Minato rarely had time to cook, and Gengetsu ate with great gusto.
Kushina watched with a smile. She loved watching Gengetsu eat; it gave her a strong sense of accomplishment, even though she had not made the food before her.
Minato was gentle and refined. Just as when he fought, he ate with a steady rhythm—he seemed slow, but was actually fast. He finished even before the wolfing-down Gengetsu, then asked, "Gengetsu, how is your Immortal Cultivation plan progressing?"
Kushina asked curiously as well, "A few days ago, you mentioned that you had already cultivated clones. Have you found a way to train in Sage Art?"
"Mm, I've already cultivated two clones, but I've also spent all my money. The experiments had a few bumps along the way, but so far they've confirmed that my previous deductions were correct. As long as I find the point of entry into Unity of Heaven and Man, sensing Natural Energy should not be a problem. Then I'll naturally be able to train in Sage Art!"
As he spoke, Gengetsu asked, "Brother Minato, you've already mastered Sage Art, haven't you?"
"Ha, I have indeed mastered it! But I'm not particularly skilled at it. It takes too long to refine Sage Chakra, and I can't maintain it for long either!"
Minato looked a little embarrassed. Though he had mastered Sage Art, it was truly rather useless to him.
In fact, Jiraiya had the same problem. The preparation time was too long, while the duration was too short. However, Jiraiya could extend the duration of his Sage Art through the two Sages, Fukasaku and Shima.
The root of the issue was still sensing Natural Energy. Gengetsu and Tsunade could not sense it at all, while Minato and Jiraiya could sense it, but absorbed it very slowly.
