As Zhang Yushan led her fellow Onmyoji through the streets to clean up wandering souls and stray ghosts, someone seized that moment to break into the Yin Soul Prison built beneath the A City Yin Yang Master Association and unlocked all the cell doors that had been sealing the Five Elements Yin Souls.
The so-called Five Elements Yin Souls refer to those Yin Souls that possess one of the attributes "metal, wood, water, fire, earth" after death. Usually, the attribute carried by these types of Yin Souls is related to the cause of death. For example, water ghosts died by drowning, fire ghosts were burned to death, and earth ghosts were suffocated by sand or buried alive. The resentment these people felt at the moment of death combined with the natural Five Elements to form the Five Elements Yin Souls after they died.
After listening to Zhang Yushan, Chen Hao rolled his eyes and asked doubtfully, "Were only the Five Elements Yin Souls released?"
