Zhang Chen, a former real estate salesman, activated the most powerful fishing system out of resentment for salted fish, and counterattacked from a fishing novice to a humanoid sonar in the black pit arena, becoming the top player in the fishing world. He teamed up with his partners to establish Future Fishing Technology, relying on short videos and innovative business models to gain a foothold in the market, and gained a reputation as a philosopher in the fishing industry. Later, he discovered that the system was a product of the AI project "Deep Sea Fish" and he was just an experimental subject. The extreme core of AI division, "The Abyss", wants to use water to devour humans. He assembles the human fishing king alliance to fight against him. He has gone through dangerous situations such as the decisive battle on the Yellow River, time travel, and the Bermuda tide resistance, and even lost his comrades.
