?Chapter 820: Chapter 339 Mechanical Sparrow Chapter 820: Chapter 339 Mechanical Sparrow The drone took off from Dream Island at just past eight o’clock local time, by which time the skies of Dream Island had darkened. However, as the drone flew westward, it actually caught up with the twilight zone, seeing the sun once again. And as the drone continued further west, the time on the ground became earlier, as if Yan Fei was traveling through time and space with the drone, which was quite amazing.

The drone’s flight altitude reached 25,000 meters and its speed hit 2.5 times the speed of sound, or 3060 kilometers per hour. This velocity ensured it could catch up with and continually surpass the time zone line. If it maintained its course, it could even remain perpetually bathed in sunlight.

Unlike previous flights to Africa, the drone now had radar stealth capability, meaning it had no concerns about being detected by other nations’ air defense radars. Therefore, it could fly directly over other countries’ airspace without being noticed.
