Natural Energy

Shamu closed the scroll.

Something kept turning over in his mind.

Konoha, Orochimaru, Kakashi, Puppet Curse, Kakuzu, Obito.

A vague idea had taken shape in Shamu's mind.

Still, it would be a pity if Kakuzu ran off.

Shamu planned to meet Kakuzu in person.

Aokimaru was still waiting nearby. Shamu took out some paper and a pen, quickly wrote a few lines, then pulled out a Flying Thunder God marker.

"Take this back to Tenten."

"Yes, Lord Shamu."

After putting everything away, Aokimaru vanished from the area.

Shamu walked out of the tent and saw Yakushi Kabuto inspecting the Rainbow Crystal Barriers.

At night, without any light, the Rainbow Crystal Barriers had dimmed as well.

The underground heating equipment was also running more slowly.

"Lord Shamu, the technology behind these geothermal devices isn't particularly advanced. They simply chose an excellent location."

"Only the materials used for the Rainbow Crystal Barriers are unusual. I've never seen this technology before."

Shamu had specifically brought Yakushi Kabuto here because he was highly educated and knew Sage Art.

That made him the best person to investigate this place.

"It doesn't matter if we can't find the source for now. We can use it first."

"I intend to turn this place into a site dedicated to cultivating Sage Mode."

"After all, it's difficult to obtain Natural Energy in the outside world."

Yakushi Kabuto nodded in deep agreement. Anyone who could activate Sage Mode would see their strength rise by several levels.

But Sage Mode's greatest weakness was how difficult it was to obtain Natural Energy.

It was basically one hour of charging for three minutes of fighting.

Absorbing Natural Energy outside was extremely slow, so it simply could not be used in routine combat.

Only someone with abundant Chakra like Naruto could use Shadow Clones
