enough and, sasuke looked at naruto who hadn't managed a step, and the foot didn't adhere to the surface. Sasuke looked at the mark of his foot in the tree, remembering the konoha accident, when he had accidentally shattered a tree, this training was perfect for him, it would perhaps allow him to reproduce what had happened.

" heheh that's pretty easy, sakura was already on top of the tree.

-It seems that Sakura has the best mastery of her chakra, a little disappointing from the future hokage and the last uchiha, says kakashi, thinking of the potential that both of them had."

These two looked at each other, the naruto look full of challenge, while sasuke's one seemed to accept it, with a touch of amusement. The three of them continued to practice. Sakura with her exhausted chakra rested at the foot of the tree while naruto and sasuke continued relentlessly. Unfortunately Naruto could not make any progress so he came to Sakura for help. After his discussion with sakura naruto's progress accelerated, but no matter what he did sasuke continued to get ahead. The gap was widening.

. A little later sakura went to their sensei.

"- Sensei, can I go take care of Tazuna's protection now?

-Yes you can, said Kakashi with a sigh.

-Seriously, aren't you going to take this opportunity to practice? I mean you're the weakest of us," sasuke added stunned.

-I... I... I... I just think about the mission, mumble sakura...

-you're a lost cause," said sasuke before repeating the exercise Sakura lowered his head with an empty gaze and left for the bridge.

The next day,kakashi was back on his feet and he decided to accompany sakura, while naruto and sasuke continued their training. After a while ,sasuke was at the top of a tree, standing horizontally, looking at naruto who had just fallen. Naruto raised his head, determination could be seen in his eyes.

"I like that look, it's not easy to not give up when, despite your efforts, you're still second, right? But it's that who give value to them, I'll be waiting for you at the top naruto " Then he left for the tazuna's house. On the way sasuke was thoughtful, he really hoped that, considering the efforts Naruto was putting into his training, he would end up making him feel pressure, a rival able to stimulate him, a pressure different from the one offered by the power of kakashi and zabuza. Even if that wasn't the reality of the situation right now.

The same evening ,in kakashi's room " sensei, I have a question

-Yes sasuke?

-You can increase yourself by circulating chakra in your body in the right way, but can you use something else, like elemental chakra?

-Mmmmmh, ninja generally use ninjutsu or impregnate their weapon with element, but the use of those on someone body is indeed possible, there are very complex and very rare techniques allowing someone to increase themselves in such a way, but the effect obtained depends greatly on the nature use and the most powerful is by far raiton, you should inquire about the raikage and its raiton: chakura modo (chakra mode), this is the technique who is largely responsible for his power, but it's also extremely dangerous if badly executed. You shouldn't try it, in spite of that kakashi knew very well that sasuke would attempt it, so he might as well give him as much information as possible.

-Thank you very much, sensei " sasuke went outside, so his hypothesis was right, he must have unconsciously changed the nature of his chakra through the stimulation of his sharingan, creating a technique similar to the one from the raikage.

Over the next few days sasuke continued to train. He began by using his normal chakra to increase his body power. Although he was successful, he felt that the process was unnatural, requiring a lot of effort and concentration, and he did not want to attempt to use lightning chakra with such poor mastery. Also no matter how much he practised he didn't improve. He had to find a way to increase his chakra control. The answer came to him one night when he remembered the fight between kakashi and zabuza, they had fought on the water. It was the same technique he used for training, but standing on the water and on a tree didn't seem to be the equal in term of difficulty. It didn't cost him anything to try.

On the beach, Sasuke was standing in front of the sea. He concentrated his chakra, approached the water and he pitifully sank. Sasuke came out of the water, soaked, with a broad smile on his face. "Definitely harder, the water reacts much more to the chakra and this reaction is constantly changing," Sasuke spent the last days of training trying to master water surface walking, coming close to standing on the water when Naruto finished tree climbing. After these 4 days of training , they decided, since they were approaching the estimated time limit, that it would be safer for all of them to go with tazuna, in case zabuza survived. The first day wasn't particularly existing. But the demon did not make them wait, the next day when they arrived on the bridge, all the workers had been slaughtered. A thick fog rose and the battle began.
