Lin Xiaoman, a civil engineering intern, is struck by lightning while clutching a piece of rebar at a construction site and transmigrates!
From then on, a figure of steel and sinew appears in the martial world of the Northern Song. The good-for-nothing disciple cast out by her sect turns out to be a construction fanatic wielding modern black technology! Magnetic inner power draws in a rain of arrows, concrete principles enhance her protective aura, and the Rainstorm Pear Blossom Needles meet the surveying techniques of a total station. The thousand-year-old world of martial arts is utterly outclassed.
From Bianjing's Rainbow Bridge to the Liangshan Marsh stronghold, from the Mohist mechanized city to Western Xia's Iron Hawks, she wields rebar to rebuild order in the martial world. Steel rods shudder and unleash magnetic storms as she breaks formations; when she builds cities, she applies the principles of structural mechanics. Even when she drinks and plays finger-guessing games, everything she does has the solidity of reinforced concrete. The imperial watchdogs call her a witch, and venerable martial artists accuse her of breaking the rules, but they cannot stop the young master of the river guild from volunteering as a human rangefinder or the master mechanic from begging for her concrete formula.
When a rift in space and time appears amid the clash of armies, Lin Xiaoman faces her cruellest choice: return to the modern world with the secret of ancient black iron, or become the foundation stone that builds the Song Dynasty? A legend erased from the history books finally reveals a glimpse of its true glory, a thousand years later, when half a rusted rebar is unearthed at a construction site!
