One night of wind and rain, Jing Xiaohou died suddenly in the study. His death was in a strange manner, leaving only a few riddle words, which shocked the capital.
Shen Jingchen, the Shaoqing of Dali Temple and the official of the Zhencha Si, was ordered to conduct a thorough investigation. He is dark and solemn, and his mind is like an abyss. A murder case in the Hou Mansion revealed old secrets, household plots, mysterious forces and murderous intentions.
