Shen Qingxian's life came to an abrupt end the day his family was wiped out. Since then, the daughter of the former Taifu has died, and the only survivor is a maid named "Jin Se" who lives next to the seventh prince Murong Yi in the cold palace.
She came with a blood feud and carefully weaved a gentle web. She wanted to train him to be the sharpest blade to help her kill her enemies and stir up this turbulent world. And the prince who seemed to be weak, decadent, and independent from the world was the perfect chess piece she chose.
She taught him tactics, treated his illnesses, and depended on him for life. She thought everything was under control, until the night of the palace coup, when he fought bloody battles for her, killed his brother to seize the throne, and stepped on the Nine-Five-Year Master on the bones.
He offered her the blood-stained country as a betrothal, and promised her the position of queen, but his eyes were filled with paranoia and madness that she had never seen before: "This world is yours, and you are mine."
However, when the bloody curtain of the truth about the family's annihilation was lifted layer by layer, she was shocked to discover that the mother clan that supported him to the peak of power was one of the driving forces that pushed her family into the abyss.
Love and hate collided fiercely in her chest, and her family and country's justice and sincerity tore her apart inch by inch. At that time, she was the chess player and he was the middle piece of the game; now, he has become the tyrant who controls everything, but she has become the most precious prison bird in his golden cage.
When the sharp blade in his hand finally pointed at the chest where he had promised his whole life, in this game of chess in the name of love, did she win the world, or did he lose her?
There are fifty strings of Jinse for no reason, each string and one column reminds me of my good years. In this game that started with lies and played with sincerity, in the end, will we go to hell together, or will we be able to find the first moonlight in the cold palace that year?
