After taking the liquid Moriya and Arc left the meeting room. Arc hurried to return to the Imperial capital, but Moriya didn't go.
He stayed in the hotel as he supervised the Space gate construction in the woods nearby.
The Space gate was actually not hard to construct provided that there are all the materials available. And they have all the materials and almost finished the work prior to the war. But due to the war, they were asked to stop this construction and now that the suspicions are mostly cleared, they finished the construction within a day.
Moriya used the newly constructed Space gate to go back to the thunder god temple.
The Space gate near Sam's city was there for them to have easy access to the place so that they can keep watch over it and from the looks of it, there seemed to be too many encounters with Sam and the Space gate would be useful.
