Forty-three years ago, he took up the badge and walked into the fog.
Chen Xiangdong buried his youth in the dense forests of the mountains along the Yunnan-Myanmar border. The drug lord "Laughing Buddha's" casinos, a blood-soaked initiation, the treacherous "Ghost's Lament" pass littered with bones... Codenamed "Snow Peak," he licked blood from the blade's edge and walked alone through the abyss, every step falling upon the blood of both himself and his enemies. He thought that once the battles of his life were over, they would be finished for good.
Forty-three years later, she took up the badge and walked into the storm.
His daughter Lin Xiao stood in the retirement ceremony hall, accepting not only her father's badge, but also a flame that had never gone out. She didn't know that every scar on her father's body concealed a tombstone forged from flesh and blood. Nor did she know that although Buddha had fallen, the tangled network of "protective umbrellas" behind him was only just beginning to reveal its monstrous face.
As new types of drugs surge through the undercurrents and a sinister hand reaches into the depths of power, an ultimate covert war spanning two generations and sweeping through both the underworld and the legitimate world suddenly erupts.
Chen Xiangdong must use his battered body to pry open the last iron gate leading to the heart of evil. Lin Xiao, meanwhile, must discern truth from lies in the fog and hold fast to her principles amid betrayal and loyalty. From the border to the courtroom, from a hail of bullets to a battle fought over account books without a shot fired, their enemies are not just drug traffickers, but also the "shadows" lurking beneath the light.
This is a road paved with flesh and blood, and a war that will never end.
Beneath the boundary marker lie bones and drug money; above it stand the police badge and the oath. When the father can finally stand in the sunlight, his daughter has already headed into the deepest darkness. What they protect has never been just a stretch of border, but the blood-red boundary stone between people's hearts, the line that must never be allowed to fall.
