Merlin's mysterious relief sculpture was passed down since the generation of Molta Empire. Its origin had been a myth until now. It seemed to have no other effect except for improving one's physique.
As one's physique reached a certain point, further improvements would become exceedingly difficult. Merlin's physique had not been improved for a long time now despite practicing the relief sculpture regularly.
Now that he sensed that his body was experiencing some sort of change, Merlin would naturally not give up his practice. Thus, he began his practice according to the posture of the fourth relief sculpture.
Merlin knew the posture of the fourth relief sculpture by heart, so he could easily replicate the mysterious yet complex postures.
Normally, Merlin would only practice the posture once; however, he felt that there seemed to be endless energy oozing perpetually from his body today.
