The Last Emperor of the Southern Song Dynasty, Zhao Bing, Destroyed the Yuan Dynasty

At the end of the Southern Song Dynasty, the last emperor Zhao Bing was accidentally abandoned in the wilderness as an infant and adopted by hunters from Qiongzhou Prefecture. He learned hunting, survival and boxing skills in the mountains and forests without knowing anything about his life experience.​ After he became enlightened and literate, he discovered a spaceship from the future while in a cave one day. The intelligence on the spacecraft imparted high-tech knowledge such as physics and military industry to him, and transformed his body to gain extraordinary abilities.​ Zhao Bing used science and technology to guide the villagers to build muskets and fortifications to repel the Yuan army, and then formed small teams to attack and harass the Yuan army, and rescued the captured Wen Tianxiang.​ It also promotes weapons transformation, research and development of specialty commodities, trade Yuanting, Nanyang, Western Regions and other countries to obtain a large amount of resources. During the Yashan naval battle, Zhao Bing arranged for a modified warship to make a surprise attack, defeated the Yuan army, and rescued the Southern Song Dynasty monarchs and ministers. He was identified by his jade pendant and birthmark, and then ascended the throne on the Leizhou Peninsula.​ Formulating a strategy of first surrounding the surrounding areas and then the central plains, he led troops to conquer Japan and Goryeo as rear resource bases, owned many minerals and grain fields in Southeast Asia, and regained the occupied islands and Sichuan and Shu lands from the Yuan army. Different strategies were used to weaken the Yuan court and support anti-Yuan forces in various places, laying the foundation for the Northern Expedition to the Central Plains.
