In the 137th year of the New Era, invisible and strange laws envelope the world without warning.
No one knows where it comes from. They only know that every seven days, a "Chosen One" will be randomly selected from all over the world and forced into a copy of the bizarre rules. Common sense in the copy is invalid, and life and death are determined by the rules: the rules written in black and white are true and false, and the weird things in the dark follow the rules. One wrong step will destroy both body and soul, leaving not even a trace of existence.
And the result of each level will be directly bound to the national destiny of the corresponding country——
Rewards for customs clearance will arrive randomly: extended lifespan for all people, breakthroughs in core science and technology, expansion of territorial resources, skyrocketing food production, and even eliminating natural disasters and curing chronic diseases of the people;
The punishment for failure takes effect immediately: loss of lifespan of the entire population, technological regression, land desertification, reduced food production, breeding of plague, and national power declining at a speed visible to the naked eye.
In just three years, dozens of small countries have been completely wiped out in the long history due to consecutive defeats, and powerful countries have been frightened step by step due to the ups and downs of their national fortunes. The strange rumors about rules have become the Sword of Damocles hanging over the heads of all mankind.
