When the steam iron wheel broke through the morning mist of the Bianhe River, the fate of the Song Dynasty turned to the unknown with the gears - the female machine-craftsman Su Wan emerged with an improved loom, but was caught in a strike frenzy and was stigmatized as a "witch"; the Song and Liao steam warships dueled in the Bohai Sea, and Xiao Tie died as a martyr to reveal the shocking secret that technology originated from the Western Regions.
The powerful minister Zhang Dun used steam weapons for personal gain, Shen Kuo awakened from "technological supremacy" to the guardian of "benevolent skills", Su Wan led an alliance of female craftsmen to break into the court, fight undercover, and finally melted gunpowder cannons into plows and established a covenant of ingenuity among all nations. This technological revolution that spanned five years finally broke through with "gears carrying benevolence", explaining what it means to "use technology to save the world, rather than destroy it."
