Traveling Alone
Squelching noises filled the Dungeon for multiple kilometers as William and the others dealt with the Quake Slimes one by one. Their oozing figure and high resistance to most attacks made them difficult to kill, but their ability to attack was quite pathetic.

The best part of the 11th floor was that each Quake Slime dropped two Quake Dungeon Gems instead of one. In a matter of two hours, the group had collected a total of over six hundred Gems, which would be split equally.
