In 1937, during the Battle of Shanghai, modern-day military enthusiast Lin Feng transmigrates into the commander of the Jiading Security Corps and activates the “Rise of the Nation System”: kill enemies to get equipment, defeat officers to gain skills, and protect civilians to build prestige. From a local security corps to a German-equipped division, from guerrilla warfare behind enemy lines to the Liberation War, he uses tactics far ahead of their time to carve a path through the meat grinder at Luodian, save civilians amid the ruins of Nanjing, and establish a base deep in the Maoshan Mountains. When the War of Resistance ends, he should have returned home in glory, but instead he resolutely leads his troops north. In the subzero, snowbound cold of Chosin Reservoir in Korea, he uses modern weapons and equipment obtained through the System to fight a life-or-death battle against the U.S. Marines’ First Marine Division, their elite force. From Hanyang rifles to bazookas, from the night raid on Luodian to the bloody battle at Xinxing-ri, this is an epic spanning fourteen years of warfare, from the War of Resistance to the aid of Korea. See how Lin Feng, starting with a small security corps, protects the lifeblood of China and forges an immortal military spirit for the New China on the shores of Chosin Reservoir!
