Canglan Star, 94% of the surface is covered by the deep blue sea, with scattered islands scattered like broken jade. It is a desperate situation for terrestrial life, but it is a paradise for sea beasts nourished by spiritual energy. The evolved deep-sea behemoths wear heat-resistant scales, have toothed fins that can crack steel, and are faster than the speed of sound. Behemoths weighing one million kilograms can be seen everywhere, and legendary sea beasts can swallow islands for food. The law of the ocean is the law of the jungle, and it has also become an opportunity for humankind to survive - land resources are exhausted, and only by hunting sea beasts to obtain spiritual energy and resources can civilization continue. And fishing is the best way to break through the defenses of sea beasts. The angler lures the beast with bait, uses the hook to avoid the scales and thorns, and uses his martial arts and skills to pull the giant beast ashore, becoming the most noble savior of civilization. Young Li Richen was born in Linhai Fishing Port. Carrying an ancestral fishing rod with a mysterious system, he stepped into this magnificent era of deep-sea hunting with an ordinary body. In the fishing of blood and fire, he uncovered the ultimate secret of the spiritual ocean and the evolution of sea beasts.
