A talented but unknown senior fisherman, during an ordinary night fishing at the Pearl River Estuary, encountered the legendary giant, a century-old dragon that easily broke his inherited fishing rod. This "humiliation of breaking the pole" was recorded and ridiculed by others, but it ignited an obsession deep in his heart: to conquer that fish.
The master's vague last words before his death, half a tortoise shell engraved with mysterious golden patterns, and the sudden appearance of anonymous guidance led him to a deep-sea mystery that was far beyond imagination: the dragon's trap was not the end, but just the "threshold." The real target is the prehistoric ancestor known as the "Mingyuan Dragon Dragon" hidden under the Devil's Trough in the South China Sea. It weighs more than ten thousand kilograms and has survived for more than four thousand years. It is close to gods or demons.
The path of pursuit is fraught with difficulties. The Lin faction not only has to face the incomprehension and departure of his girlfriend, the pursuit, interception and armed robbery by the modern scientific expedition team, but also has to delve into the ancient legend of the Danjia fishing village, search for crazy survivors, and obtain forbidden fishing gear made of "soul-absorbing wood", "mermaid silk" and "heart blood". Every step reveals the deeper secrets of the giant: its history of being entangled with humans for thousands of years, its nearly intelligent consciousness, and the power related to control and sealing hidden in the golden markings all over its body like a charm.
In the end, Lin sent his boat alone, broke into the devil's trough in the storm, and launched an earth-shattering fight with the giant. This fight brought him into a different space beyond reality - "Mingyuan". Here, he faces not only a confrontation of strength, but also a test of will and ancient wisdom. He must make a choice: become the king of fishing who conquers giant beasts
