Chapter 308 - Killing Goblin commanders 

2 hours later,

Right now Sam was fighting those goblin commanders. He already killed tho se Goblin captains and right now he wanted to finish all these Goblin commanders. Killing those gobbing captains did not take him that much time, he only needed 1 hour to completely kill all those Goblin captains but right now while he was fighting those Goblin commanders it became very tough for him to fight them. Compared to the Goblin captains the defense of these Goblin commanders also increased. So you can say that to kill them he almost needed to use 70% to 80% of his spiritual energy to sharpen his sword. Because of this, it takes him this much time to kill all those Goblin commanders.
