A "Mystery of Destiny" appears in the Dayong Dynasty. Those involved need to complete various strange tasks, and those who fail will suffer unknown punishments. Shen Yan, a junior official, accidentally entered the game. He has no golden fingers or special skills and just wants to survive. But the tasks are intertwined, involving royal secrets and conspiracy, making it difficult to distinguish whether the people around you are friends or foes. He was forced to grope in the fog of suspense, and with the mentality of "lay down and don't bother", he repeatedly encountered the truth of the mystery by mistake in desperate situations, and even discovered that this so-called "game" was actually closely related to the rise and fall of the dynasty.
