The Demon King Just Wants to Practice, but the System Wants to Rectify the Abuse

No CP, strong female characters, fast travel, black humor, light comedy with group portraits, anti-abuse novels, healing and redemption (for the original heroine and the world of the original book) The Demon Lord is not a savior, he is just passing by to tear down the script; The system is not a tool, but a high-dimensional life that is ignorant of growth; The original heroine is no longer a victim, and everyone can save themselves and be reborn; The world is no longer locked by the plot, and everything can grow freely. Dongfang Canglan (a cultivator madman), the master of the Heavenly Demon Palace, has dominated the demon world for thousands of years and unified all demons. On the day of the tribulation, he was stabbed in the back by his henchmen, his soul was shattered, and his life was hanging by a thread. A system calling itself ZS-5703 appeared out of nowhere and said it could save her. Conditions: Go to four small worlds of sadistic stories to complete tasks. Dongfang Canglan: OK. The system originally bound her because the golden light on her soul fragment was thought to be a good person and the light of the righteous path in ten lifetimes. After binding, I took a look - good guy, magic cultivator. It's still the kind that reaches the top of the evil cultivator rankings. … The first world, substitute abuse. The second world is about palace fighting and abuse. The third world, a post-apocalyptic sadistic novel. The fourth world is a fairy tale of abuse. —— Every time a world is completed, the heroine of the sad novel awakens, and a new way of heaven is born in the novel world, which is no longer controlled by the plot of the original book. Dongfang Canglan repairs his soul and earns luck through the system. One wants to go home for revenge, and the other wants to fix his own bug.
