On the bank of the Qingshui River, there is a giant cedar tree that is five hundred years old. Two stones were buried under the tree - one was engraved with the Miao family's talisman, and the other was marked with three Han finger marks. In the autumn of the 14th year of Kangxi's reign, Lin Wanshan said to his son before his death: "Don't dig monuments unless absolutely necessary." Four hundred years later, Lin Shan, a master of forestry, returned to his hometown and discovered this "imperial tree" ancient tree on Xianren Cliff. The developer offered a million dollars, and the family meeting got into a heated argument. Lin Shan's grandfather, Lin Nianshan, took out an oilcloth bag from the wall - it was a contract document that nine generations of the Lin family had guarded with their lives. On the yellowed pages, a bloody secret about wood was recorded.
