Half the Population

Before, Oraman and his men thought Earth would explode, and they were having conflicts with other countries, which was why they went to Mars.

They had made plans on how to survive on Mars before arriving. They had a 30% survival rate.

The most important thing was to find water on Mars. It took them half a month to reach Mars, and they spent another six weeks searching.

They found nothing.

Neige had some very advanced technology. Fifteen days to travel to Mars was enough proof of their advanced technology.

More importantly, they succeeded!

Humanity had set foot on the moon, but landing on other planets had been an impossible task.

Being the wealthiest country in the world, Neige concealed its true capability. The energy cannon was one of the trump cards. The theory was discovered over twenty years ago.
