During the reign of Yonghe, all the people in Zhen'anhou Mansion were executed.
Six-year-old Gu Yan was rescued by his former subordinates and hid in the Jianghu, using the nickname "Zi Shu" and sharpening his sword in the dark for eleven years.
Eleven years later, a secret letter from Uncle Dumb recalled him to the capital. He stepped into Prince Yu's Mansion, used chess as a matchmaker, and knocked on the door of Prince Che's Mansion. He thought he was playing a game of revenge alone——
Little did he know that from the moment he stepped into the capital, he had been put on someone else's chessboard.
King Yu said "I won't fight", but he kept secretly moving every step. Liu Cheng is the enemy on the surface, but the real one holds his hand on the dragon throne. Liu Cheng's daughter Liu Qingwan was the only surprise in Gu Yan's game - they were strangers who met by chance when they were young. When they reunited twelve years later, she didn't know that he was her father-killer.
When the truth was peeled off layer by layer, and when the chess game for the inheritance gradually became clear, he finally understood: the price of revenge has never been death.
It's to live and then watch all your loved ones leave one by one.
