Fifty years after the nuclear war, in the wasteland, those who can fight and kill have become heroes, while Ji Xun is just a "waste" who can read the wall. He can see through the load-bearing weaknesses of the ruins at a glance, and can use three steel beams and abandoned carriages to build a maze to strangle mutant beasts - but no one thinks this is a superpower. When the predators' iron cavalry approached the settlement, and when the survivors only believed in bullets and gunpowder, Ji Xun opened a moldy "Architectural Structural Mechanics" and drew the last escape route on the drawing. He does not build fortresses, only traps; he does not build high walls, only forks of death. This ruin will become his own chessboard.
