Watching A'Man's physical strength double in such a short time, Kong Yu widened his eyes in disbelief. Previously, his physical strength was similar to A'Man's, but now A'Man's strength was twice as much as his. How could this not make Kong Yu envious? At the same time, he was very curious about what kind of Body Refining Technique A'Man was practicing. How could it possess such an incredible ability?
Indeed, A'Man was practicing a Body Refining Technique because, from beginning to end, the only thing increased was physical strength. Apart from that, no other power was enhanced. This made Kong Yu certain that A'Man's practice was a Body Refining Technique. This technique was simply heaven-defying and outrageous with such effects. Looking at the skin-and-bones remains of the Tiger Beast, Kong Yu thought that had he known it could double A'Man's strength, he would have kept the beast for himself instead of giving it to A'Man.
