In the eighteenth year of Hongwu's reign, Zhang Yu, an expert in criminal psychology at the police academy, opened his eyes and became the son of a prisoner implicated in the "Empty Seal Case".
In order to survive, he purged himself into the palace and became a eunuch at the bottom of the inner study hall.
This year, Zhu Yuanzhang's butcher knife had just been raised, the bloody storm of Hu Weiyong's case had not yet dissipated, and everyone in the Ming Dynasty officialdom was in danger.
And he controls everyone's outcome.
When Mao Xiang, the commander of the Jin Yiwei, discovered that this humble little eunuch could accurately draw a portrait of a prisoner through a footprint and a confession, a blood-stained embroidered spring knife was handed to him.
"Your Majesty wants a good dog."
Zhang Yu knelt down to receive the knife, but there was another account hidden in his heart.
He knows who will die, who deserves to live, and who will rule the world.
In this imperial city where the generals, ministers and princes were like ants, he decided to become a chess player step by step from a chess piece.
