"I'm sorry, Tsunade-sensei..."
Seeing Tsunade's heartbreak, Gengetsu felt somewhat regretful. During the Second Shinobi War, both Nawaki and Dan could be said to have died from shattered internal organs. The former had been blown up by an Exploding Tag trap, while the cause of the latter's death was unknown. But Dan had mastered the Spirit Transformation Technique, so it could be guessed that an enemy had ambushed him at close range and injured his vital organs. Even with Tsunade's medical abilities, she had been unable to save him.
Perhaps that was precisely why the technique Creation Rebirth had been created.
Tsunade turned away, the wind lifting her long hair. At that moment, she was no longer one of the Sannin who had once dominated the battlefield, but merely an ordinary woman.
After a moment, Tsunade turned back with an expressionless face. "Why do you need a clone body to practice Sage Art?"
Before Gengetsu could speak, Little Katsuyu on his shoulder said, "Lady Tsunade, Lord Gengetsu is like you. He can't sense Natural Energy!"
"So there are techniques you can't learn too!"
Tsunade seemed to take some delight in his misfortune again, then pondered. "So you want to use Hashirama's Grandfather's cells to cultivate a clone body, test whether it can master Sage Art, and then implant Hashirama's Grandfather's cells into your own body?"
"No!"
Gengetsu shook his head and pointed at his brain. "The inability to sense Natural Energy isn't caused by the body. The key is here—it's the mind! Or rather, a person's spiritual will, the Seven Emotions and Six Desires!"
Tsunade frowned deeply after hearing that. What Gengetsu said seemed far too abstract.
Little Katsuyu, perched on Gengetsu's shoulder, immediately explained, "Lady Tsunade, the reason you can't sense Natural Energy is because your spiritual will isn't pure
