From the mysterious underground palace under the ruins of Nanjing's Glazed Pagoda to the Dragon Vein of the Divine Island deep in the overseas waves, they must uncover layers of lies under the double strangulation of the court and the rivers and lakes, and make the ultimate choice between power, truth and the well-being of the people. This is an epic legend that combines suspenseful detectives, court intrigues, chivalry and ancient secrets.
