The cycle

Since some guards and workers wouldn't be able to work, the group decided to help them. Since Rain could use earth magic, he was basically as useful as twenty workers, so the pace of the construction of the fortress wouldn't decrease. 

Usually, Rain wouldn't agree to do that kind of work since it went beyond the terms of the job. Still, since he got a bunch more magic crossbows and could make some coins selling a few of them, he decided to do that since he was in a good mood.

On the day the group began to prepare to head home, a new group of workers and guards arrived to take their place. It seemed that the higher-ups understood that the enemies were truly worried about that fortress, so it was better to keep the progress of the building from falling behind.
