I did not let the monster body fall; after taking my sword out of its chest, I touched it directly placed in my storage; there are quite high chances that its storage still has the reward it got from the Grand Palace, but it may also have not had anything.
As it may have received something like Knowledge crystal, which could be instantly used or sold away elsewhere, anything could have happened. I wanted to check its storage, but I couldnt.
First, it is a Grimm monsters storage, which I can't open, and the other thing is I am in the middle of the Battle.
After storing the body of the Grimm monster, I looked up and see there is a slight decrease in the number of people that are fighting above. When I was fighting with the Scarlet Werewolf, I saw a few bodies of Grimm monsters falling below.
Bang! Slice!...
After watching their blurry fights for a few seconds before I activated the mini blast and started killing again.
