Not until Chen Mu rose and left the private room did his figure disappear.
Shen Qi and Ren Naifei, among others, still had deep fear in their eyes, each staring at the corpse of Sha Xiangtian on the floor, as well as the iron ball that had been forcibly squeezed out onto the table.
"Copper-Steel Skin, Fine Iron Pure Body…"
Shen Qi felt a bitter taste in his mouth.
To knead a knife into this state with bare hands wasn't something that could be done with mere strength. Both the epidermis and muscles had to be extraordinarily strong, such a Copper Skin Pure Body was simply too terrifying. Even three or five individuals who had achieved Body Refinement Perfection would have trouble dealing with it, not to mention how much more fearsome it was to be fearless in group fights, rampaging through crowds like a ferocious beast.
