Uchiha Yoichi created hundreds of shadow clones, quickly gathering all of the Otsutsuki heritage on the Moon into the hall.
The Otsutsuki Race on the Moon developed incredibly well; their puppetry jutsu had advanced with Chakra automation, allowing for wireless transmission and control. Although this technology relied on the Tenseigan, it was far superior to anything in the Ninja World.
"Teacher Yoichi, I'm capable of controlling the Tenseigan now, but each use consumes a massive amount of Chakra. Without the Chakra you provided me, I might die after just one use."
Hyuga Satomi walked briskly over to Uchiha Yoichi, smiling as she spoke. After coming to the Moon, Satomi's reserved personality began to brighten.
Seeing Yuhi Kurenai getting so affectionately close with Teacher Yoichi used to make her very envious. But now, on the Moon, she could do the same.
"And also, the Byakugan... I think I felt something strange just now. Was it you who helped me, Teacher Yoichi?"
Hyuga Satomi leaned in very close as she asked, almost touching Uchiha Yoichi's side. In the vast hall, this behavior felt a bit unnatural, but she pretended to stretch her neck to look at the book in Uchiha Yoichi's hand to justify her proximity.
"Don't worry about the Chakra. I'll seal enough into you to drive the Tenseigan; for the next few years, I'm afraid we'll have to rely on you to control this Tenseigan, Satomi."
Uchiha Yoichi continued flipping through the book. The Tenseigan's power was too immense; when fully unleashed, it was even stronger than a Tailed Beast, and could only be driven by the power of the Byakugan.
Such tremendous power certainly couldn't be left in the hands of others. Hyuga Satomi was the most suitable candidate for this responsibility.
"Satomi, with your current power, how many puppets can you control? Can the Tenseigan be brought back to Konoha?"
Hyuga Satomi thought for a moment before replying, "It can be taken back. The Tenseigan's power has been sealed, but it's best to take with us the device that disperses its energy, so we can control the puppets even back in Konoha... As for the puppets, they don't require my own power, only the power of the Tenseigan."
This is the Tenseigan formed by the aggregation of all the Byakugan on the Moon. As long as it's not destroyed, its power can regenerate automatically; moreover, the Moon's Branch Family once pushed the Tenseigan into battle, destroying the Main Family, so there's no problem in moving it.
It hasn't been long since the battle between the Branch Family and the Main Family occurred. The Chakra information preserved by the remnants of the Main Family is still extensive, and they're hoping that descendants will encounter and stop the Branch Family's madness. All the information on the Tenseigan was passed down through Chakra to the waiting Byakugan Clan members.
"Let's head back then. Leave a third of the puppets here for further development...."
Having said that, Uchiha Yoichi stood up but accidentally brushed against Hyuga Satomi beside him, then said, "Sorry, Satomi."
"Teacher Yoichi, it's alright..."
Hyuga Satomi's cheeks blushed slightly, and she then asked, "Teacher Yoichi, will the control of the Tenseigan be entrusted to me next?"
Uchiha Yoichi nodded, "Yes, you're the only one I can trust with it. What's the matter?"
Hyuga Satomi lowered her head, saying, "Can I make a request, Teacher Yoichi?"
"What kind of request?"
"...I haven't decided yet, but I promise it won't trouble you, Teacher Yoichi. I'll tell you when the time comes."
Uchiha Yoichi looked at the shy Hyuga Satomi, paused to think, then said, "Alright, whenever you're ready. I'll try my best to help, even if you want to become the Clan Leader of the Hyuga Clan."
Hyuga Satomi hummed without speaking. Why would she want to become the Clan Leader? The Caged Bird was lifted, and she controlled such a powerful Tenseigan, with Teacher Yoichi behind her. Would anyone from the Hyuga Main Family dare say anything to her?
What she wanted was Teacher Yoichi's promise. With this assurance, things would be much easier. Hyuga Satomi no longer saw Yuhi Kurenai as a rival.
Little Yuhi Kurenai was no longer a match for her; Hyuga Satomi had now set her sights on surpassing Nohara Rin!
Subsequently, Uchiha Yoichi and Hyuga Satomi tidied things up, storing the heritage texts in a storage scroll, while the massive Tenseigan and equipment were directly transferred into space by the Kamui Clone.
As for returning, there was no need to walk the lunar path again. They could simply use the space passage within the Moon that connected to the Ninja World planet.
After passing through the space passage and then through the lake, Uchiha Yoichi took Hyuga Satomi airborne, sensing their location and confirming Konoha's direction.
"It's quite close; we should develop this place further in the future."
Finishing here, Uchiha Yoichi immediately flew back with Hyuga Satomi. Once they reached the village, he let Satomi down, telling her, "Satomi, in the next couple of days, I'll compile everything from the Moon into a Sealing Book, and then you can feel free to look through it, or share it with others."
The heritage of the Otsutsuki Race on the Moon was remarkably complete, including not only all of the Hyuga Clan's Gentle Fist Taijutsu techniques, but also the Gods Air Attack technique, presumably left by Otsutsuki Hamura. However, most people couldn't even execute one strike.
"Thank you, Teacher Yoichi, um...."
Before Hyuga Satomi could finish her sentence, she felt a sudden pain in her eye, causing her to close her eyes and rub them gently.
"It's probably a sign of the Byakugan's evolution. Go home and rest well. If anything feels wrong, come find me or go to Konoha Hospital right away."
