Can you recommend a fantasy novel?

I used to read it, but I haven't finished writing it yet. I want to continue reading it now, but I can't remember the name. The main character was originally an emperor. Later, he was sealed into a nearly collapsed underground tomb because of a power struggle (it seems to be so). A woman who liked him was also there. Later, the woman made him drink her blood, so the man escaped alive. I can't remember what happened. The main character changed very badly, but his appearance and physique were also changing. He slowly became a woman, and it seemed that he could also become a man again. He could also absorb the beauty of all the beautiful women he had seen. It was strange. He had a child with him and was hiding from some people. Those people seemed to be some kind of righteous envoy or something. They were specially used to deal with people like him who had obtained strange powers.
Who can tell me the name of this novel? Thank you very much.
Cry to death. It's a very interesting novel. It's not as perverted as you guys say. Although the main character has become a woman, she's actually living in another identity after rebirth.
It's not Extraordinary (I've been watching it, but there's no such thing as the protagonist changing his gender), it's not the Redbud Moon, it's not the Dream Space, and it's even more impossible for the Fantasy City. I forgot how many words it is. Hehe, I've already said what I remember. It seems to be four words.
The story is not modern

" I recommend the Myriad Realm Sword Sect. It tells the story of the myriad worlds and clans fighting for power. The protagonist uses a sword in his hand to interpret the legend that people yearn for. Please collect, recommend, and support me!
