Yang Ji was soul-transmigrated into the Sui Dynasty and born a Prince of Suian Commandery. In just six months, he watched his father, Yang Shuang, who had burned down the Turks' sacred mountain, rise to become Prince Weizhao, and then took the title of Prince Wei himself.
But after reaching adulthood, he discovered that Gao Jiong, whose fate was to fall from power, was destined to become his father-in-law.
At first, Yang Ji only wanted to get rid of Gao Jiong, but things turned out to be far more complicated than he had imagined.
