I Use Demons to Pave the Way to Heaven

I was once a proud man, but I was framed by the sanctimonious leader, who ruined my cultivation and abandoned me on a cliff! They thought I was dead, but I came back in the Nine Nether Purgatory! Awaken all things to refine the demon map, the demons in the world are all my servants! At the beginning, you first refine a female ghost king in red to serve as a personal maid, and then join the Demon Suppressing Division as a junior captain. During the day, I slay demons and become the eagle dog of the imperial court; at night, I merge into ten thousand demons and become the Lord of the Netherworld! Tianjianmen, you wait! In the future, when I bring millions of demons to crush the sky, I will definitely demand that you hypocrites pay with blood! This novel and its characters are purely fictitious.
