The evolutionary history of the planet's civilization

Very quickly, time flew by.

In a short ten years, after Science and Technology entered the Industrial Revolution.

The world map of each continent was completely clear, and the countries of each continent started a great civilization explosion.

It was not difficult to create practical weapons based on the various scientific and technological parameters obtained, the laws of the universe, and the laws of physics and chemistry. Soon, with the emergence of planes, trains, chariots, and artillery, the distance between continents began to shrink, and the planets as large as the entire earth began to exchange what they needed.

The distance between the two worlds was shortened, and small conflicts began to occur.

In order to stop the war, all the continents had the same goal: To improve the living environment, they used a large number of green plants to improve the concentration of the atmosphere.

This planet's atmosphere was extremely thin.
