Time passed this way for longer than what they all realized. Three days of training balanced with helping wherever they could.
The Terra city assistance had brought with them a lot of strong guards. They worked well with removing rubble. Not to mention the earth type beasts that came as their partners. Those earth type beasts were already experienced with removing large quantities of earth. Therefore, they sped up everything by quite a bit.
Beyond that, Terra City has always been a safe place to store a lot of food. They had needed to do so since they did not produce much on their own due to them living underground. That ensured that they had to trade for it very often. The results of that were massive storage areas of dried and otherwise saved food.
