Beicheng, an important military and political center, was guarded by three generations of the Shen family. Shen Heng, thirty-five years old, has a scar at the end of his left eyebrow, the mark left by an assassination seven years ago. Before he died, the assassin said: "You think you are playing chess, but in fact you are also a chess piece." He thought about this sentence for seven years.
In Nancheng, merchants gathered, and Suji Silk Shop was the sole proprietor. Su Jin is twenty-eight years old. Her parents died fifteen years ago. She supports the family business by herself and secretly investigates the whereabouts of her enemy Zhou Tong.
An arms case involved two cities and two people in the same chess game. Governor Jiang's plan, Marquis Dongchuan's scheme, the fifth prince's ambition - everyone is playing chess, and everyone is a pawn.
From temptation to trust, from use to sincerity. The assassination at the Autumn Defense Ceremony, the galloping horses on New Year's Eve, and the life and death of the capital prison. When Shen Heng withdrew from Marquis Dongchuan's marriage and told her, "Don't be a partner - do something else", he finally understood: In this cannibalistic chess game, there is one more thing that can be done with sincerity.
Those who died have paid the price; those who are alive can finally stand side by side on the Quanguan Tower in the evening many years later, looking at the lights of thousands of families in the distance.
The two cities are separated by three hundred miles of official roads. Two people, starting from temptation and ending with sincerity.
