Nameless's boost in strength naturally left her overjoyed.
Along with his own delight, Shinji also understood that the credit didn't all belong to the Twelve Palaces.
In his view, Nameless, with Yachihoko, should have been far stronger than an ordinary Mangekyo Uchiha in the first place.
It was just that the Uchiha Clan had been too wary of Nameless's Yachihoko. They had only wanted to use her as a weapon, never considering that they should carefully train her. That was why her abilities had become so uneven.
In other words,
Nameless's current strength was what she should have been capable of all along.
This also reaffirmed Shinji's belief that before reaching Six Paths level and turning the body entirely into chakra, a ninja's ability to control their body directly determined whether they could fully realize their potential.
The Twelve Palaces he had developed might not be the most powerful Taijutsu secret art in the Shinobi World, but it was undoubtedly the Taijutsu secret art best suited to developing the body and drawing out one's potential!
After a simple warm-up, Shinji and Nameless began an intense Taijutsu spar in Takamagahara.
Both had Uchiha blood, had strengthened their bodies with transplanted First Hokage cells, and had trained in the Twelve Palaces. In terms of their physical foundations, they were roughly evenly matched.
In other respects, Shinji had a much deeper grasp of the Twelve Palaces, and the insight of his Six Tomoe Rinnegan surpassed that of Nameless's Eternal Mangekyo Sharingan.

After sparring for a full hour, the two finally stopped.
Even with their physiques, an hour of high-intensity Taijutsu combat was enough to leave them utterly
