Su Yaoyao, the ninth most unpopular princess in the palace, saved the dying young eunuch A Yan in the snow. Ten years later, the little eunuch back then has become the powerful nine thousand-year-old Gu Xuanyin. Under his sinister appearance, he hides his obsession with her that has never changed - he crushes the flesh and blood of the bully for her, and uses his power to pave a road that is safe from wind and snow. Little does he know that she has already recognized him, and he hides an ambition that is colder than snow.
She was a "little white flower" who was bullied in everyone's eyes, but when he imprisoned her in his arms, his fingertips grasped the broken jade in his palm - it was the half piece of plum-patterned jade he had held ten years ago, and now it became her key to unlocking his defenses. He thought he could warm her up with his gentleness and paranoia, but he didn't know that every time she showed weakness and every time she catered to her, she was trying to grasp the power in his palm.
In the plot line, he eliminated dissidents for her step by step: seizing military power, removing the prince, and establishing a young emperor, but when he tampered with the imperial edict, he was willing to fall into the trap set by her; in the emotional line, he hid the bloody past and only wanted to be her loyal dog, but he did not know that her "heartbeat" was false and her "use" was true. Only the half of the candy cake that had been hidden for ten years was the snow in each other's hearts.
When the cry of her youngest son ascending the throne penetrated the hall, she handed over the poisoned wine with a smile and watched the light in his eyes shatter into dust. When the bead curtain fell, the blood stains on the dragon chair were still warm, just like the last time he held her hand before dying - he protected her with his life to reach the peak of power, but in the end he did not wait for her belated "sincerity".
