Lin Yanqiu was originally a shadow that had never been mentioned in "A Dream of Red Mansions" - she was the concubine born to Jia Min as a dowry in order to perpetuate the Lin family's legacy. She had been raised under Jia Min's lap since she was a baby, and she was nominally the same as his legitimate daughter. Others only know that she is the eldest lady of the Lin family, but they don't know that she has memories from another world hidden deep in her soul, and she also has a mysterious system that can sign in at a specific place.
When the gears of fate slowly turned, sister Lin Daiyu was born, the olive branch of the Jia family was quietly handed over, and the prosperity and decadence of the Grand View Garden gradually spread, Lin Yanqiu knew that this feast would eventually come to an end. Relying on the foresight, skills and wealth brought by the sign-in system, she worked step by step: she learned the way of survival of an aristocratic family under Jia Min's knees, got a glimpse of the secrets of officialdom in Lin Ruhai's study, secretly made connections when she entered Jia's house in Jinling, and stayed awake when she watched Bao Dai fall deeply in love. She not only wants to protect her mother Jia Min's health, but also wants to protect her younger sister Daiyu Zhouquan. She also wants to earn a way out for herself in this treacherous house and the conflict between the aristocratic family. This is the story of a concubine who borrowed the power of the system to change her destiny against the odds in the troubled times of the Red Mansion, and blossomed out of the dust.
