Chapter 331 - Killing Boss 

Using his supreme spiritual control technique he quickly uses his pure spiritual energy to coat his sword and approach that boss. 

Right now in front of Sam you can see that black scorpion. The black scorpion was already about to attack Sam but Sam also wasn't slow; he quickly attacked that black scorpion with his sword. His sword and the tail of that black scorpion clashed against each other. 

Previously Sam thought that he was able to damage the tail of that black scorpion but surprisingly it was not able to damage the tail of that black scorpion. Most likely this black scorpion was different from those other black scorpions and because of this he still wasn't able to damage it. 

Sam jumped away from that place. At this time the black scorpion was already releasing the flame poison from his tail. Even though Sam has confidence in his body, still he did not have any poison resistance technique, because of this he decided to avoid flame poison.
