Lin Hai accidentally traveled through time while playing "Age of Empires 2" in an Internet cafe. When he opened his eyes, he was bound to the "Civilization Evolution System". The initial stage was the Dark Age, and the core of the main base was being generated.
The "Puzzle Land" he is in is a chaotic world where fragments of rules from different eras have been forcibly stitched together. Only the system uses the absolute rationality of resource collection, technological advancement, and military production to establish a cold war order.
The units trained by the system were just cold population figures in the interface. They were neither sad nor happy, but absolutely obedient, which made Lin Hai feel separated. The scout discovered a living human village, and the system marked it as a resource point that could be conquered - conquest can bring about explosive development, but it will crush another way of survival. The system only counts gains and losses, and the choice is all his own.
At this moment, the upgrade options of the feudal era are revealed, and at the end of the technology tree is a greater era of power. He will eventually face the ultimate question: With the absolute power to define civilization, will it create brilliance or another kind of barbarism?
