Survival of National Destiny: I Have an Encyclopedia System for Returns Ten Thousand Times

In 2048, there are three years to the end of the world. A high-level life form calling itself the "Observer" descended on the Earth, bringing devastating news: The continuously increasing solar storm will completely destroy the Earth's ecology within three years, and human civilization is about to end. The only hope is the "Civilization Protection Agreement." Three citizens from each country are randomly selected to enter the survival battlefield of another dimension. Only the country that ultimately wins can continue civilization under the protection of observers. The loser will be wiped out in the next solar storm. Every resource obtained by the players will be returned to the real country at a ratio of 10,000 times For every person who dies, the cause of death will be punished 100,000 times to the motherland - being bitten to death by wild beasts, a beast attack breaks out in the country; drowning, and the country is flooded If you die in the first 30 days, you can be replaced by a substitute. After 30 days - if you die, you will die forever.
