Jack accidentally transmigrates to another world and saves a drowning Fox-eared Girl. After exchanging the phone he always carried with him for an island pearl, Jack begins his life as President of New World Island in a foreign world. This is a peculiar world of islands with cold weapons. Except for the original continent, there are countless islands floating in the endless sea which point towards a mysterious treasure. The islands can be traded and also be annexed to expand the scale of an island. Also, there are countless treasures waiting to be found. Fox-eared Girl: “President Jack's island is the happiest place in the endless sea.” Island Dragon Guardian: “The magic of our President is simply devastating!” Rainbow Island Princess: “Even the lives of commoners on President Jack's island are countless times better than that of mine as a princess.” King of the Sea: “If you don’t want your race to perish, never provoke Jack's island!”
