I Burn Through My Lifespan to Propel Great Tang Into the Industrial Revolution

Thanks for the invite. I'm in the Tang Dynasty, Empress Zhangsun is my sister, and Zhangsun Wuji is my brother. A smile tugged at the corner of Zhangsun Wuyi's mouth. “From the start, doesn't this mean that as long as I don't get myself killed, I can live out my days doing nothing?” The original owner was a playboy who spent his days chasing cats and dogs. His beloved family hadn't even arranged an official post for him. He was bitterly frustrated. In the ninth year of Wude, Crown Prince Li Jiancheng was defeated, and Wei Zheng and the others defied death to make their point. The original owner decided to take a huge gamble and save Wei Zheng, but ended up imprisoned on charges of treason. He never expected things to go so wrong! After more than ten days in prison, nobody had even bothered to check on him. Zhangsun Wuyi: No way, no way. Was I really picked up by my father? 【Ding! Would you like to exchange your lifespan for...】 Good grief, there's something wrong with my System. It costs lifespan?! Make salt, brew wine, produce paper, raise pigs, sell soap… Then smelt iron. After all, steel is the foundation of every product of the Industrial Revolution. Build factories, set up assembly lines, make machinery and looms, open printing presses, and print books and newspapers. By spending his lifespan, he drags the Tang Dynasty kicking and screaming into the industrial age! In the tenth year of Zhenguan, a coalition of Turks and Tibetans, two hundred thousand strong, attacks the Tang Dynasty. They reach the Wei River, and Chang'an is in grave danger! Just as Li Shimin despairs, Zhangsun Wuyi leads a steel torrent out of the Jingdong Industrial Park and roars, “The truth is always within the range of the cannons. Anyone who invades Tang lands will be damned!” Boom!
