His left arm was nearly dead, whatever the knife was crafted from or magicked with had seen to that. His opponent, still sideways in the dirt, had been sent on a mission and whatever it was, he was damn near close to completing it with startling effect.

Tre'Yan slipped himself back to a boxing position, left arm barely raised in defense, right hand poised to strike. He bent at the knees, posing himself to move again, should he need it. His muscles in his right arm tensed, aching for a release. It was a good thing too, Cho had no intentions of messing around. 

The man sprung up and forward, executing a slash that was intended to travel the diagonal length of Tre'Yan's body, starting from lower left to upper right. Having no intention of feeling the metal of that blade again, he quickly leapt a small distance back.

His body had to keep moving, as Cho came forward as the blade whistled back, with a right to left slash at shoulder height. Being a boxer, he was proficient at having to dodge strikes that came in rapid succession. Cho was trying to kill him, and Tre'Yan needed to survive. 

He ducked, and decided to execute the end game of this match. 

He twisted his hips forward, generating the momentum he would need to fire off a vicious uppercut. He combined it with his rising motion, gathering the momentum from the uprising to use. Tre'Yan could dent steel walls at the fullest extent of his powers, something he hoped would help him here. The plan was near perfect, even if modified. His rise saw the firing of an explosive, in relative terms, uppercut that was aimed at the chin of Cho. 

Tre'yan's arm would snake back swiftly, albeit it, faster if he connected. Assuming his opponent's head was rocketed back, he would be in prime position for the end of the deadly combination - a right hook. Usually it was left uppercut, right hook, but his left arm was basically dead in the water.
