Many strange occurrences have unfolded along the ancient Yellow River course. Seventy-four years ago, when Chiang Kai-shek blew open the Garden Mouth Dam in Zhengzhou, three dragon serpents surfaced as the levee collapsed. Over sixty years ago, a mysterious exploration team attempting to uncover the Yellow River's hidden secrets encountered a dense fog that devoured crab-eaters at the river's First Bend, along with a group of humanoid skeletons walking within the fog. Simultaneously, two Yellow River artisans opened a colossal ancient cauldron suspended by hundreds of iron chains deep within an abyss for centuries. To their horror, they discovered a living human sealed inside with blood and animal hides. Even more bizarrely, this person was Jin Zihan! To uncover the truth, Monkey and I journeyed deep into the Death Swamp. After enduring countless eerie incidents, we obtained a mysterious diary from thirty years ago, revealing truths hidden for over three decades during the Long March. The greatest secret of the Yellow River's ancient course was thus unveiled.
