After a few hours, Adam had recovered almost fully and although his HP, IESP and EESP were at full capacity, his body was still aching slightly and strained, needing time to recover.
However, he didn't have the luxury of time to recover and it wasn't his real body and merely the Dungeon Form, so Adam endured and didn't worry much about any backlash that he may suffer.
He repeated what he had done previously and stormed the Goblin Beast City, but from a different side of the city and began scouting it and memorising the area, while hunting beasts along the way.
After he was fatigued and drained and overwhelmed by the number of beasts that had converged on his location, Adam retreated in a similar way to how he had done so previously and would return to the same place to recover.
