In the twelfth lunar month of winter, Jiang, the head wife of Shangshu Mansion, committed suicide by hanging from a beam. Fourteen-year-old Jiang Tinglan knelt in the mourning hall, looking at the newlyweds standing beside her father and listening to their plot to marry her away to Xuzhou.
That night, she took the old dagger left by her mother and escaped from the red door.
She wants to become the best swordsman in the world - just so that one day she can seek justice with her own hands.
But she didn't expect that Jiang Hu would be involved in the family murder case at Zhujian Villa in her first step. A peerless sword and a last letter from the deposed prince implicated the "Three Kings Rebellion" eight years ago, and also revealed the truth behind his mother's death.
Along the way, she met a crazy sword-crazy master and a sweet friend as gentle as plum; some died for her, and some lived for her. When she finally stood in front of her enemy with both swords in hand, she suddenly understood——
The sharpest thing in the world is not the sword, but the human heart.
And she wants to live well for those who died
Purpose: From revenge for her mother to her family, country and world, a girl grows into a true knight in blood and fire
