章 308: Chapter 167 Casino Showdown_3

Yang Song had not been long at sea after driving the yacht away from Tianjin Pier when his location went beyond the maximum surveillance range of Yan Fei's position locator. However, Yan Fei had been prepared for this, and while he had rushed to Beijing from Shanghai that morning, he had controlled a drone to travel northward from near the coast of Shanghai, then enter the Bohai Bay and secretly position itself at the seabed near Tianjin. Thus, when Yang Song's yacht set out to sea, the drone, with the help of Yan Fei's position locator signal, instantly found the yacht's location. Thereafter, the drone continuously followed the yacht as it traveled outwards, and when the position locator reached its furthest distance, the drone took over monitoring from Yang Liu, with the drone and the position locator completing a perfect signal handover.
