Seeking a novel, completed.

It was a novel that he had read in the past three to four years. It had already ended.
If the male lead was right, it was a demon. The female lead could not remember her identity.
However, the female lead seemed to be an immortal cultivator, if he remembered correctly.
It was very well written. At that time, he seemed to have seen it on the recommendation list of a certain website. This meant that this novel had been on the recommendation list and many people had read it at that time.
The female protagonist had given birth to a child for the male protagonist, but there was a misunderstanding later on. The child followed the male protagonist, and the female protagonist seemed to have disappeared?
Then, the female lead would come back and say,[This child doesn't seem to recognize her] and so on.
In the end, they were still together.
Although it was a standard novel, it was really an extraordinary novel.
I hope that readers with good memories can help me point it out.
Thank you very much.
PS: I have already read the usual classic Xianxia articles, so some familiar ones may not be. I hope everyone can help me out. Thank you!
