The General of Jinling Hall

Tang Zhen is a mediocre military enthusiast from a second-rate 211 university, with no military career to his name. He transmigrates to 1937 and becomes the distant cousin of a high-ranking officer! At the time, Jinling Province is on the brink of disaster. Despite having no System, no Brother Yunlong, and no special-forces skills, the two men lead soldiers and civilians in a desperate resistance, greatly reducing our military and civilian casualties. Later, when his cousin retires, the protagonist takes advantage of the conflicts among the great powers to minimize China's losses and help the nation rise. Romance and spy-war plots are added periodically, and then revised periodically as well!
