When the dragon scales scatter, the world falls into chaos; when they gather, the true dragon appears.
Lu Nan, a high school sophomore, is swept into a time-space vortex by a bronze pendant while saving his friend Liu Yang. When he opens his eyes again, he is at the end of the Warring States period. A reincarnated dragon eye lies hidden in his left eye, allowing him to sense the location of dragon scales across the land. The Kunlun Ancestor orders his disciples down the mountain to meet the stranger from another world and help the divine dragon reclaim its rightful place.
From then on, the youth descends the mountain with his sword: searching for dragon scales, slaying demons, protecting the King of Qin, and bringing the realm under one rule. His senior brother dies in battle, his master burns through his nascent soul, and the young king he serves grows stronger and lonelier with every passing day.
Only at the very end does he understand: what people call fate is a staircase of nine steps paved with the lives of many.
