"What is Senjutsu? My own damn seedlings—there's actually chakra I don't know about?!"
Kaguya-hime froze for a moment, then flew into a rage. Just how many pieces had her two rebellious sons split the Ten-Tails' chakra into after separating from her? Why was her lost chakra scattered all over the world?
"It's Natural Energy!"
Fuyuki suddenly remembered that Senjutsu Chakra was produced by mixing Natural Energy with chakra. Strictly speaking, it couldn't simply be called Senjutsu. The real question was how to absorb Natural Energy without suddenly dropping dead.
"Natural Energy can kill people?" Kaguya-hime asked, looking astonished.
Fuyuki: "???"
"Isn't Natural Energy just chakra? You all use chakra. How can chakra kill people?" Kaguya-hime asked, confused.
In truth, humans and aliens were really different. Human chakra was made by combining physical and spiritual energy, but aliens were different. They absorbed Natural Energy directly.
Natural Energy that could poison humans was just an ordinary nutritional supplement to aliens from the Otsutsuki Main Branch. It slowly replenished their chakra. If they wanted to replenish it quickly, they needed to eat an Elixir or a Chakra Fruit.
After hearing Kaguya-hime explain the Otsutsuki technology tree, Fuyuki fell silent.
Maybe, apart from that useless Fisherman, all the other members of the Otsutsuki Main Branch were powerhouses?
At the same time, Fuyuki learned a secret about the Otsutsuki clan's cosmic family.
The Ten-Tails was an artificial sapling, created to absorb Natural Energy and chakra from within planets. It was a Biological Weapon made by the Otsutsuki Clan, who possessed formidable biotechnology and chakra technology.
Fuyuki already knew a little of this, but hearing it explained by Kaguya-hime, a member of the Otsutsuki Main Branch, was far more shocking than anything he'd learned from the anime.
Now that he knew members of the Otsutsuki Clan
