Lin Qinghe, a folk shipping genius, was killed because his family ship was destroyed and his father died unjustly. He resolutely sneaked into the decaying water transportation system and vowed to find out the truth. He started as a humble water transport secretary and struggled to move forward amid the obstacles of corrupt officials, eunuchs, and gentry. He witnessed the huge trauma caused to the country by the cutoff of maritime transportation, and also experienced the blood, tears and struggles of the people at the bottom under the policy changes. Accompanied by his confidante and loyal partners, Lin Qinghe gradually grew from an avenger to a changemaker. Faced with the shocking game between sea ban and sea opening, and the ideological confrontation between sea power and land power, he finally chose to step forward and use the vast East China Sea as a chessboard to launch a thrilling and life-or-death showdown with huge vested interest groups.
This is not only the history of one person's revenge, but also a magnificent picture depicting the rise and fall of the Ming Dynasty's shipping and the changes in the country.
