Pang! Pang!
The bullets struck the Stone Cow from afar. They made the Stone Cow angry, but after repeated hits, its speed was slower than that of a snail. It couldn't come after Han Sen.
Han Sen was shooting from as far away as possible. The Stone Cow couldn't even see him, and even if it had been able to, it wouldn't have been able to go after him.
Earl class Spell weaponry could damage many things, but the bullets couldn't pierce the Stone Cow's body. Han Sen hadn't expected that they would be able to kill the Stone Cow, though. He kept firing bullets, imbued with the Turtle spell, to leave turtle markings across the Stone Cow's body to slow it.
At first, the Stone Cow was able to stomp to create its shockwaves. But as the turtle symbols piled across it, the Stone Cow looked like it was in slow motion. Its signature shockwave started to appear less and less frequently.
