Cthulhu Cultivation, I Am the World-Destroying Goblin

I traveled through time and became a goblin, or a subspecies of goblin produced by the cross between a general goblin and an orc. This is not the saddest thing. It was not until I found that my tribe was playing with the poor female knight in the cave that I could only dance with guns and sticks outside, that I felt my humbleness. Ahhhh! I want to destroy the world! Then, I got this world-destroying system. But why does this system smell so bad?
