Master said: Going down the mountain to get married is your calamity and your destiny. Lu Tingyuan entered the city with an engagement paper, but what awaited him was not a good match, but a divorce letter and countless cold looks. Everyone thought that this young man from the mountains would bend under the pressure of a wealthy family. But soon, the antique world regarded him as a myth, the Feng Shui world respected him as a master, and the medical world called him a holy hand. When the layers of fog cleared, Lu Tingyuan discovered that from the moment he came down the mountain, a huge chess game spanning two generations and related to the survival of Xuanmen had quietly begun. And he is the one who plays chess.
