In 2024, young policy researcher Chen Yue died suddenly and was reborn as an educated youth sent to the countryside in 1976. Relying on his precise grasp of historical trends and future knowledge, he started from saving a small village in the magnificent changes of the times, changed his destiny through the college entrance examination, elite education at Peking University, and worked hard at the grassroots level, and finally grew into a leader at the forefront of reform. The story runs through the great changes in Chinese society for nearly half a century, intertwined with the deep love across classes and complex political games with his first love Su Wanqing, as well as a core secret about "prophecy" and "choice". When he was in a high position to promote key reforms, "prophetic" accusations from the past pushed him into the abyss, and the only thing that could prove his innocence was the mathematical formula left by his lover.
