The town that does not often snow snowed heavily on the day the Feng family master passed away. Everyone in the town cried bitterly for this stranger. The young master of the Feng family was imprisoned in the Feng family's ancestral hall by relatives of the Feng family to keep filial piety for the Feng family master. From then on, the young master of the Feng family and the Feng family disappeared into the wind and snow of the small town.
Until it snowed heavily again in the town, a man known as Feng Liya, the young master of the Feng family, returned to the town. All he brought with him was a set of simple books and exquisite tea sets.
The day after the heavy snow stopped, Wang Qiaoer and Lu Yaozhi, who were in charge of the newly built textile factory in the town, were found dead in the secret room of the textile factory. They were fixed in the shape of a worship hall before their death, but their rings were not found at the scene.
Wu Yunsheng, a small town detective who has been known as a madman after wandering in the town for three years, went to the orphanage where Feng Liya was alone after observing the test scene. But when Feng Liya saw Wu Yunsheng, she only lowered her head to make tea and handed Wu Yunsheng a yellowed booklet after drinking tea for a while: "I am the murderer of this case and the murderer three years ago. And this is my evidence."
A yellowed book, a foreigner who surrendered, all the details of the case corresponded, but Wu Yunsheng was still reluctant to close the case: "One thing is missing, only the last one from three years ago is missing."
