Li Ge was born into the Duke of Zhenguo's household and had a frail twin brother.
To preserve their hereditary title, she began switching identities with her brother when she was five.
She went to school in his place as a child, studied martial arts at Qing Shan Academy, and, as an adult, went on his blind dates.
But halfway through one such date, the border was plunged into war. The Liang army swept forward, capturing twelve cities in quick succession.
Called upon in a moment of crisis, she donned heavy armor, took up the tiger tally and her family's ancestral sword, and led fifty thousand troops to the front.
At the Battle of Shuo City, she burned her boats, fought against overwhelming odds, and battled the Liang army to the bitter end.
When the fighting was over, the Liang army had lost more than half its forces, while the entire army of twenty thousand, including Li Ge, had been wiped out...
Three months later, Li Ge, who should have died on the battlefield, opened her eyes in the dungeon of the Liang Crown Prince's palace.
Bandages covered her wounds, and iron shackles bound her hands and feet.
A long sword slid from its sheath, its tip pointing at her throat.
The person holding it was her archrival on the battlefield, the Crown Prince of Liang, and the God of War of Liang.
And also... her first love from years ago.
She leaned toward his sword and whispered, "He Chuan, don't you recognize me?"
