After a decade-long war, the empires began to recuperate.
When preparing to retreat, Duke Nanchen of the Cang Ao Empire discovered a girl who looked about eleven or twelve years old somewhere on the battlefield. He couldn't bear to take her back for treatment. After learning that the girl had lost her memory, he decided to adopt her.
The second prince of the Cang Ao Empire fell into a coma due to an accident while saving others and was bound by the system to complete the task before he could return to the real world.
The nobles of the Fengyin Empire were dissatisfied with the behavior of the second prince, so they sent an undercover agent to the residence of a count in the Cang Ao Empire to wish him a helping hand.
But is the girl injured on the battlefield really innocent? Can an undercover agent escape unscathed after completing his mission?
