Mountains and Rivers Are for Hire, Old Friends Return

When she was young, Fu Chen met Mo Yongnian (A Yu) in an accident, and the two made a vow. After growing up, the southern country where Mo Yongnian lived proposed marriage to the northern country, but Fu Xu didn't know that Mo Yongnian was the person she was looking for, so she ran away to the southern country, but met Mo Yongnian's motorcade on the road. When Mo Yongnian asked her name, Fu Xu said her name was Ning'an and followed Mo Yongnian back to the southern country. In an accident, the two discovered that Mo Yongning had conspired with Bei Nu and planned to occupy the two major countries. Forced by national security, Fu Chen returned to the Northern Kingdom after her identity was discovered and persuaded her father to fight against the enemy with the Southern Kingdom. After winning, the two lived happily together.
