Lin Xiao, a 28-year-old modern Internet "cow horse" operator, in a life overwhelmed by KPIs and overtime, the only solace is to study food.

When she first entered the palace, she faced the dilemma of being deprived of food by servants and in a difficult situation. The modern "survival instinct" made her decide to use food as a weapon to break the situation.
