I'm urgently looking for an ancient fantasy romance novel!

The female lead's name had the character 'Su' while the male lead's name had the character 'Ming'(the male lead liked to dress in red). The female protagonist had a few disciples in her previous life, and the male protagonist was one of them. The female protagonist was killed by her disciple in her previous life (I still don't know which disciple or disciples killed the female protagonist). A few thousand years later, the female protagonist was reborn (she didn't remember what happened in her previous life, but in this life, I remember that she loved money very much). Her disciples had already become overlords. Later, the female protagonist met several disciples one after another, but none of them recognized her as their master. The male protagonist had once abducted the female protagonist to his city (the name of this city seemed to have the words 'night' and 'dark') for a period of time. He had also disguised himself as a woman to accompany the female protagonist to a sect to cultivate. If you have read this book, please give me the name of the book. I really like the real book. If you haven't read it, can you help me find it? Thank you, thank you, thank you.(Maybe I didn't describe it very well, please forgive me.)(ps, the male protagonist, the demon in red, was not a prince or a king. He was just a simple overlord who occupied a city. However, this city was very impressive. It was similar to a paradise. It was a little isolated from the world and it was very difficult to enter. As for the female lead, her original identity after her rebirth wasn't that impressive. I don't remember it very clearly. In short, after reading it, I know that this novel is really good. I belong to the kind of novel that is very bad at describing.)
