The reconnaissance drones launched from "Atlantis" have conducted sonar surveys on many caves, but this detection technology is not always foolproof and is often influenced by depth, complex geological structures, and sonar power.
The harsh winter on Antalu Planet arrives early, affecting both the southern and northern hemispheres uniformly, unlike Blue Star where the equator differentiates between summer and winter. The seasonal changes on the entire planet are completely synchronized, and the temperature fluctuations are extreme. Even near Antalu's equatorial line, once winter sets in, it becomes like a frigid hell, directly limiting the operating capacity of drones. With dry ice blizzards kicking up, no drone or aircraft can safely take flight.
