The modern soul traveled through time and became Ye Cenxue, the Ninth Prince of Daliang. He became a hostage of Chu State for three years and suffered all kinds of humiliation. When the person is beheaded in the execution ground, the secret deduction system is activated, which can spy on the fate of the world and deduce the fate of the country. He deduced that Daliang would be destroyed by Chu in 87 days, and the traitor was actually his second uncle, Prime Minister Ye Wudao. Relying on predictions of good and bad luck through deduction, Ye Cen first crushed the Chu prince to establish his power in Qiu Lie, and then secretly wooed the Grand Tutor Zhang Jie to deal with the fighting forces in Chu. After returning to Beijing, he uncovered evidence of his second uncle's crimes of colluding with the enemy for food and colluding with the Chu army. He rescued his biological mother who was imprisoned and blind, and fought several deadly battles with treacherous ministers in the court. When the Chu army pressed heavily on the territory, Ye Cenxue used deductions to plan fire attacks and surprise attacks to disrupt the enemy's offensive, completely liquidate the traitorous officials, uncover the secrets of the ancient clan's secrets, single-handedly reverse the fate of the country, and rewrite the history of Kyushu.
