The Yan Dynasty was at its peak, the temples were undercurrents of power and power, and the people's daily necessities, food, rice, oil, and salt also had their own bitterness and absurdities. Due to an accidental murder, Qi Qiying, a commoner from a poor family, and Fan Qianhu, a city scoundrel, were involved in a conspiracy and power struggle between the powerful minister Zhu Zhanran and the down-and-out talented Han Silu. With the changing of times, refugee uprisings and competition among three parties, the fates of people in the temple and the public are intertwined, with sorrow and joy mixed together. Qi Qiying had to struggle to make a choice between absurdity and warmth, witness and write the absurdity of "Dayan", and ultimately lead history to a new situation, showing the brilliance of human nature and profound changes in society.
