Overnight, all the members of Yuyang County's Changfeng Escort Bureau were wronged. Young Zhang Linchuan carried the longevity lock left by his father and fled to the end of the world under the escort of the old escort leader Meng Tieshan.
In the whirlpool of "Ghost Seeing Sorrow" in the Yellow River, is it a sunken ship, or is it the truth about the "Qingping Case" twenty years ago? The carvings on the inner side of the longevity lock point to the light of Caobang's sword, the ironclad evidence of the six doors, or the sound of candle shadows and axes behind the high walls of the deep palace?
He meets Pei Xuezhou, whose identity is a mystery. She hides a silver needle in her sleeves, which also hides a temptation for him; he gets involved in a bloody battle between the Cao Gang and the Cao Gang. The collision between the green flag and the black flag unexpectedly leads to the collusion between the demon sect and the court.
When Meng Tieshan trusted each other with a letter in blood, and when the dragon pattern was pieced together at the bottom of the river, Zhang Linchuan finally understood: what his father left behind was not a revenge knife, but a blade that split the fog of rivers, lakes and temples.
But the road ahead is long, the water of the Yellow River is still flowing, and grievances are like a tide. Where should his sword fall?
