The spiritual qi of human cultivators converged at the spiritual platform between their eyebrows.
However, that is not the case for monsters.
The core of their demonic qi gathered below their waist, in their dantian region.
The difference between the two is significant.
According to modern Immortal Learning...
Human cultivation mainly focuses on the soul, with the spiritual qi gathering at the spiritual platform between the eyebrows, which helps to strengthen the spirit.
Monsters on the other hand, mainly focus on the body during cultivation. Their cultivation gathers at the dantian below the abdomen, which helps to strengthen the physical body.
Each has its own advantages and disadvantages, involving a great deal of factors.
Human cultivators do not prioritize physical strength, while monsters struggle to erase their instincts. This is closely related to each party's different cultivation method.
