The Prince Xian's Mansion welcomes a concubine. No one knows that she is the secret guard "Shadow Seven" carefully placed by the former Crown Prince. She is responsible for stealing secrets and is convinced that Prince Xiao Heng is a hypocrite who is bringing harm to the country.
The years in the royal palace subvert the perception: the virtuous king is worried about farming, and the princess cares about the world, which is completely different from the evil deeds instilled by the prince. The barren fields reflect hypocrisy and lies, and the old wounds in the armor tell the truth about saving the people. Faith collapsed and Dark Blade was confused.
The plague breaks out suddenly, the prince is dying, and the princess is pregnant. In a desperate situation, the concubine "Xizuo" imprisoned herself in the epidemic room and vowed to live and die with her young son! She fought for her life with the secret skills of the secret guard, and even secretly improved grain varieties, and helped the wise king collect evidence of the prince's crime.
Shocking reversal, the dust has settled. The Xianwang couple had already understood her identity, but they gave her tolerance and new life. Love secretly arises, a daughter is born, and light seems within reach. However, the fate of "the secret guard betraying his master" follows him like a shadow. When everyone thought that all the hardships would come to an end, the newly promoted mother was in the Nuan Pavilion. Did she choose a cold end? Still trying... Who is she? Why betrayal? And why go to a dead end when there is hope? A royal palace secret about loyalty, betrayal, awakening and self-destruction, slowly unfolding in the smoke of war.
