Wen Minliu came to a deserted planet. He gained the worship of the local indigenous people. He must develop the technology of level three civilization within two thousand years to save his lover who fell into the black hole... Throwing bricks at each other with primitive people, confronting nomads with swords, setting up ladders to attack fortified cities with cannons, and sailing on sailing ships to open up great shipping routes. Steam factories produce large ships and cannons, oil and electricity support aircraft and missiles, steel torrents use nuclear bombs to clear the way, and aircraft carrier fleets rush into laser positions. Until facing space Zerg, subspace chaos, and even opponents using dimensional weapons and ultimate laws to fight, Crazy Infrastructure finally became the first civilization in the universe.
