The next week, as expected, Fugaku came to help open his [Chakra Hearth]. The latter was surprised when Sasuke's chakra, as if it were a living creature, quickly spread through the channels without causing any discomfort. And its amount immediately jumped to the level of an Academy Student. But thinking that this was normal for the Uchiha, he didn't show any reaction on his face and simply congratulated him on officially becoming a Ninja. After modestly celebrating the occasion with his family and friends in Ichiraku, he continued with his routine. He did not immediately train his chakra, as he gave his body and channels time to get used to each other.
It's been two months. Not much had changed in that time. Sasuke was still spending time with his friends Ayame and Naruto. Of course, because of his new look, people were shocked at first, but soon got used to seeing Sasuke walking the streets of Konoha covered head to toe in leaves and goggles reminiscent of the Aburame clan members. On weekdays, he practiced, and on weekends he sparred. In the evenings, they fished or visited Itachi's favorite dango restaurants or spent time listening to Shisui's stories.
During this time, his chakra had finally fully, naturally calmed down. This meant that he could already begin to interact with it. The first and obvious action was [Meditation], which he had already completed. It was just that this time he decided to combine his [Chakra Sense and Meditation] to more quickly and accurately experience his additional source of energy, which would become important on his path.
It didn't take him long. Applying sensory awareness to his hearth, he quickly sensed its flow color [ Cold Dark Blue] and following it, explored every [Channel] in the [Chakra System], including but not limited to the [Eight Gates] and his [Tenketsu].
After that, he decided to start with the basic [Chakra Control] exercises. These were:
[Concentrations with Leaf].
[Tree Climbing].
[Walking on the Water Surface].
The first exercise didn't take him any trouble, as [Concentration] had already become second nature to him like most skills. Climbing the tree wasn't a problem either. After all, having an unclouded and pure mind, a sense of chakra both within himself and within the tree, it was also easy.
Due to this being a new experience, some problems when he stepped on the water did arise. After all, before, what seemed to defy logic was the norm in this world. Although it was unusual, but after a while, he got used to it and could walk on the surface of the lake.
It was a little difficult to get used to walking upright or upside down on different trees. The water was easier, except that during the waves it was difficult to stay in place because of the rare wind.
He felt that it would take him about two or three days to get used to this state and perhaps a little more to bring it to automaticity. That is, unconscious use of chakra in its exact amounts and situations, regardless of whether he is standing on water, a vertical surface, or somewhere else.
After finishing all these familiarization exercises with chakra, he started his daily body and mind training. After he was done, he went home and went straight to the bathroom to wash off the dirt he had accumulated during the day. Meeting his mother in the kitchen, he habitually sat down to wait for his food while he exchanged sentences with her about the previous day. After finishing eating, everyone said goodnight to each other as usual and went to their rooms.
Time passed and his Fifth Birthday arrived. A year where tragedy was inexorably approaching. But more about that next time.
Over the months, he had successfully fully maximized all of his new skills and techniques:
Chakra:
Level: Peak - [Genin].
(Was discovered by sensory observation of genin on common training grounds).
Special Chakra:
Level: Peak - [Elite Jōnin].
[Hand Seals: MAX!]
(Used to perform many ninjutsu, genjutsu, and other arcane arts with the exception of taijutsu. Invented by Indra Ootsutsuki, they are designed to assist shinobi in properly summoning and generating the chakra necessary to perform various techniques).
Basic chakra control skills:
[Concentrations with Leaf: MAX!].
(Can perform any physical activity such as Walking, Running, Talking, Physical Training, Reading, Games, and other things while maintaining concentration on the leaves attached all over his body without needing the [Parallel Memory] skill to do so. Since Attention and other previous skills were already pushed to their limits, this skill was more for familiarization).
[Tree Climbing: MAX!].
(Can easily run, jump, walk, crawl, cling to any vertical, smooth, rough, rough or other surfaces, trees, walls, roofs, ceilings, rocks, bridges, windows, etc., and fight without discomfort or nausea).
[Walking on Water Surfaces: MAX!].
(Can perform similar actions to the previous skill, such as running, jumping, walking, sliding on the surface of calm bodies of water and waterfalls, and clinging beneath its surface. It is the same with natural hot springs. Aside from clinging under the surface for a long time due to its temperature. Can do battle on the water).
[Active Chakra Recovery: MAX!].
(After an acceptable level of chakra depletion, Sasuke actively tightly twists his chakra clockwise and with [Meditation] and [Concentration], quickly replenishes his chakra without side or dangerous effects to his body).
Advanced Chakra Control Skills:
[Chakra-enhanced Power: MAX!].
(Sasuke concentrates chakra in his hand to increase the power of his attack. A technique that uses enhanced chakra control and concentration to increase his own power to monstrous levels).
[Chakra Threads:MAX!]
(Threads are created from extremely concentrated chakra, so they can be seen by anyone, not just the user. However, the user can also muffle the flow of chakra to hide the threads themselves and attach them to an object unnoticed. The threads increase the user's range of action, allowing them to control any object to which the threads are attached, such as a hidden weapon, at will).
[Chakra Shield: MAX!]
(Sasuke emits his chakra and it spreads around his body like a thin film, taking the form of a shield that can protect against any physical attacks as well as some techniques).
Form Transformation:
[Rasengan: MAX!]
(The maximum level of form transformation technique. This technique relies heavily on chakra control and does not require any hand seals. Based on the basics of chakra control learned in [Tree Climbing Practice] and [Water Walking Practice], [Rasengan] is chakra that has been twisted and then compressed into the shape of a sphere).
Genjutsu:
[Sharingan Genjutsu: Max!].
(Sasuke controls the flow of chakra in the nervous system of the target's brain, thus affecting his five senses. This is often used to create false images or trick the body into feeling physical pain. Genjutsu can also be used to control others - reminiscent of brainwashing - by presenting illusory suggestions to the victim. Sharingan genjutsu is done visually, requiring eye contact between the target and the user. P.S. no harmless animals were harmed).
[Chakra Masking: MAX!]
(By completing the preparation for the technique, the user is able to alter their chakra signature, causing it to appear larger, smaller, or non-existent due to the interference the user creates in their chakra, spreading this delusion to others).
[Chakra Suppression:MAX!]
(The technique allows the user to suppress both his chakra and that of his allies to the point where it becomes completely intangible. This makes it impossible for sensory-type shinobi to track users of this technique by their chakra. This technique is very useful when infiltrating enemy ranks. However, due to chakra suppression, one cannot use ninjutsu or genjutsu. Unlike other people, because of his connection to Ootsutsuki and his complete mastery of the technique, Sasuke can ignore these problems).
