Chapter 521 Battle Armor

Two days later, after completing his preparations, Yan Fei set off from Dream Island on a drone, crossing the Pacific Ocean. By the time he reached the California Nevada Mountains on the US West Coast, it was 10 p.m. local time on Dream Island and 4 a.m. Western Standard Time.

The drone had been flying for over three hours after departing from Dream Island. Although its energy points were less than half, as long as it didn't squander the energy recklessly, these points could still sustain the drone for more than two hours of flight. During this period, if the drone did not land on the United States mainland, it would undergo a data refresh two hours later. By then, the drone's energy points would be restored to full, enabling it to provide uninterrupted battle support for Yan Fei.
