In the darkness, endless evils lurk.
Among them, the most common malevolent spirits are wandering evils, their numbers virtually limitless, usually invading human souls and also claiming lives.
Those malevolent spirits that have developed sentience are even more eerie and harder to exorcise.
More crucially, spirits like "Evil Spirits" have gained the ability to "possess."
Those who are possessed—if lucky with their fortune—can be exorcised by temples, but afterwards, their vital essence will be greatly diminished, inevitably leading to severe illness.
However, the fortune of the city guards is usually not so good, because temple workers cannot always accompany the city defense.
And the rule of the City Defense Army is that once a guarding soldier encounters an Evil Spirit and becomes possessed, they must be executed on the spot.
Regarding Zhao Jing's murder last night, the Great Commander had two suspicions.
Either the murderer was possessed by an Evil Spirit.
