The drone flew west.
Before long, it reached the Baihetan Hydropower Station nestled amid the continuous mountains of the Hengduan Mountains.
The waters flowing down from the upstream Jinsha River were blocked here by a 300-meter-class double-curvature arch dam, forming a super reservoir with a storage water level of 825 meters.
"Truly the pinnacle of the hydropower industry."
"This dam is practically a towering wall—more formidable than the walls in Attack on Titan."
Chen Yi guided the drone lower and circled the area, taking all kinds of photos.
After finishing the photos, he continued onward.
Further ahead lay the Three Rivers Confluence region.
The Jinsha, Mekong, and Salween Rivers flowed from north to south in a formation resembling the Chinese character for river.
As the drone swept over the skies above the three rivers, it startled flocks of Black-necked Cranes and Black Storks, leaving lively silhouettes in Chen Yi's footage.
"Maybe I can take an aerial photography trip sometime."
"With my drone doing the aerial filming, wouldn't that be even more exciting than Aerial Planet?"
After crossing the Three Rivers Confluence region, Chen Yi entered the Himalayan Mountains.
One towering snow-covered peak after another swept past beneath the camera.
Between the mountains lay valleys and flatlands, where the mysterious Yarlung Tsangpo River flowed slowly onward.
Meltwater from the Himalayan Mountains had created this great river, the highest-elevation river in the world and fourth in the world by water volume.
He followed the Yarlung Tsangpo River's course for a while.
Before long, the drone arrived at the highest peak in the Himalayas.
—Mount Everest.
Before the drone could descend from the sky,
the infrared scanner had already detected tiny yet bright red dots scattered across Mount Everest's surface.
Chen Yi slowed the drone down.
He wanted to avoid the sonic boom
