The Earth clicked on the wrong technology tree and developed other directions of the technology tree to the extreme, but ignored a very simple technology, so that interstellar voyages have never been possible. Aliens have mastered space jumping technology, and countless obviously hostile spacecraft appear above the earth. But what is unexpected is that their military strength when they came to invade the earth was only at the level of the human flintlock era. In front of humans with missiles and other attack methods, they were so weak that it was laughable. So after the war, eight billion earthlings mastered the aliens' space jumping technology, and like a "mad dog out of the cage", they began to carry out reverse invasion in the universe. Is it the domination of the universe or the dark forest that awaits mankind?
