Gu Qingci, the modern internal audit manager, once traveled through time and became a useless concubine waiting to die in the cold palace. The poisoned wine was put to her lips, but she saw a mistake in the account book of the Royal Pharmacy, and she gave herself a three-day chance to survive. False edicts, poison gaps, and old grievances in the palace surfaced one after another. The young emperor Xiao Yan watched with cold eyes, but he had to use her hands to tear apart the shady story of money and power in the inner court. Others rely on tears to win favor, but she relies on evidence to check accounts; others rely on grace to survive, but she insists on investigating bad debts until the light of day. In the end, Feifei entered the game with a green pen and walked from the cold palace to the court. She checked the accounts, took her life, and also the power of the world.
