"Chakra has this kind of problem?" Haruno Sakura's little head popped up with a question mark.
"How should I put it?" Sun Wukong rested his chin in one hand, twirling a small stick in the other, "Chakra isn't a power that originally existed on Earth. To use this power, you need to refine it from within yourself and then release Ninjutsu. You also need hand seals to control this energy."
"Don't you find that strange?"
"Why do you need such complicated hand seals to use a power extracted from within oneself?"
Haruno Sakura was stunned.
In her little head, she couldn't immediately think of an answer to the question.
"The bodily energy belongs to me, and the spiritual energy is also mine, but the Chakra formed by the combination of the two isn't mine?" It took Sakura a while to grasp the key to the problem.
