The information from the Ancient Mirror was chaotic and disorderly; as Su Jie meticulously sorted through it, he gained some enlightenment.
The so-called Dharma Form can be simply seen as the weapon of the Primordial Spirit.
However, this weapon is not the usual knives, spears, clubs, or staves but the self-forging of the Primordial Spirit into a Tao form.
For example, the monster images that Su Jie saw in the Ancient Mirror were the Chaotic Creatures from the Tao River, which actually assisted Su Jie in comprehending the Dharma Form.
Because the human Primordial Spirit is too fragile, only by presenting the non-human form of Tao creatures can one achieve the Dharma Form for combat, its outward form resembling a monster.
The Dharma Form requires repeated imprinting of the essence of Tao to take shape.
To condense a Dharma Form, one needs to split the Primordial Spirit, part of which is immersed into the Tao River.
