A soul torn apart by its own wisdom and past responsibilities. Before losing his memory, he was a ruthless chess player who carried his family and country on his back and believed that "the world is a game"; after losing his memory, he was forced to re-examine the world and human nature with a blank body, and instead got closer to the true nature of "Tao". His growth is a transformation from a "chess player" to a "game observer", and finally to a "legislator".
A genius who grew up in the cold imperial power and emotional desert. He is proficient in rules and good at manipulating people's hearts, but he deeply hates the ignorance and hypocrisy around him. Deep in his soul, there is a hunger for "truth" and "equivalence." Shen Buyan's appearance is not only the most dangerous variable in the chess game, but also the only mirror that reflects the emptiness in his soul.
The amnesiac prime minister forms an alliance with the prince of an enemy country to seize power. Each time he breaks a game, he regains a piece of his memory and discovers that they are old enemies and confidants.
