Ning Wanqing, a fourth-year medical student, died of overwork and traveled through time to become the 47th concubine of the Emperor of Zhao Kingdom - a fifth-grade concubine who is always present, with a monthly silver of five taels, thirty kilograms of charcoal, and a total belongings of thirty-two taels and seventy cents.
Without power, beauty is a talisman to death. She pretended to be ill, hid her clumsiness, donated all her savings to find a way out, and finally recommended herself as acting eldest princess and pro-Wei. On her wedding night, she stayed alone in an empty room. The Queen Mother gave her 360 palace rules, and the noble concubine regarded her as a thorn in her side.
But she has a system to help the world: save people and change their lives to accumulate merit, which can be exchanged for modern medicines and golden needles. Medical skills are her only weapon in this cannibal harem.
From abandoned concubine to medical concubine, from chess piece to chess player. In this world, she relies on the scalpel to win.
