Where energy shields coexist with steel blades, and genetic engineering goes hand in hand with huddling around campfires, welcome to the “Erosion Abyss Era.” Here, civilization is rebuilt in a world out of joint, and the truth lies buried beneath the Fault. Lin Qi, a low-ranking technician responsible for maintaining “ancient technology,” is exiled to the wasteland after cracking a piece of code. He soon discovers that the high technology worshipped as ancient is nothing of the sort, and that the so-called apocalypse is actually a century-long experiment to select which civilization will survive. Is knowledge a privilege or a right? Should civilization be guided toward a new future, or evolve on its own? With the truth that could overturn the world in his hands, he must make a choice. This time, the future will be written by the land itself.
