Qin Hu of the Flame Imperial Guards and his companions uphold the belief that "the Son of Heaven guards the state, the Imperial Guards guard the land, the bones of a hero hide in the martial world, and no name left behind even in death," representing a heroic act of courage to defend the realm and the rebellious forces. They possess both the responsibility of the imperial guards to safeguard the peace of the land and the chivalrous hearts of the martial world.

Qin Hu, who has always been unrestrained and unruly, gradually becomes entangled in a shocking conspiracy concerning the people of the world as he investigates a bizarre murder case in a village, while also uncovering the mystery of his origins buried for over twenty years. In the most dangerous investigations after cases, threats from enemies, betrayal from colleagues, and suspicion from comrades have not diminished Qin Hu's sense of justice.

In the end, his personal charisma inspired his companions. Everyone overcame all obstacles and feared no authority, all to seek justice for lost innocent lives, restore peace to the world, preserve the nation for eternity, and live up to the name of the Flame Imperial Guards, trusted by the people. Working together, they thwarted the mastermind's plot to disrupt the realm.
