In 1935, in the French Concession in Shanghai, antique dealer Qi Yunting found a bronze bell engraved with runes in a ghost market. That night, his shop was attacked by purple zombies. The down-and-out Taoist priest Zhang Taiyi came to the rescue and recognized that it was the lost magic weapon "Soul Bell" in Longhu Mountain. In order to find out the truth, the two met Su Muyu, a female doctor of folklore who had returned from studying abroad. Three unrelated strangers were forced to form a "Strange Society" to jointly deal with the ensuing supernatural crises.
From the lowest purple zombie to the almost demonic immortal, the Strange Society has uncovered the shocking conspiracy of a century-old corpse disaster in life and death adventures. Qi Yunting discovered that the soul-suppressing bell was changing his physique, Zhang Taiyi was carrying the unknown secrets of Longhu Mountain, and Su Muyu used science to interpret ancient Taoism. When the Japanese onmyoji attempt to awaken the thousand-year-old evil at the bottom of the Huangpu River, this motley army must use bell sounds, Taoism and explosives to play the final requiem in the occupied Shanghai.
In this adventure where science and metaphysics collide, love and morality intertwine, each character will face their deepest fears. And that bell that seems to save the world may be the most dangerous curse...
