Rob was a mid-stage earth spirit enhancer, hence his [Stone Skin] was strong enough to resist the three-headed creature's paws and bites. However, it didn't mean that he didn't feel any pain. On the contrary, the ex-football player was hurting all over his body as he continued to dodge and handle the attacks the huge three headed monster threw at him.
The man gave his best to really attract the monster's attention. But in the end, he was still a human who didn't have inexhaustible stamina. His body gradually became slower as he gasped for breath, wounds began to appear on his body.
