In 1935, Chen Xingbang, the fifteen-year-old legitimate eldest son of the Guangxi Clique, awakens with the soul of a history teacher from 2025 and knowledge of the future. He gives up on reforming war-torn China and instead makes Southeast Asia his base. Through ethnic replacement, technological supremacy, and great-power maneuvering, he expands at breakneck speed amid the flames of World War II, eliminates the threat posed by Southeast Asia's indigenous peoples, and builds a Chinese empire on which the sun never sets, spanning the Pacific and Indian Oceans. He rises to become one of the world's three superpowers and forges a century-long dynasty.
