Once time traveled, the two sisters met in a different world; the power of the house was controlled by the system; the beautiful world was in Su's hands.
Modern best friends Lin Weiyu and Su Qing accidentally travel to the Dasheng Dynasty that has never been recorded in history due to a mysterious ancient book. One of them became the cold-eyed concubine Chu Weiyu in the Shangshu Mansion, and the other became the free-spirited legitimate daughter Zhao Qing'er in the General's Mansion. The high walls and deep courtyards prevent the sisterhood from being separated; when time and space change, they are not fighting alone - along with them are their own mysterious systems.
Chu Weiyu is responsible for the "Civilization Advancement System" and needs to spread modern knowledge in the world and promote the progress of civilization in order to gain a foothold; Zhao Qing'er holds the "Artisan Workshop System", and all her whims and wonderful ideas can be turned into physical objects, and only by creating inventions can the future be unlocked.
Inside the house gate, there is a turbulent undercurrent. Their aunts are making things difficult for them, and their sisters are at odds with each other. They need to be cautious, step by step, and use modern wisdom to resolve ancient crises. Outside the court, the storm is rising. Bit by bit, they brought here ideas and technologies that transcended the times: improving agricultural tools, innovating craftsmanship, setting up girls' schools, preventing and controlling plagues...
From the initial struggle to survive to the mutual support and tacit cooperation, they not only have to fight wits and courage in the small space in the back house, but also want to use their hands to change this backward era bit by bit and provide a peaceful and happy life for the people of the world.
Let's see how this pair of modern best friends go hand in hand in this strange dynasty, use knowledge and systems to mediate among wealthy families, and gallop in the wider world, and finally compose a song of their own prosperous age. They not only find the right husband, but also achieve a life without regrets.
