Couldn't have that. So I raised my right hand, clenched in a fist, baring four triple-wire bands, one on each finger. With a thought and a word I released the kinetic energy stored in one of the rings. It hit the goon like a locomotive, slamming him back and to the floor with a very satisfying thud.
I turned and kicked the stunned first goon in both shins, hah, then placed one of my heels against his hip and shoved him to the floor. He crumpled.
