Looking for two romance novels

These two books were from a long time ago, at least five or six years ago.
[The first book: I only remember that the female protagonist finally found out that she was some Snow Concubine (I think it was called this, but I'm not sure). Anyway, I don't remember why at the beginning, but she was brought home by the male protagonist. It seems to be a place called Sky Eagle Castle, Flying Eagle Castle, or Cold Eagle Castle.] Then, he tied a bell to the female lead. What left a deep impression was that once, the female lead's back was injured and she could only lie on the bed to recuperate. Her back was dry, but she didn't feel cold at all because she was, or was, her predecessor, Concubine Snow. There was also another time when she was strolling on the street and the well water sprayed out. Anyway, she found out that she was Concubine Xue in the end.
[Second book: It's also a little fantastical. It seems to be a series. The male leads in the series are all gifted. I'm not sure if it's a series or not, but in the book I read, the male lead can control fire.] At first, he rejected the female lead because of his special identity, but later he confessed to the female lead.
Please, thank you.
The first book was from ancient times, and the second was from modern times. The male lead seemed to be related to some Vermilion Bird, but he was not sure.
"Also, I didn't read it online at that time. Actually, it's been almost ten years now. At that time, the conditions weren't so good. At that time, he was still reading the popular pirated romance novels from Taiwan.
