The body cultivation method named "Golden Gang Breaking Mountain" that Xue Qing initially chose for Chu Zheng to select for Zheng Ping, though it follows the most cumbersome, difficult, and painful path of externally refining bones, requiring inhuman endurance and daily training, excels in laying an extremely solid foundation with profound potential.
This is the most primitive and effective method of tempering the physique, using extreme external force, undergoing thousands of refinements, discarding the dross and keeping the essence.
In Chu Zheng's perception, the blood and Qi within Zheng Ping roiled like a great river, the orifices emitted light, and he had already stepped into the Fifth Realm of Martial Path, the Divine Orifice Realm.
