This was indeed a shocking matter for him.
He had ran after goliath through extreme tiredness and exhaustion, even through death and beyond, that's how his achievement had unlocked.
Other achievements too.
Meeting Kronosia, the transmigration, in all of these moments that he had experienced, Arthur could proudly say that he didn't hurt a single soul.
The trials he had gone through, he had done all that without sacrificing a soul through his actions.
But now what.
"I unlocked an achievement by murdering." Arthur told himself as he looked at all the dead goblins around him.
He himself was standing on tens of these goblins.
Simply murdering five hundreds of these green guys had allowed him to unlock another achievement.
Arthur looked at the script of the Heaven's Eye and read the unlocked Achievement.
( Achievement Unlocked: Goblin Slayer! )
( Two passive stats have been unlocked! )
