Release the Devil's Guilt

A skinny, ugly sin slave died in the Demon King's Palace. I heard that he was tortured by the Demon King for several years before he burped. No one knows that the sin slave once had the appearance that all living beings yearn for, a pleasant and beautiful time, and a husband who loved her dearly. I only heard that she was cunning and insidious. Not only did she kill the Demon King's only son, but she also designed to make the Demon King almost die. Crushing her bones and raising ashes would not be enough to atone for her crime. The death of a sin slave is not a big deal, but the devil tried his best and never heard a scream from the sin slave. Now that he died like this, it could not relieve the hatred in the devil's heart. Therefore, the devil personally went to the ghost world to ask for someone to save her and then let her atone for her sins... The IQs of the male and female protagonists are both online. The scheming, murderous, decisive, arrogant and beautiful villain, the Demon King, VS the innocent and sinister in the early stage, the clever, domineering and little ancestral goddess in the later stage. In this life, she released two people who should not be released, once accidentally and once unintentionally!
