What's the difference between Yin and Yang division, boundary division and exorcist division?

Yin and Yang teachers, also known as soothsayers or illusionists, originated in China. Not only do they know how to look at the stars and face each other, but they can also measure directions, know disasters, draw spells and perform illusions. People also realize that invisible forces, such as fate, soul and ghost, have the ability to dominate these things.

Enchanter, a branch of powers, is good at boundary demarcation techniques, such as "square perimeter", "foundation", "knot", "extinction" or "solution". It is just a simple formula, but it can be used for attack or defense. It's just a simple geometric figure, combined with opportunity and terrain, but it can exert great power and is quite ornamental. Reasonable plot and clever coordination demarcation have played an unexpected role.

Exorcists can be understood literally, and killing monsters can be the general term of the first two.

Anyway, no matter how the name hasn't changed, the result is still the same.
