During the Zhenguan period, in order to eliminate the remaining forces of the late Sui Dynasty and quell the chaos in the world, six gates were established and an organization "Eagle Dog" was created to train young people to jointly defend the Tang Dynasty.
Cui Ye and Cui Chi, who were originally the Boling Cui family, changed their surnames to Zhai in order to hide their identities. The brother and sister concealed their identities and joined the "Eagle Dog". After numerous cases, they finally completely eliminated the forces of the late Sui Dynasty and gained love and friendship.
Purpose: Feelings of family and country
