Transmigrating to the Qin Dynasty: A Tech Emperor's History of Global Conquest

[Not a fast-paced wish-fulfillment novel. Please don't read if that's not your thing!] A bolt of heavenly lightning sends my soul across a thousand years and drops me into the chaotic Qin Dynasty. I wanted a life of wealth and privilege, but the times made me who I am. What sparks will fly when an ancient empire collides with modern technology? I'm the one who controls those sparks. Steam locomotives roar along ancient roads, and dazzling electric light tears across the night sky. I made it all happen. The Six States are locked in conflict and Huaxia is in turmoil, but with my help, the Qin cavalry sweeps across the land like a gale scattering fallen leaves and unifies the world. Yet this is only the beginning. My gaze has already turned to a distant shore. Is this all part of a long-planned conspiracy, or a capricious joke played by the god of fate? What role do I play beneath the wheels of history? Am I a savior or a destroyer?
