After many years of cultivation, Su Zimo had already made it a habit to only cultivate the Mystic Classic of the Twelve Demon Kings of the Great Wilderness at night.
He had already attained greater mastery of the Organs Refinement section and had been cultivating the Orifice Clearing section for some time now.
The orifices referred to the seven on a person's head!
For the majority of races, their heads were the most mysterious, important and sensitive part of their bodies. Most beings would die instantly if their heads suffered immense damage.
Legend has it that the Purple Residence, Heavenly Palace and Immortal Stage acupoints were located on the head…
Even the Essence Spirit of the immortal Dao and the Yin Spirit of the Mystic Classic of the Twelve Demon Kings of the Great Wilderness were located in the depths of the head.
However, that was a point Su Zimo had not reached given his current cultivation realm.
