Billions of Nations Awaken, I Build the Strongest Civilization

Traveling across the world, everyone gets a main city and population, and hundreds of millions of countries rise from then on. The talents are awakened at the beginning. Everyone else is the God of War, the Holy Mage, and the Holy Priest. You can awaken an 'infrastructure increase' for us. It doesn't matter, first bind the strongest civilization system. Are you still in the Iron Age? Sorry, please drive the tank out for me first. No matter how low your talent is, you will be knocked down in one shot. The world of all races merges, and the human race is reduced to food rations? Sorry, let me know about nuclear weapons. Gods and demons appear, and all races wither? Sorry, the God-killing Star Cannon is in place. City war, national war, war of all races. Song Nan pacified hundreds of millions of countries, massacred thousands of tribes, killed gods and demons, and created the strongest civilization in the starry sky.
