National Fate Survival: I Get a Hundredfold Return and an Encyclopedia System

In 2048, three years remained on the Doomsday countdown. A higher life form calling itself the “Observer” arrived on Earth, bringing devastating news: intensifying solar storms would completely destroy Earth’s ecosystem within three years, bringing human civilization to an end. The only chance of survival was the “Civilization Protection Agreement.” Three citizens would be randomly selected from each country to enter an alternate-dimensional survival battlefield. Only the country that ultimately won would be allowed to preserve its civilization under the Observer’s protection. The losers would be reduced to nothing in the next solar storm. Every resource acquired by a contestant would be returned to their country in the real world at a multiplier of ten thousand. Whenever a contestant died, the cause of death would be inflicted on their homeland with a hundred-thousand-fold penalty. If they were mauled to death by a beast, beasts would attack their country; if they drowned, devastating floods would strike. For the first 30 days, a contestant who died could be replaced by a substitute. After 30 days, death was permanent.
