After the optimal moment had arrived, Yan Fei didn't hesitate. He controlled the drone to descend rapidly, plummeting from an altitude of 25,000 meters to just above the pond below. The drone hovered in mid-air, Yan Fei opened the cockpit door, jumped down from the drone, landed on the ground, and then the drone immediately ascended, returning to the 25,000 meters altitude.
Although Yan Fei had reached the ground, he didn't allow himself to be directly exposed to the outside air. He was wearing a set of exoskeleton armor and kept himself hidden in the nearby woods. The exoskeleton armor was designed with excellent sealing properties, ensuring that the outside air could not enter, thus avoiding the risk of Yan Fei getting infected by the Ebola virus in the air.
