"Why didn't the three of you just take one mission together if you can complete it this quickly? Are you trying to make the lower-ranked adventurers go poor?" Illya asked them as she held her forehead.
"I thought they reproduce quickly," Maria said.
"They do, but, they won't be exposed when they reproduce. So how will the F-ranked adventurers go find them? Unless they go into the monster's habitat and get attacked by the entire species." Illya explained to Maria.
"Oh," Maria finally understood. If all the monsters go into reproduction, they will naturally all be together. This might even cause problems amongst a B-ranked adventurer
"Sigh, well whatever. I am just going to promote you all to D-ranked adventurers so you don't make the F-ranked adventurers go poor." Illya said as she asked them for their dog tags before giving them a new one which was a different color.
"Thanks~ It's pretty dark, so we'll go home now," Maria said.
