"Ancestor! My clan is in great danger. I hope that ancestor can open

your eyes and save the last hope for my clan!"

In Northern Sky City, young Lin Yan, the second son of the Lin family, faces a harsh reality. Despite his family's warrior lineage, he lacks the ability to cultivate martial arts. However, Lin Yan's life takes an unexpected turn when his older brother, Lin Shuang, a renowned martial prodigy, returns home with malevolent intentions. Lin Shuang, embittered by perceived injustices, attacks his own family, leaving Lin Yan's parents gravely injured.

In a desperate move to save Lin Yan, his mother, Luo Shan, takes him to the family's ancestral altar. There, an ancient ritual involving a mysterious bronze sword is performed, infusing Lin Yan with immense, ancient power. Despite Lin Shuang's attempts to intervene, the ritual completes, but Lin Yan vanishes in the process.

Ten years later, Lin Yan is found living among a group of orphans, having lost all memories of his past. He and his companions survive by thieving, led by their 'Boss Hee,' who possesses minimal martial talent. Tragically, Boss Hee is fatally wounded in a confrontation with the powerful Yao Family, leaving Lin Yan and his friends to fend for themselves. Before leaving, Boss Hee’s final wish was for Lin Yan to seek a better life.

Haunted by his inability to protect Boss Hee and with a newfound determination, Lin Yan, now equipped with the ancient power from the ritual and Boss Hee's final words, sets out to uncover his past, understand his mysterious abilities, and seek justice.
