Zhao, a young man from Beidiao, could not bear to be involved in the scandal and resigned. While rescuing people, he accidentally activated the sea fish contract system, which allows him to contract with marine life and share the view of the seabed. After he returned home, he rented a large fishing boat to go to sea in order to avenge the shipowner Wang Guoqing who injured his father. Relying on the system to command various types of sea fish to catch groupers and dragonheads, his income exceeded one million in a single trip to sea, and he paid off his family's huge foreign debt. He met Chen Feng, a seafood vendor, and fell in love with his sister Chen Xiaoxiao; he rescued Dabai, a dolphin trapped by poachers late at night, and the dolphins took the initiative to help him round up the fishing shoal. Parents and brothers returned home to reunite after working, making money steadily while guarding against the Wang family's revenge.
