Conqueror's Road

I came, I saw, I conquered. There is no pure justice and evil in this world. Any intelligent race stands in different angles and fights for the survival of the fittest for their dreams. Even God is the same. Can believers of the Holy Light embrace darkness, and can good wisdom be used for evil? From a large national or even racial level, war is just a continuation of politics, and aggression can also be through economics and culture. See how the protagonist grows from a kind-hearted orphan to a famous master in all worlds. [Dedicated to those born in the 1980s, there is no reason for fantasy to end]
