Disciple
Rupurn is frustrated and rightfully so, he is being harassed by someone of lower cultivation than him, and that someone happened to be a person he wants to kill with all he got.
The injury on the leg is way too much. He was too stupid and too angry to realize that Sam had the strength to deal the leg this much damage and only focused on attacking him. Now he is running with all his might to dodge the massive barrage of small energy bullets.
These bullets are only as big as marbles and they are coming at a rapid pace that made him feel like he was standing in the hail storm of energy bullets.
It took some time for him to adjust to that and he once again started going after Sam.
By now, Sam who didn't have to move around for a while took three potions to recover from the injuries and the exhaustion.
