The alchemists were busy making potions with whatever materials they had.
Some adventurers among the crowd also want to explore the surrounding terrain that circled the castle and they also brought back many supplies for the group.
Food would be scarce and everyone didn't know how long they would have to stay in the castle to survive, so before there were any dangers, everyone collected as much food as possible.
The hustle and hustle lasted for a few hours until it was lunchtime, but everyone didn't eat a lot and just kept their belly half-full so that they could be prepared for any emergencies without feeling uncomfortable.
The entire group had prepared medicines, potions, food supplies, weapons of various types, and many other things needed to survive against any attack from either the beasts, the monsters or the abyss demons.
