At the end of Ming Dynasty and the beginning of Qing Dynasty, the southeast coast was in turmoil. The young man Zheng Kezang (pseudonym Zheng Chenggong, actually the son of Zheng Zhilong and his Japanese concubine) was originally a Confucian disciple who was well versed in the art of war and specialized in swordsmanship. When he lost his sword while practicing swordplay on the Xiamen beach, a dragon vein on the sea surface was triggered, and an ancient jade seal engraved with the seal script of "Prince of Yanping County" surfaced - it was actually a token of the ancient "Haihuang Taoism". Yuxi's awakening gave him the ability to control the waves and condense the energy, command the water tribe, and refine the true energy of the tide, and also quietly activated the "Fuso Divine Hidden Technique" that was dormant in his maternal bloodline. He entered the world as a scholar holding a sword. While forming the "Cangming Camp" to fight against the Qing Dynasty and restoring Taiwan, he also investigated the shocking conspiracy of his biological mother being "carried away to the Qing Dynasty" - it turned out that his father Zheng Zhilong had secretly defected to the Qing court in the early years, and the Yuxi itself was actually the core of the "anti-Qing Xinhuo Formation" set up by the elders of the previous dynasty. The main line spans the battlefields of the three realms of sea, land and air, from the martial arts performance in Kinmen to the decisive battle in Chixiang City. It is finally revealed that the Jade Seal is one of the nine seals of Dayu to control the water and suppress the sea, and the real enemy is the pseudo-cultivation force of the 'Xuanming Sect' who used the hands of the Qing court to harvest the fate of humanity.
