Gu Yan, a modern architectural designer, traveled through the Southern Song Dynasty and became Gu Shisan, a low-level craftsman. Faced with the eight-magnitude earthquake that was about to destroy Lin'an a year later, and the government's disregard for human life, he used architectural knowledge that was a century ahead of his time as a weapon to launch a massive "urban self-rescue movement." From an earthquake-resistant house to half a city that does not collapse, Gu Shisan wants to make this precarious Lin'an, when the buildings are crumbling, truly achieve - Lin'an does not move!
