When the dragon scales are scattered, the world is in chaos; when the dragon scales gather, the true dragon emerges.
In order to save his brother Liu Yang, Lu Nan, a first-year high school student, was drawn into the vortex of time and space by a bronze pendant. When he opened his eyes again, it was the end of the Warring States Period. There is a reincarnated dragon eye hidden in his left eye, which can sense the location of dragon scales in the world. The ancestor of Kunlun ordered his disciples to go down the mountain to meet people from other worlds and help the dragon return to its throne.
From then on, the young man went down the mountain with his sword: looking for dragon scales, slaying evil spirits, protecting the King of Qin, and ruling the world. The senior brother died in the battle, the master burned away the Nascent Soul, and the young king he assisted was becoming stronger and lonely day by day.
It wasn't until the end that he understood - the so-called destiny means using the lives of a group of people to pave the nine steps.
