One Hand Is Medicine, the Other Is Poison, the Abandoned Daughter Returns and Kills Her Like Crazy

[House Fight + Machiavellian Strategy] When she was four years old, Chu Yujing was abandoned in Jackdaw Ridge by her father who loved and valued power. A desperate place where no birds can cross and no living person can escape! Thirteen years later. A green-topped carriage dragged her back from hell, not to admit her kinship and atone for her sins, but to ask her to marry her twin sister as a stepping stone for the Chu family to cling to power and stabilize their family! Stepping into the Chu Mansion again, she is no longer an ant that can be trampled on, but a life-threatening judge who holds poisonous tactics and can decide life and death! The ambitious prince, the arrogant and cruel princess, the vicious sisters, the indifferent blood relatives, and the nobles of the aristocratic families who add insult to injury... She will not forgive anyone who stepped her into the quagmire and treated her as a fool! Wash blood with blood, fight for life with life! Tear down the scumbag sister in the back house and fight against the powerful in the court! In this unpredictable whirlpool, she must find a way out and overturn this rotten world! Is King Ling's solicitation a trap? Is there a secret behind King Yi's aid? There is no bottom line in the use of loved ones? After all these mechanisms are exhausted—— Who are the chess pieces? And who is the real chess player?
