It was during the Sui Dynasty. After the Northern Dynasty’s Sui Wendi destroyed the Southern Dynasty’s Chen State, it ended the long period of division between the Northern and Southern Dynasties. The survivors of the Chen Kingdom were unwilling to see the country perish. In 601 AD, they gathered a large army and rebelled, intending to restore the country.
Sui Wendi immediately ordered the suppression of the rebellion, but what surprised the Chen Resistance was: The Sui Dynasty’s anti-riot force was made up of less than twenty people, and the leader was actually a ten-year-old youth!
This mysterious cloaked youth used a mysterious "Golden Sword" to instantly wipe out tens of thousands of Chen Country’s rebel troops. The mysterious young man had established his reputation with the invincible Golden Sword (Xuanyuan Sword). From then on, everyone’s expressions changed upon hearing it. No one dared to rebel against the imperial court anymore.
Sixteen years later, during the reign of Emperor Yang Guang of the Sui Dynasty, the male protagonist Chen Jingchou was ordered by his master to embark on a journey to find the legendary five ancient artifacts. Chen Jingchou was a descendant of the Chen Nation.
