Xiao Zhenbei, the Great Zhou dynasty's mighty general, stubbornly defends the isolated city of Shazhou. When the city runs out of food and faces utter desperation, he unexpectedly gains the ability to travel between ancient times and the modern world. To save the city's starving and freezing soldiers and civilians, he sets aside his dignity as a commander and earns money in the modern world through physical labor, taking on jobs as a mover, a personal fitness trainer, and a commercial model. He brings food, cotton-padded clothing, greenhouse technology, and military-industrial materials back to ancient times, providing for the people and modernizing the army. With help from his modern friends Peng Shui and Zhu Qingfeng, he fights off invasions by the Louju barbarians while developing and rebuilding Shazhou, embarking on an inspiring legend of civilizational advancement.
