Transformed by the mysterious power that manifested during the drone upgrade, Yan Fei's physical attributes had reached an unbelievable level, his strength almost touching the limits of human potential. Currently in a phase of full body strength integration, he was slowly gathering all his power at one point before releasing it explosively. With every gesture or step, his strength exceeded several thousand kilograms.
