The complete Byakugan has no blind spots, and the Hyuga Main Family cannot control the death of the Branch Family.
As for the Caged Bird, it does serve to protect the Branch Family, but Konoha has already merged with the Hidden Sand Village and is about to annex the Land of Rain and the Land of Rivers, soon becoming the largest of the Great Ninja Villages in the Ninja World.
Now it can be said that the Hidden Rock and Hidden Cloud Villages are both keeping a low profile, and they are too busy restoring their strength and training ninjas to bother watching the Hyuga Clan.
Moreover, Uchiha Yoichi has also told the Hyuga Clan that if there is any issue with the Bloodline leaking, the village will seek justice for Konoha's ninjas. Unfortunately, the elder council of the Hyuga is unwilling to abolish the Caged Bird; whether it's truly for the good of the Byakugan or just for their accustomed Main Family rule is unknown.
After the Caged Bird Curse Seal on Hyuga Satomi was lifted, she felt as if she had broken free from a shackle, and the range of her Byakugan's vision greatly extended.
"Teacher Yoichi, I feel great now. When do we set off for the mission you mentioned?"
Hyuga Satomi had never felt this good before. After breaking free from the Caged Bird, she felt unshackled, and her gaze towards Uchiha Yoichi was as tender as honey.
If Kurenai can achieve it, so can I... no, why compare to Kurenai? If Nohara Rin can do it, then I can too!
Hyuga Satomi inched a bit closer, involuntarily looking up at Uchiha Yoichi's face, which had not changed one bit over the years and had always been kind to her as a teacher.
Since her sister got married, she had less time to care for her, and after that, only Teacher Yoichi cared for her. Without Yoichi, Hyuga Satomi felt she wouldn't even have learned the Gentle Fist.
'How wonderful~!'
Hyuga Satomi thought blissfully to herself, but she was suddenly brought back to reality when she saw a hand waving in front of her.
"Satomi? Are you okay?"
"No, I'm fine. Sorry, Teacher Yoichi, I was a bit distracted earlier."
Hyuga Satomi quickly apologized sheepishly.
Uchiha Yoichi shook his head and said, "It's fine. Let me repeat, apart from an unfamiliar enemy recently, everything is okay in the village, so you should come along with me then."
In fact, he could go alone, but since it involved Otsutsuki Hamura, the Byakugan might prove useful; and if any of the Otsutsuki Clan members on the Moon are still alive, they might share some Tenseigan memories with those who have the Byakugan.
Uchiha Yoichi remembered a space tunnel that led directly to the center of the Moon.
He recalled a glowing spring beneath a certain waterfall within the Land of Fire; finding this would enable passage to the Moon's interior through a space tunnel.
However, this seemed troublesome, and it might be easier to simply fly to the Moon and break in from the surface...
"Teacher Yoichi, are you thinking of something troublesome?"
Seeing Uchiha Yoichi frown slightly, Hyuga Satomi boldly reached out to press gently on Uchiha Yoichi's forehead.
Uchiha Yoichi smiled and said, "Nothing special. If you're free today, let's set off now."
Nonetheless, he decided to go by himself; sending subordinate ninjas might cause unnecessary delays, and using the Byakugan wasn't preferable over just flying there himself.
Hyuga Satomi, surprised, asked, "Right now?"
"Yes, do you need to go home and inform anyone?"
"Well... no need, I'm ready to go anytime."
Hyuga Satomi shook her head. After her sister married, she lived alone, so it didn't matter whether she went back or not. She spoke more with Yuhi Kurenai in a day than with her own clan in a month.
"Then let's set off; I'll take you to the Moon."
Having said that, Uchiha Yoichi's eyes transformed into the Six-Tomoe Rinnegan, and the Tamoe Feather Robe and Truth-Seeking Orb appeared on him.
He had already informed Mikota and Minami before leaving, so being away for a day or two was no issue.
"Wait here for me for a moment, Satomi."
To reach the Moon, Space-Time Ninjutsu was the fastest, so Uchiha Yoichi first went to find the Kamui Clone.
After locating the Kamui Clone, he had it put the Potara Earrings on its other ear, allowing the Kamui Clone to merge with Uchiha Yoichi.
Once everything was set, Uchiha Yoichi returned to Hyuga Satomi, enveloped her in Chakra, and said, "Alright, let's go."
With that, the space around them warped simultaneously, and they disappeared from where they stood.
The next moment, when Uchiha Yoichi and Hyuga Satomi reappeared, they had already left Earth and stood amid the cosmos.
"Is this... Teacher Yoichi, have we left the Ninja World?"
Seeing the dark environment of the cosmos and the planet beneath her feet, Hyuga Satomi was filled with shock; upon closer inspection, she could see the vast yellow deserts and the deep blue oceans of the Ninja World Planet.
Standing in the cosmos for the first time, looking back at the Ninja World, Hyuga Satomi was awestruck. When she came to her senses, she looked at Uchiha Yoichi with admiration, viewing her teacher akin to a god.
"That's right. Next, we'll head to the Moon. Satomi, make sure to listen to me then."
Uchiha Yoichi was also visiting the Moon for the first time, but he wasn't as surprised as Hyuga Satomi. He experimented a little, finding that even without Chakra, he could survive in the cosmos.
Even without the need to breathe, his Genetic Primordial Energy and Chakra would sustain him for a long time, making it unlikely to deplete completely.
