Conquer the Nine Heavens

In a world where people are divided into four categories, untouchables, commoners, nobles, and saints, are there any kind of human beings, princes and generals? Let's see how I attack the Nine Heavens today and use their dirty and greedy blood and evil-filled souls to pay homage to the innocent souls of the so-called saints who have died over thousands of years!
