No can do

Lanqueas was located at the west of the Huring Continent, so the country Rean and Roan arrived at was obviously at the east border of Lanqueas. It made sense that the war between regions was more dreadful at the west border of the region they were in at the moment, Vigal. 

Rean and Roan were then given a day to prepare before they got teleported to the war zone on the west side. It's not that the army was being thoughtful, but that the teleport formation only activated once per week. It happened that it would be activated once again tomorrow.

Rean and Roan didn't have much to do in that place, so they simply cultivated in a corner, waiting for the day to pass. It was quite unfortunate that they couldn't bring Rank Three Divine Stones out as its Divine Energy would catch too much attention. Then again, Celis and Kentucky were already using it in the Dimensional Realm.
