Industrial punk Daqin: the combination of black powder and bronze crossbows, warships driven by steam engines, and the Great Wall made of cement.
Two-hero mode: The protagonist Gu Qing is responsible for "investigating things to gain knowledge" (technique), and Ying Zheng is responsible for "emperor's mind" (strategy). The two are both teachers and friends. Ying Zheng will not live forever, but he hopes to plant the flag of Qin all over the world in his limited life.
