For the sake of national survival, I use a dual-system fishing technique to bring the Flying Dragon

My name is Zhang Tiange. An ordinary fisherman, I started out blessed by the Fish God: max level luck! Just as I was about to show off my skills, I entered a national fortune instance! Suddenly, I was in my element! ...In a world where Earth's resources are depleted, a national fortune survival challenge has emerged! Each country sends 100 people to enter an unknown world to challenge. The resources obtained during the survival will be returned to their country ten thousand times! In the Dragon Kingdom, there are special forces soldiers, long-distance runners, actors, and an ordinary fisherman, Zhang Tiange. The whole nation is in an uproar, lamenting the Dragon Kingdom's bad luck. You must know, the other countries are all highly skilled professionals! With Zhang Tiange's "max level luck" blessing, the intelligence three-choice system becomes three intelligence reports per day. [Snowy ground beneath my feet: There are stone houses built by people ten thousand years ago] [Three hours later: Fish appear!] [Fifty miles southeast: There is a hot spring!] While the contestants from other countries are still eating snow to fight hunger, Zhang Tiange is drinking tea and enjoying the aroma of roasted meat in the stone house. The world was shocked by how a fisherman turned his life around!
