Su Qingwan, a doctor of modern medicine, once traveled through time and became an abandoned concubine in the cold palace whose name was not found in the history books of the Dajing Dynasty. The beginning is hell mode: a broken house, half a bowl of rotten rice, plus a half-dead cheap emperor husband in the physical sense. Good news: The cold palace is quiet enough, no one is fighting or annoying. Bad news: You will really starve to death, die of illness, or be bullied to death by any eunuch.

Su Qingwan chewed melon seeds: I won't go, there are too many women in the harem, which will affect my career. The gloomy and paranoid seventh prince had red eyes: Sister, I want both the world and you. Su Qingwan waved her hand: Don't love me,
