Final Battle

72 Years ago, two mysterious extraterrestrial visitors arrived on the planet Pado, giving humans a superpower called the 'Graviris Ability'. The territory of human society was rapidly changed. With the help of aliens, the nomads on the continent of Briphi established the Nice Nantu Empire, which rose rapidly and began to expand globally. The end of conventional war will be an all-destroying nuclear war. At that time, the "light quality conversion technology" as the entry ticket to the divine civilization had just sprouted in the laboratory of the Ford Federation. This is a disaster for civilization, and it is also the last battle for humans on Planet Pado before heading to the star sea. Can human civilization survive the war and go to the star sea?
