A young woman, Zhang Sijing, disappeared after climbing Fengdu Mountain. However, the search and rescue team accidentally discovered a sinkhole full of bones and remains.Everyone in the police force learned that this mountain has “steaming clouds and splendid scenery”, attracting countless enthusiasts to risk their lives, and some people specially commit suicide here.Ducheng approached villager Chang Feng to learn about the situation. Chang Feng knew Fengdu Mountain very well and had repeatedly persuaded the climbers to return.
Chang Feng's sister Xiaojuan accidentally fell off a cliff in a mountaineering accident many years ago, which became a regret in Chang Feng's heart.Shen Yi and He Rongyue collected the bones at the scene for restoration. Shen Yi also found the bones of an eight-year-old girl.The police highly doubt that this is Chang Feng's sister.
