Interesting!
I thought when I looked at the four Grimm Monsters fighting against each other; the Grimm monsters rarely fight each other, especially those from the different tribes. They stay away from each other and rarely talk in between them.
These Grimm monsters are fighting at the very secluded spot in the valley; if not for me expanding my senses, I would not have been able to find them as this place is even more secluded than the place I set up my abode.
Feeling curious, I stealthily walked close to the Grimm Monsters while covering myself with the thick killing energy. As I got close to them, I was able to get a close look at their surroundings and look and felt even more curious.
They seemed to have dug quite a huge hole, and took out a small stone case; I could see that besides the huge hole, there is a small blasck case, on which signs of dirt could still be seen on it.
