"Nagi-kun, dinner's ready~"
A pleasant female voice came from the living room. To be honest, Uchiha Nagi was particularly unaccustomed to this situation: a young, beautiful girl staring at him every day with sparkling, amorous eyes.
Should he be a beast, or worse than a beast... Even more embarrassing was that the paper money he had prepared from the Naruto World had become useless in this world, not even comfortable for wiping his butt. Moreover, to reduce the weight and space of his storage scrolls, Uchiha Nagi hadn't exchanged any gold to store when he was fleeing.
Aside from the books he carried, he only had Exploding Tags, military rations pills, and kunai... However, considering that if he joined the Demon Slayer Corps, he wouldn't have to worry about living expenses, Uchiha Nagi remembered that although this world tried its best to conceal the existence of demons, it didn't prohibit the development of the Demon Slayer Corps. Clearly, the human high-ranking officials knew about it.
Furthermore, even ordinary members of the Demon Slayer Corps earned 200,000 yen a month, and Pillars were given as much as they needed, not to mention the vast support staff. This clearly indicated financial support from the government behind the scenes.
How much funding would such a complete system require?
Kagaya Ubuyashiki's ancestral family fortune was clearly not enough. Every generation of Ubuyashiki didn't live past thirty, and after eighteen, they were already sickly, with no energy to manage businesses.
Also, newspapers never reported on the Demon Slayer Corps, which could only be achieved with the help of high-ranking human officials.
And there were the annual selections of Demon Slayer Corps recruits from all over the country, with so many deaths... But those were too far off. What Uchiha Nagi wanted to do now was to quickly analyze the data comparison of his transplanted White Zetsu arm, then enhance his strength. Additionally, he wanted to learn this world's Breathing Technique.
If Uchiha Nagi was not mistaken, this world's Breathing Technique should be similar to Sage Art, which is natural energy... "Nagi-kun, try this~"
The girl, Kagome, placed a carefully cooked piece of meat into Uchiha Nagi's bowl.
"Thank you, Kagome." Uchiha Nagi wasn't pretentious; he picked it up and ate. He consumed almost eighty percent of the meal. The significant blood loss and Chakra recovery in his body required food to replenish nutrients.
"Hehe, Nagi-kun eats even more than me. When I was little, my nickname was 'Glutton,' and when I grew up, it was 'Big Sister Bucket.' If you don't mind, Nagi-kun can just call me 'Bucket,'" Kagome said, blinking her eyes.
"..."
After he had eaten his fill, Uchiha Nagi looked at Kagome, "Is there anything you want? I've always believed in equivalent exchange. You saved me once, so feel free to ask for anything you want."
The girl blinked, then suddenly blushed, not knowing what she had thought of. She quickly shook her head, "No, no, I don't want anything. Nagi-kun, you should focus on recovering first. I'm going to Doctor Tamayo's place to get some medicine."
"No need..."
"How can that be? Don't worry, I have money."
Before Uchiha Nagi could finish speaking, the girl dashed off in a flurry, her face already flushed to her ears. He had no idea what kind of inappropriate thoughts were running through her mind... Uchiha Nagi said helplessly, "Sigh, what I meant to say was that some of my Chakra has recovered, and I can treat my external injuries myself."
With that, Uchiha Nagi raised his right hand, and green-glowing Medical Ninjutsu emanated from it as he began to treat his left arm.
However, while it could heal, it couldn't regenerate severed limbs, because Medical Ninjutsu essentially caused human cells to divide again on their own.
He found a mirror, and Uchiha Nagi slowly closed his eyes. When he opened them again, three tomoe appeared, then rapidly spun, eventually accelerating and merging together, forming a Mangekyo Sharingan.
"Why does it look a bit like a plum blossom?" It was a Mangekyo pattern similar to a plum blossom, with a round center and petals around it. Although his left eye couldn't temporarily use mind transfer, if it was only used for visual observation and not for ocular Ninjutsu, the consumption of ocular power wasn't significant.
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 premonition that the ability would definitely not be bad, but what else did he want in his mental image at the time, besides escaping?
"Earth Release: Temporary Underground Base Technique~"
Then, before Kagome arrived, Uchiha Nagi used Earth Release to create a small underground room, similar to Yamato's Wood Release house technique.
The difference was that the temporary underground room made with Earth Release was not stable and needed to be reinforced with Ninjutsu every day.
Uchiha Nagi took out some medical equipment from his storage scroll, as well as 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 returning to the Naruto World for revenge in the future or for surviving safely here, increasing his strength was an urgent matter.
"One hand is indeed inconvenient. Shadow Clone Technique." Uchiha Nagi formed a hand sign with one hand and created two clones.
Hand signs merely stabilize Chakra output and the formation of the technique; they can be done with one or two hands. If one's control is strong, they might even be able to perform techniques without signs.
So, Uchiha Nagi began to extract white zetsu cells in the basement and conduct clinical trials with his blood. Although his past life memories told him that White Zetsu's cells were not as overbearing as the First Hokage's, perfect fusion was not that easy either.
"Nagi-kun, where did you go~ Nagi-kun?"
Hearing Kagome calling him from outside, Uchiha Nagi stopped his experiment, put his things into the storage scroll, and walked out of the temporary Earth Release underground room.
"I'm here." Uchiha Nagi walked out of the basement and responded.
"Oh, 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 previous matter out of her mind. "Nagi-kun, I've got the medicine. Come inside, I'll change your dressing."
"No need, I'll do it myself..."
"No, you can't. One hand is inconvenient. I'll change it for you."
"..."
And so, Uchiha Nagi took off his shirt and sat in the room, letting the girl bandage and change his dressing. Besides the arm injury, he also had kunai wounds on his body, but those were minor injuries not in vital areas.
While Kagome was changing his dressing, her face was constantly red, and she occasionally touched his muscles, not knowing what she was thinking.
Considering that the other person wasn't an auntie or a man, Uchiha Nagi endured it... That night, after nightfall, Kagome helped Uchiha Nagi make his bed. She then seemed to think of something, stood dazed for a while, and when Uchiha Nagi called her, she actually covered her face, shrieked, and ran out.
Uchiha Nagi: "..."
I didn't do anything—
