During the Jiajing period, Japanese pirates were raging in the southeastern seaboard, and the land of China was devastated. Modern young man Li Ming accidentally traveled through time, and with advanced knowledge and passion, he emerged from the ruins. From leading the villagers to set traps to repel the Japanese pirates, forming a volunteer army to protect the country, to becoming famous with the great victory in Taizhou, and being recognized by the court to take charge of coastal defense; from reforming the deficiencies of the guard station to build a professional army, building steam warships to build a naval force, to the cross-sea expedition to quell the chaos in Japan and establish order in East Asia. He worked step by step, used iron and blood to clean up the Japanese troubles, and awakened the Ming Dynasty with innovative wisdom.
He introduced high-yielding crops to relieve people's hunger, transformed textile artillery to strengthen the country, created the Gezhi Academy to pioneer science and technology, and opened ocean-going trade to connect the world. During the court game, he joined hands with Zhang Juzheng and Hu Zongxian to break the shackles of conservatism; during his overseas journey, he led his fleet across the four seas to protect his vassals and resist colonization, letting the Ming flag fly in Europe, Asia, Africa and the United States. From a survivor in a corner of the southeast to a leader in reshaping China, Li Ming dedicated his life to helping the Ming Dynasty get rid of internal and external troubles and rise to the top of the world. The light of Chinese civilization once again shined across the world and he composed a song of national rejuvenation that transcended time and space.
