Land of Wind.
The sky was clear and cloudless, with visibility stretching for miles.
A golden cloud flew along the coastline beneath the blazing sun.
It was Rasa's Gold Dust Sand Cushion.
He sat on it wearing a wide-brimmed hat against the sun, with plenty of drinking water beside him.
Reconnaissance was hard work.
To get a good view, he had to fly high.
And the air above the desert was no pleasant place. It was hot and dry.
Strong as Rasa was, he could not defy nature. He still got dehydrated.
He did not have to walk, but simply flying on the Gold Dust Sand Cushion was hot enough.
Still, his efforts paid off.
After surveying a third of the Land of Wind's coastline,
Rasa finally spotted a use for Thermally Conductive Crystal Ore at a gourd-shaped inlet.
The ground was covered with enormous, unusual hemispheres.
A faint orange-red glow covered them, the natural color of heated Thermally Conductive Crystal Ore.
Rasa watched from above for hours before he understood what the installation was.
It was a Solar-Powered Seawater Desalination Device!
A channel dug beside the sea outside the inlet drew seawater inside.
Parabolic mirrors atop the hemispheres concentrated the sun's heat on the seawater below, superheating it until it evaporated.
The high-pressure steam was then released and condensed into fresh water, collected by nets on the hemispheres and sent away through pipes.
"The output is this high?!"
Solar-powered desalination was nothing new. Water evaporating into vapor was, after all, a simple physical process.
But he had never seen one produce hundreds of cubic meters of fresh water an hour.
Rasa sat on his Gold Dust Sand Cushion as though in a dream.
He had been Kazekage, after all.
He knew how important this technology was to the entire
