The modern migrant worker Gao Chong crossed over to become Gao Chong of the Southern Song Dynasty, formed a rebel army to fight against the Jin Dynasty, assisted Yue Fei in the Northern Expedition, and later established the Daxia Dynasty. After he became emperor, he innovated the system, promoted science and technology to promote industry, and sent fleets to expand overseas and connect global trade. In his later years, the Zen crown prince unexpectedly traveled back to modern times when he was sixty-five years old, and wrote the legend of the Southern Song Dynasty into a book, leaving behind an immortal story of saving ancient mountains and rivers with a modern soul.
