Rebirth of the Stupid Third Miss of the Prime Minister's Mansion

Surumeng spent thirteen years in a state of confusion in her previous life, and only woke up before she died, but it seemed that everything was still too late. Making a life-and-death contract, she returned to a time before everything happened. In a new life, the third lady of the prime minister's house must protect her second sister, support her eldest brother, defeat her scumbag father and vicious eldest sister, and repay the kindness of the general in her previous life. But... What about being the sister we agreed to be? General, why are you going back on your word?
