For Logan, it was quite easy for him to get to the earth station from where he was. After all, a teleporter in his household was linked to all the stations around the universe, thanks to the Green families influence.
Before leaving, he made sure Ash was prepared and ready. Just in case there were any unexpected visits from Mona while he was away, based on his calculations though, he should be fine. At the moment Mona was busy trying to see if there was another demon tier beast she could locate with the device.
The device, unfortunately, was quite a manual one. On the planet itself where the scan would be made, six prongs would have to be placed around the sphere-like object, covering the entire planet. Only then could the device be activated and in the system, it would inform one if there was a demon tier beast or not.
