"Zenitsu, I heard Shinobu Kocho say that you defeated that spider-man using Thunder Breathing while unconscious. This is the potential of the human body."
"Normally, the human body has a self-protection mechanism, and these eight gates are exactly that. Once opened, it's equivalent to removing the body's limitations, granting extraordinary power. However, this isn't necessarily a good thing. Without the body's self-protection mechanism, it's easy to get injured."
Tanjiro asked curiously, "So this Jutsu is for a mutual defeat?"
"Of course not. To avoid injury, one needs a strong physique to protect oneself. Remember, the stronger your body, the safer you will be after opening the gates, and you must never exceed your limits," Uchiha Nagi said.
"Nagi-aniki (Nagi, older brother), what's the last Gate of Death for...? It sounds terrifying..." Zenitsu asked with a look of horror.
"The Gate of Death, as the name implies, means certain death upon opening. You should only train up to the seventh gate. The eighth gate..."
Gulp~
The two boys swallowed their saliva. This Jutsu sounded truly frightening. "Oh, oh, so the last gate is for a mutual kill, right? I get it, Uchiha-aniki~" Inosuke patted his chest, indicating he understood.
"Inosuke, you got the name wrong again. It's Nagi-aniki (Nagi, older brother) from the Uchiha Clan~" Tanjiro reminded him helplessly.
"You haven't even refined Chakra yet, so you can't cultivate it at all..." Zenitsu said, covering his mouth and laughing.
"Bastard, who asked you to care~" A pillow flew past.
"Ah ah ah, Tanjiro, he's bullying me~"
"Can't you two stop arguing and just rest properly?"
Watching the three little ones bickering again, Uchiha Nagi felt a bit dazed, as if he had returned to his past life, to the days of playing around with classmates in the school dormitory.
Unconsciously, Uchiha Nagi walked out of the house and into the herb garden outside. Shinobu Kocho was tending to the medicinal herbs in the garden. She was an expert in poisons, but also a doctor.
Her poisons were mainly for demons, as wisteria flowers were just ordinary plants to humans; some even brewed tea with them. Other herbs were used to make antidotes for members who were poisoned in battle.
Watching Shinobu Kocho busy among the flowers, Uchiha Nagi unconsciously asked a question.
"Do you need help?"
"Oh~ Does Mr. Nagi also understand herbs?" Shinobu Kocho wiped the fine sweat from her forehead and asked.
"Yes, I used to be a Medical Ninja. Although the medical techniques are somewhat different, I still understand the principles of most herbs," Uchiha Nagi said. "Ah, I see. In that case, I won't be polite. Thank you, Mr. Nagi. Some of these herbs are really too delicate; some can't get wet from rain, and some can't be exposed to direct sunlight, so a single oversight can kill them. Please help me move these flowers indoors first,"
"No problem." Uchiha Nagi formed a hand seal, and Multiple Shadow Clone Jutsu appeared.
If it wasn't a life-and-death struggle, Multiple Shadow Clone Jutsu was a very convenient Ninjutsu. Its biggest drawback was probably the superposition of memories at the moment a Shadow Clone died.
The sudden influx of death memories from numerous Shadow Clones could easily cause the main body's brain to malfunction, making it doubt if it had truly died. However, when used just for work, there were no side effects, only fatigue.
"What a convenient Jutsu. I really envy Mr. Nagi; you have such powerful Jutsu in your world," Shinobu Kocho said enviously.
A dozen Shadow Clones helped move some of the medicinal herbs into the house, finishing in two trips.
"Please, Mr. Nagi, help me move these flowers outside to sunbathe. They can only bloom and mature under sunlight," Shinobu Kocho said with a smile.
"They also have a very ancient name, called Lycoris Radiata~"
"Okay~"
Uchiha Nagi moved these Lycoris Radiata outside. There were blue ones, red ones, yellow ones... Among these flowers, one was the blue Lycoris Radiata, the flower Muzan Kibutsuji had desperately sought for a thousand years.
As long as he ate it, he could become a perfect being, able to survive in sunlight. It was ironic to say the least; a demon who could only appear at night, pursuing a flower that could only bloom for one or two hours in the sunlight. That's why he had searched for a thousand years without any news.
Moreover, what he didn't know was that this flower was actually a wild flower, found everywhere. Tanjiro's family even ate it as a wild vegetable... Muzan only realized he couldn't survive in sunlight after killing the doctor who had saved him and transformed him into a demon. Filled with regret, he later looked through the doctor's notes and diaries, discovering that this flower might be the one that could allow him to walk in the sun and become a perfect being.
Over a thousand years, he had probably eaten countless types of plants, big and small. He must have eaten Lycoris Radiata too, but unfortunately, he didn't eat the flowers that bloomed during the day, so it was ineffective.
It wouldn't be an exaggeration to call him a divine farmer, but still, none could allow him to survive in the sunlight, so Muzan even doubted the existence of such a flower.
Uchiha Nagi thought that when he was about to die of old age, he would try to see if the Uchiha Clan's cells could fuse with demon cells, then achieve immortality, and then eat the Lycoris Radiata... But it was still too early. If nothing unexpected happened, he could live for at least another hundred years, so there was no need to change his cell genes. Moreover, not every demon could maintain a human appearance.
Uchiha Nagi had no intention of casually changing his genes. One must know that the Uchiha Clan could evolve to the Six Paths state at their peak, and the Six Paths could completely crush Muzan... After finishing the herb gardening, Shinobu Kocho brewed a cup of tea for Uchiha Nagi, and the two sat in the courtyard, watching the sky and white clouds under the scorching sun.
The gentle summer breeze softly brushed by. Uchiha Nagi picked up the tea and took a sip. A faint fragrance, with a hint of bitterness and sweetness, followed by a lingering sweetness after drinking. It was wisteria flower tea.
"What a warm day it is. If only the night sky could be this peaceful..." Shinobu Kocho looked at the sun, relaxed, and smiled.
Uchiha Nagi didn't speak. There was a time when he also wished to live such a carefree life, but this world was not peaceful either. Kagome, the girl he had known for a few days who was killed, involuntarily came to mind.
If he hadn't gone to get medicine for himself, her fate would probably have been completely different... Uchiha Nagi took out an instrument and played the melody of [Beloved]. The faint and melancholic music began to spread throughout the Butterfly Mansion under the scorching sun... Clap clap clap clap — The song ended, and two sounds of applause were heard.
"What a beautiful and melancholic piece. Oh, Mr. Muichiro, why are you here?" Shinobu Kocho clapped her hands and then noticed another round of applause, which came from the Mist Pillar, Tokito Muichiro.
"Um... I think I've refined Chakra..."
