In Uchiha Nagi's view, Genya's physique, which allowed him to eat demons, was incredibly valuable.
If he could analyze it, he could clone more white zetsu cells in the future, then directly consume them to further complete the Uchiha's genetic makeup.
Alternatively, he could trade with Orochimaru for First Hokage's cells.
Perhaps this genetic completion could lead to an atavistic phenomenon, specifically the Sage of Six Paths' genes.
Atavism is unpredictable; there's a branch family of the Hyuga on the moon whose genes exhibited atavism.
After transplanting a pair of pure Byakugan, he instantly transformed into a Tenseigan user, completely outclassing Naruto in Sage Mode with Nine-Tailed Chakra.
If not for plot armor...
Uchiha Nagi arrived at the Butterfly Mansion. Due to his research, he needed various equipment and many medicines, so he resided at the Butterfly Mansion whenever he didn't have special missions.
Uchiha Nagi deftly packed his tools, including a portion of Exploding Tags.
These were self-made after he arrived in this world, by having the Demon Slayer Corps purchase materials.
Because others couldn't use Chakra, the quantity he could make was a bit small and laborious.
Uchiha Nagi thought that as long as it was enough, it would be fine; he could just buy them directly when he returned to the Ninja World.
His body was undergoing secondary development, and by the time he was ready to return to the Naruto World, he might have reached ten cards of Chakra.
Ten cards, of course, couldn't compare to monsters like Naruto Uzumaki and Nagato, but compared to other Kage-level ninja, it was sufficient.
However, the winner in a battle of strength isn't solely determined by the amount of Chakra.
Tailed Beasts have much more Chakra than humans, yet they can still be defeated by weaker humans.
Naruto's Chakra was many times that of Kakashi, but before he learned Sage Mode with Nine-Tailed Chakra, he still couldn't defeat Kakashi.
"A demon that might possess precognitive abilities, or extremely powerful reconnaissance capabilities~" Uchiha Nagi frowned as he looked at the intelligence report delivered by the logistics staff.
The report stated, just as Kagaya Ubuyashiki had mentioned, that initially, several low-ranking Demon Slayer Corps members investigated missing persons, and eventually, those members disappeared.
Later, two Kage-level members led a team to investigate, but nothing happened.
As soon as the Kage-level members left, more people went missing.
The opponent seemed to be employing guerrilla tactics.
Then, when Giyu Tomioka went to investigate alone, no one went missing...
"Nagi-kun, are you going on a mission?" a pleasant female voice asked; it was Shinobu Kocho.
"Yes, it's a rather tricky mission.
The opponent might not be very strong, but they are exceptionally cunning, so Mr. Ubuyashiki believes only I can handle it," Uchiha Nagi nodded.
"Here are some healing medicines and some antidotes.
Please be careful; some demons possess venomous properties, Nagi-kun, please return safely," Shinobu Kocho handed him a small package containing many small medicine jars and such.
"Understood, thank you," Uchiha Nagi paused, "You be careful too.
There's no need to rush to avenge your sister; I'll help you when the time comes."
Uchiha Nagi remembered that Shinobu Kocho, in her quest for revenge, had transformed herself into a poisonous person, ultimately feeding herself to her enemy.
The Upper Rank Two demon who consumed her was successfully poisoned to death...
To avenge her sister, she perished with her enemy, a girl with a tragic fate.
Now that he knew, Uchiha Nagi didn't mind changing her tragic end.
Shinobu Kocho was stunned when she heard this, and by the time she reacted, Uchiha Nagi had already left.
Not far away, around a corner, three small figures huddled together, secretly whispering.
"Sister, why did he say he would help Sister Shinobu get revenge?!"
A small loli's head peeked out from the corner.
"Silly Kojie, of course, it's because one person can't defeat an Upper Rank demon; it takes two people to win."
"Little Cheng is the silly one; it's obvious that handsome uncle likes Sister Shinobu Kocho~"
"You're the silly one; he's not old at all, he's a big brother, okay~"
The three little lolis from the Butterfly Mansion were blushing, their ears red, chirping and arguing—
"Oh my~ So you were just loitering here.
It seems you've been too idle lately, haven't you?
Shall I add some special training for you tomorrow~" Shinobu Kocho's gentle voice came from behind the three little lolis.
"Ah~ I still have herbs to dry."
"The medicine in the stove is almost dry."
"We're leaving now~~" +3
Watching the three little girls flee in a hurry, Shinobu Kocho covered her mouth and chuckled, seemingly in a very good mood.
Under the sunlight, a faint blush appeared on her cheeks...
Uchiha Nagi arrived at the train station and took a train.
Since this world had such convenient transportation, why not use it?
This time, no special incidents occurred on the train.
Uchiha Nagi safely reached his destination, a place called Hakuba Town, along the way.
After getting off the train, the two accompanying Kage-level members introduced Uchiha Nagi to some local rumors.
This was because local myths often arose from ignorant villagers being enslaved by demons.
It was said that several hundred years ago, an injured white horse appeared here and was rescued by a monk.
To repay his kindness, the white horse transformed this place into a prosperous area, hence the name Hakuba Town.
However, for some unknown reason about a decade ago, the fertile soil of this place angered the gods, who brought down disaster.
Crops yielded nothing, floods raged, followed by droughts and then locust plagues, leaving only one in ten of the town's inhabitants.
Finally, a monk living in the temple sacrificed his life to the gods, finally earning forgiveness, and thus the town's people survived.
"That's how it is; later, the townspeople built a temple in memory of that monk..."
Uchiha Nagi nodded, "Tonight, you are free to move around.
I've tampered with this scroll; open it if you encounter danger."
The Kage-level team member nodded.
His name was Heiji, and the other was Ono.
Uchiha Nagi had specifically requested this mission because he felt that the Kage-level Demon Slayer Corps members were likely being avoided by the opponent, which was why they were hiding.
If there was only one member below Kage-level, the opponent would likely show themselves.
Demons have diverse tastes; some prefer children, some prefer young girls, while others prefer physically strong humans, such as Demon Slayer Corps members, whose bodies are far stronger than ordinary people due to long-term training with Breathing Techniques.
Tonight, the two of them would be bait, while Uchiha Nagi would hide in the shadows, waiting for the opponent to show their hand—
Soon, after night fell, every household in the town closed their doors, as if some great terror appeared in the night.
Even the electric lights in the houses were extinguished, indicating that the recent disappearances had cast a very large psychological shadow on the town's residents.
Even the police were helpless; they either left the small town or chose to silently endure.
Although the town had many people and officials tried hard to conceal the news, with a person disappearing every one or two days, over time, rumors spread everywhere.
