Lin Jianlu's life, from the day she received both the inheritance of "Nan Mao and Bei Ma", has set off on a bizarre trajectory. The white snake she rescued as a child gave her the power of a psychic medium, and the ancient books she found in college allowed her to learn the Maoshan thunder method without any teacher. What followed was an endless stream of strange events such as the Mirror Immortal seeking his life and the Pen Immortal's curse. After she solved the campus Mirror Immortal case on her own, the 749th National Institute of Abnormal Phenomenon (749th Bureau) came to her door. Facing the official "recruitment", Lin Jianlu held a homemade snake bone whip and became the "special consultant" of Bureau 749, forming a team with the head of the King of Soldiers who believed in science and a hacker Taoist priest who knew programming. They go deep into the shadows of modern cities and deal with supernatural cases nourished by human desires. However, as the investigation deepened, an "artificial totem" plan planned by Maoshan's abandoned disciples and aimed at swallowing up the national destiny came to light. Lin Jianlu must find the true path to integrate the Northern and Southern Taoism in order to protect everything she holds dear.
