Lin Xuan, an orphan from the slums, was adopted by the Lin family but was bullied because of his "wasted bloodline". The sealed dragon scale bloodline in his body hides a shocking secret. Under the shadow of family humiliation and the mysterious death of his parents, he accidentally activated his bloodline and was taught the "Nine Dragon Secrets" by a mysterious ghost doctor, starting a counterattack.
Su Li, the daughter of the reclusive ancient Wu family, lurks in the city with her icy physique. She crosses paths with Lin Xuan while tracking down a family traitor. She was cold and aloof, but was attracted by Lin Xuan's unyielding tenacity, and even discovered that his dragon scale bloodline was secretly related to her own ice soul.
Lin Xuan rose up step by step in his training, from the underground arena to the secret realm of ancient martial arts. Between the oppression of the Lin family and the internal strife of the Su family, he uncovered the truth about the death of his parents while working side by side with Su Li. In the fierce battles and emotional entanglements, he finally awakened to the secret meaning of "Dragon Roaring Nine Heavens", broke the shackles of class, and became a legend that stirred up the urban martial arts landscape, explaining the true meaning of "the heart of a strong man begins with perseverance and ends with true love."
