In a city called Haimen, many stories happened:
On a thunderstorm night, the mother told her five-year-old son the legend of the "Prince of Bohai Bay": In 1995, Xue'er, a truant girl, met Ao Kun, a white-haired boy with dragon horns who claimed to be "the son of the Dragon Emperor" in an abandoned shipyard. The soldiers seek revenge on land; Bai Cheng, the 554th "Baize", and Luo Xin and Du Ya, the exorcists of Kaishu Garden, receive clues about the sudden death of the Dragon Emperor. College boy Chen Shangyuan is also taken away by the mysterious investigator Su Yi. The fates of mortals, dragons and demons intersect in "Shuixi Shuyuan", and the land and sea war and the mystery of the Dragon Palace are imminent.
