It flew thousands of kilometers into the distance and only returned when the battery was low. Everything it photographed along the way was automatically compiled by the computer to form a detailed map of the other world.
On the other side of the light spot — in reality, this sea region had been completely blocked off by warships from the four continents of the Earth Federation. Except for the ships of the foundation, any ships of any other parties were not allowed to approach within a radius of 100 miles of this area.
At this time, several survey ships transformed from freighters were parked side by side under the light spot. Countless materials, android, and drones were constantly being transported into the light spot, turning the previous outpost into a sturdier fortress.
The purpose for doing this was to prevent possible attacks from other world's creatures.
