Dimensionality Reduction Strike: Rebuilding Civilization from the Copy

In 2046, a thick gray and black fog engulfed the world. Lin Mu, a history researcher, was trapped in the library and witnessed the tragic death of his colleagues, but he accidentally activated the "Civilization Fire" protocol - unlocking the 5,000-year-old human technological tree out of thin air in his mind: from gunpowder formulas to hybrid rice, from steam engines to chip lithography, all knowledge was at his disposal. The world in the fog is far crueler than he imagined. Countless broken "small universes" form deadly copies. Western gods, Eastern ancient cultivators, and evil monsters take turns appearing, and human beings are reduced to harvested lambs. But Lin Mu soon discovered a secret - these copies were all tampered and forgotten projections of human history. While others were desperately fighting for their lives in the dungeon, Lin Mu had already started making steel, generating electricity, and building bunkers. When the gods sent down the punishment, he took out high explosives with his backhand. When the ancient cultivator laughed at him for being a mere mortal, he brought a reinforced company of modern firepower to level the mountain gate. This is not a one-person counterattack. This is a civilized revenge. From today on, let the gods re-recognize the word "human".
