A true Yin Yang master, through divination, could to a certain extent pursue good fortune and avoid disaster.
This empowered them to make the most optimal decisions when facing choices.
Sometimes, whether they stepped out the door with the left foot or the right foot first, the different choice would represent different fortunes for the day.
Small-scale events like a fight, or large-scale ones like a war, could be predicted in advance through divination.
Of course, the more complex the situation, the deeper the cultivation required.
Moreover, Yin Yang masters possessed a very special ability.
Besides calculating fortunes, they could also calculate, and even change, a person's lifespan.
This was a very sinister power.
A perfectly healthy person without illness or disaster, upon the prediction by a Yin Yang master, could be destined to die within three days, would indeed die for some reason within those three days.
