More than a day had passed, and since I've obtained the Map from the Grimm Monster, and I continue on the things I set out to do.
There are too many Grimm Monsters in this area, at least three times more than found in the normal hunting grounds, and the powers of these Grimm Monsters are also very great.
They have the average strength of the Five Star Elite which is horrifying as it is just as average strength if one looks carefully they could find Six Star Silver Elite and Seven Star Silver every few minutes and Eight Star Silver Elites one to two times an hour and Nine Star Elite every few hours.
This is the level of powerhouses this area has, and this is not Mariana Hill; the Mariana hill is even more dangerous. According to the info the Guild has provided me, it is said that the average Strength of Grimm Monster in Mariana Hill is Seven Star Silver Elite, whereas here is Five Star Silver Elite.
