Qin Jingyu, the seventh prince of Dajing, lost his mother at an early age and was taciturn. He was ridiculed as the "dumb prince" by the palace people and lived in the most remote Lengyuan of the East Palace. An unexpected look at each other during a heaven-sacrifice ceremony actually awakened his "heart mirror" power - the ability to see into the most secret thoughts of others. Underneath the prince's gentle and elegant appearance, there is a monstrous ambition to kill his father and usurp the throne; the sedative incense given by the concubine is actually a chronic poison that kills his biological mother; even the newlywed wife's cute smile hides a cold plan to collude with the prince and seize military power.
The deep palace is like a prison, with murderous intentions at every step. In silence, Qin Jingyu peeped into the human heart and ghosts. In a desperate situation, he contacted the secret organization "Yuwei" left behind by his mother and concubine, and gathered the old border troops. During the hunting season in Autumn, the prince colluded with the military governor of the northern border to launch a mutiny, intending to kill him. Qin Jingyu took advantage of his plan, killed him in the hunting ground, put down the rebellion, and was granted the title of King of Jing'an.
However, not long after the glory of victory, the prince's scream before his death revealed an even more shocking mystery of his life experience: his mother-in-law was actually an orphan from the previous dynasty! And he himself has an ancient bloodline that can subvert the world. The appearance of the mysterious guardian, the "Xuan" token organization coveting the bloodline, infiltrated into the capital, and the emperor's suspicion caused by the master's great achievements... A bigger storm is already brewing.
From the silent prince to the king of Jing'an, from the prisoner in the palace to the commander-in-chief of the northern border, Qin Jingyu holds the "heart mirror" in his hand and carries his bloodline. In the whirlpool of intrigue, hatred and protection, he embarks on a silent and thrilling counterattack.
