Su Yunjin, a top modern agent, died unexpectedly during a mission. Once her soul traveled to the Liang Dynasty, she accidentally married into the palace and became the princess of Xiao Yi, who everyone said was destined to die soon.
Everyone in the government and the public agreed that the King of Zhenbei, who had suffered from serious illness on the battlefield and had been recuperating behind closed doors for many years, was running out of time. Under the walls of the palace, there were hidden lines planted by others. All forces were eyeing the power of the palace, and undercurrents were always surging.
Others thought that by marrying into the palace, she would become a widow, and that she would be trapped in a deep house and spend the rest of her life carelessly. But Su Yunjin has the unique acumen and decisiveness of an agent in her bones, and she can see through Xiao Yi's frail appearance at a glance that there is a bottomless city hidden under it.
She put away her sharp edge and planned step by step in the deep palace. While helping the husband beside her to eliminate the murderous intentions in the court and stirring up the turbulent chess game in Daliang, she also cleared away the layers of fog to explore the secrets that Daliang had buried for many years. The two relied on each other in the turbulent court, and worked side by side to overcome all obstacles in the way, and finally reached the supreme throne that no one dared to imagine.
