You take on two husbands, I'll turn around and marry the tyrant and rule the world.

Double rebirth + palace intrigue + exclusive favor + sober awareness
Chu Nianci and her half-sister Chu Shunqing were both reborn.
In his previous life, Lin Jingrui, the heir of the Marquis of Chengen, married two sisters under the pretext of inheriting the lineage of both families.
Chu Nianci suffered a hard life, was slandered for having an affair, had her dowry stolen, and was eventually poisoned to death by her mother-in-law. Chu Shunqing killed his sister's child, and although he was favored for a time, he was eventually driven out of the mansion.
When I opened my eyes again, I was back on the eve of my wedding.
Chu Nianci saw through it all: her husband was heartless and ungrateful, her parents-in-law were vicious and greedy, and her younger brother-in-law and sister-in-law were cruel. The Lin family was a den of wolves and tigers.
She will never repeat the same mistake.
Chu Shunqing remained obstinate, believing that Lin Lang had feelings for her and that her sister was the one hindering her. She came to drive her sister away, hoping to reclaim her position as the eldest daughter-in-law.
Chu Nianci decided to play along, allowing Lin Jingrui, his good brother, and Chu Shunqing to "reunite as a family."
On the night of the housewarming party, a beautiful scene of catching someone cheating unfolded.
She then took advantage of Chu Shunqing's jealousy and turned around to marry into the palace.
Since men are unreliable, it's better to fight for power.
They don't seek sincerity, only wealth and glory; they don't seek loyal friends, only pleasure.
The emperor was handsome but sickly, and she possessed medical skills.
The palace maids were snobbish and greedy, and she had a huge dowry.
The Empress Dowager is cunning and scheming, the Empress appears kind but is wicked at heart, and the Consort Shu is arrogant and domineering...
She has ten years of experience in palace intrigue, and she takes down every single one of them.
But the way that peerless young emperor looked at her... something was gradually getting strange.
