Datong, the High Wall, the Escapee from the Eternal Day

Under the steel-gray eternal daylight, ordinary human emotions are suppressed by drugs, and thoughts are unified by the system. Chen Ming was originally an "ordinary" data maintainer, until a hum that shouldn't exist disrupted his cognition - it was a sporadic remnant of the previous world. After being marked as "abnormal" by the system, he chose to escape. Passing through the dense surveillance and cold pipes, he entered a hidden real world, which is hungry, cold, bloody, and painful, but also full of starlight, soil, breath, and tears. Here he learned to work with his hands, hunt with a knife, and gradually understood that living does not mean existing. He is guided by a "messenger" - a chip that records the core vulnerabilities of "Datong", and a "key" that may shake the entire system. As scavengers approach, predators hunt, and "Lin Whisperer" and "Stone Scar" get involved in disputes, Chen Ming is forced to grow from an evader to a successor of the fire. He must choose between a struggle that is almost doomed to failure and a life of survival, and find his own way between order and chaos, false stability and real cruelty. This is not a war to tear down high walls, but a story about "ordinary people" learning how to live like human beings after seeing the lies.
