I'm Not a Ruthless Person

Mo Bingxin was killed by her senior brother's enemy, and the Qiankun Pearl happened to be activated, and she survived in place of another person. At first she thought that she would not violate the rules and trade again, but in the end, it smelled so good! An ugly person can have a unique appearance by making a deal with the devil. People who are greedy for money can get a steady stream of money by making deals with the devil. Those who love power can gain power by making a deal with the devil. The devil can realize all people's wishes, talents, strength, money, and rights. These things that the world longs for will fall on her with a wave of her hand. However, it was always difficult for her to understand why some people always wanted to exchange love. This is the only thing that cannot be traded. Until that day, she met that boy. Even though she was trapped in darkness, like a demon, there was still a boy who reached out to her... But why do things always go off the rails... 1V1The weak female protagonist who was forced to become a demon/the real demon king and male protagonist disguised as a human boy.
