Jiang Linyuan, the 128th direct descendant of Jiang Ziya, is the youngest Feng Shui master in Shanghai. He is cynical on the surface, but in fact he carries the secret of fishing for dragons for thousands of years.
At the age of twenty-nine, the Big Dipper stars were connected, the sky changed suddenly, and the Nilong Vein, which had been sleeping for a hundred years, woke up at the bottom of the Bohai Bay. The bronze dragon fishing hook passed down from generation to generation of the Jiang family trembled again, and the whisper of blood summoned him to return to the "Youdu" - the ancient tomb of the emperor sealed by Jiang Ziya himself.
At the same time, in the old family home of childhood sweetheart Lin Wan, an ancient well that locks dragons connects the secrets of two time and space. The grudges of the previous generation, the forbidden objects in the copper box, the birth curse on the night of the seven stars... All the clues point to the same end point: under the capital, the dragon hook must reappear.
