Ouyang Yao, a war-weary scholar who was beheaded at the age of 28 in his previous life, was reborn at the age of 55 in exchange for his remaining life. He went from a child prodigy to an emperor, but was devoured by the fear of death at the peak of his power. Finally, on the night of his 55th birthday, he was assassinated by the illegitimate son Ouyang Rui. Ouyang Rui was executed by the prince Ouyang Yu for the crime of "regicide", completing the tragic cycle of "the reborn being reborn and being reborn."
Ouyang Yu created a prosperous age after ascending to the throne, but at the age of 45, he discovered the hourglass curse left by his father. As he approaches the age of 55, he reveals the ultimate truth: the so-called curse is actually the eternal revenge of the previous dynasty's evil spirit on the hereditary power of the emperor.
In the end, Ouyang Yu chose the third path: smashing the imperial seal in public, abolishing the imperial system, and switching to cabinet co-governance. In order to end the thousand-year imperial power, at the same time let his father rest in peace, dissipate the resentful spirit, and break all reincarnations. The empty dragon chair and the still hourglass became the last relics of the old era.
