I Stole Whitebeard's Knife and Went to Fight the Sea Monster!

Sigurd, who had just traveled through the world of pirates and turned into an eight-year-old kid, originally planned to develop in an obscene way. However, the system called the Natural Overlord was caught off guard and awakened. Starting from stealing Whitebeard's Congyun Cutter to chop the Sea King, Sigurd became the most wanted criminal with the highest bounty, the most ferocious, the most influential, and the youngest in the history of the World Government! During the war, the eight-year-old Sigurd beheaded Admiral Akainu and roared to the world! "I will start a new era! Following the footsteps of the Great Secret Treasure, you have fallen behind! Follow me and overthrow the rule of the World Government!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
