In 1892, the Qing Dynasty stands on the brink of collapse, crushed between the greed of Western colonial powers and the rising ambitions of Japan. Lin Daxin, a young man born into a naval family, discovers an ancient ring that grants him an impossible ability: to travel through time. He can journey to the 21st century and return to the past carrying anything he has touched. What the modern world sees as Cold War scrap—T-62 tanks, BTR-60 armored vehicles, and J-class submarines awaiting dismantlement—are, to Lin Daxin, divine weapons capable of rewriting history. Amid political intrigue involving Li Hongzhang, the Beiyang Fleet, and the looming threat of Tsarist Russia, Daxin secretly builds a force in the Northeast known as the Dingbei Army. What happens when modern radar detects colonial wooden warships? Or when diesel-powered submarines sink Europe’s proud steel fleets? Lin Daxin does not merely seek survival—he is determined to ensure that, in this timeline, Asia’s glory will never fade.
