Xie Zhaoyue, an orphan girl from a poor family, was abandoned in a deep palace and a cold courtyard. Carrying the memory of her past life, she endured it for ten years and finally ascended the throne as emperor on the day when the imperial power changed. All the civil and military officials in the court knelt down and shouted "Your Majesty", but Chu Siwu, the general who ruled the country, stood at the foot of the steps, his eyes as cold as frost, and the sword in his hand was not sheathed. She knew that he hated her for seizing power, but she didn't know that he had been quietly guarding her in the dark since she was reborn. When the undercurrent in the court surges and the border war breaks out again, this pair of men and women, who are closely related to each other in life and death but are suspicious of each other, will finally unveil a shocking situation that spans two generations between the dragon chair and the military talisman.
