Chapter 1657 - Chapter 642: Fortress Wreckage_3

After arriving at the territorial waters where the Space Fortress Core Wreckage crashed, under Yan Fei's control, the Drone vertically plunged into the sea. As soon as the Drone entered the sea, it quickly transformed, switching from flight mode to Submarine Mode. The Drone began diving downward into the dark seabed. In this area, apart from a large number of fish schools, no artificial ships existed anymore. Yan Fei could navigate recklessly here without fearing being discovered by his enemies.
