In his body, specifically in his bones and muscles, a new type of energy was forming.
This was Martial Force, the equivalent of Qi for body cultivators.
Where Immortal cultivators refined spiritual energy in their dantian, Martial cultivators condensed physical power throughout their entire body.
The principle behind Martial Force was based on the concept of biomechanical energy storage.
In the normal world, muscles stored chemical energy and converted it to kinetic energy through contractions.
But in the cultivation world, this process could be enhanced and transformed.
During the Body Refinement Realm, a cultivator tempered their physical body to become stronger and more resilient.
But this was just preparation. The real transformation began at the Force Condensation Realm.
At this stage, the cultivator's body began to function like a spiritual energy battery.
