In the final years of the Southern Song, the land was shattered, and the Mongol hooves trampled Jiangnan.
Song Jing, an orphan from a poor family, carried the burden of a blood feud and his dying younger sister. He crawled out from among the corpses of refugees in a hellish wasteland, and was taken in by Mo Yun, the former dynasty's chief artisan. In Song Jing, Mo Yun saw an undying spark: hands capable of unraveling the principles behind all things, and a heart that would not yield, even in the direst circumstances.
By improving weapons, rallying people, and quietly securing resources... tempered in blood and fire, he was no longer a fleeing insect, but a "Ghost Craftsman" wielding the power of science and engineering, with the ambition to embrace the realm!
Can technology become the foundation for saving the world? Can a poor-born man hold up the sky in the apocalypse? As the dynasty's setting sun sinks beneath Yashan, will Song Jing's journey forge a new realm for the spirit of craftsmanship and the common people?
