Please recommend a transmigration novel. It would be best if it was fast!

Sigh, I couldn't remember what the name was. I remember that I read this transmigration novel a long time ago. It was very good. I only remember some of the plot.
1. The female lead had transmigrated twice. The first time seemed to be her soul transmigrating. Then, after she died, her main body transmigrated back.
2. It was a country that did not exist in history. The male protagonist was the king of a country, the kind that was a little ruthless.
3. The female protagonist did not like the male protagonist very much because the male protagonist seemed to have forced her to kill her friend in order to get her, causing her to be misunderstood by everyone. In the end, she died of depression in the palace.
4. The second time she transmigrated, the first time was to the male protagonist. Then, that night, the father of the person the female protagonist liked died.
5. The female lead 'died' after that. In fact, she was 'beheaded' by the supporting male lead, but she was actually drugged and lost her memory! She was sent to the male protagonist's country, but the male protagonist…He did not know.
6. During her amnesia, the female protagonist gave birth to a boy who clung to the female protagonist.
7. Her friend had transmigrated with her for the second time and found her. It seemed like a man and a woman had both become officials?
8. He remembered that there was a plot where the male protagonist was bitten by a snake. The female protagonist had to fight for food with the other snakes to save him. Then, when someone came to save them, they saw both of them lying on the ground!
9. When the original body transmigrated back. When the female protagonist was about to be beheaded, the male protagonist was very calm at first. Because his sister was the empress dowager of this country, he asked his sister to save the female protagonist. However, he did not expect that the male protagonist's sister hated him because she married her to the old emperor of this country for the sake of the country's power. Therefore, she did not want the male protagonist to have everything go well. She personally fed the female protagonist poison at the beheading table. When the male protagonist saw this, he was very angry and sad. He wanted to jump down to save the female protagonist but was stopped by his guards. The male protagonist seemed to be shouting, I'm going to lose her forever... He even asked his guards or eunuchs to save the female protagonist.
10. When his soul transmigrated, the male protagonist was very ruthless. He defeated other people's countries and even turned one of the female protagonist's friends into a eunuch and a god-like figure into a male prostitute!
Sob, sob, sob, I can't do it even if I want to break my head.

Answer 1

I recommend " Arrogant Concubine: Your Highness, please have some self-respect." The protagonist is the leader of the assassin world. In one day, she transmigrated to become the deposed Empress of the Cold Palace of South Chu and married the idle king as her concubine. Watch her rampage in the palace, house, and power struggles in the other world. I hope you like my recommendation.😗
