Poor little Sheng Wei, whose father did not love her mother, went on a trip to the sea on her 21st birthday and was blown away by a sudden tornado. When he woke up again, he was shocked by what he saw. Not only did he grow a tail, he also got a mean system. The system forces him to complete tasks every day to make him the most powerful island owner in the world. Sheng Wei fights against the system every day for laziness. Until one day Sheng Wei picked up a human being at the beach. Except that he didn't like to talk and loved to eat fish, he was good at everything!
