In 1628, the time traveler Zheng Zhilong came to the troubled times of the late Ming Dynasty. Relying on his foresight, he quickly integrated the maritime armed "Eighteen Zhi" and established his hegemony in the southeastern sea area through the victory of Liaoluo Bay. Subsequently, while accepting the imperial court's recruitment to build up strength, he issued the "Taiwan Reclamation Order" to systematically develop Taiwan, and went south to colonize Southeast Asia, gaining huge amounts of wealth and food. When the Jiashen Incident and the Qing army's entry into the customs brought great changes to the world, Zheng Zhilong had already established a powerful maritime empire. He seized the opportunity, backed by his strong financial resources and navy, united with the Southern Ming forces, and severely damaged the Qing army in the key Jiang defense battle. Then he integrated the south, established a new army and navy, launched two northern expeditions, regained the Central Plains along the way, and attacked Youyan all the way. Finally, he expelled the Qing court, pacified Liaodong, and completed the great cause of unifying the world and rebuilding China.
