Xiao Zhenbei, the mighty General of Wuwei, unexpectedly arrives in the modern world. Seeing cars, mobile phones, and food delivery for the first time, he finds everything fascinating and gets into plenty of amusing misunderstandings. When he learns that he can earn money through work in the modern world and exchange it for the food and daily necessities urgently needed in Shazhou, he heads to the labor market and starts with jobs such as carrying goods and hauling building materials upstairs. By day, he earns money and learns about the modern world; then he returns to Shazhou with the supplies. Thus, an ancient general travels back and forth between two worlds, protecting the city behind him in his own way.
