My Vessel Is a Saint

The demon king Asmodeus died for a thousand years and was awakened by a girl with his blood. When she woke up, she realized that her soul was trapped in her body and couldn't get out. She was too weak, too weak to bear his strength. He was nestled inside her, watching her being bullied, ignored, and living like a transparent person. He smiled. Weak? It doesn't matter. Here he comes. Her face began to become beautiful and her body began to become stronger. He dealt with those who bullied her one by one. An exorcist sent by the Holy See? He took over the body and made the other person crawl out on his knees with just one word. The old demon tribe came to test? He unleashed pressure to remind them who was the king. She went from a weed on the roadside to someone everyone looked up to. She thought he was a golden finger, an opportunity given by God. But she didn't know that after the Demon King's death a thousand years ago, her arrival was planned by him himself. Her bloodline, her birthday, and the day she came to the ruins were all planned by him. She was his chosen vessel, the first step in his revenge. Later someone asked her: "What is your relationship with the devil?" Before she could speak, he formed a shadow and put his arm around her shoulders: "She is mine. Body and soul. Any opinions?"
