Why would I want more?
Derek had the confirmation. Tetsci's energy was not immune to the temporal barrier, but the contrary was also true, and so he had to be careful.
Lifting the ground in front of him, it blocked the energy rays from hitting Derek's shield, causing an explosion of mass proportion. It created a no seeing zone, and Derek wanted to take advantage of that.
He used his temporal drift to move out of the temporal distortion shield. He maintained it up to keep Tetsci's demonic hands pressing it down, making him think he was still there on the other side of the dust.
He came back to his form right behind Tetsci.
''It's a battle you cannot win'' Derek whispered to his ears. ''But I will let you draw back if so you wish'' he added with a smile.
Pressing his hand on Tetsci's back, he sided Tetsci's body energy composure, before applying is vaccum energy on him, stiffening the muscles. He was absorbing Tetsci's very own energy.
(Not indefinately, it just renders Tetsci's level energy lower in his body. It is not absorbed by Derek. Vacuum energy is a physical principle that means the energy is dissipating).
Derek sighted Dosu. He heard the name of Vixen.
''Shame for you Dosu, that you would come so low by events. And would you think Vixen would have wanted that? But it is not too late to change your ways, you will see''.
