In 46th year of Konoha, inside a quiet cabin, a flash of light appeared and a human figure materialized within the house.
"I finally made King Piccolo's defense break." Looking at the drop of blood in his hand obtained through painstaking effort, Chiaki Setsuna sighed with emotion.
He had transmigrated to the Naruto World for thirteen years already. When he had just realized he transmigrated to the Naruto World, he had envisioned many paths for his future.
There were routes involving researching and transplanting Kekkei Genkai, routes involving taking the Sannin as masters to practice Senjutsu, and at worst, just becoming a mediocre ninjutsu doctor.
However, reality quickly gave him a harsh wake-up call.
His chakra talent was quite good, but his ninjutsu talent was a complete mess. Similar to the future Rock Lee, he had almost no talent for ninjutsu and genjutsu, and he once faced the dilemma of being pressured to drop out.
Fortunately, Konoha at this time could still be considered the "beacon" of the ninja world. Considering that his parents were both Chunin who sacrificed their lives in the Second Great Ninja War and had meritorious service to Konoha, Hiruzen Sarutobi still kept him on after seeking Setsuna's opinion, trash talent or not.
In a sense, mediocrity remaining at the Ninja Academy actually carried risks.
This is because once a war broke out and entered a critical stage, academy students would also be sent to the battlefield.
The reason Setsuna insisted on staying was, of course, for taijutsu training.
No matter how mediocre an academy teacher's level was, they were still a Chunin, which was naturally better than him figuring things out behind closed doors.
Of course, the most crucial part was that the Myriad Worlds Pearl that brought him across was still there, and he could still transmigrate to other worlds. Even if he could not practice ninjutsu, he still had other paths to take.
It was just that considering he was too young back then, it would have been troublesome if he transmigrated to a world more dangerous than Naruto. Furthermore, the Myriad Worlds Pearl reminded him that after activating a transmigration, he had to stay in that world for at least a year before he could transmigrate back to his home world. Therefore, he lay low, waited, and patiently practiced taijutsu.
He trained according to the method Rock Lee used in the original work, discovering that his talent in taijutsu was quite good. Although he could not compare to those super geniuses, after eight years of bitter cultivation, he had also practiced to a level close to a Taijutsu Jonin.
A Taijutsu Jonin sounded very nice, but in this world of ninjutsu, pure taijutsu ninja were too easily targeted. Against things like genjutsu and poison techniques, he had almost no ability to resist.
Precisely because of this, although his strength had long surpassed most of his peers, he was happy to stay at the Ninja Academy as a habitual repeater. Moreover, he was not intentionally hiding his edge; who told him that he truly could not use the Three Body Technique.
Konoha currently did not have a specialized-talent system, and his lopsided specialization was not recognized by the mainstream.
However, as time gradually drew closer to the Third Great Ninja War, Setsuna knew that he could no longer wait. Once the war broke out and reached its most intense moment, the village would mostly likely still make him go to the battlefield even if he could not graduate.
Therefore, he chose to initiate his first transmigration. Then, the accident happened without any surprise.
After transmigrating, he found himself tens of thousands of meters in the air. Just as he was lamenting my life is over, an imposing divine dragon suddenly obscured the sky.
Could this be the Dragon Ball World? Setsuna had no time for astonishment or second thoughts, nor did he have time to ponder whether the language was mutually intelligible. He shouted at top speed, "Shenron, please grant me an Immortal Body!"
To Setsuna's surprise, the languages of the two worlds were actually mutually understandable, and his wish was fulfilled. Although he was smashed to smithereens, the power of the Immortal Body allowed him to recover quickly.
If he had a choice, he would of course have wished for a Saiyan bloodline to grind his combat power, but the reality was that he had to ensure his own survival first.
Moreover, the power of the Immortal Body also allowed him to push his body's potential to the limit using the most brutal methods for training. It was precisely this cruelty that earned him the appreciation of the Crane Hermit, allowing him to become a disciple under the Crane Hermit.
After mastering ki, the very first thing he learned was the Bukūjutsu. He did not want to repeat his previous experience, so learning flight had to be a priority.
The taijutsu foundation he built in Konoha was quite decent, and coupled with the Immortal Body allowing him to recklessly squeeze his physical potential for cultivation, in merely a year he overwhelmed Tien Shinhan in the 22nd World Martial Arts Tournament, yet still fell to Goku—who suddenly had a burst of potential mid-battle—and settled for runner-up.
Then, when he was preparing to find the Dragon Balls to obtain a powerful bloodline after the match ended, he happened to run into King Piccolo, who was also searching for the Dragon Balls after breaking his seal. He had to admit that even old and frail, King Piccolo was powerful to the point of despair; Setsuna was thrashed until he had almost no room to fight back.
Although he had an Immortal Body, there were simply too many methods that could restrict an Immortal Body. To put it simply, as long as King Piccolo dismembered him and buried him, he would meet the exact same fate as Hidan.
Therefore, the moment he first exposed the secret of his Immortal Body, Setsuna seized the split second of King Piccolo's shock, tried his absolute best to injure King Piccolo, and then returned to the Naruto World with that drop of blood at maximum speed.
Withdrawing his thoughts, Setsuna solemnly retrieved a small glass vial to collect the blood, and then took out a Capsule and tossed it to the ground. Hearing a light pop, a suitcase appeared before his eyes.
This was a Hoi-Poi Capsule he bought in the Dragon Ball World. Besides King Piccolo's blood, it also treasured Goku's hair—a backup plan he had considered long ago. The Myriad Worlds Pearl informed him that aside from Naruto World, which was bound as the main world, returning to any other world required going through the cooldown of three transmigrations.
Therefore, if he could not obtain the Saiyan bloodline by making a wish, he could also gain power by transplanting cells. Furthermore, this time he had also acquired a Namekian's blood.
"However, transplanting cells is not such a simple matter. It seems I must find a way to approach Orochimaru and learn his scientific technology of cell transplantation," Setsuna pondered inwardly, suddenly thinking of a question: Is my Immortal Body still there?
After all, it was only a wish made to Earth's Shenron; crossing universes to take effect was mostly impossible.
Thinking of this, Setsuna casually picked up the kunai in the room and thrust it toward the index finger of his left hand. With a crisp clack, the kunai snapped directly.
Setsuna shook his head slightly. The ki cultivation system evidently leaned toward the direction of low magic resistance and high physical defense. Goku could withstand gunfire right when he appeared, and after training under Master Roshi, he could even withstand artillery bombardment. Although part of it was due to the Saiyan physical body, it was enough to demonstrate the sheer strength of that system's physical defense.
Setsuna hardened his heart a bit, using his right hand to fire a Dodon Ray that pierced straight through his left index finger.
As if lacking any sense of pain, he watched expressionlessly as the wound healed at a speed visible to the naked eye, returning completely to normal in about a minute.
"Even though the Immortal Body was weakened, it still has some effect," Setsuna thought to himself.
If it were the original Immortal Body, this little injury would have healed instantly, but he was already very satisfied. With his physical defense combined with that recovery speed, very few people in the Naruto World should be able to kill him.
"What's more, I have Senzu Beans!" Setsuna looked toward the cloth bag inside the suitcase; the thirty Senzu Beans inside were his greatest source of confidence.
The Senzu Beans had not been squandered away by Yajirobe yet, which was how he managed to obtain so many from Korin.
As long as he was not killed in a single instant, he could rely on Senzu Beans to recover.
After putting the small glass vial into the suitcase, Setsuna retrieved four weighted bracelets from it.
These bracelets were weighted ones he specially crafted in the Dragon Ball World. Setsuna put the four bracelets onto his wrists and ankles respectively, and looked out at the already quiet night of Konoha: "Today's training isn't finished yet, time to go for a night run."
