In the Qinglan Territory where there are many sword cultivators, Ling Chen, a descendant of the Ling family in Canglan City, was born with a sealed sword bone. He made no progress in his three years of training and became the laughing stock of the family. He was even more humiliated when his fiancée Liu Ruyan, the eldest daughter of the Liu family, broke off the engagement in public.
In despair, he accidentally triggered the black ancient sword pendant around his neck, awakening the remnant soul of the ancient sword god who had been sleeping for thousands of years - Jian Lao.
Under the guidance of Jian Lao, Ling Chen unsealed the sword bones, embarked on the path of sword cultivation, and counterattacked in desperate situations. With his astonishing talent in swordsmanship, he learned the lost ancient sword skills, emerged in Canglan City, and regained his own dignity.
In order to seek stronger power, he left Canglan City and went through academy trials, secret exploration, and cross-region battles. He met a group of like-minded partners, and also encountered pursuits and plots from various forces.
As his strength increased, Ling Chen gradually discovered that his life experience was not that simple. Behind it was the rise and fall of the ancient sword cultivating civilization, the millennium grudges between good and evil, and the shocking secrets of the survival of many worlds.
He will hold the Burning Sky Ancient Sword, fight against the dark forces, uncover all the mysteries, and eventually become the master of the Burning Sky Sword that protects many realms, writing a legendary chapter about passion, growth and redemption.
