The late Ming Dynasty here was a bit chaotic. A mysterious force joined forces with the Jihu Wulin to secretly control the imperial power. The women in the palace were ambitious with the support of the forces behind them. Long Xia, an iron soldier instructor from modern China, pursued her to the Ming Dynasty to find his beloved wife, and passed through the soul of the fifth prince Zhu Youjian. Facing the chaos in the court, and the reincarnation of his beloved wife Zhang Yan'er is about to become his sister-in-law, Long Xia uses the name of "Taizu Tuomeng" to purge the palace with iron-blooded means and assist the emperor to secure the throne. Later, he used thousands of eunuchs and maids as his team to train the army, strengthen the military industry, collect people and materials, and sail out to sea to rebuild the sun, moon, mountains and rivers in Ryukyu. The trapped dragon in the past finally emerged among the thousands of miles of waves, carving out a new sea map belonging to China.
