Returning to New Grenton

It has been a couple of weeks since Ren started hunting the monsters in the nearby areas. He nearly killed every living monster near his vicinity, and only left some of them. He was warned by the Adventurers Guild that he shouldn't kill every single monster, he must at least let some of them survive. It would seem that killing all the monsters was not a good thing since they weren't necessarily bad for humans as they use them as materials for weapons, armor, and everyday items. Some monsters were even used for creating medicine, while others were tamable beasts. 

At first, the Adventurers Guild thought that Ren would only subjugate the number of monsters written but he did not do so. Instead of simply killing the number of monsters requested, Ren kills most of every monster he sees and sells the parts to the guild and others to some merchants he knows.
