Doomsday War

The vast universe has gone through more than 5.5 Billion years since the creation of the world by the great god Pangu. During this period, it has experienced several world-destroying wars, such as the ancient times, the apotheosis of gods in the middle period, and the nuclear war in modern history. Many races have been wiped out by the war. Now there are only two major races left, the human race, the mecha race, and the Maistri race. However, this is just a legend. No one has actually seen them, and they do not know which race they are descendants of. It can be said that the entire universe is now full of vicissitudes of life, and it is difficult to find a piece of pure land after years of war. The planet has basically been developed, but the destruction continues. The universe is tired, and the dark clouds of war are slowly beginning to envelope every planet. The life of the universe is about to end. Who can stop this, who can change everything, is there a universe outside the universe...
