Based on the interactions between the five human organs and five elements, namely gold, wood, water, fire and soil, it could constantly trigger one's potential and advance it to the utmost.
Zhang Tie felt this cultivation method was fair and progressive. It was fantastic.

This strand of strength was unusual, with the rising level of the cultivator, in the later phase, when the cultivator collected all the five elements in his battle qi, his battle qi would grow more powerful.
"What's its level? Where did you get it from?" Zhang Tie asked Major General Ford.
