Female General and Eldest Princess

In order to survive in troubled times, to avenge her loved ones, and to seek justice for the 118 people who died in her village, Lin Wanyue took the identity of Lin Feixing, her younger twin brother, to join the army, resolving to kill the all Huns in the world.
The queen died in the court, leaving the sixteen-year-old princess and eight-year-old prince to depend on each other for survival.
Several princes who were older than the prince coveted the throne, and the status of the two siblings was at stake.
