?Chapter 450: Chapter 219: The 4th upgrade_2 Chapter 450: Chapter 219: The 4th upgrade_2 The drone, after a data refresh, could fly at top speed for 5 hours, reaching a terrifying distance of 18,360 kilometers. Of course, this is only the theoretical maximum flight distance. In reality, because Yan Fei utilizes Quantum Radar and the Auxiliary Brain, and since the drone needs to evade radar detection by submerging underground, encountering the resistance of seawater and withstanding its pressure, all these factors would heavily drain the drone’s Energy Points. Therefore, the drone’s maximum distance would not reach 18,360 kilometers, but would in fact be shorter.

The straight-line distance between Shanghai and Misty Island is 3,000 kilometers. If the drone were to actually fly back and forth between Misty Island and Shanghai, after each data refresh the drone could at most make two round trips, which equals 12,000 kilometers.

Based on this efficiency, for Yan Fei to transport all 24,000 tons of Upgrade Materials from Shanghai to Misty Island, he would need to make 15-17 round trips between the two locations. According to the calculations above, this would require 8-9 days. However, Yan Fei had already put in so much effort to upgrade the drone, even facing a life-and-death crisis when snatching the Upgrade Essential Items. Now, it was just a matter of long-distance material transportation without any risk, at most a matter of spending some time. Compared to previous hardships, the current situation was much easier for Yan Fei; such a duration was certainly tolerable for him.
