In the Lianghuai Salt Fields during the Tianqi Period, buried under the white grains of salt were the bones of the saltmen. Lu Zhen was originally a saltman who made a living by boiling the sea. He had accepted his fate all his life, but under the whip of Yan Huai, Yan Song's distant nephew, he watched his father being beaten to death. His sister jumped into the "Ghost Sees Sorrow" swamp to protect her innocence.
When he broke the rope from the stake, what he had on his waist was not a salt rake, but a spike sharpened from wolf bone that was stronger than a knife. On the way to escape, he killed robbers and fought against Jin Yiwei. In the black jail of Baoying County Government, he met "Mr. Fang" who had a thorough understanding of the world. The once docile lamb sharpened its fangs in the blood and fire: he learned to disguise weakness with tears, and hid the sharpest murderous intention in the humblest posture. He even easily passed the charge of "murderer" to someone who deserved more death in the court.
But he could not escape the trap of troubled times. The secret war between the Donglin Party and the Eunuch Party spread to the salt field, and the wolf skin he hid in the reeds turned out to be the key evidence to bring down the corrupt party. In front of him was the embroidered spring knife of the Jin Yiwei, and in the back was the dead soldier raised by the salt merchant. Even the head catcher Chen Xiao, who had "cut the fence" towards him, looked at him more and more like he was looking at a useful knife.
Lu Zheng held the polished wolf bone and stood in the gap between the salt field and the officialdom. What he wanted was never fame, but Yan Huai's blood and a world where his sister could rest in peace. But this road has long been deviated - when intrigues and blades are intertwined, and when former enemies offer an olive branch, should he be a knife of revenge, or a chess game that stirs up trouble?
