When disaster becomes the only way for humans to continue their lives,
When maintaining species balance becomes the only criterion for survival,
All human struggles will have meaning.
The Patriots and the Half-States stopped fighting for centuries and joined forces to fight against Hegus's "invasion" in an unprecedented way.
Su Zilin, a young man who can predict the future, saw a future where human leaders slaughtered human beings; a future where comrades killed each other; a future where nuclear war could not end...
But changing anyone's future may be devastating to the entire human race...
The development of society will eventually lead to human beings killing each other. Would it be a better future to work together to fight against Hegus?
Enter a parallel city defense, a parallel world.
Concept: The balance of species is the law for the continuation of life
