In a cave, Uchiha Nagi and Kimimaro settled down.
Uchiha Nagi took out some dry rations and water, handed them to Kimimaro, and at the same time took out some test tubes and began to mix colors.
"Sir, what are you going to do?" Little Kimimaro asked curiously.
"Your white hair is too conspicuous; I need to dye it black so we can easily avoid detection. After I finish the transaction with Orochimaro, I'll take you out of the Land of Water to see the vast world outside."
"Oh~"
"By the way, you don't have to call me 'Sir' anymore. I don't really like people calling me that," Uchiha Nagi said.
Although 'Sir' doesn't have any special meaning in the Ninja World, it's just a sign of respect, Uchiha Nagi just didn't like it; it felt too much like a clear class distinction.
Kimimaro scratched his head, puzzled, "Then what should I call you?"
Uchiha Nagi thought for a moment. Big Brother? Adoptive Father? Forget it. "You can call me Teacher from now on."
Uchiha Nagi felt that being a Big Brother, Adoptive Father, or Sir, which implies a superior-subordinate relationship, was not as good as simply having a student-teacher relationship.
There's a saying: 'A teacher for a day is a father for life.' Orochimaro took Kimimaro as a vessel, but who knew if he had any affection for him? One must remember that he couldn't bring himself to kill Anko, who tried to assassinate her teacher, let alone Kimimaro, who was loyal and raised by him from a young boy.
In the original timeline, Orochimaro was respectfully called 'Sir' by Kimimaro, which seemed like a superior-subordinate relationship, but in reality, it was more akin to a master-disciple bond. When Kimimaro died, Orochimaro also showed a hint of unusual emotion, though it was very deeply hidden.
[Wait, Teacher...]
Uchiha Nagi suddenly remembered that people in the Ninja World had a habit of killing their teachers: Orochimaro killed the Third Hokage, Nagato killed Jiraiya, and Sasuke killed Orochimaro.
Shaking his head vigorously, Kimimaro shouldn't be that kind of person. If he instilled in him the concept of respecting his teacher, it shouldn't happen, right? "Kimimaro, what Ninjutsu do you know right now?" Uchiha Nagi asked.
"What I know? Hmm, I only know a part of the Shikotsumyaku from my clan: Ten-Finger Drilling Bullets, and this bone blade, as well as creating Chakra bones beneath my skin. That's all..." Kimimaro thought for a moment and replied.
He was still a young boy, and his body hadn't fully developed. Knowing this much was already impressive. Simply creating hard Chakra bones beneath his skin already made him a human tank.
As for Ten-Finger Drilling Bullets, due to his age, its power was still very small, similar to throwing a kunai.
"Don't you know any other Ninjutsu, like the Three-Body Technique or elemental Ninjutsu?" Uchiha Nagi asked.
"Sorry, Teacher, I don't. The clan leader never taught me..." Kimimaro scratched his head apologetically.
"From today onwards, unless your life is in danger, do not use the power of the Shikotsumyaku. Later, I will teach you the Three-Body Technique and Ninjutsu. Remember, do not use the power of the Shikotsumyaku unless your life is in danger," Uchiha Nagi said earnestly to Kimimaro.
The power of Shikotsumyaku is very strong. When Kimimaro was with Orochimaro, because this power was too strong, he looked down on other Ninjutsu, which led to him becoming powerful later on, even personally killing Gaara's father, the Kazekage. The result was a bloodline disease, meaning the genetic disease of Shikotsumyaku worsened, and then he was gone... Uchiha Nagi hoped Kimimaro would reduce the development of Shikotsumyaku, thereby delaying the onset of his body's bloodline disease, or see if it could be cured.
"Uh, yes, Teacher, but why don't you want me to use it? The bloodline ability is very strong and useful," Kimimaro asked curiously.
"Over-developing it will induce the outbreak of the genetic disease in your body. I will teach you other things later. In short, do not use Shikotsumyaku unless you are in life-threatening danger." "Oh."
Kimimaro, at present, was a polite young boy. Although he didn't understand what a genetic disease was, he knew that his Teacher cared about him, and he immediately felt a warmth in his heart.
Kimimaro happily took the dry rations and heated them over the bonfire, and he even proactively laid out the bedroll, clearly in a very good mood.
After they had eaten and drunk their fill, Uchiha Nagi picked up the dye and colored his hair black, making it less conspicuous.
"Teacher, the bedroll is laid out."
Uchiha Nagi nodded, "I don't need to rest tonight; this is for you to sleep on."
Kimimaro was stunned, "Ah, for me? Then you..."
Uchiha Nagi said, "You saw the person I fought. Before we leave the Land of Water, we must remain vigilant. Don't worry about me; Ninja can go two or three days without sleep."
Of course, it wasn't really no sleep; he could just send out two Shadow Clones to stand guard while he slept. However, after dispelling them, the fatigue from standing guard would still be transmitted to the main body, but in comparison, between fatigue and recovery, the recovery ratio was always a bit larger.
His body still got rest and could recover a lot of energy.
In the cave, the bonfire illuminated Kimimaro's face~
Kimimaro lay on the bedroll for only ten minutes before falling asleep with a happy smile. Children of his age tend to get tired easily.
"It doesn't seem that hard after all," Uchiha Nagi muttered to himself, looking at Kimimaro.
Uchiha Nagi had no confidence in abducting little Kimimaro, after all, he wasn't a successor to the Will of Fire [brainwashing expert]. But the result was surprisingly smooth. Uchiha Nagi scratched his head. Could it be that orphans are more likely to trust strangers?
Not only Uchiha Nagi had a sleepless night, but so did Orochimaro. Uchiha Nagi was worried about sneak attacks from the Hidden Mist Anbu and Orochimaro, while Orochimaro was shocked by the small smear of ghost (ghost) blood he had obtained.
He discovered that it was a very peculiar type of cell. If the First Hokage's cells were like plants, with a huge rejection from the human body, and even more aggressive than cancer, then this type of cell was a mutated human cancer cell.
As is well known, human cells have a limited number of divisions, roughly ten times in a lifetime.
As people age, cell division becomes slower and slower, vitality decreases, until cells reach the end of their life, and thus the various functions of the elderly also begin to show problems in old age.
However, mutated human cells, cancer cells, have no such limitations and can divide indefinitely. Many people say that the secret to human longevity may be hidden in cancer cells... because once the human body is no longer troubled by the number of cell divisions, it will achieve longevity.
From the blood obtained from Uchiha Nagi, Orochimaro discovered that it actually had the same characteristics as cancer cells, with the possibility of infinite division. However, some subsequent tests by Orochimaro made him frown, because this type of cell was most interested in human hemoglobin as its nutrient.
In other words, its food might be human blood... and the effect of absorption, division, and reproduction after absorbing the blood of other animals, such as snake blood or bird blood, was very low.
[PS, Death Goddess, HeLa cells. Those interested can look it up. This woman died but lives on permanently on Earth, having lived for over 150 years, she is humanity's first immortal.]
