After listening to Jiu Li's explanation through the voice call, Li Jing was somewhat taken aback.
A demon that can disguise itself from others is one thing, but one that can also alter its Demonic Qi into Spiritual Qi to deceive others?
That's rather impressive.
It's hard for monsters to make a lot of money in human society; at most, they do ordinary jobs to make ends meet. The main reason is that their Demonic Qi is revealed whenever they take action.
However, those who possess the ability to disguise their Demonic Qi as Spiritual Qi, like Jiu Li mentioned, don't have this problem.
Moreover, as long as they're willing, they can work as patrollers - a high-paying job that also offers the chance to kill those monsters who commit crimes.
It's not difficult for those who have mastered both the offensive and defensive magic skills to bluff their way through the required training for patrollers.
