When Su Qingyan, a modern girl, was sorting out her grandmother's belongings, she touched an ancient mirror with a double-sided phoenix pattern. She was suddenly hit by an earthquake and was sucked into the whirlpool in the mirror. When she woke up, she found that she had become "Shen Weiwan", a concubine in the Ministry of Rites of the Dajing Dynasty, and was being sent to the palace to participate in the draft. The original owner committed suicide by taking medicine because she did not want to enter the palace, and Su Qingyan took over the body by accident.
