A fanfiction based on the TV drama starring Zhang Cheng and Ding Yuxi. In the early years of the Republic of China, fog shrouded the seas of Nanyang, where strange incidents occurred one after another. Ships vanished without a trace, coastal residents died in mysterious circumstances, and eerie rumors of “water ghosts gazing toward home” spread like wildfire. The people were terrified, and no one dared investigate the secrets behind it.
The Southern Archives, under the Zhang family, specialized in investigating unsolved mysteries and keeping bizarre cases from public view. Two of its finest secret agents, the bold and decisive Zhang Haiyan and the steady, meticulous Zhang Haixia, were dispatched to Nanyang to investigate a string of strange cases engulfing the entire region.
As they delved deeper, the illusion of ghostly curses was gradually torn away, revealing a vicious human conspiracy. A local warlord with grand ambitions had secretly cultivated a rare, highly poisonous plant called Duskweed and extracted its deadly toxin, spreading it in secret. By staging bizarre deaths, he hoped to sow panic, seize control of the Nanyang seas, and plunge the region into turmoil, all to serve his boundless greed and ambition for power.
Their investigation took them through dangers at every turn. The two faced peril side by side, narrowly escaping death time and again. Then an unexpected crisis struck, leaving Zhang Haixia gravely injured and permanently paralyzed. His former partner was left disabled, a haunting regret and pain Zhang Haiyan would carry for the rest of his life.
The fog had not lifted, and the crimes had not ended. Every scattered case, every trace of poison, and every mystery surrounding the victims ultimately pointed to a bizarre ship drifting in the depths of the Nanyang Sea, where all the truth lay hidden: the Nan'an.
Fog cloaked the sea, and the undertow devoured its victims. As the ship’s long-buried secrets slowly came to light, Zhang Haiyan faced an even deeper conspiracy, a more perilous game, and an ultimate mystery tied to the fate of Nanyang and the destiny of the Zhang family...
