War Trading System

Mountains and rivers stretch ninety thousand miles across, and there are mountains of corpses and no one to bury them. When I regain the old mountains and rivers, all the enemies will bury you in their graves. When the earth was as curious as a baby about the entire universe, a suffocating alien fleet came to this solar system. What they brought was not friendship, but naked aggression. The earth is crying and bleeding, but it cannot stop the destruction of earth civilization. From then on, the entire earth has entered an era of extinction. And in this sad era, a magical system appeared. From then on, a young man shouldered the hope of the entire civilization. Under the baptism of war and fire, the civilization continued and reached its peak.
