(Non-cool writing + no system + national luck + Pokémon structure is rigorous)
Blue Star, parallel time and space.
On this day, a loud and mysterious voice suddenly sounded from the sky and the earth: "The countries of Blue Star will open the national destiny Pokémon battlefield. Each country will randomly select a representative to enter a different world, and use Pokémon to battle to determine the national destiny. All the actions of the representative in the other world will be synchronized in real time to the home country's live broadcast room, and the resources they obtain will also come to the country in proportion. If the representative is defeated and dies, the country will suffer corresponding disasters."
The sound rang in everyone's ears like a bell, causing an uproar. Governments of various countries held emergency meetings, while people were panicked and discussed the sudden change in the streets.
