What Does It Mean to Rebuild the Human Federation in My Three-Body World?

[Three Body Fans｜Star Civilization｜Civilization Reconstruction｜Two-line Development｜Civilization Game] The Empire of Stars fell, and Generalissimo Yuan Shuai sent the last spark of civilization into the Horizon Needle. When he opened his eyes again, he had come to the earth of the Trisolaran universe and became an ordinary employee with a monthly salary of 4,500 yuan, a rent of 1,880 yuan, and a debt of 2,000 yuan. The marshal who used to rule the stars now has to face first the office weekly report and next month's rent. An undisclosed war, The Trisolaran fleet is heading towards the solar system. Sophons block basic science, ETO lurks among the crowd, scientists die one after another, and humans don't even know that the war has begun. The unobservable relationship between Yuan Shuai and the imperial artificial intelligence "Xiao Hui" made a young man with an ordinary identity and clean experience enter the high-risk list of the Trisolaran civilization for the first time. Starting from a list of dead scientists, he will gradually enter the center of human war. Two thousand six hundred light years away, the Fire Fleet crashed into Deneb. The hull of the ship was damaged, the population was mothballed, and the industry was completely destroyed. Xiao Hui and chief engineer Lin Zhen could only rebuild civilization from the first ruler, the first part, and the first factory. But on the new home planet they chose, there is already a local civilization with nuclear weapons. The Empire has the power to wipe them out, but doesn't have the resources to take over an entire planet. The Trisolarans regard the earth as their homeland waiting to be cleared; the Human Federation also becomes aliens falling from the sky in another world. War, deterrence, trade, technology and integration will push the two worlds towards a completely different first contact, and will also allow a collapsed empire to redefine what the human federation is.
