May I ask if there is a book about the female protagonist being called Wei Xi, a Shangxian in her previous life, the male protagonist being the God of War, and the female protagonist's sister being Meng Po in her previous life. I have already read it three or four years ago. Do you know what the title is?

I read it three or four years ago. The female lead's name seemed to be Wei Xi, but I'm not too sure. The female lead was an immortal in her previous life, and the male lead was a god of war. The female lead's sister in her previous life was Meng Po. In her previous life, the female lead was a fairy guarding the immortal pool. The male lead was injured and met the female lead. Also, at the end, the male lead accompanied another fairy to the mortal world to experience the love tribulation in order to repay the debt of love. Although the female lead was heartbroken, she still accompanied him to the mortal world. In the end, they returned to the sky and were together. Recently, I want to review this novel again, but I don't remember the title. Please tell me if you have read it before. Had his friends really not seen it before? The male protagonist was injured in his previous life because he fought with the Demon Lord.
