"It is really too difficult to control this natural energy." Uzumaki Jun felt the natural energy filling the surroundings and sighed helplessly, muttering, "No wonder chakra ultimately became the mainstream..."
It was just like the principle of bad money driving out good money. No one cared whether it was good or bad; as long as it could accomplish what they wanted to do, then...
It was good money.
Chakra could precisely do what natural energy could do, and it was easier to learn and control...
"I wonder if anyone knows how to control natural energy at this time?" Uzumaki Jun touched his chin and fell into thought. According to what was told in the anime, the Sage of Six Paths traveled throughout the ninja world and only found a toad that could use sage art, and furthermore...
It was still senjutsu chakra!!
As for the rest...
