After the Anshi Rebellion, an unknown body suspected to be a "prince" was found in the western suburbs of Chang'an, which shocked the government and the public. Lin Zhong, a secretary-provincial scholar who died unjustly in his previous life, was reborn before the case occurred. With the memories of his previous life and the half-volume of the late emperor's edict left by his father, he was determined to uncover the truth. The emperor, the prince, the eunuchs and the prime minister started a fierce game around the case, and Lin Zhong was selected as a pawn to investigate the case. He got acquainted with the orphan girl from Jiangmen who lived in the market and was pregnant with half a tiger talisman. The two of them depended on each other from temptation to life and death. Lin Zhong used his past life memories to reveal step by step the concealed palace secrets before and after the Anshi Rebellion, while at the same time avenging the enemies who betrayed him in his previous life. In the arena of power, he must carefully maneuver to protect the people he cherishes while avoiding repeating the mistakes of his past life, and ultimately uncover the truth that could shake the foundation of the empire.
