Further information was not elaborated in the announcement, but not long after its release, the Imperial Court issued another notice concerning the redrawing of the Blue Star map.
The notice stated that all those who registered for this mission would have a 3D Sonar Detector installed on their main ship for free. The participants only needed to navigate their equipped ships toward the uncharted areas on the map, where the detector could automatically draft the map.
Dong Tianyu speculated that the Imperial Court must have received some Special Information through that group of foreigners to launch such a mission.
Although the Imperial Court issued many notices over these months, only three were useful to Dong Tianyu.
Having understood the information he missed while underwater, Dong Tianyu immediately navigated based on the tablet's positioning and directed the Companion Spiritual Treasure towards Magic City Base Number Three.
