In the middle of the Tang Dynasty, Jiedushi An Lushan and Shi Siming rebelled and wanted to overthrow the rule of the Tang royal family. After the rebellion was put down, Suzong established the Kirin Division, an agency in charge of world intelligence, to be responsible for the investigation of major cases. Qinglong Envoy Li Xuanjing was originally a young detective of the Qilin Division, but due to the death of his master Shen Qinglian, he was imprisoned on death row for seven years and suffered unjust injustice. Seven years later, the Buddhist picture painted by Shen Qinglian reappeared, but it was used by the murderer to imitate the crime. In order to find out the truth of the case, Li Xuanjing was released from prison and found out the Buddhist patterns together with Sang Yeli, a new agent who had just arrived in Qilin Division. After identifying the Buddhist patterns, Li Xuanjing encountered the case of the shape-shifting man in Netherworld Town, the case of the Nanguo Shark Man, the case of Peony Overturning the Country, and the case of Chang'an Beauty Lantern. During the investigation process, Li Xuanjing discovered that there was an invisible hand that dominated the occurrence of these cases. And everything is related to Shen Qinglian's mysterious death seven years ago...
