This was Kong Xiang's primary training method for cultivating his physique.
Strenuous training under the effect of gravity allowed him to exhaust the latent potential of the natural body strengthening treasures he consumed. At the same time, the specific set of movements Kong Xiang was making right now allowed the energy to flow smoothly in a certain pattern across his body, slowly refining his bones and organs.
Slowly, Kong Xiang's body expelled some impurities which formed a layer of dirt on the surface of his body.
Outside the training chamber, Master Zhang monitored Kong Xiang's movements and activated a mechanism.
BOOM.
Mid-pose, Kong Xiang suddenly felt the air around him congeal as the gravity increased yet again. He hurriedly stabilized his footing and resumed his punching routine, albeit slower.
