In a modern city experiencing a spiritual qi revival, the martial arts of the Yin and Shang dynasties have returned to the world.
Chen Xuan was an archaeology student until an accident awakened the "Dragon Spine Jade" that had lain dormant within him for a thousand years, making him the inheritor of ancient Yin and Shang martial arts. He can decipher martial arts secrets hidden in oracle bone script and understand the mysteries of the formations on bronze vessels, but this also draws him into a thousand-year shadow war between the "Heavenly Punishment Organization" and the "Chang'an Group."
Luo Jiuli, the legitimate daughter of the Luo family in Shencheng, bears the secret art of the "Nine Transformations of the Black Bird." On the surface, she is a chief appraiser at an auction house; in truth, she is a hidden martial artist who guards the sparks of ancient civilization. Holding half of a fragmentary turtle shell, she appears when Chen Xuan is on the brink of death. Her words, "The dragon's roar in your spine is disturbing me," reveal a destiny entwined in their bloodlines for three thousand years.
When the bronze sacred tree awakens beneath a financial skyscraper and oracle bone script turns into talismans of slaughter, the collision of modern technology and secret Yin and Shang martial arts sets the city ablaze. Guided by the Dragon Spine Jade, Chen Xuan joins Luo Jiuli, who relies on her Black Bird Eye, to rebuild a lost martial civilization amid the forest of steel, from a museum's artifact restoration room to a multinational corporation's quantum laboratory.
