Since the Yongle Emperor took the throne, the court has devoted the strength of the entire nation to building an ocean-going fleet, determined to spread the glory of the Great Ming across the seas. Zheng He, acting on the emperor’s command, leads this unprecedented armada on seven voyages to the Western Seas, trading with nations across the world. Yet only a handful of people know that the fleet’s true mission is not trade or diplomacy, but to suppress the terrifying entities stirring beneath the deep sea.
Legend has it that Guixu is the abyss beneath all seas, devouring every living thing and even time itself. Six hundred years ago, Yu the Great offered his own flesh and blood to seal the gates of Guixu. Now the seal is weakening, and the Canglong has awakened. Only the secret arts guarded for generations by the Zhenhai Bureau, together with the fleet’s cinnabar cannons, can hold back the impending catastrophe.
