Upon hearing the thuds that came from 4 different directions, all 5 humanoid demons, including the leader that had almost had his hands on the bear's soul, stopped whatever they were doing and they all went into hyper-focus mode.
And because of that, All five of them each looked in the direction of the thuds almost simultaneously, making them able to see the 4 head-sized wooden balls that had appeared out of nowhere.
The wooden balls looked inconspicuous enough as they even had a similar color to the tree trunks and roots that could be found all around the area.
However, the reason the group of humanoid demons was able to notice them so fast was because there were glowing demonic runes on the surface of the wooden balls that certainly caught everyone's attention even if they didn't try to actively search for the source of the noise that they heard.
