189 Sacred-blood Ghost Butterfly

Han Sen was startled and quickly dodged the boomerang. The boomerang’s sharp edge cut into the rock behind him and burst into blue flames.

"S*#t!" Han Sen was stunned by the power of a primitive ghost butterfly boomerang. If he could get a mutant one, it would probably even be a great threat to sacred-blood creatures.

The shape of the boomerang was quite unique, and he must learn some special methods to use it.

Han Sen was very intrigued. There were ghost butterflies in the cave and he could easily gain a lot of beast soul boomerangs if he killed all he saw on his way.

As for the danger, he was not worried at all. If he shot the arrows hidden in the underground river, he could make a dive whenever it seemed dangerous.

And he also had his mutant black barracuda mount and did not need to swim and dive himself. The ghost flame butterflies could not harm him anyway.
