This is a long story that spans palace intrigues and grassland wars. It tells the story of Mingxi, the eldest princess of Dayao who bears the blood feud of her family and country, and the entanglement between the tit-for-tat confrontation and the life-and-death dependence of Murong Lie, the Khan of Shuomo.
Mingxi has experienced court strife since she was a child, and the battle of Daiguo caused her to fall into a cold lake and lose her flesh and blood. From then on, she used a sharp blade as her armor and worked step by step in the whirlpool of power, just for revenge and protection. Murong Lie, who comes from the grassland, seems to be rough and unruly, but he has been patiently protecting Mingxi for many years - he is her rescuer in the desperate situation of the cold lake, the unexpected weakness in her plot, and the only warmth in her frozen heart.
From the swords and shadows in the capital to the vast stars of the grassland, the two are repeatedly pulled between hatred and love: she fights for the country, he is willing to sacrifice half of his country to protect her; she is trapped in the scars of the past and dare not indulge, but he melts the ice in her heart with his lifelong warmth. When the war between the two countries gradually started, and when the decision of life and death came, they realized that the so-called fate had already been determined at the first sight - it was each other's disaster and each other's salvation.
The story contains the magnificence of the war, the intrigues of the secret fight in the palace, and the deep love that spans life and death. In the end, all the edge is lost to the years, and all the pain blooms, leaving only a legend about love and protection. At the junction of the grassland and the Central Plains, as the begonia flowers bloom year after year, they will warm future generations.
