Chen Jiuhe, the 37th generation descendant of the Yellow River corpse fishermen, appears to be an ordinary boatman, but in fact he possesses the secret technique of "tying dragon ropes" passed down from his ancestors and the ability to "discern evil spirits by listening to water". My grandfather's "bronze coffin corpse" disappeared three years ago, leaving behind half a bronze piece engraved with a dragon pattern. The nine and eighteen bends of the Yellow River hide the "secret story of the sinking dragon", and those who fish for corpses are responsible for "fishing out grievances and suppressing evil spirits in the river". Nowadays, a mysterious organization with evil intentions covets the power of ancient civilization under the Yellow River, and uses any means to achieve its goals, repeatedly obstructing Chen Jiuhe. Chen Jiuhe relied on his own abilities and understanding of the Yellow River to gradually get closer to the truth in solving the strange events. However, he not only has to face the harsh environment of the Yellow River and the threats of various supernatural phenomena, but also faces the misunderstanding and obstruction of local villagers. On the way to pursue the truth, he and the person who helped him had a misunderstanding because of other people's misleading. As the mysterious organization accelerates its actions, a disaster in the Yellow River is imminent, and Chen Jiuhe must race against time. Even if he ultimately succeeds in preventing the disaster, he will pay a heavy price.
