"Hush…" Kagaya Ubuyashiki said, "He once sent people to hunt Tanjiro, which is enough to prove that Tanjiro and his sister attract him in some way."
"Although his reason was to silence them, this is the first time I've caught Muzan Kibutsuji's tail. I'm afraid there's something about Tanjiro and Nezuko that we don't know about." Obviously, this information was given to him by Tamayo.
"Understood, Master, but humans can be spared; demons cannot. This has been the Demon Slayer Corps' fighting creed until now. So many people have sacrificed themselves for this; I cannot agree."
After speaking, Wind Pillar Sanemi Shinazugawa pulled out his nichirin blade and cut a wound on his hand. His blood was rare, with a very strong attraction to demons.
"Let me prove the ugliness of demons."
"You don't need to prove it—" Uchiha Nagi's voice came from the side.
"What did you say?" Wind Pillar Sanemi Shinazugawa looked at Uchiha Nagi menacingly; he still hadn't settled the score from earlier.
"I am the finest among rare blood types. I am even more attractive than you. Nezuko hasn't attacked me for so many days; I am the best proof," Uchiha Nagi said calmly.
The white zetsu cells, combined with the Uchiha Clan's cells, made him a highly sought-after delicacy in this world for many demons, like a ginseng that could increase a thousand years of power if consumed.
"What a joke! You say your blood is rarer than mine? Who can prove it?" Sanemi Shinazugawa roared.
"I can prove it. On the first day Mr. Nagi appeared, I received a letter from a friend. He indeed has rarer blood than you," Kagaya Ubuyashiki said with a smile.
"I can offer something of equal value in exchange to vouch for Nezuko," Uchiha Nagi said calmly.
"Exchange? Do you want to use money? Who lacks money?" Wind Pillar Sanemi Shinazugawa scoffed.
Most people here had no concept of money. Apart from their nichirin blades, they basically needed nothing else. Money was only used for daily meals and lodging.
Moreover, a Pillar's monthly salary was 200,000, and they could take more if needed...
"I'll exchange Medical Ninjutsu." Uchiha Nagi activated a green glowing Chakra with one hand. He walked up to Sanemi Shinazugawa and motioned for him to extend his hand.
Wind Pillar Sanemi Shinazugawa frowned, but Kagaya Ubuyashiki, after hearing his daughter whisper, nodded.
"Sanemi, extend your hand and let Mr. Nagi try. I believe that as a human, he won't harm you."
Finally, Sanemi Shinazugawa reluctantly extended his hand. Uchiha Nagi covered his wound with Mystical Palm Technique, and a miraculous scene unfolded: the wound began to stop bleeding and then slowly healed. In a short while, under everyone's astonished gaze, Sanemi Shinazugawa's wound completely disappeared, and not only that, but there wasn't even a scar left.
"Sugoi... Not even a scar left! Mr. Shinazugawa is blessed; all his wounds can be healed!" Shinobu Kocho exclaimed.
"Damn it! Scars are a man's pride! Who wants to heal them!" Sanemi Shinazugawa roared in anger.
Many people fell silent. They all knew that this 'Medical Ninjutsu,' seemingly simple, had a huge effect in battle.
With such a miraculous thing, who knew how many casualties could be reduced.
"At the same time, I promised Miss Tamayo to temporarily join the Demon Slayer Corps. In exchange, after joining the Demon Slayer Corps, I am willing to trade my Ninjutsu for the Breathing Technique." Uchiha Nagi finished speaking and formed a hand seal.
Bang!
Several Uchiha Nagis appeared before everyone's dumbfounded eyes. It was the Shadow Clone Technique. To demonstrate its effect, several Shadow Clones took turns carrying Tanjiro as a model.
Tanjiro: "..." How amazing... If I could do this, my strength would probably multiply several times, right?
Shinobu Kocho thought, as the only Pillar who fought with poison, the Shadow Clone would be like adding wings to a tiger for her, perfectly tailored.
Kagaya Ubuyashiki leaned down and asked his daughter about something, then nodded.
"Mr. Nagi, having Giyu Tomioka and Mr. Sakonji Urokodaki vouch for Nezuko is already enough. However, as you said, the Demon Slayer Corps desperately needs these things you've shown. They can enhance the children's strength a little and reduce casualties a little. Please forgive my shamelessness in accepting them."
He paused, then Kagaya Ubuyashiki said, "As for the Breathing Technique, anyone who joins the Demon Slayer Corps, even if they're not in the Demon Slayer Corps, as long as they are willing to fight Muzan Kibutsuji, we are willing to teach it. After all, the more strength humanity has, the greater the chance of eliminating him."
"Then, if there are no objections, Mr. Nagi will be the Demon Slayer Corps' newly promoted Pillar."
"What? A Pillar?"
"I disagree! Why is he a Pillar as soon as he arrives? Just for a few Ninjutsu?"
Several Pillars were quite displeased.
"Exactly," Sanemi Shinazugawa said, "Every Pillar here has a record of slaying many demons, even members of the Twelve Kizuki. What does he have?"
At this moment, a leisurely voice came: it was Giyu Tomioka.
"He just defeated you with genjutsu..."
Sanemi Shinazugawa's mouth twitched.
Shinobu Kocho also covered her mouth and chuckled, "Mr. Nagi also slew one of the Twelve Kizuki named Rui last night. He was Lower Rank Five, you know." Sanemi Shinazugawa was completely petrified and said no more...
After dawn, Rui's body naturally turned to ash. As for his soul, it was unknown if the Shinigami of this world would come to snatch him from Uchiha Nagi, who had sealed him in the Sword of Totsuka.
Kagaya Ubuyashiki smiled and said, "Then let's officially welcome Uchiha Nagi into our Demon Slayer Corps family. Afterwards, someone will customize a dedicated nichirin blade and attire for you. I am not feeling well, so I will take my leave. Please, everyone, take some time to socialize."
"Tanjiro, please give my regards to Miss Tamayo..."
Tanjiro was shocked to hear this. How did the Master know Tamayo?
"Oh, oh, another Pillar has joined! This is good news!" The Flame Pillar, the elder brother, said happily.
"I'm interested in that Shadow Clone Technique. I wonder if I can learn it..." Muichiro, the Mist Pillar, who was drawing circles on the ground with his small hands, said blankly.
Immediately after, Tanjiro and his sister were taken back to Shinobu Kocho's residence by the logistics staff, as that was the Demon Slayer Corps' medical base.
Uchiha Nagi didn't mind. He directly stated that Ninjutsu required Chakra as its fundamental energy to be performed, and also explained the basic knowledge of how to refine Chakra.
"Hmm... This is difficult to understand, I don't get it at all..." The Flame Pillar, the elder brother, said directly.
"It seems it won't be so easy to learn," the Stone Pillar also nodded.
"Many Ninjutsu I know, such as Water Release, Fire Release, Earth Release, Wind Release, Medical Ninjutsu, etc., all require Chakra as their foundation. You can come to me to learn after successfully refining Chakra."
After Uchiha Nagi had a few people on the spot touch and feel the difference between Chakra energy and Breathing Technique, Uchiha Nagi and Shinobu Kocho left. He was going to check on the injured individuals.
