The Fourth Layer of the Primordial Infinite True Skill involves the process of opening the acupoints all over the body with the assistance of a strong martial utter will, following the Martial Artist's promotion to Martial Arts Grandmaster and the consolidation of the Grandmaster's will.
Different cultivation techniques result in the unlocking of different acupoints, similar to how the cultivation technique operates along various meridian pathways within the body.
The more acupoints opened, the higher the difficulty and the longer it takes.
Although the Primordial Infinite True Skill involves most of the body's acupoints, Lin Zheyu felt it was still insufficient.
He wanted to integrate various cultivation techniques and open all the acupoints within the human body.
"When I previously studied the Guiyuan Skill, I had a rough idea regarding the methods to open acupoints and conceal my breath."
