After checking out everything available on the the tower's interface, Aaron climbed into the pod.
Soon a deep sleep washed over him and he couldn't even put up a struggle as it took him.
Three hundred of those crystals turned into a gas like substance and flowed into the tube saturating Aaron with their essence and for the first time ever in centuries, humans stepped back into their evolution ladder.
Deep in sleep Aaron felt like he was naked and being caressed by heavenly beauties, thousands of them. Every inch of his body received a substance that looked like it completed an ancient puzzle in the human genetics.
A minute was all it took for the process to be complete and a young man stepped out of the pod, his eyes wide with amazement as he stared at his body brimming with new found strength, if before he was a killing machine now he was someone built to annihilate.
