Chapter 5: Training
Beside the lake, Kiyoshi sat quietly on the ground, a large scroll spread out before him. It was the bloodline scroll related to the Shikotsumyaku that he had just summoned using the Summoning Technique.
"Ten Finger Drilling Bullets, that must be the move Father said I unconsciously used that day! Mobilize Chakra to the finger meridians, manipulate osteoclasts to shoot the finger bones of all ten fingers as bullets, and then manipulate osteoblasts to control the calcium concentration and accelerate the formation of new finger bones. Under the power of the Shikotsumyaku, finger bones can grow infinitely. Even if all the finger bones are fired, they can be regenerated."
"I see." The scroll explained the technique and its corresponding usage and training methods very clearly. Kiyoshi slowly mobilized the Chakra within his body according to the description, spreading his fingers and aiming his hands at the lake in front of him.
"Shikotsumyaku: Ten Finger Drilling Bullets!"
White finger bones broke through his fingertips, quickly detached, and shot towards the front.
"Splash!"
A large splash of water erupted where the lake surface was hit. "So strong!" Kiyoshi exclaimed, "And it seems the power of this move is also related to the intensity of Chakra output. Moreover, if controlled well, it can even be fired continuously. Let's try a higher power output."
Kiyoshi mobilized nearly half of his total Chakra, pouring it all into his fingertips according to the operating route described in the scroll, and used the Ten Finger Drilling Bullets again.
"Bang!"
Accompanied by an even louder explosion, the lake water was blasted more than three meters high.
Kiyoshi stared dumbfounded at the giant waves that had been stirred up on the lake.
"What powerful destructive force!" he murmured.
"Yosh, then let's first learn to master the Ten Finger Drilling Bullets, so that I can control the power and master continuous firing!"
Genji and Kiyoshi, who had not yet awakened his past life's memories at that time, did not understand, and it could be said that no one in the current ninja world understood, that the bloodline Kiyoshi awakened was not the ordinary Kekkei Genkai of the Kaguya clan, but that during the awakening process, atavism had occurred, and he had initially possessed some of the bloodline characteristics of his ancestor, Kaguya Otsutsuki.
This was the Otsutsuki bloodline, whose level was far higher than that of the Kaguya clan's bloodline. Although it was just a nascent, very thin Otsutsuki bloodline, it already possessed some of the characteristics of the Otsutsuki. Therefore, in terms of Chakra manipulation and learning various techniques, Kiyoshi's talent was undoubtedly strong.
In just two days, Kiyoshi had mastered the Ten Finger Drilling Bullets very skillfully. He could freely control the power and firing speed, and he could switch between single shots and continuous firing at will.
Kiyoshi could even achieve more precise control than his Kaguya clan predecessors. He could control the number of bone bullets and could fire bone bullets individually from one or several fingers.
In this way, for the next year and a half, Kiyoshi came to the lakeside far from the village every day to train his Chakra and bloodline.
Time came to Mist Village Year 27.
The 8-year-old Kiyoshi's height had also grown to 140cm under the effect of his bloodline awakening, and his physique had greatly improved.
Although his appearance was still thin and weak, his strength was hidden deep within his body, not to be underestimated. Every bone in his body exuded power under the effect of the Shikotsumyaku, like a sturdy pine tree in the mountains, resilient and powerful.
Day after day of training, coupled with the effect of bloodline awakening, had brought Kiyoshi's Chakra reserves to the level of an elite Chūnin. Although Kiyoshi had not fought other ninjas due to his exile, his combat power was likely around that of a Chūnin.
(He is currently incomparable to a certain white-haired boy who graduated at 5 and became a Chūnin at 6. The living environment is too harsh, and the protagonist awakened too late. Although his talent is good, he started too late.)
Beside the lake, a boy was dancing gracefully, his feet stepping on mysterious and profound steps. His body moved with the wind, like a free bird, as light as the wind, as free as the sunlight. Every turn and every leap felt incredibly light.
Looking closely, the dance was also full of power and tension. Every movement seemed to be accumulating energy. The dance steps were as smooth as flowing water, but they contained endless killing intent, making people dare not be careless in the slightest.
The boy was Kiyoshi, and these dance steps were the secret attacking methods of the Kaguya clan's bloodline, Shikotsumyaku.
In a year and a half, Kiyoshi, with his extraordinary talent, had mastered most of the Shikotsumyaku techniques.
The four techniques – Dance of the Willow, Dance of the Camellia, Dance of the Larch, and Dance of the Clematis – had all been mastered. Although the ultimate technique, Dance of the Seedling Fern, could not be used yet due to his current Chakra limitations, the release method was already deeply ingrained in his mind.
As for the two forbidden techniques inscribed at the end of the bloodline scroll, Shikotsumyaku: Blood Burning Technique, and Shikotsumyaku: Ash Bones Technique, which gathers all the body's Chakra and life force in a single strike in the blood-burning state, Kiyoshi had also fully mastered them as trump cards for desperate situations.
-----------------
**Shikotsumyaku: Dance of the Willow:** Without fixed forms, like willow catkins moving with the wind, it diffuses the enemy's attacks and uses a series of attacks with gentle taijutsu without any superfluous movements, combined with bones.
**Shikotsumyaku: Dance of the Camellia:** Extracts bone swords from both arms as weapons, combined with precise and flexible taijutsu to perform multiple consecutive attacks.
**Shikotsumyaku: Dance of the Larch:** Uses the bloodline limit to grow dozens of bones from the body. In close combat, it provides high defense while being able to strike enemies. The greater the power of the enemy's taijutsu or rushing attack, the stronger the counterattack effect, causing serious damage to the enemy.
**Shikotsumyaku: Dance of the Clematis:** Divided into two stages, Vine and Flower. It makes the spine like a whip to attack and restrain the enemy. After sealing the enemy's movements, it forms the hardest bone on the outside of both hands as a spear to attack, combining control and damage with extremely powerful force.
**Shikotsumyaku: Dance of the Seedling Fern:** Outputs a huge amount of Chakra, causing sharp bones to grow successively from the ground to attack the opponent. The scale of the bones depends on the size of the Chakra, and the bones basically cover the entire ground, like a forest of white bones. It is a terrifying technique that attacks the enemy comprehensively and is difficult to defend against. Even if the enemy cannot be defeated with bone swords, the user can quickly move and attack throughout the growing bone forest.
**Shikotsumyaku: Blood Burning Technique:** A forbidden technique that acts on oneself, burning one's own bloodline and transforming it into extremely strong energy to amplify one's own techniques. During the technique's effect, it can allow an elite Jōnin to gain power comparable to a Kage. After the technique's effect ends, the user's strength will greatly decline due to the burning of their bloodline.
**Shikotsumyaku: Ash Bones Technique:** Derived from Kaguya Otsutsuki's All-Killing Ash Bones, it is a degraded skill, but it still possesses the characteristic of annihilation. It is a life-risking technique engraved in the Kaguya clan's bloodline, burning all the power of the bloodline, causing the bloodline to briefly align with Kaguya, condensing all the body's Chakra and life force into a gray bone spur. If an enemy hit by it does not have special life-saving techniques, they will surely die. Similarly, it is a technique that will surely lead to the user's death after use.
(The Uchiha have Izanagi. During the Warring States period, the Kaguya clan, as descendants of Hamura, could go toe-to-toe with the Uchiha. It should be reasonable for them to have a weakened version of All-Killing Ash Bones.)
