Yan Fei continued to control the Drone as it glided stealthily under the sea. While familiarizing himself with the Drone's underwater navigation capabilities, he also recorded various data from it and simultaneously mapped out the seabed's terrain.
Compared to flying in the sky, the Drone's underwater travel consumed a great deal more Energy Points. After all, it had to withstand the sea water's pressure and break through the water's resistance to achieve a higher speed. According to the Auxiliary Brain's comparison of the Drone's Energy Point consumption at various stages, a full charge of Energy Points could allow the Drone to fly for 5-10 hours in the air, but could only sustain underwater travel for 2.5-5 hours.
In contrast, the energy consumption of underwater travel was double that of flight in the air. As for the Quantum Radar, although its maximum scanning distance was reduced, its consumption of Energy Points did not decrease at all.
