Su Qingyuan, the queen of the modern workplace, died suddenly while staying up late to revise her plan. When she opened her eyes, she transformed into Shen Weilan, the abandoned concubine of the Yin Dynasty who was thrown into the cold palace. The original owner was from a humble background, unfavored and powerless. He was deprived of water and food for offending a noble concubine, and was taken over by her when he was about to die. There is no golden finger or plug-in. Su Qingyuan relies on the high emotional intelligence, strong logic and ruthless skills she has learned in the modern workplace to make a living in the harem that eats people without spitting out their bones: she uncovers poisonous schemes and rebels against the generals, uses the opportunity to slap arrogant concubines in the face, uses workplace negotiation skills to resolve crises, relies on accurate identification of people to win over allies, and even manages the emperor as a "big customer". From abandoning concubines in the cold palace to favoring the harem alone, from being slaughtered by others to taking charge of the sixth palace, Su Qingyuan used her strength to prove that palace battles are not about family background or luck, but about IQ, mentality, and structure! When those who had bullied her fell one after another, and when the indifferent emperor had his heart set on her, Su Qingyuan stood at the top of power and sneered: Harem? It's just a "big company" that needs to be run carefully, and she is the best CEO!
