In his past life, Wu Sui was addicted to gambling, squandered his family fortune, caused his daughter to fall seriously ill without money for treatment, and his wife passed away tragically. He was then tricked and lured by fellow villagers into a telecom fraud park, ending up in a miserable state. Reborn into the year 2000 on the very day before tragedy struck, he finds his family dividing up properties, facing extreme poverty, with his wife and daughter in desperate straits. Awakening the Ocean Illustrated Guide System, Wu Sui gains a radar that can detect seafood on the seabed, completely transforming the good-for-nothing once spurned by everyone. Relying on beach combing to dig up mud crabs, peanut worms, sea cucumbers, and abalones, he seizes the trends of the times and makes his first pot of gold among the mudflats and nearshore seas.
