Fairy? Be My Demon Slave Obediently

[Profit first + extremely evil protagonist + decisive killing + no system + female acquisition] "Senior brother, how about you lick my feet like a dog now? Should I consider letting you live?" Once upon a time, Mo Dingcang was the most dazzling chief genius of the Tianxuan Sword Sect, and he devoted everything he had to his fellow Taoist sister. In exchange, in order to cling to the powerful, she personally forged evidence and framed him as a demon traitor! On the karma-killing platform, he was deprived of his high-grade spiritual veins, suffered humiliation, and was dumped in a mass grave like garbage. Until that day, he opened his eyes from the pile of dead people and completely abandoned all hypocritical benevolence, justice and morality! The mysterious girl bestowed the "Magic Book of Heaven-Devouring Luck" to reshape the formless demonic veins that are superior to the emperor's! Male cultivator? Everything turns into blood food and nourishment for me to devour my cultivation and increase my strength! Female nun? Plant the Nether Slave Seal, forcibly rob your luck, and kneel down obediently to be my exclusive demon slave! In his new life, Mo Dingcang only believes in profit first! Any cold fairy, arrogant saint, or demonic witch, as long as they block my way, put a collar on me!
