The parallel world "Blue Star" is depleted of resources and faces the crisis of "Great Annihilation". The "National Games Arena" has arrived, and a "destined person" from each country is randomly selected to enter the "Endless Sea" for a survival competition. The protagonist Su Mu, a former special forces soldier and folklorist, has awakened his talent [Fishing Worlds] and his profession [Dragon Marked Messenger]. He can use "National Luck Points" or "Civilization Fragments" as bait at a specific location to catch random items or character projections from all over the world (martial arts, fairy tales, science fiction, genre, etc.). At the same time, he is the only apostle of the Dragon Kingdom's totem "Dragon of Luck". He can borrow the power of the dragon, and his growth also feeds the dragon.
