Pei Yanzhou, the noble son who returned from studying abroad, took over the dilapidated Shen Mansion for a century. The water town in the south of the Yangtze River is covered with fog, and a fire has buried treasure and the mystery of one's life experience. He wanted to build his ancestral home, but he met a mysterious woman named Bai Wanqing who moved into the west courtyard with half a jade lock. She has cold eyes and an evil demeanor. She claims to be a member of the Shen family, but people tell people that the daughter is long gone. The old servant died of illness, the fragments of the book appeared, the accounts were abnormal, and the crisis was looming. Pei Yanzhou peeled off the cocoon, but she became a mystery step by step. Every step closer to the truth makes people feel further away. He used his wisdom to solve puzzles, and she used her arrogance to hide her sincerity. When the secret room is opened and the whispers from the well come true, who is the real heir to the Shen family?
