In this world, cultivators and demons are always at war. The Demon Kings sent some demons to disguise themselves and live in the Human Villages and Towns.
Their goal was to take care of the humans and build secret bases for the demon armies.
They would continue to live in secrecy and wait for the signal from the Demon Kings before making their move.
These demons that were integrated into the human communities would even enter the Cultivation Families and even Sects with their top-notch disguise skills as spies, leaking valuable information to the Demon Kings.
Therefore, the Sects and Cultivation Families used some special methods to look for the demons every now and then.
Although they were not 100% efficient, they could weed out some of the demons within the sect.
However, every time they use such methods, it costs a lot.
'With a Special Talent to sense the demons within a specific range, that disciple is going to become an asset for the Greenfire Sect.'
