Shishou's secret base.
"You... you also know the Flying Thunder God technique..."
Seeing herself instantly appear inside a room, Hyuga Natsu was shocked. As a Jonin of the Hyuga branch family, she naturally recognized the technique Shishou used. After all, the Hyuga clan had been searching for the recently famous Flying Thunder God user.
"It's not that I also know the Flying Thunder God technique; it's that I am the Flying Thunder God user."
Shishou gently pinched Natsu's small nose with a light laugh.
"You are the Flying Thunder God user?"
Natsu's eyes widened in disbelief. Remembering how Lord Hiashi discussed with him about contacting the Flying Thunder God user and negotiating terms, she found it absurd.
"This is my secret, okay? Don't tell anyone."
Holding Natsu's small hand, Shishou walked down from the teleportation platform. After fully extracting Hashirama cells, he had sent his female assistant to handle fertilizer development, leaving the base empty except for him and Natsu.
"No wonder you said the Flying Thunder God user owed you a favor. You and yourself... it's all up to you. Lord Hiashi has really been deceived by you!"
Thinking Shishou had something bad planned, Natsu nervously tried to distract herself by talking.
"Hahaha, he's not the worst off."
Shishou laughed.
"Do you mean the Third Hokage is the one most deceived by you?"
Natsu realized and almost laughed but held back.
"Hahaha, who else could it be?"
Thinking about how the Third had asked him to investigate himself, Shishou couldn't help but laugh out loud.
"Come on, I'll show you around. You'll be staying here for a while."
Pulling Natsu along, Shishou strolled around the base.
"This will be your room."
Entering a large room, Shishou pointed and said.
"This is really for me?" Natsu was amazed at the modern, luxurious room.
"Of course. Get used to it for a while, then I'll give you tasks."
Tapping Natsu's forehead, Shishou vanished.
Natsu touched her forehead and entered the room. Seeing the luxurious bathroom, study, bedroom, private gym, and playroom, she was astonished.
As a branch family member destined to serve the main family, she had never imagined such luxury.
"Wow, so soft."
Lying on the soft bed, Natsu couldn't help but moan.
"If this is a dream, I hope it never ends."
...
Night.
Konoha.
In Tsunade's home.
After using a stick to discipline Shizune into sleep, Shishou sat at his desk, recording the text and technique he had seen on the Hyuga stone monument with his parasitic insects.
The technique to find the spatial anomaly required Hyuga blood, so he planned to teach Natsu to find it for him.
In the original story, Naruto and others found the spatial anomaly quickly because they had clues left by Toneri Otsutsuki. Without those clues, Shishou had to search slowly.
After recording, Shishou put the scroll in his pocket.
"One o'clock. Lady Hyuga should be asleep by now."
Checking the time, Shishou transformed into his alias, growing a beard, and appeared in Hyuga Rinmei's room.
He planned to inject her with life energy again, keeping her alive to manipulate Hiashi Hyuga.
"Madam, you are quite wealthy..."
Mumbling, Shishou reached to knock Rinmei unconscious.
"Who..."
Suddenly, Rinmei grabbed Shishou's hand. She couldn't sleep due to her thoughts and accidentally caught him.
Genjutsu: Binding Illusion!
The moment Rinmei grabbed him, Shishou used his Mangekyo Sharingan to control her. He quickly exited and hypnotized the alerted Hyuga guards. Despite the Byakugan's resistance to genjutsu, they were no match for his Mangekyo.
After ensuring the guards were neutralized, he returned to Rinmei, laughing softly.
"Madam, why aren't you sleeping? Were you waiting for me?"
Rinmei coldly asked, "Who are you and why are you in my room?"
Squatting before Rinmei, Shishou lifted her chin to see her face by the moonlight.
Feeling his touch, Rinmei wanted to resist but couldn't move, letting him do as he pleased.
Her delicate features and elegant, cold demeanor were different from Mikoto's.
Thinking this, Shishou laughed, "Madam, haven't you been looking for me?"
Rinmei was shocked, "You are the Flying Thunder God user!"
"Correct!"
"I didn't want to treat you initially, so I set difficult terms. But because Mr. Lurigan repaid a favor, I came to check your condition."
"If I'm confident I can cure you, I will make demands to the Hyuga clan tomorrow."
"If not, I'll refuse."
"That's why I'm here tonight."
Sitting before her, Shishou lied smoothly.
"Do you think you can cure me?"
Rinmei nervously asked. She knew about the deal between Hiashi and Mr. Lurigan and the impossible demands set by the Flying Thunder God user.
Those Hyuga elders would rather she die than let the main family's Byakugan be passed on.
Knowing this, she was desperate and could only hope Mr. Lurigan would succeed.
"I need to examine your body to know," Shishou said, glancing at her figure.
Blushing, Rinmei hesitated but agreed, "I am willing to let you examine."
Seeing her reaction, Shishou looked out the window at the moonlight and laughed again.
"Madam, is this how you ask for help?"
