However, considering the difficulty of cultivating the 'Twelve Palaces' and the need for secrecy, there actually weren't many experimental white mice Shinji could bring in to cultivate with him.
" Haku, Karin, Yakumo, Sasuke, Neji, Kimimaro, and... Shion?"
After thinking it over, these were the only ones Shinji could come up with.
He then frowned, feeling that some of them weren't suitable.
Take Haku, for example. He had invested a great deal of effort into cultivating the 'Breathing Technique,' and now he was only one thin layer away from the technique's highest realm, the 'Clear World.'
Under these circumstances, disrupting his cultivation plan and having him switch to cultivating the 'Twelve Palaces' might not be a good thing.
Karin was also not particularly suited to cultivating the 'Twelve Palaces.'
That wasn't to say Karin couldn't learn the 'Twelve Palaces.' Rather, given her current strength, she no longer had much need for it.
A body art secret technique like the 'Twelve Palaces' didn't make someone stronger simply by learning more techniques.
Every form of Taijutsu, even the most basic, possessed the ability to develop the body's potential. It was merely that high-level Taijutsu secret techniques were more efficient at doing so.
If the human body's potential were compared to 100 percent,
then Tsunade's 'Super Strength,' Might Guy's 'Eight Gates,' and the Fourth Raikage's 'Lightning Release Chakra Mode' would all be top-level Taijutsu secret techniques capable of developing more than 80 percent of the human body's potential.
Shinji reckoned that because his 'Twelve Palaces' specialized in developing the body's potential, and because he had continually improved it, it might have already surpassed those top-level Taijutsu secret techniques, reaching a development rate of more than 90 percent.
That was essentially the limit. Even if Shinji also cultivated 'Super Strength,' 'Eight Gates,' and 'Lightning
