Not Easy.

The teams successfully built two barracks for themselves. Bother buildings were three-floor high and had enough space for the people to sleep and rest. They all had some education regarding civil structures and as Core formation cultivators they were smart enough to follow the instructions of the technicians who had a basic knowledge. 

The people slept contently yet the pain came too soon. They were all woken up harshly the next morning. The sun has not yet risen when You Xi Wang woke them all up. He had them freshen up and sit down facing the horizon to meditate. 

The purpose was to have them develop the habit to sleep to the bare minimum. They were all tired from the teleportation plus the heavy work for building the barrack. Thus they were all sleeping deeply. Another purpose was to make the people absorb the active spiritual energy.
