In the end, Ryan endured doing nothing but summon skeletons for an entire week. However, as one would expect from someone who pretty much fought every single day against monsters in the last four months, Ryan got sick of it. To make things worse, he used that entire time to think of a way to eliminate all the slimes in that world, but he didn't find a better way to do it.
"Well, I guess it is time for plan B," Ryan got up and then said it while he was cleaning the dust from his clothes.
"I didn't think you have a plan B," Femradiel asked, surprised. "I am very surprised that you even managed to resist using it for so long."
"I am still trying to come up with plan B," Ryan said.
"So, that is why…" Femradiel said. "Anyway, I also underestimated this task. If you need some tips, I can offer some. Just like I can feel the concentration of mana due to the dungeons, I can also feel the concentration of mana in some places where monsters are agglomerated."
