After Su Chen cultivated for a few hours, he remembered the matter of the "Calm Spirit Body Technique".
The experiences on this trip to Country M made him passionate about cultivating the "Calm Spirit Body Technique"!
Because once he cultivates the "Calm Spirit Body Technique", the strength of his physical body will undergo a qualitative leap!
However, to cultivate the "Calm Spirit Body Technique", the first step required is Body Refining, and Body Refining is mainly accomplished through three methods: medicinal herbs assistance, Demon Beast Essence Blood—the essence of Black Dragons and Flood Dragons being the best—and True Fire, especially the Spirit Fire within True Fire!
But Demon Beast Essence Blood and True Fire are practically impossible for him right now; the most feasible method at present is to undergo Body Refining through a medicinal herb bath.
