The heroine transmigrates into the daughter of Qin Shi Huang, who died of illness while he was on tour.
"It is said that Qin Shi Huang toured the eastern lands, where his daughter died and was buried." Records of the World from the Taiping Era
After thinking it over, the heroine resolutely conceals her identity, disguises herself, and heads for Beijun.
The Qin state's fastest and best path to advancement, the military merit rank system, is still in effect in Shangjun on the northern frontier and among the Baiyue tribes in the south.
Rather than be an obscure princess in the history books, she'd rather make a name for herself.
She quickly switches her quest from being an unloved princess confined to the inner palace to fighting the Xiongnu in the northern lands.
To the First Emperor, a peerless general has appeared in the north.
In the first year, urgent news arrives from the north: a young commander led his troops in a night raid on the Right Wise King's camp, capturing more than ten Xiongnu nobles and tens of thousands of their people.
In the second year, the lands south of the Yellow River are reclaimed, and the Xiongnu are driven north of the Yin Mountains. Jiuyuan Commandery is established.
In the third year, she launches a thousand-mile raid on the Xiongnu's sacred ground, forcing the Chanyu to flee under cover of night. The Qin Empire's territory expands a thousand li to the north, a trade route is opened, and the northern lands prosper from then on.
The First Emperor knows that this peerless general is his own daughter. He wonders, why did she have to be born a girl?
By the fourth year, the northern trade routes that once ran through the land are bustling and prosperous. The taxes from the north alone amount to half of the central government's revenue.
When the First Emperor realizes that his daughter has her eye on the throne, and hears her say, "A daughter can have her father's heroic courage, too," his feelings are complicated.
