Ocean Overlord: Starting with a Great White Shark Clone

(Livestreaming + Foraging at Sea + Salvaging a Nuclear Submarine + Tens of Billions) Jiang Bai gets dumped by his girlfriend. He quits his job and returns to his fishing village to take some time off, never expecting to awaken a System! "Ding! Ocean Avatar System awakened!" "Obtained an initial S-rank avatar: Great White Shark!" "Ding! Congratulations, Host, you've completed the task and earned the skill: Underwater Breathing!" "Ding! Congratulations, Host, you've completed the task and earned evolution points. Great White Shark has evolved into a prehistoric Great White Shark!" With the help of the System, Jiang Bai takes his boat out to sea. One haul nets him hundreds of pounds of tuna, the next more than a thousand pounds of large yellow croaker, along with precious pearls! "Huh? Why is this so heavy?" He hauls it up and finds he's actually salvaged an Eagle Sauce nuclear submarine!
