"Nagi-kun, dinner is ready~"
A pleasant female voice called from the living room. To be honest, Uchiha Nagi was particularly unaccustomed to this kind of situation: a beautiful young girl staring at him all day with love-struck eyes.
Was he supposed to act like a beast, or worse than a beast...?
Even more awkwardly, the paper money from the Naruto world he had prepared was now useless paper in this world—not even comfortable enough to wipe his rear with. And to reduce the weight and space of his storage scroll, Uchiha Nagi hadn't exchanged any gold for storage when he fled.
Apart from the books he carried, all he had were explosive tags, soldier pills, and kunai...
However, considering that if he joined the Demon Slayer Corps, he wouldn't have to worry about his livelihood, Uchiha Nagi remembered that although this world did its best to conceal the existence of demons, it didn't prohibit the development of the Demon Slayer Corps. Clearly, the human higher-ups were aware.
Moreover, even ordinary members of the Demon Slayer Corps received a monthly salary of 200,000, and Hashira-level members were given as much as they needed. Not to mention the vast logistical support staff. It was evident that the government was secretly providing financial backing.
How much funding would such a complete system require?
The Ubuyashiki family's ancestral wealth was clearly not enough. Every generation of Ubuyashiki lived no longer than thirty years, and after eighteen, they were sickly, lacking the energy to manage businesses.
Furthermore, newspapers never reported on Demon Slayer Corps matters, something only achievable with help from the human higher-ups.
And then there were the numerous deaths each year from the Demon Slayer Corps' seed selection process, drawing candidates from all over the country...
But those were distant concerns. What Uchiha Nagi wanted to do now was to quickly complete the data comparison for transplanting the White Zetsu arm, then enhance his own strength. Additionally, he wanted to learn this world's Breathing Styles.
If Uchiha Nagi wasn't mistaken, the Breathing Styles of this world should be similar to Sage Jutsu, that is, natural energy...
"Nagi-kun, try this~" Kagome placed a carefully cooked piece of meat into Uchiha Nagi's bowl.
"Thank you, Kagome." Uchiha Nagi wasn't one for pretense; he picked it up and ate. Almost eighty percent of the meal ended up in his stomach. Significant blood loss and chakra recovery both required food intake for nourishment.
"Heehee, Nagi-kun eats even more than I do! When I was little, my nickname was 'Rice Bucket.' When I grew up, they called me 'Sister Bucket.' If you don't mind, Nagi-kun, you can just call me 'Bucket'." Kagome said, blinking her eyes.
"..."
After he had eaten and drunk his fill, Uchiha Nagi looked at Kagome. "Is there anything you want? I've always believed in equivalent exchange. You saved my life once, so you can ask for anything you desire."
The girl blinked, her face suddenly blushing for some unknown reason. She quickly shook her head. "No, no, there's nothing I want. Nagi-kun, you should focus on getting better first. I'll go get medicine from Doctor Tamayo."
"There's no need..."
"How can that be? Don't worry, I have money."
Before Uchiha Nagi could finish, the girl rushed off like a whirlwind, her face red to the tips of her ears. Who knew what kind of "harmonious" thoughts were running through her mind...
Uchiha Nagi sighed helplessly. "Sigh, what I meant to say was, I've recovered some of my chakra and can treat my external injuries myself."
With that, Uchiha Nagi raised his right hand, which emitted the green glow of Medical Ninjutsu, and began to treat his left arm.
However, while he could heal it, he couldn't regenerate a severed limb, because Medical Ninjutsu essentially just stimulated the body's cells to divide again.
Finding a mirror, Uchiha Nagi slowly closed his eyes. When he opened them again, the three tomoe of his Sharingan appeared, then spun rapidly, eventually accelerating and merging together. A Mangekyo Sharingan pattern emerged.
"Why does it look a bit like a plum blossom?" The Mangekyo pattern resembled a plum blossom, with a round center and surrounding petals.
Although his left eye couldn't use Mind Teleporter for the time being, just using it for visual observation without activating dojutsu wouldn't consume much of its power.
His right eye... he would try it in a couple of days, when his body's chakra recovered to ninety percent, to see what its ability was. Uchiha Nagi had a hunch that the ability wouldn't be weak. But besides escape, what else had he desired in his heart's reflection at that moment?
"Earth Style: Temporary Underground Base Jutsu~"
Then, before Kagome returned, Uchiha Nagi used Earth Style to create a small underground room, a technique similar to Yamato's Wood Style houses. The difference was that an Earth Style temporary basement wasn't stable and needed to be reinforced with ninjutsu daily.
Uchiha Nagi took out some medical equipment from his storage scroll, along with a section of a White Zetsu arm...
Although this world was safe, it was only during the day. Nights were not one hundred percent safe. Whether it was for future revenge in the Naruto world or for surviving safely here, improving his strength was an urgent matter.
"One hand is indeed inconvenient. Shadow Clone Jutsu." Uchiha Nagi performed a one-handed seal and created two clones.
Hand seals were merely for stabilizing chakra output and jutsu formation; they could be done with one or two hands. With strong enough control, one might not even need seals.
Thus, Uchiha Nagi began to extract White Zetsu cells in the basement and conduct clinical trials with his own blood. Although his past life's memories told him that White Zetsu cells weren't as domineering as the First Hokage's, perfect fusion wouldn't be that easy.
"Nagi-kun, where did you go~? Nagi-kun?"
Hearing Kagome calling for him outside, Uchiha Nagi stopped his experiment, stored everything back into the storage scroll, and walked out of the temporary Earth Style basement.
"I'm here," Uchiha Nagi responded as he emerged.
"Huh? Nagi-kun, you're here! When did my garden get a basement?" Kagome asked, looking puzzled.
"I just made it. I needed to do some experiments, and it wasn't convenient in the house."
"Oh." The lively and cheerful girl immediately put the matter out of her mind. "Nagi-kun, I brought the medicine. Come inside, and I'll change your dressing for you."
"No need, I can do it myse—"
"No way, it's inconvenient for you with one hand. I'll do it."
"..."
And so, Uchiha Nagi took off his shirt and sat in the room while the girl bandaged and changed his dressings. Besides the injury on his arm, he also had kunai wounds on his body, though those were minor and not in vital areas.
While Kagome was changing the dressings, her face was constantly red, and she would occasionally touch his muscles, lost in some thought.
Seeing as she wasn't an old lady or a man, Uchiha Nagi endured it...
That night, after Kagome had helped Uchiha Nagi make his bed, she seemed to think of something, stared blankly for a moment, and then, after being snapped out of it by Nagi, she covered her face, shrieked, and ran out.
Uchiha Nagi: "..." I didn't do anything—
